Blue-light cystoscopy and narrow-band imaging in bladder cancer management
Zhijiang Zang, Qinghui Wu, Edmund Chiong
September-October 2019, 52(5):155-160
Despite the high resolution of modern imaging technology including computed tomography and magnetic resonance imaging, cystoscopy remains the gold standard method for detecting bladder cancer. Cystoscopy is conventionally conducted with white light visualization, and the pitfalls of white light cystoscopy are well-recognized. Novel technologies to enhance visualization of bladder lesion have emerged during the past 20 years. Among them, blue-light cystoscopy (BLC) and narrow-band imaging (NBI) are the most promising and well-studied. Many clinical trials have suggested the benefit of these two technologies. In this review, we aim to summarize the data, evidence, and current role of BLC and NBI in clinical practice.

Chronic neuropathic pain following inguinal hernia repair
Toufik Berri
July-August 2019, 52(4):111-121
Since recurrence rates have been considerably reduced with mesh repairs, chronic pain has recently become the main concern after inguinal hernia repair (IHR), with significant impact on patient satisfaction, societal cost, and quality of life. Some 31% of all patients with persistent postsurgical pain develop neuropathic pain (NP) after IHR seeing that the inguinal nerves that cross the surgical field can directly or indirectly be damaged. Because of the multiplicity of the risk factors and the complexity of the pathophysiological mechanisms, substantial attention has been devoted to the multidisciplinary approaches and to the preventive measures. More clinical trials are needed to improve the level of evidence of the use of pharmacological, surgical, and interventional procedures in both prevention and treatment of chronic NP following IHR. In this article, the current objectives are to review the incidence, risk factors, pathogenesis, diagnosis, prevention, and treatment of chronic NP after IHR.

Inhibitory effect of methamphetamine on intracavernous pressure in rats
Tao-An Chang, Bang-Ping Jiann
March-April 2018, 51(2):63-68
Background: There is a paucity of animal study investigating the effect of methamphetamine (METH) on penile erection in spite of its worldwide population. Aim: We investigated the changes of intracavernous pressure (ICP) elicited by cavernous nerve stimulation after a single and repeated dosing of METH in male rats. Methods: Rats were randomly assigned to five treated groups and one control group with each group having 3 rats. Rats in treated group 1, 2, and 3 received a single dose intravenous injection with 0.1, 1.0, and 10.0 μg/kg METH, respectively. Rats in treated group 4 and 5 received an intraperitoneal injection with 1.0 and 5.0 mg/kg METH four times daily for two weeks, respectively. ICP was measured during penile erection elicited by cavernous nerve stimulation. Expression of neural nitric oxide synthase (nNOS) was measured in the cavernous nerve and muscle after single and repeated dosing. Main Outcome Measures: The primary outcome measure was the ΔICP/mean arterial pressure (MAP) and the secondary was the expression of nNOS in the tissue. Results: The ΔICP/MAP increased slightly in group 1 rats and decreased substantially in group 2 and 3 rats compared with the baseline. A single dose of METH within the range of 0.1 to 10.0 μg/kg exhibited an inhibitory effect of ICP (%). The ΔICP/MAP significantly decreased in group 4 and 5 rats after repeated dosing of METH, compared with that in group 3. The expression of nNOS significantly increased in the cavernous muscle after single and repeated dosing of METH compared with the control. Conclusions: The preliminary results suggested that a single dose of METH exhibits an inhibitory effect on ICP and repeated dosing of METH exerted a greater inhibition than a single dosing. However, these results need further study.

Long-term follow-up for patients with colonic perforation due to colonoscopy: From clinical and medicolegal viewpoints
Tzu-Chun Chen, Ji-Shiang Hung, Been-Ren Lin, John Huang, Jin-Tung Liang
November-December 2017, 50(6):195-199
Background: This retrospective study analyzes the clinicopathologic features and medicolegal debates on this complication. Methods: There were 29 records of colonic perforations, whose charts were retrospectively reviewed. Results: A total of 26 perforations occurred as a result of diagnostic colonoscopy, and three occurred after therapeutic colonoscopy. Eight perforations were diagnosed immediately during the procedure, based on the revelation of intraperitoneal organs with bleeding of bowel wall on the colonoscopic monitor. Twenty patients were diagnosed as a hollow-organ perforation within 12 h after the completion of colonoscopy, whereas one perforation was found more than 24 h after colonoscopy. Abdominal pain and distention are the most common symptoms. All the patients underwent emergency surgery. One patient had wound infection, and two patients had leakage of the repair site. One patient aged 80 died of pulmonary septic complication. Our hospital paid all additional expenses which were not covered by the National Health Insurance Bureau for all patients, ranging from 500.0 to 1500.0 US dollars (mean ± standard deviation, 549.0 ± 145.0 US dollars). Four patients (13.8%) asked for further compensation of the complication and one litigated. Conclusions: Iatrogenic colonic perforation due to endoscopy is potentially lethal, especially for aged patients. Some patients and their family viewed the perforation as malpractice and asked for compensations. Usually, the primary repair of the perforation site is safe, and long-term follow-up reveals no sequelae after adequate treatment.

Eighty percent partial splenic embolization is a safe and effective procedure in management of cirrhotic hypersplenism
Bor-Gang Wu, Andy Shau-Bin Chou, Guan-Jin Ho, Ming-Che Lee
May-June 2017, 50(3):101-106
Background: Partial splenic embolization (PSE) has been proposed in patients with cirrhotic hypersplenism in cases when thrombocytopenia causes clinical manifestations or if there are contraindications to subsequent therapeutic procedures. We provide a retrospective review of the safety and favorable treatment results of 80% splenic embolization in patients with cirrhotic hypersplenism in our institute. Methods: Thirteen consecutive patients with cirrhotic hypersplenism were included in a 4-year study period. The indications for PSE were as follows: percutaneous treatment of hepatocellular carcinoma (HCC) (n = 3), transarterial chemoembolization plus hepatic arterial infusion chemotherapy for HCC (n = 2), preparation for major surgery (n = 5), and severe purpura (n = 3). PSE was performed with up to 80% reduction of splenic blood flow by radiological intervention. A tight protocol of prophylactic antibiotics was introduced. Patient demographics, procedure-related complication, and efficacy of PSE were analyzed. Results: The mean follow-up time was 26.1 ± 12.3 months. All the patients tolerated the procedure. The minor complication of postembolization syndromes such as fever and abdominal pain occurred in 38.5% and 61.5% of patients, respectively. Only a major complication of transient ascites needs diuretic therapy occurred in two patients. Pre-PSE platelet count was 35,077 ± 11,049/mm3, and it significantly increased 1 week after PSE, with a mean increase of platelet count to 384% of pre-PSE level (P < 0.001). The effect of PSE sustained to maintain the platelet count significantly at a mean level of 112,636 ± 33,341/mm3, 114,571 ± 30,696/mm3, and 118,000 ± 31,035/mm3 at 12, 24, and 36 months, respectively. Conclusion: Our series demonstrated that 80% PSE is a safe and effective method to treat patients with cirrhotic hypersplenism. It could not only increase the platelet count within a short period of time but also maintain it at an acceptable level for a long duration. Under a tight protocol of prophylactic antibiotic and delicate technique of PSE, there was no any septic complication developed in our series.

Prognostic factors for radial nerve palsy associated with humeral shaft fracture
Yen-Yi Hoa, Lee-Wei Chen, Kao-Chang Yang, Kuei Chang Hsu, Wen-Chung Liu, Cheng-Ta Lin
January-February 2017, 50(1):1-9
Background: Radial nerve palsy (RNP) associated with humeral shaft fracture is a common injury pattern in trauma patients. The management of RNP associated with humeral fractures in high-energy trauma is controversial and poses a challenge to surgeons treating it. Purpose: Based on a review of our experience over the past 15 years, we determined the prognostic factors of radial nerve recovery after humeral fractures, evaluated the diagnostic role of nerve conduction studies and electromyography (EMG), and compared the outcomes of different treatment strategies. Materials and Methods: The data of 26 patients having RNP associated with humeral shaft fractures over a 15-year period were collected for a retrospective review. For statistical analysis, the patients were divided into groups on the basis of their recovery from RNP and the treatment strategies used. Results: The incidence of RNP associated with humeral fractures was 2.05%. In total, 91.3% of patients with primary RNP in this series experienced high-energy trauma. Spontaneous recovery was observed in 9 of 26 patients (34.6%). Radial nerve lesions were found in 7 of 8 patients with high-energy trauma. The severity of humeral shaft fractures was found to be a significant prognostic factor for spontaneous recovery from RNP. The rate of spontaneous recovery was significantly higher in the AO Foundation and Orthopaedic Trauma Association Type A humeral shaft fractures (P = 0.028) and lower in Type C fractures (P = 0.055). The median time to detect initial radial nerve recovery using EMG was 34 and 75 days after injury (P = 0.033). In high-energy trauma, tendon transfers were associated with more predictable outcomes than nerve reconstruction (favorable functional recovery: 100% for tendon transfers vs. 25% for nerve reconstruction, P = 0.007). Moreover, tendon transfers were associated with a shorter overall treatment duration (median treatment duration: 190 days for tendon transfers vs. 422 days for nerve reconstruction, P = 0.007). Conclusion: The prognosis of RNP associated with humeral shaft fractures in high-energy trauma is less favorable, with a low rate of spontaneous recovery. EMG is helpful for the early detection of initial nerve recovery. The outcomes of tendon transfers in high-energy trauma are predictable and the treatment duration is shorter. First-intention tendon transfer is a reasonable treatment strategy in patients with difficult nerve exploration, lower requirement for functional recovery, and lower compliance with treatment.

Ulnar nerve injury due to lateral traction device during shoulder arthroscopy: Was it avoidable?
Vivek Pandey, Sandesh Madi, Kiran Acharya
November-December 2017, 50(6):220-222
Most of the nerve injuries reported during shoulder arthroscopy in a beach chair, or lateral position is related to inappropriate patient positioning or excess traction. The lateral decubitus position is more vulnerable for traction-related neuropraxia. The present case serves as an important lesson from an avoidable situation of “having a one track mind” of the surgical team during the arthroscopic repair of shoulder instability performed in the lateral decubitus position. The operating surgeon must supervise the appropriate positioning of the patient on operation table and adequate padding of vulnerable bony points before beginning of shoulder arthroscopy to prevent any position-related nerve injuries. This is probably the first case to illustrate an unusual cause of ulnar nerve compression particularly related to the use of an additional traction device in the arthroscopic repair of shoulder instability performed in lateral decubitus position, which has not been previously defined.

Callus formation in bone fractures combined with brain injury in rat
Yu-Ping Chen, Hsin-Chin Shih
March-April 2017, 50(2):57-62
Objective: The objective of this study was to determine the speed of bony union and the serum levels of biomarkers in the setting of bone fractures combined with brain injury. Materials and Methods: In this study, Sprague–Dawley rats were randomized into four groups: sham, brain injury, bone fracture, and bone fracture plus brain injury groups. The serum levels of biochemical markers, namely, nerve growth factor (NGF), Wnt-3a, Dickkopf-related protein-1, receptor-activator of NF-κB ligand, and adrenocorticotropic hormone (ACTH), were measured on the days 1, 3, 7, and 14 following injury. Bony union was evaluated using radiographs every week for 6 weeks. Results: Compared with the brain injury group and bone fracture group, the radiographs of the bone fracture plus brain injury group revealed enhanced callus formations in week 2. From week 3, the callus formation did not differ significantly among the groups. The serum levels of the biomarkers varied at different time points. The serum levels of NGF on days 1 and 3, Wnt-3a on days 3 and 14, and ACTH on days 1, 3, and 7 were significantly higher in the bone fracture plus brain injury group than in the bone fracture group. Conclusions: Brain injury increases callus formation in simultaneous bone fracture. Considering the time point, early NGF, Wnt-3a, and ACTH elevation might be associated with early callus formation enhancement. The results indicate that these brain injury-induced biomarkers might play crucial role in accelerating bone healing.

Isolated tuberculous epididymitis
Shao-Ming Chen
March-April 2017, 50(2):74-76
Isolated tuberculous epididymitis (ITE) is an uncommon disease that is often incorrectly diagnosed as the more common epididymo-orchitis. ITE is usually treated using long-term general parenteral or oral antibiotics. The nonspecific nature of laboratory tests for ITE renders its diagnosis challenging. Here, we report the case of a 65-year-old male patient who presented with a 6-month history of the left scrotal swelling. He was initially treated with general oral antibiotics but without any noticeable improvement. On the basis of his symptoms and signs, laboratory test and imaging results, and biopsy, we finally made a diagnosis of ITE. After receiving appropriate treatment, the patient was cured completely without the need of surgical intervention.

Experience in traumatic small bowel perforation management
Ping-Tze Chen, Hong-Ming Chao
January-February 2018, 51(1):32-37
Small bowel perforations due to blunt abdominal injury are rare. In this study, we compiled five cases of traumatic small bowel perforation and then analyzed a number of the prognostic factors. Elapsed time to surgery was identified as the most important prognostic factor, due to the risk of peritonitis. Laparoscopy surgery appears to be a safe, effective procedure in cases where the diagnosis is uncomplicated by other major problems, such as lacerations to the liver or spleen.

Chloroquine induces lysosomal membrane permeability-mediated cell death in bladder cancer cells
Hung-En Chen, Ji-Fan Lin, Yi-Chia Lin, Shen-I Wen, Shan-Che Yang, Te-Fu Tsai, Kuang-Yu Chou, I-Sheng Thomas Hwang
July-August 2018, 51(4):133-141
Background: Chloroquine (CQ) is recognized as a potent adjuvant when combined with other chemotherapies to treat cancers. However, the effects of a single treatment of CQ on bladder cancer (BC) cells have not been investigated. Methods: The growth and viability of CQ-treated BC cells were examined. The lysosomal morphology was detected using LysoTracker. The induction of lysosomal membrane permeability (LMP) was detected by acridine orange (AO) translocation, and cathepsin B and D release. The expression of the bid, caspase-3, and cytosolic cytochrome C (Cyto. C) in CQ-treated cells was detected by the Western blot. The pepstatin A and E64d were used to attenuate CQ-induced LMP. Results: A single dose of CQ treatment induced BC cell death, and attenuated by pepstatin A and E64d. The diminishing of fluorescent in CQ-treated cells stained with LysoTracker, suggesting that CQ targets lysosomal functions. This was further supported by increased AO translocation and the releasing of CatB and CatD into the cytosol. The increased level of cleavage bid and cytosolic Cyto. C indicated mitochondrial outer membrane permeabilization and subsequently leading to apoptosis induction judged by the increased level of activated caspase 3. Conclusion: CQ-induced LMP that enhances apoptosis and ultimately leading to BC cell death. The study results demonstrated for the first time that single CQ treatment against BC cells by inducing LMP and subsequent mitochondria membrane permeability that trigger apoptosis, making it a potential treatment for BC therapy in the future.

Hyperbaric oxygen therapy for hemorrhagic radiation cystitis
Kung-Hung Lin, Hui-Chieh Lee, Wen-Shyan Huang, Po-Wei Huang, Seng-Chung Ke, Man-Gang Lee
March-April 2017, 50(2):52-56
Background: Radiation cystitis with macroscopic hematuria is a frustrating clinical problem for urologists. Since 1985, hyperbaric oxygen therapy (HBOT) has been applied as a treatment for radiation cystitis with macroscopic hematuria; numerous studies have shown that this treatment has favorable results. Purpose: The purpose of this study was to elucidate the HBOT affected the clinical outcomes and treatment of hemorrhagic radiation cystitis (HRC). Methods: Between November 1989 and June 2014, 42 patients (39 women and three men) with HRC were treated with hyperbaric oxygen at a pressure of 2.5 atmospheres absolute, breathing 100% O2for 120 min in a multiplace hyperbaric chamber. Results: After an average of 38 hyperbaric oxygen sessions, macroscopic hematuria was completely halted in 35 patients (83.3%) and markedly decreased in three patients (7.1%). A comparison of cystoscopic findings before and after HBOT showed significant decreases in both hemorrhagic sites and telangiectasis of the bladder mucosa. The mean follow-up was 20.7 months (range: 3–49 months). No cases exhibited evidence of barotrauma or oxygen toxicity. One patient underwent a urodynamic study both before and after HBOT, with several changes in bladder function observed after HBOT: urine peak flow increased from 12.8 mL/s before HBOT to 15.0 mL/s after HBOT and urine mean flow increased from 6.5 mL/s to 8.9 mL/s. Urine voiding time decreased from 40.0 s to 28.0 s, urine flow time from 39.0 s to 28.0 s, time to peak flow from 15.0 s to 8.0 s, and voided volume from 251 mL to 248 mL. Conclusion: The results of this study suggest that early application of HBOT is a safe and effective treatment method for HRC. Whether HBOT is beneficial to urinary bladder function requires further study with a larger patient cohort enrolled.

Distal pancreatectomy and celiac axis resection for pancreatic body carcinoma involving celiac artery
Shih-Chun Chang, Yu-Yin Liu, Tse-Ching Chen, Cheng-Huei Tseng, Ta-Sen Yeh
January-February 2017, 50(1):28-31
Pancreatic body or tail cancer with invasion to major vessels, including the common hepatic artery and the celiac artery, was previously considered to be unresectable. However, an increasing number of surgeons have aggressively adopted distal pancreatectomy, splenectomy, and celiac axis resection (DP-CAR) in this scenario to attempt curative resection, thus improving long-term survival. In this paper, we present the case of a 45-year-old man with pancreatic body cancer invading the celiac axis who underwent DP-CAR with negative margins (R0) and subsequently exhibited an uneventful postoperative course. We also reviewed literature, which unequivocally demonstrates a comparable oncological outcome between pancreatic body or tail cancer with and without celiac artery resection. To the best of our knowledge, our study is the first documented case in which DP-CAR was successfully performed in Taiwan.

Traumatic scrotal anal fistula
Shao-Ming Chen
May-June 2017, 50(3):107-109
Scrotal wounds are most often related to infection or allergy and are generally identified in urology clinics. Topical medications, which are generally applied initially to the wound, can assist with spontaneous healing without any sequelae. However, further workup is sometimes required if the wound does not heal properly. Herein, we present two cases which were finally diagnosed as traumatic scrotal anal fistulae, for which surgical excision was clearly indicated.

Kimura's disease
Manish Swarnkar, Anand Agrawal
January-February 2018, 51(1):26-28
Kimura's disease (KD) is a benign chronic inflammatory disorder attributed to an immune-mediated hypersensitivity which often presents as a tumor-like swelling in the head and neck region with or without lymphadenopathy, associated with hypereosinophilia and elevated serum immunoglobulin E. Most cases have been described predominantly in Chinese and Japanese people. KD has been confused with angiolymphoid hyperplasia with eosinophilia, from which it probably should be distinguished as a separate entity. The course is usually benign except for the potential cosmetic disfigurement. The diagnosis may be suggested by a fine-needle aspirate but is established by a biopsy. A case of KD in a 42-year-old male with recurrent left submandibular swelling is presented together with a brief review of the literature.

Long-term surgical outcome of median nerve injuries
Mohammadreza Emamhadi, Hamid Behzadnia, Sasan Andalib
May-June 2019, 52(3):71-75
Background: Median nerve integrity is a prerequisite of normal hand function. The median nerve is a frequently injured nerve, and recent evidence indicates that nerve surgery may produce acceptable outcomes. The present study provides a framework of long-term surgical outcomes of median nerve injuries and specifies independent predictors of motor and sensory recovery. Materials and Methods: In the retrospective study, patients with median nerve injuries undergoing the nerve surgery were reviewed. Mechanism of injury, level of injury (arm, elbow/forearm, and wrist), type of injury and lesion, type of surgical repair, and the time interval from injury to surgery were assessed. The long-term follow-up of motor recovery, sensory recovery, and quality of life was done. Results: A total of 106 cases with median nerve injuries undergoing nerve surgery were included in this study. Most injuries were at wrist level with a higher frequency of sharp and not in continuity lesions. There was a significant association between the three outcomes (motor recovery, sensory recovery, and quality of life) and smoking, addiction, type of injury, type of lesion, and type of nerve repair. There was a significant correlation between quality of life and muscle force recovery and between quality of life and sensory recovery. Muscle force recovery was significantly correlated with sensory recovery. Conclusions: The findings of the present study suggest that male and young subjects, lesions in continuity, and injuries treated without grafting may show better surgical outcomes.

Shah-Waardenburg syndrome
Rahul Gupta, Dinesh Kumar Barolia, Ramesh Tanger, Lila Dhar Agrawal, Arun Kumar Gupta, Ram Babu Goyal
September-October 2017, 50(5):163-168
Introduction: Shah-Waardenburg syndrome (SWS) is WS associated with Hirschsprung's disease. It is very rare with <80 cases reported in the literature. Aim: The aim of this study was to describe our experience with SWS. Methods: The records of patients admitted to our tertiary care pediatric surgical institute between 2011 and 2015 were retrospectively reviewed. All patients with histopathological diagnosis of Hirschsprung's disease were studied. SWS was identified as per the diagnostic criteria proposed by the Waardenburg consortium. Results: There were 202 patients diagnosed with Hirschsprung's disease during 5 years. We identified three male patients fulfilling the diagnostic criteria for WS (white forelock with the involvement of eyebrows and eyelashes, pigmentary disturbances of the iris, and broad high nasal root). All presented in the neonatal period with clinical and radiological features of small bowel obstruction. Family history (sibling) of SWS was seen in one of the neonates. Exploration revealed distended jejunal and ileal loops in all of them; colon contracted and unused (microcolon). Multiple seromuscular biopsies were performed from colon in all 3 neonates. Initial ileostomy was performed in case 2 and case 3. In case 1, the right transverse colostomy was done primarily as total colonic aganglionosis (TCA) was not expected (absence of transition zone in the early neonatal period) and also frozen section facilities were not available. It was followed by ileostomy (second surgery) about 15 cm proximal to the ileocecal junction as colostomy was not functioning adequately. The histopathology of gut biopsies revealed aganglionosis in the entire colon, confirming the diagnosis of TCA in all the cases. Out of three patients in our study, two neonates died in the postoperative period, while third case succumbed due to severe episodes of ileostomy diarrhea. Conclusion: A patient of WS presenting with neonatal intestinal obstruction or constipation since birth should be evaluated on the lines of SWS . Patients with SWS have a higher incidence of TCA or long-segment Hirschsprung's disease. In SWS when transition zone is not clear, an ileostomy would be preferable in view of nonavailability of frozen section.

A randomized clinical trial comparing a collagen-based composite dressing versus topical antibiotic ointment on healing full-thickness skin wounds to promote epithelialization
Hsin-Chung Tsai, Hui-Ching Shu, Li-Chuan Huang, Chuan-Mu Chen
March-April 2019, 52(2):52-56
Background: Acute traumatic wounds are a common and distressing event for patients presenting to plastic surgery clinics. There are no definitive conclusions regarding the benefits of collagen-based wound care products toward the application on full-thickness wounds compared to traditional ointment or gauze care. In this clinical trial, we aimed to define the potential benefits of collagen-based dressings on healing through the comparison of collagen-based composite dressings with antibiotic ointment dressings. Methods: This was a randomized two-tailed controlled clinical trial. The acute full-thickness wounds underwent wound cleansing, debridement, and were secured with different dressings in both experimental and control groups. The wounds were subsequently photographed weekly, and the wound areas were calculated using ImageJ software to evaluate wound healing rate. Results: The results demonstrate that the collagen-based triple layer composite dressings which consisted of silver sheet, collagen sponge, and foam films promoted better epithelialization and healing than antibiotic ointment treatment. Collagen supplementation improved wound healing and epithelialization by providing a dry environment during the late stage of wound healing. Conclusion: We demonstrated that the collagen-based triple layer wound dressing could potentially increase the healing rate when used for traumatic full-thickness wound care compared to the conventional antibiotic ointment dressing, providing a new prospective in the future applications of wound care.

The use of perforator flaps for the reconstruction of sacral defects: Ten-year experience
Hao-Yu Chiao, Shun-Cheng Chang, Chang-Yi Chou, Yuan-Sheng Tzeng, Shyi-Gen Chen, Chin-Ta Lin
July-August 2018, 51(4):142-147
Background: Despite advances in reconstruction techniques, sacral defects continue to challenge surgeons. The perforator flap preserves the entire contralateral side as a future flap donor site and the gluteal muscle itself on the ipsilateral side to minimize donor-site morbidity. Materials and Methods: Between April 2003 and March 2013, data obtained from 60 patients with sacral defects reconstructed with perforator flaps were retrospectively analyzed. Results: We analyzed the sacral defects reconstructed with three different perforator flaps into the following groups: group 1, 30 patients with superior gluteal artery perforator flaps, (average flap size was 83.8 cm2); Group 2, 19 patients with parasacral perforator flaps (average flap size was 94.2 cm2); and Group 3, 11 patients with inferior gluteal artery perforator flaps (average flap size was 85.8 cm2). The overall flap survival rate was 93.3% (56/60). Conclusion: Perforator flaps are a reliable option for soft-tissue defect reconstruction as they provide a sufficient amount of tissue to cover large sacral defects. We recommend perforator flaps as a viable alternative in the management of sacral defects that cannot be reconstructed with primary closure or local fasciocutaneous flaps.

Laparoscopic-assisted peritoneal dialysis catheter insertion with two 5-mm ports: Complications and outcomes of 30 cases
Kung-Ning Hu, Kun-Hung Shen, Chih-Chiang Chien, Chien-Liang Liu
July-August 2017, 50(4):131-134
Introduction: End-stage renal disease has high prevalence in Taiwan, and peritoneal dialysis (PD) is one of the effective treatments. Although the open catheter placement method is more popular, the laparoscopic method is proven to be superior. We present our initial experience with laparoscopic PD catheter insertion. Materials and Methods: We set one 5-mm trocar over the periumbilicus with another assisting 5-mm trocar in a region about 3 cm lateral to the umbilicus. Abdominal exploration using laparoscopy is performed, and enterolysis is also performed if needed. The PD catheter is inserted through the assisted trocar deep into the Douglas pouch under vision. Finally, we check the final condition under laparoscopy and close the wound. Results: A total of thirty patients (median age 56.5 years old, 15 women) underwent this procedure. No intraoperative complications were noted, and the mean operation time was 32 min. Two postoperative complications were found (2/30, 6.7%). Delayed bleeding was noted due to abdominal wall vessel injury while setting the trocar. The vessel was sutured under laparoscopy, which stopped the bleeding. The other complication was tube dysfunction due to omentum wrapping. Laparoscopic revision of the tube was performed. All the complications could be resolved, and the PD was continued. The mid-term tube function at follow-up (at least 16 months) was acceptable in all cases. Conclusions: Laparoscopic-assisted PD catheter insertion is a feasible procedure that can reduce wound pain with acceptable PD function.

Treatment strategies for locally advanced rectal cancer with synchronous resectable liver metastasis
Youn Young Park, Nam Kyu Kim
January-February 2018, 51(1):1-8
Approximately one-third of patients with colorectal cancer are estimated to be diagnosed with synchronous liver metastasis (LM). The only method to get cured is to achieve curative resection for both primary and LM. When it comes to locally advanced rectal cancer with synchronous LM, determination of the treatment strategy for each individual is a quite complex procedure, because it demands sophisticated consideration for both local and systemic control. Timing for the application of systemic chemotherapy (CTx), determination of a chemotherapeutic agent, radiation dose and fractions, and sequencing of preoperative treatment and surgeries are all essential components for establishing optimal treatment strategies for the patients with this disease. In this article, treatment strategies proposed in the literature will be reviewed in the light of oncologic outcomes and treatment toxicity with their possible advantages and disadvantages. Owing to a lack of concrete evidences for the best strategy, this article can guide authors to a better way of determining more tailored treatment for each individual.

Zhu-Jun Loh, Kuo-Ting Lee, Wei-Pang Chung, Wen-Chung Chen, Hsueh-Li Kuo, Po-Jun Chen, Hsi-Huei Lu, Hui-Ping Hsu
March-April 2017, 50(2):69-73
Secondary colon malignancy is rare and has a nonspecific presentation. Breast cancer is the second most common malignancy that metastasizes to the gastrointestinal (GI) tract. Here, we present the case of a 54-year-old woman diagnosed with breast cancer and synchronous colon metastasis through a positive result obtained from stool occult blood screening. Colonoscopy revealed a subepithelial tumor of the colon. Biopsy revealed metastatic cancer with positive cytokeratin and GATA-binding protein 3 staining, as well as negative caudal-type homeobox 2 staining. A palpable right breast mass with nipple retraction was found, and invasive lobular carcinoma (ILC) was diagnosed. Multiple bone, left adrenal gland, para-aortic lymph node, and contralateral breast metastases were detected. Multimodality treatment involving systemic chemotherapy, hormone therapy, and modified radical mastectomy was applied. In our clinical experience, colon metastasis from breast cancer is rare and usually mimics primary colon cancer. High-alert speculation and aggressive biopsy for patients with abnormal GI bleeding are indicated for diagnosis. Patients with colon metastasis from ILC of the breast have a poor prognosis. Therefore, multimodality treatments should be applied to improve their prognosis.

Background: Infection-induced inflammatory response might be aggravated by surgery insults. The clinical presentation of Surgical Intensive Care Unit (SICU) patients might be different from medical critically ill patients. Purpose: To evaluate the diagnostic and prognostic values of procalcitonin (PCT) to predict bacterial infection in SICU patients. Methods: We retrospectively analyzed the 2-year (2013 and 2014) records of 342 adult SICU cases with suspected bacterial infection in SICU of Hualien Tzu Chi Hospital. The past histories, the first infection-related parameters when SICU admission, culture results, infection-related laboratory examinations, and outcomes were collected. Results: Median of PCT level in patients with negative and any positive culture was 0.84 (interquartile range [IQR] 0.18–6.21) and 2.27 (IQR 0.54–9.93) ng/ml, respectively. Infection from blood, urine, and skin/soft tissue elicited significantly higher PCT levels. PCT in receiver operating characteristic (ROC) curve demonstrated the most accurate to predict bacterial infection (area under the ROC curve [AUC]: 0.61; 95% confidence interval [CI]: 0.54–0.63) and bacteremia (AUC: 0.73; 95% CI: 0.66–0.80) compared to white blood cell count, ratio of neutrophils, and neutrophil-to-lymphocyte count ratio (NLCR). Significantly higher PCT levels (4.12 ng/ml, 1.12–19.99; median, IQR) were observed in mortality cases. Higher PCT levels were significantly accompanied with higher NLCR, as well as higher incidence of leukopenia and bandemia. Using Kaplan–Meier analysis, significantly higher intrahospital mortality was observed in cases with above the cutoff PCT levels of 0.5 and 2 ng/ml cases, respectively. Conclusion: PCT is a relatively more useful tool to predict bacterial and particularly bloodstream infection compared to other infection-related parameters in routinely clinical practice. Initial PCT levels may be a prognostic factor of SICU patients with bacterial infection.

January-February 2019, 52(1):11-16
Background: Tailgut cysts are rare congenital lesions that are generally located in the retrorectal regions. We performed a cases series in Taiwan to compare with others. Materials and Methods: The demographics, clinical presentation, surgical management, pathological features, and long-term outcome of 14 patients of tailgut cysts diagnosed at Taipei Veterans General Hospital from 1989 to 2018 were reviewed. Results: In this series, 11 patients (78.6%) were female with the mean age of 46.7 (18–75) years. The majority of cases (83.3%) were symptomatic with variable manifestations. All patients received radiological examination and/or endoscopy. One case underwent biopsy before the therapy. Surgical methods included Kraske, transanal, abdominal, and combined approaches. Tailgut cysts were benign in ten patients (71.4%) and malignancy included mixed adenoneuroendocrine carcinoma, carcinoid tumor, and borderline mucinous tumor. No long-term adverse effect was reported. There was no recurrence of benign tailgut cysts during the median follow-up of 3 years. Conclusion: Tailgut cysts are uncommon and diagnosed predominantly in the middle-aged female. They can present with variable clinical manifestations, and diagnosis relies on image study. A routine preoperative biopsy is not indicated as it can be uninformative or false negative. Complete surgical excision is recommended even in asymptomatic cases for definite diagnosis and the possibility of malignant transformation. A variety of surgical approaches can achieve complete surgical removal and avoid recurrence if being planned ahead by image carefully.
