Liver abscess caused by foreign-body penetration of the alimentary tract is rare. Preoperative diagnosis is difficult as patients are often unaware of the foreign-body ingestion and the unusual characteristic is often being paucisymptomatic until secondary complications occur. We report a patient with fishbone-related liver abscess. Preoperative demonstration of a hyperdense, linear lesion was performed by computed tomography. He was treated successfully after removal of the foreign body and drainage of the abscess.

| Introduction|| |
Perforation of the gastrointestinal tract caused by ingested foreign bodies is uncommon, and consequent development into liver abscess is even rarer.,,
Chong et al. reviewed the literature for cases of liver abscess secondary to foreign-body penetration. They searched the PubMed database for English literature from 1955 to 2013 using the keywords “liver abscess,” “hepatic abscess,” and “foreign body.” Only 88 patients were reported in the literature.
We report a male patient with fishbone-related liver abscess. He was treated successfully after diagnosis by computed tomography (CT) and prompt surgery.
| Case Report|| |
A 57-year-old male presented to the emergency department with right upper abdominal pain accompanied by fever noted for 3 days. The patient had been admitted to another hospital 2 weeks ago for similar complaints. He had received upper gastrointestinal endoscopy, and only shallow gastric ulcer was noted then. The abdominal ultrasound was also performed without obvious abnormality found. He was discharged 4 days later as his symptoms improved after medical treatment with the diagnosis and acute gastroenteritis and peptic ulcer. However, recurrent right upper abdominal pain, fever, and chills with anorexia were noted this time. His vital signs were within normal limits except fever up to 38.5°C noted. The abdomen was soft to palpation yet mildly tender in the right upper quadrant.
The laboratory data included white blood cell 12780/μL (neutrophils: 75.8%), glutamic oxaloacetic transaminase/glutamate pyruvate transaminase: 60/100 U/L, and C-reactive protein: 12.56 mg/dl. No obvious abnormality was found in the plain abdominal X-ray. The abdominal ultrasound revealed a hypoechoic lesion in the left lobe liver. A contrast-enhanced CT scan demonstrated a multiloculated, hypodense mass measuring 4.6 cm at the left lobe of liver [Figure 1], and a linear, hyperdense object was found between the lesion and gallbladder [Figure 2]. The findings were consistent with a liver abscess consequent upon the presence of an intrahepatic foreign body. Then, laparotomy was arranged accordingly. Intraoperatively, mild thickening of the gallbladder wall with induration of hepatoduodenal ligament was noted. As the abscess located between the gallbladder and the liver, we performed cholecystectomy first to gain better access to the abscess. After cholecystectomy, the abscess cavity [Figure 3] was opened and a 3-cm linear foreign body, a fishbone, was retrieved from the abscess cavity [Figure 4]. No obvious perforation hole was found in the gastrointestinal tract nearby. Chronic cholecystitis and liver abscess were reported by a pathologist. Three microorganisms were isolated from the abscess cavity including Streptococcus constellatus, Streptococcus anginosus, and Peptostreptococcus asaccharolyticus. The blood culture was negative. The patient recovered smoothly after antibiotics treatment and was discharged under stable condition 10 days later. He had no recollection of ingesting the fishbone.

| Discussion|| |
The majority of ingested foreign bodies pass through the gastrointestinal tract smoothly within 1 week. However, gastrointestinal perforation as a result of foreign-body ingestion occurs in about 1% of these patients.
An ingested foreign body that perforated the gastrointestinal tract, migrated to the liver, and caused an abscess was first described by Lambert in 1898. In this index case, it was discovered upon autopsy that a pin had migrated through the stomach wall into liver, resulting in fatal hepatic abscess. Foreign bodies tend to lodge at the esophageal sphincters, pyloric canal, duodenum, ileocecal valve, and anus. Perforation of the gastrointestinal tract by foreign bodies can occur at any location, but the most common sites reported in the literature related to fishbone migration occurs through the stomach and the duodenum.,, Fishbone migration was also found to be the most common type of foreign body as the culprit in the development of liver abscesses, accounting for approximately 33% of cases. Due to its anatomical proximity with the stomach, the left lobe of the liver is the most frequent site where fishbones get impacted., Specific medical history related with perforation was suggestive in only a limited number of cases (7/60; 12%). In our case, no obvious evidence of perforation or scar could be identified during operation. It is presumed that the most possible location of fishbone penetration was via the stomach or duodenum. It is very likely that the previous epigastric pain episode is related to the penetration. Only 5% of patients with foreign-body abscesses recall the ingestion. It is difficult to establish the time until the onset of symptoms as patients rarely recall the episode of ingestion, and the migrating foreign body may remain silent until an abscess formation.
The clinical manifestations and laboratory tests of patients with liver abscess resulting from gastrointestinal perforation by foreign bodies are variable. Abdominal pain (77.3%) and fever (58%) were the most common, followed by vomiting (19.3%) and nausea (13.6%)., Most patients have nonspecific symptoms, which are the features of a general response against an intra-abdominal inflammatory process.,
Plain roentgenogram will sometimes highlight radiopaque foreign bodies. The ultrasonography and CT scans are useful in localizing the abscess and planning the surgical approach. CT scan is currently the gold standard for diagnosis for liver abscess related with fishbones, appearing as calcified linear structures., It is excellent in the detection of foreign bodies due to its high resolution and accuracy.,
A retained and unrecognized foreign body might lead to the recurrence of a liver abscess even after adequate drainage and antibiotic treatment. The cure rate without removal of the foreign body is low (9.5%). Successful treatment relies greatly on the removal of the nidus of infection and ranges from laparotomy, laparoscopy, to percutaneous and endoscopic removal via upper or lower gastrointestinal tract,,, along with adjunctive antibiotics. Surgical drainage of the abscess at the time of removal of the foreign body appears to be an adequate mean of infection source control (i.e. eradicating the focus of infection). Open surgery and abscess drainage remain the mainstay of the treatment for patients with foreign bodies lodged in the liver. Minimally invasive techniques such as interventional radiology or laparoscopic surgery should be reserved for carefully selected cases, where both sepsis control and foreign-body retrieval can be performed safely.,,,
Delayed diagnosis of liver abscess due to a foreign body may lead to poor therapeutic outcome. In the previous report, the mortality rate was 7.95% (7/88) with liver abscess due to fishbones.
The bacteriological presentations of foreign-body- and nonforeign-body-related pyogenic liver abscesses are different. Gram-negative aerobes, such as Klebsiella pneumonia and Escherichia More Details coli, constitute the majority of bacteria in nonforeign-body-related pyogenic liver abscess. On the contrary, normal oral flora, especially Streptococcus spp., are the most common pathogens of foreign-body-related pyogenic liver abscess., These organisms are commensal to the oral cavity and would be compatible with a swallowed foreign body with gastric penetration as the mechanism of infection.
Migrated foreign body-induced liver abscess is a specific entity and an increasingly recognized cause of treatment failure in liver abscess. Delayed diagnosis is a major concern despite extensive workup. The first step toward the correct diagnosis is increased awareness., This unusual condition should be kept in mind when dealing with cases of hepatic abscess or even sepsis of unknown origin. Early recognition and in-time removal of the foreign body are the key points for successful treatment.
