BACKGROUNDLiver abscess is a serious complication following transcatheter arterial chemoembolization (TACE). Much attention has been paid to this condition as it may interfere with the treatment process and result in a poor prognosis of the patient. This study aimed to analyze the causes of liver abscess, a complication, after TACE for hepatic tumors and to summarize management approaches.

METHODSFrom June 2012 to June 2014, of 1480 consecutive patients who underwent TACE at our hospital, five patients developed liver abscess after TACE procedures for hepatic tumors. Of the five patients, each receiving conventional TACE, one underwent three sessions, two underwent two sessions, and the remaining two underwent one session of TACE. Demographic and clinical characteristics, together with management approaches and prognosis, were collected through a review of medical records.

RESULTSThese five patients were confirmed to have post-TACE liver abscess through clinical manifestations, laboratory, and imaging tests. After percutaneous drainage and anti-inflammatory treatments, the symptoms present in four patients with liver abscess significantly improved as evidenced by shrinkage or disappearance of the abscess cavity, and the patients recovered completely after sufficient drainage. The remaining patient experienced recurrent symptoms and abdominal abscess, achieved no significant improvement after treatment, and eventually died of severe infection and multiple organ failures.

CONCLUSIONSTACE must be implemented with extreme caution to avoid liver abscess. An effective management relies on an early diagnosis, prompt use of sufficient doses of appropriate antibiotics, and active implementation of abscess incision, drainage, and aspiration.

Idiopathic cecal ulcer is a rare disease entity of unknown cause diagnosed by ruling out other known causes of cecal ulceration. The most common complication of an idiopathic cecal ulcer is bleeding; perforation, peritonitis, abscess, and stricture formation have been noted. The authors treated a 53-year-old woman who presented with fever and intermittent right upper quadrant abdominal pain. Multiple pyogenic liver abscess and a solitary cecal ulcer were diagnosed by radiologic, endoscopic, and pathologic examination, followed by laparoscopic cecectomy. After extensive study, we concluded that this patient's liver abscesses were a complication of the idiopathic cecal ulcer. Herein, we report a case of multiple pyogenic liver abscess caused by microperforation of idiopathic cecal ulcer.

Klebsiella pneumoniae liver abscess has a tendency to spread to distant sites early in the course of disease and to involve multiple organs synchronously. A 59-year-old male was admitted because of liver abscess accompanied by fever and abdominal pain. The patient underwent percutaneous catheter drainage and received intravenous antibiotics. Symptom relief was achieved after the treatment as well as marked reduction in the size of the abscess. Despite proper treatment of the liver abscess, however, patient developed multiple metastatic infections in a non-concurrent manner: left and right endophthalmitis, psoas abscess, and infectious spondylitis at 5, 23, 30 and 65 days after initial manifestations of liver abscess, respectively. Each infectious episode followed one another after resolution of the former one. For each episode of metastatic infections, the patient promptly underwent treatment with systemic and local antibiotics, interventional abscess drainage, and surgical treatments as needed. The patient fully recovered without sequelae after the use of intravenous antibiotics for an extended period of time. Herein, we report a case of K. pneumoniae liver abscess complicated with delayed-onset multiple metastatic infections.

Necrotizing pancreatitis is one of the rare complications of transcatheter arterial chemoembolization (TACE). Necrotizing pancreatitis after TACE may result from the development of ischemia caused by regurgitation of embolic materials into the vessels supplying the pancreas. We report a case of post-TACE necrotizing pancreatitis with abscess formation in a patient with hepatocellular carcinoma. The patient had suffered hepatic artery injury due to repetitive TACE; during his 25th TACE procedure he had submitted to selective catheterization of the feeding vessel from the dorsal pancreatic artery with a cytotoxic agent and Gelfoam particles. The patient complained of abdominal pain after the TACE procedure, and a CT scan led to a diagnosis of necrotizing pancreatitis with abscess formation. The pancreatic abscess progressed despite general management of the pancreatitis, including antibiotics. Percutaneous catheter drainage was performed, and the symptoms of the patient improved.

Amoebic liver abscess is a common disease, especially in endemic areas, but it is a rare cause of inferior vena cava (IVC) obstruction, with only a few cases appearing in the literature. We report three cases of amoebic liver abscess complicated with obstruction of the IVC and which responded to conservative treatment or radiological intervention.

Fusobacteria are anaerobic gram-negative, non-spore forming bacilli found in normal flora of the oral cavity, urogenital tract, and gastrointestinal tract. Fusobacterium nucleatum has been seldom reported as a cause of liver abscess, particularly in immunocompetent hosts. A 55-year-old man with frequent periodontal disease visited our hospital with intermittent fever and headache for 2 months. Abdominal CT scan revealed an 8.2x6 cm mass in the right hepatic lobe with central low density. Abscess culture revealed F. nucleatum as the causative organism. Percutaneous abscess drainage and intravenous administration of antibiotics for 4 weeks improved symptoms and decreased the abscess size. We report a rare case of liver abscess due to F. nucleatum in an immunocompetent man with periodontal disease.

Hepatocellular carcinoma (HCC) is one of the most common malignant neoplasms occuring worldwide. Although surgical resection still remains the treatment of choice for HCC, radiofrequency ablation (RFA) has emerged as reliable alternatives to resection. It is less invasive and can be repeated after short intervals for sequential ablation in case of multiple lesions. The most common complication of RFA is liver abscess, and bile duct injury such as bile duct stricture has been reported. This is a case report of a rare complication of abscesso-colonic fistula after RFA for HCC. The case was treated by percutaneous abscess drainage and antibiotics and occlusion of abscesso-colonic fistula with n-butyl-2-cyanoacrylate embolization.

Intrahepatic abscess is an unusual complication of peptic ulcer disease. We present a case of gastric cancer in which the ulcer penetrated into the left lobe of liver with subsequent abscess and fistula formation. Esophagogastroduodenoscopy confirmed ulcers and a fistula opening in the antrum. Abdominal computed tomogram showed a subcapsular liver abscess adjacent to the gastric antrum. Subtotal gastrectomy with curettage of the fistulous tract was performed. The final diagnosis was the signet ring cell gastric carcinoma complicating subcapsular liver abscess. To our knowledge, this is the first reported case in Korea.

Gastrointestinal stromal tumor (GIST) is an uncommon mesenchymal tumor of the gastrointestinal tract and is generally located in the stomach and small intestine. They usually present with abdominal pain, gastrointestinal bleeding, and palpable mass. Some patients present with rare symptoms that are more common in malignant GIST. Malignant GIST combined with a liver abscess has not been reported yet in the literatures. We report a case of 67-year-old woman who suffered from liver abscess combined by malignant GIST with central necrosis and fistula in the ileum. She complained of fever, chills, and abdominal pain. Abdominal CT scan showed huge liver abscess and ileal mass with air pocket. Small bowel series showed contrast material filling into the ileal GIST mass. An operation was performed and the final diagnosis was malignant GIST of the ileum with invasion into the sigmoid colon and urinary bladder.
