BACKGROUND Rupture of a pyogenic liver abscess is rare but serious complication. In patients after pancreatoduodenectomy, there are some conditions causing the development of liver abscesses (e.g., chronic reflux-cholangitis, efferent jejunal loop stasis, stenosis of the biliary anastomosis, and pancreatogenic diabetes). However, the number of published cases of liver abscess after pancreatoduodenectomy is small. CASE REPORT A 42-year-old male was admitted with severe abdominal pain, fever, and jaundice. Nineteen years previously, he had undergone pancreatoduodenectomy and cholecystectomy for chronic pancreatitis with obstructive jaundice. Two years later, diabetes mellitus was diagnosed, with subsequent insulin treatment. At admission, symptoms of peritonitis were present. Plain abdominal radiography showed free gas under the right hemidiaphragm and heterogeneous liver shade with small gas-fluid levels. The rupture of a liver abscess was suspected. Laparotomy with adhesiolysis, debridement of the liver abscess cavity, and abdominal drainage were performed. The postoperative period was complicated by sepsis, right lower lobe pneumonia, and two-sided pleural effusions, on the background of insulin-dependent diabetes and malnutrition. The patient was discharged on the 40th day and the subdiaphragmatic drains were removed on the 114th day. Sixteen months after surgery, the patient's condition was satisfactory. Magnetic resonance imaging and echography showed the absence of biliary hypertension. The liver tissue had healed completely. CONCLUSIONS A unique case of ruptured liver abscess after pancreatoduodenectomy is presented. To the best of our knowledge, this is the first published case with such a long time interval (19 years) between pancreatoduodenectomy and the formation of a pyogenic liver abscess.

Trepan-biopsy material from patients with diseases of the liver is good for a histological investigation but in 2 out of 3 cases due to its structure, and in all cases--for a cytological investigation. Using these two methods of investigation eliminates objective causes of discrepancy between their results and increases the informative value of the pathomorphological diagnostics of diseases of the liver as a whole.
