Pancreatojejunal sutural insufficiency occurring after pancreatoduodenectomy and countermeasures are discussed. In the Department of Surgery at Kurume University School of Medicine, 318 patients underwent pancreatoduodenectomies. The present study includes 15 of these patients, all of whom had pancreatojejunal sutural insufficiency. The frequency of sutural insufficiency was 4.7%. Five patients had bile duct cancer, 5 had cancer of the papilla of Vater, 2 had a carcinoma of the pancreatic head, 1 each had gallbladder cancer, chronic pancreatitis, and papillitis. Six (40%) of the 15 patients died during hospitalization. The presence or absence of sutural insufficiency was confirmed mainly by radiography and determining the properties and amylase levels of the drainage fluid. There was no significant difference due to the method of anastomosis. End-to-side anastomosis had a rate of 5 (5.9%) of 85 patients, while end-to-end had 10 (4.3%) of 233 patients. The sutural insufficiency was manifested as a major leakage in 6 patients and a minor leakage in 9. The degree of lymph node dissection was D0 in 6.1%, D1 in 1.4%, D2 in 4.8% and D3 in 10.8%, with a high incidence of sutural insufficiency in D3 patients. The pancreatic duct diameter was smaller than 4 mm in 10, 5-7 mm in 4 and over 8 mm in 1 patient. The intraoperative pancreatic findings were a soft pancreas in 8, slightly hard in 3, and hard in 4 patients. Fibrosis of the pancreas was normal to slight in 11 and moderate in 4 patients. Drainage by relaparotomy was performed in 4 of the 6 patients with major leakages to control sutural insufficiency, and the other 2 underwent continuous aspiration with an intraperitoneal drain inserted during the operation. The 9 patients with minor leakage underwent conservative treatment including continuous aspiration via an intraperitoneal drain inserted during surgery, fasting, intravenous hyperalimentation, and antibiotic administration. All of the patients with major leakage died from an associated occurrence of hepatic insufficiency, renal insufficiency, intraperitoneal hemorrhage or diffuse peritonitis during hospitalization. However, 8 of the 9 patients with minor leakage had some healing, and the 1 remaining patient developed a pancreatic fistula. The frequency of pancreatojejunal sutural insufficiency was high in patients with minimal pancreatic fibrosis, with soft pancreatic tissue without dilatation of the pancreatic duct, and with relatively good pancreatic function.

A 51-year-old man had repeated admissions and discharges from the hospital for alcohol dependence and alcoholic hepatitis. Thereafter, with a diagnosis of chronic pancreatitis, he was examined on an outpatient basis. He presented with right hypochondriac pain as the chief complaint, and was admitted to the hospital because of a suspected acute exacerbation of chronic pancreatitis. Pyrexia and jaundice were present from about the 5th hospital day, and he was admitted to Kurume University Hospital with a diagnosis of obstructive icterus. Percutaneous transhepatic biliary tract drainage (PTBD) was immediately performed. A roentgenogram revealed moderate dilatation of the extrahepatic bile ducts and stricture of the intrapancreatic common bile duct. No calculi were observed in the gallbladder or bile ducts by ultrasonography of the abdominal region. The main pancreatic duct was dilated to 10 mm, and a strong echo, probably a calculus, was observed in the main pancreatic duct. Pancreatoduodenectomy was performed with a diagnosis of stricture of the common bile duct due to chronic pancreatitis with a pancreatic stone. Examination of the excised specimens revealed a rigid pancreatic head; and when the common bile duct was incised, no stricture was observed. A milk-white calculus about 10 mm in diameter was observed in the common channel of the lower portion of the common bile duct. The orifice of the pancreatic duct was also observed at the same site. The common channel was about 20 mm long, and malfusion of the pancreatobiliary ducts was observed. The obstructive icterus was due to an impaction of the pancreatic stone at the confluence of the pancreatobiliary ducts. The calculus was composed of calcium carbonate, and the histopathological findings in the pancreas showed chronic pancreatitis.

Adriamycin-Lipiodol emulsion (ADR-LIP) was injected, percutaneously via a 20 gauge needle with ultrasonographic guidance, as part of the treatment of 4 patients with relatively small hepatocellular carcinoma (HCC). Lymph vessels extending from the tumor nodule to the abdominal lymph nodes were imaged immediately after the injection in 3 patients. Subsequent plain films of the abdomen and abdominal computed tomography demonstrated stagnant collections of ADR-LIP in the abdominal lymph nodes. Histologic examination of lymph nodes removed during partial hepatectomy or at autopsy in these cases revealed many large and small fat droplets, thought to be Lipiodol, as well as macrophages containing phagocytized lipid. Although lymphatic metastasis occur in HCC, these findings suggest that lymphatics may exist in HCC tissue during the relatively early stages of tumor growth.
