We investigated early postoperative morbidity, mortality, and long-term outcomes in patients with liver cirrhosis (LC) who had undergone curative surgery for gastric cancer. The medical records of patients with LC who had undergone radical gastrectomy for gastric adenocarcinoma between January 1996 and September 2006 were retrospectively reviewed. A total of 57 patients were enrolled in this study. Forty-six patients (81%) were classified into Child's class A. In 22 patients (39%) postoperative complications developed, the most common being ascites (23%), followed by wound infection and hepatic encephalopathy. Postoperative ascites occurred more frequently in patients with Child's class B or C than in those with class A (63.6% vs 13%, P = 0.001). Massive ascites developed in 4 patients, 3 of whom had Child's class B and underwent D2 lymph node (LN) dissection, and 1 of whom had Child's class C and a D1 LN dissection. Postoperative mortality occurred in 5 patients (9%), with a significantly higher mortality rate for patients with Child's class B or C than for those with class A (27.2% vs 4.3%, P = 0.045). With a median follow-up of 32 months, the estimated 5-year survival rate for all patients was 54%. Regardless of the tumor depth, overall survival was longer for patients with Child's class A than for those with Child's class B or C. These results demonstrated that radical gastrectomy with extended LN dissection is feasible in patients with compensated LC. For patients with moderate to severe hepatic dysfunction, however, D1 or less extensive LN dissection may be the more reasonable surgical procedure.

Primary duodenal mucosa associated lymphoid tissue (MALT) lymphoma is very rare, and little is known about its clinical course or effective treatment. We describe a case of primary duodenal MALT lymphoma that was resistant to Helicobacter pylori (H. pylori) eradication and regressed after chemotherapy with cyclophosphamide, vincristine, and prednisolone (CVP). A 71-year-old woman was referred to our department because of epigastric pain and dyspepsia. Gastroduodenoscopy revealed an irregular mucosal nodular lesion with ulceration extending from the bulb to the second portion of the duodenum. Histopathological examination of a biopsy specimen disclosed low-grade MALT lymphoma composed of atypical lymphoid cells with lymphoepithelial lesion. Abdominal CT scans revealed 0.5 to 1.5 cm lymph nodes in the peritoneal cavity, suggestive of lymph node metastasis. We successfully eradicated H. pylori but did not see signs of remission. We administered systemic CVP chemotherapy every 3 weeks. After 6 courses of CVP, the patient achieved complete remission and was followed up without recurrence for about a year.

Acute symptomatic portal vein obstruction related to biliary stenting is an extremely rare but life-threatening complication. This usually occurs in patients with either tumor invasion into the portal vein or pre-existing portal vein thrombus. Therefore, the portal vein should be carefully evaluated before placing a biliary metallic stent in such patients. We describe a case of acute portal vein obstruction after placing metallic biliary stents in a patient with a periductal-infiltrating type of hilar cholangiocarcinoma. (Gut and Liver 2008;2: 47-50)
