Peptic ulcer surgery in the nineties: patient profile, immediate results and clinical findings.

The decreasing frequency of elective ulcer surgery and the persisting frequency of emergency surgery for peptic ulcer diseases has often been reported. The reason for the divergent epidemiological behaviour of the two subgroups of surgical candidates is not clear. The present cross-sectional, population-based analysis of patients undergoing peptic ulcer surgery evaluates the mode of preoperative therapy in elective and emergency cases.

Benign retroperitoneal schwannoma.

A rare case of benign retroperitoneal schwannoma in a 76-year-old man is reported. Ultrasound and computerized tomography disclosed two cystic retroperitoneal tumors sized 12 cm and 7 cm. The larger tumor was located anterior to psoas muscle and the smaller one was within the muscle.

Primary arterioenteric fistula between common iliac artery and ileum with massive bleeding.

Primary iliac artery aneurysms are rare, and a fistula to the terminal ileum with bleeding is very uncommon. A case with a primary massively bleeding iliaco-ileal fistula is described. In an emergency operation the common iliac artery was ligated and the fistula to the small bowel was resected.

Peptic ulcer surgery during the H2-receptor antagonist era: a population-based epidemiological study of ulcer surgery in Helsinki from 1972 to 1987.

To evaluate the effects of improvements in medical therapy on the incidence of, indications for and operative methods used in peptic ulcer surgery, all cases of primary peptic ulcer surgery among adults in the city of Helsinki in the years 1972, 1977, 1982 and 1987 were analysed. There was a total of 565 such cases in a population which consisted of 5.2 X 10(5) individuals in 1972 and 4.
