RESUMO
Serum gastrin levels were measured by radioimmunoassay in 62 patients with colorectal neoplasms (40 with adenomatous polyps and 22 with cancer) and 40 controls. Fasting serum gastrin in both the polyp (73.93 +/- 6.5 pg/ml) and the cancer (99 +/- 19.7 pg/ml) groups was significantly higher than those of the control group (42.65 +/- 2.2 pg/ml). These findings suggest that hypergastrinemia may be an etiologic factor in colorectal neoplasia.

Gallbladder perforation represents the most serious complication of cholecystitis. Rapid preoperative diagnosis is necessary because of the high morbidity and mortality associated with it. The authors present a case of gallbladder perforation in a 64-year-old man who had been on high doses of steroids. This case was diagnosed preoperatively by combined radiologic imaging methods.
