A case of rectal carcinoid tumor with metastases to multiple organs is presented. On the basis of this clinical observation, some characteristics of rectal carcinoid tumours are discussed.
We report on two patients. The first patient is a 62-year-old female patient who had cholecystectomy in 1970, and in whom two small bile duct stones were removed after endoscopic sphincterotomy in 1987. Within two months of this procedure, she developed three episodes of documented acute pancreatitis. The other patient, a 58-year-old female, developed acute pancreatitis three months after an endoscopic sphincterotomy for stones in the common bile duct. In both patients, ERCP revealed a cicatricial stenosis of the common bile duct and the pancreatic duct. The condition was resolved by repeat sphincterotomy. The first patient needed repeated endoscopic insertion of bilioduodenal endoprostheses and an endoprosthesis in the pancreatic duct. It is interesting to note that, in contrast to surgical reports, very few postpapillotomy stenoses are reported by endoscopists.
Eighty-four patients with healed duodenal ulcers were treated for 1 year with pirenzepine, 50 mg twice daily, or placebo in this double-blind, randomized, multicenter trial. Clinical follow-up and endoscopy were performed before and after 3, 6, and 12 months of treatment. Endoscopy was also carried out whenever symptoms compatible with ulcer recurrence were present for more than 2 days. Both groups were well matched for age, sex, duration of peptic ulcer disease, and smoking habits. There were 21 drop-outs due to lack of compliance. Therefore, 32 patients treated with pirenzepine and 31 with placebo were included in the analysis. Expressed in cumulative percentage of recurrence, with pirenzepine, 28% of the patients had a relapse at 3 months, 41% at 6 months, and 53% at 12 months; with placebo, the recurrence rates were 58% at 3 months, 68% at 6 months, and 71% at 12 months. The mean success time at 1 year is also longer for pirenzepine (7.38 months) than for placebo (5.52 months). These differences are significantly in favor of pirenzepine (p less than 0.05). Both treatments were well tolerated. Dry mouth was more frequently observed with pirenzepine (14 versus 5 patients). We conclude that pirenzepine, 50 mg twice daily, significantly reduces the relapse rate of duodenal ulcers during a 1-year maintenance treatment.

Although it is not uncommon to encounter a Mecklel's diverticulum in a patient with Crohn's disease, the involvement of this diverticulum by Crohn's disease is less common. A well performed radiological small intestinal study strongly suggests the diagnosis, which is definite after histologic examination of the reported.
