[Toxic dilatation of the colon].

Twelve patients (8 males and 4 females) with toxic dilatation of the colon in acute ulcerative colitis were reviewed, who required surgery between 1962 and 1974 at the Department of Surgery, University Kiel. This complication always occured during a relapsing exacerbation of known colitis. Nine patients died.

[Results of surgical treatment of Crohn's enterocolitis granulomatosa (author's transl)].

The possibilities of surgical treatment are outlined with reference to 45 patients with Crohn's enterocolitis granulomatosa. In 82% of the cases a large part of the colon is affected in addition to the terminal ileum, so that resections of the large intestine are necessary as a rule. In our patients the relapse rate after 3 years was 36%.

[Preoperative analysis of the gastric secretion as guidance for the operative procedure of peptic jejunal ulcers (author's transl)].

The development of a peptic jejunal ulcer after partial gastrectomy may result either from a technical deficiency of the anastomotic region, a seldom-occurring gastrin producing tumor, a displacement of the pyloric antrum into the alkaline milieu of the duodenal stump, an abnormally high vagus tone, or from too low a resection. In 17 out of 32 patients with a peptic jejunal ulcer preoperative gastric secretion analysis were performed during consecutive stimulation of the gastric secretion by gastrin-pentapeptide, histalog, and insulin-induced hypoglycemia. A high basal secretion, which could only be minimally stimulated by exogenous gastrin, required the operative revision of the duodenal stump.

[Free perforation of stomach and duodenum (author's transl)].

206 perforations of stomach or duodenal ulcers were treated by primary resection or simple suture between 1963 and 1972. The lethality of these two methods of treatment was compared with the age of the patients, the duration of symptoms, the length of time between perforation and surgery, and the localization of the perforated ulcer. Our analysis showed that, as a rule, primary resection is preferable, except in old age.
