[Neoplasms of the small intestine].

Tumors of the small bowel comprise only 3--6% of all tumors of the intestine. The symptoms associated with tumors of the small bowel are not characteristic at the beginning. To establish an early diagnosis one must be "small bowel conscious". Mechanical intestinal obstruction, bleeding and perforation must be kept in mind for differential diagnosis.

[Endoscopic papillotomy (EPT) (author's transl)].

From August 1974 to December 1977 a total of 155 endoscopic papillotomies were performed. Endoscopic papillotomy (EPT) has proven to be an acceptable alternative to surgical reintervention at the biliary tree especially in aged and cholecystectomized patients where obstructive jaundice is caused by a concrement. The rate of all complications (9%) is comparatively low. In our own series 3 patients died after endoscopic papillotomy. EPT may be justified in jaundiced patients without previous cholecystectomy when there is a high risk for laparotomy. Preoperative drainage of massive hyperbilirubinaemia caused by a carcinoma of the papilla of Vater and treatment of the blind sack syndrome in cases of choledochoduodenostomy are further indications of this method. Late complications after EPT are not known until now.

[Clinical importance of Meckel's diverticulum].

Between 1966 und 1975 42 children and 46 adults were operated on Meckel's diverticulum. The diverticulum is explained as one of the possible disturbances during regression of ductus omphaloentericus. The appendicitis-like symptomatology correlates to the involvement of gastric and colonic mucosa as well as heterotopic exo- and endocrine tissue of the pancreas in the wall of the diverticulum. In 34% complications were due to inflammation, perforation, bleeding, intussusception, volvulus, gut-strangulation with ileus, ulcer, neoplasia or lesion by foreign bodies. 4 out of 88 patients died. Preoperative diagnostic fails in 75%, therefore in every case the distal gut should be inspected and every diverticulum should be resected.

[Insulitis and peracute diabetes mellitus (author's transl)].

We report on the case of a 10-month-old infant with Down's syndrome and acute insulin-dependent diabetes mellitus, who died of hyperosmolar diabetic coma 4 days after admission to the hospital in spite of intensive therapy. Characterizing this disease, a lymphocytic infiltration of the islets of Langerhanns with destruction of the islets was found. The specific localization of the inflammatory infiltrates as well as the histological findings correspond with experimental immune-insulitis in aminals, suggesting that immunological mechanisms play an essential pathogenic role. Virus etiology, diagnostic procedures, and therapeutic approaches are discussed.

[Isolated rupture of the interventricular septum after blunt chest trauma (author's transl)].

The mechanism, symptoms and treatment of traumatic ventricular septal defect are discussed on the basis of an own observation. To the best of our knowledge this is the first report of a rupture of the membranous septum, involving the portion between the left ventricle and the right atrium. An attempt is made to explain the mechanism of isolated traumatic ventricular septal rupture on the basis of embryological considerations. The patient died on the 11th postoperative circulatory status and inspite rather prompt diagnosis and operative treatment.
