14 cases of carcinoid tumors over a period of 16 years are reported. There are 7 carcinoids of the vermiforme appendix, 3 of the small bowel, 1 of the rectum, and 2 carcinoids of the bronchus. No carcinoid syndrom was observed. Three patients with carcinoid tumors, localized in the small intestine died immediately post operationem. All others are still alife and followed up between 6 month and 13 years, are free of symptoms or rezidives. Poor prognosis of the carcinoids of the small intestine seems to depend on late diagnosis, complications already occured at the moment of operation, and advanced age of these patients. Different malignance is not considered to be an important factor of prognosis.

Primary mesenteric venous thrombosis seldom occurs in young women. As a complication of oral contraceptives it is uncommon as well. Based on an own observation (39 year old female patient) pathogenesis and problems in diagnosis of this aspect of thrombosis are discussed. Involvement of the veins being segmentary and peripheral, small bowel resection is the effective treatment.

Septic or toxic shock is a life threatening complication after abdominal operations. The etiologic analysis of our 102 patients showed the following conditions: 1. diseases, which have already preoperatively a high incidence of septic complications, 2. sepsis developing after primary aseptic diseases, 3. septis without any etiologic connection to the primary disease or operation. An initial standarised intensive therapy must start before any irreversible organ damage may occur. First aim of all surgical measures is the eradication of the source of infection. Early relaparotomy is the only possibility for correction of intraoperativ technical defects. Only by longstanding combination of intensive personal and technical support prognosis of septic shock after abdominal operations can be improved.
