[Surgical diseases in patients under long-time dialysis and after kidney transplantation (author's transl)].

In uremic patients under long-time dialysis and after kidney transplantation surgical diseases with severe complications may occur, such as gastro-duodenal ulcers, inflammatory and ischaemic diseases of the colon, acute pancreatitis, intestinal obstruction. Most of the complications have only poor symptoms. If complications are suspected, an "aggressive diagnostic regimen" is mandatory. The incidence of cancer is higher in these patients. Complications can be diminished by prophylactic operations, such as gastric resection in gastro-duodenal ulcer. A restriction in elective and emergency operations has no longer a place in these patients.
