[Hemorrhage into the digestive tract as a cause of death in patients after kidney transplantation]. / Krvácení do zazívacího traktu jako prícina úmrtí u nemocných po transplantaci ledvin.

ABSTRACT

The authors investigated the prevalence, cause and possible prevention of haemorrhage into the gastrointestinal tract in 218 patients after transplantation of the kidney (TK). 1. Haemorrhage into the gastrointestinal tract after TK occurred in 32 patients incl. 53.1% who died. In the total mortality after TK haemorrhage into the gastrointestinal tract account for 15.7%. 2. The danger of haemorrhage into the gastrointestinal tract is increased in particular in the early postoperative period (within one month after transplantation of the kidney), during acute rejection with declining function of the graft, in infectious complications, after graftectomy, in preexisting peptic ulcers. 3. The most frequent cause of haemorrhage were duodenal ulcers. The authors elaborated a system of preventive provisions which involve a) medicamentous prophylaxis by administration of H2 blockers and antacids not only at the time of transplantation of the kidney and during the early postoperative period but also when there is an increased risk, b) detailed gastroenterological examination before transplantation of the kidney, c) in case of relapsing peptic ulceration in the case-history or haemorrhage into the gastrointestinal tract, subject patients on the waiting list for transplantation of the kidneys during the dialyzation period to proximal gastric vagotomy, or so-called highly selective vagotomy.
