The cases of gastric stump cancer recorded at the III-rd Surgical Clinic of Iaoi during the last 5 years are analysed. Based upon the personal experience and data in the literature 7 cases are discussed. Out of the 7 cases, in 3 an initial resection for gastric ulcer and in 4 for duodenal ulcer was performed 17-40 years previously (with an average of 26 years). All the patients presented Bilroth II anastomoses. The diagnosis was determined by radiological, endoscopic and endobioptic examinations after a mean interval of 10 month since the occurence of the clinical symptoms. The site of the lesion was the following: in 3 cases on the anastomosis line and in 4 on the reminder of the stump. Out of the 7 cases, 5 were operable and in 4 the resection was completed. Two days post-operatively a death was recorded. The conclusions of this paper insist upon the fact that the occurance of the tumor on the gastric resection stump mainly depends on the initial lesion (gastric lesion) and less on the type of anastomosis. The long-term surveillance of the gastric resection patients is thus essential.
