[Relaparotomy: the indications, procedure and results].

Based on an analysis of 284 observations amounting to 1.8% of the total number of operations on organs of the abdominal cavity the authors give more exact indications to early relaparotomy and to more optimal methods to eliminate complications appearing after primary operations. They recommend wider use of additional methods of diagnosis of postoperative complications which will result in less lethality after relaparotomies.

[Vagotomy combined with drainage in pyloroduodenal stenosis caused by duodenal ulcer].

Various vagotomies with draining operations on the stomach were performed on 56 patients with ulcerous pylorostenosis. The authors recommend a wide use of organ-preserving operations for pyloroduodenal stenosis.
