[Re-operations after formerly performed suturing of the "silent" perforative duodenal ulcer].

After the "silent" perforative duodenal ulcer closure the gap till the complications would occur, which need reoperation, by two times more than such period of time in patients with typical ulcer anamnesis, preceding the perforation. The reoperation causes are the recurrence (in 50.6% of observations), newly occurred ulcer (in 26.

The experience with treatment of 454 patients with the ulcer disease recurrence which occurred after closure of a perforative duodenal ulcer is presented. Disease recurrence developed in 83.9% of the patients, and was complicated in 54.

[The use of low-intensity laser irradiation in the immediate postoperative period in patients with gastroduodenal ulcer].

In patients with an ulcer of the stomach and duodenum at the immediate postoperative period in the complex of treatment, the low intensity laser irradiation of the anastomosis (after gastric resection) and ulcer (after the organ-preserving operations) according to the developed method by means of the modified LG-75 apparatus was used. The use of a helium-neon laser contributed to development of the severe form of anastomositis and subsequent gastrostasis. In study of gastric secretion, no considerable changes in acid formation were revealed.
