[The course and surgical treatment of gastroduodenal ulcer in patients with diabetes mellitus].

The work deals with the features of the course of gastric and duodenal ulcers in diabetes mellitus and the frequency and pattern of the complications. The authors recommend criteria for preparation for surgical treatment, methods for compensation of the disturbances of carbohydrate metabolism, and the methods of postoperative management of such patients.

[Use of a single-row suture in surgery of the gastrointestinal tract].

The authors show the results of experimental and clinical study of a single-row Pirogov-Mateshuk serous-muscular-subserous suture with the knots inside the lumen. It was demonstrated in experiments on 191 dogs that regeneration in the zone of anastomoses formed by a single-row suture is more perfect and occurs earlier than with the application of a double-row suture. Among 2,623 anastomoses formed on the esophagus, stomach, small intestine, colon, and rectum by means of a single-row suture, 1.

[The choice of the extent of the operation in patients with thyroid cancer].

The results of 676 radical operations for thyroid cancer are discussed. The choice of procedure was determined by tumor histology which was assessed using trephine biopsy. Extracapsular hemithyroidectomy was the basic procedure (420 out of 676 cases) used for the treatment of well-differentiated thyroid cancer affecting one lobe only.

[Psychological aspects of relaparotomy].

The authors analyse the importance of the psychological barrier in the choice of the method of treatment in performing relaparotomy. Proceeding from the fact that the surgeon's psychological barrier is an objective factor aggravating the results of management of postoperative complications, the authors suggest that the indications for relaparotomy should be considered collectively. They believe that the second operation should be carried out by another, more experienced surgeon of the department.

[Pathogenetic treatment of chronic paraproctitis].

Operations were performed on 865 patients for pararectal fistulas. The fistulas occurred after injury in 18 patients, histological examination revealed fistulous form of Crohn's disease in 14 patients, 12 patients had tuberculous paraproctitis. The late-term results of surgical treatment of chronic paraproctitis were studied in 560 patients according to the presence of concomitant hemorrhoids.

[Relaparotomy after emergency surgical interventions].

Relaparotomy was conducted 251 times on 210 emergency surgical patients. Diffuse and localized circumscribed peritonitis were the main causes of relaparotomy (70.5%).

[Surgical tactics in ulcerous pyloroduodenal stenosis].

The authors generalize their experience in the treatment of 528 patients with ulcerous pyloroduodenal stenosis, who accounted for 19.3% of all patients who were operated on and for 29.8% of those with complicated forms of peptic ulcer.

[Relaparotomy after operations on the rectum and colon].

During 15 years 1663 intraabdominal operations on the rectum and colon were performed, relaparotomy resulting from the complications was fulfilled in 134 patients (8%). The main indication for relaparotomy was peritonitis (57 patients). Its sources were: incompetence of the colonic anastomosis suture, technical errors during the first operation, opening of the abscess into the abdominal cavity.

[Simultaneous surgery in gastroduodenal ulcer].

The results of 96 simultaneous operations for peptic ulcer are discussed. The indications for their performance are substantiated and the principles of their conduction in various diseases aggravating one another are determined. The low incidence of postoperative complications (4.

[Repeat operations after surgical interventions in perforated gastroduodenal ulcers].

Indications to reoperations and conditions of performing them are analyzed on the basis of an experience with 188 reoperations. Principles of choice of the method of reoperations are given which depend on the defects of the primary operations.
