Rationale. To date, the issues of early diagnosis and surgical treatment of patients with injuries to the retroperitoneal duodenum have not been resolved. Due to late diagnosis, the development of retroperitonitis in a short time after injury, the frequency of postoperative complications reaches 20% - 32%, and mortality - up to 18% - 27%.Purpose of the study. Improving the results of treatment of patients with damages to the retroperitoneal part of the duodenum.Methods. The results of treatment of 54 patients with a rupture of the retroperitoneal part of the duodenum are presented. In the study of patients with suspected damage to the retroperitoneal part of the intestine used ultrasound, EUS, FGDS and MSCT with intraluminal contrastResults. 28 victims were sutured by a duodenal defect and cholecystostomy. In these patients, the patient was disconnected by a flashing apparatus, and a gastroenteroanastomosis was formed. The failure of the duodenal sutures developed in 10 (35.7%), 8 (28.6%) victims died26 victims, after mobilization of the intestine by Kocher, were performed excision of the edges of the rupture of the intestinal wall and the formation of the side-to-side duodenojejunostomy with the Ruian loop of the jejunum off. The postoperative period was smooth in 20 victims. 2 patients with concomitant injuries of the liver, spleen, skeleton bones died 2 and 4 days after the operation due to severe blood loss and shock. In the postoperative period, 4 patients on the 5th and 6th day developed micrononextensity of the seams of duodenojejunostomy. Both patients were treated conservatively and were discharged.

Improving the results of treatment of patients with Burhave syndrome and its complications through the use of minimally invasive and traditional technologies.MATERIAL AND METHODS. The results of treatment of 35 patients with Burhave syndrome and its complications are presented. RESULTS. The article is devoted to the diagnosis and treatment of patients with spontaneous rupture of the esophagus. The possibilities of modern methods of diagnosis and minimally invasive technologies in the treatment of patients with Bourhave’s syndrome in relation to the severity of the patient's comorbidity index have been studied. Traditional operations were performed on 27, minimally invasive interventions - 8 patients. After traditional operations and suturing the rupture of the esophagus wall in 26 patients, the failure of the sutures in the postoperative period for 4-6 days was observed in 8 (30.8%) patients. Various complications in the postoperative period were observed in all patients. 11 patients died (31.4%)
