This study will compare results of different intestinal decompression techniques in patients with small bowel obstruction.
Taking into account the large number of different variations of intestinal decompression methods, a comparative analysis will be carried out based on one comparison group (I) and three main ones (IA-B). The comparison criterion will be a group of patients with nasogastric drainage as the only method of the gastrointestinal tract decompression during surgery and in the postoperative period. In the main groups more active methods of intestinal decompression will be performed, including drainage of the initial parts of the small intestine or total intubation, both single-stage intraoperative and its extended version
Adult patients with benign forms of acute small intestinal obstruction and indications for the small intestine intubation: dilation of the the small intestine lumen above the level of a mechanical obstacle to 3.0 cm in diameter or more or the presence of intestinal paresis with the development of edema and microcirculatory disorders in intestinal wall.
Exclusion Criteria:
Nasogastric intubation only will be the only method of intestinal decompression both intra- and postoperatively.
Device: Intraoperative intestinal decompression
Intraoperative intestinal decompression will be performed by placing the tube behind the ligament of Treitz and expressing the contents in the proximal direction or by total nasointestinal intubation with subsequent intraopertional tube withdrawal. Postoperative decompression will consist of the tube behind the ligament of Treitz.
Device: Intraoperative intestinal decompression
Total intraoperative intubation of the small intestine followed by replacement with a nasogastric tube.
Device: Intraoperative intestinal decompression
Total intraoperative intubation of the small intestine with a long tube, which will persist in the postoperative period
Device: Intraoperative intestinal decompression
Insertion the tubes of various lengths (nasogastral, short and long nasointestinal) into the gastrointestinal tract during operations in patients with acute small intestinal obstruction
30-day postoperative mortality
Number of patients, died during 30 days after the operation
Time frame: 30 days after operation
Postoperative complications
Postoperative complications, defined according Clavien-Dindo classification
Time frame: 30 days after operation
