Conservative methods of treatment were conducted for 110 patients. Naso-intestinal endoscopic intubation of the small intestine for decompression of the gastrointestinal tract was performed to 68 patients. The estimation of the risk group for the effectiveness of conservative measures in patients with adhesive peritoneum disease complicated by acute intestinal impairment, provides an objective choice of the type of treatment. The justification and amounts of conservative measures involving endoscopic naso-intestinal intubation (ENII) of the gastrointestinal tract were determined. The resolution period of the acute intestinal impairment affected by adhesive peritoneum disease in the small risk group was 9.8 ± 3.4 h; in the group of average risk – 18.6 ± 4.4 h; all high-risk patients should be urgently operated after short-term preoperative preparation. The analysis of clinical-anamnestic-instrumental data following by the determination of the effectiveness of conservative measures has allowed to reduce the lethality of patients with adhesive peritoneum disease complicated by acute intestinal impairment to 1.8%.
