SELECTIVE INTESTINAL DECONTAMINATION IN PATIENTS WITH ACUTE DIVERTICULITIS COMPLICATED BY COVERED PERFORATION AS A WAY TO REDUCE THE NUMBER OF POSTOPERATIVE COMPLICATIONS

Abstract

The effect of selective perioperative intestinal decontamination in patients with acute sigmoid diverticulitis complicated by covered perforation on the number of postoperative complications was described. A prospective and partially retrospective study of the results of complex treatment of 196 patients with acute diverticulitis localized in the sigmoid colon, complicated by covered perforation, divided into group А - 66 patients with perioperative selective intestinal decontamination and group B -130 patients without decontamination. Rectal resection by open, laparoscopic and robot-assisted methods with the formation of primary colorectal anastomoses was performed in all cases. Of the 196 patients included in our study, 122 (62,2 %) underwent surgery without complications. Abdominal postoperative complications directly caused by surgical interventions and related, according to the classification of Clavien-Dindo surgical complications (C-D) to grades I, IIIb and IV, were noted in 9 (13,6 %) patients of group A and 36 (27,6 %) patients of group B, and extraabdominal (C-D I, IV), which included: pneumonia, acute renal failure, pyelonephritis, urosepsis, postoperative delirium and transient ischemic attack - in 8 (12,1 %) and 21 (16,1 %) patients of the corresponding groups. In group A, there was a significantly lower number of general abdominal and wound complications, as well as the total number of all postoperative complications (p = 0,03, p = 0,04 and p = 0,0111 respectively). There were no fatalities. The used scheme of oral antibiotic therapy, along with orthograde intestinal sanitation with osmolar solutions, significantly reduced the frequency of surgical and non-surgical complications.
