1%). 12 patients (4.7%) underwent gastro-duodenal resection and 6 patients (2.4%) received conservative treatment. The remaining patients underwent alternative procedures. Of the 145 patients with small bowel perforations, 98 underwent open small bowel resection (85.2%) and 3 (2%) underwent laparoscopic small bowel resection. 28 patients (19.3%) were treated by stoma. Among the 115 patients with colonic non-diverticular perforation, 42 (36.5%) underwent Hartmann resection, 26 (22.6%) underwent open resection with anastomosis and without stoma protection, and 26 underwent open resection with stoma protection (22.6%). 170 cases (8.9%) were attributable to post-operative
infections. Source control was successfully implemented for 1,735 patients (91.4%). Microbiology Intraperitoneal
specimens were collected BVD-523 in vitro from 1,190 patients (62.7%). These specimens Selleck PD 332991 were obtained from 977 of the 1,645 patients presenting with community-acquired intra-abdominal infections (59.4%). Intraperitoneal specimens were collected from 213 (84.2%) of the remaining 253 patients with nosocomial intra-abdominal infections. The aerobic bacteria identified in intraoperative samples are reported In Table 4, 5.
