RESUMO
Objectives: Colorectal perforation is associated with high morbidity and mortality rates after surgery. We investigated various clinical features of patients who underwent emergency surgery for colorectal perforation and explored the risk factors for postoperative complications and hospital mortality. Methods: Data from 147 patients who underwent surgery for colorectal perforation were retrospectively reviewed. We investigated various clinical and operative factors, including inflammation-based prognostic scores (IBPSs), and evaluated the risk factors for postoperative complications and hospital mortality due to colorectal perforation. Results: Among 147 patients, the most frequent postoperative complication was wound infection (32 cases, 21.8%), followed by intra-abdominal abscesses (27 cases, 18.4%) after surgery for colorectal perforation. Time from onset to surgery ≥ 2 days (Hazard ratio [HR] = 2.810, p = 0.0383) and prognostic nutritional index (PNI) < 30 (HR = 3.190, p = 0.0488) were identified as risk factors for intra-abdominal abscess, while neutrophil-lymphocyte ratio (NLR) < 6.15 (HR = 5.020, p = 0.0009) was identified as a risk factor for wound infection. Time from onset to surgery ≥ 2 days (HR = 7.713, p = 0.0492), severe postoperative complications (Clavien-Dindo grade ≥ IIIa) (HR = 10.98, p = 0.0281), and platelet-lymphocyte ratio (PLR) < 144 (HR = 18.84, p = 0.0190) were independent predictive factors for hospital mortality. Conclusions: Time from onset to surgery and IBPSs such as PNI, NLR, and PLR, may be associated with postoperative complications and hospital mortality due to colorectal perforation.
RESUMO
INTRODUCTION: This study aimed to clarify the validity of laparoscopic surgery for lower gastrointestinal perforation by comparing the clinical outcomes of laparoscopic and open emergency surgery. METHODS: We reviewed the data of patients who underwent surgery for lower gastrointestinal perforation. Patients were categorized into two groups: the laparoscopic group who underwent laparoscopic surgery, and the open group who underwent laparotomy. Clinical and operative outcomes between the two groups were evaluated. RESULTS: A total of 219 patients were included in the study. There were 66 and 153 patients with small bowel and colorectal perforations, respectively. The median operative time in the laparoscopic group was shorter than that in the open group (126 min vs. 146 min, p = .049). The mean amount of intraoperative blood loss was significantly lower in the laparoscopic group (50.4 mL vs. 400.1 mL, p < .001). The incidence of postoperative complication was higher in the open group (20.0% vs. 66.5%, p < .001), especially wound infection (0% vs. 26.3%, p = .002). Median hospital stays were 14 days and 24 days in the laparoscopic and open groups, respectively (p < .001). In the laparoscopic group, hospital mortality was 0%. CONCLUSIONS: The laparoscopic approach for small bowel and colorectal perforation in an emergency setting is a safe procedure in carefully selected patients and may contribute to decreased intraoperative blood loss, shortened hospital stay, and decreased incidence of postoperative complications, especially wound infection.
