Emergent Laparoscopic Colectomy Is an Effective Alternative to Open Resection for Benign and Malignant Diseases: a...

The aim of this study is to compare the perioperative outcomes between laparoscopic and open resections performed for colonic emergencies. A systematic search of the literature identified previously published comparative studies regarding emergent laparoscopic colectomy (ELC) and emergent open colectomy (EOC). Meta-analysis was performed utilizing a pooled odds ratio (OR) for dichotomous variables and a weighted mean difference (WMD) for continuous variables with 95 % confidence intervals (CIs). Eleven studies involving 752 patients were identified. Although operation time was noted to be significantly shorter for EOC, patients post-ELC had significantly lower overall morbidity (OR 0.44; 95 % CI 0.30, 0.66; P < 0.0001). Meanwhile, recovery time for post-ELC patients was significantly shorter, as was the length of hospital stay (WMD -2.78 days; 95 % CI -3.17, -2.38; P < 0.00001), the time to regular dietary habits (WMD -1.32 days; 95 % CI -2.51, -0.13; P = 0.03), and the time to recover bowel movement (WMD -0.55 days; 95 % CI -0.89, -0.22; P = 0.001). Reoperation rate and mortality were found to be comparable between ELC and EOC. The R0 resection rate and the number of lymph nodes harvested were also comparable between ELC and EOC for malignant diseases. Whether for benign or malignant disease, ELC is a safe and feasible procedure for colonic emergencies compared with EOC, despite being relatively time-consuming.
