The use of intra-operative colonic lavage (IOCL) with primary anastomosis remains controversial in the emergency left-sided large bowel pathologies, with alternatives including Hartmann’s procedure, manual decompression and subtotal colectomy.
To compare the peri-operative outcomes of IOCL to other procedures.
Electronic databases were searched for articles employing IOCL from inception till July 13, 2020. Odds ratio and weighted mean differences (WMD) were estimated for dichotomous and continuous outcomes respectively. Single-arm meta-analysis was conducted using DerSimonian and Laird random effects.
Of 28 studies were included in this meta-analysis, involving 1142 undergoing IOCL, and 634 other interventions. IOCL leads to comparable rates of wound infection when compared to Hartmann’s procedure, and anastomotic leak and wound infection when compared to manual decompression. There was a decreased length of hospital stay (WMD = -7.750; 95%CI: -13.504 to -1.996; P = 0.008) compared to manual decompression and an increased operating time. Single-arm meta-analysis found that overall mortality rates with IOCL was 4% (CI: 0.03-0.05). Rates of anastomotic leak and wound infection were 3% (CI: 0.02-0.04) and 12% (CI: 0.09-0.16) respectively.
IOCL leads to similar rates of post-operative complications compared to other procedures. More extensive studies are needed to assess the outcomes of IOCL for emergency left-sided colonic surgeries.
Core Tip: Comparing the intra and post-operative outcomes of primary resection and immediate reconstruction after either intra-operative colonic lavage (IOCL), manual decompression or without IOCL against Hartmann’s procedure and subtotal colectomy in the management of colorectal emergencies, intraoperative colonic lavage was found to have largely similar rates of post-operative complications compared to other procedures. The operative duration was observed to be statistically longer in IOCL than without IOCL. However, hospitalization stay was significantly shorter in duration in those with IOCL compared to Hartmann’s. Thus, there may be merits in choosing IOCL especially for patients who are hemodynamically stable.
