ARTICLE HIGHLIGHTS
Research background

The use of intra-operative colonic lavage (IOCL) with primary anastomosis remains controversial in the emergency left-sided large bowel pathologies. There is little literature present that concludes the effectiveness of IOCL over its alternatives, including Hartmann’s procedure, manual decompression and subtotal colectomy.

Research motivation

To establish safety and effectiveness of IOCL, compared to Hartmann’s procedure, manual decompression and subtotal colectomy

Research objectives

To review the perioperative outcomes of IOCL compared to other modalities of bowel preparation for left-sided colorectal surgery.

Research methods

Electronic databases were searched for articles employing IOCL. Studies meeting inclusion criteria were reviewed and information regarding variables of interest were extracted. Odds ratio and weighted mean differences were estimated for dichotomous and continuous outcomes respectively. Single-arm meta-analysis was conducted using DerSimonian and Laird random effects.

Research results

Of 28 studies were included in this meta-analysis. 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 (weighted mean differences = -7.750; 95%CI: -13.504 to -1.996; P = 0.008) compared to manual decompression and an increased operating time. Overall mortality rates with IOCL were 4% (95%CI: 0.03-0.05). Rates of anastomotic leak and wound infection were 3% (95%CI: 0.02-0.04) and 12% (95%CI: 0.09-0.16) respectively.

Research conclusions

IOCL leads to similar rates of post-operative complications compared to other procedures.

Research perspectives

More extensive studies are needed to assess the outcomes of IOCL for emergency left-sided colonic surgeries.
