Benefits of laparoscopic-assisted colectomy for colon polyps: a case-matched series

To clarify the true benefits of laparoscopic-assisted colectomy by comparing clinical outcomes from a series of laparoscopic right colectomies with matched open colectomies, all performed for the singular indication of polyp not amenable to colonoscopic removal.

A retrospective case-matched study was performed of consecutive patients undergoing laparoscopic-assisted right hemicolectomy for polyps between January 1992 and July 1997. Each case was matched to a control undergoing the equivalent open procedure for the same indication during the same time period.

Thirty-eight patients undergoing laparoscopic-assisted right hemicolectomy for polyps were identified, and matches were found. The conversion rate was 18.4% (7/38), 21.4% early in the series and 10% in later experience. Operative times were longer for laparoscopic-associated colectomy (median, 208 minutes vs 150 minutes, P < .001). Laparoscopic-assisted colectomy resulted in shorter postoperative ileus (time to flatus, 3.0 vs 4.0 days, P < .001; time to bowel movement, 3.5 vs 5.0 days, P < .001) and in earlier tolerance of regular diet (3.5 vs 6.0 days, P < .001). Fewer days of narcotic administration were required by the laparoscopic group (3.0 vs 4.5 days, P < .001). This resulted in a significantly shorter length of hospital stay (4.0 vs 7.0 days, P < .001). There was no significant difference in the incidence of postoperative complications.

Laparoscopic right hemicolectomy has significant patient benefits. These benefits are apparent when procedures of equal complexity and equivalent indications are compared. Laparoscopic-assisted resection has become our preferred approach for polyps not amenable to colonoscopic polypectomy.
