Anastomotic leaks: technique and timing of detection

Despite the proven benefits of laparoscopic colorectal surgery, the rate of anastomotic leaks has not changed. This study looks at the time of presentation of anastomotic leaks between laparoscopic and open colectomies.

Retrospective chart review was performed between July 2008 and 2012. Two groups were created, laparoscopic and open. The time of presentation of significant leaks requiring reoperation were compared between the groups by index colectomies. Statistical analysis is presented as paired t test and chi-square test (P < .05).

From 1,424 segmental colectomies, the anastomotic leak rate between the two groups was not statically significant (P = .69). No difference in the time of leak detection was evident (P = .67). Mortality rate was equal between the groups. The overall complication rate of the entire cohort was statically significant (P ≤ .001).

The timing of anastomotic leak detection does not differ between laparoscopy and open colorectal resections.
