Background
Anastomotic leakage is the most serious surgical complication following colorectal resection, and surgical intervention is often required. The purpose of the study was to investigate short- and long-term outcomes after reoperation for anastomotic leakage.
Method
Patients with a symptomatic anastomotic leakage following a laparoscopic colorectal cancer resection from January 2009 to December 2014 were identified from our local prospective database. Patients were grouped according to the management of anastomotic leaks: local, lap, or open approach. Primary outcomes were length of stay, chance of bowel continuity, and overall mortality.
Results
A total of 113 patients were included. The median follow-up time was 40 months (0–82 months). Overall mortality was significantly associated with UICC stage III–VI disease (vs. UICC stage I–II disease) [adj. HR 5.35 (CI 2.32–12.4), p = 0.0001] and minimal invasive reoperation compared with open approach [local: adj. HR 0.12 (CI 0.03–0.52), p = 0.004; lap: adj. HR 0.32 (CI 0.12–0.86), p = 0.024]. Chance of bowel continuity was significantly increased in younger patients below 67 years [adj. OR 6.15 (1.76–21.5), p = 0.004] and following a local procedure [adj. OR 7.45 (1.07–51.8), p = 0.043]. Patients in the open group had significantly longer length of stay and time to initiation of adjuvant chemotherapy compared with those in the lap group.
Conclusion
Our data confirms that minimal invasive reoperation for anastomotic leakage is a safe and feasible approach associated with short- and long-term advantages and can be chosen in selected cases.
