BACKGROUND: Anastomotic leakage is still a feared complication after left-sided colonic resections. Various types of “anastomotic leak testing methods” are described in current literature. In this study we evaluated the use of intraoperative flexible endoscopy in comparison to conventional air leak testing after performing a circular stapled anastomosis in left-sided laparoscopic colon surgery.
METHODS: A retrospective database consisting of 130 patients with left sided colonic resections between 01/2015 and 12/2019 at our hospital was evaluated. After performing a circular stapled anastomosis flexible endoscopy was done in 69 cases, 61 patients were controlled with a conventional air leak test. Intraoperative and postoperative complications were recorded and retrospectively evaluated.
RESULTS: In the flexible endoscopy group, we observed complications in 13,04%, in the conventional air leak testing group in 9,83%. Postoperative anastomotic leakage was observed in 10,14% in the flexible endoscopy group and 4,91% in the conventional air leak test group. In 10,14% a positive air leak test was seen in the flexible endoscopy group and 11,47% in the conventional air leak testing group. In those cases, we observed no postoperative complications in the first group, in the conventional group we had two anastomotic leakages and one infected haematoma.
CONCLUSIONS: In the case of a positive air leak, flexible endoscopy offered a more exact detection of the leak. In those cases, no anastomotic leakage was observed postoperatively. In our opinion, flexible endoscopy should be recommended for testing the anastomosis intraoperatively in every left-sided colon surgery.
