Background: Stapled anastomotic techniques in colorectal surgery are varied. Data comparing the short-term efficacy of end-to-side (ETS) versus end-to-end (ETE) colorectal anastomosis are limited. This single centre cohort study aimed to compare outcomes between ETS and ETE techniques in patients undergoing colorectal anastomosis. The primary endpoint was anastomotic leak.

Methods: A retrospective, cohort study of patients undergoing elective left-sided colorectal surgery was performed in University Hospital Limerick. Consecutive cases using ETS and ETE anastomotic techniques were retrospectively assessed in chronological order. Data were extracted from chart reviews, NIMIS and theatre logbooks.

Results: Seventy-five consecutive cases from each cohort were analysed retrospectively. Comparing ETS with ETE, there were no differences in age (mean 64.8 vs. 63.3 years, P=0.506), sex (male: 41% vs. 55%, P=0.102) and surgical approach (minimally invasive 70.6% vs. 93.3%, P=0.071) between the patient groups. More radiologically-proven anastomotic leaks were encountered in the ETE group (0% vs. 6.7%, P=0.022).

Conclusions: Anastomotic leak rates were significantly higher using an ETE technique after left-sided colorectal surgery. Adequately powered, prospective is required to validate these findings.
