Multicenter controlled trials are needed for stronger evidence to change practice.īoccola MA, Buettner PG, Rozen WM et al (2011) Risk factors and outcomes for anastomotic leakage in colorectal surgery: a single-institution analysis of 1576 patients. The ECPS device could have a positive impact by reducing AL rates in left-sided colorectal anastomosis. The patient in the ECSP group required an urgent Hartmann’s procedure Conclusions AL in the MCS group required reoperation in seven cases (5.8%), the remaining seven patients were treated conservatively. After adjusting the cases with propensity score matching (119 cases MCS versus 60 ECPS), AL was observed in 14 (11.8%) patients in MCS group and in 1 (1.7%) patient in the ECPS group ( p = 0.022). Factors significantly associated with AL were American Society of Anesthesiologists score ( p = 0.025) and type of circular stapler used ( p = 0.021). Overall, AL was observed in 25 (9%) cases. A MCS anastomosis was performed in 218 patients and ECPS anastomosis in 61 (21.9%). Two hundred seventy-nine patients met the inclusion criteria. The ECPS cases were matched to MCS cases by propensity score matching to obtain comparable groups of patients.
The primary end point was the risk of AL depending on the type of circular stapler used. MethodsĪ cohort study was carried out on consecutive patients between January 2017 and February 2020 in whom left-sided stapled colorectal anastomosis above 5 cm from anal verge was performed.

The aim of this study was to assess the impact of technical improvements in the Echelon Circular™ powered stapler (ECPS) on the left-sided colorectal AL rate compared to current manual circular staplers (MCS). Improvement in devices for performing anastomosis is a modifiable factor that could reduce AL rates. Several risk factors for anastomotic leakage (AL) following colorectal surgery have been described.
