Background: Antimesenteric cutback end-to-end isoperistaltic anastomosis (Sasaki-Watanabe anastomosis; Sasaki-W anastomosis), which was developed in our department, is a novel hand-sewn anastomotic technique for Crohn's disease intended to prevent anastomotic stenosis and preserve the peripheral circulation. Aim: The aim of the present study is to present the surgical technique of Sasaki-W anastomosis and to assess the safety and the early results of the surgical anastomotic recurrence of Sasaki-W anastomosis. Patients and Methods: The present study was a single-center retrospective cohort study. As an early-period group, 13 patients with Crohn's disease, who were mainly selected from cases considered to be at high risk of recurrence, underwent 15 Sasaki-W anastomoses from August 2009 to January 2012. As a late-period group, 36 patients with Crohn's disease, who were selected regardless of risk factors, underwent 37 Sasaki-W anastomoses from September 2016 to March 2020. The medical data including patient characteristics, surgical records, postoperative details, and surgical recurrences were assessed. Results: There were no intraoperative complications. With a median follow-up of 107 mo, surgical recurrence occurred in one patient at 106 mo after surgery in the early-period group. The cumulative surgical recurrence-free rate in the early-period group was 100% at 5 y and 86% at 10 y after surgery. No patients required reoperation in the late-period group. Conclusion: Sasaki-W anastomosis is safe and feasible. Although long-term study is needed, this anastomotic technique can be a reasonable operative option for Crohn's disease.
