Antimesenteric cutback end-to-end isoperistaltic anastomosis (Sasaki-Watanabe anastomosis) for Crohn's disease: Novel surgical technique and early results of surgical anastomotic recurrence.

ABSTRACT:

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.

Project description:BackgroundRobotic mitral repair is generally performed with four intercostal trocars and a minithoracotomy. We describe our technique and results with a totally-thoracoscopic closed chest approach using a 12 mm valveless trocar as "working port", without a minithoracotomy. We compared our results with this technique with a control group of robotic mitral repairs performed earlier with a minithoracotomy.MethodsReview of all patients with degenerative mitral valve disease who underwent robotic mitral valve repair surgery since December 2019 (n = 110). Patients with concomitant procedures (n = 8) were excluded. The remaining 102 patients were divided in two groups, depending on the approach used, minithoracotomy (n = 63) and totally thoracoscopic (n = 39).ResultsThere were no significant differences between groups regarding preoperative characteristics. All procedures were completed robotically as planned, and repair rate was 100%. The minithoracotomy group showed a higher percentage of leaflet resections (17.9% vs. 38.7%; p = 0.03). All surgical times were significatively reduced in the totally thoracoscopic group: Cardiopulmonary bypass (97 vs. 115 min, p = 0.0008), ischemic time (67 vs. 80 min, p = 0.0013) and total surgical time (185 vs. 225 min; p < 0.00001). There were no differences in ICU length of stay (1 day, p = 0.07) but hospital length of stay was shorter in the totally thoracoscopic group (4 days; p = 0.0001). Postoperative complications were similar between groups. MR at discharge was mild or less in all cases.ConclusionsRobotic mitral repair for degenerative disease can be safely performed as a closed-chest procedure, using a 12 mm trocar as "working port" and avoiding the need for a minithoracotomy. This approach does not seem to negatively affect the quality of the procedure by any measure, providing similar excellent clinical outcomes and repair rate. All surgical times were shorter in the closed-chest group.
