Background: Anastomotic recurrence after bowel resection is problematic in patients with Crohn's disease. Antimesenteric functional end-to-end handsewn (Kono-S) anastomosis is associated with a low risk of anastomotic recurrence in patients with Crohn's disease.
Impact of innovation: Kono-S anastomosis is effective but may be time-consuming. This study aimed to describe stapled antimesenteric functional end-to-end anastomosis for patients with Crohn's disease.
Technology materials and methods: The mesentery of the affected bowel segment was divided. A 5-cm-wide stapled functional end-to-end anastomosis was performed approximately 6 cm from the affected segment. The bowel was divided transversely exactly 90° to the intestinal lumen and the mesentery, and a supporting column was then constructed.
Preliminary results: From January 2018 to June 2021, 17 stapled antimesenteric functional end-to-end anastomoses were performed. The mean operative time was 106 (range, 80-135) minutes, and the time to construct the stapled antimesenteric functional end-to-end anastomosis was 21 (range, 18-28) minutes. The mean follow-up time was 8.9 (range, 1-15) months. In total, 10 patients underwent surveillance endoscopy. The average Rutgeerts score was 0.8 (range, 0-4), and the incidence of endoscopic recurrence was 11.8%. No postoperative mortality or anastomotic leakage was observed.
Conclusion: Stapled antimesenteric functional end-to-end anastomosis may be a safe and time-saving procedure for patients with Crohn's disease.
Future directions: Further prospective studies with a large sample size are warranted.
