Overview

Retrospective analysis uncovers risks of anastomotic stricture and obstructive symptoms in 77 patients, suggesting interventions may improve quality of life.

Key Points

  • This research investigates the risk factors for anastomotic stricture and obstructive symptoms after double-flap reconstruction following proximal gastrectomy.
  • Retrospective analysis of 77 patients undergoing double-flap technique from 2014 to 2022.
  • Evaluation of technical factors such as suturing methods and mucosal detachment.
  • Intraluminal pressure analysis with ex vivo pig stomach models to assess obstruction sites.
  • Anastomotic stricture requiring balloon dilatation occurred in 10 patients (13%).
  • Mucosal detachment identified as an independent risk factor (OR: 48, p = 0.001).
  • Moderate or severe obstructive symptoms were reported by 59% of patients after surgery.
