However, anastomotic stricture remains a major concern, leading to obstructive symptoms and impaired postoperative quality of life (QOL). This study aimed to identify risk factors for anastomotic stricture and obstructive symptoms after PG with DFT reconstruction.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This single\u2010center, retrospective study analyzed 77 patients who underwent DFT reconstruction between 2014 and 2022. The impact of technical factors, including suturing methods and mucosal detachment, was evaluated. In addition, intraluminal pressure analysis was performed using ex\u00a0vivo pig stomach models to assess sites contributing to obstructive symptoms.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Anastomotic stricture requiring balloon dilatation occurred in 10 patients (13%), with mucosal detachment of the esophagus identified as an independent risk factor (odds ratio [OR]: 48, 95% confidence interval [CI]: 4.47\u2013515,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.001).

Moderate or severe obstructive symptoms 1\u2009month after surgery were reported by 59% of patients, with continuous suturing for esophago\u2010stomach fixation (E\u2010S fixation) increasing the risk (OR: 4.50, 95% CI: 0.98\u201320.7,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.054).
