Surgical Outcomes of Sliding Skin Graft for Anastomotic Stricture After Intersphincteric Resection

We evaluated surgical outcomes of sliding skin graft (SSG) for anastomotic stricture that developed after intersphincteric resection (ISR) for 75 patients with rectal cancer. A total of 5 patients (4 men, one woman) who underwent SSG for anastmotic stricture were evaluated retrospectively. A median age was 63 (range, 58-７５) years. One patient was performed preoperative chemoradiation therapy (pre-CRT). Partial and subtotal ISR were performed in 4 and one patient, respectively. All patients were observed for a median of 1,034 days (range, 559-3,010 days). Anastomotic stricture developed in 5 of 75 patients (6.7%). A median of operative duration and bleeding volume were 79.5 (25-136) min-utes and 10 (0-143) ml, respectively. Although reoperation was needed in one patient with pre-CRT, stricture was improved in all patients. Regarding the continence function of 4 patients, Kirwan grading scale showed ≥ Grade 2 in all patients. A procedure, SSG for anastmotic stricture developed after ISR was safety and effective. However, anastomotic stricture impacted on anal function after ISR.
