Functional Outcome of Sphincter Saving Procedure

Abstract

Introduction: Intersphincteric resection of low rectal tumors.is a surgical technique extending rectal resection into the intersphincteric space. This procedure is performed by a synchronous abdominoperineal approach with mesorectal. Excision and excision of the entire or part of the internal sphincter. Aim of the Work: Is to evaluate the functional outcome of sphincter sparing. Patients: 10 patients who meet the criteria of ISR possibility and candidates for sphincter saving procedures this study was conducted at Beni Suef university hospitals between January 2019 and March 2020. Methods: Total ISR involves complete excision of the internal sphincter. The cut line is at the intersphincteric groove. B. Subtotal ISR involves partial excision of the internal sphincter. The cut line is between the dentate line and the intersphincteric groove. C. Modified partial ISR the cut line is below the dentate line on one side of the tumor. On the opposite side of the tumor, the cut line is above the dentate line. D Partial ISR the cut line is at or above the level of the dentate line. Results: Showed that out of 10 patients underwent ISR, 6 patients were highly satisfied with Grade I continence according to Kirwan’s grade. While 4 patients were Grade II, i.e.: Incontinent to flatus. Conclusion: In low rectal cancer, the sphincter saving have certainly demonstrated an indisputable good functional outcome, in terms of stoma avoidance and adequate continence.
