Article Abstract
Background: Technique and functional outcomes of anorectal reconstruction using an antropyloric graft have been reported previously. This technique had reasonable initial outcomes but lacked voluntary function.
Objective: We hereby report the initial results of patients who underwent gracilis muscle wrapping around the perineally transposed antropyloric valve in an attempt to improve voluntary fecal control.
Setting: This study was conducted at a single tertiary care institution.
Patients: Eight adult patients (7 men and 1 woman) with a median age of 38 years (range, 19-51 years) underwent this procedure. Seven patients already had anorectal reconstruction with a transposed antropyloric valve, and 1 patient with severely damaged anal sphincter complex underwent single-stage composite antropylorus transposition with a gracilis muscle wrap.
Main Outcome Measures: The primary outcome measures were anatomical integrity and functional status of the composite graft in the perineum.
Results: No operative mortality or serious procedure-related morbidity occurred in any patient. The median postoperative resting pressure was 29 mmHg (range, 22-38 mmHg) and squeeze pressure was 72.5 mmHg (range, 45-267 mmHg). There was a significant improvement in the squeeze pressure following surgery (p = 0.039). Also, the St. Mark's incontinence scores significantly improved in all patients and varied between 7 and 9 (p = 0.003). The ability to defer defecation and the reduced frequency of leakage accidents were the prime reasons for improved postgraciloplasty outcomes in these patients. On personal interviews, all patients who underwent this procedure were satisfied with the results of their surgery.
Limitations: A longer follow-up with a larger sample size is required. Quality-of-life data have not been evaluated in this study.
Conclusions: Gracilis muscle wrapping around a perineally transposed antropyloric valve is possible and improves the voluntary control and overall functional outcomes in a select group of patients with end-stage fecal incontinence requiring anal replacement (Supplemental Digital Content 1, http://links.lww.com/DCR/A173).

Despite significant advancements in the field of medicine, management of complex obstetric perineal injuries remains a challenge. Although several surgical techniques have been described, no techniques have provided satisfactory long-term results. Recently, a perineal transposed antropyloric valve has been used for anorectal reconstruction in patients with damaged or excised anal sphincters.

Background: Severe fecal incontinence has a significant negative impact on patient well-being. Current surgical methods of total anorectal reconstruction to substitute a colostomy have suboptimal results. A composite graft using antropyloric valve transposition and gracilis wrap has been described with good outcomes.

Background: Surgical removal of the anal canal and sphincter for carcinoma results in end-stage fecal incontinence (ESFI) and requires a permanent colostomy resulting in significant impact on quality of life. Presently, there are limited options for EFSI. The successful use of pedicled antropyloric valve (APV) based on left gastroepiploic artery as an alternative to permanent colostomy has previously been described.

Background: Technical feasibility of inferior rectal nerve anastomosis to the anterior vagus branch of the perineally transposed antropyloric valve for total anorectal reconstruction has been previously demonstrated in cadavers. To the best of our knowledge, the present study is the first report of using this procedure in humans.
Methods: Eight patients [mean age 35.
