Complex Obstetric Perineal Injury Reconstruction Using Antropyloric Valve Transposition
Saket Kumar,Noushif Medappil,Sunil Kumar Singh,Abhijit Chandra 대한대장항문학회 2020 Annals of Coloproctolgy Vol.36 No.1
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. We describe this technique in the case of complex obstetric perineal trauma with extensive tissue loss, presenting with end stage fecal incontinence. The functional outcome after this procedure was evaluated. The patient tolerated the surgery well, and there were no procedure-related upper gastrointestinal disturbances. Short-term functional outcomes were encouraging. At the 36-month follow-up, the patient’s neoanal resting and squeeze pressures were 50 and 70 mmHg, respectively. The postoperative St. Mark’s incontinence score was 7. Perineal antropyloric valve transposition is feasible and can be successfully applied in the management of end-stage fecal incontinence associated with complex obstetric perineal injury.

Purpose: Perineal transposition of the antropyloric valve following an anorectal excision as a substitute for a permanent colostomy has recently been reported in humans. However, the problem of neural control still remains in these patients. Our aim herein was to study the anatomical feasibility of an anastomosis between the pudendal nerve branches (inferior rectal nerve) innervating the external anal sphincter and the anterior vagal branches of the perineally-transposed antropyloric segment in cadavers. Methods: The antropyloric segment, along with its carefully dissected branch of the anterior vagus, was mobilized based on the left gastroepiploic pedicle in six fresh human cadavers. The antropyloric valve was then transposed in the perineum after the pudendal nerve branches had been dissected out, and an approximation of these two nerves was performed to ascertain the technical feasibility of their neural anastomosis. Results: The anterior vagus innervating the antropylorus could be harvested in all cadavers below the hepatic division of the main vagus trunk. The inferior rectal nerve or its branches were found consistently around the 3 or the 9 o’clock position in the ischioanal fossa. An anatomical tension-free approximation of the anterior vagus branch (of the transposed antropyloric segment) to the inferior rectal nerve in the perineum was feasible in all the cadavers studied. Conclusion: An inferior rectal nerve anastomosis with the anterior vagal branch of the perineally-transposed antropyloric segment can be achieved anatomically. This preliminary step can be the basis for future animal studies and subsequent clinical application of the procedure for possible neural control of the transposed antropyloric segment in the perineum.
