Sacro-rectopexy by a posterior intersphincteric approach with anteroposterior perineoplasty and mucosal resection. Therapeutic proposal in descending peritoneum syndrome. Apropos of 23 cases

We report the results of a procedure aimed at correcting the disorders of rectal and perineal tone responsible for the descending perineum syndrome (DPS). The procedure, carried out by the perineal approach, combines a posterior intersphincteric sacro-rectopexy, an anterior perineoplasty via a pre-anal levator myorraphie, a posterior perineoplasty using a post anal repair technique and a mucosal resection aimed at freeing the anal canal. 22 F and 1 M, mean age 68 years, with DPS were operated on. Digitised rectography demonstrated pathological perineal descent (greater than 3 cm) in all cases and posterior rectal angulation at rest of more than 25 degrees (normal less than 10 degrees) confirming an important deterioration in perineal tone. Results after a mean follow up of 12 months (6 to 30 months) were excellent, with objective improvement in rectal bleeding, pain, mucosal prolapse and anal incontinence. In spite of an almost constant return to normal in the number of stools and their facility of evacuation improvement in the dyschesic syndrome (78% of patients) was subjectively variable. Improvement was judged to be very good in 34%, good in 33%, fair in 11%. Healing of mucosal lesions: solitary ulcer (n = 2), rectal inflammation (n = 2), ulcerated mucosal prolapse (n = 3) occurred in all cases within 1 month. Post operative rectography demonstrated a significant decrease in posterior rectal angulation and ano-coccygeal distance confirming the efficacy of the anatomical correction. No serious complications, in particular, infections, were noted under appropriate prophylactic antibiotic cover (Piperacillin) continued up to D5.(ABSTRACT TRUNCATED AT 250 WORDS)
