BACKGROUND AND STUDY AIM: The aim of this study was to analyze objectively the role of the muscular graft in the continence using manometric study in the patients who underwent pseudocontinent perineal colostomy after abdominoperineal resection for rectal adenocarcinoma.
PATIENTS AND METHODS: This was a retrospective study including all the patients from January 2002 to December 2009 who underwent an abdominoperineal resection followed by perineal pseudocontinent colostomy for ultra-low rectal adenocarcinoma and agreed to perform the manometric evaluation of the muscular graft.
RESULTS: Fifteen patients were included, six males and nine females, with a mean age of 50 years. According to Kirwan’s classification, 2 (13.3%) patients had normal continence (Stage A) had 10 (66.6%) no soiling (stage B) and 3 (20%) patients had minimal soiling (Stage C). The manometric evaluation was performed after a median period of 12 months post-surgery. The mean maximal resting and squeeze pressures were respectively 41 cmH2O and 59 cmH2O and the mean colonic sensory volume was 12 ml.
CONCLUSION: This study showed that the musculae graft of Pseudocontinent Perineal colostomy acted as a hypotonic sphincter that pressure can increase during the voluntary squeeze. These data may help to clarify the functional outcomes of this technique after APR for ultra-low rectal adenocarcinoma.
