Efficacy of two different surgical techniques combined in the treatment of rectocele

摘要

Rectocele is defined as the herniation of rectal wall due to a rectovaginal septum defect in direction of the vagina. In most of cases it is a result of vaginal delivery or repeated increases of intra-abdominal pressure due to chronic constipation. Some patients can develop rectocele as a consequence of congenital or inherited weakness of the pelvic support system. The rectopexy procedure by a single mechanical stapler allows to ablate the exceeding tissue. This surgery is performed through transanal access without laparotomy, by means of a circular stapler which simultaneously resects portion of the rectal wall and re-anastomizes it. Also the technique of sequential transfixed stitches (TSTS) represents a minimally invasive procedure for the rectocele treatment, allowing the performance of a complete plasty of rectal wall through transanal access. Hence, starting from a more effective stadiation of rectocele, the authors of this study will show the advantages of an endorectal approach for the treatment of the above-mentioned disease using both methods. A total of 25 female patients attending our colonproctology outpatient department, with an age ranging between 38 and 63 years, have been selected for our study; following a careful assessment of stadiation, they have undergone rectopexy with circular stapler first, thereafter fulfilling the surgery with TSTS. the mean duration of hospital stay was 2.5 days (range 2–3). Twelve patients out of 25 have shown early complications, and 11 patients late ones. Among the early complications, 3 patients reported pain (12 %), 3 patients urinary retention (12 %), and 2 patients bleeding (8 %). Among late complications, 5 cases of urgency defecation disorders (>4 months) (20 %), 1 intestinal flatus incontinence (4 %), 1 stenosis (4 %), 2 prolonged pain and 2 cases of persistent obstructive defecation syndrome were reported. No cases of life-threatening local or pelvic sepsis as well as of rectovaginal fistulae were reported. At the 6 months post-surgery evaluation, neither rectocele recurrence nor prolapse was observed. The association of circular stapler and TSTS in the rectopexy treatment of rectocele showed its short-term efficacy, producing an improvement of patient’s clinical conditions, without inducing further alterations of pelvic statics, of the sphincteric tone as well as of rectum emptiness deficit.
