The role of rectocele repair in targeted patients with obstructed defaecation

Introduction  Obstructed defaecation is a complex disorder that poses serious management challenges. The purpose of this study is to review the functional results of surgery in women undergoing rectocele repair for obstructed defaecation, and in a targeted subgroup in which the rectocele was the only identifiable cause of their symptoms. Methods  All case notes were reviewed. Demographic details, preoperative symptoms, details of previous pelvic surgery, radiological and anorectal physiology results, operative procedure, post operative symptoms, length of follow-up and details of further pelvic reconstructive surgery were recorded. To enter the targeted group, patients (i) had not undergone previous pelvic surgery, (ii) had presented with obstructive defaecation, (iii) had a proctogram that demonstrated a rectocele with no or partial intrarectal intussusception and (iv) had no other functional abnormality in colonic transit studies, endoanal ultrasound or anorectal physiology. Results  Eighty-two case notes were reviewed. All experienced obstructed defaecation. Forty-two women underwent a per-anal plication of the rectocele, 33 had a transperineal plication and levatorplasty and seven a mesh repair. A total of 63 (77%) women were pleased with the result, though symptoms later returned in 17 (27%) of them. 26 (31%) had further surgery in an attempt to improve their defaecatory difficulties. Sixteen women were eligible for the targeted group. All had a good early result though symptoms returned in three women. Two (12%) had further surgery. Conclusion  Careful preoperative patient selection is vital to improve outcomes. Preoperative counselling of all patients undergoing rectocele repair is of extreme importance, in particular explaining the evolving nature of pelvic floor dysfunction and the possible need for further reconstructive surgery.
