Abstract:

Rectocele is essentially a posterior vaginal wall hernia caused by a weak rectovaginal septum, The prevalence rate of women over 50 years old is 30% ～ 50%. Its outstanding clinical manifestations are difficulty in defecation, a sense of incomplete defecation, and often accompanied by distension and discomfort in the perineal area, some patients often help defecate by hand. Enduring the torment of these syndromes for a long time causes great burden to patients psychologically and physically. The conservative treatment of moderate and severe rectocele is not effective, and the patients finally choose surgical treatment to strengthen the weak and defective rectovaginal septum and eliminate the abnormal protrusion structure. At present, clinical studies have reported that combined with internal sphincteral lysis is effective in the treatment of rectocele, but the indication of this operation is not clear. This article mainly reviews the progress of the application of internal sphincteral lysis in the surgical

treatment of rectocele, to further clarify the indications of this operation, and to provide a reference for operators to choose the best operation for patients with rectocele.

Key words: Rectocele, Lysis of internal sphincter, Clinical progress
