Transrectal Evaluation After Discoid Resection for Endometriosis Intestinal

Endometriosis is an inflammatory, benign, oestrogen-dependent condition that affects 10-15% of women of reproductive age. It is characterised by the presence of endometrial tissue, glands and stroma, outside the uterine cavity. Endometriosis may present in the pelvis as superficial peritoneal, ovarian or deep infiltrating. The reported prevalence of bowel or recto-vaginal space involvement among women with endometriosis ranges from 5% to 25% (2). Surgery is the treatment of choice for deep endometriosis with bowel involvement when drug therapy alone is ineffective in treating symptoms. Surgical techniques for intestinal endometriosis can be divided into full-thickness techniques (discoid or segmental resection) and non-full-thickness techniques (shaving).

Focusing on women who underwent a discoid resection, 3.7% of 80 reported a recto-vaginal fistula and the same percentage showed early rectorrhagia requiring endoscopic treatment after surgery. In general surgery rectosigmoidoscopy has shown encouraging results as a feasible, safe and effective technique in reducing the risk of complications related to intestinal anastomosis. There are no studies in the literature evaluating the role of rectosigmoidoscopy as a routine practice in gynaecological surgery for endometriosis, so we rely on the experience of general surgeons. In particular, the lack of data does not allow us to evaluate the feasibility of rectosigmoidoscopy during deep endometriosis surgery in terms of the success of the procedure itself and the additional operative time taken. The latter aspect is also important from the point of view of health policy due to the increased cost of the operating theatre directly related to the time taken for the procedure.
