- Treatment of rectal prolapse(2016) MURAD-REGADAS, Sthela M.; PINTO, Rodrigo A.Numerous approaches have been described for the treatment of rectal prolapse. The two basic categories of operation are transabdominal and perineal. The former type tend to be more durable with lower recurrence rates but at the expense of higher morbidity. The latter group tends to be safer but associated with higher recurrence rates and less functional recovery. More recently, the abdominal approaches have been modified to be laparoscopically accomplished in most cases. Different methods and indications for rectal prolapse management will be described and discussed based in literature evidences.

We aimed to evaluate the risk factors related to the incidence, severity, and time course of postoperative complications of TEM. This is a prospective study of postoperative complications in 53 patients (> 18 years old) with benign or early rectal neoplasia who underwent TEM with curative intention or, for higher stages, palliation. Outcome measures included age, sex, American Society of Anesthesiologists score, neoadjuvant chemoradiotherapy, lesion height and size, pathologic margins, tumor histology, and suture type. Overall morbidity was 50 %. Temporary fecal incontinence was the most frequent complication (17.3 %). Complication rates of Clavien-Dindo grades I and II were 21.1 % and those of grades III and IV 3.8 %. Of patients with complications, more had lesions under the first rectal valve than over the first valve (61.54 % vs 38.46 %, p = 0.04). Patients submitted to chemoradiotherapy had a 24-fold greater chance of presenting grade II complications (p = 0.002). When the surgical defect was treated using the TEM device to perform the suture, the chance of having grade III complications was reduced 16-fold (p = 0.04). Fifty-three percent of complications occurred in the first 10 days and 95 % within 20 days. Postoperative complications after transanal endoscopic microsurgery for the treatment of rectal neoplasia are frequent, acceptable, and usually controllable with pharmacologic treatment. Over time the nature of complications is continuous, centered on the first 20 days after surgery.
