Abstract:
Objective:To investigate the clinical efficacy of laparoscopic resection of retrorectal cystic lesions.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 58 patients undergoing laparoscopic resection of retrorectal cystic lesions in the Peking Union Medical College Hospital, Chinese Academy of Medical Sciences from August 2012 to August 2019 were collected. There were 5 males and 53 females, aged from 15 to 70 years, with a median age of 38 years. All the 58 patients underwent laparoscopic resection of retrorectal cystic lesions and the combined operation through the transsacral approach was chosen according to the patient condition. Observation indicators: (1) surgical situations; (2) postoperative situations; (3) postoperative histopathological examination; (4) follow-up. Patients were followed up regularly using outpatient examination once every 6 months during the first postoperative year and once every 12 months after the first postoperative year. The recurrence of cysts was evaluated by computed tomography or magnetic resonance imaging examinations during the follow-up up to August 2020. Measurement data with normal distribution were represented as Mean± SD and measurement data with skewed distribution were described as M(range). Count data were described as absolute numbers. Results:(1) Surgical situations: of the 58 patients, 54 cases underwent laparoscopic resection of retrorectal cystic lesions and 4 cases underwent laparoscopic resection of retrorectal cystic lesions combined with the transsacral approach operation. One of the 58 patients who had a huge cyst surrounding the rectum underwent transverse colostomy after repairing the damage of separated posterior wall of rectum. Two cases underwent preventive transverse colostomy because the external rectal wall heat injury could not be excluded after separation of the tight adhesion between cyst and rectum. The operation time and volume of intraoperative blood loss were (123±56)minutes, 20 mL(range, 5?500 mL) of 54 cases who underwent laparoscopic resection of retrorectal cystic lesions and (232±38)minutes, 90 mL(range, 30?800 mL) of 4 cases who underwent laparoscopic resection of retrorectal cystic lesions combined with the transsacral approach operation, respectively. (2) Postoperative situations: 7 of the 58 patients had complica-tions. Of the 7 patients, 2 cases had postoperative rectal fistula and were cured after the treatment of transverse colostomy combined with pelvic drainage, 2 cases had postoperative urinary tract infection and were relieved after anti-infection treatment, 2 cases had urinary retention after removal of catheter and were recovered after 3 weeks of re-indwelling catheter, and 1 case had poor incision healing of transsacral and was healed after wound dressing change. The duration of postoperative hospital stay of the 58 patients was (7±4)days. (3) Postoperative histopathological examination: results of the postoperative histopathological examination showed that there were 26 of 58 patients with epidermoid cyst, 20 patients with teratoma (2 cases with mature teratoma accompanied by mucinous adenocarcinoma and 1 case with mature teratoma accompanied by neuroendocrine carcinoma), 10 patients with dermoid cyst, and 2 patients with tailgut cyst. (4) Follow-up: 57 of the 58 patients were followed up for 2-85 months, with a median follow-up time of 51 months. Of the 57 patients who were followed up, 1 patient was diagnosed with buttock subcutaneous cyst at postoperative 8 months and treated with local excision, 1 patient was diagnosed with a small presacral cyst recurrence by pelvic magnetic resonance imaging at postoperative 6 months and continued follow-up as the cyst without obvious enlargement, and the other 55 patients had no cyst recurrence.Conclusion:The laparoscopic resection of retrorectal cystic lesions is safe and feasible.
