Peri-operative outcomes of patients with stage IV endometriosis undergoing robotic-assisted laparoscopic surgery

摘要

We analyzed peri-operative outcomes of 80 patients who underwent robotic-assisted laparoscopic surgery and were diagnosed with stage IV endometriosis (revised American Society for Reproductive Medicine) between January 2007 and December 2010 at a tertiary gynecologic oncology referral center with a fellowship training program. Eligible women had a combination of one or more factors: pelvic mass, sub-acute or chronic pelvic pain, dysmenorrhea, dyspareunia, elevated serum CA-125, diagnosed with stage IV endometriosis at surgery with robotic-assisted gynecologic procedures using the da Vinci ? Surgical System. The mean age was 43. 7 ± 7. 0 years, body mass index 27. 5 ± 7. 4 kg/m 2, and 23 (28. 9%) patients had prior endometriosis surgery. Presenting symptoms included: chronic pelvic pain (48. 8%), dysmenorrhea (40. 3%), and dyspareunia (33. 8%). Sixty-nine (86%) patients had pelvic masses (43 unilateral and 26 bilateral). Thirty-seven (46. 3%) had elevated CA-125 levels (mean 97. 9 ± 71. 6 U/ml). Forty-eight (60%) underwent robotic-assisted laparoscopic hysterectomy (RALH)/bilateral salpingo-oophorectomy (BSO), 9 (11. 3%) RALH/unilateral salpingo-oophorectomy (USO), 5 (6. 3%) modified radical hysterectomy, and 10 (13%) USO or BSO only. Four (5%) had ovarian cystectomies with excision of endometriotic implants. Three (3. 8%) underwent appendectomy and no patient required bowel resection. Four (5%) patients required conversion to laparotomy during the first 15 cases of this series [dense adhesions (3) and ureteral injury (1)]. Mean operative time was 115 ± 46 min, blood loss 88 ± 67 ml, and length of stay 1. 0 ± 0. 4 days. There were four (5%) complications (ureteral injury, cuff abscess, cuff hematoma, re-admission for nausea and vomiting secondary to narcotics) and no transfusions. One (1. 3%) patient underwent a second surgery for pain (dyspareunia). Robotic-assisted surgery for stage IV endometriosis resulted in excellent pain relief, with few laparotomy conversions or complications during a robotic learning-curve experience.
