Objective: To compare the operative outcomes, postoperative pain, and subsequent convalescence after laparoendoscopic single-site surgery (LESS) or conventional laparoscopic surgery for adnexal preservation.
Study design: From December 2009 to September 2010, 63 patients underwent LESS (n = 33) or a conventional laparoscopic surgery (n = 30) for cyst enucleation. The overall operative outcomes including postoperative pain measurement using the visual analog scale (VAS) were evaluated (time points 6, 24, and 24 hours). The convalescence data included data obtained from questionnaires on the need for analgesics and on patient-reported time to recovery end points.
Results: The preoperative characteristics did not significantly differ between the two groups. The postoperative hemoglobin drop was higher in the LESS group than in the conventional laparoscopic surgery group (P = 0.048). Postoperative pain at each VAS time point, oral analgesic requirement, intramuscular analgesic requirement, and the number of days until return to work were similar in both groups.
Conclusion: In adnexa-preserving surgery performed in reproductive-age women, the operative outcomes, including satisfaction of the patients and convalescence after surgery, are comparable for LESS and conventional laparoscopy. LESS may be a feasible and a promising alternative method for scarless abdominal surgery in the treatment of young women with adnexal cysts
