Abstract

OBJECTIVE
To compare the intraoperative and postoperative outcomes of laparoendoscopic single-site surgery (LESS) versus conventional laparoscopic surgery in women with ovarian mature cystic teratoma.
METHODS
A retrospective review of 303 women who underwent LESS (n=139) or conventional laparoscopic surgery (n=164) due to ovarian mature cystic teratoma was performed. Intra- and postoperative outcomes were compared between the two groups.
RESULTS
There was no intergroup difference in age, body weight, height, body mass index, comorbidities, tumor size, bilaterality of tumor, or the type of surgery. However, more patients in the LESS group had a history of previous abdominal surgery (19.4% vs. 6.7%, P=0.001). Surgical outcomes including operating time (89 vs. 87.8 minutes, P=0.734), estimated blood loss (69.4 vs. 68.4 mL, P=0.842), transfusion requirement (2.2% vs. 0.6%, P=0.336), perioperative hemoglobin level change (1.3 vs. 1.2 g/dL, P=0.593), postoperative hospital stay (2.0 vs. 2.1 days, P=0.119), and complication rate (1.4% vs. 1.8%, P=0.999) did not differ between LESS and conventional groups. Postoperative pain scores measured using a visual analogue scale were significantly lower in the LESS group at 8 hours (P=0.021), 16 hours (P=0.034), and 32 hours (P=0.004) after surgery, and 32 of 139 patients (23%) in the LESS group and 78 of 164 patients (47.6%) in the conventional group required at least one additional analgesic (P<0.001).
CONCLUSION
LESS was feasible and showed comparable surgical outcomes with conventional laparoscopic surgery for women with ovarian mature cystic teratoma. LESS was associated with less postoperative pain and required less analgesia.
