Abstract
The aim of this study was to compare the spillage rate and surgical outcomes between the leak-proof technique and the conventional technique in laparoscopy for large ovarian cysts (more than 15 cm in diameter) presumed to be benign tumours and free from adhesion. Thirty-five consecutive patients who underwent laparoscopy with the leak-proof technique between 2017 and 2019 (the practice change cohort) were compared retrospectively with 35 case-matched consecutive patients who underwent the conventional purse-string method between 2014 and 2016 (the historical cohort). In the practice change cohort, through the wound retractor in the umbilicus, large ovarian cysts were first covered with a sterilised vinyl membrane applied with a skin adhesive, then punctured, and the contents directly aspirated. The primary outcome was tumour spillage. The two cohorts had similar baseline characteristics. The spillage rate in the practice change cohort was significantly lower than in the historical cohort (0% vs 28.6%; p = .001). Other surgical outcomes, including operative time, operative blood loss, hospital stay, and operative complications were similar between the cohorts. In conclusion, laparoscopy with the leak-proof technique is reliable, safe, and easily implemented in the management of selected patients with large ovarian tumours and low probability of malignancy.
What is already known on this subject: Large ovarian cysts preclude the laparoscopic surgery because the size of the cyst interferes with adequate visualisation of the pelvic anatomy and confines the mobilisation of laparoscopic devices.
What do the results of this study add: Laparoscopy with the leak-proof technique is reliable, safe, and easily implemented in the management of selected patients with large ovarian tumours and low probability of malignancy.
What are the implications of these findings for clinical practice and/or further research: This technique is easily implemented and useful for most gynaecologic surgeons in treating extremely large ovarian cysts.
