The aim of this study was to assess the feasibility and efficacy of laparoscopic myomectomy (LM) for large myomas. A subpopulation of 51 patients with myomas 8 cm or larger in diameter was selected from 155 patients who underwent LM at Kangbuk Samsung Hospital from July 2003 to November 2006. The mean age of the patients was 34.9±5.6 yr, mean parity was 0.6±0.9, and 8 patients had a previous operative history. The most common operative indication was a palpable abdominal mass (24 patients, 47%). The mean operating time was 85.6±38.9 min, and the mean diameter of the largest myoma was 9.3±1.8 cm. The mean change in hemoglobin concentration was 2.1±1.2 g/dL. Histopathological diagnosis included 49 patients of leiomyoma (96.1%) and 2 patients of leiomyoma with adenomyosis (3.9%). Postoperatively, a transfusion was done in 7 patients, and a case of subcutaneous emphysema was noted. None of the operations was switched to laparotomy. With the newly-developed screw and the port placement system that was modified from the Choi's 4-trocar method to obtain better surgical vision, LM of large myomas proved to be one of the efficient and feasible methods.

The canal TOT procedure is feasible and effective for mitigating the complications of the original TOT procedure. This technique might be especially useful in patients with cystocele because of the paravaginal defect as well as in patients with obesity or prior vaginal surgery. However, a large-scale and long-term followup study is required to verify the effectiveness of this technique.
