Retrospective Study of Collection Methods in Laparoscopic Myomectomy at Matsumoto City Hospital

Abstract

Objective : In laparoscopic myomectomy (LM), it is essential to remove myoma tissue without dispersing it into the abdominal cavity, as scattered tissue may later be diagnosed as malignant or lead to the development of parasitic myomas. In our hospital, we use Molsafe TM and an electric morcellator to retrieve myoma tissues ; however, we experienced a case in which removal was difficult using this surgical procedure. Herein, we report a retrospective analysis of cases of LM at our hospital. Method : We retrospectively analyzed 25 cases of uterine myoma who underwent LM between 2018 and 2024 at our hospital. Results : The median operation time was 174 min (120-405 min), the median intraoperative blood loss was 100 g (5-800 g), the median long diameter of the largest uterine myoma on preoperative MRI was 5.4 cm (3-11 cm), and the median number of myoma removed was one (one-seven). Using Molsafe TM and an electric morcellator, successful tissue retrieval was achieved in 24 of 25 cases (96 ％). However, retrieval was challenging in one case involving a uterine myoma with a long diameter of 11 cm. Conclusion : When retrieving uterine myoma tissues using Molsafe TM and an electric morcellator, caution should be taken if the long diameter of the uterine myoma is large, as it may be difficult to secure surgical space and remove the myoma due to its hardness.journal articl
