Retrospective Study of Collection Methods in Laparoscopic Myomectomy

After a FDA recommendation in April 2014, power morcellation (PM) in laparoscopic myomectomy (LM) has become less common. We now collect a myoma using manual morcellation (MM) from a wound in the umbilical region. In this study, we compared the PM and MM methods.

The subjects were 69 patients who underwent LM from April 2013 to March 2016 using PM (n = 37) or MM (n = 32). With PM, the myoma was collected using a 4-hole 12-mm parallel trocar in the left lower abdomen. Using MM, an EZ ACCESS^TM (2-cm skin incision) was placed on the umbilical region, and the myoma was put in a collection purse and guided into the access hole for MM using scissors under direct vision.

None required allogeneic transfusion or a transition to open surgery, and had surgical or post surgical complications. At multiple linear regression analysis, which was adjusted by age, body mass index, and intraoperative blood loss, significant difference was not observed in operation time between the PM and MM groups.

Manual morcellation was found to be a safe method for collection of myoma that prevents scattering of tissues and does not prolong the operation time.
