title: Timing for a Laparoscopic Myomectomy During the Menstrual Cycle.
abstract: OBJECTIVE
  To determine whether the different phases (follicular phase, luteal phase, or menstruation) of the menstrual cycle could affect the operative blood loss during a laparoscopic myomectomy.
  
  
  METHODS
  Retrospective comparative study.
  
  
  METHODS
  University hospital.
  
  
  METHODS
  A total of 220 patients who underwent a laparoscopic myomectomy were classified into the follicular phase (n = 90), luteal phase (n = 93), and menstruation group (n = 37) on the basis of the adjusted day of the menstrual cycle.
  
  
  METHODS
  Laparoscopic myomectomy.
  
  
  RESULTS
  The operative blood loss during the laparoscopic myomectomy was measured. The baseline demographics (age, body mass index, and myoma characteristics) were similar among the 3 groups. No significant differences were observed in the operative blood loss (p = .231) and in the hemoglobin change (p = .526) among the 3 groups. In addition, no other statistical differences were found in terms of the other operative results, including the operative time, the length of hospital stay, and operative complications.
  
  
  CONCLUSIONS
  The different phase of the menstrual cycle had no effect in the operative blood loss during laparoscopic myomectomy. Therefore, the menstrual cycle is not an important factor to determine the optimal timing of a laparoscopic myomectomy.
