title: Changes in myometrial thickness during hysteroscopic resection of deeply invasive submucous myomas.
abstract: OBJECTIVE
  To evaluate the efficacy of hysteroscopy in resecting submucous myomas with deep intramural invasion.
  
  
  METHODS
  Prospective, observational study (Canadian Task Force classification II-2).
  
  
  METHODS
  Department of gynecology at a general hospital.
  
  
  METHODS
  Sixteen women with a solitary submucous myoma, in which myometrial thickness between the outer edge of the myoma and inner edge of the serosa was between 5 and 10 mm.
  
  
  METHODS
  One-step hysteroscopic myomectomy.
  
  
  RESULTS
  Median myoma diameter and weight were 3.3 cm and 30 g, respectively. Myometrial thickness between the myoma and serosa increased gradually and significantly from 6.7 mm before, to 8.9 mm during, to 16.1 mm immediately after hysteroscopic myomectomy (p <0.001). The thickness of the opposite uterine wall increased from 10.1 mm before, to 11.4 mm during, to 18.8 mm after operation (p <0.001).
  
  
  CONCLUSIONS
  One-step hysteroscopic myomectomy may be performed to remove deeply infiltrating submucous myomas when myometrial thickness at the implantation site is as thin as 5 mm.
