title: Transcervical needle biopsy of uterine myoma-like tumors using an automatic biopsy gun.
abstract: OBJECTIVE
  To describe a practical procedure of transcervical needle biopsy of uterine myoma-like tumors using an automatic biopsy gun and its potential risks.
  
  
  METHODS
  Description of new biopsy procedure.
  
  
  METHODS
  University teaching hospital.
  
  
  METHODS
  Three hundred twelve patients who had been recommended for surgery for uterine myoma-like tumors by the hospital's outside doctors.
  
  
  METHODS
  Transcervical needle biopsy of uterine myoma-like tumors.
  
  
  METHODS
  Successful sampling rate, duration of procedure, estimated blood loss, patient discomfort, and complications.
  
  
  RESULTS
  Of the 312 patients who underwent transcervical needle biopsy, specimens were obtained from 311 (99.7%). The mean (+/- SD) duration of procedure was 6.3 +/- 5.2 minutes. The mean estimated blood loss was 10.4 +/- 10.9 g. There were two cases (0.6%) in which the blood loss during the procedure was in excess of 50 g, but bleeding can be conservatively controlled in such cases with an intrauterine tamponade using gauze or a balloon catheter. The level of patient pain and discomfort during the needle biopsy was significantly lower than that during endometrial curettage. No major complications requiring surgery occurred.
  
  
  CONCLUSIONS
  Transcervical needle biopsies of uterine myoma-like tumors using an automatic biopsy gun are practical, simple, and safe. This new procedure can be of routine clinical use.
