Objective:
To describe a practical procedure of transcervical needle biopsy of uterine myoma-like tumors using an automatic biopsy gun and its potential risks.
Design:
Description of new biopsy procedure.
Setting:
University teaching hospital.
Patient(S):
Three hundred twelve patients who had been recommended for surgery for uterine myoma-like tumors by the hospital's outside doctors.
Intervention(S):
Transcervical needle biopsy of uterine myoma-like tumors.
Main Outcome Measure(S):
Successful sampling rate, duration of procedure, estimated blood loss, patient discomfort, and complications.
Result(S):
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.
Conclusion(S):
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.
