A Comparison of Long Term Outcomes Following Total Laparoscopic Hysterectomy and Laparoscopic Supracervical Hysterectomy.
Sample: 62 consecutive premenopausal women referred to the department for hysterectomy on
the basis of a benign condition. The expected mean pain reduction (m) in the LSH group:
3.32, sd (s): 2.71.24 A difference in mean pain reduction (d) equal to 1 sd is considered a
clinically important improvement (standardised difference d/s=1). Number of women required
(power 90 % and a level of significance 0.05): 62 patients.
Methods: The study participants are randomised to total laparoscopic hysterectomy (n = 31),
or laparoscopic supracervical hysterectomy (n = 31).
Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator), Primary Purpose: Treatment
Pelvic pain reduction after the procedure. Occurrence and intensity of pelvic pain after the procedure.
10-point visual analogue scale. Values are given as median (range), mean (sd) or n (%).
