Administration of rectal cytotec versus rectal buscopan before hysteroscopy

Abstract

Introduction Our objective was to compare the effect of rectal misoprostol (Cytotec) versus rectal hyoscine-n-butyl bromide (Buscopan) on patients undergoing hysteroscopy. We hypothesised that HBB may have a role in cervical priming. Material and methods This trial was conducted at Bezmialem Vakif University Hospital. Women of reproductive age between 18–50 years who were scheduled for operative hysteroscopy indicated by type 1 submucous myoma or endometrial polyps were recruited for the study. Ninety patients were divided randomly into three groups. Group 1 received placebo treatment. Group 2 received rectal 200 mcg misoprostol and Group 3 received rectal 20 mg hyoscine-n-butyl bromide two hours before the procedure. Procedures were performed using a bipolar 26 F (9 mm) continuous-flow rigid resectoscope with a 30° lens. The outcome measures included cervical dilation width and time, ease of cervical dilation, procedure time and operative complications. Postoperative self-rated pain was assessed one hour after the procedure. Results Thirteen patients (43. 3%) in the placebo treatment group, 11 patients (36.7%) in the misoprostol group and four patients (13.3%) in the hyoscine-n-butyl bromide group needed analgesics postoperatively (p = .02). The mean duration of cervical dilation time was longest in Group 1 and shortest in Group 3, however this difference did not reach statistical significance (p=.11). There was no difference with regard to other studied parameters. Summary HBB reduced the need for pain medication compared to placebo. Larger studies are needed to further investigate the role of HBB in facilitating pre-operative cervical priming.
