Abstract
Objective: To evaluate the effect of hysteroscope diameter on the pain experienced by nulliparous patients undergoing diagnostic office hysteroscopy. Methods: One hundred nulliparous patients were randomly allocated in a 1:1 ratio to either the conventional office hysteroscopy group or the minihysteroscopy group.In conventional office hysteroscopy group, we used a rigid 2.9-mm hysteroscope with an outer sheath diameter of 5 mm. In minihysteroscopy group, we used a rigid 2.7-mm hysteroscope with an outer sheath diameter of 3.3 mm.The intensity of pain was measured using a 100-mm visual analog scale (VAS) during and 30 minutes after procedure. After the end of the procedure, the operators assessed the ease of the passage of the hysteroscope through cervical canal using a 100-mm VAS. Results: Patients in the mini-hysteroscopy group experienced less pain during the procedure [4.72±1.32 vs. 6.41±1.15, P value<0.001] .In contrast, pain scores 30 minutes after the procedure were comparable between both groups [1.83±0.92 vs. 1.59±1.04, P value =0.246]. The passage of the hysteroscope through cervical canal was easier in the mini-hysteroscopy group [48.86±17.81 vs. 60.74±21.3, P value =0.003]. Conclusion: The passage of the mini-hysteroscope through the cervical canal is easier than the passage of conventional office hysteroscope through the cervical canal. Moreover, mini-hysteroscopy is associated with less pain and discomfort compared with conventional office hysteroscopy
