Objective: To evaluate the indications, intraoperative diagnoses, and complication rates of both diagnostic and operative hysteroscopic procedures. Materials and Methods: Five thousand four hundred seventy-four (5474) hysteroscopic procedures performed in the department of gynecologic endoscopy unit between May 2005 and December 2012 were retrospectively analyzed from the archives. Indications, intraoperative diagnosis, and complications of all gynecological endoscopic procedures are recorded. Results: Abnormal uterine bleeding in premenopausal and postmenopausal women was the most frequent indication for diagnostic hysteroscopies in 1,887 (40%) cases. The most common preoperative indication for operative hysteroscopy was endometrial polyps in 469 (55.7%) cases and submucous leiomyomas in 151 (17.9%) cases. In this series, the most common complication was uterine perforation which occured in 15 (0.27%) out of 5,474 cases and the rate for diagnostic hysteroscopy and operative hysteroscopy was 0.06% and 1%, respectively. Conclusion: Hysteroscopy is a safe and effective minimally invasive procedure with very low complication rate.
