Objective To analyze the clinical value of hysteroscopy in the diagnosis and treatment of endometrial polyps. Methods Of 749 cases of abnormal uterine bleeding treated in our hospitals from July 2006 to March 2009,177 cases were suggested to be endometrial polyps in virginal B-ultrasonography and/or hysteroscopy. These patients with endometrial polyps underwent trartscervical resection of endometrium(TCRE)or trartscervical resection of polyp(TCRP),and the diagnostic effects between B-ultrasonography and hysteroscopy were compared. Results When compared with pathological diagnosis,the sensitivity of the diagnosis by B-ultrasonography and hysteroscopy were 65.6% and 96.0% respectively. The curative rate of abnormal uterine bleeding due to endometrial polyps was 95.2% by hysteroscopy. No complications occurred. Conclusion Hysteroscopic diagnosis of endometrial polyps is of high accuracy,good effect,minimal injury and low recurring rate. It's a good approach in the treatment of abnormal uterine bleeding resulted from endometrial polyps.
