Pregnancy rates following endometrial polyp removal: A comparison of resectoscopes and the Lin polyp snare system

Introduction: Endometrial polyps can cause infertility and their removal is recommended. Transcervical resection (TCR), which is commonly selected, is performed using a resectoscope under anesthesia. Recently, use of the Lin snare system (Snare) has been reported for polyp removal without anesthesia. Snare uses a diagnostic flexible hysteroscope with an outer diameter of 3.1 mm. However, the effects on infertility are unclear. We investigated infertile patients with endometrial polyps at our hospital and compared pregnancy rates based on the two different methods. Materials and Methods: Between January 2008 and April 2014, we analyzed 64 patients who were postoperatively followed-up for at least 12 months. The patient backgrounds and pregnancy rates were investigated retrospectively for both groups. TCR was performed under general anesthesia, with hospitalization. Snare was used with no anesthesia and no cervical dilatation on an outpatient basis. Since the introduction of Snare at our hospital in 2012, it has been the first
