Ultrasound-Guided Polypectomy: Evaluation of a Novel Technique to Remove Endometrial Polyps in the Office

To present a novel technique for office resection of pedunculated endometrial polyps under ultrasound guidance.

A prospective trial was conducted at an academic center where women with abnormal uterine bleeding (AUB) who were diagnosed an endometrial polyp following saline infusion sonogram (SIS), were offered polyp removal under ultrasound guidance using a universal grasping forceps (2.5 mm × 25 cm). The primary outcome was to evaluate the feasibility of this technique for complete removal of the polyp. The secondary outcomes were to evaluate the patients' pain score, satisfaction score using visual analogue score (VAS), and efficacy of the technique in alleviating symptoms in patients with AUB due to polyps.

Thirty patients participated, with a mean age of 54.8 ± 11 years. Average polyp volume was 1.87 cm³ and mean duration for polypectomy was 11 minutes 31 seconds. The median pain score immediately post-procedure was 5 (0-9). We were unable to complete the procedure in two patients due to patient discomfort and poor visualization. Complete removal of polyp was ensured by checking for a thin endometrial echo at the end of the procedure and by performing SIS at 3-months post-procedure. Of the 22 patients who returned for follow-up, 19 (86.36%) showed no evidence of polyp on SIS and all reported resolution of AUB symptoms. The median satisfaction score at the follow-up was 10/10. Adequate pathology samples were obtained from all cases, diagnosing malignancy in one and endometrial hyperplasia in one patient.

This technique offers safe and effective removal of pedunculated endometrial polyps in an office setting, avoiding the need for general anesthesia. It can be offered as a therapeutic option at the initial point of contact, providing symptom relief and tissue diagnosis while reducing costs and patient visits.
