Retrospective cohort study on the symptomatic recurrence pattern after hysteroscopic polypectomy

Abstract

Objectives: The recurrence rate of benign endometrial polyps after a hysteroscopic polypectomy is low, between 0% and 15%. There are limited follow-up duration data on recurrence factors for benign polyps after hysteroscopic polypectomy, including recurrences with Versapoint® versus resectoscope. This study aims to estimate the rate of symptomatic recurrence following hysteroscopic polypectomy and to analyze the possible risk factors involved with Versapoint® versus resectoscope. Materials and Methods: We designed a retrospective cohort study in a tertiary university hospital in Seville (Spain) which looked at the results of polypectomy with a 9-mm resectoscope on 42 women between 2008 and 2015 compared to 151 women using Versapoint® during 2014. Results: The rate of first recurrence was 24.35%. There was a strong positive correlation between the recurrence and the follow-up duration (odds ratio [OR] = 2.58; 95% confidence interval [CI] = 1.68-5.04; P = 0.000), the polyps causing abnormal uterine bleeding (OR = 2.5; 95% CI: 1.1-3; P = 0.04), and a polyp size >15 mm (OR = 1.63; 95% CI = 1.3-3.1; P = 0.02). There were no statistical differences in polyps' recurrence among the types of hysteroscopic polypectomy (P > 0.05). Conclusion: The main risk factors for recurrence were polyps causing abnormal uterine bleeding, size, and follow-up duration.
