摘要

Background

This study aimed to evaluate the safety and feasibility of manual vacuum aspiration (MVA) for the removal of endometrial polyp-like lesions, an approach potentially simpler and less resource-intensive than conventional hysteroscopic techniques.

Methods

We conducted a prospective case series including 29 patients with suspected endometrial polypoid lesions based on ultrasound findings. After informed consent, transcervical resection (TCR) using a 26Fr rigid resectoscope was performed to visualize the uterine cavity. MVA was then applied to aspirate the endometrial tissue, including polyp-like lesions, immediately followed by TCR to check for residual tissue. Clinical data were collected for each patient, and the study was approved by the institutional review board.

Results

Complete removal by MVA alone was achieved in 25 of 29 patients (86.2%). In 4 cases (13.8%) with lesions > 20 mm and thick stalks, additional TCR was required for complete resection. The number of aspirations in complete cases ranged from 1 to 3. No perioperative complications occurred.

Conclusions

MVA is a safe, simple, and cost-effective technique for removing small-to-moderate endometrial polyp-like lesions. Except for particularly large polyps, MVA may represent a viable alternative to hysteroscopic resection, reducing the need for specialized equipment.
