A safety and feasibility study of Manual Vacuum Aspiration for Endometrial Polyp- like Lesions; A case series

Study Objective: We conducted a clinical evaluation of safety and feasibility of manual vacuum aspiration (MVA) for the removal of endometrial polyp-like lesions. Design: Prospective study (case series) Setting and Participants: This study included patients at our hospital who were suspected of having endometrial polypoid lesions based on ultrasound findings and who provided informed consent. Resectoscope (26Fr rigid hysteroscopy) was performed to examine the uterine cavity and identify polypoid lesions. The endometrial tissue, including polyp-like lesions, was aspirated using the MVA system, immediately followed by a resectoscope to detect any residual tissue. This study was conducted with the approval of the hospital’s institutional review board. Interventions: For each enrolled patient, clinical data were collected. Results: A total of 29 patients were enrolled. Complete resection was achieved in 25 cases (86.2%), whereas 4 cases (13.8%) with larger lesions required resectoscope for complete removal. The number of aspirations in cases of complete resection ranged from 1 to 3, whereas no complications were observed. The lesions that could not be completely resected exceeded 20 mm in size and consisted of thick stalks. Conclusion: The use of MVA for the removal of endometrial polyp-like lesions is easy and safe, similar to its use in miscarriage and abortion procedures. Therefore, excluding particularly large polyps, MVA is a viable option for the removal of endometrial polyp-like lesions, without the need to purchase new, expensive equipment.
