Clinical application of manual hysteroscopic tissue retrieval system (HTRS) PolyGone in treating endometrial polyps (EPs) outpatient

Abstract

Objective:To investigate the safety and effectiveness of manual hysteroscopic tissue retrieval system (HTRS) PolyGone in outpatient treatment of endometrial polyps (EPs). Materials and methods: : A total of 32 patients undergoing outpatient endometrial polyp surgery with PolyGone manual HTRS from August 2021 to December 2021 in the Third Xiangya Hospital of Central South university were selected as the research objects. Results:All 32 patients successfully completed the surgery, the average surgery time was 12.06±6.62min, the average resection time was 2.98±2.12min, the dilation fluid volume was 229.69±109.76ml, and no serious complications occurred. The median visual analogue scale(VAS) score of patients at 0.5h after operation was 2 (0,2), and that of patients at 2h after operation was 0 (0, 2). The LIKERT five-scale score of both patients and doctors showed 100% satisfaction. All patients were diagnosed as EPs by postoperative pathological examination and were followed up one month after surgery. The duration of postoperative vaginal bleeding was 2-9 days, with a median of 5 (4,7). There was little vaginal bleeding and no postoperative complications. Pregnancy was found in 4 patients 3 months after operation. Among the 28 patients who were not pregnant, 22 (91.7%) of the 24 patients with abnormal vaginal bleeding symptoms before operation disappeared, and the other 2 patients had a little irregular vaginal bleeding after Mirena implantation, which was considered to be caused by Mirena. 26 patients completed B-ultrasound review within the follicular period 3 months after surgery, 23 patients (88.5%) had normal results and no recurrence of polyps,1（3.8%）patient had uneven endometrium, and the other 2 (7.7%) patients were suggested to consider polyp recurrence (none of them received postoperative adjuvant medication). Conclusion: The manual HTRS PolyGone is safe, effective and has high patient satisfaction. It is a new option for non-electrothermal resection of EPs.
