Clinical efficacy study of the IBS® (Intergrated Bigatti Shaver) Tissue Removal Device in the treatment of endometrial polyps.

Background: The IBS^® Tissue Removal Device, as a new technology, currently lacks a systematic evaluation of its effectiveness in treating endometrial polyps. Furthermore, the exact cause of polyps recurrence is not yet clear. The purpose of this article is to compare the efficacy of the IBS^® Tissue Removal Device with hysteroscopic cold knife resection for the treatment of endometrial polyps and analyze the recurrence factors of endometrial polyps.

Methods: 202 patients with endometrial polyps who were admitted to Changzhou Maternal and Child Health Care Hospital from January 2019 to December 2022 were included in the retrospective studies. Based on the surgical technique, these patients were categorized into two groups: the IBS group (n = 100) and the cold knife group (n = 102). Following surgery, both groups underwent a year of follow-up. Data from the perioperative period (operation time, intraoperative blood loss, intraoperative rehydration, intraoperative complications, length of hospital stay), follow-up data (postoperative endometrial thickness, postoperative vaginal bleeding time, complication rate, menstrual recovery time, pregnancy rate, and recurrence rate) and general clinical data (age, BMI(Body mass index, BMI), number of pregnancies or miscarriages, number of hysteroscopic operations, preoperative white blood cells, fasting blood glucose, polyp diameter) were compared between the two groups.

Results: The recurrence rate of the IBS group was 6% (6/100), which was lower than that of the cold knife group (14.7% (15/102), and the difference was statistically significant (P < 0.05). The operation time, intraoperative blood loss, and postoperative vaginal bleeding time in the IBS group were significantly lower than those in the cold knife group (P < 0.05), and the multivariate analysis of polyp recurrence showed that polyp diameter was closely related to postoperative recurrence (P < 0.05). The preoperative white blood cells and blood sugar levels have no association with the diameter of polyps. (P > 0.05). There was also no significant difference between IBS group and cold knife group in intraoperative rehydration, intraoperative complications and postoperative hospital stay, intermenstrual bleeding, recovery of menstruation and endometrial thickness and postoperative pregnancy between the IBS group and the cold knife group (P > 0.05).

Conclusion: The IBS^® Tissue Removal Device can reduce the recurrence rate of endometrial polyps after surgery, improve the perioperative indexes, and reduce the postoperative vaginal bleeding time, which is better than that of hysteroscopic cold knife resection.
