[The effect of the histological condition of the endometrium on fluid absorption during trans-cervical endometrium...

The aim of the study was to assess the effect of the number of endometrial and myometrial vessels on fluid absorption. Operative details and histology results (endometrium chips and myometrial biopsy) of fifty-four consecutive patients undergoing transcervical endometrial resection were analyzed. Thirteen of the 54 patients had hormonal pretreatment using 600 mg/day danazol (n = 11) or norethisterone 10 mg/day (n = 2) for four weeks before procedure. Simultaneous myomectomy were performed on 17 patients. A positive correlation was found between the number of endometrial vessels and volume of fluid absorption, although due to the small study population the result is not significant [p = 0.087, r = 0.29, CI (95%) for r: 0.218 to 0.377]. The correlation with myometrial vessels was found to be negative [p = 0.1, r = -0.39, CI (95%) for r: -0.527 to -0.262]. Patients with hormonal pretreatment absorbed less fluid, but not in a significant amount. Simultaneous myomectomy has no effect on absorption. There is only a poor correlation between fluid absorption during endometrial resection and the number of vessels in the endometrium and myometrium. The authors emphasize the importance of continuous monitoring of fluid dynamics.
