Abstract
Transcervical resection of the endometrium (TCRE) is a first-line surgical treatment of abnormal uterine bleeding. However, many women experience unsuccessful results, causing hysterectomy in up 17% of cases. The aim of this study was to describe the odds of hysterectomy in women with abnormal uterine bleeding, treated with TCRE and levonorgestrel intrauterine contraceptive device (TCRE+LNG-IUCD) or TCRE alone. The secondary aim was to analyze the rate of amenorrhea. Designed as a retrospective cohort study, and conducted at Odense University Hospital, Denmark, the study included women with abnormal uterine bleeding, who underwent TCRE from January 2013 to December 2015. The decision of treatment with respect to LNG-IUCD was at the woman's discretion. Data were collected from medical records and a self-reported retrospective bleeding-pattern questionnaire. A multivariate regression model was used, enabling adjustment for potential and identified confounders. Out of 432 women, 276 (62%) consented to inclusion and of these, 16 (4%) were excluded. In total 88 (34%) received combined treatment and 172 (66%) received TCRE alone. Ten women (11%) treated with TCRE+LNG-IUCD underwent hysterectomy, compared with 27 (16%) treated with TCRE alone (OR=0.69, 95% CI 0.28-1.56; P=.34). Multivariate analysis disclosed a significant effect of TCRE+LNG-IUCD (OR=0.35, 95% CI 0.13-0.97; P=.04) on hysterectomy. The presence of fibromas was shown to increase the odds of treatment failure, resulting in hysterectomy (OR 2.69, 95% CI 1.15-6.31; P=.02). Furthermore, the incidence of amenorrhea was 59% in the TCRE+LNG-IUCD group and 36% in the TCRE alone group (OR=2.56, 95% CI 1.46-4.49; P<.01). The study showed significantly lower odds of hysterectomy in the TCRE+LNG-IUCD group when adjusted for confounders. Combination treatment improves the bleeding patterns significantly compared with monotherapy with TCRE.
