Abstract
This study compares the clinical efficacy and safety of a thermal uterine balloon system with hysteroscopic endometrial resection in the treatment of dysfunctional uterine bleeding. In all, 147 women were treated by two experienced gynaecological surgeons: one performed 73 thermal balloon ablations and the other 74 endometrial resections between November 1994 and April 1998. The inclusion criteria were similar in both groups. The operative time was reduced significantly with the uterine balloon technique. There were no intra-operative complications in either group and postoperative morbidities were minimal and not statistically different. Multivariate analysis noted two prognostic factors associated with failures: retroverted uterus with thermal balloon ablation and age under 43 years with endometrial resection. The overall success rate did not differ significantly between the two groups 83.0 ± 5% for balloon ablation and 76.3 ± 6% for endometrial resection. Uterine balloon ablation appears to be as efficacious as endometrial resection. The former is much easier to perform, making the technique readily reproducible, especially by those with limited expertise in hysteroscopic surgery, and thus more widely applicable and safer.
