- Brief summaryIn western countries, caesarean rates are rising. A caesarean section can cause a niche (defect at the site of the uterine scar).The incidence of niche related postmenstrual spotting in the Netherlands is expected to be 4100 per year. Promising results are reported after an innovative minimally invasive hysteroscopic resection of these niches. However its (cost) effectiveness in comparison to a control group has to be proven. Our primary objective is to study the effectiveness of hysteroscopic resection for niche related uterine bleeding disorders. Our secondary objective is to asses the quality of life, sexual function and cost-effective analysis will be made. The study is a multicentre randomized controlled trial. Patients will be randomly allocated to hysteroscopic resection or expectant management. Randomization will be performed centrally with the use of a permuted block design, stratified for recruiting centre. Women with post-menstrual uterine spotting and a niche with sufficient residual myometrium (at least 3mm) without any other intra-uterine disorders. Measurement with questionnaires will be performed at baseline, three and six months after randomization (control) or surgery (intervention). Cost-effectivity will be analysed at 12 months after randomization. Niche features will be measured by sonography at the baseline and after 3 months in both groups. At baseline a hysterosonography will be performed in all women to measure the niche and evaluate possible other causes of spotting in normal diagnostic workup. Prognostic dissimilarities will be registered, like previous therapies.
