The aim of this paper is to review and to analyze the results of previous studies dealing with hysteroscopic treatment of postcesarean scar defects. A systematic review of publications indexed in MEDLINE/PubMed database identified a total of 11 studies dealing with resectoscopic treatment of postcesarean scar defect. The review was conducted in line with the Meta-analysis of Observational Studies in Epidemiology (MOOSE) guidelines and the PRISMA statement. In only few studies, patients were qualified for hysteroscopic surgery based on the measurement of the defect depth and thickness of residual myometrium above the pouch. Two principal techniques were used for the hysteroscopic treatment: resection of one edge of the scar diverticulum, and resection of the inferior and superior edges of the defect. Additionally, most authors performed electrocauterization of the niche bottom. Resectoscopic treatment turned out to be highly effective in the case of women with AUB. No complications of the hysteroscopic procedure have been reported. Methodological value of the reviewed studies was relatively low due to non-unified selection/verification criteria and incomplete, non-systematic postoperative assessment. In conclusion, hysteroscopic treatment seems to be a promising option in the management of postcesarean scar defects, but still further research is needed on the problem in question.
