Assess the prevalence and severity of the various complications of operative hysteroscopy, the context in which they occur and the treatments proposed.A single-center observational study from 1/1/90 to 1/1/99 including 2,116 surgical hysteroscopies (resection of a fibroma (782) or polyp (422), section of a septate uterus (199), synechia uteri (90) and endometrectomy (623)).There were 74 complications (3.5%). The most frequent was uterine perforation (34 cases (1.61%)). There were 13 cases of haemorrhage (0.61%), 16 cases of post-surgical fever (0.76%) and 11 metabolic complications (0.47%). Synechia uteri was the surgical intervention with the greatest risk of complications.The complications of surgical hysteroscopy are rare and relatively benign. Uterine perforation appears to predominate. In our study, the risk of complication was enhanced in the case of synechia uteri.
