Diagnostic and operative hysteroscopic procedures are performed to evaluate women with abnormal uterine bleeding structural uterine anomalies. Diagnostic and minimally invasive hysteroscopic surgical procedures in the hands of well-trained, experienced hysteroscopists offer little chance of serious complications. More extensive procedures offer greater risks, with fluid overload being the most common. The well-prepared and experienced hysteroscopic surgeon should have the ability, equipment, ancillary personnel, and facilities to prevent and to treat this problem, as well as the knowledge necessary to handle mechanical accidents, anesthetic complications, and post-procedure infections. The greatest risk in this procedure is, as always, an inadequately trained or ill-prepared operator.
