The objective of this chapter is to highlight the complications of hysteroscopic surgery. Hysteroscopy is considered a minimally invasive procedure with low incidence of complications, when implemented properly for the right indications in patients with better experience of the operating surgeons. Potential complications should always be taken into account and can be categorized into intraoperative complications and postoperative complications. Intraoperative complications which may arise during the hysteroscopy operations, may include anesthesia complications and traumatic complications. Air embolism, fluid overload syndrome, and thermal damage are the complications of distension media. Postoperative complications are statistically less common, but more pernicious as they affect patients away from hospital, given that majority of hysteroscopic operations are performed in outpatient setting.
