The risks associated with a laparotomy are greater than those associated with a laparoscopy but they are still fairly low. Most of the complications are relatively minor and they usually resolve themselves fairly quickly.
The complications which may occur at the time of surgery include an allergic reaction to the anaesthetic, uncontrolled bleeding and accidental damage to internal organs such as the bowel or bladder.
Complications which may develop after the operation while you are still in hospital include constipation, bleeding at the wound site, urinary infection, wound infection, chest infection, heavy vaginal bleeding, difficulty emptying the bladder, and thrombosis (when a blood clot forms in a vein, usually in the pelvis or a leg) and embolism (when a blood clot lodges in the lung).
Complications which may develop after you return home include wound infection, bleeding from the wound, urinary infection, a vaginal discharge with an unpleasant odour and a change in bladder and/or bowel function which may persist for one to two months.
