Thanks to advances in medicine the general dangers of surgical interventions such as thrombosis (the formation of blood clots and embolisms, blocked arteries from dislodged blood clots) have become rare. Nevertheless the extent of surgical intervention and the increased risk entailed have to be considered.
Wound infections, circulation and healing disorders leading to lengthy and painful inflammation as well as to necrosis, alterations in the shape of scars and the formation of disfiguring scars are extremely rare thanks to modern surgical techniques and highly effective antibiotics.  In the worst cases, subsequent operations and corrective measures are required.
Intolerance of the suture material with the consequences mentioned above cannot be foreseen and can also result in extensive post-operative treatment with possible further measures to correct excessive scarring. The formation of scars is highly individual, taking every form from fine lines to disfiguring and painful growths. The considerable length of the remaining scars and the tension on the scars, which may lead to the conditions listed above, should all be borne in mind.
Despite the care taken to stop bleeding, secondary bleeding may occur in the region of the operation. Surgical measures will have to be taken immediately to remove the haematoma.
Due to the large area of the wound and despite the insertion of drains, haematomas and the accumulation of tissue fluids (seroma) may necessitate lengthy post-operative treatment with punctures and compression bandages or even an operation. It may be necessary to wear a compression corset.
Throughout the entire site of the operation are nerves which are responsible for feeling in the abdomen, upper thigh, hips and buttocks. These may be temporarily or even permanently damaged by the operation, which can lead to some loss of sensation in this region.
Tension in body tissues due to the operation may be found to be unpleasant and painful at first, or even in the long term, and lead to problems with posture, which may require long-term intensive physiotherapy.
