Postoperative bleeding, though seldom enough to require repeat surgery
Prolonged suture pain, treated with pain medication or anti-inflammatory drugs
Injury to intra abdominal organs like the intestines, liver etc.
Fever, usually related to surgical wound infection
Intra-abdominal (within the abdominal wall) abscess
Blood clots can form in the legs due to inactivity after surgery
Blood clots can get dislodged from the legs and can get embedded in the lungs leading to respiratory distress
