There is a risk of bleeding from the staple line with the chances of it happening less than 1%, and in case it happens it can be managed without the need for further operation (a Blood transfusion) and settles down itself. In some very rare instances patients were taken back to the operation theatre for another laparoscopic procedure to drain out any blood from the abdominal cavity.
It is my policy that if i am unhappy with your post operative recovery, i will take you back to the operation theatre for a laparoscopy. This may mean that you have a 2nd procedure, which shows no abnormality. However studies have shown that early intervention for complications produces the best outcomes.
