General surgery involves the performance of surgical procedures - manually and with the aid of instruments - on patients who suffer from diseases and trauma.Gastrointestinal surgery specifically deals with the organs of the digestive system, which extends from the oesophagus to the anus and includes the stomach, pancreas, liver, gallbladder, small intestine, colon and rectum. It also consists of the management of disorders and pathologies of the abdominal wall such as hernias and eventrations.In order for the surgery to be more comfortable for the patient, it is preferably performed by laparoscopy which allows for mini-invasive approaches.
