A laparotomy is a surgical procedure involving a large incision through the abdominal wall to gain access into the abdominal cavity. It is also known as a celiotomy. The first successful laparotomy was performed without anesthesia by Ephraim McDowell in 1809 in Danville, Kentucky.
Laparoscopic cholecystectomy is the most common laparoscopic procedure performed. In this procedure, 5â10 mm diameter instruments (graspers, scissors, clip applier) can be introduced by the surgeon into the abdomen through trocars (hollow tubes with a seal to keep the CO2 from leaking).
