The words “laparoscopic” and “open” appendectomy describes the techniques a surgeon uses to gain access to the internal surgery site. Most laparoscopic appendectomies start the same way. Using a cannula (a narrow tube-like instrument), the surgeon enters the abdomen. A laparoscope (a tiny telescope connected to a video camera) is inserted through a cannula, giving the surgeon a magnified view of the patient’s internal organs on a television monitor. Several other cannulas are inserted to allow the surgeon to work inside and remove the appendix. The entire procedure may be completed through the cannulas or by lengthening one of the small cannula incisions. A drain may be placed during the procedure. This will be removed later by your surgeon.
