The most common surgery for Gall stones is Laparoscopic Cholecystectomy where your surgeon removes the diseased Gall Bladder through small holes made on the abdomen. They are usually 4 in number. Your usual stay is 1 day or so in the hospital. SMILS/SILS is a recent form of Laparoscopic surgery where the surgery is done only through a single incision from the belly button. This is perticullary useful if you want to avoid any marks on the body. However, the post surgery pain may be similar or more than the conventional Laparoscopy. Open surgery is now reserved for instances where the surgeon is unable to proceed with laparoscopic surgery due to uncertain anatomy or problems concerned to operative safety. Sometimes the surgeon may take the decision to convert or do an open procedure as the Gall Bladder may look malignant on preopertaive scan.
