Single Incision Laparoscopic Surgery (SILS) Versus Laparoscopic Cholecystectomy
Single Incision Laparoscopic Surgery (SILS) Versus Laparoscopic Cholecystectomy
Prospective randomized trial of single incision versus standard 4 port laparoscopic
 cholecystectomy. Hypothesis is that the operative time will be longer with single incision.
This will be a prospective, randomized clinical trial involving patients who present to the
 hospital with an indication for cholecystectomy. We will offer enrollment to several
 institutions provided they receive institutional approval.

 This will be a definitive trial design. Based on our operative times with SILS compared with
 our recent experience in standard laparoscopy, a sample size of 60 patients will give us a
 power of 0.8 with an α of 0.05.

 After the procedure, both groups will be managed in the same manner per routine care. They
 will be discharged when tolerating a regular diet and their pain is well-controlled on oral
 pain medication.
