Arms Assigned Interventions
Active Comparator: SILS Cholecystectomy
Single Incision Laparoscopic Cholecystectomy
Procedure: SILS
Single Incision Laparoscopic Cholecystectomy
Active Comparator: Standard Laparoscopic Cholecystectomy
4 port laparoscopic cholecystectomy
Procedure: Standard Laparoscopic Cholecystectomy
4 port technique
Other Name: Laparoscopic Cholecystectomy

Detailed Description:

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.
