Conventional SILS vs Harmonic Scalpel SILS
Single incision laparoscopic cholecystectomy is gaining widespread acceptance. there are some

 The use of harmonic scalpel may aid in solving some of these issues that may allow
 simplification of the technique. The investigators will compare the ordinary method of single
