Introduction

Cholecystectomy is the common operation of the biliary tract. During cholecystectomy cystic duct can be secured with the sutures or clips. Knot tying in open surgery can be easily be learned and performed.  However, knot tying becomes challenging and frustrating when performed laparoscopically. In laparoscopy there is lack of direct manual contact with tissue, therefore the sense of feel of tissue is restricted, secondly the image is transmitted to a two dimensional video screen & the laparoscope magnifies the image. This accentuates a person’s natural tremor and a two dimensional view eliminates true depth perception.[1]
