The investigators will compare between clipping and ligation of the cystic duct and the cystic artery in Laparoscopic cholecystectomy. This is the main question that will be discussed in the review.

cholecystectomy is the second most commonly intra-abdominal operation worldwide after Appendectomy. In standard surgery ,there are increase incidence of wound infection,bleeding , discomfort and hospital stay so laparoscopic surgery has become the best choice for treatment of symptomatic and uncomplicated Gall bladder stones and hernia repair.

Once laparoscopic cholecystectomy emerged controversies persist with regard to the best method to ligate the cystic duct and artery. They may be ligated by separate and multiple ligatures by absorbable suture material, or using absorbable clips.

Suture ligation of cystic duct appeared to be more cost effective.On the other hand, the application of clips shown to have some drawbacks such as dislodgement and bile leakage and increase liability of long term clip migration which resulted in biliary stone formation or bile duct stenosis and also they are expensive .Another complication of clips that they may ulcerated through the duodenum.

Ligation takes more time than applying a clip, and it needs well training, but it is feasible, cost- effective and safe alternative method to secure cystic duct and artery in laparoscopic cholecystectomy.

The Aim of this study is to compare the two different methods; Tie versus clipping, for securing cystic duct and artery in laparoscopic cholecystectomy. In terms of efficacy and safety, and also the difference in the times of operations in both methods
