Comparison Between Low Pressure Pneumoperitoneum with High Pressure Pneumoperitoneum in Post-operative Pain, Shoulder Tip Pain and Common Bile Duct Injuries in Patients Undergoing Laparoscopic Cholecystectomy

The incidence of pain and common bile duct injury in patients undergoing laparoscopic cholecystectomy using Low pressure pneumoperitoneum is less versus High pressure pneumoperitoneum.

Pain will accessed using VAS. Pain (VAS): The Visual Analogue Scale (VAS) measures pain intensity. The VAS consists of a 10cm line, with two end points representing 0 ('no pain') and 10 ('pain as bad as it could possibly be'). It was assessed at 4, 8, 12 hours post-operatively by using Visual Analogue Pain Scale. No pain \|0\_\_\_\_1\_\_\_\_2\_\_\_\_3\_\_\_\_4\_\_\_\_5\_\_\_\_6\_\_\_\_7\_\_\_\_8\_\_\_\_9\_\_\_\_10\| sever pain Mild pain-Moderate Pain-Sever pain Visual Analogue Pain Scale And CBD injury will be accessed using bismuth classification. CBD INJURY: Injury to CBD Is Classified According to Bismuth Classification: Type I is a low injury with a stump length more than 2 cm. Type II is a middle level injury with a stump length less than 2 cm. Type III is a high-level injury without common hepatic duct available but preserved confluence. Type IV involves loss of hepatic confluence with no communication between right and left ducts.
