Increasing intraluminal pressures eventually exceed capillary perfusion pressure, which is associated with obstructed lymphatic and venous drainage and allows bacterial and inflammatory fluid invasion...
Lap Appendectomy in Acute Appendicitis
The role of laparoscopic appendectomy is still not well defined in the literature. Laparoscopic appendectomy is feasible in developing countries with similar postoperative outcome and less requirement...
Biliary Stent Removal
Laparoscopic common bile duct exploration (LCBDE) has been found to be a safe, efficient and cost-effective treatment for choledocholithiasis. Following LCBDE, the clearance may be ascertained by a cholangiogram...
