Arterial Anatomy in Calot’s Triangle as Viewed through the Laparoscope

Abstract

The arterial anatomy in the Calot’s triangle as seen during the laparoscopic dissection while performing laparoscopic cholecystectomy is quite different to what has been taught traditionally. The difference is easily visible and recorded because the image on the monitor during laparoscopy is 14 times the normal size, therefore, even very small abnormalities can be recognised with ease. The anatomy of Cystic artery was reviewed on four hundred consecutive laparoscopic dissections of Calot’s triangle during laparoscopic cholecystectomies between December 1996 to December 2000 and it was noted that, the normal cystic artery was found in 66 percent cases. The most common abnormality was branching of cystic artery into a superficial and a deep) branch, [20% cascs.1 A double or an accessory cystic artery [9% cases]. Cystic artery crossing in front of the common hepatic duct [4%] cases. Caterpillar hump or recurrent right hepatic artery in [1 percent] which infact is the most significant surgical abnormality.
