BACKGROUND: Lap cholecystectomy is gold standard for cholelithiasis. Earlier the incidence of
morbidity and mortality was higher. Later on with the understanding of anatomy and fine techniques
both morbidity and mortality decreased. Understanding of the anatomy of calot’s triangle reduces the
complications of the procedure.
OBJECTIVE: To study the pattern of variations in cystic artery and comparison with Caucasians.
MATERIAL AND METHODS: All laparoscopic cholecystectomies performed in Shah Medical
Centre,over a period of 1 year from January 2013 to December 2013,in whom detailed anatomy of
calot’s triangle was clearly displayed were included in the study. Those laparoscopic cholecystectomies
in whom the detailed anatomy was not clear were excluded from the study.
Laparoscopic cholecystectomies were performed under general anesthesia. The anatomy of cystic artery
and its branches were identified, and it was also correlated in relation to cystic duct and common hepatic
duct.We performed 240 lap cholecystectomies over a period of 1 year from January 2013 to December 2013.
RESULTS: The pattern of cystic artery was studied in 240 laparoscopic procedures. Origin of cystic
artery from right hepatic artery was observed in 82% cases. Double cystic arteries were observed in 8%
cases. Common hepatic artery gave rise to 6% cystic arteries. Cystic arteries originated from
gastroduodenal artery in 3% cases. Hepatic parenchyma gave rise to 2% cases.
CONCLUSION: Percentage of variations in cystic artery as compared to Caucasians are not different in
our study.These variations should be kept in mind to reduce complications.
