Aim: In laparoscopic surgery, knowing the anatomic variations helps being ready for any possibilities. In this study, the positions of the Calot`s triangle, and a. cystica and ductus cysticus in relation to each other were evaluated in people from the area who underwent laparoscopic cholecystectomy, and frequency of variation was reviewed.
Materials and Methods: In our study, the operation images of 100 patients who underwent laparoscopic cholecystectomy in the General Surgery Clinic at the Medical Faculty of Trakya University were monitored and the anatomy of Calot`s triangle was evaluated.
Results: In 82% of our cases, the a. cystica was observed as a single branch in the Calot`s triangle, whereas two aa. cysticae were clipped in 12% of the cases. In 2 cases, a. hepatica dextra in the Calot`s triangle was observed very close to the gallbladder serosa, and there was a very short a. cystica. In one case, a. cystica first passed to the posterior aspect of ductus cysticus and formed a curve at the lower portion of ductus cysticus, then turned to the anterior aspect of the duct, and continued to the gallbladder serosa from the neck part. In 3 cases in this study, a. cystica moved in a caudal direction and was parallel to ductus cysticus, then entered the bladder.
Conclusion: In brief, the anatomy of the Calot`s triangle, which acts as a key point in laparoscopic cholecystectomy, varies much. A good understanding of the anomalies of a. cystica in laparoscopic cholecystectomies is important in order to prevent possible complications.
