Importancia de la vena cística en la colecistectomía laparoscópica

Aim: There are differences in the description of the cystic vein in the literature, often without considering it an important element. We consider it vital to describe the presence of the cystic vein as a significant element that can disturb the critical view of safety during cholecystectomies, and also cause mistakes. Materials and Method: Between January 1, 2014 and December 31, 2018, the presence of the cystic vein during the dissection of the cystohepatic triangle in cholecystectomies was evaluated. Results: 397 laparoscopic cholecystectomies were performed, in 30 cases additional elements were evidenced in the cystohepatic triangle, which required a careful dissection, which after following its path and when evaluating other anatomical repairs such as the Rouvière sulcus and the visualization of the biliary tract, it was considered due to its characteristics that it was a cystic vein in 8 cases (2%). Discussion: The cystic vein is an anatomical structure whose existence must be kept in mind by the surgeon who performs laparoscopic cholecystectomy, because it can appear as a significant element altering the critical view of safety. Although in our series as a significant element it is 2%, other series describe it with a much higher frequency. Conclusion: It is necessary to carry out more studies on the presence and importance as an anatomical repair due to its value to prevent bile duct injuries and as a factor of confusion in the critical safety view.
