Examining the Effectiveness of Critical View of Safety (CVS) in Preventing Bile Duct Injuries During Laparoscopic Cholecystectomy

Abstract

Backgroud: Gallbladder diseases typically present as gallstones, inflammation, and cancer. Cholecystectomy has long been the established surgical approach for treating cholelithiasis and cholecystitis. The Critical View of Safety (CVS) technique is employed to identify key anatomical structures precisely, namely the cystic duct and the cystic artery. As such, this study aims to evaluate the effectiveness of the CVS method in laparoscopic cholecystectomy for preventing bile duct injuries. Material and methods: The study encompassed a cohort of 70 consecutive patients diagnosed with gallbladder disease. Thorough demographic information for each patient was meticulously collected. Preoperatively, a comprehensive hematological and biochemical profile analysis was conducted. Proficient and seasoned surgeons executed all surgical procedures. Subsequently, a post-operative evaluation was carried out for all patients. Results: In our study, aberrant anatomy was identified in two patients, while 68 patients exhibited typical anatomical structures. Notably, we achieved a 100 percent success rate in obtaining the Critical View of Safety for all patients in our study. However, aberrant anatomy was encountered exclusively in those two cases, necessitating a conversion to open cholecystectomy. Conclusion: The Critical View of Safety method for ductal identification is an effective technique.
