Introduction

Laparoscopic cholecystectomy has now become one of the most widely performed surgeries worldwide.Variations in the origin, course, number, and branching pattern of the cystic artery can contribute to bile duct injury. While the majority of the literature emphasizes on achieving the critical view of safety and preventing bile duct injuries, considerably less attention has been given to the role of vascular anomalies as independent contributors to operative complexity. Given its global prevalence, even miniscule complication rates become significant.

Methods

We present six cases of laparoscopic cholecystectomies with vascular variations derived from a single surgeon’s private practice that directly influenced intraoperative decision-making. This series throws light on the various anatomically significant cystic arterial anomalies and methods to prevent intraoperative complications during laparoscopic cholecystectomy by reviewing the relevant literature present on the topic.

Results

Understanding the intricate relationships between the cystic artery, cystic veins, hilar plate, cystic plate, umbilical plate, Calot’s triangle, biliary system, and portal triad is critical for avoiding complications during laparoscopic cholecystectomy. Positional differences in relation to the cystic duct, atypical origin and differences in number of cystic arteries are frequently observed during laparoscopic procedures. The case series demonstrates a range of vascular anomalies, including aberrant cystic artery origin, a large arterial trunk supplying both the gallbladder and hepatic segments, a caterpillar hump within Calot’s triangle, aberrant fundal arterial branches arising from the hepatic hilum, and a large cystic vein within the gallbladder fossa. Surgeons can maintain a low complication rate during the procedure by utilising techniques like B-SAFE, laparoscopic ultrasound, indocyanin green to identify relevant landmarks. Judicious use of cautery, proper illumination, visualization of the surgical field and avoiding distressed clipping if bleeding occurs, helps prevent vascular injury which in turn prevents a biliary mishap.

Conclusion

This study reiterates certain guidelines that aid in preventing vasculobiliary mishaps during laparoscopic cholecystectomy. It provides a peek into a senior surgeon’s point of view when presented with intraoperative scenarios not encountered in a textbook. This report helps start a conversation on a lesser talked about, yet important aspect of a widely performed procedure and thus aims to improve surgical outcomes.
