Laparoscopic and robotic approaches for treatment of choledochal cysts in adults

Abstract

Background: While well-described for hepatic and pancreatic resection, the minimally invasive (MIS) approach in the treatment of choledochal cysts (CC) has been under-reported. Due to the technical complexity and steeper learning curve of minimally invasive biliary reconstruction, the MIS approach has not been as widely adopted in biliary surgery. We herein review the use of laparoscopic and robotic-assisted surgery in the treatment of CC. Methods: A comprehensive review of the literature was performed on the use of laparoscopic and robotic-assisted surgery in the treatment of CC. Results: Similar morbidity and mortality rates were noted among patients undergoing laparoscopic choledochal cyst resection (LCCR) compared with previous data from patients in the literature who had undergone an open approach (OCCR, open choledochal cyst resection); however, LCCR was associated with longer operative times and high conversion rates, largely attributable to the learning curve given the technically challenging nature of the procedure. The robotic platform (RCCR, robotic choledochal cyst resection) has been shown to offer an advantage in the hepaticojejunostomy anastomosis portion of CC resection vs. laparoscopy while providing comparable short-term outcomes compared with the LCCR approach. Conclusion: A minimally invasive approach to CC likely has improved perioperative outcomes with shorter LOS, return to baseline function, as well as improved cosmesis vs. OCCR. Longer operative times with minimally invasive approaches to CC have been attributed to steep learning curves, which have improved over time as surgeons become more facile with this technique. Both LCCR and RCCR have demonstrated similar rates of long-term postoperative complications and overall survival when compared to OCCR.
