Comparison of Da Vinci Robotic-Assisted with Open Kasai Portoenterostomy for Biliary Atresia.

BACKGROUND

Robotic-assisted Kasai portoenterostomy (RAKPE) has been used to treat biliary atresia (BA). This study aimed to compare the efficacy of RAKPE and open Kasai portoenterostomy (OKPE) for BA.

METHODS

Thirty-one children with type III BA who underwent surgical treatment in two centers from January 2022 to December 2023 were retrospectively collected. According to the operative techniques, the participants were divided into the RAKPE group (13 cases) and the OKPE group (18 cases). The operative time, jaundice clearance (JC) rate, and incidence of cholangitis were analyzed.

RESULTS

The operative time in the RAKPE group (204.3 ± 19.9 min) was significantly longer than that in the OKPE group (186.2 ± 22.2 min), P < 0.05. However, the blood loss (8.1 ± 2.5 ml) in the RAKPE group was significantly decreased compared with the OKPE group (13.6 ± 4.8 ml), and 15.4% patient need blood transfusion in RAKEP group was litter than that 55.6% in the OKPE group, P < 0.05. The time to oral feeding (2.8 ± 0.4 days vs. 4.3 ± 0.7 days) and the time to pass ICG-positive stools (3.6 ± 0.6 days vs. 4.7 ± 0.9 days) in the RAKPE group were significantly shorter than those in the OKPE group, P < 0.05. No significant differences were observed in the bile excretion rate, hospital stay time, and JC rate. The incidence of cholangitis in the RAKPE group was significantly lower than that in the OKPE group during short follow-up.

CONCLUSION

RAKPE may be associated with lower intraoperative blood loss, decrease need for postoperative transfusions and decreased rate of postoperative cholangitis compared to OKPE.

LEVEL OF EVIDENCE: III.
