Robot-assisted resection of choledochal cysts and hepaticojejunostomy in children less than 10 kg.

Objective: Laparoscopic resection of choledochal cysts and hepaticojejunostomy have been described in children since 1995, but these can be technically demanding procedures. Robotic surgical systems can facilitate complex minimal-access procedures. In 2009, we made the transition from conventional laparoscopic to robotic-assisted choledochal cyst excision with hepaticojejunostomy. We present our experience in children weighing less than 10 kg.

Methods: During 2009, 5 children weighing less than 10 kg underwent robotic resections of choledochal cysts and hepaticojejunostomy using the da Vinci surgical system. The Roux loop was fashioned extracorporeally. Mean age was 1 year (range, 0.5-1.4), and mean weight was 8.5 kg (range, 7.6-9.5). All 5 had type 1c cysts, and 3 were very large.

Results: All 5 cases were treated successfully by robotic resection of the cyst and hepaticojejunostomy. Feeding was established by a median of 4 days (range, 3-6), and patients were discharged after a median of 6 days (range, 5-7) with no postoperative complications.

Conclusions: The technique is safe and effective in children weighing less than 10 kg. The authors found ergonomic advantages in using robotic-assisted surgery for this complex minimal-access procedure.
