Assessment of the da Vinci Single Port Robotic Platform on Cholecystectomy in Adolescents.

The new da Vinci single port (SP) robotic platform has great appeal for pediatric surgery. To assess its efficacy and identify potential challenges, 7 adolescents underwent SP cholecystectomy. The surgeon controls three fully wristed elbowed instruments, and the first fully wristed da Vinci endoscope through a single 2.5 cm cannula. Instruments can reach 24 cm deep and triangulate distally. Instruments can also reach anatomy anywhere within 360° of port placement. A vertical incision was made through the umbilicus for port access. The cystic duct and cystic artery were dissected, clipped, divided, and hook cautery was used to remove the gallbladder. Patient characteristics and outcomes were collected and analyzed. Patients were American Society of Anesthesiologists (ASA) classes I, II, and III; mean age was 17 years; mean weight was 72 kg; and 6 of 7 patients were female. There were no fatalities, and there were no returns to the operating room. Mean estimated blood loss was 2 mL and mean case duration was 126 minutes. Five out of seven patients were treated as outpatients, and none of them required narcotics on discharge. One patient reported bilateral shoulder pain 1 day postoperatively and was taking hydrocodone/acetaminophen at the time of 13-day follow-up. SP robotic platform cholecystectomy in adolescents appears to be safe and effective. The wristed movement of the robotic instruments improves surgeon dexterity, and the single incision hidden in the contour of the umbilicus provides good cosmesis. This series sets an exciting precedent and provides a glimpse of what is possible in pediatric robotic surgery. Clinical Trial Registration number 2014-0396.
