Utilization of a Single-Site Port as an Adjunct for Multi-Port Robotic-Assisted Surgery in Children.

Introduction: The focused use of a single-site port as an adjunct designed to decrease overall port site number and/or assist with specimen extraction in pediatric robotic surgery has not been fully elucidated. We aimed to describe the feasibility of using the single-site port as an adjunct during multi-port robotic-assisted minimally invasive surgery (RA-MIS). Methods: A single institution retrospective review of pediatric patients who underwent multiport RA-MIS with an adjunctive single-site (SS) port from August 2018 to October 2022 was performed. Demographic, perioperative, and postoperative variables were collected; descriptive analysis was performed. Results: A total of 13 patients were included; 46% were female, and 47% were Caucasian. Median age at surgery was 14.9 years of age (interquartile range [IQR] 10.6, 18); median weight was 61.1 kg (IQR 39.7, 73.6). Eleven patients (85%) underwent splenectomy; 2 patients (15%) underwent adrenalectomy. Four patients had a combined procedure (SS cholecystectomy with multi-port splenectomy [n = 3], multi-port bilateral adrenalectomy [n = 1]). The median total operative time was 197 minutes (IQR 131, 316); median console time was 59 minutes (IQR 40, 126). Two 8 mm robotic ports were utilized for all but 1 patient who required a third 8 mm port. The median length of stay was 2.1 days (IQR 2.0, 3.1). One readmission for fever occurred following a combined cholecystectomy/splenectomy. No hernias or wound infections were identified at the single-site port. Conclusion: Use of a SS port as an adjunct is a feasible option and should be considered for those with splenomegaly or need for combined procedures in different quadrants of the abdomen.
