Port-site complications after pediatric urologic robotic surgery

The incidence of port-site hernia development after adult laparoscopic surgery is reported to be between 0.1% and 3.0%. There are no published reports concerning hernia incidence or related factors after pediatric urologic laparoscopic interventions. We present our experience with port-site complications following pediatric urologic robotic surgery (PURS). From July 2005 to June 2009 we prospectively followed the first 200 PURS cases performed at Children's Hospital of Philadelphia. All cases had follow-up available for at least 2 months postoperatively. The data collected allowed for evaluation of the outcomes for each port site separately and compared its size, location, and fascial closure status. Median age was 3.2 years (0.4-18.8 years). All 200 patients had follow-up with median of 11 months (0.2-83.4 months). There were 600 port sites analyzed in the 200 cases. Of the 600 port sites, 200 were umbilical. The other 400 port sites were lateral to the rectus muscle, either subcostal or at the level of the anterior superior iliac spine. There was no wound irrigation prior to closure on any sites. All the patients received perioperative antibiotics. One umbilical port had a hernia diagnosed 2 weeks postoperatively. Four of the 600 ports (0.6%) developed skin dehiscence secondary to superficial wound infection within 1 week postoperatively. At our institution, the overall incidence of port-site complications after PURS was 0.83%. This is slightly lower than the published incidence in adults undergoing conventional laparoscopy. Due to the low incidence of complications it is difficult to draw conclusions on contributing factors.
