Robot-Assisted Laparoscopic Urachal Excision Using Hidden Incision Endoscopic Surgery Technique in Pediatric Patients.

Introduction: Although laparoscopic urachal excision in children has been well reported, there are limited data on a robot-assisted surgery (RAS) approach. The hidden incision endoscopic surgery (HIdES) technique is an established method of eliminating visible scars following a number of RAS urologic procedures. We report our experience of using a robotic approach to treat urachal anomalies in children, and we present the first description of utilizing the HIdES port configuration for this procedure. Materials and Methods: We retrospectively reviewed pediatric patients who underwent resection of a urachal remnant at our institution from 2013 to 2018. Surgical techniques were either the traditional open approach (OA) or RAS. HIdES trocar placement configuration was employed in all robotic cases. Patient demographics, perioperative data, pathology reports, and outcomes were abstracted and compared. Results: Twenty-three patients underwent a urachal remnant resection in the study period (RAS: 14 patients vs OA: 9 patients). RAS patients were older (8.5 vs 2.0 years, p = 0.031) and weighed more than OA patients (36.1 vs 13.9 kg, p = 0.063). Median operative time for RAS was longer than OA operative time (136 vs 33 minutes, p < 0.01). Fewer RAS patients were outpatient compared with OA (7.1% vs 66.7%, p < 0.01), but with a median length of stay of 1 day (0-1 day). Two patients (14.3%) in the RAS group experienced postoperative complications within 1 week of the procedure compared with 1 (11.1%) in the OA group. There was no significant difference in blood loss, postoperative narcotic requirements, or duration of follow-up between both groups. Conclusion: RAS is a safe and feasible alternative to open surgery for urachal anomalies. Complete excision can be achieved by using HIdES port configuration, allowing for excellent cosmetic outcomes that are superior to traditional surgical scars without limitation to essential surgical ergonomics.

Discrepancies in Self-Reported and Actual Conflicts of Interest for Robotic Pediatric Urological Surgery.

PURPOSE: Transparency of conflicts of interest is essential when assessing publications that address the benefits of robotic surgery over traditional laparoscopic and open operations. We assessed discrepancies between self-reported and actual conflicts of interest as well as whether conflicts of interest are associated with favorable endorsement of robotic surgery. MATERIALS AND METHODS: We searched the Embase® and MEDLINE® databases for articles on robotic surgery within pediatric urology. We included English language articles published since 2013, when data in the Open Payments program (Centers for Medicare and Medicaid Services, Baltimore, Maryland) became available. For all United States based authors Open Payments was used to identify the total amount of financial payment received from Intuitive Surgical®. Chi-square test was used to assess the association between conflicts of interest and favorable endorsement of robotic surgery. RESULTS: A total of 191 articles were initially identified. After exclusion criteria were applied 107 articles remained (267 distinct authors). Of the articles 86 (80.4%) had at least 1 author with a history of payment from Intuitive Surgical, with 79 (91.9%) having at least 1 author who did not declare a conflict of interest despite history of payment. A total of 44 authors (16.5%) had a history of payment from Intuitive Surgical, with an average payment of $3,594.15. Articles with a first and/or last author with a history of payment were more likely to contain a favorable endorsement of robotic surgery compared to articles without a history of payment (85.1% vs 63.6%, p = 0.0124). CONCLUSIONS: Nondisclosure of conflict of interest with Intuitive Surgical is extremely common within pediatric urology. Steps to ensure accurate reporting of conflicts of interest are essential. There appears to be an association between a history of payment and favorable endorsement of robotic surgery.
