Robotic-Assisted Laparoscopic Nissen Fundoplication with Gastrostomy Preservation in Neurologically Impaired Children

The Role of the Versius Surgical Robotic System in the Paediatric Population

The uptake of robot-assisted surgery has continuously grown since its advent in the 1990s. While robot-assisted surgery is well-established in adult surgery, the rate of uptake in paediatric surgical centres has been slower. The advantages of a robot-assisted system, such as improved visibility, dexterity, and ergonomics, could make it a superior choice over the traditional laparoscopic approach. However, its implementation in the paediatric surgery arena has been limited primarily due to the unavailability of appropriately sized instruments as per paediatric body habitus, therefore, requiring more technologically advanced systems. The Versius surgical robotic system is a new modular platform that offers several benefits such as articulated instruments which pass through conventional 5 mm ports, compact arms for easier manoeuvrability and patient access, the ability to mimic conventional port placements, and adaptive machine learning concepts. Prior to its introduction to paediatric surgery, it needs to go through a careful pre-clinical and clinical research program.

Meta analysis of robot-assisted versus conventional laparoscopic fundoplication in children

BACKGROUND

Minimally invasive fundoplication may be performed using either a robot-assisted (RF) or conventional laparoscopic (LF) technique. Evidence comparing RF and LF in children remains unclear. This study aims to elucidate the comparative safety and efficacy of RF versus LF by systematic review and meta-analysis.

METHODS

Comparative studies investigating RF versus LF in children were identified from multiple electronic literature databases. Meta-analysis was performed using random effects modeling. Safety parameters investigated were post-operative morbidity and intra-operative conversions. Efficacy outcomes of interest were operative success, re-operation, post-operative complications, length of hospital stay (LOS), total operating time (OT), analgesia requirement, and cost.

RESULTS

Six observational studies met inclusion criteria, reporting outcomes of 297 children. No randomized controlled trials were identified. Pooled analysis determined no statistically significant differences between RF and LF for conversions, OT, LOS, and post-operative complications. There was no standardized follow up beyond the early post-operative period to enable data synthesis for remaining outcomes of interest. Limited evidence indicates higher costs with RF.

CONCLUSIONS

Safety and short-term efficacy seem comparable between RF and LF in children. There is insufficient evidence to assess comparative effectiveness for many important procedure specific outcome measures. Higher quality and longer follow-up studies are required.

A literature review of the outcomes after robot-assisted laparoscopic and conventional laparoscopic Nissen fundoplication for gastro-esophageal reflux disease in children

BACKGROUND

Robot-assisted surgery is a promising technical innovation. Given the similarities between laparoscopic and robot-assisted surgery it is unlikely that randomized controlled trials would be conducted to disclose any differences between these two technical instruments. Thus, skepticism remains due to lack of any definitive conclusions in the literature.

AIMS

The aim of the study was to disclose any difference in outcome after robot-assisted (RNF) versus conventional laparoscopic (LNF) Nissen fundoplication for gastro-esophageal reflux disease in children.

MATERIALS AND METHODS

A literature review was carried out. Only studies comparing the two modalities were included. Operative time, duration of hospital stay, 30 days morbidity, mortality, conversion, recurrence and complication rates were analyzed. Review Manager 5.1.6 software, from the Cochrane library, was used for statistical analysis.

RESULTS

Three case series fulfilled the criteria for inclusion in this review. Data on 174 children were identified; 89 were operated on using the computer-assisted technology and 85 controls were operated on using the conventional laparoscopic technique. Data showed no significant difference between these two modalities.

DISCUSSION

This literature review demonstrates no significant difference between patients operated on with robot-assisted surgery and those undergoing conventional laparoscopic surgery regarding the parameters studied.

CONCLUSION

The robot-assisted Nissen fundoplication in children is a safe alternative to conventional laparoscopic surgery. No data support the need for case selection to one of these two minimally invasive procedures.

[Video-assisted surgery in children: current progress and future perspectives]

This review presents the evidence of video-assisted surgery in the pediatric population and discusses future progress in this field. Videosurgery minimizes the cosmetic impact and the pain induced by open procedures and has been in constant development in adults and children. Earlier training of surgeons and residents combined with advances in anesthetics and technology have expanded the use of videosurgery for more complex interventions. Although most feasible surgical procedures have been performed by laparoscopy, the literature has not yet defined it as the gold standard for most interventions, especially because of the lack of evidence for many of them. However, laparoscopy for cholecystectomy is now the preferred approach with excellent postoperative outcomes and few complications. Although no evidence has been demonstrated in children, laparoscopy has been shown to be superior in adults for gastroesophageal reflux disease and splenectomy. Laparoscopic appendectomy remains controversial. Nevertheless, meta-analyses have concluded in moderate but significant advantages in terms of pain, cosmetic considerations, and recovery for the laparoscopic approach. Laparoscopy is now adopted for undescended testes and allows both localization and surgical treatment if necessary. For benign conditions, videosurgery can be an excellent tool for nephrectomy and adrenalectomy. However, laparoscopy remains controversial in pediatric surgical oncology.

How to successfully implement a robotic pediatric surgery program: lessons learned after 96 procedures

BACKGROUND

Both our teams were the first to implement pediatric robotic surgery in France. The aim of this study was to define the key points we brought to light so other pediatric teams that want to set up a robotic surgery program will benefit.

METHODS

We reviewed the medical records of all children who underwent robotic surgery between Nov 2007 and June 2011 in both departments, including patient data, installation and changes, operative time, hospital stay, intraoperative complications, and postoperative outcome. The department's internal organization, the organization within the hospital complex, and cost were evaluated.

RESULTS

A total of 96 procedures were evaluated. There were 38 girls and 56 boys with average age at surgery of 7.6 years (range, 0.7-18 years) and average weight of 26 kg (range, 6-77 kg). Thirty-six patients had general surgery, 57 patients urologic surgery, and 1 thoracic surgery. Overall average operative time was 189 min (range, 70-550 min), and average hospital stay was 6.4 days (range, 2-24 days). The procedures of 3 patients were converted. Median follow-up was 18 months (range, 0.5-43 months). Robotic surgical procedure had an extra cost of <euro>1934 compared to conventional open surgery.

CONCLUSIONS

Our experience was similar to the findings described in the literature for feasibility, security, and patient outcomes; we had an overall operative success rate of 97 %. Three main actors are concerned in the implementation of a robotic pediatric surgery program: surgeons and anesthetists, nurses, and the administration. The surgeon is at the starting point with motivation for minimally invasive surgery without laparoscopic constraints. We found that it was possible to implement a long-lasting robotic surgery program with comparable quality of care.
