Considerations regarding pain management and anesthesiological aspects in pediatric patients undergoing minimally invasive surgery: robotic vs laparoscopic-thoracoscopic approach

In the last decade, the applicability of robotic surgery has been demonstrated in many interventions, expanding the indications of minimally invasive surgery also to pediatrics. The aim of the study is to evaluate postoperative pain to demonstrate better control following robotic procedures compared to thoraco-laparoscopic surgery. An observational, retrospective, multicentre study was performed involving 204 children undergoing robot-assisted surgery and thoraco/laparoscopic surgery at the Istituto Giannina Gaslini in Genoa and the Siena University Hospital (2013-2017): 83 children underwent robotic-assisted surgery and 121 thoracic-laparoscopic surgery. Personal data and type of intervention were assessed, dividing the patients into four categories: thoracic, gastrointestinal, hepatobiliary and urological surgeries. We analyzed the anesthetic risk according to ASA classification by type of intervention, the type of anesthesia used, the anesthetic drugs used during surgery and in the postoperative period. Both the problems that occurred during the procedures and the number of interventions converted into open during robotic surgery and laparoscopic thoracic surgery were analyzed. Pain was measured on the 1st, 2nd and 3rd day (FLACC or NRS scales). By comparing the two groups (robotics-non-robotics), the analysis shows that postoperative pain does not change with the chosen approach, but always maintains very low values, typical of minimally invasive surgery. The pain score is significantly higher in patients undergoing thoracic surgery, either robotic or thoracoscopic, compared to those undergoing gastrointestinal surgery (P corrected according to Bonferroni: 0.0006) and those undergoing urological intervention (P corrected according to Bonferroni: 0.04). In conclusion, no significant change in the intensity of postoperative pain between the two groups was found, while it is seen that the pain in patients undergoing thoracic interventions (robotic/thoracoscopic) is more intense than that reported for other types of interventions.
