RESUMEN
Background: The introduction of splenectomy in pediatric robotic surgery programs remains controversial. The aim of this study is to evaluate the feasibility and safety of robotic assisted splenectomy (RAS) in children and compare its outcomes with the laparoscopic splenectomy (LAS). Method: A single institution retrospective study was performed (2011-2020). We used the minimally invasive splenectomy score described by Giza et al. to measure the level of technical difficulty. The data collected for each procedure included its duration, the need for blood transfusion, complications, analgesic use, and the length of hospital stay. A standard univariate analysis is applied. Results: We recorded 41 cases (26 LAS and 15 RAS). The mean age was 11 years [7.00; 13.5]. The operating time was 97 minutes [85.5-108] for LAS and 223 minutes [190-280] for RAS (P < .001). The length of stay was 6.50 days [5.00-8.00] for LAS and 5 days [5.00-5.50] for RAS (P = .055). The cumulative use of level III analgesic was not statically different (P = .29). Two cases of difficult splenectomy were found in each group with comparable performances. In the RAS, we demonstrated the improved outcomes with the progression of the learning curve of a single surgeon. Conclusions: In our experience (as in the literature), RAS remains safe, but offers no additional advantage compared to laparoscopy as the cost and the operating time are higher. Our study has the advantages of having a 9 years long evolving experience, including broad indications in comparison to other pediatric studies.

BACKGROUND: Recent studies suggest that isolated sonographic assessment of the respiratory, cardiac, or neuromuscular functions in mechanically ventilated patients may assist in identifying patients at risk of postextubation distress. The aim of the present study was to prospectively investigate the value of an integrated thoracic ultrasound evaluation, encompassing bedside respiratory, cardiac, and diaphragm sonographic data in predicting postextubation distress. METHODS: Longitudinal ultrasound data from 136 patients who were extubated after passing a trial of pressure support ventilation were measured immediately after the start and at the end of this trial. In case of postextubation distress (31 of 136 patients), an additional combined ultrasound assessment was performed while the patient was still in acute respiratory failure. We applied machine-learning methods to improve the accuracy of the related predictive assessments. RESULTS: Overall, integrated thoracic ultrasound models accurately predict postextubation distress when applied to thoracic ultrasound data immediately recorded before the start and at the end of the trial of pressure support ventilation (learning sample area under the curve: start, 0.921; end, 0.951; test sample area under the curve: start, 0.972; end, 0.920). Among integrated thoracic ultrasound data, the recognition of lung interstitial edema and the increased telediastolic left ventricular pressure were the most relevant predictive factors. In addition, the use of thoracic ultrasound appeared to be highly accurate in identifying the causes of postextubation distress. CONCLUSIONS: The decision to attempt extubation could be significantly assisted by an integrative, dynamic, and fully bedside ultrasonographic assessment of cardiac, lung, and diaphragm functions.
