Results of a Novel Long-Term Method for Laparoscopic Skills Online Training.

Introduction: Ensuring patient safety in minimally invasive surgery (MIS) within the field of pediatric surgery requires systematic and extensive practice. Many groups have proposed mastery learning programs encompassing a range of training methods. However, short courses often have a narrow focus on specific objectives, limiting opportunities for sustained training. Our aim was to analyze our results with an online long-term competency-based and supervised training. Methods: This is a retrospective cohort study with prospective data collection of scores and performance of trainees during online courses from October 2020 to April 2023. Results: All participants (n = 76) were able to set up their personal training gym and complete the intensive stage of the course. The total score evolved from 2.60 ± 0.56 at the first meeting to 3.67 ± 0.61 at the fourth meeting, exhibiting a significant difference (P < .013). A considerable drop out was observed in the follow-up stage, with only 53.8% of the participants completing the course. When compared with the first meeting, they also showed a significant improvement with a mean general score of 3.85 ± 0.25 (P < .013) Conclusion: We have presented a novel online training program, based on continuous training that demonstrated that the unlimited access to a personal training gym allows surgeons to improve and maintain MIS skills.

Lessons Learned after 176 Patients Treated with a Standardized Procedure of Thoracoscopic Cryoanalgesia during Minimally Invasive Repair of Pectus Excavatum.

BACKGROUND: Intrathoracic intercostal cryoanalgesia (Cryo) during minimally invasive repair of pectus excavatum (MIRPE) reports have been related to improved pain management, although its extent differs amongst studies. We aimed to report our experience using a standardized perioperative approach including Cryo during MIRPE, and compare our actual results with those of a previous thoracic epidural analgesia (TE) cohort. Lessons learned are summarized. METHODS: Retrospective study including patients undergoing Cryo during MIRPE between October 2018 and May 2023. Results with a standardized perioperative approach were analyzed. We then compared our Cryo cohort with a previous cohort of 62 patients who underwent TE and MIRPE between 2013 and 2018. Continuous variables were reported as mean and standard deviation, and as median (interquartile range) for variables with non-uniform distribution. RESULTS: We performed 176 Cryo during MIRPE (16.8 ± 4.6 years), with a mean postoperative length of stay (LOS) of 1.4 ± 0.8 days and a median total requirement of 7.5 (0.0; 15.0) oral morphine equivalents (OME) (mg). Patients with Cryo had a significantly lower mean LOS (1.4 ± 0.8 vs. 3.6 ± 1.0 days, p < 0.0001), and median total opioid requirement [7.5 (0.0; 15.0) vs. 77.4 (27.0; 115.5 OME (mg), p < 0.0001) compared to TE patients. Lessons learned included ensuring adequate contact of the cryoprobe with the target, proper exposition, and specialized multidisciplinary perioperative patient and family support, including psychology and physical therapy. CONCLUSIONS: In this study, we reported lessons learned after performing a standardized protocol of perioperative care in patients undergoing Cryo during MIRPE. This protocol enabled the achievement of a short LOS and low postoperative opioid requirement. TYPE OF STUDY: Retrospective comparative study. LEVEL OF EVIDENCE: III.

Remote treatment of pectus carinatum (Telepectus) during the COVID-19 pandemic.

BACKGROUND/PURPOSE: To report telemedicine's feasibility and satisfaction rates for treating patients with pectus carinatum using a dynamic compressor system. We analyzed treatment adherence in comparison with the previous, non-pandemic year. MATERIALS AND METHODS: Retrospective analysis including patients with pectus carinatum under treatment with a dynamic compressor system using telemedicine at the chest wall centers from two hospitals, private and public, between April and July 2020. A free video conference platform for teleconsultations was employed. We evaluated the incidence of pectus cases with telemedicine, the number of dynamic compressor system prescriptions, the number of patients in the correction phase, and the number who ended treatment. To assess adherence, we compared our cohort with an in-person cohort during the same time frame of the previous, non-pandemic year. In addition, we performed a patient satisfaction survey comprising questions related to socioeconomic status, the likeability of telemedicine, simplicity of modification of the system, and desire to continue with telepectus after the pandemic. RESULTS: One hundred and thirty-six telepectus consultations were performed in 76 patients. During this time frame, 15 patients started using the dynamic compressor system. Compared to the previous, non-pandemic year, the number of consultations per patient was similar (2019: 1.92 ± 1 .0 vs. 2020: 1.79 ± 0.8, p = 0.32), and there was a significant reduction in the number of dropouts with the use of telemedicine (9% vs. 1%, p = 0.025). Fifty-nine patients answered the satisfaction survey. All of them solved their doubts through telemedicine. Overall, 95% found telemedicine comfortable. Of note, those with a lower income evidenced the highest intention in continuing with telemedicine. CONCLUSIONS: We demonstrated the feasibility of remote care of patients with pectus carinatum using a dynamic compressor system with a similar frequency of consultations compared to in-person medical care. Telepectus patients revealed a high rate of satisfaction irrespective of their socioeconomic status. LEVEL OF EVIDENCE: IV. TYPE OF STUDY: Retrospective study.

Estudio del oído con TC Multidetector de 64 canales / 64 - Detector CT findings in the study of the ear

El oído es una estructura anatómica compleja. Su estudio y comprensión resultan un reto diario para el radiólogo, siendo la tomografía computada una herramienta esencial para su estudio. La tomografía computada convencional con cortes finos en planos axiales y coronales permite una buena visualización de las diferentes estructuras. Sin embargo, se necesitan tiempos prolongados para su realización y posicionamientos incómodos o intolerables para muchos pacientes. Además la visualización de algunas de sus estructuras es limitada. La tomografía axial computada multidetector de 64 canales a nuestro medio permite optimizar el estudio de la compleja y pequeña anatomía del oído. La realización de adquisiciones volumétricas con cortes de 0,5 mm, con reconstrucciones multiplanares en los tres planos básicos, en planos curvos y reconstrucciones tridimensionales, hacen posible la visualización detallada de las estructuras en escasos segundos y en condiciones cómodas para el paciente. Nuestro propósito en este artículo es demostrar la utilidad de las reconstrucciones, particularmente en planos oblicuos, para identificar y analizar los diferentes reparos anatómicos del oído y alcanzar la visualización óptima de la anatomía relevante del hueso temporal.

The ear is a complex anatomic structure. Its study and understanding represent a constant challenge for the radiologist. As a consequence the computed tomography becomes an essential tool for its examination. Conventional tomographic examination with both axial and coronal reconstruction of the image allows a satisfactory visualization of the different structures. However, the study requires long periods of time for its acquisition and uncomfortable or intolerable positions for the patients. Moreover, the characterization of some structures of the ear becomes limited. Sixty-four slice multidetector computed tomography allows the optimal study of the small and complex ear anatomy. Volumetric acquisitions with 0.5 mm slices, with multiplanar reconstructions in the three basic plans, in tri-dimensional reconstructions and curved plans, allow detailed visualization of structures in a few seconds, thuf avoiding patient discomfort. Our purpose in this article is to demonstrate the utility of reconstructions particularly in oblique planes, and reaching an optimal visualization of the temporal bone.
