Megarrectosigmoides por constipación crónica idiopática, sigmoidectomía con robot en el paciente pediátrico. Primer caso en México.

We present the first pediatric case of Da Vinci Xi robot-assisted video sigmoidectomy in a 9-year-old male with chronic idiopathic constipation refractory to medical treatment and megarectosigmoid. He underwent sigmoidectomy with primary anastomosis without exceeding the peritoneal reflection. Sigmoidectomy in patients with intractable chronic constipation results in dramatic improvement, with reduction or elimination of laxative measures. Robot-assisted sigmoid resection is a safe minimally invasive alternative in the pediatric patient.

Se presenta el primer caso pediátrico de sigmoidectomía videoasistida por robot Da Vinci Xi en un varón de 9 años con constipación crónica idiopática refractaria al tratamiento médico y megarrectosigmoides. Se le realizó sigmoidectomía con anastomosis primaria sin rebasar la reflexión peritoneal. La sigmoidectomía en pacientes con constipación crónica intratable resulta en una notable mejoría, con reducción o eliminación de medidas laxantes. La resección del sigmoides con asistencia de robot es una alternativa de mínima invasión segura en el paciente pediátrico.

Characteristics of patients undergoing robotic-assisted prostatectomy. Observational study / Características de pacientes sometidos a prostatectomía robótica. Estudio observacional

Abstract Introduction Prostatectomy is the standard treatment for patients with clinically localized prostate cancer. Currently, robot-assisted radical prostatectomy (RARP) is widely used for its advantages, as it provides better visualization, precision, and reduced tissue manipulation. However, RARP requires a multidisciplinary approach in which anesthesia and analgesia management are especially important. Objective This study aims to describe our experience delivering anesthesia for the first cases of patients undergoing RARP in a teaching hospital in Bogotá, Colombia. Methodology An observational study was conducted. We included all patients undergoing RARP from September 2015 to December 2019 at Fundación Santa Fe de Bogotá. All patients with incomplete data were excluded. Patient demographics were recorded, and significant perioperative events were reviewed. Results A total of 301 patients were included. At our institution, the mean age for patients undergoing RARP was 61.4 ± 6.7 years. The mean operative time was 205 ± 43 min and mean blood loss was 300 [200400] mL. Only 6 (2%) patients required transfusion. Age and BMI were not associated with clinical outcomes. Conclusions An adequate perioperative approach in RARP is important to minimize complications, which in this study and in this institution were infrequent.

Resumen Introducción La prostatectomía es el tratamiento estándar para pacientes con cáncer de próstata localizado. Actualmente, la prostatectomía radical asistida por robot es ampliamente utilizada por sus ventajas en visualización, precisión y manipulación de los tejidos. Sin embargo, este abordaje requiere un manejo multidisciplinario, pues el enfoque analgésico y anestésico es fundamental para optimizar los desenlaces. Objetivo Describir los primeros casos de prostatectomía radical asistida por robot realizadas en un hospital universitario de cuarto nivel en Bogotá, Colombia. Metodología Estudio observacional en el cual se incluyeron todos los pacientes sometidos a prostatectomía radical asistida por robot (PRAR) en el hospital Fundación Santa Fe de Bogotá entre septiembre de 2015 y diciembre de 2019. Se excluyeron los pacientes con historia clínica incompleta. Se registraron los datos demográficos y se revisaron los eventos perioperatorios importantes. Resultados Se analizaron 301 pacientes. La edad media de pacientes sometidos a PRAR fue 61,4 ± 6,7 años. El tiempo quirúrgico promedio fue 205 ± 43 minutos y la pérdida sanguínea media fue 300 [200-400] mL. Solo 6 pacientes (2 %) requirieron transfusión. La edad y el IMC no mostraron una asociación relevante con los desenlaces clínicos. Conclusiones El adecuado abordaje perioperatorio en PRAR es importante para minimizar las complicaciones, las cuales en este estudio y en esta institución fueron infrecuentes.

Robotic repair of incarcerated morgagni hernia in an adult on the acute care surgery service

INTRODUCTION: Morgagni hernia is a relatively uncommon anterior diaphragmatic defect, particularly in adults. We describe the case of a patient who presented with an incarcerated Morgagni hernia and was repaired by an Acute Care Surgery service. DESCRIPTION: The patient is a 29 year old male who presented with a picture of bowel obstruction. CT scan revealed a Morgagni hernia with incarcerated stomach and colon. He was taken to the operating room for robotic repair. The hernia was reduced. The defect measured 10 x 7cm, a composite mesh was interposed, and sutured in place. The patient was discharged on postoperative day 5 and has done well at 1 year follow up. CONCLUSION: Robotic surgery offer the chance to apply minimally invasive techniques for urgent surgical care. This is the first reported case of an incarcerated Morgagni hernia repaired urgently using robotic techniques, and performed by acute care surgeons.

Percutaneous Cryoablation versus Robot-Assisted Partial Nephrectomy of Renal T1A Tumors: a Single-Center Retrospective Cost-Effectiveness Analysis.

PURPOSE: To evaluate the cost-effectiveness of percutaneous cryoablation (PCA) versus robot-assisted partial nephrectomy (RPN) in patients with small renal tumors (T1a stage), considering perioperative complications. MATERIALS AND METHODS: Retrospective study from November 2008 to April 2017 of 122 patients with a T1a renal mass who after being analyzed by a multidisciplinary board underwent to PCA (59 patients) or RPN (63 patients). Hospital costs in US dollars, and clinical and tumor data were compared. Non-complicated intervention was considered as an effective outcome. A hypothetical model of possible complications based on Clavien-Dindo classification (CDC) was built, grouping them into mild (CDC I and II) and severe (CDC III and IV). A decision tree model was structured from complications of published data. RESULTS: Patients who underwent PCA were older (62.5 vs. 52.8 years old, p < 0.001), presented with more coronary disease and previous renal cancer (25.4% vs. 10.1%, p = 0.023 and 38% vs. 7.2%, p < 0.001, respectively). Patients treated with PCA had a higher preoperative risk (American Society of Anesthesiologists-ASA ≥ 3) than those in the RPN group (25.4% vs. 0%, p < 0.001). Average operative time was significantly lower with PCA than RPN (99.92 ± 29.05 min vs. 129.28 ± 54.85 min, p < 0.001). Average hospitalization time for PCA was 2.2 ± 2.95 days, significantly lower than RPN (mean 3.03 ± 1.49 days, p = 0.04). The average total cost of PCA was significantly lower than RPN (US$12,435 ± 6,176 vs. US$19,399 ± 6,047, p < 0.001). The incremental effectiveness was 5% higher comparing PCA with RPN, resulting a cost-saving result in favor of PCA. CONCLUSION: PCA was the dominant strategy (less costly and more effective) compared to RPN, considering occurrence of perioperative complications.

Reemplazo parcial de rodilla mediante el sistema robótico NAVIO: resultados clínicos postquirúrgicos evaluados mediante Knee injury Osteoartritis Outcome Score / Robotic-assisted unicompartmental knee replacement with NAVIO surgical system: outcome evaluation using the Knee Injury Osteoarthritis Outcome Score

INTRODUCCIÓN: La osteoartritis de rodilla es una de las patologías musculo esqueléticas más prevalentes en el mundo, y el tratamiento quirúrgico es hasta hoy, la única terapia definitiva. El sistema NAVIO™ es uno de los dispositivos robóticos más recientemente a disposición para realizar el reemplazo parcial de rodilla. Ofrece gran precisión en el proceso de alineamiento, remodelado óseo y balance de los tejidos blandos, sin exponer al paciente a la radiación ni a los costos de la tomografía computarizada que suele realizarse con los sistemas robóticos actuales antes del procedimiento artroplástico. OBJETIVO: Evaluar los resultados medidos por los pacientes antes y después del procedimiento artroplástico mediante NAVIO™ y la prótesis STRIDE™. MATERIAL Y MÉTODO: Aplicación del cuestionario Knee injury Osteoarthritis Outcome Score (KOOS) en el preoperatorio y a los 12 meses del procedimiento quirúrgico de los primeros 47 pacientes operados usando NAVIO™ en Cornerstone Regional Hospital, Edinburg, Texas. RESULTADOS: Se observó una mejoría de las muestras normalizadas en todas las categorías con un p < 0.05. COMENTARIO: Estudios recientes han sugerido que en Chile la presentación de la osteoartritis se asocia a un grado de severidad menor que en el resto de los países latinoamericanos. Lo cual torna relevante la aplicación de terapias quirúrgicas más conservadoras, que ofrezcan al paciente un alivio sintomático y le permitan reestablecerse a sus actividades cotidianas causando el mínimo impacto posible. Esas ventajas fueron observadas en los pacientes sometidos a ese procedimiento quirúrgico. CONCLUSIONES: La artroplastia unicompartimental de rodilla mediante el sistema quirúrgico NAVIO™ y prótesis STRIDE™ demostró mejorar substancialmente la vida diaria y calidad de vida de los pacientes, disminuyendo el dolor y mejorando su función durante las actividades deportivas y recreacionales.

INTRODUCTION: Knee osteoarthritis is one of the most prevalent musculoskeletal pathologies in the world and the surgical treatment is until today the only definitive therapy. NAVIO™ system is one of the most recently available robotic devices for partial knee arthroplasty. It offers great precision in the process of alignment, bone remodeling and soft tissue balancing without exposing the patient to the radiation or the costs of the CT scan usually performed before the arthroplasty with the current robotic systems. OBJECTIVE: To evaluate the outcomes measured by the patients before and after the arthroplasty using NAVIO™ and the STRIDE™ prosthesis. MATERIALS AND METHODS: Application of the Knee Injury Osteoarthritis Outcome Score (KOOS) questionnaire in the preoperative and 12 months after the surgical procedure of the first 47 patients operated using NAVIO™ at Cornerstone Regional Hospital, Edinburg, Texas. RESULTS: There was an improvement of the normalized samples in all the categories with p < 0.05. COMMENTARY: Recent studies have suggested that in Chile the presentation of osteoarthritis is associated with a lower degree of severity compared with the rest of Latin American countries. This makes relevant the application of more conservative surgical therapies, which could offer the patient symptomatic relief and allow them to reestablish their daily activities causing the minimum impact possible. These advantages were observed in patients undergoing this surgical procedure. CONCLUSIONS: Unicompartmental knee replacement using NAVIO ™ surgical system and STRIDE™ prosthesis demonstrated a substantial improvement in patient's quality of life, reducing pain and improving their function during sports and recreational activities.
