(1) Background: This study comprehensively compared robotic pancreatic surgery with vascular resection (RPS-VR) to other surgical procedures in the treatment of pancreatic ductal adenocarcinoma (PDAC). (2) Methods: A systematic review of relevant literature was conducted to assess a range of crucial surgical and oncological outcomes. (3) Results: Findings indicate that robotic surgery with vascular resections (VRs) significantly prolongs the duration of surgery compared to other surgical procedures, and they notably demonstrate an equal hospital stay. While some studies reported a lower conversion rate and a higher rate of blood loss and blood transfusion in the RPS-VR group, others found no significant disparity. Furthermore, RPS-VR consistently correlated with comparable recurrence rates, free margins R0, postoperative mortality, and complication rates. Concerning the last one, certain reviews reported a higher rate of major complications. Overall survival and disease-free survival remained comparable between the RPS-VR and other surgical techniques in treating PDAC. (4) Conclusions: The analysis emphasizes how RPS-VR is a resembling approach in terms of surgical outcomes and aligns with existing literature findings in this field.

In the field of surgery, the idea of performing organ transplants in a minimally invasive fashion has always been a significant technical challenge. The advent of the robotic approach facilitated the overcoming of difficulties in highly complex surgical procedures that demand high technical skill. Furthermore, robotic transplants are showing significant benefits in patient outcomes, particularly in the obese population. The purpose of this review is to provide an overview of the current state of robotics applications for transplant surgery. Kidney transplants were the first to be performed using a fully robotic approach. Since then, robotic surgery has gradually been applied to other organ transplants, with very recent reports of fully robotic lung and liver transplants. Further experiences and studies will be needed to verify their effectiveness and to satisfy some concerns regarding the longer warm ischemia time related to the robotic approach in comparison with open surgery.

Background: Robotic liver resections (RLRs) are increasingly performed worldwide. The IWATE criteria offer a standardized classification to correlate the complexity of these procedures with surgical outcomes. This study analyzes a single surgeon’s experience with RLR and evaluates the applicability and correlation of the IWATE criteria. Methods: We conducted a retrospective analysis of 188 RLRs performed by a single surgeon at the University of Illinois at Chicago from June 2007 to May 2023. Data on patient demographics, surgical details, pathology, and 30-day morbidity and mortality were collected. Surgical data included operation duration, blood loss, conversion rates, intraoperative and perioperative complications, and length of hospital stay (LOS). Patients were categorized into four groups according to the IWATE criteria. Results: Patients were evenly distributed across the four groups, except for age and preoperative chemotherapy rates, which were significantly different. Operative times (OTs) and estimated blood loss (EBL) increased with procedure complexity, ranging from 148 to 350 minutes and 75 to 400 mL (P<0.001). There were 18 conversions (9.6%), with a significantly higher rate in the Expert and Advanced groups (P<0.001). Intraoperative transfusions followed the same pattern. Postoperative outcomes showed a significant difference in median hospital stay (P<0.001), varying from 3 to 7 days (Low to Expert groups). There were 8 major complications and a 3.7% readmission rate, with no 30-day mortality, and no significant difference in complication distribution among groups. The overall R0 resection rate was 96.3%. Conclusions: The IWATE criteria effectively correlate with surgical outcomes in our series, providing a valuable tool for standardizing procedure complexity and facilitating outcome comparisons.

El diseño sísmico o la verificación de presas de escollera en la práctica convencional de ingeniería se lleva a cabo teniendo en cuenta las recomendaciones proporcionadas por las directrices del código, que suelen definir un terremoto máximo creíble en el sitio en términos de un espectro de respuesta de campo libre y registros sísmicos compatibles con el espectro. Sin embargo, se observa que los códigos de diseño no proporcionan directrices específicas sobre cómo definir otras características de la entrada sísmica; como la naturaleza de las ondas sísmicas entrantes, la variabilidad espacial de la acción sísmica, la topografía del sitio y los efectos de la presa en 3D. El presente estudio se centra en la evaluación de la influencia del ambiente sísmico en los asentamientos sísmicos de una presa de escollera, considerando escenarios constituidos por ondas de cuerpo (P y S) y ondas de superficie (Rayleigh). Los resultados muestran que un entorno sísmico formado por ondas de Rayleigh puede dar lugar a asentamientos significativamente mayores en la cresta de la presa que los producidos por un entorno sísmico formado únicamente por ondas de cuerpo.
