Filter by:Even after the wide introduction of chemo/radiotherapy in the treatment algorithm, adequate surgery remains the cornerstone of gastric cancer treatment with curative intent. A proper D2 lymphadenectomy is associated with improved cancer specific survival as confirmed in Western countries by fifteen-year follow-up results of Dutch and Italian randomized trials. In clinical practice, the total number of harvested lymph nodes is often considered as a surrogate marker for adequate D2 lymphadenectomy; nonetheless, the number of retrieved nodes does not necessarily correlate with residual nodes, which intuitively could represent a more reliable marker of surgical adequacy. The availability of an efficient tool for evaluating the absence of residual nodes in the operative field at the end of node dissection could better correlate with survival outcomes. The goal of this multicentric observational prospective study is to test the reliability of a new score (PhotoNodes Score) created to rate the quality of the lymphadenectomy performed during minimally invasive gastrectomy for gastric cancer. The score is assigned by assessing the absence of residual nodes at the end of node dissection on a set of laparoscopic/robotic high quality intraoperative images collected from each patient undergoing a minimally invasive gastrectomy with D2 node dissection. Ideally, this tool could be a new indicator of the quality of D2 dissection and could assume a prognostic role in the treatment of gastric cancer.
This study aims to explore through a multi-center, randomized controlled clinical study whether robot-assisted radical resection of right colon cancer is superior to laparoscopic surgery in terms of surgical quality and oncological prognosis.
A retrospective cohort study, conducted nationwide（China） and across multiple centers, aimed to compare the surgical quality and short-term outcomes of R-NOSES （robotic natural orifice specimen extraction surgery）with R-TSES （robotic transabdominal specimen extraction surgery） for early-stage rectal cancer.
Our team has previously published articles providing detailed descriptions of the steps involved in both RS and LS. All surgeries adhered to the total mesorectal excision (TME) principle. In RS, a surgeon employed the Da Vinci Xi surgical system featuring a five-port setup, while five physicians conducted LS with a similarly configured five-port approach. Both the RS and LS doctors are experienced. The surgeries were conducted according to standard procedures, and the RS group utilized totally robotic rectal resection.
The field of robotic-assisted laparoscopic surgery increases all the time. Older and more fragile patients which are not suitable for major open surgery could be scheduled for robotic- assisted surgery. The peroperative anesthesiological challenges and stresses during this type of surgery could anyway be even more prominent. The extreme positioning of patients during robotic surgery in the pelvis, often 30 degrees head down tilting (Trendelenburg positioning), should increase the work load of the heart significantly. There are no studies concerning fragile patients with heart failure during these conditions. In this study the circulatory effects in patients with normal heart function and preexisting heart failure will be studied during robotic surgery in extreme Trendelenburg positioning During surgery the work load and performance of the heart will be monitored using an esophageal doppler and optical spectrophotometry measuring regional saturation of the brain. This study can identify patients at risk of developing critical circulatory failure during this type of surgery.
The goal of this observational study is to compare outcomes of robot-assisted kidney transplantation and open kidney transplantation. The main questions are - comprehensively analyze our early experience of robot-assisted kidney transplant patients and compare the results with those of open kidney transplant patients
Open Kasai portoenterostomy (OKPE) is considered the standard treatment procedure for biliary atresia (BA). Robotic-assisted Kasai portoenterostomy (RAKPE) has been utilized to treat BA. However, there were no randomized controlled trials to verify its effectiveness. The objection was to compare the efficacy of Da Vinci robot-assisted with open Kasai portoenterostomy for biliary atresia.
The goal of this preclinical trial is to learn about the benefits and limitations of novel robotic devices for microsurgery, based on different levels of microsurgical experience. The main questions it aims to answer are: Is robot-assisted microsurgery faster, better and more ergonomic than conventional microsurgery in a preclinical standardized setting? Participants will perform microvascular anastomoses on 1.0-mm-diameter artificial silicone vessels using a conventional manual approach versus a novel robot-assisted approach. Researchers will compare the performance of novices, advanced participants and experts to evaluate the role of microsurgical experience when learning the new technique.
Carbon dioxide (CO2) pneumoperitoneum and clasp-knife positioning are commonly used to improve surgical access during robot-assisted laparoscopic urological surgery. However, these methods are sometimes associated with several unwanted cardiopulmonary effects such as increased mean arterial pressure, decreased pulmonary compliance and functional residual capacity, increased peak inspiratory pressure, and respiratory acidosis in association with hypercarbia. Volume-controlled ventilation (VCV) is the most commonly used method of ventilation during general anesthesia. It provides fixed minute ventilation and pulmonary resistance, which affect airway pressure. In pressure-controlled ventilation (PCV), constant inspiratory airway pressure can be achieved by decelerating the flow. However, minute ventilation is not fixed . CO2 pneumoperitoneum in the clasp-knife positioning can influence hemodynamic variables, including blood pressure, heart rate, and cardiac output. This is because changes in airway pressure affect intrathoracic pressure and the function of the heart itself. In this randomized study, we investigated the effects of VCV and PCV on peak inspiratory pressure during robot-assisted laparoscopic urological surgery involving CO2 pneumoperitoneum in the clasp-knife position.
