Robotic Surgical Procedures

To evaluate the safety and efficacy of SP1000 and conventional laparoscopy in radical gastrectomy for proximal gastric cancer.

This is a single-center retrospective observational cohort study evaluating surgical and clinical outcomes in pediatric patients undergoing robotic surgery at a tertiary children's hospital. All consecutive patients younger than 18 years who underwent robotic-assisted procedures (digestive, urologic, gynecologic, or thoracic surgery) between January 2025 and December 2025 at Meyer Children's Hospital IRCCS will be included. The primary objective is to describe postoperative complications within 30 days. Secondary objectives include conversion to open surgery, reintervention and readmission rates, length of hospital stay, postoperative pain, recovery parameters, and recurrence of the underlying disease within 12 months. Data will be collected retrospectively from electronic medical records, operative registries, laboratory reports, and follow-up documentation up to 12 months after surgery.

The purpose of this clinical trial is to observe the improvements in clinical symptoms and imaging outcomes for brainstem hemorrhage using robot-assisted stereotactic puncture, evaluate the clinical efficacy and safety of this treatment, and explore the development of a high-precision, intelligent, and individualized microsurgical diagnosis and treatment process for brainstem hemorrhage. The main questions it aims to address are: * Establish a multi-center clinical database for brainstem hemorrhage. * Clinically observe and evaluate the intervention effects of robot-assisted stereotactic puncture on brainstem hemorrhage, compare it with the traditional conservative treatment control group, and investigate its efficacy and impact on patient survival, motor evoked potentials, and the degree of neurological deficits. * Optimize the Artificial Intelligence (AI) algorithm-based robotic surgical assistance system, and explore the prediction of preoperative brainstem hematoma stability and hematoma path planning. Participants in the experimental group will: * Undergo robot-assisted stereotactic minimally invasive surgery for brainstem hematoma puncture * Receive conservative non-surgical treatment. If there is a control group: the researchers will compare the conservative non-surgical treatment group to evaluate the effectiveness of robot-assisted stereotactic minimally invasive surgery for brainstem hematoma puncture.

This study aims to evaluate the impact of different extubation strategy on the occupancy time of operating room (OR) and the incidence of adverse events and quality of recovery after robotic-assisted surgery. The investigators hypothesize that extubation in the post-anesthesia care unit (PACU) may reduce OR occupancy time without increasing adverse events or worsening quality of recovery early after robotic-assisted surgery. This strategy may enhance perioperative efficiency while maintaining clinical safety.

Patients undergoing robotic assisted hysterectomy in three different hospitals in Stockholm will be randomized to day-care (going home the same day as the surgery) or admission (staying at least one night after surgery). The aim with this study is to investigate if patients in day-care recover as fast/faster as the other group that stays in the hospital. Both patients with benign disease and malign disease (endometrial cancer) will be included in the study. Patients quality of life (QoL) will be measured before surgery and after surgery at day 3,7 and 30 with a questionnaire called Eq-5D-5L from Euroqol. The questionnaire is validated for postoperative QoL and widely used. Complications due to surgery within the 30 first days after surgery will also be recorded in the two groups to make sure it is safe for the patients to go home the same day as their surgery.

Single-port versus multi-port robotic surgery for rectal cancer

This is a retrospective, multicenter cohort study to compare short- and long-term outcomes between robotic and laparoscopic hemicolectomy of right colon cancer.

Pancreatic robotic surgery (PRS) has moved from an almost testimonial procedure to a moment of expansion that is not yet clearly defined. In the pioneering centres, the results achieved are superior to those of open surgery. At present, it is not known how many centres perform CRP, what type of operations they perform, what percentage of the total number of pancreatic operations CRP represents and what results are obtained. The aim of our project is to establish a national multicentre registry of robotic pancreatic surgery that will allow us to answer all these questions. Methodology: This is a one-year prospective multicentre registry involving all general and digestive surgery units in Spain that have a DaVinci robotic platform and wish to participate and perform robotic pancreatectomies. All adult patients undergoing robotic pancreatectomy at participating Spanish centres who meet the inclusion criteria will be included. The registry will be open until 31 March 2026 to include post-operative morbidity and mortality at 90 days. The number of pancreatic surgeries performed in that centre during the same period will be counted to determine the percentage of robotic pancreatic surgery per centre. Intraoperative complications will be measured according to the Satava classification modified by Halls et al. Postoperative complications will be classified according to the Clavien-Dindo classification and the CCI (Comprehensive Complication Index). Pancreatic fistula, postoperative bleeding and delayed gastric emptying were classified according to the ISGPS classification and biliary fistula according to the ISGLS classification.

This is a multicenter, superior, randomized controlled trial designed to compare Robotic-assisted total mesorectal excision (RATME) and laparoscopic-assisted total mesorectal excision (LATME) for middle and low rectal cancer. The primary endpoint is the incidence of intersphincteric resection (ISR). The secondary outcomes are coloanal anastomosis (CAA), conversion to open, conversion to transanal TME (TaTME), incidence of abdominoperineal resection (APR), postoperative morbidity and mortality within 30 days after surgery, pathological outcomes, long-term survival outcomes, functional outcomes, and quality of life.

The goal of this clinical trial is to learn the evidence-based medical value of 3D visualization techniques to improve tumor control, preservation of renal function, and perioperative safety in robot-assisted nephron sparing surgery for complex renal tumors. The main question it aims to answer is: Is 3D visualization techniques more effective in improving robot-assisted nephron sparing surgery for complex renal tumors in terms of tumor control, renal function preservation, and perioperative safety. The researchers will randomize participants into a 3D trial group and a conventional group for comparison. Participants will: Complete Blood routine, liver and kidney function tests on the first and third day after operation. Have Renography at 3 and 12 months after the operation. Cooperate with follow-up visits.

As China transitions into an aging society, the proportion of the elderly population is escalating, with a corresponding rise in the number of patients with knee joint diseases. Total knee arthroplasty stands as an effective treatment for joint disorders, effectively reducing knee pain, restoring functionality, and enhancing quality of life. The objectives of total knee arthroplasty are to relieve pain, restore function, and ensure a long-lasting implant. In recent years, technological advancements have integrated robotic assistance into total knee arthroplasty (TKA), aiding surgeons in planning and executing more accurate surgical plans, significantly enhancing precision and post-operative outcomes. However, the Mako mechanical axis alignment demonstrated during the Mako robot-assisted TKA procedure does not correspond to the actual straightening of the lower limb, and discrepancies may exist in sagittal alignment between Mako-assisted and manual TKA procedures, necessitating adjustments by surgeons based on their experience. Consequently, there is an urgent need to develop a mathematical formula that quantifies these differences to guide intraoperative alignment. Additionally, the Mako-assisted TKA femoral prosthesis exhibits a head-lowering issue, and differences exist in the posterior slope angle of the tibial plateau compared to manual TKA, necessitating further comparative analysis to draw definitive conclusions. This study will be carried out at the People's Liberation Army General Hospital, with an anticipated enrollment of approximately 100 participants.

ReSECT is a project promoted by the Spanish Society of Thoracic Surgery with the aim not only to become an indefinite, dynamic and inclusive registry, but also to establish a common structural framework for the development of future multicentre projects in the field of thoracic surgery in Spain. The goal of this nationwide prospective observational registry is: * To develop and validate forecasting tools based on powerful computational methods with the goal of assisting in decision-making and improving quality of care. * To evaluate the progressive implementation of certain surgical techniques that are on the rise, new technologies and future health programs. * To be aware of our results as specialty and professionals and to serve as a permanent benchmarking instrument in thoracic surgery. The first part of ReSECT, based on a personal registry design, will contemplate any thoracic surgical procedure performed by thoracic surgeons and residents in thoracic surgery in our country. Additionally, the Spanish thoracic surgery departments that voluntarily accept to collectively participate will contribute to specific surgical processes focused on certain procedures with specific objectives to be progressively implemented. The first and only surgical process implemented since the start of the ReSECT project will focus on patients to undergo anatomical lung resection with special interest in those cases whose reason for intervention was lung cancer. The main questions to answer in case of that first surgical process include: * What is the performance of current predictive models for perioperative and oncological outcomes in our country? * How could we modify previous predictive models to improve their performance? * What is the implementation of current guideline recommendations in our country and across institutions? * What is the potential impact of deviations from current recommendations? * What is my performance compared to the rest of the thoracic surgical departments in my country in terms of perioperative and oncological outcomes? ReSECT does not consider prespecified comparison groups of patients.
