Prevention and management of complications in robotic radical gastrectomy

With the extensive development of minimally invasive technology in gastric cancer surgery，Da Vinci robot-assisted radical gastrectomy has also attracted increasing attention. The application of robotic technology in gastric cancer surgery can not only complete the endoscopic reconstruction of digestive tract，but also has the advantages of less intraoperative bleeding and more thorough lymph node dissection. However，the new technology cannot avoid complications and technical difficulties. The incidence of complications related to robotic gastric cancer surgery is one of the effective indicators to evaluate its safety and feasibility. Common complications of robotic radical gastrectomy mainly include abdominal hemorrhage，abdominal infection，anastomotic complications，postoperative ileus，duodenal stump fistula，pancreatic fistula and pancreatitis，pneumoperitoneal-related complications，and complications related to trocar puncture and auxiliary incision. strict adherence to the indications for robotic radical gastrectomy and careful operation by surgeons with extensive experience in robotic operation do not increase the incidence of complications and conversion to laparotomy. The purpose of this paper is to summarize and analyze the common complications found in the clinical practice of Da Vinci robot-assisted radical gastrectomy，and summarize the current effective measures for the prevention and treatment of such complications，so as to provide references for clinical work.
