[Prevention and treatment for complications in the application of new technology for stomach cancers].

With the rapid advancement of minimally invasive new technology, laparoscopic surgery and robotic surgery are now regarded as the main direction in surgical treatment for stomach cancers. Recent evidence has confirmed the safety and feasibility of laparoscopic surgery for early gastric cancer and advanced gastric cancer. However, gastrointestinal surgeons should pay more attention to complications after laparoscopic gastrectomy because of rich blood supply, complex tissue layers and lymph node metastasis. Common complications related to laparoscopic surgery are associated with laparoscopic instruments and operating, intra-abdominal bleeding, anastomotic leakage, anastomotic bleeding, pancreatic leakage, duodenal stump leakage, lymphatic leakage and so on. This article mainly focuses on the causes, prevention and treatment of the complications after laparoscopic gastrectomy.
