RESUMO
With the development of laparoscopic surgery for gastric cancer, more and more surgeons use laparoscopic techniques and even totally laparoscopic techniques in gastric cancer surgery. However, technological progress brings not only smaller trauma, but also new problems and risks. Compared with traditional open surgery, the high incidence of internal hernia after laparoscopic gastric cancer surgery is an urgent problem to be solved. As the incidence of internal hernia often occurs after discharge, patients usually choose the nearest hospital for diagnosis and treatment due to the urgent course of disease. As a result, patients with internal hernia often have serious complications due to delayed treatment because of the difficulty in diagnosis. Sometimes, there are patients even death. The authors review the relevant research on postoperative internal hernia of gastric cancer in recent years and combine with practical experience to discuss the diagnosis and treatment strategy of internal hernia after laparoscopic surgery for gastric cancer, aiming to improve the clinicians′ attention to the disease and provide reference for its diagnosis and treatment.
