[Problems and strategies of laparoendoscopic single site surgery in gastrointestinal surgery]

Laparoendoscopic single site surgery(LESS), which has been applied in gastrointestinal surgery domestically and abroad, is the most feasible "scarless" operation at present. Combined with our expierience the problems and strategies of laparoendoscopic single site surgery in gastrointestinal surgery are reviewed and discussed in this paper. Inline vision, chopsticks effect and equipment congestion are the difficulties in LESS, especially when it is used in gastrointestinal surgery. Improving skills, selecting appropriate apparatus, fixed operating team and flexible exposure method can ensure the safety of LESS. In order to ensure that LESS is accepted, the safety and effectiveness of LESS used in the operation of gastric and colorectal cancer need assessment. As a new surgical technique, the further development of LESS in gastrointestinal surgery is not possible without concept recognition, breakthrough of technical limitation and equipment innovation.
