Role of minimally invasive techniques in gastrointestinal surgery:Current status and future perspectives

摘要

In recent years,the incidence of gastrointestinal cancer has remained high.Currently,surgical resection is still the most effective method for treating gastrointestinal cancer.Traditionally,radical surgery depends on open surgery.However,traditional open surgery inflicts great trauma and is associated with a slow recovery.Minimally invasive surgery,which aims to reduce postoperative complications and accelerate postoperative recovery,has been rapidly developed in the last two decades;it is increasingly used in the field of gastrointestinal surgery and widely used in early-stage gastrointestinal cancer.Nevertheless,many operations for gastrointestinal cancer treatment are still performed by open surgery.One reason for this may be the challenges of minimally invasive technology,especially when operating in narrow spaces,such as within the pelvis or near the upper edge of the pancreas.Moreover,some of the current literature has questioned oncologic outcomes after minimally invasive surgery for gastrointestinal cancer.Overall,the current evidence suggests that minimally invasive techniques are safe and feasible in gastrointestinal cancer surgery,but most of the studies published in this field are retrospective studies and casematched studies.Large-scale randomized prospective studies are needed to further support the application of minimally invasive surgery.In this review,we summarize several common minimally invasive methods used to treat gastrointestinal cancer and discuss the advances in the minimally invasive treatment of gastrointestinal cancer in detail.
