[Research progress of single-incision laparoscopic radical gastrectomy]

Gastric cancer is one of the most common malignant diseases in the world, which has a high incidence in our country and threatens people's health seriously. Laparoscopic radical gastrectomy is one of the main methods of surgical treatment for gastric cancer, whose clinical application has a history of near 30 years. With the in-depth understanding of minimally invasive surgery and the improvement of patients' cosmetic demand, single-incision laparoscopic surgery has emerged. Since the first report of single-incision laparoscopic radical gastrectomy in 2010, its safety has been preliminarily confirmed. While this result still needs to be further verified by more prospective randomized controlled studies. Compared with traditional laparoscopic radical gastrectomy, single-incision laparoscopic radical gastrectomy has the advantages of less trauma, less postoperative pain and faster postoperative recovery. So it has been favored by surgeons. However, the steeper learning curve and difficult operation of single-incision laparoscopic radical gastrectomy limit its promotion in clinical applications. At present, there are still controversies and confusions in the single-incision laparoscopic radical gastrectomy. This article elucidates the advances and existing problems of single-incision laparoscopic radical gastrectomy.
