Core Tip

Core tip: Laparoscopic and endoscopic cooperative surgery (LECS) was first described as a treatment of gastric submucosal tumors in 2008, although a similar concept had been developed before that time. Thereafter, many researchers described LECS as a feasible technique for gastric resection, regardless of tumor location. LECS is a novel procedure that minimizes invasive damage to patients and preserves physiologic function of the residual stomach while securing oncological benefit. Currently, many physicians can fully utilize the advantages of LECS for gastric submucosal tumors located even at the esophagogastric junction by avoiding conventional total gastrectomy or proximal gastrectomy. This technique requires close cooperation between skilled surgeons and experienced endoscopists. Therefore, many tips and pitfalls should be discussed to accelerate this collaboration during LECS. We hope that the herein-described tips will benefit laparoscopic surgeons and interventional endoscopists who are interested in LECS.
