Gastric cancer is one of the most common cancers in Korea and the world. Since 2004, this is the 4th gastric cancer guideline published in Korea which is the revised version of previous evidence-based approach in 2018. Current guideline is a collaborative work of the interdisciplinary working group including experts in the field of gastric surgery, gastroenterology, endoscopy, medical oncology, abdominal radiology, pathology, nuclear medicine, radiation oncology and guideline development methodo

The mean age of patients with gastric cancer has increased during the past 20 years. The proportion of early gastric cancer and overall survival have gradually increased, especially in patients aged over 40 years.

The seventh system provided a more detailed classification of prognosis than the sixth system, especially between T2 and T3 tumors and N1 and N2 tumors, although further studies were found to be needed for the N3a and N3b classification.

The relationship between NexLN and survival is probably affected by stage migration in a high-volume gastric cancer center. The LN ratio system could be a better option to compensate for this effect, and the value of the prognosis prediction in this system increases with a higher NexLN.

Before applying limited treatment for EGC, a surgeon should consider the risk factors of underestimation of T stage with EGD or S-CT.

There are two major stage classification systems for gastric cancer: the tumor-node-metastasis (TNM) stages by the International Union against Cancer (UICC) and the Japanese Classification of Gastric Carcinoma by the Japanese Gastric Cancer Association (JGCA). Preoperative stage classification using either of these systems is essential for deciding on the treatment strategy in the era of various multimodal therapeutic options.

The correlation between bevel direction and location of the thoracic epidural catheter was relatively low. Practices such as threading an epidural catheter by manipulation of the Tuohy needle for the control of pain at a distant site may not yield good results.

The surgical outcomes of DPLDG and TPLDG did not differ. Regarding fewer incisions, DPLDG can be an alternative option for TPLDG.

Purpose: For easy application to targeted area or in laparoscopic surgery, proper injectable antiadhesive agents are needed. The efficacy of two injectable antiadhesive agents-the thermosensitive poly (organophosphazene) hydrogel (Gel group) and a mixed solution of hyaluronate and carboxymethyl cellulose (Guardix-sol (R), Hanmi Medicare, Korea; Gd group) were compared with that of a positive control (one established membranous agent [Interceed (R), Johnson & Johnson, USA; IC group])
