Description

Gastric cancer poses a significant public health problem. It is one of the most common cancers in Vietnam . Despite recent advances in multimodality treatment and targeted therapy, surgery remains the first option of treament for this disease. For resectable gastric cancer, complete removal of macroscopic and microscopic lesions and/or combined resections and also regional or extended lymphadenectomy should represent in the world now. Since laparoscopic gastrectomy for early gastric cancer (EGC) was firstly reported in 1994 , this technique has become standard for treatment of EGC due to the many advantages of mininally invasive surgery and also in oncologic outcomes.

Laparoscopic gastrectomy for advanced gastric cancer AGC was first applied by Uyama in 2000, and then, many surgeons have used it for treatment of AGC, especially in Japan, Korea and China. However, the real role of laparoscop for treament of (AGC) is still controversial in term of technical feasibility, safety and oncologic aspect.

Paragastric inflammatory strands may occur in T4a tumor so that laparoscopic technique is difficult to radically perform. Peritoneal seeding of malignant cells, intra- and postoperative complications, trocarts metastasis may risk during procedures. Despite, some studies have demonstrated the safety and the short-term benefits of LG for T4a gastric cancer, the number of these studies and sample sizes have been still inadequate to give good evidence for applying it. and long-term oncologic outcomes

There are more than 75% of patients with gastric cancer who are diagnosed in advanced stage in Vietnam, most of cases in T4a. The purpose of this study is to compare the technical feasibility, early and long term outcomes of open and laparoscopic distal gastrectomy for gastric adenocarcinoma in T4A stage.
