腹腔镜远端胃癌D2根治术中胃周血管的解剖概要

腹腔镜手术以其显著的微创优势已成为外科医生治疗早期胃癌的首选方式之一。随着腹腔镜手术经验的不断积累，腹腔镜远端胃癌D：根治术已逐步应用于治疗进展期胃癌。然而，该术式在技术层面的要求高，尤其是在进行D2淋巴结清扫时，对于准备开展该术式的外科医生而言．术中突发的出血状况往往是阻扰他们顺利进行手术的原因之一。因此，熟练掌握胃周血管的解剖对安全有效地实施腹腔镜远端胃癌D2根治术是必需的。

Anatomy of the perigastric vessels in laparoscopy-assisted distal gastrectomy with D2 lymphadenectomy for gastric cancer

The laparoscopic approach is rapidly becoming the preferred method of treatment for patients with early gastric cancer due to advantages of minimally invasive surgery. As laparoscopic experience has accumulated, laparoseopy-assisted distal gastreetomy （LADG） with D2 lymphadenectomy has become a valuable alternative for the treatment of patients with advanced gastric cancer. However, laparoscopic gastric surgery is demanding from a technical point of view, especially when a D2 lymphadenectomy is performed. Surgeons seeking to undertake LADG are concerned about unpredictable intraoperative bleeding that may occur during LADG. Comprehensive knowledge of the perigastric vascular anatomy is essential for LADG with D2 lymphadeneetomy.
