Transumbilical single-incision plus one-port laparoscopic distal gastrectomy for advanced gastric cancer

Abstract

First of all, from the lower polar of spleen to the descending duodenum, omentectomy was performed along transverse colon carefully. The right gastroepiploic vein was ligated at its root, and then No.6v lymph nodes were dissected completely. No.6a lymph nodes and No.6i lymph nodes were also dissected totally when the right gastroepiploic artery was ligated at its root. To cut the right mesogastrium at the suprapyloric area so as to transect the duodenum safely, and then No.5 lymph nodes were dissected when the right gastric artery (RGA) was ligated at its root. No.8a and No.12a lymph nodes were also dissected in en-bloc while the portal vein behind the common hepatic artery was protected safely. No.9, No.7 and No.11p lymph nodes were dissected entirely around celiac artery, left gastric artery and proximal splenic artery respectively. In addition, No. 1 and No.3 lymph nodes were dissected clearly along the lesser curvature of stomach, and No. 4sb lymph nodes were dissected when the left gastroepiploic vessels were ligated at their roots. Finally, Billroth II gastrojejunostomy and jejunojejunostomy were performed intracorporeally. Key words: Gastric cancer; Single-port laparoscope; Gastrectomy
