In recent 10 years，transumbilical single-port laparoscopic technique has been basically active in cholecystectomy，appendectomy and fenestration and drainage of hepatic cysts. However，transumbilical single-port laparoscopic partial splenectomy has rarely been reported at home and abroad. Up to now，our team has completed more than 1 000 cases of various types of single-port laparoscopic surgery，and can skillfully complete complex operations such as laparoscopic partial splenectomy and transumbilical single-port laparoscopic left hemiliver resection without auxiliary pore，which provides enough safety guarantee for the implementation of transumbilical single-port laparoscopic splenectomy. In order to explore a new approach to further reduce abdominal trauma and promote rapid recovery of patients，the team attempted a partial splenectomy with a single port transumbilical laparoscope and performed video recordings. This video shows the procedure of a partial splenectomy without any auxiliary channels and without drainage tube.
