Benign tumors located in the tail of the pancreas can usually be accomplished by laparoscopic minimally invasive techniques due to the location of the tumor and the feasibility of surgical operation, which is accepted by the majority of patients for its advantages of quick recovery, less pain and fewer complications. Due to the immune function of the spleen, it is usually required to preserve the spleen as much as possible. There are two ways to preserve the spleen by laparoscopic preservation of the distal pancreas. The first is to remove the distal pancreas while routinely preserving the splenic vasculature and ensuring the vascularity of the spleen. If the tumor is large in size and closely related to the splenic vein and the splenic vessels cannot be preserved, the splenic artery can be cut at the section of the severed pancreas and then the splenic vessels can be removed at the splenic hilum, and the splenic vessels are supplied with blood through the short gastric vessels and the left vessels of the gastric omentum. This method was proposed by Dr. Warshaw at Massachusetts General Hospital in the United States. In 17 cases of distal pancreatectomy, the spleen was preserved using this method, and only one case of splenic infarction occurred. In our hospital, this method was used in 6 of 28 laparoscopic distal pancreatic resections with preservation of the spleen, and no splenic infarction has yet occurred. Therefore, for benign tumors in the tail of the pancreatic body, the function of the spleen should be preserved as much as possible.
