Chinese medicine Enema is one of the external therapies in Traditional Chinese medicine(TCM), which has been widely used clinically. The "International Standard of Traditional Chinese medicine Techniques: The Operating Specifications for Chinese medicine Enema is drawn up by the Beijing Hospital of Traditional Chinese medicine affiliated to Capital Medical University and Beijing University of Chinese medicine Xiamen Hospital in collaboration with domestic TCM universities and hospitals. The specification includes definition, operating process, points for attention and contraindications. It is targeted to provide reference for TCM providers at home and abroad with TCM background in clinical decision-making.

Retroaortic left renal vein associated to variations of liver vasculature and biliary system in a patient submitted to total pancreatectomy

Hepatobiliary & Pancreatic Diseases International 2024年第5期23卷 526-529页

作者： Alessandro Fancellu Mario Maiore Lavinia Grasso Miriam Ferrara Alberto Porcu department of medicine Surgery and PharmacyUnit of General Surgery 2-Clinica ChirurgicaUniversity of SassariSassari 07100Italy department of medicine Surgery and PharmacyUnit of RadiologyUniversity of SassariSassari 07100Italy

Total pancreatectomy(TP) is a surgical procedure which includes the complete removal of the pancreatic gland, the spleen, the duodenum, the gallbladder, and the distal part of the stomach. TP represents the curative treatment of pancreatic cancer which simultaneously involves the head and the body/tail of the pancreas. Other possible indications for TP comprise multifocal parenchymal diseases, such as intraductal papillary mucinous neoplasms, pancreatic neuroendocrine tumors, multiple endocrine neoplasms, and chronic pancreatitis. Sometimes, TP is carried out in patients scheduled for pancreaticoduodenectomy(where only the head of the pancreas is removed) when a cancer located in the pancreatic head is intraoperatively found to also extend to the pancreatic body [1].
