Study On The Operation Of Non-vessel Fistula Of Black Bear

Black bears are an important component of Bear Resources in China,and have also been called moon bear, Himalayan bear, or Tibetan Bear. Black bears are one of the economically valuable medicinal animals, their bones, meat, palm, grease, blood, brains can be used as medicine. But the most valuable is bear bile. The bear’s gall is the dry bile-cyst of the black bear or brown bear in the tradition clover shrub, named copper gall, sider-gall and cauliflower gall. Bear bile is a precious Chinese herbal medicines, commonly known as the King of gall, is more than60kinds of proprietary Chinese medicine raw materials. The gall powder is obtained from the bear though the technique of the artificial drainage.The keeping of bear in our country begins from1984, and the technique of taking the gall was from North Korea.1985—1990, it appeared the gall of bear powder from artificial farming bears because it is critical shortage of the wild gall of bear, and the price than the wild gall of bear is low. In this stage nation still without wildlife conservation method, and develop of bear breeding was abnormally quick at that time.1993—2001, the main purpose of the garden farming black bear was gall of bear powder, in addition to breed and appreciate were the main earnings method for some farms. The gall of bear powder flies to export, making patent medicine etc. The product which uses gall of bear powder has results to show medicine, pure gall of bear powder bag, health care article and other products.In this period, the farms used an outrageous method namely the method of "iron vest" to collect gall of bear juice in order to obtain gall of bear powder, which subjected to trampling upon of severity on the bear’s body and spirit. Bile obtaining technical of tube bile causing a lot of diseases, have a serious impact on the bear’s health, longevity and bile quality, were given the strong opposition of the international conservation organizations. In response to this situation, the current Bear bile, bile surgery to replace the tube drainage to take the gall bladder surgery more no-tube drainage, but the individual bear farms also insisted tube drainage bile surgery. Although ductless bile method overcomes the drawbacks of tube drainage of bile, but also give rise to take the biliary stricture, repeat surgery and other defects. The purpose of the study is to overcome the defects of the existing technology, innovation to take a permanent biliary ductless bile surgery to a new stage.The method of non-vessel fistula operation for collecting the gall of bear in recent years is accepted by the large wildlife fancier towards collecting biliary bear to injure smallerly. We described the surgical operation’s method in details in surgical equipment, medicines, preoperative preparation, surgical technique, postoperative care and bile collection and processing detailed description of the surgical methods, and carried on the operation in a bear garden. We also have maken a follow-up visit and observation to the bear, and have not discovered other exceptional responses. The bear started the regular production in the latter21days of the surgery.Through the experiment, we have grasped the technique of artificial bear’s gall drainage non-vessel fistula to be advanced, completed and detailed.
