In the past, the function of the gallbladder was not well understood, except for the function of concentration and contraction, it was only a bile storage organ and was not valued or even considered dispensable. Therefore, gallbladder removal was not a matter of debate. With the progress and development of science and technology in recent years, a large number of clinical reports on various maladies after cholecystectomy have revealed that the gallbladder has complex and extremely important functions and is indispensable and irreplaceable. With the modern medical exhibition, there is a further understanding of the gallbladder as an important digestive organ, which is a complex organ of chemical and immunological functions, in addition to its role of concentration, contraction and regulation of buffering biliary pressure. It is not a dispensable gallbladder, but a very important digestive organ, so it should not be easily abolished! Of course, for those who have an atrophied gallbladder, whose gallbladder is no longer functional, or whose gallbladder is suspected of being cancerous, the gallbladder should undoubtedly be removed to remove the lesion.
