Gallbladder cancer is a common cancer. If the symptoms of this disease are not treated in time, it is extremely detrimental to the patient’s condition. Experts remind us that medical technology is developing rapidly nowadays, such as minimally invasive therapy, which is not only effective, but also will not bring any harm to our patients. Most of them are found during surgery or pathological examination of the resected gallbladder specimen. In recent years, “B” type ultrasound examination is widely used to detect gallbladder cancer when examining patients suspected of having gallbladder disease or conducting health screening, and the images of which are diffuse irregular hypoechoic thickened areas in the gallbladder wall, parenchymal light masses in the gallbladder but no echogenic shadow. Shadow, calcification in the gallbladder wall, and can show the spread of gallbladder cancer. What is the best treatment for gallbladder cancer? Pay attention to the combined use of diet and minimally invasive therapy can surely achieve good results. Complications include pus accumulation and perforation of gallbladder infection, subphrenic abscess of liver abscess, pancreatitis, intestinal obstruction of portal vein thrombosis, bleeding in gastrointestinal tract and abdominal cavity, etc. It is also difficult to detect cancer species in early stage, so the resection rate is low, and even less of them are radical. After cholecystectomy for gallbladder stone or acute cholecystitis, gallbladder cancer is accidentally found in pathological section, and the lesion is limited to the wall of gallbladder, so most scholars advocate that it is not necessary to perform extended radical surgery because it cannot change the survival rate and prognosis. 2.For those who are clearly diagnosed as gallbladder cancer during surgery and can still be removed. How to treat gallbladder cancer well can consider resection of gallbladder and its surrounding liver tissues, and removal of lymphatic drainage area of gallbladder and lymphatic fatty tissue of hepatoduodenal ligament. 3. If the cancer has spread to the bile ducts and most of the intrahepatic metastases are not curable, palliative surgery can be done to relieve the patient’s symptoms, such as external bile duct drainage for obstructive jaundice to relieve jaundice and skin itching; gastrojejunostomy for pyloric obstruction, etc. Radiotherapy and chemotherapy are seldom effective. The prognosis of gallbladder cancer is poor, and the overall survival rate of gallbladder cancer treatment is less than 1% within 5 years, and most patients die within 1 year after diagnosis. Even the long-term survivors of incidental findings after gallbladder cancer resection are quite few. In case of gallbladder carcinoma in situ, the 5-year survival rate after cholecystectomy is about 10.6 to 22.7%. Always, for how to treat gallbladder cancer well, it is difficult to achieve the ideal effect by simple treatment. Through diet and reasonable application of various aspects, it is very beneficial to our patients’ condition.
