Gallbladder polyps are a common disease with high incidence in the population, with fewer clinical manifestations and mild symptoms, which are difficult to detect and often found through routine physical examinations. Can gallbladder polyps become cancerous? How to treat gallbladder polyps after they are found? It is a question that most of us are concerned about. Can gallbladder polyps become cancerous? In fact, most of the polyps are benign, but a small percentage of gallbladder polyps may become cancerous. Which polyps need to be alerted to the possibility of cancer? Polyps with the following conditions need to be alerted to the possibility of cancer: polyps with diameter of 10mm or more; rapid growth of polyps in a short period of time; combined with gallbladder stones; age over 50 years; wide base; single polyps are more likely to become cancerous than multiple polyps. Do I need surgery to find gallbladder polyps? In fact, not all gallbladder polyps need surgery, it depends on the size of the polyps and the symptoms to decide. It can be divided into conservative treatment and surgical removal. Conservative treatment includes treatment of the primary disease, medication and regular follow-up. The etiology of gallbladder polyps is still not well understood, and no targeted treatment is available. Gallbladder polyps may be associated with chronic cholecystitis, gallbladder stones and disorders of cholesterol metabolism. Obesity, smoking, hyperlipidemia, hyperinsulinemia, liver cirrhosis, anatomical abnormalities of the upper gastrointestinal tract and biliary tract are the factors that favor gallbladder polyps, and the prevention and treatment of these diseases should be actively done. Medication, there is no clear effective treatment for gallbladder polyps, oral choleretic drugs or Chinese medicine, may have the effect of improving symptoms, and can not eliminate gallbladder polyps. The most important thing for the conservative treatment of gallbladder polyps is regular follow-up, usually choose ultrasound as the preferred method of follow-up examination. For which types of gallbladder polyps can conservative treatment be chosen? Which types must be surgically removed? How to develop a follow-up strategy for patients who need follow-up? For patients with gallbladder polyps less than 5mm in diameter and without obvious clinical symptoms, ultrasound can be checked once every 1 year, if the polyps do not grow, ultrasound follow-up can be continued annually, if the polyps grow during the follow-up process, the follow-up interval can be further shortened by 3-6 months. Meanwhile, if the diameter of gallbladder polyps is less than 5 mm and accompanied by postprandial right upper middle abdominal pain, and confirmed to be associated with gallbladder stones, common bile duct obstruction, recurrent pancreatitis, etc., surgery is recommended. Care should be taken to distinguish symptoms of gastritis or functional dyspepsia such as upper and middle abdominal pain and abdominal distention, which cannot be an indication for surgical treatment. For patients with gallbladder polyps between 5-10 mm in diameter and without obvious clinical symptoms, it is recommended to check ultrasound every 6 months and continue follow-up if the polyps do not increase in size. If the polyp continues to increase in size and exceeds 10 mm, surgery is recommended. If asymptomatic, but older than 50 years old and with gallbladder stones, surgery is still recommended. Surgery is also recommended if the polyp is between 5-10 mm in diameter and is associated with postprandial right upper middle abdominal pain and is confirmed to be associated with associated gallbladder stones, common bile duct obstruction, recurrent pancreatitis, etc. Care should be taken to distinguish symptoms of gastritis or functional dyspepsia such as upper and middle abdominal pain and abdominal distention, which cannot be an indication for surgical treatment. For patients with gallbladder polyps larger than 10 mm in diameter, surgical treatment is recommended regardless of whether they have symptoms or not, especially if the gallbladder polyp is found to be 20 mm or larger on examination, surgical treatment should be performed as soon as possible.
