Gallbladder polypoid lesion 0.3*0.2cm treatment has drug treatment, surgical treatment, general treatment. 1. Drug treatment: commonly used drugs include ursodeoxycholic acid capsule, which is used to regulate the metabolism of cholesterol and bile acid salts. 2. Surgery: For patients with polyps larger than 10mm, cholecystectomy is required because of the increased risk of malignancy. 0.3cm*0.2cm gallbladder polyps generally do not require treatment, unless malignancy is highly suspected, surgical treatment can be considered. Surgical procedures include laparoscopic cholecystectomy and open cholecystectomy. (1) Laparoscopic cholecystectomy: the gallbladder is removed directly under laparoscopy, and the polyp is sent for pathologic biopsy. This method is less traumatic, shorter recovery time, fewer complications. (2) Open cholecystectomy: direct removal of the gallbladder through open abdomen. 3. General treatment: regular meals, moderate meals, weight loss. (1) Eating on time: develop the habit of eating on time to promote the rhythm of bile secretion. (2) Moderate meals: avoid bile secretion in large quantities, so that the contraction of bile is rhythmic. (3) Weight loss: allow cholesterol to be metabolized normally to avoid deposition. If gallbladder polyps appear, it is recommended to consult a doctor in time and standardize the treatment under the doctor’s guidance.
