Patient: Hello, doctor! I was diagnosed with gallbladder stones in September 2008, 18mm*16mm, and I have been having mild biliary colic occasionally for more than a year. The ultrasound showed that the gallbladder was slightly enlarged, with an anterior and posterior diameter of 37mm, the wall of the gallbladder was slightly rough, and a strong echogenic cluster with a size of about 26mm*19mm was visible within it, with a sound shadow behind it, which could be moved by changing the position. Can I do without surgery like this? If the surgery is laparoscopic cholecystectomy or fiberoptic choledochoscopy for biliary stone extraction is better? Will stones grow back after biliary lithotomy? What harm does laparoscopic cholecystectomy do to my body? I read that there is a high risk of colon cancer after gallbladder removal? Can it also cause diarrhea? Thank you! Doctor: Your diagnosis is clear and your symptoms are obvious, I personally think you need surgery. As you mentioned, there are 2 kinds of surgical treatment methods: laparoscopic cholecystectomy and fiberoptic choledochoscopy for biliary stone extraction.
