Patient: My beloved, 32 years old, started to have abdominal pain two months after cholecystectomy, usually after eating a good meal for more than an hour, gradually increasing, more difficult to bear, and then relieved by itself, lasting about half an hour, with attacks every three or four days, without acid reflux, belching, jaundice between attacks. I have been taking Loxacol orally, but it is not effective. What is this disease and how should I treat it? What medicine should I use? What should I pay attention to in my diet? The B ultrasound examination did not show any abnormalities Hepatobiliary Surgery Department of Liver and Gallbladder Hospital: abdominal pain after cholecystectomy is generally called post-cholecystectomy syndrome, common causes are: sphincter of Oddi dysfunction upper peptic ulcer biliary tract residual stones and so on. If the patient had abdominal pain before surgery and it was only gallbladder polyps or simply cholecystitis without clear gallbladder stones, we should consider whether the abdominal pain was caused by peptic ulcer rather than gallbladder, and gastroscopy and biliary excretion test should be done. If there is no preoperative pain, then we should consider whether there are intestinal adhesions or gastrointestinal dysfunction; in short. The cause of abdominal pain should also be clarified.
