hi. thanks for posting query at HCM. read your question thoroughly and understood your concern. differential: surgical incision pain, fat intolerance/ gastritis or stone remnants in common bile duct. as per your presentation, ultrasound abdomen is normal , so stones in common bile duct has been ruled out and the tissue underlying incision maybe normal . Scar tissue formation constricting small intestine is very UNLIKELY in your scenario. gall bladder primary role is to store bile . when gall bladder is intact, bile is usually secreted after having a meal rich in fat; bile plays a vital role in fat digestion. after gall bladder is removed, bile is continuously being secreted in small intestine and may reflux into stomach. as a result, gastric inflammation may occur causing pain and discomfort. moreover, high fat meal induces more bile synthesis - further affecting gastric mucosa as well as bile is less concentrated and drains more continuously into the intestines, where it can have a laxative effect and some patients may develop diarrhea. advise: NO fat intake or decreased fat intake few weeks trial of OTC proton pump inhibitor (omeprazole/pantoprazole)to combat gastritis ( after discussing with treating physician) mebeverine maybe used for cramping pain small meals Add soluble fiber, such as oats and barley, to your diet. But be sure to increase the amount of fiber slowly, avoid dairy products and caffeine hope to answer your concern wish you good and sound health. regards Dr Tayyab Malik
