The patient has pain on pressure under the ribs in the right upper abdomen, an area of pain most often associated with gallbladder disease. In addition, diseases of the bile duct and transverse colon may also cause pain in this area. If the stool is dry or unformed, an e-colonoscopy is needed to rule out transverse colon disease. In addition, if the area is painful by pressure, gastric and duodenal diseases should be excluded, because this area is a visceral nerve pain and its localization is not very precise. If the patient has the above symptoms after eating or if the above symptoms appear to be aggravated, stomach and duodenal diseases should be considered and electronic gastroscopy should be done to clarify them.
