Gastroparesis, also known as “gastroparesis”, refers to pain in the upper and middle abdomen, located below the glabella and above the navel. Most of the pain in this area comes from stomach and duodenal diseases. However, besides the stomach and duodenum, the gallbladder, pancreas, left lobe of the liver, common bile duct and heart and lungs are all close to or near the middle and upper abdomen, and lesions of these organs can also cause “stomach pain”. Besides, “stomach diseases (including stomach and duodenal diseases)” do not necessarily have “stomach pain”, for example, a considerable number of patients with chronic atrophic gastritis and functional dyspepsia only have upper abdominal fullness, belching, eructation, and dullness as the main symptoms, and often have no pain or pain is not The pain is not obvious. Even some patients with peptic ulcer and early gastric cancer have symptoms of “stomach pain” that seem to be absent. So, what diseases other than stomach and duodenum can cause “stomach pain”? 1. Biliary tract diseases. Patients with acute and chronic cholecystitis, cholelithiasis, cholelithiasis, biliary ascariasis and other biliary tract diseases have irregular vague pain and discomfort in the upper and middle abdomen and/or under the right quadrant of the ribs, and sometimes symptoms similar to gastric diseases such as upper abdominal fullness and belching can occur. The disease is often triggered or aggravated by the consumption of fatty foods, etc. Many patients have been misdiagnosed as stomach pain by themselves or doctors for a long time, and the treatment as stomach disease is ineffective. 2.Hepatobiliary malignant tumor. Such as hepatocellular carcinoma (especially left lobe hepatocellular carcinoma), gallbladder carcinoma and common bile duct carcinoma can be manifested as “stomach pain” and symptoms and signs such as upper abdominal fullness, weakness, poor appetite and jaundice, which are easily misdiagnosed as gastric disease and lose the opportunity of early diagnosis and treatment. Abdominal ultrasound, CT and gastroscopy can be used for differentiation. 3.Pancreatic diseases. Patients with pancreatic head cancer, chronic pancreatitis and pancreatic pseudocysts also often have symptoms such as vague pain in the upper and middle abdomen, nausea and vomiting, which can be easily confused with gastric disease. Abdominal ultrasound, CT and gastroscopy, blood and urine amylase and other tests can be used to differentiate. 4. Myocardial infarction. Elderly people with acute myocardial infarction, especially lower wall acute infarction, may not always have anterior precordial angina, but may only complain of “stomach pain” or middle and upper abdominal discomfort, accompanied by nausea and vomiting. Some patients will strongly request for gastroscopy, and if they are not treated blindly according to gastroscopy without ECG examination, it is easy to miss the chance of resuscitation and accident. Some patients may even die suddenly during gastroscopy, which can not fail to alert our doctors! 5. Lower lobe pneumonia. When lobar pneumonia is located in the lower lobes of the left and right lungs, the patient can have pain in the upper and middle abdomen, similar to gastric disease, but also have varying degrees of fever, cough, rust-colored sputum, wet tones on auscultation, and faint occultation on x-ray. Gastroscopy and x-ray examination can be used to differentiate. Anti-infection treatment can control the disease as soon as possible.
