Transverse colon displacement is a manifestation of pancreatic cysts. Pseudocysts in the head of the pancreas can widen the duodenal flexure and displace the transverse colon upward or downward. Pancreatic cysts (pancreaticcyst) include true cysts, pseudocysts and cystic tumors. So, how to differentially diagnose transverse colon displacement? The following are the methods to diagnose transverse colon displacement: 1. pancreatic cancer: the main manifestations are pain in the stomach and abdomen, nausea, emaciation, jaundice, etc. The condition is heavy and deteriorates rapidly, and barium meal, CT, ultrasound and other examinations of the stomach and intestines can help to differentiate. 2.Gastric ulcer: recurrent episodes of gastric and epigastric pain, closely related to diet, periodic and rhythmic, niche shadows found in barium X-ray examination, ulcerative lesions can be seen in fiber gastroscopy, etc. 3, spleen impotence: mainly refers to malabsorption, the location of the disease is mostly in the small intestine, and can be similar to the performance of painless pancreatic distension, but the spleen impotence has obvious signs of deficiency of Ying Qi, such as anemia, low total plasma protein and cholesterol, etc. The dextrose absorption test is significantly reduced, the glucose tolerance test is low flat curve, no elevated blood sugar, negative urine sugar, etc. can be distinguished. 4, renal cyst: renal cyst (renalcyst, cystofkidney) is a general term for cystic masses of varying sizes in the kidney that are not connected to the outside world, common renal cysts can be divided into adult-type polycystic kidney, simple renal cyst and acquired renal cyst. 5, liver cysts: hepaticcyst,cystofliver, commonly known as a blister in the liver. The vast majority of hepatic cysts are congenital, that is, due to some abnormality in congenital development leading to the formation of hepatic cysts. Acquired factors are rare, such as in pastoral areas, where parasitic cysts can develop in the liver if people contract encapsulated cysticercosis. Trauma, inflammation, and even tumors can also cause liver cysts. Cysts can be solitary, just one, as small as 0 or 2 cm; or they can be as many as ten or dozens, or even one can be as large as tens of centimeters. Patients with multiple hepatic cysts are sometimes combined with cysts of other internal organs, such as concomitant renal cysts, pulmonary cysts and occasionally pancreatic cysts and splenic cysts. When persistent epigastric pain, nausea and vomiting, weight loss and fever occur after acute pancreatitis or pancreatic trauma, and a cystic mass is found in the abdomen, the possibility of pseudopancreatic cyst formation should be considered first. The following tests should be performed promptly to make the diagnosis.
