Transverse colitis is located in the transverse colon.
If you are asking about the location of abdominal pain due to transverse colitis, let's first understand the anatomical position of the transverse colon. The ends of the transverse colon are located under the spleen and the liver. During a colonoscopy, when passing through the hepatic flexure or splenic flexure, cystic spots are often found, which are shadows of the liver and spleen. Generally, in patients who are short and stout, the internal abdominal fat tends to hold the free transverse colon relatively fixed, arranging it in a straight line like the Chinese character "一". For thin and frail patients, lacking support, the transverse colon can sag. In patients who have had abdominal surgery, the intestinal structure may be disordered. Therefore, the abdominal pain associated with transverse colitis generally centers around or below the umbilicus on either side.
