It is one of the main clinical manifestations of intestinal obstruction, which means that the intestine is “blocked” and the contents of the intestine cannot pass through smoothly, accumulating more and more in the gastrointestinal tract and making the intestine more and more distended, causing various systemic crises. And if frequent paroxysmal colic around the umbilicus occurs, you should be more alert.
Extra-intestinal causes: adhesions and adhesion zone compression Adhesions can cause intestinal folding and twisting and cause obstruction. Congenital adhesions are more common in children; adhesions from abdominal surgery or intra-abdominal inflammation are the most common cause of intestinal obstruction in adults, but in a few cases there may be no history of abdominal surgery or inflammation; incarcerated external or internal hernia; intestinal torsion is often due to adhesions; extra-intestinal tumor or abdominal mass compression.
Causes of the intestinal canal itself: congenital stenosis and closed-hole malformations; stenosis due to inflammatory tumor anastomosis surgery and other factors. For example, inflammatory bowel disease, intestinal tuberculosis, radiation injury, intestinal tumors (especially colon tumors), intestinal anastomosis, etc.; intestinal stenosis is less common in adults and is mostly caused by polyps or other intestinal lesions.
Intra-intestinal causes: Intestinal obstruction due to masses of roundworms foreign bodies or fecal masses etc. is no longer common. Cases of large gallstones entering the intestinal cavity through the gallbladder or common bile duct-finger fistula, producing gallstone intestinal obstruction, have been reported.
