Cecal Bascule
Cecal bascule is a cause of large bowel obstruction where there is folding of the cecum anteriorly over the ascending colon. It is one of two types of cecal volvulus, the other being axial ileocolic. It is caused by rotational torsion of the cecum or ascending colon along its own axis. In cecal bascule, the base of the cecum folds anteriorly over the ascending colon, creating a flap-valve, obstructing emptying of the cecum. The condition can be complicated by necrosis or organ perforation before the diagnosis is made, particularly if the ileocecal valve is competent, preventing retrograde decompression of the cecum into the ileum The ileum () is the final section of the small intestine in most higher vertebrates, including mammals, reptiles, and birds. In fish, the divisions of the small intestine are not as clear and the terms posterior intestine or distal intestine ma ....{{Cite journal , last1 = Pousada , first1 = L. , title = Cecal bascule: An overlooked diagnosis in t ...

Large Bowel Obstruction
Bowel obstruction, also known as intestinal obstruction, is a mechanical or functional obstruction of the intestines which prevents the normal movement of the products of digestion. Either the small bowel or large bowel may be affected. Signs and symptoms include abdominal pain, vomiting, bloating and not passing gas. Mechanical obstruction is the cause of about 5 to 15% of cases of severe abdominal pain of sudden onset requiring admission to hospital. Causes of bowel obstruction include adhesions, hernias, volvulus, endometriosis, inflammatory bowel disease, appendicitis, tumors, diverticulitis, ischemic bowel, tuberculosis and intussusception. Small bowel obstructions are most often due to adhesions and hernias while large bowel obstructions are most often due to tumors and volvulus. The diagnosis may be made on plain X-rays; however, CT scan is more accurate. Ultrasound or MRI may help in the diagnosis of children or pregnant women. The condition may be treated conservati ...
