1. The role of the ileocecal valve in obstruction of the colon
The role of the ileocecal valve in obstruction of the colon. The obstruction is in the upper sigmoid. A: The ileocecal valve is competent, creating a closed loop between the obstruction and the valve. Tension in the closed loop is increased further by emptying of gas and fluid from the ileum into the colon. B: The ileocecal valve is incompetent. Reflux into the ileum is permitted. The colon is relieved of some of its distention, and the small bowel has become distended.
