Ileocecal valve insufficiency

Introduction The clinical manifestation of ileocecal valve dysfunction is ileocecal valve syndrome. The ileocecal valve syndrome is also known as the ileocecal sphincter syndrome. Refers to non-specific edema of ileocecal valves caused by various causes. Clinical manifestations include repeated diarrhea, right lower quadrant pain, and weight loss. Young adults and obese women are more common. If the ileocecal valve and the prominent ileal mucosa together into the cecum, it can be called ileocecal valve prolapse syndrome (ileocecal valve prolapse syndrome), also known as ileocecal hyperlipidemia.

Cause

Rigler summarizes the intrinsic causes into five categories: 1 edema: idiopathic or injurious. 2 ileal mucosa invades or prolapses into the colon. 3 submucosal fat accumulation. 4 ilerous, benign, malignant tumors. 5 inflammation involving the ileocecal valve: parasitic (Amoeba), non-specific (Crohn disease).

The ileocecal valve of this disease is characterized by congestion, edema, hypertrophy, and some even have scar formation. Due to ileocecal lesions, the ileocecal sphincter reflex activity, resulting in sphincter spasm or hyperplasia, the end ileum needs to strengthen activities, in order to overcome its resistance, resulting in increased ileal peristalsis, accelerated intestinal contents, abdominal pain, diarrhea, etc. symptom. Smith believes that ileocecal valve hypertrophy can be diffuse lipoma infiltration.

Intrinsic non-specific clinical manifestations, easy to be confused with chronic appendicitis, diagnosis often requires X-ray barium enema examination, or fiber colonoscopy to find typical ileocecal valve changes. A small number of patients require a laparotomy to be diagnosed.

The main symptoms are recurrent diarrhea, pain in the right lower quadrant, and weight loss. There may also be symptoms of digestive disorders such as loss of appetite and abdominal distension. Signs have tenderness in the right lower quadrant, but no rebound pain and muscle tension. Because of the ileocecal valve prolapse, diarrhea and constipation often appear alternately. The mass can be reached in the right lower abdomen, or with varying degrees of rectal bleeding.

Differential diagnosis

Differential diagnosis:

Chronic appendicitis: Chronic appendicitis refers to chronic inflammatory lesions of the appendix left after the acute inflammation of the appendix subsides, such as fibrous connective tissue hyperplasia, stenosis or occlusion of the lumen, distorted appendix, and adhesion to surrounding tissues.
