ileocecal valve syndrome
Introduction
Introduction to ileocecal valve syndrome The ileocecal valve syndrome (ileocecalvalvesyndrome), also known as ileocecal sphincter syndrome, refers to non-specific edema of ileocecal valves caused by various causes. The clinical manifestations are 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 ileocecalvalve prolapse syndrome (also known as ileocecal valve hyperlipidemia). basic knowledge The proportion of illness: 0.003% Susceptible people: good for young adults and obese women Mode of infection: non-infectious Complications: diarrhea
Cause
Causes of ileocecal valve syndrome
Rigler summarizes the intrinsic causes into five categories:
1 edema: idiopathic or injurious;
2 ileal mucosa invaded or prolapsed into the colon;
3 submucosal fat accumulation;
4 ilerous department, malignant tumor;
5 inflammation involving the ileocecal valve: parasitic (Amoeba), non-specific (Crohn's disease).
The ileocecal valve of this disease is hyperemia, edema, hypertrophy and other changes, and some even have scar formation. Due to ileocecal lesions, the ileocecal sphincter reflex activity is hyperthyroidism, resulting in the sphincter spasm or hyperplasia, and the end ileum needs to strengthen activities. Overcoming the resistance, resulting in increased ileal peristalsis, accelerated intestinal contents, abdominal pain, diarrhea and other symptoms, Smith believes that ileocecal valve hypertrophy can be diffuse lipoma infiltration.
Prevention
Ileocecal valve syndrome prevention
Due to the abnormal structure of the congenital ileocecal valve, it is difficult to prevent. Early detection, early diagnosis and early treatment are the key to the prevention and treatment of this disease.
Complication
Complications of ileocecal syndrome Complications, diarrhea
Diarrhea, right lower quadrant mass, rectal bleeding.
Symptom
Symptoms of ileocecal valve syndrome Common symptoms Lower abdominal pain constipation Intestinal bleeding Diarrhea Appetite loss Abdominal edema ileocecal insufficiency Tension right lower quadrant tenderness
The main symptoms are recurrent diarrhea, right lower quadrant pain, weight loss, but also loss of appetite, abdominal distension and other symptoms of digestive dysfunction, signs of right lower quadrant tenderness, but no rebound pain and muscle tension.
Because of ileocecal valve prolapse, diarrhea and constipation often appear alternately, the right lower abdomen can touch the mass, or with varying degrees of rectal bleeding.
Examine
Examination of ileocecal valve syndrome
(A) blood test: white blood cells are basically normal.
(2) Barium enema examination: typical filling defects can be seen in the ileocecal valve area, which are rose-like, cap-shaped, scorpion-like, umbrella-shaped, etc., with partial tenderness, and the anterior image defect is smooth and round.
(C) fiber colonoscopy: an important means of examination, inserted into the ileocecal area, can observe the shape of the ileocecal valve under direct vision.
Diagnosis
Diagnosis and identification of ileocecal valve syndrome
diagnosis
Diagnosis can be based on medical history, clinical symptoms, and laboratory tests.
Differential diagnosis
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, need laparotomy to confirm the diagnosis.
