SAT vs Escitalopram for Rectal Hypersensitivity

Summary

Constipation is a common digestive disorder. After excluding dietary factors, drugs and other secondary causes, at least three broad pathophysiologic subtypes are recognized- dyssynergic defecation, constipation-predominant irritable bowel syndrome (IBS-C) and slow transit constipation (STC), all predominantly affect women and elderly. Many patients also demonstrate abnormal rectal perception with both rectal hyposensitivity and hypersensitivity being common. Recent surveys show that most constipated patients are dissatisfied with current therapy. Also, constipated patients showed significant psychological dysfunction and impaired quality of life. OBJECTIVE: To investigate a novel biofeedback technique of improving rectal hypersensitivity. METHODS: A large compliant balloon attached to a barostat was placed in the rectum in 8 patients with rectal hypersensitivity (urgency/pain threshold \<30 mm Hg). Sensory deconditioning was performed by incremental balloon distensions (1-2 mmHg) until normal thresholds were reached.
