Diagnosis and management of adult patients with chronic intestinal pseudoobstruction

Chronic intestinal pseudoobstruction (CIP) is a motility syndrome that presents with symptoms and signs of intestinal obstruction and radiographic evidence of dilated bowels, but no anatomic obstruction can be found. It primarily is a disorder of small bowel motility, but it can occur anywhere in the gastrointestinal tract. This review will focus on the diagnosis and treatment of adult patients with CIP. The clinical presentation of CIP is variable, and its incidence is rare. It is a disorder with a multitude of etiologies, many of which are poorly understood. To properly manage the patient, clinicians should be aware of the various symptoms, signs, and systemic diseases that are associated with CIP. Diagnostic studies are needed to confirm the diagnosis, identify the etiology, and search for coexisting motility dysfunction. The management goals of CIP are to restore proper nutrition and fluid balance, relieve symptoms, improve intestinal motility, and treat complications.
