Abstract

BACKGROUND AND OBJECTIVES:

The diagnostic yield of push enteroscopy (PE) varies widely from 13 to 78% of cases, according to the various series. The aim of this retrospective cohort study was to determine the endoscopic and histological yield of PE in our health area.

PATIENTS AND METHODS:

A total of 355 consecutive patients (190 males/165 females; mean age 45 years, range 15-89) underwent PE over a 6-year period, from 1997 to 2003. PE was performed under sedation and without overtube. Small-bowel mucosa biopsies were taken in 199 explorations (56%). Clinical indications for PE included: chronic diarrhea (35%), occult digestive bleeding (ODB) or iron-deficiency anemia (28%), suspected small-bowel malignancy (16%), chronic abdominal pain (28/355; 8%), follow-up of polyposis or malabsorption syndromes (7%), and abnormal radiographic findings (6%).

RESULTS:

PE detected lesions in 122 cases (34%); in 6 cases (6%) lesions were within the reach of esophagogastroduodenoscopy. A normal macroscopic appearance of the small intestinal mucosa with an abnormal histological study was seen in 16 patients (6%). Major findings included: malabsorptive diseases (14%), nonspecific enteropathy (5%), angiodysplasia (3,5%), lymphangiectasia (3%); jejunal polyps (2%), Crohn s disease (2%), intestinal tumors (2%), extrinsic jejunal strictures (0.5%), and other (10/355; 3%). Abnormal radiographic findings (62%), chronic diarrhea (37%) and ODB (31%) were the indications with a higher diagnostic yield. No major complications were seen.

CONCLUSIONS:

According to our experience, PE is a safe and useful tool for the evaluation of small-bowel disease, especially in some indications (abnormal radiographic findings, chronic diarrhea, and ODB). Small-bowel biopsy increases PE's diagnostic yield in patients with chronic diarrhea.
