Background: While the routine performance of terminal ileum (TI) intubation during colonoscopy procedures is perceived to have a low yield, its utility during colonoscopies performed for specific indications have not been well studied.

Objectives: To assess the diagnostic yield of an indication-based ileoscopy in real-life practice.

Methods: The authors reviewed endoscopic reports of patients who underwent colonoscopies over an 8-year period (2011–2018) and had routine ileoscopy during these procedures. Demographic data, indications for colonoscopy, and endoscopic findings were documented. Diagnostic yield and odds ratio for TI findings were calculated.

Results: Over 30,000 colonoscopy reports performed during the study period were reviewed. Ilesocopy was performed in 1800 patients, 216 patients had findings in the TI (ileitis or ulcers). TI findings were more prevalent in younger ages (38.3 ± 17.6 vs. 43.6 ± 20, P < 0.05). The greatest yield of ileoscopy was evident when performed for the evaluation of chronic abdominal pain and diarrhea (14.4% vs. 9.3%, odds ratio [OR] 1.62, P < 0.05). Positive fecal occult blood test (FOBT) (OR 0.1, 95% confidence interval [95%CI] 0.02–0.5, P = 0.005) and constipation (OR 0.44, 95%CI 0.2–0.9, P = 0.04) were negatively associated with TI findings.

Conclusions: Ileoscopy may have the greatest utility in evaluating suspected inflammatory bowel disease (IBD) patients, but may not add value to the evaluation of constipation and positive FOBT

Objective: To review the clinical presentation of gastrointestinal duplications and present our experience with such lesions over the past decade.

Methods: The records of all patients treated for gastrointestinal duplications at a tertiary hospital during 1987 through 1996 were collected, and relevant published literature reviewed.

Results: In the nine patients with gastrointestinal duplications, six were in the small bowel and one each in the cecum, colon and esophagus. Presenting clinical features were varied and often subtle. Perinatal ultrasonography, radioscintography and computerized tomography were useful in some cases, while in others the correct diagnosis was established only at surgery.

Conclusions: Alimentary tract duplications are uncommon, and may present as solid or cystic tumors, intussusception, perforation or gastrointestinal bleeding. A high index of suspicion is required when dealing with such cases. Appropriate investigations, including imaging techniques, should be directed toward adequate and planned surgery.
