Wireless capsule endoscopy in Israeli Defense Force: two years of experience

Evaluate outcome and diagnostic yield of capsule endoscopy (CE) in soldiers with suspected small bowel disease, in comparison to traditional diagnostic procedures.

27 consecutive soldiers who underwent CE between June 2002 and February 2004 were enrolled. Results of CE were compared to standard techniques.

CE was normal in 16 patients (59.3%). Findings could not explain any signs or symptoms were observed in 11.1%. Definite diagnosis of Crohn's disease was obtained in 11.1%. Patients (62.5%) with a triad of symptoms (abdominal pain, changed bowel habits, and gastrointestinal bleeding) versus 15.8% without that triad, had either diagnostic or suspicious CE (p = 0.015). Diagnostic yield of CE was higher in gastrointestinal bleeding (25%) in comparison to suspected Crohn's disease (15.8%). Three out of 6 patients (50%) with suggestive findings of Crohn's disease in the preliminary workup were diagnosed as definite Crohn's by capsule endoscopy. CE allowed the physician to conclude workup in 71% patients.

CE should be used when obscure gastrointestinal bleeding or Crohn's disease is suspected without a conclusive diagnosis. Furthermore, when a triad of symptoms exists CE should be considered as first line examination.
