The Comparison Of Application Of Double Balloon Endoscopy And Capsule Endoscopy In Small Intestinal Bleeding

Objective To compare the diagnostic power, the etiological diagnostic accuracy, patient's tolerance and safety of double balloon enteroscopy and capsule endoscopy in patients with small intestine bleeding.To explore the endoscopic therapy of double balloon enteroscopy for small intestine bleeding.Methods In 159 patients with small intestine bleeding in Department of Gastroenterology of Yantai Yuhuangding Hospital from April,2006 to October,2009, double balloon enteroscopy was performed 81 patients.The route of enteroscopy could be underwent either via mouth or via anus. If the result was negative in initial route, another examination was required either via mouth or via anus. For active small intestinal bleeding detected during examination, endoscopic hemostasis was done. Capsule endoscopy was performed in 78 patients.The results of both methods were analyzed independently and final diagnosis of each case was compared thereafter to compare clinical value of double balloon enteroscopy and capsule endoscopy.Results The overall diagnostic rate for double balloon enteroscopy was 95.06%(77/81), and the etiological diagnostic accuracy was 82.72%(67/81).Active bleedings were detected in 23 cases, endoscopic hemostasis was successfully made in 21 cases (91.30%). The overall diagnostic rate for capsule enteroscopy was 82.05%(64/78), and the etiological diagnostic accuracy was 66.67%(52/78). Double balloon enteroscopy was superior to capsule endoscopy in the diagnostic power and the etiological diagnosis of small intestinal bleeding (P<0.05). patient's tolerance was better for capsule endoscopy than for double balloon enteroscopy. Toleration of double balloon enteroscopy was in turn under anaesthesia via anus, under anaesthesia via mouth, via anus without anaesthesia and via mouth without anaesthesia. No serious complications occurred in all patients.Conclusions Double balloon enteroscopy is superior to in the diagnosis of small intestinal bleeding and endoscopic hemostasis could be done to treat bleeding by it. Double balloon enteroscopy could be served as one safe and effective method in diagnosis and therapy of obscure small bowel bleeding.
