Diagnostic analysis of capsule endoscopy in chronic abdominal pain

Objective The aim of the study is to evaluate value and safety of capsule endoscopy in diagnosing chronic abdominal pain. Methods From Sep. 2008 to July 2009,45 capsule endoscopy procedures were performed in 25 patients with chronic abdominal pain and 20 Asymptomatic controls.Diagnoses by capsule endoscopy were recorded and compared. Results Capsule endoscopies were completed successfully in 45 patients.All of the capsules eventually passed out spontaneously after procedures.All the patients did not complain of any uncomfortable feeling.The finding in chronic abdominal pain group included 3 cases of small intestinal ulcers(12%),2 cases of small intestinal polyp(8%),1 case of volvulus of duodenum(4%),1 case of jejunal phlebangioma(4%),1 case of jejunal ascarids(4%),1 cases of ileum erosion(4%).The findings in asymptomatic control group included 2 cases of small intestinal polyp(10%),1 case of ileum erosion(5%).Comparing the 2 groups,prevalence in chronic abdominal pain group was significantly higher than that in asympotomatic control(P0.01).The capsules were stayed in stomach in(40.99±31.38) min and(37.90±24.89) min,reached in ileum bottom in (220.89±91.64)min and (225.68±80.59) min,no significant difference was found between 2 groups(P0.05). Conclusion Capsule endoscopy is a safe procedure and valuable tool in diagnosing chronic abdominal pain.
