Double balloon endoscopy in diagnosis of ulcerative lesions in small intestine / 中华消化内镜杂志

ABSTRACT

Objective To evaluate the use of double balloon endoscopy(DBE) in diagnosis of ulcerative lesions in small intestine.Methods Data of patients diagnosed as small intestinal ulcer under DBE during September 2003 and December 2007 at Nanfang Hospital were analyzed retrospectively.Results Ulcer in small intestine was detected by DBE in a total of 62 patients,including 48 males and 14 females,aging from 10 to 71 years old( mean 43.9 yr).The main clinical manifestations consisted of small intestinal hemorrhage(38/62,61.3%),abdominal pain(16/62,25.8%),abdominal distention(5/62,8.1%),loss of weight(2/62,3.2%),and diarrhea(1/62,1.6%).The ulcers were diagnosed endoscopically as Crohn's disease(CD) in 53 cases(85.5%),drug induced lesions in 4(6.5%),nonspecific chronic inflammation in 2(3.2%),lymphoma in 2(3.2%) and tuberculosis in 1(1.6%).They were all microscopically diagnosed as chronic inflammation.Of the 62 patients,32(51.6%) underwent surgery.In 30 cases of CD diagnosed by DBE,22 were confirmed by post-surgery pathology(malignant cells were found in 3),while in the other 8 cases,4 were diagnosed as lymphoma,3 as Behcet's disease and 1 as tuberculosis.Meanwhile,the 1 case of tuberculosis and 1 lymphoma diagnosed by DBE were confirmed as CD after operation.The overall accurate diagnosis rate of small intestinal ulcerative lesions by DBE was 68.8%(22/32).Conclusion DBE is valuable in diagnosis of ulcerative lesions in small intestine,but surgery should be included into consideration to confirm the diagnosis when necessary.
