Safety and efficacy of single balloon enteroscopy for small intestinal disorders / 中华消化内镜杂志

ABSTRACT

Objective To evaluate safety and clinical significance of single balloon enteroscopy (SBE) for small intestinal diseases. Methods Data of 83 patients with suspected or known small intestinal diseases, who underwent SBE from March 2009 to July 2010, were reviewed in terms of preparation time,procedure time, detection rate and complication occurrence. Results The 83 patients included 37 cases of digestive tract bleeding, 38 chronic abdominal pain, 1 chronic diarrhea, 2 fever and 5 incomplete ileus. A total of 94 procedures of SBE were performed, including oral route in 46 patients, anal route in 26 and both routes in 11. Excluding 6 cases with endoscopic therapy, the mean procedure time of oral approach was 29.6 ± 10. 3 min, and that of anal route was 57.1 ± 15.6 min. Abnormalities were detected in 57 ( 68.7% )of the 83 patients, with detection rate of 81.1% (30/37) in digestive tract bleeding with unknown reason,57. 8% (22/38) in chronic abdominal pain of unknown reason, 50. 0% (1/2) in fever of unknown reason and 80. 0% (4/5) in incomplete ileus. Peutz-Jeghers syndrome was diagnosed in 6 patients and endoscopic polypectomy was performed, with complicated bleeding in one patient. No other procedure-related complications were observed. Conclusion SBE is well-tolerated and safe for diagnosis of small intestine diseases,with easy manipulatiou, short procedure time, high detection rate and satisfactory location of intestinal hemorrhagic lesions.
