Patients and methods
Between June 29 and December 3 of 1999 the new method of enteroscopy was attempted in 4 patients. Full and informed consent was obtained from each patient before the procedure.
Results
Four patients underwent the double-balloon method of enteroscopy (Table 1).Patient Age (y) Gender Indication Sedation Scope Depth of insertion Findings Complications 1 41 M GI bleeding None XP-240 30 cm beyond LT Bleeding hemangioma None 2 14 F GI bleeding Diazepam 7.5 mg i.v. XP-240 30 cm beyond LT Bleeding hemangioma 3 78 F Protein losing enteropathy Diazepam 5 mg i.v. XP-240 40 cm beyond LT Benign stricture None 4 69 F GI bleeding Diazepam 15 mg i.v. SIF-Q240 Up to cecum Meckel's diverticulum
Discussion
The value of endoscopic exploration of the small bowel has been well documented. Established indications for small-bowel enteroscopy include unexplained digestive bleeding, radiographic abnormalities of the small intestine, and chronic diarrhea or malabsorption.1, 2, 10
At present, the most effective procedure for complete visualization of the small intestine is intraoperative enteroscopy. Fiberoptic endoscopes were used intraoperatively in the 1970s.4 No major advancements regarding insertion
