Abstract

Background and study aims: Spiral enteroscopy is a new technique for deep small-bowel intubation that uses a special overtube (Discovery Small Bowel, DSB) to pleat small bowel. The aims of this prospective study were to evaluate the use of a new-design DSB over new, longer and smaller-diameter enteroscopes, the Fujinon EN-450T5 and the Olympus SIF-Q180.

Patients and methods: This is a prospective study of 75 patients at two referral centers. All enteroscopies were performed by two experienced endoscopists. Patients underwent spiral enteroscopy perorally with the DSB and either the Fujinon EN-450T5 or the Olympus SIF-Q180 enteroscope. Procedure time and depth of insertion past the ligament of Treitz were determined for all patients.

Results: Peroral spiral enteroscopy with DSB was performed in 50 patients with the Fujinon enteroscope and in 25 patients with the Olympus. Average estimated depth of insertion was 243 cm (range 50 - 380 cm) vs. 256 cm (range 50 - 400 cm) and the average time to reach this depth was 18.7 minutes (range 7 - 52 minutes) vs. 16.2 minutes (range 7 - 33 minutes) in the Fujinon and the Olympus groups respectively. Overall findings were 10 angiodysplasias, 2 small-bowel tumors, 1 Peutz-Jeghers polyp, 1 case of celiac sprue, 2 of small-bowel strongyloidiasis, and 2 small-bowel ulcers. All angiodysplasias were treated with bipolar cauterization. Biopsies were taken from the small-bowel tumors. There were no major complications.

Conclusions: The new DSB is a means of rapid, safe, and effective deep small-bowel intubation. Depth of insertion into the small bowel and total procedure time compare favorably with other deep enteroscopy techniques. The DSB performed equally well with both enteroscopes.
