Prospective multicenter trial comparing push-and-pull enteroscopy with the single- and double-balloon techniques in patients with small-bowel disorders.

Objectives: Double-balloon enteroscopy (DBE) is now an established method for diagnostic and therapeutic small-bowel endoscopy. Single-balloon enteroscopy (SBE) has been introduced to simplify the technique. A prospective randomized study was carried out to compare the two methods.

Optical coherence tomography and confocal scanning laser tomography for assessment of macular edema.

Purpose: To compare optical coherence tomography (OCT) and confocal scanning laser tomography (cSLT) for quantitative retinal thickness mapping of the macula and their ability to detect macular edema.

Design: Prospective, comparative, clinical observational study.

Methods: The study population of 138 eyes (97 patients) was divided into a study group consisting of 45 (32.
