Endoscopic retrograde cholangiopancreatography (ERCP) and associated procedures are difficult to perform in patients with surgically altered anatomy. Recently, balloon enteroscopy (BE) has made it easier to perform ERCP in these patients. However, BE-assisted ERCP is often technically demanding and time consuming.
Spiral enteroscopy (SE), which has recently been developed, is a novel method of using a rotating overtube to pleat small bowel onto the enteroscope, thus advancing it through the lumen. We review the mechanism and efficacy of SE, especially in ERCP of patients with surgically altered anatomy, and report on the first patient to undergo ERCP using SE in Japan.
Spiral enteroscopy-assisted ERCP seems to be feasible and safe in patients with surgically altered anatomy. Additionally, SE-assisted ERCP appears to be easier to perform than other methods previously described and allows stable positioning of the enteroscope in order to perform delicate therapeutic maneuvers.
SE for ERCP is expected to be at least as useful as balloon enteroscopy in patients with surgically altered anatomy.

Endoscopic retrograde cholangiopancreatography (ERCP) in patients with surgically altered anatomy involves challenging procedures for ERCP endoscopists. In these patients, the anatomical structure of ...
ERCP is a difficult procedure to perform in Billroth II gastrectomy patients due to altered anatomy. We investigated the outcomes and risk factors for adverse events for ERCP using a cap-fitted forwar...
Angiodysplasia of the gastrointestinal (GI) tract consists of ectasia of the submucosal vessels of the bowel. The evaluation of such patients needs proctoscopy, colonoscopy, small bowel enema, enteros...

Organs or parts of organs surgically formed from nearby tissue to function as substitutes for diseased or surgically removed tissue.
A spiral thickening of the fibrous lining of the cochlear wall. Spiral ligament secures the membranous COCHLEAR DUCT to the bony spiral canal of the COCHLEA. Its spiral ligament fibrocytes function in conjunction with the STRIA VASCULARIS to mediate cochlear ion homeostasis.
A spiral bacterium active as a human gastric pathogen. It is a gram-negative, urease-positive, curved or slightly spiral organism initially isolated in 1982 from patients with lesions of gastritis or peptic ulcers in Western Australia. Helicobacter pylori was originally classified in the genus CAMPYLOBACTER, but RNA sequencing, cellular fatty acid profiles, growth patterns, and other taxonomic characteristics indicate that the micro-organism should be included in the genus HELICOBACTER. It has been officially transferred to Helicobacter gen. nov. (see Int J Syst Bacteriol 1989 Oct;39(4):297-405).
The bony plate which extends outwards from the modiolus into the spiral canal of the cochlea, forming part of the structure that divides the upper SCALA VESTIBULI and the lower SCALA TYMPANI.
Modality of computed tomography in which the patient is irradiated in a spiral path around the body with a cone or pyramid-shaped beam.
