Improved techniques for double-balloon-enteroscopy-assisted endoscopic retrograde cholangiopancreatography

Abstract

Short-type DBE combined with several technical innovations enabled us to perform ERCP in most patients with altered gastrointestinal anatomy.

Diagnostic and Therapeutic Endoscopic Retrograde Cholangiography Using a Short-Type Double-Balloon Endoscope in Patients With Altered Gastrointestinal Anatomy: A Multicenter Prospective Study in Japan

“…Most of the endoscopes used in the study by Shah et al ( 37 ) study were either standardtype DBEs or standard-type single-balloon endoscopes, whereas we used only a short-type DBE. Previous studies of ERCs using only a short-type DBE have reported success rates of reaching the target site of 86-100%, success rates of ERC-related interventions of 90-96%, and overall success rates of 81-94% (38)(39)(40). Th ese rates are consistent with the rates in our present study and suggest that the use of a short-type DBE contributes to an improved procedural success rate.…”

“…Roux Th e time required to complete the DB-ERC procedure was comparable to or slightly shorter than previously reported times ( 36,40,41 ).…”

“…Th e incidence of DB-ERC-related adverse events has been reported to be 0-17% (30)(31)(32)(33)(34)(35)(36)(37)(38)(39)(40)(41), but most relevant reports are based on small numbers of patients, and no solid data have been reported. In a study conducted by Shah et al ( 37 ), adverse events occurred in 12% of patients and included pancreatitis ( n =5; 4 mild and 1 severe cases), mild bleeding ( n =1), abdominal pain requiring hospital admission ( n =3), throat pain requiring physician contact ( n =4) and perforations ( n =2).…”

“…Osoegawara et al ( 40 ) reported the duration to reach the blind end was 30.5±3.7 min and the total duration of the procedure was 93.6±6.8 min Cho et al ( 41 ) reported the duration to reach the blind end was 20.8 min(range; 5-82 min), the total duration of the procedure was 70.7 min(range; 30-117 min) In our study, the time required to reach the blind end was 22.4±20.8 min (range; 2-114 min) and the total duration of the procedure was 78.5±38.1 min (range; 9-209 min), which were almost equivalent to or slightly shorter than durations from previously published papers. Th e duration time varied in a wide range, which suggested diffi cult cases required longer time to complete the procedures.…”

ERCP using a short double-balloon enteroscope in patients with prior pancreatoduodenectomy: higher maneuverability supplied by the efferent-limb route

“…surgically altered anatomies has been facilitated by the development of balloon enteroscopy, including the use of a double-balloon enteroscope (DBE), a single-balloon enteroscope, and a short DBE [2][3][4][5], and ERCP has been commonly performed as the initial attempt to manage postoperative disorders prior to percutaneous drainage and reoperation.…”
