Overtube-Assisted ERCP in Patients with Surgically Altered Anatomy: A Single Center One-Year Experience

Prospective evaluation of spiral overtube–assisted ERCP in patients with surgically altered anatomy

“…Spiral overtube-assisted ERCP has previously been reported only as small retrospective case series in abstract form. Hegde et al 15 reported their experience with overtube-assisted ERCP in 13 patients (3 with the spiral overtube). Overall, successful cannulation was performed in 57% and in all 3 cases with the spiral overtube (including 2 cases wherein double-balloon enteroscopy had failed).…”

“…[11][12][13][14] To date, spiral overtube-assisted ERCP has been described in only a few patients as retrospective reviews in abstract form. 15,16 We therefore performed a prospective evaluation to assess the use of the spiral overtube in performing ERCP in patients with surgically altered anatomy.…”

Spiral Assisted ERCP Is Equivalent to Single Balloon Assisted ERCP in Patients with Roux-en-Y Anatomy

“…There are several case reports and abstracts of SBE-ERCP, the majority of which consist of small numbers of patients (1-13) with only one large series of 50 patients [4][5][6][7][8][9][10][11][12][13]. The diagnostic yield in these studies varies from 53.8 to 100%.…”

Single-balloon enteroscopy effectively enables diagnostic and therapeutic retrograde cholangiography in patients with surgically altered anatomy

“…In recent years, deep intubation of the afferent biliary limb has been achieved by using a ShapeLock overtube, 12 spiral or rotational enteroscopy, 13 and double-balloon enteroscopy (DBE). [14][15][16][17][18] However, data on the use of spiral enteroscopy and the ShapeLock overtube are limited, whereas DBE requires specialized equipment and expertise that are not widely available.…”
