For patients with surgically altered gastrointestinal anatomy, the difficulty of performing endoscopic retrograde cholangiopancreatography (ERCP) has been reported 1 2 3 . After proximal gastrectomy, double tract reconstruction is usually performed (PG-DT), and some patients with PG-DT require ERCP. Although a technique of guidewire-assisted side-viewing scope insertion for patients with PG-DT has been reported 4 , the bent and tortuous nature of the interstitial jejunum and the end-to-side anastomosis of the gastric jejunum make it difficult ( Fig. 1 ).

A large-diameter sliding tube (ST-CB1; Olympus, Tokyo, Japan), which was designed for colonoscopy, has a length of 770 mm, and outer and inner diameters of 16.2 mm and 13.8 mm, respectively ( Fig. 2 ) 5 .

A large-diameter sliding tube (ST-CB1; Olympus, Tokyo, Japan), which was designed for colonoscopy, has a length of 770 mm, and outer and inner diameters of 16.2 mm and 13.8 mm, respectively.
Herein, we report a case of sliding tube-assisted ERCP using this single-use sliding tube in a patient with PG-DT.
A 63-year-old man who underwent PG-DT was admitted for treatment of cholelithiasis, for which ERCP was performed. First, guidewire-assisted side-viewing scope insertion was attempted, but the scope was unable to cross the gastrojejunal anastomosis owing to the flexion and meandering of the anastomosis. Therefore, we used a large-diameter sliding tube to secure the side-viewing scope insertion route. An upper endoscope was inserted into the gastric antrum beyond the gastrojejunal anastomosis, with a sliding tube attached to the scope; the scope was then removed, leaving the sliding tube in place ( Fig. 3 ).

An upper endoscope was inserted into the gastric antrum beyond the gastrojejunal anastomosis, with a sliding tube attached to the scope; the scope was then removed, leaving the sliding tube in place.
The sliding tube straightened the curvature of the gastrojejunostomy lumen, and the side-viewing scope was successfully passed through the lumen of the tube to the duodenum; the scope stretch was also successful ( Fig. 4 ). Subsequently, removal of the stone in the common bile duct was successful ( Fig. 5 , Video 1 ). Adverse events, such as damage to the anastomotic site during insertion of the sliding tube, did not occur in this case.

Video 1 Single-use sliding tube developed to improve colonoscopy operability for side-viewing scope insertion in a patient who had undergone proximal gastrectomy followed by double tract reconstruction.
This sliding tube-assisted side-viewing scope insertion technique is considered effective for patients with PG-DT anatomy.
