Endoscopic transpapillary gallbladder drainage (ETGBD) is effective for patients in
whom cholecystectomy or percutaneous transhepatic gallbladder drainage (PTGBD) is
contraindicated [1]
[2]. However, in some patients, the guidewire cannot be advanced into the cystic duct
because of the caudal distribution of the cystic duct. Herein, we present a case in
which use of the balloon occlusion method enabled guidewire insertion into a cystic
duct with caudal distribution, thus allowing ETGBD to be successfully performed.
An 82-year-old woman with right upper quadrant pain and high fever was admitted to
our hospital and diagnosed with acute cholecystitis and Chilaiditi syndrome based
on CT findings ([Fig. 1]). In view of the high surgical risk and contraindication of PTGBD because of the
Chilaiditi syndrome, the patient underwent ETGBD. After bile duct cannulation, the
cystic duct could not be visualized by cholangiography via the cannula, and guidewire
insertion into the cystic duct was impossible. Hence, we inflated an occlusion balloon
below the bifurcation of the hilar bile duct and injected a contrast agent via the
proximal port of the balloon catheter; this allowed detection of the cystic duct ([Fig. 2]). However, the guidewire could not be advanced into the cystic duct because of the
caudal distribution of the duct. Therefore, we inflated the occlusion balloon right
above the origin of the cystic duct takeoff. Using a two-devices-in-one-channel method
[3], we inserted a hydrophilic guidewire (Radifocus; Terumo Co. Ltd., Tokyo, Japan)
into the bile duct ([Fig. 3a]). Then, the guidewire was inverted in the bile duct by the inflated balloon, thereby
successfully advancing into the cystic duct ([Fig. 3b]). After the hydrophilic guidewire was inserted into the gallbladder ([Fig. 4a]), it was changed to a stiff type. Finally, we placed a spiral-shaped plastic stent
[4], positioning the tip at the gallbladder fundus ([Fig. 4b]).

This case shows that the balloon occlusion method can be useful to successfully perform
ETGBD, particularly in patients with caudal distribution of the cystic duct ([Video 1]).
