Endoscopic papillary large balloon dilation with a novel non-slip balloon in a patient with surgically altered anatomy

Endoscopic papillary large balloon dilation (EPLBD) in balloon enteroscopy-assisted endoscopic retrograde cholangiopancreatography (BE-ERCP) is an effective procedure for stone removal [1] [2]. However, balloon slipping often occurs when an enteroscope is unstable. A novel balloon catheter (RIGEL Balloon Dilation Catheter; Japan Lifeline Co., Ltd., Tokyo, Japan) forms a waist because of the central band, which can prevent slipping during dilation ([Fig. 1]) [3] [4]. Herein, we report a case of a patient with surgically altered anatomy who underwent EPLBD with a 12-mm RIGEL balloon ([Video 1]).

A 60-year-old male who had undergone distal gastrectomy with Roux-en-Y reconstruction was referred to our hospital for choledocholithiasis. BE-ERCP was performed to remove common bile duct stones ([Fig. 2]). A short-type single-balloon enteroscope (SIF-H290S; Olympus Medical Systems, Tokyo, Japan) was inserted, and the papilla of Vater was detected in the third part of the duodenum. A rotatable papillotome was used for biliary cannulation; however, alignment for biliary access was difficult. The double-guidewire technique was used because the enteroscope was unstable. Eventually, selective biliary cannulation was achieved. Cholangiography revealed gallstones and a dilated distal bile duct. The EPLBD was attempted to facilitate recanalization and stone removal ([Fig. 3]). A RIGEL 12-mm balloon was inserted along the guidewire smoothly, and a black marker at the middle part of the balloon was adjusted at the orifice of the bile duct. Subsequently, the balloon was gradually inflated, and delayed dilation of the middle part prevented balloon slippage. The balloon was dilated up to the diameter of the bile duct. Finally, a biliary stent was placed because the procedure took a long time. The patient was discharged without complications and stone removal was scheduled for a later date.

To the best of our knowledge, this is the first report of an EPLBD using a novel 12-mm RIGEL balloon. The unique structure of the RIGEL balloon was effective for EPLBD without slippage, even when enteroscope positioning was unstable.
