Prophylactic pancreatic duct (PD) stent placement is an effective measure to reduce its incidence [1] . However, conventional PD stents require follow-up X-rays for the confirmation of spontaneous dislodgement or a second endoscopy for removal, which imposes additional patient discomfort and financial burden [2] . We designed a novel method that allows for the simultaneous removal of a PD stent along with a nasobiliary catheter (NBC) at the bedside, based on clinical needs.  \nA 36-year-old woman presented with abdominal pain. Magnetic resonance cholangiopancreatography confirmed choledocholithiasis, and she was scheduled for ERCP ( ▶Video 1) . Pre-procedure preparation: The NBC and PD stent were pre-modified by tying a surgical suture at their marked positions, forming a loop of approximately 1.5cm in diameter ( ▶ Fig. 1a, b) . During the ERCP procedure, the guidewire was first advanced into the  \n▶Fig. 1 An innovative method: a pancreatic duct stent for removal alongside the nasobiliary catheter. a The surgical suture tied at the marked site of the nasobiliary catheter, and the suture loop diameter is 1 .5cm. b The surgical suture tied at the marked site of the pancreatic duct stent, and the suture loop diameter is 1.5cm. c Placement of the pancreatic duct stent with the tied suture. d Placement of the nasobiliary catheter with the tied suture. e Titanium clips used to connect the nasobiliary catheter and pancreatic duct stent. f The nasobiliary catheter and pancreatic duct stent connection device.  \npancreatic duct and was subsequently retained.  \nUsing the double-guidewire technique, the bile duct was successfully cannulated ( ▶Video 1) . The modified PD stent was deployed over the pancreatic guidewire ( ▶ Fig.1c) . Following balloon extraction of the common bile duct stones ( ▶Video 1), the modified NBC was placed ( ▶ Fig.1d) . A titanium clip was used to securely link the suture loops of the NBC and the PD stent ( ▶ Fig.1e) . At 48 hours post-procedure, the patient recovered well with no complications such as PEP, bleeding, or infection. The connected NBC-PD stent assembly was removed gently and completely at the bedside ( ▶Video 1 , ▶ Fig.1f) .  \nThis connected NBC-PD stent assembly offers dual benefits: it secures the PDstent to prevent premature migration  \nand enables its convenient, simultaneous removal with the NBC. This technique effectively obviates the need for additional imaging studies or a repeat endoscopy, presenting a representing and clinically advantageous approach worthy of broader adoption.  \nEndoscopy_UCTN_Code_TTT_ 1AR_ 2AZ  \nContributors ʼ Statement  \nHaiyong Long: Conceptualization, Data curation, Writing – original draft.
