An 89-year-old man was referred to our hospital for treatment of hepatolithiasis causing recurrent cholangitis. He had undergone a priorWhipple procedure. Computed tomography demonstrated left-sided hepatolithiasis. First, we conducted peroral direct cholangioscopy(PDCS) using an ultraslim endoscope. Although PDCS was successfully conducted, it was unsuccessful in removing all the stones. Thestones located in the B2 segment were diffcult to remove because the endoscope could not be inserted deeply into this segment due to thesmall size of the intrahepatic bile duct. Next, we substituted the endoscope with an upper gastrointestinal endoscope. After positioningthe endoscope, the SpyGlass digital system (SPY-DS) was successfully inserted deep into the B2 segment. Upon visualizing the residualstones, we conducted SPY-DS-guided electrohydraulic lithotripsy. The stones were disintegrated and completely removed. In cases ofPDCS failure, a treatment strategy using the SPY-DS can be considered for patients with hepatolithiasis after a Whipple procedure.

Background/Aims: Intralesional steroid injections have been administered as prophylaxis for stenosis after esophageal endoscopicsubmucosal dissection. However, this method carries a risk of potential complications such as perforation because a fine needle is usedto directly puncture the postoperative ulcer. We devised a new method of steroid intralesional infusion using a spray tube and evaluatedits efficacy and safety. Methods: Intralesional steroid infusion using a spray tube was performed on 27 patients who underwent endoscopic submucosal dissectionfor superficial esophageal cancer with three-quarters or more of the lumen circumference resected. The presence or absence ofstenosis, complications, and the number of endoscopic balloon dilations (EBDs) performed were evaluated after treatment. Results: Although stenosis was not observed in 22 of the 27 patients, five patients had stenosis and dysphagia requiring EBD. The stenosisin these five patients was relieved after four EBDs. No complications related to intralesional steroid infusion using the spray tubewere observed. Conclusions: Intralesional steroid infusion using a spray tube is a simple and safe technique that is adequately effective in preventingstenosis (clinical trial number, UMIN000037567).
