Effectiveness of direct needle puncture for complete hepaticojejunostomy anastomotic stricture after pancreaticoduodenectomy (with video).

ABSTRACT: A 79-year-old Japanese woman, who had undergone pancreaticoduodenectomy 6 months prior to presentation owing to pancreatic cancer, complained of jaundice with high fever. Computed tomography revealed proximal bile duct dilatation with complete hepaticojejunostomy anastomotic stricture (HJAS). We performed a single-balloon endoscopy for biliary drainage. The presence of a scar-like feature surrounding the anastomosis was identified as the HJAS. White-light imaging during single-balloon endoscopy revealed that the HJAS contained a milky whitish area (MWA), suggesting that a membranous and fibrosis layer affected continuous inflammation around the center of the anastomosis (within a scar-like feature). Endoscopic dilatation was performed using an endoscopic injection needle, with the MWA used
