“…Salvage methods for non-operable IPMN include radiofrequency ablation (RFA) or alcohol ablation performed via ERCP or under endosonographic guidance [14,15]. Baughman et al detailed use of laser fulguration with a holmium laser fiber within a ureteroscope through a percutaneous biliary drain in a single patient with a biliary IPMN, but application of laser ablation endoscopically in the pancreatic duct under direct visualization as described in this study offers another treatment modality for IPMN [16]. While surgical resection remains the treatment of choice for main-duct IPMNs, further studies examining laser ablation are needed in non-surgical symptomatic patients.…”

Background and study aims Cholangiopancreatoscopy-guided laser dissection or ablation (CPL) is a novel therapeutic modality for refractory benign strictures. Our aim was to describe the safety and efficacy of CPL for pancreaticobiliary disorders. Patients and methods Patients who underwent CPL using holmium or thulium laser between February 2017 and September 2019 were included. For stricture dissection, gentle strokes of the laser fiber from a distal to proximal approach were applied until luminal patency permitted advancement of the cholangiopancreatoscope. Immediate technical success was defined as ability to traverse the stricture with the cholangiopancreatoscope after CPL. Short-term technical success was defined as > 90 % resolution of the stricture on follow-up pancreatogram. Results Eleven patients underwent a mean of 3.6 ERCPs (mean total diameter of 14.2 Fr of stenting) prior to CPL. Indications included pancreatic duct stricture (n = 8), pancreaticojejunostomy anastomotic stricture (n = 1), bile duct stricture (n = 1) and pancreatic intraductal papillary mucinous neoplasm ablation (n = 1). Immediate technical success was 94.1 % and short-term technical success rates was 88.2 %. At a mean follow-up of 12.1 months, there have been no stricture recurrences. Conclusions CPL may be an effective therapy for strictures refractory to conventional dilation and multiple stenting.

“…6 Cholangioscopy, including PTCS and peroral cholangioscopy, can be used to approach the bile duct directly, confirm the histology, and assess the extent of the tumor, including superficial spreading along the biliary epithelium, which provides information that can be used to choose the appropriate treatment. 7,8 In this patient, contrast-enhanced abdominal and pelvic 13 PDT showed early promise but has demonstrated a high complication rate including cholangitis due to necrosis in adjacent normal tissue and photosensitivity. 14 APC uses argon gas to deliver plasma of evenly distributed thermal energy to a field of tissue adjacent to the probe.…”

“…Recently, treatment options by choledochoscopy have been described. Baughman et al [33] reported intraductal laser resection using a choledochoscope, and biliary tract angiography showed that tumors were completely resected. Jazrawi et al [34] performed intraductal argon plasma coagulation in patients with biliary papillomatosis, and achieved a certain effect, but residual tumor was still found, and recurrence happened.…”

Biliary Papillomatosis and New Ultrasound Imaging Modalities

et al. 2012

Biliary papillomatosis (BP) is a rare disorder of the biliary tract with a significant risk of malignant transformation and a high recurrence rate after operation due to the diffuse distribution of the disease. Preoperative diagnosis is difficult also by reason of the low sensitivity and specificity of conventional ultrasound (US), computed tomography (CT), magnetic resonance imaging (MRI), endoscopic retrograde cholangiography (ERC) and positron emission tomography (PET). Therefore, the introduction of new diagnostic imaging methods is of importance to improve the preoperative diagnosis of this originally as benign described disease which is reflected in the term of "benign papillomatosis of the biliary tree". The present review summarizes the literature and discusses new sonographic imaging techniques including contrast-enhanced ultrasound (CEUS), contrast-enhanced low mechanical endoscopic ultrasound (CELMI-EUS) and endoscopic ultrasound elastography.
