ERCP Sampling for Biliary Stricture Evaluation

Check if the same lab product or an alternative is used in the 5 most similar protocols

ERCP was performed by two experienced endoscopists using standard duodenoscopes (TJF-Q 180V or TJF-Q190V, Olympus, Hamburg, Germany) with patients under conscious sedation or general anesthesia. In all naive cases, biliary sphincterotomy was performed. Measures for the prevention of post-ERCP pancreatitis (PEP) and cholangitis were employed in accordance with available guidelines.
During ERCP, each biliary stricture was sampled twice using the cytology brush (BrushMaster V, Olympus, Hamburg, Germany) inserted over a guidewire, with at least 10 to-and-fro motions through the stricture per sampling under fluoroscopy control. Dilatation of the stricture was not routinely performed. Material from the first sampling was smeared directly onto microscopic slides for routine cytology. After the second sampling, the brush was cut and placed into 10 mL of ThinPrep CytoLyt solution (Hologic, Marlborough, MA, USA) for subsequent FISH analysis. The sampling was considered successful when the tissue sample obtained was of sufficient quantity and quality to enable both cytological and FISH analysis. Routinely, biliary plastic or fully covered self-expandable metallic stents were introduced.

Patients were prepared with a 6-hour fast and administration of 10 mL simeticone solution. Esophagogastroduodenoscopies (EGD) were performed under conscious sedation with fentanyl, midazolam, and propofol administered by a second physician. All patients were evaluated with lateral (Olympus, TJF-Q180V) and forward view (Olympus, GIF-H180) EGD. Endoscopic features, number, size, anatomic location, and Paris classification were reported for every case. Duodenal polyposis was classified according to the Spigelman staging system and ampullary adenomas were also identified. A minimum of four biopsies were taken from larger duodenal polyps and two biopsies from suspicious ampullary lesions. All histopathologic specimens were reviewed by an experienced pathologist with expertise in gastrointestinal tract evaluation. Additionally, when endoscopic mucosectomies were performed, the resected specimens were used to complement the Spigelman staging of duodenal adenomatosis. Patients with advanced duodenal polyposis (Spigelman III or IV) underwent antegrade balloon assisted endoscopy (BAE) (Fuji, EN-450T5 or Fuji, EN-580 T) for jejunal examination approximately 1 month after initial EGD. All gastroduodenoscopies and BAEs were performed by two experienced endoscopists (M. S. and A. S. R).

We conducted a prospective nationwide cross-sectional study among all Dutch ERCP centres. In the Netherlands, over 16.000 ERCP procedures are performed in 73 ERCP centres yearly.19 (link) All 73 Dutch ERCP centres were asked to sample at least two duodenoscopes at their own choosing and, if present, to include the newest Olympus TJF-Q180V (Olympus, Zoeterwoude, The Netherlands). Duodenoscopes were eligible for sampling if they were reprocessed and ready for patient use, for example, after high level disinfection or after drying in the storage cabinet. No data were recorded about the moment of sampling, surveillance methods or adherence to reprocessing or sampling protocols. No patient data were included in this study; therefore, there was no need for approval by the Medical Ethical Research Committee.

Duodenoscope Contamination Rates Comparison

Check if the same lab product or an alternative is used in the 5 most similar protocols

Categorical data are presented in percentages. Mean (range) and median (IQR) are given for continuous and skewed data, respectively. The χ² test was used to compare categorical data and Student’s t-test or Mann Whitney U-test was used to compare continuous data. Contamination rates of duodenoscope types and sample sites were compared according to a logistic regression model, using the SAS procedure GENMOD. This model adjusted for the multiple samples of each unique duodenoscope, with each duodenoscope clustered within their respective ERCP centre. Duodenoscope types were compared with the newest Olympus TJF-Q180V type as a reference and sample sites were compared with the flush of the biopsy channel. For both analyses, duodenoscope types or sample sites could be included if there was at least one contamination case and one non-contamination case. Analyses were performed using SAS V.9.4 (SAS, Cary, North Carolina, USA) and SPSS V.21.0 (IBM, Armonk, New York, USA).

EUS-Guided Small Intestine Access

Check if the same lab product or an alternative is used in the 5 most similar protocols

Following EUS, in cases where wire access into the small intestine was achieved, a duodenoscope (TJF-160VF, TJF-Q180V; Olympus) or pediatric colonoscope (PCF-H180AL, PCF-Q180AL; Olympus) was maneuvered into the small intestine and the wire visualized. In most cases, a snare or foreign body grasper was then utilized to grip the wire and pull it back through the scope. Cannulation of the PD over or next to the wire was then performed. Additional therapy consisted of dilation, extraction of stones/debris, and placement of plastic stents into the PD. In select patients for whom wire access was not achieved, conventional ERCP techniques were re-attempted with limited success.

Endoscopic treatment: ERC was carried out using a therapeutic duodenoscope (TJF160R, TJF160VR, TJFQ180V, Olympus Corp., Tokyo, Japan). Selective cannulation of the common bile duct was performed with a guide wire (Jagwire, 0.035 inch, Boston Scientific, Natick, MA, USA, Visiglide, 0.035 inch, Olympus Corp., Tokyo, Japan) or a standard catheter for cases with pre-existing sphincterotomy. All procedures were performed under conscious sedation with propofol and short-acting opiates. All patients received peri-interventional antibiotic prophylaxis.
After visualization of the biliary stricture balloon dilation was performed with 18-Fr balloons at the initial intervention and 24-Fr balloons at subsequent interventions if the stricture was distal to the hilum. If indicated 10 Fr plastic stents (Endoplus Drainage, Pflugbeil, Germany) in appropriate length and number were inserted to bridge strictures.

Endoscopic Retrograde Cholangiopancreatography (ERCP) Technique

Check if the same lab product or an alternative is used in the 5 most similar protocols

Two endoscopists with ≥ 10 years of experience, who performed annually more than 300 ERCPs annually, performed all ERCP procedures at UMMC as the operator or supervisor. A side-viewing duodenoscope (TJF-Q180V; Olympus Medical Systems, Tokyo, Japan) was inserted into the second part of the duodenum, and the papilla of Vater was visualized in the en face view. Cannulation of the bile duct was performed using an ST-papillotome (Clever Cut 3V: KD-V411M-0730; Olympus Medical Systems, Tokyo, Japan) or the OT-papillotome. After minimal insertion (1-3 mm) of the papillotome across the papilla, a 0.025-inch guide wire was advanced under fluoroscopic guidance. If the guide wire was fluoroscopically confirmed to have entered the bile duct, the papillotome was advanced deeply into the duct. If the guide wire was accidentally inserted into the pancreatic duct, it was immediately withdrawn from the duct and biliary cannulation was attempted again. If the operator was unable to accomplish deep cannulation of the bile duct after 10 minutes, the papilla precut technique and/or pancreatic duct guide wire technique was used for cannulation. After deep biliary cannulation was achieved, EST, endoscopic lithectomy, or EBD was performed as required.

Check if the same lab product or an alternative is used in the 5 most similar protocols

ERC was performed using either duodenoscopes or orthograde endoscopes. The duodenoscopes used in this trial belong to the 180er series of Olympus (TJF-Q180V; Japan). Selective cannulation of the common bile duct was indicated in all cases. Operator-dependent wire-guided cannulation with sphincterotome (e.g., double lumen sphincterotomes; Boston Scientific, Marlborough, MA, USA) or catheter (Wieser, Germany) were used in native papillae. Pretreated papillae were cannulated with balloon catheter (Olympus, Tokyo, Japan) or standard catheter with or without wire depending on operator's choice. The bile aspirates analysed in this trial were completely obtained before contrast enhancement.
ERC was performed under conscious sedation as a standard procedure using midazolam, propofol, and/or opioids according to the German guidelines [16] . The guidelines of the German Society of Digestive and Metabolic Diseases (DGVS) recommend a prophylactic antibiotic therapy prior to ERC under certain conditions [17] .
