IntroductionDuodenoscopes have been widely used for both diagnostic and therapeutic endoscopic retrograde cholangiopancreatography procedures. Numerous outbreaks of duodenoscope-associated infections involving multidrug-resistant bacteria have recently been reported. Plasma activated water (PAW) has been widely considered an effective agent for surface decontamination and is increasingly used for disinfection of medical equipment. The aim of this study was to evaluate whether the duodenoscopes currently on market are suited for the repeated use of PAW and to test the efficacy of PAW for their disinfection.Materials and methodsIn order to evaluate the disinfection efficacy and the required time of contact, the duodenoscope samples were contaminated by immersing them in fasted-state simulated intestinal fluid containing Escherichia coli, Klebsiella pneumoniae, Acinetobacter baumannii, and Pseudomonas aeruginosa, prior to PAW exposure. In order to test the duodenoscope polymer compatibility with PAW, a challenge test was conducted by immersing the samples in PAW for 30 minutes daily for 45 consecutive days.ResultsSignificant reductions in bacterial populations were achieved after 30 minutes of PAW treatment, indicating a high-level disinfection. Atomic force microscopy and scanning electron microscopy were used to demonstrate that repeated PAW treatment of duodenoscope coating polymer samples did not result in significant differences in morphological surface between the treated and untreated samples. Energy-dispersive X-ray spectroscopy analysis also showed no significant differences between the elemental composition of the duodenoscope coating polymer samples before and after repeated PAW treatment.ConclusionConsidering these preliminary results, PAW could be considered as a new alternative for duodenoscope reprocessing.
The novel COVID-19 infection has spread all over the world and is still generating a lot of issues at different levels. There is a lack of control in disease early diagnosis and rapid evolution, which impacts both the medical and the economic system. Young gastroenterologists should adapt to overcome current difficulties and continue their life and general training. This is a multi-center national study, which aims to assess the general perspective of young gastroenterologists (residents and young specialists) from six university centers in Romania regarding their current training and the psychological effect the pandemic has on their life and job. An online survey with 58 items was distributed using Google Forms, and quality of life and anxiety were assessed. The validated instruments 15D (for assessing the health-related quality of life) and endler multidimensional anxiety scales (EMAS—for assessing anxiety) were used. All analyses were performed using SPSS 25. Of the 174 gastroenterologists approached, 96 (response rate of 55%) responded. A majority of the respondents were residents in gastroenterology (64%), and 40.6% were male. The pandemic influenced the number of examined patients as well as young gastroenterologists’ endoscopy training. Health-related quality of life was negatively associated with the level of anxiety generated by the cognitive component of anxiety as a state, the new and ambiguity of the state, and how threatened the respondent felt. The level of anxiety was moderate (median = 51), and no difference was found between the physicians working in a designated hospital or not. General caution should be considered for young gastroenterologists’ training, and continuous observation should be done to ensure better mental health on the current evolution. These findings would need to be verified in larger-sample studies and in different types of specialties.
Background: Endoscopic retrograde cholangiopancreatography (ERCP) has been one of the most intensely studied endoscopic procedures due to its overall high complication rates when compared to other digestive endoscopy procedures. The safety and outcome of such procedures have been linked to multiple procedure- or patient-related risk factors. The aim of our study is to evaluate whether the morphology of the major duodenal papilla influences the ERCP outcomes and complication rates. Methods: A total of 322 patients with a native papilla have been included in the study over an eight month period. Morphology of the papilla has been classified into normal papilla and four anatomical variations (Type I-IV). All patients have been prospectively monitored over a 15 day period after ERCP. Procedural outcomes and complication rates have been registered. Results: Morphology of the papilla influences both overall complication rates (95%CI, p = 0.0066) and post-ERCP pancreatitis rates (95%CI, p = 0.01001) in univariate analysis. Type IV papillae have proven to be independent risk factors for post-ERCP pancreatitis in multivariate analysis (OR = 12.176, 95%CI, p = 0.005). Type I papillae have been significantly linked to difficult cannulation (AUC = 0.591, 95%CI, p = 0.008); Conclusions: In the monitored cohort morphology of the major duodenal papilla has significantly influenced both ERCP outcomes and post-procedural complication rates.
Introduction Pancreatic malignancies represent highly fatal diseases with poor prognosis and constantly increasing incidence despite modern diagnostic and therapeutic options. Both endoscopic ultrasound (EUS) and endoscopic retrograde cholangiopancreatography (ERCP) are regarded as mainstays in pancreatic cancer management. The present study aims to evaluate whether accuracy EUS with fine‐needle aspiration or biopsy (FNA or FNB) in pancreatic cancer diagnosis is influenced by prior biliary stenting or by technical or anatomical features (stent type, number of needle passes, common bile duct or Wirsung's diameter, topographical characteristics and diameter of the pancreatic tumor). Materials and methods This retrospective study includes 243 patients with pancreatic cancer who underwent ERCP and EUS with fine‐needle aspiration or biopsy (FNA or FNB). Results and discussion Out of the total number of patients, 68 were stented prior to EUS. We found that the EUS‐FNA diagnostic yield is not influenced either by the presence of biliary stent, nor by the type of stent (plastic or metallic). Moreover, the mean needle passes required were similar for both stented patients and not stented ones. Conclusions Ultimately, given our results, we can state that EUS‐FNA/FNB can be safely and accurately performed in the presence of biliary stents.
Objectives: Duodenoscopes have been widely used for both diagnostic and therapeutic endoscopic retrograde cholangiopancreatography (ERCP) procedures, but recently, numerous outbreaks of multidrug-resistant organisms (MDRO) infections have been reported which has led to extensive research for their possible causes. Consequently, the aim of this study is to search for possible duodenoscope surface damages that could provide an alternative and plausible source of infections. Materials and Methods: In order to assess both outer and inner surfaces, a duodenoscope was dismantled and samples were taken from the outer resin polymer and from the air/water, elevator, and working (biopsy) channels that were characterized by FTIR, DSC, TGA, AFM, SEM techniques and the antimicrobial activity were tested. Results: Alterations were noticed on both the coating and working channel polymers, with external alterations increasing progressively from the proximal sample to the distal sample near the tip of the scope. However, the results showed that the coating surface was still efficient against bacterial adhesion. Changes in surface texture and also morphological changes were shown. Conclusions: The study describes the impact of routine procedural use and reprocessing cycles on the duodenoscope, showing that these may possibly make it susceptible to bacterial contamination and MDRO biofilm formation due to difficult reprocessing of the altered surfaces.
Primary sclerosing cholangitis is a progressive liver disease characterized by chronic inflammation leading to liver fibrosis and cirrhosis. Even though the exact pathogenesis is still unclear, a combination of autoimmune, environmental, and ischemic factors could explain certain aspects of the disease. The most important diagnostic step is cholangiography, which can be obtained either by endoscopic retrograde cholangiopancreatography (ERCP), magnetic resonance cholangiography (MRCP as the gold standard), or percutaneous transhepatic cholangiography. It shows multifocal short biliary duct strictures leading to the “beaded” aspect. Cholangiocarcinoma and colorectal adenocarcinoma are the most feared complications in patients with Primary sclerosing cholangitis (PSC). Continuous screening consists of annual clinical, biochemical, and ultrasound assessments in asymptomatic patients and annual colonoscopy in patients with PSC and inflammatory bowel disease. In newly diagnosed patients with PSC, colonoscopy is mandatory and, if negative, then, a repeat colonoscopy should be performed in 3–5 years. The lack of efficient curative medical treatment makes invasive treatments such as liver transplant and endoscopy the mainstream for managing PSC and its complications. Until now, even though only ursodeoxycholic acid has shown a moderate clinical, biochemical, and even histological improvement, it has no significant influence on the risk of cholangiocarcinoma, liver transplant need, or death risk and it is no longer recommended in treating early PSC. Further studies are in progress to establish the effect of molecular-targeted therapies in PSC.
Background and Aims: The fully-covered, lumen apposing metal stents are designed for one step placement, facilitating the direct endoscopic necrosectomy into the walled-off pancreatic necrosis. However, the prediction of the number of necrosectomy sessions in these patients is not known. This study evaluated the association between the proportion of solid necrotic material inside walled-off necrosis, as assessed during the endosonography placement of a lumen apposing metal stent, and the number of necrosectomies subsequently required. Methods: Patients from three tertiary medical centers with symptomatic walled off pancreatic necrosis (pain, infection, gastric/biliary obstruction) at more than 4 weeks after onset of acute pancreatitis were retrospectively analysed. Proportion of solid necrotic debris was estimated during endosonography procedure of lumen apposing metal stents placement. Necrosectomy was performed when obstruction or inflammation occurred subsequently. Lumen apposing metal stents were removed after clearance of necrotic content. Results: In 46 patients with successful lumen apposing metal stents placement, necrosectomy was performed in 39 patients (72.78%). Performance of 3 or more necrosectomies was significantly associated with more than 50% pancreatic necrosis (p=0.032), but not with walled-off pancreatic necrosis size or location. Necrotic infection during lumen apposing metal stents stenting was associated with hypoalbuminemia, but not with necrosectomy requirement. Clinical success after a median follow-up of 13.37 months was 87%. Conclusions: Walled-off pancreatic necrosis with more than 50% solid necrotic content were associated with more necrosectomy procedures, requiering longer endoscopy time, intravenous sedations, and higher costs.
