Research paper thumbnail of Pancreatic necrosectomy: an evidence-based systematic review of the levels of evidence and a comparison of endoscopic versus non-endoscopic techniques

The aims of this systematic review are to record the entire body of the literature accumulated over the past 15 years on endoscopic necrosectomy techniques and to compare the outcomes of endoscopic versus non-endoscopic techniques. All relevant articles were extracted up to December 2015 based on the results of searches in PubMed, Scopus and Google Scholar. A total of 46 pertinent articles were finally included for the purpose of this systematic review. Most of the studies in our review included small numbers of patients, were retrospective and had low/moderate overall levels of evidence. The mean technical and clinical success rates reported were 99% and 89%, respectively, the mean overall complication rate was 22% and the mean overall mortality rate was 5%. The most common complications were bleeding, which occurred in 11% of patients, perforations/pneum...

Ideally, treatment should be individualized, based on the projected treatment outcome for that individual. Accurate staging of the extent of the disease at the time of diagnosis offers the most rational attempt at stratifying patients into categories that can be used to affect treatment choices. Endoscopic ultrasonography (EUS) is the most accurate nonoperative technique for determining the depth of tumour infiltration and thus is accurate in predicting which patients will be able to undergo complete resection. EUS is also being used for tumour staging in order to guide treatment decisions in patients with esophageal cancer.

Research paper thumbnail of Reliability of endoscopic ultrasound in predicting the number and size of common bile duct stones before endoscopic retrograde cholangiopancreatography

To evaluate the concordance between EUS and endoscopic retrograde cholangiopancreatography (ERCP) in stone number and size assessment. We performed a retrospective analysis of consecutive patients undergoing ERCP due to detection of choledocholithiasis by EUS. Concordance between EUS and ERCP was defined as difference in stone diameter <30% and perfect match in stone number. Among 116 patients, 25% had sludge, 37.9% had single and 37.1% had multiple stones. Overall concordance was 62.9%. Sludge was correctly assessed in 85.7%, single stone in 81.3% and multiple stones in 45.1% (P=0.0001). EUS was accurate in 78.8% of patients who underwent both procedures in the same session, but only in 61.9% in those who underwent ERCP within 1 week. Multivariate analysis identified the single-session approach (odds ratio 2.894; P=0.035) and multiple stones (odds ratio 0.244; P=0.001) as independent predictors of concordance. Concordance between EUS and ERCP was correlated to the single session approach and inversely correlated to the presence of multiple stones. EUS may predict potentially difficult ERCP allowing to plan the best treatment strategy.

These include EUS-guided drainage of pancreatic fluid collections, EUS-guided necrosectomy, EUS-guided cholangiography and biliary drainage, EUS-guided pancreatography and pancreatic duct drainage, EUS-guided gallbladder drainage, EUS-guided drainage of abdominal and pelvic fluid collections, EUS-guided celiac plexus block and celiac plexus neurolysis, EUS-guided pancreatic cyst ablation, EUS-guided vascular interventions, EUS-guided delivery of antitumoral agents and EUS-guided fiducial placement and brachytherapy. However these procedures are technically challenging and require expertise in both EUS and interventional endoscopy, such as endoscopic retrograde cholangiopancreatography and gastrointestinal stenting. We undertook a systematic review to record the entire body of literature accumulated over the pas...

Research paper thumbnail of Serum trypsin-like immunoreactivity after endoscopic retrograde cholangiopancreatography

None of the patients developed clinical acute pancreatitis. Generally, the serum TLI peak was observed within the first 6 hours after the examination. Most patients (73%) showed a pathologically high TLI but very high values were not frequent (19%). Successful pancreatic opacification was followed by a significant increase in serum TLI which was pathologically high in nearly all cases (18/20). On the contrary, after cholangiography alone abnormal values were less frequent (4/8) and the increase was not significant. In most patients TLI and amylase responses were in agreement. A significant, though poor, linear relation was found between serum TLI and serum amylase 3, 6 and 12 hours after the examination.

Our aim was to assess the interobserver agreement (IA) in CH-EUS. Methods: Fifteen endosonographers (8 experienced and 7 non-experienced) from 11 Italian EUS centers evaluated 80 video-cases (40 solid pancreatic lesions, 20 pancreatic cystic lesions and 20 submucosal lesions) of CH-EUS, according to the degree of enhancement, the pattern of distribution and the washout of the contrast agent. IA within each group and between the 2 groups of observers was assessed with the Fleiss kappa statistic. Results: Overall IA was moderate for the uptake and fair for the pattern of distribution and the washout. In solid pancreatic lesions, IA was moderate for the uptake and fair for the pattern and the washout. In cystic pancreatic lesions, IA was uniformly moderate for the assessment of uptake, slight for the pattern and fair for th...
