Early endoscopic ultrasonography in acute biliary pancreatitis: A prospective pilot study.

ABSTRACT: To investigate the clinical usefulness of early endoscopic ultrasonography (EUS) in the management of acute biliary pancreatitis (ABP).All consecutive patients entering the emergency department between January 2010 and December 2012 due to acute abdominal pain and showing biochemical and/or radiological findings consistent with possible ABP were prospectively enrolled. Patients were classi?ed as having a low, moderate, or high probability of common bile duct (CBD) stones, according to the established risk strati?cation. Exclusion criteria were: gastrectomy or patient in whom the cause of biliary obstruction was already identified by ultrasonography. All enrolled patients underwent EUS within 48 h of their admission. Endoscopic retrograde cholangiopancreatography was performed immediately after EUS only in those cases with proven CBD stones or sludge. The following parameters were investigated: (1) clinical: age, sex, fever; (2) radiological: dilated CBD; and (3) biochemical: bilirubin, AST, ALT, gGT, ALP, amylase, lipasis, PCR. Association between presence of CBD stone at EUS and the individual predictors were assessed by univariate logistic regression. Predictors significantly associated with CBD stones (P < 0.05) were entered in a multivariate logistic regression model.A total of 181 patients with pancreatitis were admitted to the emergency department between January 2010 and December 2012. After exclusion criteria a total of 71 patients (38 females, 53.5%, mean age 58 ± 20.12 years, range 27-89 years; 33 males, 46.5%, mean age 65 ± 11.86 years, range 41-91 years) were included in the present study. The probability of CBD stones was considered low in 21 cases (29%), moderate in 26 (37%), and high in the remaining 24 (34%). The 71 patients included in the study underwent EUS, which allowed for a complete evaluation of the target sites in all the cases. The procedure was completed in a mean time of 14.7 min (range 9-34 min), without any notable complications.The overall CBD stone frequency was 44% (31 of 71), with a significant increase from the group at low pretest probability to that at moderate (OR = 5.79, P = 0.01) and high (OR = 4.25, P = 0.03) pretest probability.Early EUS in ABP allows, if appropriate, immediate endoscopic treatment and significant spare of unnecessary operative procedures thus reducing possible related complications.

Project description:IntroductionIdiopathic acute pancreatitis (IAP) remains a dilemma for physicians as it is uncertain whether patients with IAP may actually have an occult aetiology. It is unclear to what extent additional diagnostic modalities such as endoscopic ultrasonography (EUS) are warranted after a first episode of IAP in order to uncover this aetiology. Failure to timely determine treatable aetiologies delays appropriate treatment and might subsequently cause recurrence of acute pancreatitis. Therefore, the aim of the Pancreatitis of Idiopathic origin: Clinical added value of endoscopic UltraSonography (PICUS) Study is to determine the value of routine EUS in determining the aetiology of pancreatitis in patients with a first episode of IAP.Methods and analysisPICUS is designed as a multicentre prospective cohort study of 106 patients with a first episode of IAP after complete standard diagnostic work-up, in whom a diagnostic EUS will be performed. Standard diagnostic work-up will include a complete personal and family history, laboratory tests including serum alanine aminotransferase, calcium and triglyceride levels and imaging by transabdominal ultrasound, magnetic resonance imaging or magnetic resonance cholangiopancreaticography after clinical recovery from the acute pancreatitis episode. The primary outcome measure is detection of aetiology by EUS. Secondary outcome measures include pancreatitis recurrence rate, severity of recurrent pancreatitis, readmission, additional interventions, complications, length of hospital stay, quality of life, mortality and costs, during a follow-up period of 12 months.Ethics and disseminationPICUS is conducted according to the Declaration of Helsinki and Guideline for Good Clinical Practice. Five medical ethics review committees assessed PICUS (Medical Ethics Review Committee of Academic Medical Center, University Medical Center Utrecht, Radboud University Medical Center, Erasmus Medical Center and Maastricht University Medical Center). The results will be submitted for publication in an international peer-reviewed journal.Trial registration numberNetherlands Trial Registry (NL7066). Prospectively registered.

Project description:Endoscopic ultrasound-guided biliary drainage (EUS-BD) has emerged as an alternative to traditional radiologic and surgical drainage procedures after failed endoscopic retrograde cholangiopancreatography (ERCP). However, prospective multicenter data are lacking. The aims of this study were to prospectively assess the short- and long-term efficacy and safety of EUS-BD in patients with malignant distal biliary obstruction.Consecutive patients at 12 tertiary centers (5 US, 5 European, 1 Asian, 1 South American) with malignant distal biliary obstruction and failed ERCP underwent EUS-BD. Technical success was defined as successful stent placement in the desired position. Clinical success was defined as a reduction in bilirubin by 50 % at 2 weeks or to below 3 mg/dL at 4 weeks. Adverse events were prospectively tracked and graded according to the American Society for Gastrointestinal Endoscopy (ASGE) lexicon's severity grading system. Overall survival and duration of stent patency were calculated using Kaplan-Meier analysis.A total of 96 patients (mean age 66 years, female 45 %, pancreatic cancer 55 %) underwent EUS-BD. Stent placement (technical success) was achieved in 92 (95.8 %) patients (metallic stent 84, plastic stent 8). Mean procedure time was 40 minutes. Clinical success was achieved in 86 (89.5 %) patients. A total of 10 (10.5 %) adverse events occurred: pneumoperitoneum (n = 2), sheared wire (n = 1), bleeding (n = 1), bile leak (n = 3), cholangitis (n = 2), and unintentional perforation (n = 1); 4 graded as mild, 4 moderate, 1 severe, and 1 fatal (due to perforation). A total of 38 (44 %) patients died of disease progression during the study period. The median patient survival was 167 days (95 %CI 112 - 221) days. The 6-month stent patency rate was 95 % (95 %CI 94.94 - 95.06 %) and the 1-year stent patency was 86 % (95 %CI 85.74 - 86.26 %).This study on EUS-BD demonstrates excellent efficacy and safety of EUS-BD when performed by experts.NCT01889953.
