    • Background: Current guidelines recommend CT scan or magnetic resonance imaging as the initial imaging modalities for the work-up of suspected pancreatic neuroendocrine tumors (PNETs). Objective: To determine the incremental benefit of preoperative EUS (IBEUS) for the detection of suspected PNETs after other investigative modalities have been attempted. Design: This systematic review searched MEDLINE, EMBASE, bibliographies of included articles, and conference proceedings for studies reporting original data regarding the preoperative detection of PNETs. Pooled IBEUS was calculated by using random effects models. Heterogeneity was explored by using stratified meta-analysis and meta-regression. Evidence of small-study effects was assessed by using funnel plots and the Begg test. Patients: Patients with suspected PNETs. Interventions: EUS evaluation. Main Outcome Measurements: The pooled IBEUS for the detection of PNETs after CT scan, with or without additional investigative modalities. Results: Among 4505 citations identified, we included 17 cohort studies (612 patients). EUS identified PNETs in 97% of cases. Improved PNET identification with EUS was observed in all of the studies. After adjusting for small-study effects, meta-analysis showed that EUS alone could identify PNETs in approximately 1 in 4 patients (adjusted IBEUS 26%; 95% confidence interval, 17%-37%). The pooled IBEUS varied based on the study design, study size, type of CT scan used, and the number of modalities used prior to EUS. Limitations: The majority of included studies were retrospective. Small-study effects were observed. Conclusion: Preoperative EUS is associated with an increase in PNET detection after other modalities are attempted.

  • Clinical prediction rule to determine the need for repeat ERCP after endoscopic treatment of postsurgical bile leaks
  • 2017
  • Ingår i: Gastrointestinal Endoscopy. - MOSBY-ELSEVIER. - 0016-5107 .- 1097-6779. ; 85:5, s. 1047-1056
  • Tidskriftsartikel (refereegranskat)abstract
    • Background and Aims: In patients who have undergone ERCP with biliary stenting for postsurgical bile leaks, the optimal method (ERCP or gastroscopy) and timing of stent removal is controversial. We developed a clinical prediction rule to identify cases in which a repeat ERCP is unnecessary.Methods: Population-based study of all patients who underwent ERCP for management of surgically induced bile leaks between 2000 and 2012. Multivariate and binary recursive partitioning analyses were performed to generate a rule predicting the absence of biliary pathology on repeat endoscopic evaluation.Results: A total of 259 patients were included. On multivariate analysis, postsurgical normal alkaline phosphatase (ALP; OR, 2.26; 95% CI, 1.03-4.99), time from surgery to first ERCP < 8 days (OR, 2.47; 95% CI, 1.15-5.31), and minor leak with no other pathology on initial ERCP (OR, 6.74; 95% CI, 1.75-25.89) were independently associated with the absence of persistent bile leak and other pathology on repeat ERCP. The derived rule included laparoscopic cholecystectomy, normal postsurgical ALP, minor leak with no other pathology on initial ERCP, and an interval from initial to repeat ERCP between 4 and 8 weeks. When all 4 criteria were met, the rule had a sensitivity of 94% (95% CI, 83%-99%) and a negative predictive value of 93% (95% CI, 81%-99%). Optimism-adjusted sensitivity and negative predictive value were 88% (95% CI, 76%-96%) and 86% (95% CI, 73%-96%), respectively.Conclusions: This clinical decision rule identifies patients who can have their biliary stents removed via gastroscopy, which may improve patient safety and healthcare utilization.
