For routine EUS-guided sampling of solid masses and lymph nodes (LNs) ESGE recommends 25G or 22G needles (high quality evidence, strong recommendation); fine needle aspiration (FNA) and fine needle biopsy (FNB) needles are equally recommended (high quality evidence, strong recommendation).When the primary aim of sampling is to obtain a core tissue specimen, ESGE suggests using 19G FNA or FNB needles or 22G FNB needles (low quality evidence, weak recommendation).ESGE recommends using 10-mL syringe suction for EUS-guided sampling of solid masses and LNs with 25G or 22G FNA needles (high quality evidence, strong recommendation) and other types of needles (low quality evidence, weak recommendation). ESGE suggests neutralizing residual negative pressure in the needle before withdrawing the needle from the target lesion (moderate quality evidence, weak recommendation).ESGE does not recommend for or against using the needle stylet for EUS-guided sampling of solid masses and LNs with FNA needles (high quality evidence, strong recommendation) and suggests using the needle stylet for EUS-guided sampling with FNB needles (low quality evidence, weak recommendation).ESGE suggests fanning the needle throughout the lesion when sampling solid masses and LNs (moderate quality evidence, weak recommendation).ESGE equally recommends EUS-guided sampling with or without on-site cytologic evaluation (moderate quality evidence, strong recommendation). When on-site cytologic evaluation is unavailable, ESGE suggests performance of three to four needle passes with an FNA needle or two to three passes with an FNB needle (low quality evidence, weak recommendation).For diagnostic sampling of pancreatic cystic lesions without a solid component, ESGE suggests emptying the cyst with a single pass of a 22G or 19G needle (low quality evidence, weak recommendation). For pancreatic cystic lesions with a solid component, ESGE suggests sampling of the solid component using the same technique as in the case of other solid lesions (low quality evidence, weak recommendation).ESGE does not recommend antibiotic prophylaxis for EUS-guided sampling of solid masses or LNs (low quality evidence, strong recommendation), and suggests antibiotic prophylaxis with fluoroquinolones or beta-lactam antibiotics for EUS-guided sampling of cystic lesions (low quality evidence, weak recommendation). ESGE suggests that evaluation of tissue obtained by EUS-guided sampling should include histologic preparations (e. g., cell blocks and/or formalin-fixed and paraffin-embedded tissue fragments) and should not be limited to smear cytology (low quality evidence, weak recommendation).

AbstractText: A 61-year-old man presented with upper abdominal pain and jaundice. Abdominal computed tomography imaging revealed stones in the gallbladder and the common bile duct, with a thickening of the gallbladder wall and an obvious increase in the volume of the gallbladder. Initial treatment using endoscopic retrograde cholangiopancreatography failed due to the presence of surgically altered gastrointestinal anatomy.

GOALS: The goal of this study was to evaluate outcomes of colonoscopy in the setting of post myocardial infarction (MI) gastrointestinal bleeding (GIB) in a large population-based data set. BACKGROUND: The literature to substantiate the proposed safety of colonoscopy following an acute MI is limited. STUDY: The Nationwide Inpatient Sample (2007 to 2013) was utilized to identify all adult patients (age, 18 y or above) hospitalized with a primary diagnosis of ST-elevation MI and receiving left heart catheterization (STEMI-C). The outcomes of patients with concomitant diagnosis of GIB receiving endoscopic intervention with esophagogastroduodenoscopy (EGD) or colonoscopy postcatheterization were compared with those who did not. Primary outcomes including mortality, length of stay, and hospital costs were evaluated with univariate and multivariate analysis. RESULTS: There were 131,752 patients with post-STEMI-C GIB (5.35% of all STEMI-C patients) and same admission colonoscopy was performed in 1599 patients (1.21%). Although the prevalence of post-STEMI-C GIB increased from 4.27% in 2007 to 5.87% in 2013 (P<0.001), patients receiving colonoscopy decreased from 1.42% to 1.09% (P<0.001) over the course of the study period. Multivariate analysis revealed that patients receiving no endoscopic intervention [odds ratio, 3.61; 95% confidence interval: 1.57, 8.31] or EGD alone (OR, 2.70; 95% confidence interval: 1.12, 6.49) have higher mortality compared with those receiving colonoscopy. CONCLUSIONS: Same admission colonoscopy performed for post-STEMI-C GIB was associated with lower mortality. However, despite increased incidence of GIB in these patients during the study period, a lower percentage of patients received colonoscopy. These results suggest that colonoscopy is safe but underutilized in this setting.

Background and study aims Linear endoscopic ultrasound (EUS) evaluation of the pancreaticobiliary system usually requires scanning from both the stomach and the duodenum. The feasibility of assessing the complete pancreaticobiliary system from the stomach alone has not been studied. We aimed to conceptualize a system-based approach (the railroad approach) for linear pancreaticobiliary EUS (PB-EUS) and evaluate whether the pancreaticobiliary anatomy could be assessed from the stomach alone. Patients and methods Three maneuvers were conceptualized and evaluated (the alpha maneuver in the stomach, and sigma and xi maneuvers in the duodenum). The maneuvers were prospectively evaluated in 100 consecutive patients requiring PB-EUS.  Results The median procedure time for the three maneuvers was significantly higher than that for the alpha maneuver alone (12 vs. 6 minutes; P ≤ 0.001). The visualization rate of the hilum and common hepatic duct was significantly higher from the stomach than from the duodenum (100 % vs. 83.5 %; P ≤ 0.001), while rates for the head of the pancreas (100 % vs 100 %) and uncinate process (100 % vs 100 %) did not differ. The suprapancreatic common bile duct (CBD; 92 % vs 100 %; P = 0.006), retropancreatic CBD (95 % vs 100 %; P = 0.06), and pancreatic duct in the head (94 % vs 100 %; P = 0.03) were not completely visualized from the stomach, because of pancreatic calcification or shadow from the ligaments. The EUS diagnosis made from the stomach and duodenum did not differ after excluding body and tail lesions (pancreatic head neoplasms, 100 % vs 100 %; CBD stone, 100 % vs 84.6 %; pancreatic cysts in the head, 83.3 % vs 83.3 %, respectively). Conclusions Adequate anatomical and diagnostic information on the pancreaticobiliary system may be acquired by EUS scanning from the stomach alone and with a shorter procedure time.

BACKGROUND: Faecal calprotectin (FC) measurement distinguishes patients with inflammatory bowel disease (IBD) from those with irritable bowel syndrome but evidence of its performance in primary care is limited. AIMS: To assess the yield of IBD from FC testing in primary care. METHODS: Retrospective review of hospital records to assess the outcome following FC testing in primary care. Investigations for all patients undergoing FC testing in a single laboratory for 6 months from 1 October 2013 to 28 February 2014 were reviewed. RESULTS: 410 patients (162 male; median age 42; range 16-91) were included. FC>50 µg/g was considered positive (FC+). 148/410 (36.1%; median age 44 (17-91)) were FC+ (median FC 116.5 µg/g (51-1770)). 122/148 FC-positive patients (82.4%) underwent further investigation. 97 (65.5%) underwent lower gastrointestinal endoscopy (LGIE), of which 7 (7.2%) had IBD. 49/262 (18.7%) FC-negative (FC-) patients (FC ≤50 µg/g) (median age 47 (19-76)) also underwent LGIE, of whom 3 (6.1%) had IBD.IBD was diagnosed in 11/410 (2.7%; 4 ulcerative colitis, 3 Crohn's disease, 4 microscopic colitis). 8/11 were FC+ (range 67-1170) and 3 FC-. At a 50 µg/g threshold, sensitivity for detecting IBD was 72.7%, specificity 64.9%, positive predictive value (PPV) 5.41% and negative predictive value 98.9%. Increasing the threshold to 100 µg/g reduced the sensitivity of the test for detecting IBD to 54.6%. CONCLUSIONS: FC testing in primary care has low sensitivity and specificity with poor PPV for diagnosing IBD. Its use needs to be directed to those with a higher pretest probability of disease. Local services and laboratories should advise general practitioners accordingly.

OBJECTIVES: To quantitatively and qualitatively assess abdominal arterial and venous phase contrast-enhanced spectral detector computed tomography (SDCT) virtual mono-energetic (MonoE) datasets in comparison to conventional CT reconstructions provided by the same system. MATERIALS AND METHODS: Conventional and MonoE images at 40-120 kilo-electron volt (keV) levels with a 10 keV increment as well as 160 and 200 keV were reconstructed in abdominal SDCT datasets of 55 patients. Attenuation, image noise, and contrast- / signal-to-noise ratios (CNR, SNR) of vessels and solid organs were compared between MonoE and conventional reconstructions. Two readers assessed contrast conditions, detail visualization, overall image quality and subjective image noise with both, fixed and adjustable window settings. RESULTS: Attenuation, CNR and SNR of vessels and solid organs showed a stepwise increase from high to low keV reconstructions in both contrast phases while image noise stayed stable at low keV MonoE reconstruction levels. Highest levels were found at 40 keV MonoE reconstruction (p<0.001), respectively. Solid abdominal organs showed a stepwise decrease from low to high energy levels in regard to attenuation, CNR and SNR with significantly higher values at 40 and 50 keV, compared to conventional images. The 70 keV MonoE was comparable to conventional poly-energetic reconstruction (p≥0.99). Subjective analysis displayed best image quality for the 70 keV MonoE reconstruction level in both phases at fixed standard window presets and at 40 keV if window settings could be adjusted. CONCLUSION: SDCT derived low keV MonoE showed markedly increased CNR and SNR values due to constantly low image noise values over the whole energy spectrum from 40 to 200 keV.
