“…Tumors were staged according to the TNM classification. All EUS procedures were performed using a Fujifilm EG-530UT and EG-530UT2 convex array echoendoscope (FUJIFILM Medical Systems, Wayne, NJ, USA) 16 . EUS determined whether the tumor was limited to the sphincter (uT1) or invading the duodenal wall (uT2) ( Table 1 and Fig.…”

“…Endoscopic ultrasound (EUS) is the best imaging modality for investigation of the papillary region and biliopancreatic confluence. The TN staging of papillary tumors is effective and, along with the investigation of the common bile duct (CBD) and the main pancreatic duct (MPD), reinforces the indication for EP by accurately showing that the tumor is confined to the papilla [13][14][15][16][17] . The present study was therefore designed to evaluate factors associated with the occurrence of AP in a controlled group of patients with tumors of the DP subjected to EP.…”

Acute pancreatitis (Ap) is a common adverse event (Ae) of endoscopic papillectomy (ep). prophylactic plastic pancreatic stent (ppS) placement appears to prevent Ap. We evaluated factors associated with post-ep Ap by a retrospective analysis of patients with tumors of the duodenal papilla who underwent EP from January 2008 to November 2016 at 2 tertiary care centers. Clinical, laboratory, endoscopic ultrasound parameters, and ppS placement were evaluated. Seventy-two patients underwent ep (37 men), with mean age of 60.3 (31-88) years. Mean main pancreatic duct (MPD) diameter was 0.44 (0.18-1.8) cm. Mean tumor size was 1.8 (0.5-9.6) cm. Tumors were staged as uT1N0, uT2N0, and uT1N1 in 87.5%, 11.1%, and 1.4%. Thirty-eight AEs occurred in 33 (45.8%) patients, with no mortality. Total bilirubin, tumor size, MPD diameter, and PPS placement had odds ratios (ORs) of 0.82, 0.14, 0.00, and 6.43 for AP. Multivariate analysis (PPS placement × MPD diameter) showed ORs of 4.62 (95%CI, 1.03-21.32; p = 0.049) and 0.000 (95%CI, 0.00-0.74; p = 0.042) for AP. In conclusion, patients with jaundice, large tumors, and dilated MPD seem less likely to have post-EP AP. PPS placement was associated with a higher risk of Ap, which may question its use.

“…Endoscopic US (EUS) has gained importance, and detailed knowledge has been published. [ 14 15 16 17 ] Comparatively, little is known about the use of contrast-enhanced EUS (CE-EUS). [ 18 19 20 21 22 ] The first pilot study performed in 2003 described an experimental technique of CE-EUS based on a linear prototype EUS scope, using a low mechanical index (MI) (0.09–0.25) and a second-generation contrast agent (SonoVue ® ), which allowed the visualization of early arterial phase and late parenchymal phase enhancement of the pancreas.…”

Dynamic contrast-enhanced ultrasound (DCE-US) has been recently standardized by guidelines and recommendations. The European Federation of Societies for US in Medicine and Biology position paper describes the use for DCE-US. Comparatively, little is known about the use of contrast-enhanced endoscopic US (CE-EUS). This current paper reviews and discusses the clinical use of CE-EUS and DCE-US. The most important clinical use of DCE-US is the prediction of tumor response to new drugs against vascular angioneogenesis.

“…Although USG is considered the gold standard for GB imaging, in view of providing high resolution images; EUS has been found to be better than USG for GB lesions imaging[ 3 - 6 ]. Different techniques of imaging by EUS have been described by different authors for GB imaging but a standardized technique has not been mentioned[ 7 - 10 ]. In view of close proximity of GB to the duodenum, usually EUS imaging is restricted to duodenum[ 11 ].…”

Endoscopic ultrasonography (EUS) is considered a superior investigation when compared to conventional ultrasonography for imaging gall bladder (GB) lesions as it can provide high-resolution images of small lesions with higher ultrasound frequencies. Examination of GB is frequently the primary indication of EUS imaging. Imaging during EUS may not remain restricted to one station and multi-station imaging may provide useful information. This review describes the techniques of imaging of GB by linear EUS from three different stations. The basic difference of imaging between the three stations is that effective imaging from station 1 is done above the neck of GB, from station 2 at the level of the neck of GB and from station 3 below the level of the neck of GB.
