Endoscopic ultrasonography (EUS) is a versatile tool that can be used to perform a variety of diagnostic and therapeutic procedures in the upper or lower gastrointestinal tract. The proximity of the echoendoscope to the pancreas, liver, and other thoracic and abdominal organs allows detailed examination or minimally invasive intervention that would not be feasible by surgical or percutaneous approaches. EUS is available with radial or linear scanning arrays and is capable of guiding fine-needle aspiration to acquire tissue for cytologic analysis. This review covers the role of EUS in chronic pancreatitis; pancreatic cysts; submucosal tumors; suspected choledocholithiasis; fecal incontinence; staging of malignancy in esophageal, pancreatic, gastric, and rectal cancer; celiac plexus block/neurolysis; fiducial placement; pseudocyst drainage and cystogastrostomy/cystoduodenostomy; endoscopic necrosectomy; and biliary drainage. Figures show peripancreatic cysts, gastrointestinal stromal tumor, common bile duct stone, esophageal adenocarcinoma, pancreatic head mass causing biliary obstruction and invading portal confluence, fine-needle aspiration of a pancreatic head mass, rectal adenocarcinoma, abdominal aorta with celiac artery and superior mesenteric artery, celiac plexus neurolysis, necrosectomy, and EUS-guided choledochoduodenostomy for failed endoscopic retrograde cholangiopancreatography. Tables list the Rosemont criteria for chronic pancreatitis and pancreatic cystic lesions.   Key words: bile duct stone, biliary drainage, echoendoscope, endoscopic ultrasonography, fine-needle aspiration, pancreatic cyst   This review contains 12 highly rendered figures, 2 tables, and 62 references.

BACKGROUND: Endoscopic ultrasound (EUS) with fine-needle aspiration (FNA) is often used to assist in the evaluation of pancreatic lesions and may help to diagnose benign versus malignant neoplasms. However, there is a paucity of literature regarding comparative EUS characteristics of various malignant pancreatic neoplasms (primary and metastatic).OBJECTIVE: To compare and characterize primary pancreatic adenocarcinoma versus other malignant neoplasms, hereafter referred to as nonprimary pancreatic adenocarcinoma (NPPA), diagnosed by EUS-guided FNA.METHODS: The present study was a retrospective analysis of a prospectively maintained database. The setting was a tertiary care, academic medical centre. Patients referred for suspected pancreatic neoplasms were evaluated. Based on EUS-FNA characteristics, primary pancreatic adenocarcinoma was differentiated from other malignant neoplasms. The subset of other neoplasms was defined as malignant lesions that were ‘NPPAs’ (ie, predominantly solid or solid/cystic based on EUS appearance and primary malignant lesions or metastatic lesions to the pancreas). Pancreatic masses that were benign cystic lesions (pseudocyst, simple cyst, serous cystadenoma) and focal inflammatory lesions (acute, chronic and autoimmune pancreatitis) were excluded.RESULTS: A total of 230 patients were evaluated using EUS-FNA for suspected pancreatic mass lesions. Thirty-eight patients were excluded because they were diagnosed with inflammatory lesions or had purely benign cysts. One hundred ninety-two patients had confirmed malignant pancreatic neoplasms (ie, pancreatic adenocarcinoma [n=144], NPPA [n=48]). When comparing adenocarcinoma with NPPA lesions, there was no significant difference in mean age (P=0.0675), sex (P=0.3595) or average lesion size (P=0.3801). On average, four FNA passes were necessary to establish a cytological diagnosis in both lesion subtypes (P=0.396). Adenocarcinomas were more likely to be located in the pancreatic head (P=0.0198), whereas masses in the tail were more likely to be NPPAs (P=0.0006). Adenocarcinomas were also more likely to exhibit vascular invasion (OR 4.37; P=0.0011), malignant lymphadenopathy (P=0.0006), pancreatic duct dilation (OR 2.4; P=0.022) and common bile duct dilation (OR 2.87; P=0.039).CONCLUSIONS: Adenocarcinoma was more likely to be present in the head of the pancreas, have lymph node and vascular involvement, as well as evidence of pancreatic duct and common bile duct obstruction. Of all malignant pancreatic lesions analyzed by EUS-FNA, 25% were NPPA, suggesting that FNA is crucial in establishing a diagnosis and may be helpful in preoperative planning.
