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)...

More than half of primary lung cancers are not resectable at diagnosis and 40% of deaths may be secondary to loco-regional disease. Many of these patients suffer from symptoms related to airways obstruction. Indications for therapeutic endoscopic treatment are palliation of dyspnea and other obstructive symptoms in advanced cancerous lesions and cure of early lung cancer. Bronchoscopic management is also indicated for all those patients suffering from benign or minimally invasive neoplasm who are not suitable for surgery due to their clinical conditions...

Endoscopic ultrasound (EUS) was first introduced into medical practice in 1980s as a diagnostic imaging modality for pancreatic pathology. EUS has the unique advantage of combining ultrasound and endoscopy to obtain detailed information of the gastrointestinal tract. Over the past decade, the use of EUS in liver diseases has been increasing. EUS, which was initially used as a diagnostic tool, is now having increasing therapeutic role as well. We provide a review of the application of EUS in the diagnostic and therapeutic aspects of liver disease...

AIM: To evaluate the accuracy of the elastography score combined to the strain ratio in the diagnosis of solid pancreatic lesions (SPL). METHODS: A total of 172 patients with SPL identified by endoscopic ultrasound were enrolled in the study to evaluate the efficacy of elastography and strain ratio in differentiating malignant from benign lesions. The semi quantitative score of elastography was represented by the strain ratio method. Two areas were selected, area (A) representing the region of interest and area (B) representing the normal area...

AIM: To evaluate endoscopic ultrasound (EUS)-guided biopsies for the pretreatment characterization of gastrointestinal stromal tumors (GIST) to personalize the management of patients. METHODS: All patients with lesions suspected to be GIST who were referred for EUS-sampling at a tertiary Swedish center were eligible for inclusion 2006-2015. During the observational study phase (2006-2011), routine fine-needle-aspiration (EUS-FNA) was performed. In 2012-2015, we converted to an interventional, randomized protocol with dual sampling EUS-FNA and fine-needle-biopsy-sampling (EUS-FNB) for all lesions...

Patients with biliary strictures often represent a diagnostic and therapeutic challenge, due to the site and complexity of biliary obstruction and wide differential diagnosis. Multidisciplinary decision making is required to reach an accurate and timely diagnosis and to plan optimal care. Developments in endoscopic ultrasound and peroral cholangioscopy have advanced the diagnostic yield of biliary endoscopy, and novel optical imaging techniques are emerging. Endoscopic approaches to biliary drainage are preferred in most scenarios, and recent advances in therapeutic endoscopic ultrasound allow drainage where the previous alternatives were only percutaneous or surgical...

RATIONALE: Pancreatic acinar cell carcinoma (ACC) is a rare malignant tumor of exocrine pancreas. It is typically a well-marginated large solid mass arising in a certain aspect of the pancreas. Diffuse involvement of ACC in the pancreas is very rare, and may simulate pancreatitis in radiological findings. We report 2 cases of ACC presenting as diffuse enlargement of the pancreas due to tumor involvement without formation of a distinct mass. PATIENT CONCERNS: The patients consisted of a 41-year-old man with weight loss and a 77-year-old man who was asymptomatic...

INTRODUCTION: Transversus abdominis plane (TAP) block is now a well-established technique in post-operative analgesia for lower abdominal surgeries. We evaluated the effect of ultrasound-guided TAP block on recovery parameters in patients undergoing endoscopic repair of abdominal wall hernia. METHODS: Thirty adults were randomised to receive either ropivacaine with dexmedetomidine (TR) or saline (TP) in TAP block, before emergence from anaesthesia. The patients were assessed for pain relief, sedation, time to ambulate (TA), discharge readiness (DR), postoperative opioid requirement and any adverse events...

A 56-year-old man presented with a chest computed tomography (CT) finding of a right upper lobe nodule, which was diagnosed using brush cytology as adenocarcinoma stage IB (cT2aN0M0). Repeat CT scan for preoperative evaluation revealed a small, slightly hypodense spot in the pancreatic body, which was diagnosed as pancreatic metastasis from lung cancer using endoscopic ultrasound-guided fine needle aspiration biopsy (EUS-FNAB). Because of the presence of distant metastasis, surgical resection was deferred and chemotherapy was chosen instead...

Increased early detection and personalized therapy for lung cancer have coincided with greater use of minimally invasive sampling techniques such as endobronchial ultrasound-guided biopsy (EBUS), endoscopic ultrasound-guided biopsy (EUS), and navigational biopsy, as well as thin needle core biopsies. As many lung cancer patients have late stage disease and other comorbidities that make open surgical procedures hazardous, the least invasive biopsy technique with the highest potential specimen yield is now the preferred first diagnostic study...

A workshop was sponsored by the National Institute of Diabetes and Digestive and Kidney Diseases to address the research gaps and opportunities in pancreatic endoscopic ultrasound (EUS). The event occurred on July 26, 2017 in 4 sessions: (1) benign pancreatic diseases, (2) high-risk pancreatic diseases, (3) diagnostic and therapeutics, and (4) new technologies. The current state of knowledge was reviewed, with identification of numerous gaps in knowledge and research needs. Common themes included the need for large multicenter consortia of various pancreatic diseases to facilitate meaningful research of these entities; to standardize EUS features of different pancreatic disorders, the technique of sampling pancreatic lesions, and the performance of various therapeutic EUS procedures; and to identify high-risk disease early at the cellular level before macroscopic disease develops...

Background and study aims  Tumor seeding after endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is rare. A 53-year-old man underwent transesophageal EUS-FNA for diagnosis of a 6-cm mass in the mediastinum as seen by computed tomography (CT). Four weeks later, repeat CT scan revealed a mass in the esophageal wall. Upper gastrointestinal endoscopy confirmed a lesion in the mid-esophagus, which was biopsied and found to be consistent with needle tract seeding after EUS-FNA. Tumor seeding in the gastrointestinal wall or peritoneum after EUS-FNA is rare, but may adversely affect the prognosis...

An 80-year-old man presented with a right side lung tumor. The tumor was not abutting the bronchus or chest wall; thus, endobronchial ultrasound (EBUS) and CT-guided biopsy were considered to be technically difficult. We therefore attempted endoscopic ultrasound-guided fine needle aspiration (EUS-FNA). Although the nodule was not abutting the esophagus on CT, an irregularly shaped hypoechoic lesion was visualized on EUS. EUS-FNA was successfully performed. The tumor was diagnosed as squamous cell carcinoma...

A 59-year-old man was admitted to the hospital with acute pancreatitis. The cause was suggested to be a pancreatic tumor based on computed tomography (CT). The pancreatic tumor was 45 mm with an extensive tumor embolism at the trunk of the portal vein and intraductal infiltration of the main pancreatic duct (MPD). The pancreatic tumor was diagnosed as acinar cell carcinoma (ACC) by endoscopic ultrasound guided fine needle aspiration. Therefore, the cause of acute pancreatitis was diagnosed to be intraductal infiltration of ACC in the MPD...

Endoscopic ultrasound (EUS) plays an important role as a diagnostic and therapeutic modality in gastroenterology. New developments have emerged, especially in the last decade, and are being introduced to endoscopists. The ability to readily visualize and access organs in the gastrointestinal tract has allowed endoscopists to perform new interventional procedures. EUS procedures have taken the place of conventional approaches for the treatment of various gastrointestinal diseases, including pancreatic cystic lesions...

Therapeutic endoscopic ultrasound is a rapidly expanding field, requiring training beyond the 3-year gastroenterology fellowship and at least an additional year in a structured advanced endoscopy fellowship program with mentorship from an expert at a sufficiently high-volume center. Simulation models can provide initial instruction on technique and increase familiarity with the rapidly changing devices. Trainees must also be given a graduated level of independence to perform each step and, eventually, be able to practice on a variety of endoscopic targets...

SriHari Mahadev, David S Lee
Pelvic fluid collections can be challenging and often inaccessible because of their location and close proximity to adjacent organs and spine. This causes an increased risk for morbidity and poor outcomes. Recent advances in endoscopic ultrasound and therapeutic devices provide an effective, safe, and minimally invasive option to surgery or interventional radiology. These devices offer a relatively pain-free method that has shown good outcomes with minimal risk in recent case series, and has increasingly become the first-line treatment of choice...

Gastric outlet obstruction is a common complication of advanced upper gastrointestinal and pancreatic malignancies. Endoscopic ultrasound (EUS)-guided gastrojejunostomy is a new option that may provide a more durable solution than enteral stenting with shorter recovery time and less cost than surgical gastrojejunostomy. Techniques to perform this procedure include direct EUS-guided puncture and balloon-assisted and free-hand methods. Use of cautery-tipped lumen-apposing metal stent results in higher rates of technical success and shorter procedure times...
