As Crohn's disease (CD) is predominantly located within the small bowel, imaging of the small bowel plays an intriguing role in the primary diagnosis as well as in the monitoring of patients with CD. Intestinal ultrasound (IUS) offers several advantages over endoscopy and other imaging modalities. Obvious advantages of IUS include noninvasiveness, rapid availability and cost effectiveness. IUS has been shown to have high accuracy in detecting small bowel CD and determining intra- and extramural complications such as stenoses, fistulae and abscesses...

Background and study aims : Endoscopic retrograde cholangiopancreatography (ERCP) is an effective treatment for pancreaticolithiasis, including use of pancreatoscopy for intraductal electrohydraulic lithotripsy (IEHL). Pancreatoscopy is often limited by a small-caliber downstream pancreatic duct as well as an unstable pancreatoscope position within the pancreatic head. Endoscopic ultrasound-guided pancreaticogastrostomy (EUS-PG) has been developed as a method to relieve ductal obstruction when retrograde access fails...

A 53-year-old man presented with nausea and dysemesia underwent gastroscopy, which revealed a submucosal tumor arising from the esophagus at 25 cm from the incisors, approximately 3.0×3.0 cm in size. Endoscopic ultrasound showed that the lesion originated from the muscularis propria (Figure 1). Submucosal tunneling endoscopic resection [1] was carried out under general anesthesia using a videoendoscope equipped with near-focus function (EVIS-HQ290, Olympus Medical Systems Co. Ltd., Tokyo, Japan) with a transparent cap (D-201-10704, Olympus) attached to the tip...

Background and study aims : Cyanoacrylate glue is recommended first-line endoscopic therapy for gastric fundal varices but it is difficult to use and carries a risk of embolization. Thrombin is preferred by many in the UK, but its effectiveness can be difficult to establish at endoscopy and the rate of re-bleeding is higher. Endoscopic ultrasound (EUS) can help assess variceal blood flow and has the potential to improve both targeting and effectiveness of injection therapy. Whereas there is already some data for its use with glue, little data currently exist in relation to its use with thrombin...

Background: Glomus tumors are uncommon mesenchymal neoplasms originating from modified smooth muscle cells in the glomus body. They are generally small, solitary lesions found in the distal extremities. Rarely, involvement in the abdominal viscera can occur. In such cases, hematemesis/melena and epigastric discomfort are the most common initial symptoms. Although gastric glomus tumors can demonstrate malignant behavior, criteria for identifying malignant potential have yet to be established...

The purpose of this study was to investigate the value of contrast-enhanced ultrasound (CEUS) in the identification of competent and incompetent lower-extremity perforating veins. Patients with chronic venous insufficiency who met the inclusion criteria were enrolled. All patients underwent pre-operative CEUS and color Doppler ultrasound (CDU) and accepted subfascial endoscopic perforator surgery. We compared the numbers of perforator veins identified by CEUS and CDU with the endoscopy result, which was considered the gold standard...

Gastric outlet obstruction (GOO) is a rare condition occurring as a consequence of numerous processes that prevent gastric emptying. Presenting symptoms of GOO are non-specific and include nausea, vomiting, epigastric discomfort and decreased appetite. The diagnosis of GOO is often challenging. Emergency physicians must have a heightened awareness of GOO to ensure proper diagnosis and rapid treatment. Although the gold standard for diagnoses of GOO is endoscopy, many patients are identified by computerized tomography imaging...

Introduction: Choledochal cyst (CDC) is often associated with intrahepatic stones (IHSs) in children which necessitate their removal during excision. The endoscopic equipment needed for their clearance such as paediatric flexible cholangioscope and other advanced modalities are not freely available in resource-poor setups. We describe per-operative modified rigid cholangioscopy using rigid paediatric cystoscope for stone removal during open CDC excision. Methods: All children with CDC presenting with IHSs between January 2015 and December 2017 were included in the present study...

Crohn's disease (CD) and ulcerative colitis (UC) constitute the two most common phenotypes of inflammatory bowel disease (IBD). Ileocolonoscopy with biopsy has been considered the gold standard for the diagnosis of IBD. Differential diagnosis of CD and UC is important, as their medical and surgical treatment modalities and prognoses can be different. However, approximately 15% of patients with IBD are misdiagnosed as IBD unclassified due to the lack of diagnostic certainty of CD or UC. Recently, there has been increased recognition of the role of the therapeutic endoscopist in the field of IBD...

Inflammatory bowel diseases have an important impact upon the economic and social status due to their increasing incidence and prevalence, often affecting young people. At the moment, the therapeutic goal goes beyond the improvement of symptoms and laboratory parameters, being represented by endoscopic mucosal healing, changing the disease's natural history. Even though endoscopy is the gold standard for the assessment of mucosal healing, it is an invasive maneuver and it lacks good repeatability. These patients require frequent evaluation; therefore, interest for noninvasive techniques has risen...

Optoacoustic (photoacoustic) endoscopy has shown potential to reveal complementary contrast to optical endoscopy methods, indicating clinical relevance. However operational parameters for accurate optoacoustic endoscopy must be specified for optimal performance. Recent support from the EU Horizon 2020 program ESOTRAC to develop a next-generation optoacoustic esophageal endoscope directs the interrogation of the optimal frequency required for accurate implementation. We simulated the frequency response of the esophagus wall and then validated the simulation results with experimental measurements of pig esophagus...

BACKGROUND: Duodenal neuroendocrine neoplasms (dNENs) are rare tumors, which usually show good prognosis. The optimal management of these tumors is still far from being clearly understood because of their rarity and the poor level of knowledge about their natural history. Herein, we have reviewed the literature on dNENs to collect and analyze the current data on epidemiology, diagnosis and management of these rare tumors. METHODS: Bibliographical searches were performed in PubMed, using the following keywords: duodenal neuroendocrine neoplasm; duodenum; gastrinoma; diagnosis; therapy; guidelines...

Esophageal varices are one of the main complications of liver cirrhosis. Upper gastrointestinal endoscopy is the gold standard for the detection of esophageal varices. Many less invasive methods for screening of varices have been investigated and the most recent Baveno VI guidelines suggest that endoscopy is not necessary in patients with liver stiffness <20 kPa and platelets >150,000/μL. A critical review of the literature was performed concerning non-invasive or minimally invasive methods of screening for esophageal varices...

Intestinal ultrasonography has emerged as a cheap, non-invasive and readily accessible modality for the assessment of a number of gastroenterological diseases. Over the last decade, particularly due to the widespread use of biological agents in Inflammatory Bowel Disease (IBD), guidelines regarding management and follow-up advise more regular disease assessment and surveillance in order to guide treatment adjustments, and provide more personalised care. Given the young age of the majority of patients with IBD the availability of an alternative modality to harmful radiation or the risks of endoscopy for this indication offers an appealing advantage...

BACKGROUND: Pancreatic cysts are being diagnosed more frequently because of the increasing usage of imaging techniques. A pseudocyst with the major diameter of 10 cm is termed as a giant cyst. Asymptomatic pseudo-cysts up to 6 cm in diameter can be safely observed and monitored without intervention, but larger and symptomatic pseudocysts require intervention. CASE PRESENTATION: A 27-year-old Sri Lankan male, with history of heavy alcohol use, presented with progressive abdominal distension following an episode of acute pancreatitis...
