Endoscopic ultrasound has become an essential tool in modern gastroenterology and abdominal surgery. Compared with all other endoscopic methods, it has the most potential for innovation and its future looks bright. Thus, we compiled this summary of established and novel applications of endoscopic ultrasound methods to inform the reader about what is already possible and where future developments will lead in improving patient care further. This review is structured in four parts. The first section reports on developments in diagnostic endoscopic ultrasound, the second looks at semi-invasive endoscopic ultrasound, and the third discusses advances in therapeutic endoscopic ultrasound...

The majority of patients with neuropathic incontinence and other pelvic floor conditions associated with straining at stool have damage to the pudendal nerves distal to the ischial spine. Sacral nerve stimulation appears to be a promising innovation and has been widely adopted and currently considered the standard of care for adults with moderate to severe fecal incontinence and following failed sphincter repair. From a decision-to-treat perspective, the short-term efficacy is good (70%-80%), but the long-term efficacy of sacral nerve stimulation is around 50%...

BACKGROUND: Catheter-based lysis with recombinant tissue plasminogen activator (rtPA) is a well-established therapy for spontaneous intracerebral hemorrhage (ICH). The effectiveness of this therapy can be increased with ultrasound, but the optimal conditions are not yet clearly established. Using a novel in vitro system of blood clots previously developed by our group, we investigated various parameters of intralesional sonothrombolysis using an endosonography catheter in combination with rtPA...

An 11-year-old morbidly obese boy was diagnosed with pancreatic pseudocyst. Following fine needle aspiration, the cyst recurred in 1-month follow-up. Therefore, endoscopic drainage and cystoduodenostomy was performed following endosonography. Control ultrasonography (USG) revealed a completely shrunken cyst. During the 3 years of follow-up, the patient was asymptomatic with no evidence of cyst on computerized tomography scans. Endoscopic drainage and cystoduodenostomy is a minimally invasive, effective, and safe approach in the management of pancreatic pseudocysts in children...

INTRODUCTION AND OBJECTIVES: Endosonography has become standard of care in the diagnostic work-up of mediastinal lymphadenopathy and peribronchial lung lesions, but its success rate in some specific settings/conditions may be hampered by limited needle flexibility and size. We report on our initial experience with the 19G Flex needle, characterized by larger size and greater flexibility as compared with the currently available cytology needles. METHODS: Retrospective review of prospectively collected data on the first 13 consecutive patients submitted to endosonography with the 19G Flex needle...

BACKGROUND: The success of transanal endoscopic microsurgery (TEM) for early rectal cancer depends on proper indications and strict patient selection. When unfavorable pathologic features are identified after TEM operation, total mesorectal excision is recommended to minimize the risk of recurrence. In this study, data were collected in a retrospective series of patients to determine the results of laparoscopic reoperation after TEM. METHODS: All patients underwent an accurate rectal-digital examination and clinical tumor staging by transanal endosonography, CT, and/or MRI...

There was not available data about the overlap between functional dyspepsia (FD) and pancreatic diseases. We aimed to determine whether epigastric pain syndrome (EPS) accompanying with pancreatic enzyme abnormalities were associated with early chronic pancreatitis proposed by Japan Pancreas Society (JPS) using endosonography. We enrolled 99 consecutive patients presenting with typical symptoms of FD, including patients with postprandial distress syndrome (PDS) (n = 59), EPS with pancreatic enzyme abnormalities (n = 41) and EPS without pancreatic enzyme abnormalities (n = 42) based on Rome III criteria...

Therapeutic endosonography (EUS) may play an important role in the management of cancers. EUS-guided fiducial placement has a high success rate and can aid in stereotactic radiotherapy. EUS-guided tumor ablation therapies can help in palliation of locally advanced tumors. EUS-guided antitumor injection seems to be feasible and safe in animals; initial human studies suffer from small sample size and lack of controls. Randomized, controlled trials have not shown benefit over conventional therapy. EUS celiac plexus neurolysis has gained popularity and is performed by interventional endosonographers...

Superparamagnetic iron oxide nanoparticles (SPION) may be used for local tumor treatment by coupling them to a drug and accumulating them locally with magnetic field traps, that is, a combination of permanent magnets and coils. Thereafter, an alternating magnetic field generates heat which may be used to release the thermosensitively bound drug and for hyperthermia. Until today, only superficial tumors can be treated with this method. Our aim was to transfer this method into an endoscopic setting to also reach the majority of tumors located inside the body...

The objective of this study is the feasibility of sequential endoscopic and endosonographic measurement of locoregional tumor load for the prediction of tumor recurrence in patients after neoadjuvant or definitive chemoradiotherapy, treated in curative intent for locally advanced esophageal carcinoma. In 67 patients with esophageal cancer, serial endoscopic ultrasound was performed before and after neoadjuvant (25) or definitive (42) chemoradiotherapy. Rate of complete endoscopic and endosonographic tumor response, reduction in tumor length or circumferential tumorous extension, maximal tumor thickness, lymph node size, and endosonographic uT- and uN-stage shift was measured...

Heterotopic pancreas in the stomach is usually asymptomatic and benign. Here, we presented a rare case of an early gastric cancer overlying a heterotopic pancreas. A 48-year-old woman underwent esophagogastroduodenoscopy, which revealed a subepithelial mass measuring 2.0×1.5 cm on the gastric antrum with a 1-cm erosive erythematous discoloration on the surface. A biopsy specimen showed moderately differentiated tubular adenocarcinoma. Endosonography showed a heterogeneous hypoechoic mass measuring 1.3×0.6 cm, with indistinct margins in the second and third layers of the gastric wall; anechoic tubular structures within the mass were suggestive of heterotopic pancreas...

The incidence of cystic pancreatic lesions is steadily increasing due to the technical advances in imaging. Within the group of cystic pancreatic lesions intraductal papillary mucinous neoplasms (IPMNs) depict an important entity. Due to a possible progression to malignancy the clinical strategy has to be well chosen. For primary diagnostic work-up imaging by magnetic resonance imaging (MRI) with MR cholangiopancreatography (MRCP) and computed tomography (CT) scanning is recommended. Additional information can be gained by endosonography and a biopsy of the cystic lesion, allowing analysis of biomarkers, such as GNAS and KRAS mutation as wells as NLR...

A 46-year-old woman presented with acute abdominal pain in the right upper quadrant. Esophagogastroduodenoscopy revealed a duodenal stenosis within the horizontal part of the duodenum. Based on the findings of abdominal computed tomography (CT), endosonography, Doppler duplex sonography and angiography, the diagnosis of an aneurysm of a branch of the inferior pancreaticoduodenal artery was established. This arterial branch was part of a collateral circulation between the superior mesenteric artery and the proper hepatic artery caused by obturation of the celiac artery...

INTRODUCTION: Endosonography guided celiac plexus neurolysis is efficacious in the management of severe pain due to advanced pancreatic cancer. Although endoscopic ultrasound (EUS) guided celiac neurolysis (CN) is mostly a safer procedure than the percutaneous posterior approach, severe complications such as paraplegia have been reported. CASE REPORT: We describe a patient with advanced adenocarcinoma of the pancreas and severe pain who developed irreversible paraplegia after EUS guided CN...

BACKGROUND AND STUDY AIMS: Intra-abdominal and mediastinal lymphadenopathy are often difficult to diagnose, particularly in the absence of a primary lesion. Endosonography (EUS)-guided fine-needle aspiration and cytology (FNAC) has provided an easy and safe access to these lymph nodes, sparing the use of invasive and costly interventions. The main aim of this study is to assess the specificity, sensitivity, and predictive value of EUS-guided FNAC in the diagnosis of benign and malignant lymph nodes...

Although lymphoepithelial cysts (LECs) of the pancreas are benign lesions, most of them have been treated with surgical resection due to diagnostic difficulty. We report a 66-year-old woman diagnosed with pancreatic LECs. Abdominal ultrasound revealed two masses in the pancreas, which were not visible on the abdominal computed tomography. In an abdominal magnetic resonance imaging, pancreas lesions showed solid tumors, which revealed a low signal intensity on T1-, moderate high signal intensity on T2 weighted images, and homogeneous delayed enhancement in the portal venous phase...

Malformations of the rectum and urinary tract frequently coexist, and the prevalence of urogenital defects in patients with a rectal defect ranges from 20 to 54%. In most patients, anorectal malformations are diagnosed and treated surgically in early childhood. In this report, we present a case of a 52-year-old male with a history of urological operations in infancy due to a congenital urethral malformation and multiple recurrent episodes of perineal abscesses with urinary retention. Anorectal endosonography and magnetic resonance imaging revealed the presence of a large cystic lesion adjacent to the rectal wall which became smaller at the level of the puborectalis...

Endoscopic ultrasound (EUS) is considered a valuable diagnostic tool during the workup of malignant gastric lesions, including primary gastric lymphomas (PGL). Although endoscopy combined with multiple biopsies remains essential in the establishment of PGL diagnosis, EUS utilization in locoregional disease staging has been well documented in the literature. Data also support the possible role of EUS in prediction of response to first-line treatment, that is, Helicobacter pylori eradication. However, its application in the posttreatment setting remains problematic, since concordance rates between endosonography and histology findings during follow-up seem to vary substantially...
