We present the case of a patient under study due to ascites in which a mass located on the gastric wall was observed during ultrasonography. Further studies (upper endoscopy and computed tomography) confirmed this finding. After an ultrasound-guided percutaneous biopsy, diagnosis of gastric schwannoma was made as intense S-100 expression was found. Surgery was rejected due to the bad clinical situation of the patient and because the mass was an asymptomatic benign tumor.

BACKGROUND: Palliative therapy and primarily chemoradiotherapy are the mainstream treatments in patients with locally advanced or metastatic pancreatic cancer (PC). Conventional endoscopy and endoscopic ultrasound (EUS)-guided interventional therapy has emerged as an important procedure for PC management. In this review, the progress in conventional endoscopy and EUS for PC management is discussed. SUMMARY: For local palliative therapy against PC, EUS-guided fine needle injection (FNI) could deliver different kinds of agents, such as radioactive seeds and fiducials...

Endoscopic retrograde cholangiopancreatography (ERCP) has become the mainstay of therapy for pancreatobiliary diseases. While ERCP is safe and highly effective in the general population, the procedure remains challenging or impossible in patients with surgically altered anatomy (SAA). Endoscopic ultrasound (EUS) allows transmural access to the bile or pancreatic duct (PD) prior to ductal drainage using ERCP-based techniques. Also known as endosonography-guided cholangiopancreatography (ESCP), the procedure provides multiple advantages over overtube-assisted enteroscopy ERCP or percutaneous or surgical approaches...

INTRODUCTION: High-grade vesicoureteral reflux (VUR) in infants is associated with congenital renal abnormalities, recurrent UTI, and bladder dysfunction. Endoscopic treatment (ET) is a well-established method in children with low to moderate reflux grades, but there is a lack of randomised controlled trials regarding the use of ET versus continuous antibiotic prophylaxis in infants with high-grade VUR. OBJECTIVE: This study aimed to determine whether high-grade VUR in infants can be treated with endoscopic injection and whether ET is superior to antibiotic prophylaxis in the treatment of VUR...

Early diagnosis and accurate staging of pancreatic cancer is very important to plan optimal management strategy. Endoscopy plays an important role in the diagnosis and management of pancreatic cancer. Endoscopic ultrasound imaging (EUS) is the most sensitive modality for diagnosis, especially for small pancreatic tumors; it also allows tissue acquisition for histological diagnosis. Computed tomography scanning and EUS play complementary roles in staging and are comparable in determining resectability. Endoscopic retrograde cholangiopancreatography allows tissue sampling but is limited to palliative biliary drainage in most cases...

BACKGROUND: Endoscopic ultrasound (EUS) has been routinely utilized for the locoregional staging of esophageal cancer. One important aspect of clinical staging has been to stratify patients to treatment with neoadjuvant chemoradiation or primary surgical therapy. We hypothesized that EUS may have a limited impact on clinical decision making in patients with dysphagia and obstructing esophageal masses. METHODS: This retrospective cohort study included all patients with esophageal adenocarcinoma undergoing esophageal EUS between July 2008 and September 2013...

Incidental gastric subepithelial tumor (SET) is frequently found during endoscopy. Although endoscopic ultrasonography (EUS) can provide useful information, its diagnostic accuracy varies. Most of the potentially malignant tumors observed on EUS are hypoechoic lesions. Therefore, we aimed to investigate the diagnostic accuracy of EUS for hypoechoic lesions located in the submucosa or proper muscle layer. We also evaluated various characteristics for potential associations with diagnostic accuracy.A retrospective review was conducted of the medical records of 99 patients who were diagnosed with gastric SET and who underwent EUS with pathologic confirmation between March 2008 and April 2015...

INTRODUCTION: Percutaneous nephrolithotomy (PCNL) is the preferred treatment of choice for renal calculi. PCNL has evolved remarkably since the eighties when it was first described. APPROACH: Approach might be by either supine or prone and the access is made with the help of either fluoroscopy or ultrasound. Recently endoscopy guided puncture has also been described. MINIATURIZATION: Traditionally the tract size for PCNL used to be 30Fr. Even though the stone clearance rate was good there were complications such as bleeding With the advent of excellent optics and advances in stone fragmentation the tract size has reduced to a great extent which has reduced the complications without compromising the stone clearance...

Organ models are used for planning and simulation of operations, developing new surgical instruments, and training purposes. There is a substantial demand for in vitro organ phantoms, especially in urological surgery. Animal models and existing simulator systems poorly mimic the detailed morphology and the physical properties of human organs. In this paper, we report a novel fabrication process to make a human kidney phantom with realistic anatomical structures and physical properties. The detailed anatomical structure was directly acquired from high resolution CT data sets of human cadaveric kidneys...

This case report includes different diagnostic imaging methods for localization of textile foreign bodies in reptiles and shows the limitations and advantages of these methods. A six-year-old, male, green iguana was presented to our clinic after ingesting a sock 5 days earlier. Ultrasound, contrast x-ray, computed tomography and endoscopy were used to locate the foreign body before surgery. Attempts to remove the sock endoscopically failed. The sock was surgically removed via celiotomy and enterotomy.

Plexiform angiomyxoid myofibroblastic tumor (PAMT) is a rare benign mesenchymal tumor of stomach. Rarity of this kind of tumors and scarce review articles may cause underrecognition of this entity and pose a real diagnostic challenge to gastroenterologists, pathologists and surgeons when encountering such patients and differentiating PAMT from other gastric intramural tumors. We report a case of 28-year-old woman, who presented with epigastric pain after meals, iron-deficiency anaemia and weight loss. Upper gastrointestinal endoscopy revealed submucosal tumor-like elevated lesion in the anterior wall of the antrum with intact overlying mucosa...

Isolated gastric cavernous haemangioma is extremely rare in the stomach. Historically, endoscopy, computed tomography and MRI had been used to diagnose gastric cavernous haemangioma. Biopsy, is not an option due to its vascular nature and submucosal location. We report an isolated gastric cavernous haemangioma that was diagnosed by end-oscopic ultrasound in a 25-year-old male and treated by laparotomy. The final diagnosis of cavernous haemagioma was confirmed by post-operative pathology. There was no recurrence during 3-month follow-up period...

Most esophageal lipomas are discovered incidentally and are small and asymptomatic. However, large (>4 cm) lipomas may cause various symptoms, including dysphagia, regurgitation, or epigastric discomfort. We present a 45-year-old woman with intermittent sudden choking and globus pharyngeus. Upper gastrointestinal endoscopy and endoscopic ultrasound revealed an approximately 10.0×1.5 cm pedunculated subepithelial tumor in the upper esophagus, identified as the cause of her symptoms. A thoracic computed tomography scan revealed a fat attenuated longitudinal mass along the upper esophagus, suggestive of a lipoma...

A variable spectrum of urogenital malformations exists in girls with congenital adrenal hyperplasia (CAH). The vagina may enter the urethra at a variable level, and relations to the sphincter complex vary accordingly. Furthermore, an enlarged clitoris and variations in the bladder sphincter anatomy can be found. Endoscopy, genitography or magnetic resonance imaging (MRI) are commonly used for the assessment of these anomalies, and to provide information for counselling and treatment. When surgery is planned, introitoplasty cosmetical reduction of the clitoris and labioplasty are discussed with the families; introitoplasty is the most demanding aspect...

A 60-year-old male was admitted with acute abdominal pain and fever. Computed tomography (CT) of the abdomen revealed free air. Diagnostic laparoscopy showed a toothpick perforating the ventricle, and the toothpick was removed successfully. This condition is severe with a reported mortality of 9.6%. A practical guideline based on 136 cases was presented in 2014. Endoscopy was found to be superior to CT in identifying toothpicks as well as offering therapeutic intervention, rendering endoscopy the first choice in diagnostic and treatment...

Esophageal squamous cell carcinoma (ESCC) is the commonest primary malignant esophageal tumor, which typically presents as endoscopically visible surface mucosal ulcerations, irregularities, or polyploidal masses. We here report a rare case of primary ESCC with completely intramural growth under a normal looking intact nondysplastic surface squamous epithelium disguising as a submucosal tumor. Upper gastrointestinal endoscopy-guided mucosal biopsy was negative for malignancy. Endoscopic ultrasound (EUS) revealed a heteroechoic solid mass originating from the muscularis propria of the distal esophagus...
