BACKGROUND: Gallstone disease is common after bariatric surgery, and patients with bile duct stones in this cohort can be difficult to treat, due to the altered anatomy. This review aims to analyse the various management options available for choledocholithiasis in post-bariatric surgery patients. METHODS: A literature search of PubMed, Medline and Cochrane library databases was carried out for studies on this subject, between January 1970 and March 2017. After initial screening and further full text review, suitable studies were identified after applying the inclusion criteria...

Introduction:  EUS-guided cystoenterostomy (EUCE), a technique used for the drainage of pancreatic pseudocysts and peri-enteric collections, requires specific skills for which dedicated models are needed. Based on a compact EASIE model (Erlangen Active Simulator for Interventional Endoscopy), we developed two ex vivo porcine models of retrogastric cysts and evaluated learning performance within the frame of a structured training program. Material and methods:  The first model was made of porcine colon (i...

Carpal tunnel syndrome is the most common nerve entrapment syndrome. The majority of cases are due to compression or irritation of the median nerve in the carpal canal. It is diagnosed clinically, often being confirmed by an electromyogram, while ultrasonography criteria have become increasingly useful for the diagnosis. Ultrasonography is better tolerated, less expensive, yet just as effective as other diagnostic methods. It provides a good indication of the severity of the condition and it allows anatomical variants to be discerned...

Pancreaticojejunostomy stricture (PJS) is a late complication of pancreaticoduodenectomy. The endoscopic treatment of PJS is very challenging due to the difficulty of locating the small anastomotic site and passing the stricture using a guidewire. We herein report two cases of severe PJS. These patients could not be treated using only double-balloon endoscopy or endoscopic ultrasound-guided puncture of the main pancreatic duct because of severe stenosis at the anastomotic site. However, we could treat them by the rendezvous technique using the rigid part of the guidewire to penetrate PJS...

Endoscopy enables minimally invasive procedures in many medical fields, such as urology. However, current endoscopes are normally cable-driven, which limits their dexterity and makes them hard to miniaturize. Indeed current urological endoscopes have an outer diameter of about 3 mm and still only possess one bending degree of freedom. In this paper, we report a novel wireless actuation mechanism that increases the dexterity and that permits the miniaturization of a urological endoscope. The novel actuator consists of thin active surfaces that can be readily attached to any device and are wirelessly powered by ultrasound...

Introduction: The growing incidence of gastrointestinal diseases forces to improve both imaging techniques and the identification of the population with a greater risk of a disease. Identification of lesions located inside the wall of intestinal tract or in close proximity often was not possible using endoscopy or computed tomography. Aim: The study was a retrospective evaluation of the occurrence of submucosal lesions (SML) and thickened wall (TW) of the upper gastrointestinal tract (UGIT) depending on age and sex...

Background: American Society of Gastrointestinal Endoscopy (ASGE) criteria is widely used to predict probability of choledocholithiasis among patients with symptomatic gallstone disease but does not take sex into consideration. Methods: The cohort study included patients who underwent either endoscopic retrograde cholangiopancreatography or intraoperative cholangiography for suspected choledocholithiasis at our medical center. Clinical, laboratory and radiological data were collected for each patient and used to stratify them based on the ASGE risk criteria for choledocholithiasis...

BACKGROUND: Infected necrotising pancreatitis is a potentially lethal disease and an indication for invasive intervention. The surgical step-up approach is the standard treatment. A promising alternative is the endoscopic step-up approach. We compared both approaches to see whether the endoscopic step-up approach was superior to the surgical step-up approach in terms of clinical and economic outcomes. METHODS: In this multicentre, randomised, superiority trial, we recruited adult patients with infected necrotising pancreatitis and an indication for invasive intervention from 19 hospitals in the Netherlands...

In recent years, various technological developments markedly improved imaging of mucosal inflammation in patients with inflammatory bowel diseases. Although technological developments such as high-definition-, chromo-, and autofluorescence-endoscopy led to a more precise and detailed assessment of mucosal inflammation during wide-field endoscopy, probe-based and stationary confocal laser microscopy enabled in vivo real-time microscopic imaging of mucosal surfaces within the gastrointestinal tract. Through the use of fluorochromes with specificity against a defined molecular target combined with endoscopic techniques that allow ultrastructural resolution, molecular imaging enables in vivo visualization of single molecules or receptors during endoscopy...

Rapunzel syndrome is a rare form of gastric trichobezoar. A 4-year-old girl presented with generalised oedema and an epigastric mass. Her family was of a relatively low socio-economic background. There was microcytic hypochromic anaemia, hypoalbuminaemia and an elevated α1-antitrypsin clearance. Abdominal ultrasound and non-contrast computed tomography demonstrated a heterogeneous mass related to the stomach. Upper gastro-intestinal tract endoscopy failed to remove it. Surgical laparotomy was undertaken through a single anterior gastrotomy incision and a large mass was extracted which was a cast of the duodenum and stomach and had a tail of approximately 60 cm in length which extended to the jejunum...

Pancreatic cancers are usually detected at an advanced stage and have poor prognosis. About one fifth of these arise from pancreatic cystic lesions. Yet not all lesions are precancerous, and imaging tools lack adequate accuracy for distinguishing precancerous from benign cysts. Therefore, decisions on surgical resection usually rely on endoscopic ultrasound-guided fine needle aspiration (EUS-FNA). Unfortunately, cyst fluid often contains few cells, and fluid chemical analysis lacks accuracy, resulting in dire consequences, including unnecessary pancreatic surgery for benign cysts and the development of cancer...

AIM: The aim of this study is to evaluate the information given by contrast-enhanced computer tomography (CECT) and ultrasound endoscopy (EUS) regarding vascular involvement of cephalo-pancreatic cancer, data compared with intraoperative findings. MATERIAL AND METHODS: We choose to analyze the most often interested vessels by tumor development, such as superior mesenteric artery (SMA), superior mesenteric vein (SMV) and portal vein (PV). The patients included in the study (n=425) had a cephalo-pancreatic tumor diagnosed in our Institute and a positive histology for pancreatic adenocarcinoma...

Ultrasound is becoming a valuable diagnostic tool in the armamentarium of thoracic surgeons. We report its use to follow stent placement in the laryngotracheal position for management of life-threatening neoplastic obstruction. For this purpose, a 15-MHz linear probe was placed in the midline at the level of the cricoid cartilage. Ultrasound performed daily at bedside showed normal movement of vocal folds and no stent dislocation. This strategy may be an alternative to computed tomography scan or endoscopy to follow stent placement in extrathoracic airways...

Anaphylaxis during anesthesia is an unpredictable, severe, and rare reaction. It has an incidence of 1/10 000 to 1/20 000 surgeries. In most series, the responsible drugs include neuromuscular blocking agents, latex, or antibiotics. The frequency and etiology of systemic allergic reactions in other medical procedures are largely unknown. The identification of responsible drugs of anaphylaxis is a complex task, requiring testing of all medications and substances used during surgery. We describe our experience in a retrospective study of 15 patients...

Gastric glomus tumors are extremely rare, constituting approximately 1% of gastric mesenchymal tumors. We report the case of a 45-year-old female patient in whom upper gastrointestinal endoscopy revealed a 3-cm submucosal tumor with a bridging fold in the posterior wall of the antrum of the stomach. Contrast-enhanced computed tomography revealed the tumor to be hypervascular in the arterial phase and exhibit continuous enhancement in the post-venous phase. Dynamic contrast-enhanced magnetic resonance imaging showed that the tumor was hypervascular in the early phase and persistently enhanced in the late phase...

Gastrointestinal stromal tumors (GISTs) are rare soft tissue tumors. Despite their rarity, these tumors are the most common gastrointestinal (GI) mesenchymal tumors. They can involve various parts of the gastrointestinal tract. GISTs growth can be intramural, intraluminal or exophytic. Symptoms are usually related to GI bleeding and to adjacent organ compression by the tumor. Endoscopy can suggest the diagnosis, but tissue sampling is required for the diagnosis. Herein, we present a unique case of GIST where the patient had negative endoscopic findings despite the large size of the tumor, thus abdominal computed tomography scan and endoscopic ultrasound was required to make the diagnosis...

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...
