The endoscopic approach to pancreatobiliary diseases in postoperative patients had been difficult (1). Percutaneous or surgical interventions were applied as the first line policy. However, using double balloon endoscopes (DBE), especially the short-type DBE, radically made it practical and safe (2, 3). In this study, endoscopic technical tips using the newly developed short-type DBE (EI-580 BT; FUJIFILM Co, Tokyo, Japan) for stone-extraction via papilla for common bile duct stones in patients with Roux-en Y reconstruction post gastrectomy will be introduced...

Ambient ionization techniques are typically used to analyze samples in their native states with minimal or no sample pretreatment prior to mass spectrometric (MS) analysis. Desorption electrospray ionization (DESI) and direct analysis in real time (DART) were systematically investigated in this work for direct solid analysis of depolymerized lignin samples, with the goal of rapidly fingerprinting these samples, to efficiently characterize the subunits of this renewable energy source. High resolution MS was required for enhanced selectivity in this study due to the inherent structural complexity of lignin...

The potential of compound-specific stable isotope analysis (CSIA) to characterize biotransformation of brominated organic compounds (BOCs) was assessed and compared to chlorinated analogues. Sulfurospirillum multivorans and Desulfitobacterium hafniense PCE-S catalyzed the dehalogenation of tribromoethene (TBE) to either vinyl bromide (VB) or ethene, respectively. Significantly lower isotope fractionation was observed for TBE dehalogenation by S. multivorans (εC = -1.3 ± 0.2‰) compared to D. hafniense (εC = -7...

Capsule endoscopy (CE) and double-balloon endoscopy (DBE) have revolutionized the diagnosis and treatment of obscure gastrointestinal bleeding (OGIB). Although CE and DBE provide access to the small bowel and OGIB can be effectively treated by the identification of specific bleeding lesions, some patients experience rebleeding after small bowel investigation. There are no definite algorithms to determine the best follow-up period for patients with OGIB. The purpose of this study was to investigate the long-term outcomes and risk factors for rebleeding and to develop a follow-up strategy for patients with overt OGIB...

Double balloon enteroscopy (DBE) is an endoscopic technique broadly used to diagnose and treat small bowel diseases. Among the associated complications of the oral DBE, post-procedure pancreatitis has taken the most attention due to its gravity and the thought that it might be associated to the technique itself and anatomical features of the pancreas. However, as the etiology has not been clarified yet, this paper aims to review the published literature and adds new results from a porcine animal model. Biochemical markers, histological sections and the vascular perfusion of the pancreas were monitored in the pig during DBE practice...

BACKGROUND: Small bowel capsule endoscopy (SBCE) is the recommended first-line procedure for obscure gastrointestinal bleeding (OGIB). However, a method for predicting the necessity of subsequent double-balloon endoscopy (DBE) has not been established. AIMS: We aimed to develop a new scoring system that predicts the necessity of DBE in OGIB. METHODS: A retrospective study was performed in 330 patients who underwent SBCE for OGIB at Nagoya University Hospital...

Hookworm infections are widely prevalent in tropical and subtropical areas, especially in low income regions. In the body, hookworms parasitize the proximal small intestine, leading to chronic intestinal hemorrhage and iron deficiency anemia. Occasionally, hookworms can cause overt gastrointestinal bleeding, but this is often ignored in heavily burdened individuals from endemic infectious areas. A total of 424 patients with overt obscure gastrointestinal bleeding were diagnosed by numerous blood tests or stool examinations as well as esophagogastroduodenoscopy, colonoscopy, capsule endoscopy or double-balloon enteroscopy...

BACKGROUND: Patients with Crohn's disease (CD) with small bowel strictures are at risk of surgery. Double-balloon enteroscopy (DBE) can evaluate the status of the small intestine, and retrograde contrast through the scope enables the surgeon to obtain information beyond the reach of the scope. This study aimed to examine whether a retrograde contrast study through DBE could be used as a predictor of subsequent surgery in patients with CD with small intestinal strictures. METHODS: The findings of DBE with retrograde contrast in 48 patients CD with small bowel strictures were examined...

The toxicological effects from all components in oil sands process-affected water (OSPW) are not known. Alternatively, monitoring the variations and abundance of different classes and compounds after treatments might be a useful approach in OSPW remediation. In this study, the variations in the compositions of classical and heteroatomic naphthenic acids (NAs) after treatment using advanced oxidation processes (AOPs), mainly ozone and peroxone, and two different mass spectrometry methods; ultra-performance liquid chromatography time-of-flight (UPLC-TOFMS) and Fourier transform ion cyclotron resonance (FTICR-MS), were examined...

A 75-year-old man presented with abdominal distension, hypoproteinemia, ascites and a 35-mm mass in the small bowel mesentery. Laparotomy was performed, and he was diagnosed with sclerosing mesenteritis. His clinical condition improved, with computed tomography (CT) showing tumor shrinkage and decreasing ascites after administration of prednisolone; however, on drug withdrawal, abdominal fullness recurred and CT revealed an enlarging tumor and increasing ascites. Capsule endoscopy (CE) and double-balloon enteroscopy (DBE) were performed to further investigate hypoalbuminemia, which revealed white villi, white nodules, white debris, and mucosal edema in the jejunum...
