Background and study aims: Overall, 5 % to 15 % of patients undergoing cholecystectomy for cholelithiasis have concomitant bile duct stones, and the incidence of choledocholithiasis increases with age. There is no clear consensus on the best therapeutic approach (endoscopic versus surgical). Patients and methods: A prospective randomized controlled clinical trial was performed to compare three treatment options for patients with choledocholithiasis at the National Center for Minimally Invasive Surgery in Havana, Cuba from November 2007 to November 2011...

We report a case series of five patients with pancreatic acinar cell carcinoma who received surgical treatment and compared the preoperative contrast-enhanced endoscopic ultrasound (EUS) and EUS elastography patterns with the surgical specimens. The contrast-enhanced EUS indicated vascular tumors with gradual enhancement in four patients and a hypovascular tumor in one patient. The elastography indicated an elastic score of 3 (hard lesion with softer border) in two patients and a score of 5 (hard lesion, which included the surrounding area) in two patients...

: Background and study aims: Colonoscopy can cause anxiety and discomfort in patients. Sedation and analgesia as premedication can lead to complications in the elderly and those with comorbidities. This has led to an interest in the use of audio-visual distraction during the colonoscopy. We compared the effects of audio (AD) versus visual distraction (VD) in reducing discomfort and the need for sedation during colonoscopy. Patients and methods: Consecutive patients undergoing colonoscopy were randomized into three groups: one group was allowed to listen to the music of their choice (AD), the second group was allowed to watch a movie of their choice (VD), and the third group was not allowed either distraction during colonoscopy and acted as a control (C)...

: Background and study aims: The aim of this study was to investigate the capability of magnifying endoscopy with narrow-band imaging (ME-NBI) to discriminate between early carcinomas (EC) and low grade adenomas (LGA) in gastric superficial elevated epithelial neoplasias. Patients and methods: We investigated 100 consecutive cases of gastric superficial elevated epithelial neoplasias that were removed using endoscopic submucosal dissection. The pathological diagnostic criteria were based on the revised Vienna classification; category 4 (mucosal high grade neoplasia) and category 5 (submucosal invasion by carcinoma) lesions were diagnosed as EC, whereas category 3 (mucosal low grade neoplasia) lesions were diagnosed as LGA...

Background and aims: Endoscopic ultrasound (EUS) guided right adrenal gland (RAG) evaluation is frequently unsuccessful and, when feasible, requires a cumbersome maneuver through the duodenum. In our experience, the use of a recent ultrasound platform has enabled transgastric detection of the RAG with a simple maneuver. The aim of this study was to determine the RAG transgastric EUS detection rate and identify predictive factors for failure. Methods: Consecutive patients referred to EUS in a single center were prospectively included over a 6-month period...

Background and study aims: Colitis-associated cancer/dysplasia (CC/D) can affect the life expectancy of patients with ulcerative colitis (UC). Although the utility of magnifying chromocolonoscopy has been shown, the use of optical magnification with narrow band imaging (NBI) for distinguishing CC/D from non-neoplastic lesions in patients with UC has not been reported. We evaluated whether endoscopic findings are distinguishing and thus assessed the clinical usefulness of NBI magnification for differentiating UC-associated lesions...

Background and study aims: Endoscopic retrograde cholangiopancreatography-related infections are of increasing global concern due to the emergence of multidrug-resistant bacteria such as carbapenem-resistant enterobacteriaceae (CRE), with bacterial biofilm production postulated as one cause of persistent infection from such virulent organisms. Because N-acetylcysteine (NAC) has been shown to possess antibacterial and biofilm-disruption properties, we aimed to evaluate if NAC would demonstrate clinical utility in reducing the colony forming units (CFU) at the elevator end of a duodenoscope, one of the hardest areas to clean...

Nam Q Nguyen, Jenna Burgess, Tamara L Debreceni, Leanne Toscano
Background and study aims: Colonoscopy with portal inhaled methoxyflurane (Penthrox) is highly feasible with low sedation risk and allows earlier discharge. It is unclear if subjects can return to highly skilled psychomotor skill task shortly after Penthrox assisted colonoscopy. We evaluated the psychomotor and cognitive effects of 15-minute inhalation of Penthrox in adults. Patients and methods: Sixty healthy volunteers (18 to 80 years) were studied on 2 occasions with either Penthrox or placebo in a randomized, double-blind fashion...

Background and study aims: We previously reported our discovery of a white opaque substance (WOS) that is opaque to endoscopic light inside the epithelium while using magnifying endoscopy (ME) to examine gastric epithelial neoplasia. Histopathologic analysis revealed that the WOS comprises minute lipid droplets (LDs) accumulated within the neoplastic epithelium. In addition, the WOS was found in colorectal epithelial neoplasia, although it was unclear whether this WOS corresponded to an accumulation of LDs, as in the stomach...

Background/aims: The optimal intervention for Boerhaave perforation has not been determined. Options include surgical repair with/without a pedicled muscle flap, T tube placement, esophageal resection or diversion, or an endoscopic approach. All management strategies require adequate drainage and nutritional support. Our aim was to evaluate outcomes following Boerhaave perforation treated with surgery, endoscopic therapy, or both. Patients and methods: We performed a 10-year review of our prospectively maintained databases of adult patients with Boerhaave perforations...

Background and study aims: Gastric neuroendocrine tumors (NETs) are rare lesions that develop from neuroendocrine cells. NETs are classified into 3 types based on the rate of mitosis and Ki-67 labeling index; the NET G1 type is synonymously referred to as carcinoid. Gastric NETs are usually discovered as submucosal tumors during upper gastrointestinal endoscopic examination. This study reports a rare case of pedunculated gastric NET. The lesion was found as a result of gastroendoscopy. The gastric lesion was a pedunculated polyp with a reddish head...

: Background and aims: Endoscopic ultrasound (EUS)-guided needle-based Confocal Laser Endomicroscopy (nCLE) characteristics of pancreatic cystic lesions (PCLs) have been identified in studies where the gold standard surgical histopathology was available in a minority of patients. There are diverging reports of interobserver agreement (IOA) and paucity of intraobserver reliability (IOR). Thus, we sought to validate current EUS-nCLE criteria of PCLs in a larger consecutive series of surgical patients...
