BACKGROUND: Gastrointestinal (GI) tract perforation during endoscopy is a rare but severe complication. The aim of this study was to determine predictors of morbidity and mortality after iatrogenic endoscopic perforation. MATERIALS AND METHODS: All cases with iatrogenic endoscopic perforation receiving surgery at a tertiary referral center in a 15-year period (2000-2015) were retrospectively analyzed. Demographics, type of endoscopy, site of perforation, operative procedure, morbidity and mortality were analyzed...

Serotonin (5-hydroxytryptamine, 5-HT) is a multi-functional bioamine with important signaling roles in a range of physiological pathways. Almost all the 5-HT in our body is synthesized in specialized enteroendocrine cells within the gastrointestinal (GI) mucosa called enterochromaffin (EC) cells. These cells provide all our circulating 5-HT. While we have long appreciated the important roles of 5-HT within the gut including the modulation of GI motility, there is recently emerging evidence of the physiological and clinical significance of gut-derived 5-HT outside of the gut...

G-protein coupled receptors may have a role in mediating the antiepileptogenic effect of low-frequency stimulation (LFS) on kindling acquisition. This effect is accompanied by changes at the intracellular level of cAMP. In the present study, the effect of rolipram as a phosphodiesterase inhibitor on the antiepileptogenic effect of LFS was investigated. Meanwhile, the expression of αs- and αi-subunit of G proteins and regulators of G-protein signaling (RGS) proteins following LFS application was measured. Male Wistar rats were kindled by perforant path stimulation in a semi-rapid kindling manner (12 stimulations per day) during a period of 6days...

Fresh vegetables and their ready-to-eat (RTE) salads have become increasingly recognized as potential vehicles for foodborne diseases. The EU Reg. 1441/2007 establishes microbiological criteria for bacterial pathogens for products placed on the market during their shelf-life (i.e. Salmonella spp., Listeria monocytogenes) for pre-cut fruits and vegetables (RTE) whilst it does not address the problem of contamination by enteric viruses. In this study we investigated the contamination by hepatitis A virus (HAV), hepatitis E virus (HEV) and norovirus (NoV) in 911 ready-to-eat vegetable samples taken from products at retail in Apulia and in Lombardia...

BACKGROUND: Percutaneous coronary intervention (PCI) has been the main therapy in acute coronary syndromes, and early antithrombotic agents as well as 1-year dual antiplatelet therapy are required for adjuvant therapy. However, the development of post-PCI gastrointestinal (GI) bleeding may increase all-cause mortality. We compared the characteristics and outcomes of patients with GI bleeding within 1 year after PCI to those who did not develop bleeding. METHODS: A retrospective cohort study was conducted using data from 384 PCI procedures performed between January 2011 and December 2013 at our hospital...

REVIEW
Bita Geramizadeh, David A Owen
Endoscopic mucosal resection (EMR) is a non-invasive alternative to surgery that is now frequently used for resection of early lesions in both upper and lower parts of the gastrointestinal (GI) tract. One of the main advantages of these techniques is providing tissue for histopathological examination. Pathological examination of endoscopically resected specimens of GI tract is a crucial component of these procedures and is useful for prediction of both the risk of metastasis and lymph node involvement. As the first step, it is very important for the pathologist to handle the EMR gross specimen in the correct way: it should be oriented, and then the margins should be labeled and inked accurately before fixation...

Objectives. Endoscopic resection (ER) is commonly performed to treat gastric epithelial neoplasms and subepithelial tumors. The aim of this study was to predict the risk factors for surgery after ER-induced perforation. Methods. We retrospectively reviewed the data on patients who received gastric endoscopic submucosal dissection (ESD) or endoscopic mucosal resection (EMR) between January 2010 and March 2015. Patients who were confirmed to have perforation were classified into surgery and nonsurgery groups...

BACKGROUND: Low circulating levels of sex hormone-binding globulin (SHBG) have been shown to be a direct and strong risk factor for type 2 diabetes, cardiovascular diseases, and hormone-dependent cancers, although the relation between various aspects of dietary carbohydrates and SHBG levels remains unexplored in population studies. METHODS: Among postmenopausal women with available SHBG measurements at baseline (n = 11,159) in the Women's Health Initiative, we conducted a comprehensive assessment of total dietary carbohydrates, glycemic load (GL), glycemic index (GI), fiber, sugar, and various carbohydrate-abundant foods in relation to circulating SHBG using multiple linear regressions adjusting for potential covariates...

INTRODUCTION: One anastomosis gastric bypass (OAGB) demonstrated results similar to traditional Roux-en-Y procedures [1-3], in terms of weight loss and resolution of obesity-related comorbidities. The main controversy regarding OAGB is the concern for an association between biliary alkaline gastritis and esophageal or gastric cancer raised by some studies [4]. METHODS: We present the case of a 51-year-old woman with a BMI of 41 kg/m2 who underwent a laparoscopic OAGB in 2014...

Rintaro Hashimoto, Dai Hirasawa
Use of endoscopic submucosal dissection (ESD) technique has been widespread. However, ESD of lesions in the duodenum is technically more challenging than ESD in other parts of the GI tract because it is difficult to keep the submucosal layer lifted. Therefore, the procedure is associated with severe complications, such as delayed bleeding and perforation. [1] We present a case of duodenal ESD in which traction method was used with an S-O clip (Zeon Medical Co., Ltd., Tokyo, Japan) (Figure 1) [2] to visualize the submucosal layer clearly...

REVIEW
Lee M Kaplan
Bariatric surgical procedures, including gastric bypass, vertical sleeve gastrectomy, and biliopancreatic diversion, are the most effective and durable treatments for obesity. In addition, These operations induce metabolic changes that provide weight-independent improvement in type 2 diabetes, fatty liver disease and other metabolic disorders. Initially thought to work by mechanical restriction of food intake or malabsorption of ingested nutrients, these procedures are now known to work through complex changes in neuroendocrine and immune signals emanating from the gut, including peptide hormones, bile acids, vagal nerve activity, and metabolites generated by the gut microbiota, all collaborating to reregulate appetite, food preference, and energy expenditure...

Most research into cognitive biases has used Western samples, despite potential East-West socio-cultural differences. One reason is the lack of appropriate measures for non-Westerners. This study is about cross-linguistic equivalence which needs to be established before assessing cross-cultural differences in future research. We developed parallel Mandarin and English measures of interpretation bias and attention bias using back-translation and decentering procedures. We assessed task equivalence by administering both sets of measures to 47 bilingual Mandarin-English speakers...

Only a few studies have revealed using laparoscopic technique with limited resection of gastrointestinal stromal tumour (GIST) of the duodenum. A 68-year-old man was admitted to the hospital due to upper gastrointestinal (GI) bleeding. Evaluation revealed an ulcerated, bleeding GI tumour in the second part of the duodenum. After control of bleeding during gastroduodenoscopy, he underwent a laparoscopic wedge resection of the area. During 1.5 years of follow-up, the patient is disease free, eats drinks well, and has regained weight...

BACKGROUND: Imaging techniques that enhance visualisation of the anatomy may help prevent bile duct injury. Near-Infrared Fluorescence Imaging is such a technique. Previous experiments with ICG have shown that illumination of the extra-hepatic bile ducts is feasible. Yet, there is room for improvement in the visualisation of the target as compared to the background. Experiments with IRDye(®) 800CW show promising results. However, this dye is too expensive for routine clinical use. The aim of this study is to test the first applicability of two newly developed preclinical dyes regarding intraoperative imaging of the cystic duct and cystic artery, compared with IRDye(®) 800CW...

Portal hypertension induces congestion of the liver and spleen, thus any capsular or parenchymal injury to these organs can produce intractable bleeding which generally is not easily controlled. To cope with intractable bleeding such as being encountered during liver transplantation, we developed an infiltrating hemostasis technique as a conceptual shift from conventional application methods, in which fibrin glue is locally injected into the bleeding area on the liver or spleen. This technique, which uses a fibrin glue kit (2 ml kit; Greenplast, Green Cross, Seoul, Korea), consists of inserting the needle 0...

OBJECTIVES: Adenoma detection rate (ADR) is the most established indicator of the quality of screening colonoscopy. The effect of gastroenterology (GI) fellows on the quality of screening colonoscopies has been evaluated previously; however, the effect of starting a new GI fellowship program on the quality of screening colonoscopies has not been studied. The aim of our study was to assess the effects of starting a GI fellowship program and the participation of fellows in screening colonoscopies on ADR and other measures of quality...

INTRODUCTION: Postoperative cognitive dysfunction (POCD) is an adverse outcome of surgery that is more common after open heart procedures. The aim of this study is to investigate the role of tightly controlled blood glucose levels during coronary artery surgery on early and late cognitive decline. METHODS: 40 patients older than 50 years undergoing elective coronary surgery were randomized into two groups. In the "Tight Control" group (GI), the glycemia was maintained between 80 and 120mgdL(-1) while in the "Liberal" group (GII), it ranged between 80-180mgdL(-1)...
