RESUMO
BACKGROUND: Extragastric lesions are typically not misdiagnosed as gastric submucosal tumor (SMT). However, we encountered two rare cases where extrinsic lesions were misdiagnosed as gastric SMTs. CASE SUMMARY: We describe two cases of gastric SMT-like protrusions initially misdiagnosed as gastric SMTs by the abdominal contrast-enhanced computed tomography (CT) and endoscopic ultrasound (EUS). Based on the CT and EUS findings, the patients underwent gastroscopy; however, no tumor was identified after incising the gastric wall. Subsequent surgical exploration revealed no gastric lesions in both patients, but a mass was found in the left triangular ligament of the liver. The patients underwent laparoscopic tumor resection, and the postoperative diagnosis was hepatic hemangiomas. CONCLUSION: During EUS procedures, scanning across different layers and at varying degrees of gastric cavity distension, coupled with meticulous image analysis, has the potential to mitigate the likelihood of such misdiagnoses.
RESUMO
BACKGROUND: Colorectal cavernous hemangioma is a rare vascular malformation resulting in recurrent lower gastrointestinal hemorrhage, and can be misinterpreted as colitis. Surgical resection is currently the mainstay of treatment, with an emphasis on sphincter preservation. CASE SUMMARY: We present details of two young patients with a history of persistent hematochezia diagnosed with colorectal cavernous hemangioma by endoscopic ultrasound (EUS). Cavernous hemangioma was relieved by several EUS-guided lauromacrogol injections and the patients achieved favorable clinical prognosis. CONCLUSION: Multiple sequential EUS-guided injections of lauromacrogol is a safe, effective, cost-efficient, and minimally invasive alternative for colorectal cavernous hemangioma.
RESUMO
BACKGROUND: Gastric metastasis from renal cell carcinoma (RCC) is an extremely rare clinical entity. Due to an easily neglected RCC history, nonspecific symptoms and under-recognized endoscopic presentation may lead to a potential diagnostic pitfall in daily clinical practice. CASE SUMMARY: We present a case of metastatic gastric tumors arising from RCC 5 years after radical nephrectomy. Simultaneous, multifocal metastases to the gallbladder, pancreas and soft tissue were observed. One year previously, a solitary submucosal discoid tumor with a central depression was detected in the gastric fundus in a 65-year-old man. Endoscopic ultrasonography (EUS) showed a 1.12 x 0.38 cm lesion originating from the deeper mucosal layers with partially discontinuous submucosa. One year later, the endoscopic findings of the lesion showed various changes. A large lesion of the protruding type (2.5 cm × 2 cm) was found in the fundus at the same location. EUS showed a heterogeneous mass that involved the mucosa and submucosal layer. In addition, two small similar submucosal lesions 0.4-0.6 cm in size were detected. These lesions had a central depression, surface mucosal congestion and thickened vessels. The two adjacent lesions in the fundus were resected by endoscopic submucosal dissection. Based on the postoperative pathological analysis, the patient was diagnosed with gastric metastasis from RCC. CONCLUSION: Gastric metastasis from RCC should be considered in patients with a history of RCC irrespective of the time interval involved.
RESUMO
AIM: Accumulating evidence has explored the effect of mesalazine on irritable bowel syndrome (IBS). However, these studies remain inconsistent. Thus, a meta-analysis was conducted to estimate the role of mesalazine on IBS. METHODS: PubMed, Medline, Embase, Web of Science, and the Cochrane Library Database were searched for all relevant randomized, controlled, blinded trials on mesalazine in patients with IBS between January 1980 and October 2018. All statistical analyses were performed using Revman 5.3 software. A fixed-effects model was adopted, 95% confidence intervals for SMD was calculated. Heterogeneity was evaluated by χ test and I statistic. RESULTS: Five studies involving 387 participants were finally included in this meta-analysis. The results showed that the SMD for clinical efficacy on abdominal pain in IBS patients treated with mesalazine in comparison to placebo was 0.19 (95% CIâ=â-0.01 to 0.39, Pâ=â.06), which was statistically non-significant but clinically important. For beneficial effect of abdominal bloating, the SMD was 0.05 (95% CIâ=â-0.20 to 0.30, Pâ=â.70), which was statistically non-significant. In regard to clinical efficacy on defecation frequency per day, the results revealed that the SMD was 0.29 (95% CIâ=â-0.14 to 0.73, Pâ=â.18), which was statistically non-significant but clinically important. As for beneficial effect of general well-being, we found that the SMD was 0.41 (95% CIâ=â-0.75 to 1.58, Pâ=â.49), which was statistically non-significant. With respect to stool consistency, the SMD was 0.01 (95% CIâ=â-0.31 to 0.33, Pâ=â.96), which was statistically non-significant. For the effect of defecation urgency severity in IBS patients treated with mesalazine in comparison to placebo, we detected a surprising result with an SMD of 0.54 (95% CIâ=â0.05-1.04, Pâ=â.03), which was statistically significant. There was no significant difference between mesalazine group and placebo group on total mucosal immune cell counts of the patients with IBS with an SMD of -1.64 (95% CIâ=â-6.17 to 2.89, Pâ=â.48) and there was also no significant difference in adverse reactions between two groups with an SMD of 1.05 (95% CIâ=â0.76-1.46 Pâ=â.77). CONCLUSION: Mesalazine is not superior to placebo in relieving clinical symptoms of abdominal pain, abdominal bloating, and general well-being of IBS and has no advantage of reducing defecation frequency per day and immune cell infiltration and improving stool consistency though without adverse reactions of mesalazine compared with placebo. For defecation urgency severity, placebo is even superior to mesalazine for IBS patients. Thus, mesalazine might be a cost burden to patients without providing good effectiveness. In view of the small sample size of the current study and the differences in every experimental designs, this study has high heterogeneity and requires subsequent verification.

Heterotopic gastric mucosa (HGM) in the rectum is an extremely rare clinical entity which may be missed or misdiagnosed due to a lack of knowledge. In the present study, a 14-year-old girl visited our hospital due to a 5-year history of repeated hematochezia. Colonoscopy showed a solitary superficial depressed lesion approximately 5 cm in size and a concomitant 1.5 cm deep diverticulum in the rectum. Histological examination of the endoscopic biopsy showed typical ectopic gastric mucosa in the depressed lesion and inside the diverticulum. Narrow band imaging further confirmed the histological results. Endoscopic ultrasound indicated that the lesion originated from the mucosal layer, and partially involved the submucosal layer. Endoscopic submucosal dissection was performed in this patient due to the large size and shape of the lesion. No bleeding, perforation or other adverse events were observed. The presence of HGM in the diverticular cavity greatly increased the surgical difficulty. A literature review was also carried out in our study.

RATIONAL: Hematoma arising within an intrapancreatic accessory spleen (IPAS) is an extremely rare pathological entity. PATIENT CONCERN: We present the case of a 39-year-old man with acute abdominal pain. DIAGNOSES: The patient was initially diagnosed as pancreatic cystic neoplasm according to CT and MRI imaging. INTERVENTIONS: Distal pancreatectomy was conducted because of the possibility of malignancy. OUTCOMES: Surgical resection showed that the lesion was a hematoma in an IPAS. LESSONS: Our case indicated that the differential diagnosis of hematoma in IPAS should be born in mind for cases with cystic neoplasm in tail of pancreas and an epidermoid cyst arising within an intrapancreatic accessory spleen (ECIAS).

The aim of the study was to evaluate the diagnostic and therapeutic value of double-balloon entoroscopy (DBE) in small bowel diseases (SBDs) in China.A retrospective review of 674 consecutive patients who underwent DBE between January 2007 and November 2015 was conducted. Patients were divided into 3 groups by age, young group (<45 years), middle-aged group (45-65 years), and elderly group (>65 years). Data were collected with regard to demographics, clinical, endoscopic findings, complications, diagnostic yield, and management.A total of 729 DBE procedures were performed successfully in our series. More than 20 types of SBDs were found with the detection rate of 70.9%(517/729). The majority of patients were Crohn's disease (33.4%,225/674), followed by tumor (18.8%,127/674) and angioectasia (7.9%, 53/674). Endoscopic treatment was performed in 60 patients in which hemostasis (17,28.3%) and polypectomy (15,25%) were the predominant form of intervention used. Adverse events occurred in 6 patients (0.96%,6/729) including perforation, hemorrhage, aspiration pneumonia. No acute pancreatitis or other major complications occurred. Adenocarcinoma, GIST, and lymphoma were the most common tumor detected, the majority of tumors located in the jejunum (56.7%), The detection rate of angioectasia was also higher in the jejunum (54.7%),77.8% of Crohn's disease was located in the ileum. The positive rate of DBE in small bowel tumor and Crohn's disease were significantly higher than that of angioectasia (P<0.05). In young cohort, Crohn's disease (48.1%) was the most commonly diseases followed by tumor (10.4%) and nonspecific enteritis (7.1%). Yet in the elderly group, the majority of patients were tumor (27.6%); angioectasia (21.3%) was also detected frequently. The positive rate of capsule endoscopy was 75.44â%(202/268) which was a little high than DBE (67.9%, 182/268) (Pâ>â0.05). The obscure gastrointestinal bleeding (OGIB) was the most common indication, and the diagnostic yield was 71.8%.DBE is a useful diagnostic and therapeutic tool with high clinical practice value for the investigation of SBDs. With growing experience of endoscopist, we believe that DBE must be kept in mind as the first-line modality for suspected SBDs.

Introducción: la betatrofina es una novedosa adipoquina que provoca la proliferación de células ß pancreáticas e interviene en el metabolismo de los lípidos. Objetivos: el propósito de este estudio es evaluar el papel de la betatrofina en el síndrome metabólico. Método: se llevó a cabo un estudio hospitalario de casos y controles según sexo y edad. El nivel de betatrofina en suero fue evaluado mediante ensayo por inmunoabsorción ligado a enzimas. Se midieron las concentraciones en suero de 12 adipoquinas para evaluar las asociaciones con la betatrofina usando los kits comerciales Adipokine Magnetic Bead Panel. Los análisis estadísticos incluyeron correlación bivariada, análisis de curva ROC y análisis de regresión lineal multivariable. Resultados: el nivel de betatrofina en suero fue más elevado en pacientes con síndrome metabólico (997,36 ± 475,92 pg/ml, p = 0,001) que en los controles (735,35 ± 526,51 pg/ml). Frente al tercil más bajo, el tercil más alto del nivel de betatrofina mostró una asociación con mayor riesgo de síndrome metabólico (odds ratio ajustado = 3,521, intervalo de confianza [IC] 95% [1,191-10,413], p = 0,023). Se desarrolló la curva ROC de betatrofina para pronosticar la presencia de síndrome metabólico (área bajo la curva ROC = 0,682 [95% IC, 0,597-0,767], p < 0,001). Además, la betatrofina mostró correlación con distintos parámetros, como edad (r = 0,286, p < 0,001), índice de masa corporal (r = 0,160, p = 0,046), índice cintura-cadera (r = 0,241, p = 0,002), lipoproteína de alta densidad (r = -0,167, p = 0,037), lipoproteína de baja densidad (r = -0,195, p = 0,015), glucosa plasmática en ayunas (r = 0,266, p = 0,001), hemoglobina A1C (r = 0,314, p < 0,001), índice de resistencia a la insulina mediante HOMA (r = 0,272, p = 0,001) y diversas adipoquinas, entre ellas resistina (r = 0,571, p < 0,001), interleucina-8 (r = 0,435, p < 0,001), factor de necrosis tumoral alfa (r = 0,295, p = 0,011) y lipocalina-2 (r = 0,346, p = 0,003). Conclusiones: este estudio demuestra que la betatrofina en suero desempeña una importante labor en el síndrome metabólico, implicando la regulación del metabolismo de la glucosa y los lípidos y la inflamación.

Background: Betatrophin is a novel adipokine that provokes pancreatic β-cell proliferation and is involved in lipid metabolism. Aims: This study aims to evaluate the role of serum betatrophin in metabolic syndrome (MetS). Methods: A hospital-based, age-/gender-matched case control study was conducted. The serum betatrophin level was evaluated by enzymelinked immunosorbent assay. Serum concentrations of 12 adipokines were measured to assess their associations with serum betatrophin, using commercial Adipokine Magnetic Bead Panel kits. Statistical analyses included bivariate correlation, receiver operating characteristic (ROC) curve, and multivariate stepwise linear regression. Results: Serum betatrophin showed a higher level in MetS patients (997.36 ± 475.92 pg/ml, p = 0.001) compared with controls (735.35 ± 526.51 pg/ml). Compared with the lowest tertile, the highest tertile of serum betatrophin level indicated an association with higher risk of MetS (adjusted odds ratio = 3.521, 95% confidence interval [CI] [1.191-10.413], p = 0.023). ROC curve of betatrophin was developed to predict the presence of MetS (area under ROC = 0.682 [95% CI, 0.597-0.767], p < 0.001). Furthermore, betatrophin correlated with several parameters, e.g. age (r = 0.286, p < 0.001), body mass index (r = 0.160, p = 0.046), waist-to-hip ratio (r = 0.241, p = 0.002), high-density lipoprotein cholesterol (r = -0.167, p = 0.037), low-density lipoprotein cholesterol (r = -0.195, p = 0.015), fasting plasma glucose (r = 0.266, p = 0.001), hemoglobin A1C (r = 0.314, p < 0.001), homeostasis model assessment of insulin resistance (r = 0.272, p = 0.001), and various adipokines, e.g. resistin (r = 0.571, p < 0.001), interleukin-8 (r = 0.435, p < 0.001), tumor necrosis factor-α (r = 0.295, p = 0.011) and lipocalin-2 (r = 0.346, p = 0.003). Conclusions: This study supports that serum betatrophin plays an important role in MetS, involving the regulations of glucose and lipid metabolism and inflammation (AU)

Recent animal studies support close associations of Periostin with hepatosteatosis and steatohepatitis. This study is to evaluate the role of serum periostin in non-alcoholic fatty liver disease (NAFLD). A hospital-based age-/sex-matched case-control study was conducted. Binary logistic regression and receiver operating characteristic (ROC) curve were performed. Serum adipokines were measured by Adipokine Magnetic Bead Panel kits. The serum concentration of Periostin in NAFLD (1914.16 [1323.59-2654.88] ng/ml, P < 0.001) was higher than it in control (1244.94 [837.87-2028.55] ng/ml). The frequency of NAFLD grew (29.8, 52.6, and 67.2%, P < 0.001), as Periostin concentration increased among its tertiles. Compared with the 1st tertile, the 2nd and the 3rd tertiles of Periostin indicated significant associations with higher odds of NAFLD [adjusted odds ratio = 2.602 (95% confidence interval (CI) 1.030-6.575), P = 0.043 and 2.819 (95% CI 1.629-4.878), P < 0.001]. ROC curve of Periostin was developed to predict the presence of NAFLD (area under ROC = 0.693 [95% CI 0.614-0.771], P < 0.001). Lastly, Periostin correlated with several adipokines, including Resistin (r = 0.269, P = 0.018), Adiponectin (r = -0.352, P = 0.002), Interleukin (IL)-6 (r = 0.359, P = 0.001), IL-8 (r = 0.364, P = 0.001), Lipocalin-2 (r = 0.623, P < 0.001), Hepatocyte growth factor (r = 0.522, P < 0.001), and Nerve growth factor (r = 0.239, P = 0.036). It suggests Periostin as a potential biomarker in the management of NAFLD.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is a great health burden. Neuregulin 4 (Nrg4) is a recently identified secret factor that may be associated with NAFLD. AIM: To investigate the association between serum Nrg4 level and NAFLD by conducting a case-control study. METHOD: A total of 174 subjects were included. 87 NAFLD subjects and 87 age- and sex-matched non-NAFLD controls were identified by hepatic ultrasound examination. Anthropometric and biochemical data were measured and recorded. Serum Nrg4 level was evaluated by using enzyme-linked immunosorbent assay. SPSS software was used for statistical analyses. RESULTS: Compared to the controls, subjects with NAFLD presented with reduced level of serum Nrg4 (0.40 (0.27, 0.55) vs. 0.50 (0.30, 0.81)ng/mL (median (interquartile range)), P=0.029). By multivariate logistic regression analysis, reduced serum levels of Nrg4 were associated with higher NAFLD odds (OR=0.251, 95% confidence interval=0.081-0.779, P=0.017). By dividing the distribution of serum Nrg4 level into quartiles, there was borderline statistical difference of NAFLD prevalence among the four groups (P=0.058). There was no significant difference of serum Nrg4 levels in subjects according to the grades of fatty liver by ultrasound (P=0.080). No statistical difference of serum Nrg4 level was observed between obese and non-obese subjects (P=0.932). CONCLUSION: Decreased serum Nrg4 level is prevalent in NAFLD subjects compared to non-NAFLD controls, and is an independent risk factor associated with NAFLD, indicating that Nrg4 might have a protective role in the development of NAFLD.

AIM: To analyze the benefits and harms of pancreatic cancer screening in familial high-risk individuals (HRIs). METHODS: Studies were identified by searching PubMed, EBSCO, ClinicalTrials.gov and the Cochrane database from database inception to June 2014. We also obtained papers from the reference lists of pertinent studies and systematic reviews. English-language trials and observational studies were searched. The key words used as search terms were "screening" and "surveillance". Cost-effectiveness, diagnostic rate, survival rate, mortality and adverse events were the outcomes of interest. Age, sex, lifestyle and other confounding factors were also considered. However, anticipating only a few of these studies, we also included observational studies with or without control groups. We also included studies concerning the anxiety associated with pancreatic cancer risk and other psychological changes in familial HRIs. We extracted details on study design, objectives, population characteristics, inclusion criteria, year of enrollment, method of screening, adjusted and unadjusted mortality, cost-effectiveness and adverse events from the included studies. Studies were assessed using the Reporting of Observational studies in Epidemiology (STROBE) checklist. RESULTS: Sixteen studies on pancreatic cancer screening were included. Five studies included control groups, nine were observational studies without control groups, and the other two studies investigated the worry associated with pancreatic cancer risk. We found that pancreatic cancer screening resulted in a high curative resection rate (60% vs 25%, P = 0.011), longer median survival time (14.5 mo vs 4 mo, P < 0.001), and higher 3-year survival rate (20% vs 15.0%, P = 0.624). We also found that familial HRIs had a higher diagnostic rate of pancreatic tumors than controls (34% vs 7.2%, P < 0.001). In patients who underwent regular physical examinations, more stage I pancreatic cancers were observed (19% vs 2.6%, P = 0.001). In addition, endoscopic ultrasonography, which was the main means of detection, diagnosed 64.3% of pancreatic cancers. In comparison, endoscopic retrograde cannulation of the pancreas, magnetic resonance imaging, and computed tomography diagnosed 28.6%, 42.9%, and 21.4%, respectively. For mass lesions, instant surgery was recommended because of the beneficial effects of post-operative chemotherapy. However, in patients with intraductal papillary mucinous neoplasms, we did not find a significant difference in outcome between surgery and follow-up without treatment. Moreover, pancreatic cancer screening in familial HRIs had a greater perceived risk of pancreatic cancer (P < 0.0001), higher levels of anxiety regarding pancreatic cancer (P < 0.0001), and increased economic burden. CONCLUSION: Pancreatic cancer screening in familial HRIs is associated with a higher detection rate and longer survival, although screening may influence psychological function and increase the economic burden.

AIM: To investigate whether Helicobacter pylori (H. pylori) infection is associated with glycemic control and whether hyperglycemia is modified by eradication therapy. METHODS: The databases of PubMed, Cochrane Library, Chinese BioMedicine Web Base and Chinese Science and Technology Journals were searched from inception to June 2014. Studies examining the association between H. pylori infection and glycemic control and/or the effect of eradication treatment on glycemic control in diabetic humans were eligible for inclusion. Meta-analyses were conducted using the Review Manager software version 5.2. The outcome measures are presented as weighed mean differences (WMDs) with 95% confidence intervals (CIs). Statistical heterogeneity was assessed by the Cochran Q test and the I(2) statistic. RESULTS: A total of 21 relevant publications were identified. A meta-analysis of 11 studies with 513 patients with diabetes mellitus (DM) showed significantly lower glycosylated hemoglobin (HbA1c) levels in the H. pylori-negative than H. pylori-positive DM participants (WMD = 0.43, 95%CI: 0.07-0.79; P = 0.02). In children and adolescents with type 1 DM (T1DM), there was a positive association between H. pylori infection and HbA1c level (WMD = 0.35, 95%CI: 0.05-0.64; P = 0.02), but there was no difference in those with type 2 DM (T2DM, WMD = 0.51, 95%CI: -0.63-1.65; P = 0.38). A meta-analysis of six studies with 325 T2DM participants showed a significant difference in the fasting plasma glucose levels between H. pylori-positive and H. pylori-negative participants (WMD = 1.20, 95%CI: 0.17-2.23; P = 0.02). Eradication of H. pylori did not improve glycemic control in the T2DM participants in a three-month follow-up period (HbA1c decrease: WMD = -0.03, 95%CI = -0.14-0.08; P = 0.57; fasting plasma glucose decrease: WMD = -0.06, 95%CI: -0.36-0.23; P = 0.68). Glycemic control was significantly better in T1DM participants who were not reinfected than in those who were reinfected (HbA1c: WMD = 0.72, 95%CI: 0.32-1.13: P = 0.00). CONCLUSION: H. pylori infection is associated with poorer glycemic control in T1DM patients, but eradication may not improve glycemic control in DM in a short-term follow-up period.

Nonalcoholic fatty liver disease (NAFLD) is increasingly regarded as a hepatic manifestation of metabolic syndrome. Though with high prevalence, the mechanism is poorly understood. This study aimed to investigate the effects of p21 on free fatty acid (FFA)-induced steatosis in L02 cells. We therefore analyzed the L02 cells with MG132 and siRNA treatment for different expression of p21 related to lipid accumulation and lipotoxicity. Cellular total lipid was stained by Oil Red O, while triglyceride content, cytotoxicity assays, lipid peroxidation markers and anti-oxidation levels were measured by enzymatic kits. Treatment with 1 mM FFA for 48 hr induced magnificent intracellular lipid accumulation and increased oxidative stress in p21 overload L02 cells compared to that in p21 knockdown L02 cells. By increasing oxidative stress and peroxidation, p21 accelerates FFA-induced lipotoxic effect in L02 cells and might provide information about potentially new targets for drug development and treatments of NAFLD.
