OBJECTIVES Isoniazid (INH) prophylaxis is recommended for the prevention of tuberculosis (TB) reactivation before or/and during initiation of treatment with tumour necrosis factor antagonists (anti-TNF agents). Nonetheless, the long-term effectiveness of chemoprophylaxis is not clear. In this study, we aimed to evaluate the characteristics of patients who developed TB reactivation in spite of INH prophylaxis associated with anti-TNF treatment. PATIENTS AND METHODS In this retrospective study, medical records of 1263 patients with inflammatory bowel disease were reviewed. Baseline TB screening tests (purified protein derivative test and/or QuantiFERON-TB Gold test) were performed on all patients before initiation of anti-TNF therapy. Patients with purified protein derivative of more than 5 mm and/or a positive result of the QuantiFERON-TB Gold test received INH prophylaxis for 9 months. We analysed the data of patients diagnosed with TB reactivation during the anti-TNF treatment despite INH chemoprophylaxis. RESULTS Overall, 175 patients underwent anti-TNF treatment. Sixty of these 175 patients had pretreatment testing showing latent TB infection and therefore were treated concomitantly with INH for 9 months in addition to their anti-TNF treatment. TB reactivation occurred in four of these 60 co-INH/anti-TNF treated patients. Active TB was diagnosed after 37.5±27 (range: 18-84) months of anti-TNF treatment. In two of the four patients that active TB was diagnosed, was also detected other Mycobacterium spp.: M. bovis in one patient and M. genavense in the other one. CONCLUSION INH chemoprophylaxis may not prevent the reactivation of TB during anti-TNF therapy in the long-term. Patients should be carefully and periodically screened for TB reactivation during anti-TNF therapy.

Introduction Gastroesophageal reflux disease (GERD) is more frequent in patients with diabetes mellitus (DM).The aim of the present study was to evaluate gastroesophageal reflux (GER) in asymptomatic patients with DM using 24-h pH impedance. Materials and Methods 19 healthy controls and 35 patients with DM without typical GERD symptoms were enrolled in the study. A 24-h pH-impedance study, esophageal manometry and gastroscopy were performed on all patients with DM. In the control group, an impedance study was performed on all subjects, and gastroscopy and esophageal manometry were performed on those who consented to the procedures. Patients with diabetes were categorized as obese [body mass index (BMI)>30 kg/m2] or non-obese (BMI Results The mean BMI was similar in the control group (27.3±2.6 kg/m2) and the diabetic group (28.7±5 kg/m2) (p>0.05).Erosive esophagitis was found in 7.5% of the DM group. Esophageal dysmotility was higher in diabetics compared to the control group (45.5 vs. 11%, p=0.04). Neuropathy was found to be an independent risk factor for dysmotility. The mean DeMeester score (DMS) (25.6±32.5 vs. 11.2±17, p=0.01) and bolus exposure time (2.1±1.3 vs.1.3±1.3 min, p=0.009) were higher in the DM group compared with the control group.The difference was mainly observed between obese diabetics and the control group (p Conclusion Acid reflux is common in patients with diabetes.GER is associated with the existence of obesity rather than hyperglycemia.

Objective: Natural course and clinical outcomes of chronic hepatitis B virus (HBV) infection is closely releated to immun responses of host and viral factors. Studies have suggested that there is strongly correlation between the level of IL-17 and especially of advanced liver damages associated with HBV. Role of IL-17 on natural course of chronic hepatitis B disease is yet to be fully clarified. This study aimed to evaluate the correlation between serum IL-17 levels with histological, virological, serological and biochemical data of chronic hepatitis B patients. Material and Method: Simultaneous liver biopsy and blood samples were obtained from 88 with chronic HBV enfection. Ishak modified histological activity index system was used for histological evaluation.The patients were divided into three groups taking into account by scoring as none/mild (F0-1), moderate / severe (F2-4) and cirrhosis (F5-6) according to the stages of fibrosis (F). It was analyzed using enzyme-linked immunosorbent assay (ELISA) to IL-17 levels in serum samples. Results: A total of 88 CHB patients were evaluated, with an average age of 41.77±13.39, 43 male and 45 female. Fibrosis stage of 64 (72.7%) of the patients included in the study was determined as F2-4. There were no statistically significant correlation between serum IL-17 levels with histological, virological, serological and biochemical data of patients. Conclusion: These data indicate that the immunopathological role of IL-17 on HBV-related especially low and moderate liver injuries are limited.

Surgical resection is an unavoidable part of the current treatment options for Crohn's disease (CD), and more than half of patients develop recurrence. The aim of this study was to investigate the predictors for recurrence in the long-term follow-up of CD patients after surgery. Medical records of consecutive CD patients who were operated on between January 2003 and January 2015 were retrospectively analyzed. Data including demographic and clinical characteristics of the patients were recorded. Recurrence was evaluated based on the Crohn's Disease Activity Index or endoscopic findings. The majority of 112 patients were males (n = 64, 57.1%), and 61 (54.4%) of them were active smokers. The median follow-up was 113 (range: 61-197) months. Disease recurrence occurred in 16 (14.3%) patients at a median of 13.5 months. The endoscopic recurrence rate was 8% (n = 9) at 1 year, 12.5% (n = 14) at 5 years, and 13.4% (n = 15) at 10 years. One (0.9%) patient underwent colonoscopic balloon dilatation at 1 year, and 7 (6.3%) patients needed re-resection at a median of 36 months. The age of the patient at the time of diagnosis (P = .033), penetrating disease behavior (P = .011), intra-abdominal abscess (P = 0.040) and, concomitant fistula and intra-abdominal abscess (P = .017) were associated with disease recurrence. Our study results suggest that the patients' age at the time of diagnosis, penetrating disease, intra-abdominal abscess, and concomitant fistula and abscess are the risk factors for CD recurrence after surgery., NA

Introduction COVID-19 caused by the SARS-CoV-2 continues to spread rapidly across the world. In our study, we aim to investigate the relationship between the liver enzymes on admission (AST, ALT, ALP, GGT) and severity of COVID-19. We evaluated course of disease, hospital stay, liver damage and mortality. Materials and methods Our study included 614 patients who were hospitalized with the diagnosis of COVID-19 between 03.16.20 and 05.12.20. Patients with liver disease, hematological and solid organ malignancy with liver metastases were excluded, resulting in 554 patients who met our inclusion criteria. We retrospectively evaluated liver transaminase levels, AST/ALT ratio, cholestatic enzyme levels and R ratio during hospital admission and these were compared in terms of morbidity, mortality and clinical course. Results Mean age of 554 subjects were 66.21 ± 15.45 years, 328 (59.2%) were men. The mean values of liver enzymes on admission were AST (36.2 ± 33.6 U/L), ALT (34.01 ± 49.34 U/L), ALP (78.8 ± 46.86 U/L), GGT (46.25 ± 60.05 U/L). Mortality rate and need for intensive care unit were statistically significant in subjects that had high ALT–AST levels during their admission to the hospital (p = 0.001). According to the ROC analysis AST/ALT ratio was a good marker of mortality risk (AUC = 0.713: p = 0.001) and expected probability of intensive care unit admission (AUC = 0.636: p = 0.001). R ratio, which was used to evaluate prognosis, showed a poor prognosis rate of 26.5% in the cholestatic injury group, 36.1% in the mixed pattern group and 30% in the hepato-cellular injury group (p 0.001). Conclusions ALT–AST elevation and AST/ALT ratio >1 was associated with more severe course and increased mortality in COVID-19.

Background/aims Recently, mucosal inflammation has been proposed to be one of the mechanisms underlying the pathophysiology of irritable bowel syndrome (IBS); however, there are controversial results regarding this hypotheses. Our aim was to evaluate immune cell infiltration in rectal and ileal biopsy specimens of patients with IBS and to compare it with those of healthy controls. Materials and methods In total, 36 patients with IBS (15 with diarrhea and 21 with constipation) and 16 healthy volunteers were enrolled. Ileocolonoscopy and ileal/rectal biopsies were performed. Rectal and terminal ileal biopsy specimens were evaluated for mucosal immune cell infiltration using immunohistochemical analysis. Serotonin positivity as well as counts of intraepithelial lymphocytes (IEL) and CD4+, CD8+, CD20+, and CD3+ cells were determined by a single pathologist who is an expert in the gastrointestinal system. Results CD3+ and CD4+ cell counts in rectal and terminal ileal biopsy specimens were lower in the IBS group than in the controls. Conversely, there was no statistically significant difference between the IBS and control groups in terms of serotonin positivity as well as counts of IEL and CD20+ and CD8+ cells. Comparison between the IBS subgroups revealed a higher number of IEL in rectal biopsy specimens of the diarrhea dominant group. In the IBS subgroups, immune cell counts in terminal ileal and rectal biopsy specimens showed a positive correlation. Conclusion IBS and its subgroups showed lower immune cell counts than the controls in our study. These results indicate that there is no significant mucosal inflammation in homogeneous groups of patients with IBS. Rectal biopsies may be sufficient for the evaluation of inflammation in IBS.

Aim: To investigate clinical, etiological, and prognostic features in patients with hepatocellular carcinoma. Methods: Patients with hepatocellular carcinoma who were followed-up from 2001 to 2011 were included in the study. The diagnosis was established by histopathological and/or radiological criteria. We retrospectively reviewed clinical and laboratory data, etiology of primary liver disease, imaging characteristics and treatments. Child-Pugh and Barcelona Clinic Liver Cancer stage was determined at initial diagnosis. Kaplan-Meier survival analysis was done to find out treatment effect on survival. Risk factors for vascular invasion and overall survival were investigated by multivariate Cox regression analyses. Results: Five hundred and forty-five patients with hepatocellular carcinoma were included in the study. Viral hepatitis was prevalent and 68 patients either had normal liver or were non-cirrhotic. Overall median survival was 16 (13-19) mo. Presence of extrahepatic metastasis was associated with larger tumor size (OR = 3.19, 95% CI: 1.14-10.6). Independent predictor variables of vascular invasion were AFP (OR = 2.95, 95% CI: 1.38-6.31), total tumor diameter (OR = 3.14, 95% CI: 1.01-9.77), and hepatitis B infection (OR = 5.37, 95% CI: 1.23-23.39). Liver functional reserve, tumor size/extension, AFP level and primary treatment modality were independent predictors of overall survival. Transarterial chemoembolization (HR = 0.38, 95% CI: 0.28-0.51) and radioembolization (HR = 0.36, 95% CI: 0.18-0.74) provided a comparable survival benefit in the real life setting. Surgical treatments as resection and transplantation were found to be associated with the best survival compared with loco-regional treatments (log-rank, P < 0.001). Conclusion: Baseline liver function, oncologic features including AFP level and primary treatment modality determines overall survival in patients with hepatocellular carcinoma., NA

Familial Mediterranean fever (FMF) is the most common form of autoinflammatory diseases. We aimed to evaluate the small bowel mucosa by capsule endoscopy (CE) in FMF patients for investigation of other possible causes of abdominal pain.The study group consisted of 41 patients with FMF. A standard questionnaire was used to record the gastrointestinal symptoms, other clinical findings, Mediterranean fever gene (MEFV) mutations, and history of medications including non-steroidal anti-inflammatory drugs (NSAIDs). Gastroscopy, colonoscopy and small bowel CE were performed in all patients, and biopsies were taken from terminal ileum and duodenum.The mean age of the patients was 34 ± 11 years, 63% of them were female, and 76.5% of them were carrying MEFV exon 10 mutations. Only one patient used NSAIDs in addition to colchicine. In endoscopic investigations, gastric erosion was detected in only one patient, and no significant findings were detected in colonoscopy. CE showed small bowel mucosal defects in 44% (erosions in 26.8%, ulcer in 17.1%) and edema in 29.3% of the patients. Most (64%) of the ulcer and erosions were localized to jejunum, and only 24% were in ileum. Mitotic changes as an indirect finding of colchicine toxicity were not different from the changes observed in samples of independent group of patients with irritable bowel syndrome.Mucosal defect was observed in half of the FMF patients, which may be associated with underlying inflammation or chronic colchicine exposure. Detection of nonspecific chronic inflammation without mitotic changes supports that mucosal defects may be associated with the autoinflammatory process.

WOS: 000389516600014 PubMed ID: 27619844 Objectives: Serum alanine aminotransferase (ALT) is a controversial marker for disease monitoring in hepatitis B e antigen (HBeAg)-negative chronic hepatitis B (CHB) patients. The aim of this study was to determine the fibrosis stage and histological activity index (HAI) in HBeAg-negative CHB patients with persistently normal ALT (PNALT) and high serum HBV DNA (>= 2000 IU/ml) and to investigate clinical risk factors for the requirement of treatment through the examination of liver biopsy specimens. Methods: HBeAg-negative CHB patients with PNALT (= 2000 IU/ml) were included. HBV fibrosis stage and HAI were scored according to the Ishak system. Multivariate logistic regression analysis was used to estimate the independent risk factors for fibrosis stage >= 2 and/or HAI >= 6. Receiver operating characteristic curve analysis was used to determine an optimal age cut-off for liver biopsy. Results: A total 120 patients were enrolled. These patients had a mean HBV DNA level of 123 680 +/- 494 500 IU/ml; the HBV DNA load was 2000-20 000 IU/ml in 68 patients (56.6%) and >= 20 000 IU/ml in 52 (43.4%). Eighteen patients (15%) had moderate-to-severe histological activity (HAI >= 6). Forty-three patients (35.9%) had a fibrosis stage >= 2. Forty-eight patients (40%) had a fibrosis stage >= 2 and/or HAI >= 6. On multivariate logistic regression analysis, independent variables associated with fibrosis stage >= 2 and/or HAI >= 6 included age and HBV DNA viral load. Patients with HBV DNA 2000-20 000 IU/ml were more likely to require treatment compared to those with a viral load >= 20 000 IU/ml. The optimal age cut-off to predict fibrosis stage >= 2 and/or HAI >= 6 was 46 years. Conclusions: Significant liver damage was detected in 40% of CHB patients with PNALT and high HBV DNA upon biopsy. Age and HBV DNA viral load were independent predictors of significant liver damage. A biopsy to determine the degree of liver damage is advisable for CHB patients older than 46 years.

Objective This study evaluated the risks and outcomes of capsule retention during capsule endoscopy (CE) for investigating small bowel disease. Capsule retention is the most serious complication of CE. Methods Before CE, the gastrointestinal tract was evaluated for blockages with computerized tomography. Analysis of CE was made retrospectively. Results Capsule endoscopy was used to investigate obscure bleeding (90.2%; n=324) or other symptoms (9.8%; n=35). The capsule retention rate was 11/359 (3.1%); it was retained in a malignant lesion area (adenocarcinoma or melanoma) in two patients (18.2%), in the small bowel in an ulcerated area in five patients (45.5%), and in the oesophagus/stomach in four patients (36.4%) due to dysmotility. None of the patients had symptoms of obstruction. Conclusions Scanning patients before CE did not predict capsule retention. Retention is a complication of CE, but occurs as a result of the underlying disease. The risk of retention is increased in patients with motility disorders, suspected small bowel ulcers or malignancies., NA

The urachus establishes a connection between the dome of the bladder and the umbilicus throughout fetal life. If the urachus does not close completely, malignancy is a potential complication. The primary treatment for malignant urachal tumor is surgical excision. A 61-year-old male patient diagnosed with urachal carcinoma had undergone partial cystectomy 25 years previously. Twenty years later, local recurrence was treated with another partial cystectomy without umbilical remnant excision. Recurrence at the umbilical site was excised 2 years later, but intraperitoneal invasion had occurred, and the patient underwent a total colectomy at that time. Local disease and disseminated metastases in the thorax and intra- and extraperitoneal areas were noted upon admission to our hospital. Urachal carcinomas are usually aggressive tumors, and surgical treatment should include partial or radical cystectomy and excision of the urachus and umbilicus, to prevent local recurrence and distant metastasis.

Background & Aims To evaluate the efficacy of tenofovir in chronic hepatitis B (CHB) patients with adefovir resistance (ADF-R) and suboptimal response to adefovir (ADF-S). Methods Nucleos(t)ide analogue (NA)-naive patients and patients with previous adefovir failure receiving tenofovir therapy for at least 6 months were included in the study. Biochemical and virological tests were obtained at baseline and 3-month intervals in the first year and every 6 months thereafter. The primary outcome measure was complete virological response (CVR) (HBVDNA

Background Tenofovir (TDF) has similar antiviral efficacy in both treatment-naive and lamivudine-resistant chronic hepatitis B (CHB) patients. Data on TDF use in patients with adefovir (ADV) resistance is inconsistent. The aim of our study was to assess antiviral efficacy of TDF against nucleoside analogue-naive (NN) and ADV-resistant (ADV-R) CHB and suboptimal responders to ADV (ADV-S). Methods A database of 135 CHB patients treated with TDF was analysed. A total of 37 patients with incomplete data were excluded and analysis was performed in 98 (44 NN, 30 ADV-R and 24 ADV-S). Patients with primary ADV-R mutations had either A181T/V or N236T mutations or both. HBV DNA was measured at 3-month intervals until month 24. Primary outcome measures were comparison of the decline of HBV DNA between the three treatment groups. Results NN patients had higher baseline HBV DNA compared with ADV-R and ADV-S patients (6.08 log10 IU/ml versus 5.53 and 4.88, respectively; P=0.002). By exponential regression analysis, HBV DNA decline kinetics differed between the three groups. HBV DNA decline was faster in NN patients compared to ADV-R and ADV-S CHB patients ( P=0.002 and P=0.004, respectively). Undetectable HBV DNA was achieved in 77.2%, 60% and 75% of NN, ADV-R and ADV-S CHB patients, respectively, at month 12 ( P= not significant). Conclusions HBV DNA decline is slower in ADV-experienced patients compared with treatment-naive patients. The clinical significance of this slow response may be important in patients with critical liver reserve and high viral load. Optimal combination treatment (TDF+ entecavir) could be considered in these patients.

Background & Aims We investigated the association between interferon λ 3 ( IFNL3 ) genotype (also known as interleukin 28B) and response to IFNα therapy in patients with chronic hepatitis D virus (HDV) infection. Methods We studied IFNL3 genotypes of 32 patients (19 men; median age, 42.5 y) with chronic HDV infection. Nineteen patients (59%) were treated with pegylated IFNα and 13 patients (41%) were treated with standard IFNα, for at least 12 months. Levels of HDV RNA were measured before the initiation of treatment and every 6 months thereafter; patients were followed up for a median time of 16 months (range, 6–164 mo) after treatment ended. We used real-time polymerase chain reaction to classify the IFNL3 polymorphism rs12979860 as CC, CT, or TT, and rs8099917 as TT, GT, or GG. A virologic response was defined as undetectable HDV RNA in serum, and a sustained virologic response (SVR) was defined as undetectable HDV RNA after cessation of treatment until the end of the follow-up period. We evaluated the association between IFNL3 polymorphism and treatment response using univariate and multivariate analyses. Results After treatment, a response was achieved in 16 patients (50%) and an SVR was achieved in 9 (28%). The percentages of patients with CC, CT, and TT at rs12979860 were 47%, 47%, and 6%, respectively; the percentages of patients with TT, GT, and GG at rs8099917 were 69%, 28%, and 3%, respectively. Rates of SVR were 27%, 27%, and 50% in patients with CC, CT, TT at rs12979860 ( P = .78 for CC vs CT vs TT) and 36%, 11%, and 0% in patients with TT, GT, and GG at rs8099917 ( P = .30 for TT vs GT vs GG). Conclusions The IFNL3 polymorphisms rs12979860 and rs8099917 do not significantly affect responses of patients with chronic HDV infection to treatment with IFNα.

We evaluated the efficacy of tenofovir disoproxil fumarate (TDF) in patients with lamivudine failure (LAM-F) in comparison with that in nucleoside/nucleotide analogue (NA)-naïve patients with chronic hepatitis B (CHB). The criteria for inclusion were being NA naïve or having previous LAM-F and receiving TDF therapy for at least 6 months. Biochemical and virological tests were performed at the baseline, at 3-month intervals in the first year, and every 6 months thereafter. The primary outcome measure for efficacy was a complete virological response (CVR), defined as an HBV DNA level of P = 0.10) and HBeAg-positive patients (67% versus 83% at month 36, P = 0.48). According to the multivariate Cox regression model, only HBeAg positivity (hazard ratio [HR], 0.39; 95% confidence interval [CI], 0.26 to 0.59; P < 0.001) and a high baseline HBV DNA level (HR, 0.44; 95% CI, 0.29 to 0.67; P < 0.001) had a significant influence on the time to a CVR. The similar cumulative CVR rates during the follow-up show that TDF has comparable efficacy in lamivudine-experienced and NA-naïve patients, and the presence of resistance mutations did not alter the response rates.

WOS: 000373288400004 PubMed ID: 27076873 AIM: To assess the clinical impact of capsule endoscopy (CE) in the long-term follow-up period in patients with obscure gastrointestinal bleeding (OGIB). METHODS: One hundred and forty-one patients who applied CE for OGIB between 2009 and 2012 were retrospectively analyzed, and this cohort was then questioned prospectively. Demographic data of the patients were determined via the presence of comorbid diseases, use of non-steroidal anti-inflammatory drugs anticoagulant-antiaggregant agents, previous diagnostic tests for bleeding episodes, CE findings, laboratory tests and outcomes. RESULTS: CE was performed on 141 patients because of OGIB. The capsule was retained in the upper gastrointestinal (GI) system in two of the patients, thus video monitoring was not achieved. There were 139 patients [62% male, median age: 72 years (range: 13-93 years) and a median follow-up duration: 32 mo (range: 6-82 mo)]. The overall diagnostic yield of CE was 84.9%. Rebleeding was determined in 40.3% (56/139) of the patients. The rebleeding rates of patients with positive and negative capsule results at the end of the follow-up were 46.6% (55/118) and 4.8% (1/21), respectively. In the multivariate analysis, usage of NSAIDs, anticoagulant-antiaggregant therapies (OR = 5.8; 95% CI: 1.86-18.27) and vascular ectasia (OR = 6.02; 95% CI: 2.568-14.146) in CE were detected as independent predictors of rebleeding. In the univariate analysis, advanced age, comorbidity, and overt bleeding were detected as predictors of rebleeding. CONCLUSION: CE is a reliable method in the diagnosis of obscure GI bleeding. Negative CE correlated with a significantly lower rebleeding risk in the long-term follow-up period.

Background To determine the efficacy of pegylated interferon-α (PEG-IFN-α) therapy for 24 months in chronic delta hepatitis (CDH). Methods Patients with CDH who were treated by PEG-IFN-α2a or -2b for 24 months were included in the study. Demographic, biochemical and virological parameters were recorded at baseline and during follow-up. All included patients completed a treatment period of 24 months and at least a 6 month (range 6-60) follow-up period. Biochemical and virological response rates at end of treatment and end of follow-up were calculated, and predictors of sustained virological response (SVR) were analysed. Results In total, 32 patients (22 males; mean age ± SD 42.7 ± 12 years) with CDH who were treated with PEG-IFN-α2a (180 µg) or -2b (1.5 µg/kg) once a week subcutaneously for 24 months were included in the study. All patients had compensated liver disease (25 [78%] were non-cirrhotic), increased transaminase levels and HDV RNA positivity at baseline. Genotypic analyses of HDV showed genotype I in all. Mean duration of follow-up was 19.5 months. At the end of treatment, virological response was achieved in 16 (50%) patients. SVR at the end of follow-up was achieved in 15 (47%) patients. A negative HDV RNA at 6 months of treatment was the only predictor of SVR (OR = 20; 95% CI 2, 195; P = 0.01). Conclusions PEG-IFN-α treatment achieved SVR in approximately half of the patients with CDH, and relapse rate was very low during the follow-up. Negativity of HDV RNA at 6 months may predict SVR in CDH.

Success of Two Different Endoscopic Submucosal Resection Methods in Gastric Subepithelial Lesions Cetin Karaca*, Ozlem Mutluay Soyer, Filiz Akyuz, Bulent Baran, Asli Ormeci, Suut Gokturk, Kadir Demir, Sadakat Ozdil, Fatih Besisik, Sabahattin Kaymakoglu Istanbul University, Istanbul School of Medicine, Istanbul, Turkey Aim: Gastric subepitelial lesions (GSL) are incidentally detecting during gastroscopy. Endoscopic ultrasound’s (EUS) success is limited in accurate diagnosis. Endoscopic submucosal resection (ESMR) is needed for accurate diagnosis of GSL’s. In this study, we evaluated the usefulness of ESMR with a esophageal band ligation device and saline solution-assisted and snare technique in GSL. Materials and Methods: We analysed gastroscopically detected and ESMR applied GSL cases, retrospectively. GSL’s characterising executed using EUS before ESMR. ESMR executed using saline solution-assisted and snare technique in %50 of cases and using band ligation in rest of cases. Results: A total of 16 patients (10 women, mean age 52.4 years) with an endoscopically resected GSL were included. In EUS examination lesions found %62.5 submucosal, %12.5 mucosal, %25 muscularis propria oriented. The mean size of the 16 lesions was 11mm (range 5-20mm). An endoscopic cap band mucosectomy device was used to resect 8 (50%) lesions, whereas 8 (50%) were resected with a saline solutionassisted and snare technique. ESMR was successfully performed in all 16 GSLs. The en bloc resection rate was 100% (16/16). Lesions pathological diagnosis are found as; ectopic pancreas 3 (%18.7), inflammatory fibroid polyp 3 (%18.7), leiyomyoma 2 (%12.5), lipoma 2 (%12.5), neuroendocrine tumour 1 (%6.3), foveolar epihtelium hyperplasia 3 (%18.7), lymphangiectasia 1 (%6.3), maltoma 1 (%6.3). There were no complications developed during EMR applications using saline solution-assisted and snare technique however endoscopy required bleeding developed in 1 patient during EMR applications using esophageal band ligation. Questioning patient revealed aspirin usage. Conclusions: EMR using adrenaline or band ligation is effective technique with low complication ratio in diagnosis and treatmentof GSL’s smaller than 2cm diameter.
