Background/Aims: Acute pancreatitis (AP) runs a moderately severe and severe course in 20%-30% of cases. The purpose of the present study was to determine the effect of low molecular weight heparin (LMWH) for the prevention of pancreatic necrosis (PN) in moderately severe and severe AP (MSAP). Materials and Methods: A total of 100 patients with MSAP were randomized to receive either standard care (SC) or SC plus LMWH. LMWH was administered at 1 mg/kg via subcutaneous injection twice a day between days 1 and 7. The revised Atlanta criteria were used in the diagnosis of MSAP. Patients with a Harmless AP Score of ≥1 and a Balthazar computed tomography (CT) score of D and E were included in the study. Results: The mean age±SD of the patients (46 male and 54 female) was 52±19 years (range, 17-100). There were 50 patients in each group. On admission, clinical and laboratory parameters and Balthazar CT scores were similar between the groups. Initially, PN was present in one patient in the LMWH group and two in the SC group. Over the course, PN developed in 3 (6.1%) patients in the LMWH group and 11 (22.9%) in the SC group (p<0.05). Local and systemic complications were significantly lower in the LMWH group (p<0.05). No hemorrhagic complication occurred. Mortality was not significantly different between the groups (p=0.056). Conclusion: Low molecular weight heparin treatment is safe and provides better prognosis in MSAP. Cite this article as: Tozlu M, Kayar Y, İnce AT, Baysal B, Şentürk H.

Background/Aims: Pathogenesis of functional dyspepsia (FD) is unclear and not well documented. Some gastric motility abnormalities have been reported to be important factors. Transcutaneous electrogastrography (EGG) is an experimental method that is used to assess FD. We aimed to compare FD patients with control subjects in terms of motility abnormalities according to the EGG results. Materials and Methods: Thirty patients with FD and thirty control subjects were included. EGG was preprandially and postprandially performed. The recordings were analyzed and compared between the two groups. Results: Mean ages of the cases and controls were 31.4±9.3 and 32.58±7.6 years, respectively. Female subjects constituted 80% of the FD group and 76.67% of the control group. In terms of the preprandial dominant frequency (DF), the FD group demonstrated lower incidence of normal subjects than the control group [13 (43.3%) and 22 (73.3%), respectively] and a higher incidence of bradygastria than the control group [17 (56.7%) and 8 (26.6%), respectively]. In the FD group, the rate of cases with normal postprandial DF was lower than that in the control group [10 (33.3%) and 23 (76.7%), respectively], whereas the rates of bradygastria [18 (60%) and 7 (23.3%), respectively] and tachygastria [2 (6.7%) and 0 (0%), respectively] were higher in the FD group (p<0.05). Preprandial and postprandial DF values were statistically significant in both groups. Conclusion: A high incidence of gastric motility and myoelectrical activity abnormalities was observed in patients with FD. EGG is an effective, reliable, and non-invasive method in differentiating the subgroups. After standardization of some parameters, EGG may be an essential and irreplaceable test to diagnose and follow-up FD patients with motor dysfunction.

Background and Objectives: Although there are many studies that investigate the relationship between duodenogastric reflux (DGR) and Helicobacter pylori in adult patients, the reported data are contradictory. In addition, there are very few studies in the literature investigating the relationship between DGR and H. pylori in the pediatric age group. In the present study, we investigated the effect of primary DGR on H. pylori and gastritis. Materials and Methods: A total of 361 patients who were referred to the clinic of our hospital with dyspeptic complaints who had an upper gastrointestinal system endoscopy and a gastric biopsy were included in the study. Results: DGR was detected in 45 cases, and 316 cases that did not have DGR were considered as the control group. Comparisons were made between the DGR cases and the control group in terms of risk factors (age, gender), the presence and density of H. pylori, and the presence and severity of gastritis. The average age of the patients who were included in the study was 11.6 ± 4.6 years. A total of 128 (36%) of the cases were male and 233 (64%) were female. DGR was present in 45 (13%) of the cases. The average age of the patients with DGR was 13.9 ± 3.1 years, the average age of the control group was 11.3 ± 4.7, and there were statistically significant differences (p < 0.001). No significant differences were detected in terms of gender between DGR and the control group (p > 0.05). H. pylori (+) was detected in 29 (64%) of patients with DGR, and in 202 (64%) of the control group. No significant differences were detected between H. pylori prevalence (p = 0.947). Gastritis was detected in 37 (82%) of the patients with DGR, and in 245 (77%) of the control group (p = 0.476). No significant differences were detected between the presence and density of H. pylori, gastritis presence, severity and DGR (p > 0.05). Conclusions: The ages of patients with DGR were significantly higher than in the control group, and advanced age was shown to be a risk factor for primary DGR. It was found that the presence of DGR has no effect on the presence and severity of H. pylori. Given this situation, we consider it is important to eradicate H. pylori infection, especially in the case where H. pylori is present together with DGR.

Background: Crohn disease is a chronic bowel disease that causes serious complications. Prevalence of Crohn disease is increasing. Studies have shown that the behavior of the disease is not stable and severe complications secondary to behavior change over time have been shown. In this study, we aimed to evaluate the prognostic risk factors associated with phenotypic change in Crohn disease in a Turkish patient cohort. Methods: Patients followed up from March 1986 to August 2011 were evaluated for demographic and clinical characteristics to determine possible risk factors and initial clinical phenotype of the disease based on the Montreal classification. The cumulative probabilities of developing stricturing or penetrating intestinal complications were estimated using the Kaplan-Meier analysis. Univariate and multivariate Cox-proportional hazard models were used to assess associations between baseline clinical characteristics and intestinal complications. Results: Three hundred and thirty patients (mean age, 30.6 ± 11.1 years; 148 female) were included in the study. Mean follow-up duration was 7.4 ± 5.3 years (range: 1.0–25.0 years). At baseline 273 patients had inflammatory-type disease, 57 patients experienced stricturing/penetrating intestinal complications before or at the time of diagnosis. The cumulative probability of developing complicated disease was 37.4% at 5 years, 54.3% at 10 years, 78.8% at 25 years. Independent predictors associated with progression to intestinal complications were current smoking, perianal disease, extra-intestinal manifestations, and location of disease. Conclusions: Location of disease is the most powerful indicator for the development of stenosis and penetrating complications in inflammatory-type disease. Patients with ileal involvement should be considered for more aggressive immunosuppressive therapy.
