Abstract ID: 1604. Pancreatic function as evaluated by the 13C-MTG breath test in patients after bariatric surgery o-Noia, Laura Nieto-Garcia, Julio Laura Uribarri-Gonzalez, Jos e Larin oz Iglesias-Garcia, J. Enrique Domínguez-Mun Department of Gastroenterology and Health Research Institute of Santiago (IDIS), University Hospital of Santiago, Spain Introduction: Gastric and duodenal anatomical changes secondary to bariatric surgery lead to important disturbances in the digestion/absorption process. These digestive disturbances may be evaluated by the 13 CMTG breath test. Aims: Aim of our study was to evaluate the pancreatic and digestive function after different bariatric surgical procedures Materials & methods: A prospective, cross sectional study was performed. Pancreatic function was evaluated in patients who underwent a bariatric surgical procedure by the 13 C-MTG breath test. The cumulative 13 CO2 recovery rate (CRR %), time to 13C exhalation peak and dynamic of 13 CO2 exhalation (% digestion from 0-2, 2-4 and 4-6 hours after meal) were evaluated. Data are shown as median and interquartile range and analysed by the Kruskal Wallis and U-Mann Whitney tests. Results: 94 patients were included (35 patients duodenal switch, 36 gastric bypass, 23 gastric sleeve). Pancreatic function was lower after duodenal switch CRR 29.02% ± (21.19) than after gastric bypass 43.75%±(9.02) or gastric sleeve 49.05%±(14.04) (p<0.01). 13C- exhalation peak occurred at 330min 7.13%±(4.03), 150min 9.14%±(3.96) and 105min 12.06%±(2.32) min after duodenal switch, gastric bypass and gastric sleeve, respectively. Nutrients are digested late (4-6 hours after meal) after duodenal switch, intermediate after gastric bypass (2-4 hours) and early after gastric sleeve (0-2 hours) (p<0,01). Conclusion: Significant pathophysiological changes in digestive/absorption process according to particular bariatric surgery procedure are described. Duodenal switch alters digestive process more than any other procedure. Compared to gastric bypass, gastric sleeve does not seem to affect pancreatic function significantly.
Abstract ID: 1630. Introduction: Studies suggest an association between tooth loss and periodontal disease with an increased risk of pancreatic ductal adenocarcinoma (PDAC). However, controversial results have been recently reported. In addition, the association between other oral health problems and this cancer has not yet been investigated. Aims: To explore the association between different oral health conditions and PDAC risk. Patients & methods: Detailed information about oral health was reported for 1,413 cases and 733 controls in the PanGenEU study. Associations between PDAC and halitosis, teeth sensitivity, moving teeth, periodontitis, tooth loss, and gum bleeding, inflammation, and recession were explored through multivariate logistic regression analysis. Interactions with age, sex, smoking, diabetes and asthma were evaluated. Results: Periodontitis and tooth loss were not significantly associated with PDAC risk (OR¼ 1, 95%CI 0.76-1.34; OR for >17 tooth loss¼ 0.93, 95%CI 0.63-1.37). A significant association between gum recession and PDAC was observed among asthmatics but not among non-asthmatics (OR¼ 4.56 95% CI 1.74-11.9, OR¼ 1.06 95%CI 0.83-1.34; respectively, p-value for interaction¼ 0.02). Significant effect modification was observed between having moving teeth and smoking, age, and diabetes (p< 0.03). No other significant associations or interactions were observed. Conclusion: Oral health characteristics were not significantly associated with PDAC risk in the general models. Effect modifications for some of the explored associations point to their complex relationship and highlight the importance of further inquiry in future studies. Biological and/or
Quarter century experience of pancreatic surgery in a high volume center e A SWOT analysis of 2787 consecutive pancreatic resections €us Felsenstein 1, Timm Fritz Klein 1, Uwe Pelzer 2, Hanno Riess 2, Mattha 3 1 1 Denecke , Johann Pratschke , Marcus Bahra 1 Universita €tsmedizin Berlin, Department of General, Visceral Charite and Transplantation Surgery, Germany 2 Universita €tsmedizin Berlin, Department of Hematology and Charite Oncology, Germany 3 Universita €tsmedizin Berlin, Department of Diagnostic and Charite Interventional Radiology, Germany
Introduction: Pancreatic surgery has undergone major changes over the last decades. While the complexity of indications has increased the overall surgical complications could continuously be reduced. All the more, the quality of surgery remains to be considered as one important factor for achieving long-term survival especially in patients at advanced stages of disease. Aims: The authors reviewed the surgical outcome, pathological findings and long-term follow-up in a consecutive group of 2787 patients undergoing pancreatic resections in a high volume center. Patients & methods: Between january 1990 and september 2015 an overall of 2787 patients underwent pancreatic resection at our institution. The data of all patients were recorded in a prospective database. A retrospective SWOT analysis of all relevant parameters was performed.
