[\/vc_column_text][\/vc_column][vc_column width=”1\/4″][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text css=””]Over the past 36 years, my early research, sponsored by the German Research Society, covered areas of gastric and pancreatic physiology and gastrointestinal hormones. A highlight during my postdoctoral fellowship (1981 to 1983) at CURE\/UCLA with John Walsh, MD, was the discovery of Cholecystokinin-58 (together with Joseph R. Reeve, PhD) which is the major form in the intestine in humans and many animals expressing the biological activity of Cholecystokinin (Peptides 3:687-691, 1982, Proceedings of the National Academy of Sciences 81(2):6565-6568, 1984, Journal of Biological Chemistry 261:16392-16397, 1986). After finishing my training in Gastroenterology in Germany I came in 1988 as Associate Professor to Harbor-UCLA. I joined as GI faculty the NIH funded IBD Center at Harbor-UCLA where I was the Director of the Biochemistry Core. I was especially interested in the role of growth factors in protecting and healing the mucosa in experimental colitis models. This research was also supported by the Crohn\u2019s and Colitis foundation. After funding ended I focused on clinical research in advanced endoscopy and endosonography. I started endosonography at Harbor-UCLA Medical Center, being the first in the LA area. Areas of interest are eradication of Barrett\u2019s esophagus with dysplasia, endoscopic and submucosal mucosal resections, endoscopic fundoplications (Transoral Incisonless Fundoplication, TIF), metal stent placements and pancreatic and biliary diseases, e.g. drainage of walled off pancreatic necrosis. Recently, a main focus is the improvement of the diagnostic yield of endosonography guided fine needle aspirations (FNA) of cystic and solid pancreatic neoplasms by chromosomal analyses and the development of new FNA techniques. Harbor-UCLA Medical Center has developed into a referral center for advanced endoscopy with a focus on pancreatic, biliary and intestinal diseases. We have developed a successful 4th year GI fellowship program in advanced endoscopy and endosonography supporting the mission of our endoscopy center.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_tta_accordion][vc_tta_section title=”Publications” tab_id=”1766384550460-77f55b2a-1133″][vc_column_text css=””]Publications which I consider to have significantly advanced the field of endoscopy:<\/strong><\/p>\n

    Diagnosis of cystic and solid neoplasms of the pancreas and bile duct malignancies.<\/strong><\/p>\n

    Cystic neoplasm of the pancreas such as mucinous cysts and side-branch intraductal papillary mucinous neoplasms are a major challenge regarding diagnosis and management since they have malignant potential.\u00a0 In the past CEA and amylase levels in cyst aspirates obtained by endosonography (EUS) guided fine needle aspirations were used to differentiate cystic neoplasms of the pancreas from benign serous cysts.\u00a0 However, there are many cysts that are indeterminate.\u00a0 The determination of KRAS, GNAS and allelic imbalances of tumor suppressor genes in cyst aspirates in addition to the endosonography features allowed us to predict the benign biological behavior of the cysts avoiding high risk surgeries.<\/p>\n

    Endosonography guided fine needle aspirations of solid pancreatic neoplasms often (up to 30%) yield inconclusive results showing on pathology only atypical cells which could be seen in inflammatory conditions but also in neoplasms.\u00a0\u00a0 We were among the first groups to show that immuno-histochemical analyses significantly increase the diagnostic yield EUS-guided fine needle aspirations (FNA) of pancreatic masses. We further showed that the diagnostic yield of pancreatic EUS-FNA is markedly improved by performing FISH analysis for chromosomal abnormalities and KRAS mutational profiling.<\/p>\n

    Improving the diagnostic yield of endoscopic sampling techniques is a major issue also in biliary diseases, as the early and efficient malignancy diagnosis, circumventing the need for repeat procedures, is critical for patients\u2019 care and, ultimately, survival. We were among the first groups to show that immunohistochemical analyses significantly increase the diagnostic yield of biliary strictures.<\/p>\n

      Endoscopic treatment of gastroesophageal reflux disease and Barrett\u2019s esophagus.<\/strong><\/p>\n

      Acid reflux into the esophagus causes Barrett\u2019s esophagus which can lead dysplasia and finally to esophageal carcinoma.\u00a0 We could show that dysplasia in\u00a0Barrett\u2019s esophagus<\/strong>\u00a0could be successfully eradicated by\u00a0radiofrequency ablation<\/strong>\u00a0with or without additional endoscopic mucosal resection avoiding high risk surgeries.<\/p>\n

      Severe gastroesophageal reflux disease causing regurgitation can be treated by surgery (Nissen fundoplication) if antisecretory treatments fail.\u00a0 Nissen fundoplication can however have in up to 20% severe side effects such as new onset of dysphagia and the inability to belch.\u00a0 Endoscopic fundoplication without incision (Transoral Incisionless Fundoplication, TIF<\/strong>) does not have these side effects.\u00a0 We have performed successfully without complications over 120 TIF procedures with or without laparoscopic hernia repair (a surgical procedure which does not cause dysphagia or inability to belch).\u00a0 The data are very promising and have been published.<\/p>\n

        New endoscopic interventional techniques.<\/strong><\/p>\n

        Advanced endoscopy and endosonography are main areas of my clinical research.\u00a0\u00a0 We could show that<\/p>\n

        long term stenting using fully covered metal stents for benign bile duct strictures could relief the obstruction in the majority of patients avoiding high risk surgeries. This technique was also used with high success for recalcitrant bile duct leaks.<\/p>\n

        Fully covered metal stents could also successfully used in the palliation of malignant gastrointestinal obstructions bridging or avoiding surgery. This was also part of a Multi-Center study.<\/p>\n

        Another project focuses on the use of fully covered metal stents in management benign refractory esophageal strictures. This project was part of a multi-center trial where I was co-investigator.<\/p>\n
