Professor Shikora, moderated by Ahmad Bashir, talks about the importance of publication for the dissemination of medical knowledge and for your personal academic career. He reviews the steps to take follow in order to improve the chances for a paper to be accepted for publishing. Rejection rates are high, specially for journals with a high submission rate, and even good papers may be rejected. Fresh, new or interesting material is needed and good English grammar is mandatory. Results and conclusion must be consistent. Original contributions and review articles have the best chance of being of interest for journals. Other categories include brief communications, letters to the editor, case reports, and new concepts. The structure of a manuscript must be respected and each journal has specific guidelines. The “hook” is the abstract and it should be succinct and organized, in order to avoid immediate rejection. The main parts of a manuscript should be the introduction, the methods, the results, the discussion, and the conclusion. Professor Shikora goes through all these questions and gives his advice based on his experience as chief editor for Obesity Surgery. He also gives examples of papers that would be rejected and goes through the reasons why. It is highly recommended that a mentor or senior review the manuscript before submitting it. Following the journal’s instructions is mandatory. After the presentation, there is a debate with the panel members (Ali Aminian, Abdelrahman Nimeri, Alan Saber) and the audience following a short quiz: - Have you ever submitted a paper for publication before? - Have you ever been rejected? - Did the rejection make you stop from submitting the paper again? - Did you revise the paper and then had it be accepted for publication?

IFSO 2018 in Dubai brought together world leaders in metabolic and bariatric surgery. More than 1200 abstracts from more than 90 countries were presented. Several communications on obesity and metabolic surgery were given, focusing on the different techniques and the best indications for each of them. Type 2 Diabetes Mellitus control, postoperative complications reduction and comparison of weight loss in different procedures were some of the main topics discussed during the congress. This webinar summarises the highlights of the 23rd IFSO World Congress in Dubai. Asim Shabbir, Ali AMiniam, Ahmad Bashir, Alex Escalona and Bart van Wagensveld present and discuss about 30 of the best abstracts. They also present 9 Randomized Clinical Trials, 10 Registry studies, 3 Matched case control studies, 4 Non matched controlled studies, and 3 other studies. In the first abstract, R. Gadiot found that after a 1-year follow-up, there was no significant difference in weight loss between the Very long Roux limb -RYGB and the standard limb -RYGB groupds. There were no differences regarding deficiencies either. Similar results were found in other abstracts in 2016. The experts agree that with longer follow-ups, the differences between the two groups should be significant in terms of weight loss and nutritional deficiencies. The study by Ruiz de Gordezuela compares SADI-S vs Duodenal Switch. In this comparison there were no significant differences, except as regards surgical time. However, the Duodenal Switch shows better weight loss results after 3 years (BMI reduction of 46.95% vs 36.61%). J.Ruiz-Tovar’s group showed the Impact of implementation of ERAS on Large Roux in Y Gastric Bypass (LRYGB). It associates lower postoperative pain, lower incidence of postoperative nausea and vomiting, and earlier hospital discharge. Another group shows that weight loss 3 months after the primary bariatric surgery is predictive for weight loss up to 60 months, giving us the opportunity to select low responder patients. In this video you will see the entire discussion on these abstracts and the opinion of the experts in the 23rd IFSO World Congress.

Up to 60% of bariatric patients present with gastroesophageal reflux disease (GERD) and approximately 20% will develop de novo GERD after bariatric surgery, particularly after a sleeve gastrectomy. Esofago-gastric reflux after a sleeve gastrectomy is caused by several factors: injury to the lower esophageal sphincter, obstructive sleeve (long and narrow tube with high intraluminal pressure), dilatation of the upper part of the sleeve, and hiatal hernia with intra-thoracic migration of the gastric tube. Several treatment regimes have been proposed for treatment of reflux after sleeve, from medical therapy to surgical revision. In this IFSO Online Symposium, Camilo Boza and Chih-Kun Huang present the cases and treatments of patients with reflux after sleeve gastrectomy. An interesting discussion on the most appropriate treatment by a panel of IFSO experts follows.
