Metabolic/Bariatric Surgery Worldwide 2011

Abstract: Background Metabolic/bariatric procedures for the treatment of morbid obesity, as well as for type 2 diabetes, are among the most commonly performed gastrointestinal operations today, justifying periodic assessment of the numerical status of metabolic/bariatric surgery and its relative distribution of procedures.

Bariatric Surgery Worldwide 2013.

Abstract: The first global survey of bariatric/metabolic surgery based on data from the nations or national groupings of the International Federation for the Surgery of Obesity and Metabolic Diseases (IFSO) was published in 1998, followed by reports in 2003, 2009, 2011, and 2012. In this survey, we report a global overview of worldwide bariatric surgery in 2013. A questionnaire evaluating the number and the type of bariatric procedure performed in 2013 was emailed to all members of bariatric societies belonging to IFSO. Trend analyses from 2003 to 2013 were also performed. There were 49/54 (90.7 %) responders; 37 of the 49 with national registries. The total number of bariatric procedures performed worldwide in 2013 was 468,609, 95.7 % carried out laparoscopically. The highest number (n = 154,276) was from the USA/Canada region. The most commonly performed procedure in the world was Roux-en-Y gastric bypass (RYGB), 45 %; followed by sleeve gastrectomy (SG), 37 %; and adjustable gastric banding (AGB), 10 %. Most significant were the rise in prevalence of SG from 0 to 37 % of the world total from 2003 to 2013, and the fall in AGB of 68 % from its peak in 2008 to 2013. SG is currently the most frequently performed procedure in the USA/Canada and in the Asia/Pacific regions, and second to RYGB in the Europe and Latin/South America regions. The accuracy of the IFSO-based world survey of procedures would be enhanced if each nation or national group would create a national registry.

Biliopancreatic Diversion with a Duodenal Switch

Abstract: Background: This paper evaluates biliopancreatic diversion combined with the duodenal switch, forming a hybrid procedure which is a combination of restriction and malabsorption. Methods: The evaluation is of the first 440 patients undergoing this procedure who had had no previous bariatric surgery. The mean starting weight was 183 kg, with 41% of our patients considered super morbidly obese (BMI > 50). Results: There was an average maximum weight loss of 80% excess weight by 24 months postoperation; this continued at a 70% level for 8 years. Major complications were found in almost 9% of the cases. There were two perioperative deaths, one from pulmonary embolism and one from acute pulmonary obstruction. There were 36 type II diabetics, all of whom have discontinued medication following the surgery. Seventeen revisions were performed to correct excess weight loss and low protein levels. There have been no marginal ulcers, no cases of dumping syndrome, no foreign material used, and the procedure is a pyloric saving procedure which is functionally reversible. Conclusions: This operation has vastly improved the lives of seriously obese patients with many co-morbidities. All type II diabetics have essentially been cured of their disease. The procedure was tolerated well and patients are quite satisfied. There was minimal regain of weight with this method.

The Medical Risks of Obesity

Abstract: Obesity is associated with a number of medical conditions that lead to increased morbidity and increased mortality. Both the National Institutes of Health and the World Health Organization define obesity as a body mass index (BMI) > or = 30 kg/m2 and overweight as a BMI 25-30. The most common conditions associated with obesity are insulin resistance, diabetes mellitus, hypertension, dyslipidemia, cardiovascular disease, gallstones and cholecystitis, sleep apnea and other respiratory dysfunction, and the increased incidence of certain cancers. These are discussed below.

Laparoscopic gastric bypass, Roux-en-Y- 500 patients: technique and results, with 3-60 month follow-up.

Abstract: Background:The authors have performed the laparoscopic gastric bypass since 1993 and perform about one-half of bariatric cases laparoscopically. Since our initial report, several groups throughout the world have preformed the gastric bypass laparoscopically, with various modifications. Method: Prospectively, we followed and recorded the results of our laparoscopic patients. A detailed pre- and post-operative analysis of the patient's co-morbidities is performed as well as complete weight and laboratory data evaluation. Results:With > 80% follow-up, we found an excess weight loss of about 80% by the first year. This degree of loss is well sustained. Over 95% of the significant pre-operative co-morbidities are controlled. Conclusion: The laparoscopic gastric bypass has been refined over 5 years of use. Though we have not changed the basic operation as we originally described, others have modified the various anastomotic techniques. The weight loss results are very good to excellent, with patients now out to "long-term" follow-up. Resolution of the co-morbidities is documented. The operation has an adequate track record to show effectiveness, and training programs should be established to maximize safety.
