- While presurgical eating behaviors have demonstrated limited prognostic value, cognitions regarding the effects of eating may serve as important predictors of weight loss outcomes after bariatric surgery. The Eating Expectancies Inventory (EEI) is a commonly used, self-report measure of expected consequences of eating; however, its psychometric and predictive properties have not yet been evaluated among bariatric surgery patients.
- Diabetes is an epidemic disease and is estimated to affect >300 million people worldwide in 2025 . Type 2 diabetes (T2D) management is a combination of diet, lifestyle modifications, and drug therapy. Recently, many studies have shown remission of T2D in obese population [2–6]. Buchwald et al.  in his systemic review and meta-analysis showed that diabetes remission rates were 99% (95% confidence interval, 97%–100%) after biliopancreatic diversion, 84% (95% confidence interval, 77%–90%) after Roux-en-Y gastric bypass (RYGB), and 48% (95% confidence interval, 29%–67%) after gastric banding.
- Obesity is the major trigger of nonalcoholic fatty liver disease (NAFLD). NAFLD is further favored by the patatin-like phospholipase domain-containing 3 (PNPLA3) p.I148M, transmembrane 6 superfamily member 2 (TM6SF2) p.E167K, and membrane-bound O-acyltransferase domain containing 7 (MBOAT7) rs641738 variants.
- Endoscopic treatment of obesity might be an alternative to surgical treatment or, preoperatively, serve as an auxiliary therapy to surgery in patients at increased surgical risk.
- The obesity epidemic is steadily increasing worldwide, and high body mass index (BMI) is a major risk factor for cardiovascular diseases, diabetes, hypertension, musculoskeletal disorders, and also some cancers . Diets are generally unsuccessful . Bariatric surgery is today the main treatment for severe obesity . There is a strong interest in finding less invasive methods  and whether that preoperative weight loss improves surgery outcomes  and reduces perioperative complications .
- Laparoscopic gastric imbrication (LGI) helps to promote weight loss by reducing the size of the stomach by plicating the greater curve of the stomach. However, if the stomach is not adequately plicated at the fundus, gastric diverticula occur. In this case the gastric diverticulum became symptomatic (chronic nausea) and necessitated conversion to a laparoscopic sleeve gastrectomy, which resulted in a resolution of the patient’s symptoms.
- Although the published data have clearly related the size of the gastrojejunostomy anastomosis to the subsequent likelihood of a stricture, a correlation between the anastomosis size and postoperative weight loss has not previously been described.
- Bariatric surgery has experienced unprecedented growth in the United States during the last 10 years . Compared with the late 1980s and early 1990s, when approximately 15,000 bariatric operations were performed each year, in 2003 more than 100,000 bariatric operations were performed in the United States. This growth in bariatric surgery, the fastest-growing major operation in the United States, can be explained by 3 factors: (1) the 4-decades-old epidemic of obesity, (2) steadily improving outcomes for several bariatric operations, and (3) the introduction of laparoscopic bariatric surgery with improved perioperative outcomes.
