Obesity-Associated Disorders Before and After Weight Reduction by Vertical Banded Gastroplasty in Morbidly vs Super Obese Individuals

Sleeve Gastrectomy—A “Food Limiting” Operation

“…However, there are differences between SG and the traditional representatives of the restrictive procedures (vertical banded gastroplasty and adjustable gastric banding), as we have previously reported [14]. In order to achieve energy intake reduction, which will result in acceptable weight loss, the pouch volume for both restrictive procedures has to be tiny and not exceed 15 cm 3 [23]. In SG, food intake is not restricted by the introduction of foreign material.…”

The Effect of Loss of Excess Weight on the Metabolic Risk Factors after Bariatric Surgery in Morbidly and Super-Obese Patients

“…In addition, SO patients needed significantly longer to reach the defined steps of EWL than MO patients, a fact also observed by other groups. 17,19,20 Many studies have measured success of obesity surgery in EWL, without consideration of the obesity-related metabolic disorders. 17,34 On the other hand, there have been discussions on how much weight patients need to lose to resolve their metabolic disturbances.…”

“…18 Only two studies, however, have compared the course of different metabolic parameters during excess weight loss after restrictive surgery between MO and SO patients. 17,19,20 Because it is known that there are gender differences concerning the metabolic risk factors and their course during weight loss, some studies have looked into these factors, with separation of their cohort by gender or looking only into female groups. 17,[21][22][23][24] In this study, the metabolic parameters before bariatric surgery and postoperatively at distinct stages of EWL (25%, 50% and 75%) were studied.…”

Obesity surgery: Evidence-based guidelines of the European Association for Endoscopic Surgery (EAES)

“…Other groups use the Epworth sleepiness scale or similar instruments to screen for patients who will require polysomnography (EL 4 [299]). Various studies have found a higher preoperative prevalence of pulmonary problems with increasing BMI (EL 2b [214]). One study, however, failed to confirm the predictive value of both, BMI and Epworth sleepiness scale, in the prediction of obstructive breathing disorders (EL 2b [109]).…”
