“…We failed to find correlations between preoperative BMI/ weight and weight loss after surgery, in line with some studies [16][17][18][19], but contrarily to others reporting a negative association between baseline BMI, waist circumference, waist-to-height ratio and post-BS weight loss at different follow-up times [3,6,9,11,15,17,20,29]. Indeed, weight and BMI are both inaccurate measures of body composition with respect to fat distribution [48].…”

“…The role of age in influencing post-BS weight loss is still controversial. Older age has been associated with lower weight loss at 6 months [3,4,11], 12 months [4,6,17,19] and 24 months [4] after surgery by many, but not all studies [9,15,16,18,[20][21][22]. We found a strong direct relationship between age and BS unsuccess at 24 months: the risk of unsuccess almost doubled with every increase in decade of age.…”

“…Differences among studies might be due to differences in mean ages of cohorts, ranging from 34 [10] to 45 years [21], ethnicity [4,17,19], and employed surgical techniques. The reduced weight loss might be explained by decreased age-related resting energy expenditure (REE) due to: reduction in fat-free mass [25]; presence of adaptive thermogenic processes [26] or lower capacity to metabolize substrates [27]; the increased prevalence of comorbidity [28]; the reduction in exercise [29] and lower compliance to the received lifestyle recommendations [20]. Among our patients, the most powerful predictor of weight loss both at 12 and 24 months was %EWL at 6 months.…”

“…On the other hand, associations between pre-bariatric BMI and weight loss after BS have been shown highly contrasting, since either inverse [3,13,14], direct [4,15] or no [16][17][18][19] relationships have been reported. Similarly, sex and age have been correlated with weight loss in some studies [4], but not in others [20] and the presence of personality disorders, psychiatric diseases, eating disorders or stressful life events (such as binge eating, sweet eating, depression, anxiety, low self-esteem, alcohol abuse, previous sexual abuse) have resulted both predictive [21] and not predictive [22] of poor BS success. Furthermore, studies presented great heterogeneity with respect to follow-up durations (from 6 months [3] to 7 years [4]), sample size (from 20 patients [18] to about 1300 [20]), type of surgery (intragastric balloon (IGB) [3], LAGB [19], GBP [6], SG [4] or biliopancreatic diversion [23]), and age and ethnic characteristics of participants [2,4,19].…”
Purpose Bariatric surgery (BS) has been recognized as an effective treatment for most patients with morbid obesity, but a variable range of patients failed to achieve a successful weight-loss. Controversial data are available about predictors of unsuccess. We aimed to retrospectively assess whether clinical baseline characteristics of patients submitted to sleeve gastrectomy (SL) or gastric bypass (GBP) were associated with unsuccessful weight-loss after 12 and 24-month follow-up. Methods Three hundred patients who underwent BS from the 1st January 2016, with at least 24-months follow-up, were enrolled. Patients were divided according to their percentage of excess weight-loss (%EWL) either < 50% or ≥ 50% after 12 and 24-month follow-up. Results None of the patients was lost at follow-up; 56 (18.7%) patients showed a %EWL < 50% at 24 months. Age, neck circumference, obstructive sleep apnea (OSA) were significantly higher, while total cholesterol and %EWL 6-months lower in those with %EWL < 50% at 12-months. Age, neck circumference, male and OSA rates were increased, while %EWL at 6-months lower in patients with %EWL < 50% at 24-months. In a multiple regression model, age (OR = 1.076; 95% CI 1.

“…Weight regain is mainly due to gastric pouch dilatation, which consists of an abnormal ectasia of the gastric lumen, is detected via CT scan following oral contrast administration; 3D multiplanar measurements and reconstructions are useful for evaluation of the morphology and anatomical relationships of the stomach with other abdominal organs ( Figure 6 ) [ 15 ]. Figure 6 Gastric pouch dilatation in a 42-year-old woman with weight regain 5 years after MGB/OAGB surgery.…”
Obesity is a widespread pathology among the population related to an increase in mortality and morbidity of patients. Bariatric surgery provides several forms of treatment for obese patients. Laparoscopic mini/one anastomosis gastric bypass (MGB/OAGB) is a recent low risk bariatric surgical procedure common in a large number of countries in the treatment of severe obesity. MGB/OAGB, compared to other bariatric surgery techniques, offers the significant technical improvement of requiring only one anastomosis in place of two. In this scenario, diagnostic imaging takes a significant role in the postoperative period, to evaluate the outcomes of surgical treatment and to detect possible complications both in early and late postoperative period. The prevalent radiological procedure to investigate suspicions of clinical post-operative complications is Computed tomography (CT) with oral and intravenous contrast administration. This pictorial essay aims to illustrate and identify normal radiological aspects of MGB/OAGB and post-surgery complication imaging features. We think that this article will serve to familiarize all the specialists with the diagnostic imaging of MGB/OAGB.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
