“…Compared with RYGB, LAGB has a higher risk of slip/dilation and surgical reversal/conversion, but a lower risk of stricture, ulceration, and hernia compared with RYGB ( 39 ). LAGB has a shorter duration of stay compared to RYGB; SG has a higher risk of reoperation compared to RYGB ( 40 ). Compared with RYGB, SG and LAGB are associated with a higher failure rate or secondary surgery, which may be the main reason for the current high clinical use of RYGB.…”

BackgroundObesity is one of the most important public health conditions in the world, and surgical intervention is the only medical treatment recognized by the medical community as a complete and permanent cure for morbid obesity and its complications. The choice of surgical modality is also based more on the experience of the physician or the requirements of people with obesity, rather than on scientific data. In this issue, a thorough comparison of the nutritional deficiencies caused by the three most commonly used surgical modalities is needed.ObjectivesWe aimed to use the network meta-analysis to compare the nutritional deficiencies caused by the three most common BS procedures in many subjects who underwent BS to help physicians determine the best BS surgical approach to apply to their clinical people with obesity.SettingA systematic review and network meta-analysis of world literature.MethodsWe followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses, systematically reviewed the literature, and conducted a network meta-analysis using R Studio.ResultsFor the four vitamins calcium, vitamin B12, iron and vitamin D, the micronutrient deficiency caused by RYGB is the most serious.ConclusionsRYGB causes slightly higher nutritional deficiencies in Bariatric surgery, but RYGB remains the most commonly used modality for Bariatric surgery.Systematic Review Registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42022351956, identifier: CRD42022351956.

Background: Obesity has an adverse impact on metabolic parameters including CKD. Bariatric procedures produce significant weight loss compared to non-surgical means and have a positive effect on renal and non-renal parameters. The present study retrospectively evaluated the effect of bariatric procedures and weight loss on renal function, proteinuria, hypertension, lipid profile and diabetic status in chronic kidney disease (CKD) patients in Queensland, Australia. Methods: Of the 880 patients who consented to the CKD Registry, data of patients who underwent bariatric procedures were analysed. Changes in anthropometric measures, renal functions, lipid profile, glycosylated haemoglobin A 1c (HbA 1c ) (%), proteinuria and requirement for blood pressure medications and insulin dose were noted during followup. Results: Eight patients (1%) (mean age 48 years: there were 5 men) underwent bariatric procedures (gastric banding -four, gastric sleeve -three and gastric bypass -one). Mean follow-up duration was 10 years. During follow-up a trend towards reduction was noted in weight (kg) (163 -115 p = 0.01), proteinuria (g/mol) (381 -65 p = 0.302), HbA 1c (%) (8.1 to 6.7 p = 0.03) and total cholesterol (mmol/L) (4.7 to 4.0 p = 0.33). The estimated glomerular filtration rate (eGFR) (mL/min/1.73m2 ) did not change significantly (58.1 -54.1 p = 0.426). Reductions of anti-hypertensive medications (1.8 -0.75, p = 0.08) and insulin dose (IU) (61.3 -25 p = 0.37) were also noted. One patient developed complications requiring removal of the gastric band. One patient progressed to end-stage renal disease. Conclusions: There was significant weight loss leading to improvement in multiple metabolic parameters. There was a trend towards a slow progression of CKD post-bariatric surgery during the follow-up. Although the numbers are small bariatric procedures appears to have a significant role in the management of obesity associated with CKD and related metabolic conditions.

Bone Structural Changes and Estimated Strength After Gastric Bypass Surgery Evaluated by HR-pQCT

et al. 2015

Roux-en-Y gastric bypass surgery (RYGB) is an effective treatment of morbid obesity, with positive effects on obesity-related complications. The treatment is associated with bone loss, which in turn might increase fracture risk. The aim of this study was to evaluate changes in bone mineral density (BMD) and bone architecture assessed using dual-energy X-ray absorptiometry (DXA) and high-resolution peripheral quantitative computed tomography (HR-pQCT), 6 and 12 months after RYGB, and correlate them to changes in selected biochemical markers. A prospective cohort study included 25 morbidly obese patients (10 males, 15 females). Patients were examined with DXA of the hip and spine, HR-pQCT of radius and tibia, and blood sampling before and 6 and 12 months after RYGB. Patients lost in average 33.5 ± 12.1 kg (25.8 ± 8.5 %) in 12 months. In tibia, we found significant loss of total, cortical and trabecular volumetric BMD after 12 months (all p < 0.001). Microarchitectural changes involved lower trabecular number, increased trabecular separation, and network inhomogeneity along with thinning of the cortex. Estimated bone failure load was decreased after 12 months (p = 0.005). We found only minor changes in radius. Results demonstrate significant alterations of bone microarchitecture suggesting an accelerated endosteal resorption along with disintegration of the trabecular structure which resulted in a loss of estimated bone strength in tibia. Such changes may underlie the recently reported increased risk of fracture in bariatric patients after surgery. We only observed bone structural changes in the weight-bearing bone, which indicates that mechanical un-loading is the primary mediator.
