Does Patient Compliance with Follow-up Influence Weight Loss After Gastric Bypass Surgery? A Systematic Review and Meta-Analysis

Abstract

Gastric bypass surgery is an effective intervention to manage morbid obesity. However, there have been suggestions that patients who do not comply to follow-up lose less weight. This study evaluated the influence of patient's follow-up compliance on weight loss post gastric bypass surgery. From the search of MEDLINE and EMBASE, four studies (n = 365) were identified and majority of these studies concluded that compliance with follow-up leads to increased weight loss. Our meta-analysis of these studies found increase in the percentage of excess weight loss (%EWL) at 1-year post gastric bypass surgery (mean difference 6.38 % %EWL, 95 % CI 1.68-11.15) when patients were compliant with follow-up. Therefore, this review found that continued long-term follow up of gastric bypass patients has the potential to increase postoperative weight loss.

Bioelectrical Impedance Analysis Results for Estimating Body Composition Are Associated with Glucose Metabolism Following Laparoscopic Sleeve Gastrectomy in Obese Japanese Patients

“…%TBWL was 31.7 ± 8.5% and %EBWL was 79.6 ± 28.9% at 12 months compared to pre-surgery weights. The results are similar to previous studies [ 17 , 18 , 19 ]. In addition, several studies described the data in Japanese patients following bariatric surgery [ 20 , 21 ].…”

“…In terms of weight loss, a sustained reduction of ≥50% excess weight is considered as a success. Recent meta-analyses and systematic reviews have reported a %EBWL close to 60% one year after a gastric bypass with ranges from 33% to 77% [ 17 , 18 , 19 ]. In the present study, LSG reduced BW in all time periods observed.…”

Long-term follow-up after bariatric surgery in a national cohort

“…Difficulty in achieving lifelong follow‐up after bariatric surgery may also influence the various outcomes and can even be responsible for serious medical complications. It has been established that effective adherence to postoperative follow‐up may have positive effects on weight loss. Late surgical complications may occur during the early years following bariatric surgery and micronutrient deficiency is one of the main long‐term medical adverse effects, especially after malabsorptive procedures.…”

Nutritional monitoring of patients post‐bariatric surgery: implications for smartphone applications

“…The present study confirmed that there is a low uptake of currently available bariatric apps and also that there is no single, routinely recommended mHealth app among dietitians. Further exploration into apps for these populations is justified because other research has focussed on discrete aspects such as app use in dietetics (18,22,24,25) , apps for bariatric patients (16,17) and reasons for bariatric patients becoming lost to follow-up (9,23,26) .…”
