Long-Term Results of Sleeve Gastrectomy and Roux-en-Y Gastric Bypass in Individuals Older Than 60 Years with Morbid Obesity.
An increasing Pnumber of individuals with obesity over the age of 60 years require bariatric surgery to treat obesity and its related medical problems. Sleeve gastrectomy and Roux-en-Y gastric bypass have already proven their efficacy in this population, but literature lacks reports of long-term results. The aim of this study is to compare long-term results of sleeve gastrectomy and Roux-en-Y gastric bypass in individuals older than 60 years old.
This is a single-center, retrospective, comparative study of 204 patients undergoing either sleeve gastrectomy (123, 60.3%) or Roux-en-Y gastric bypass (81, 39.7%) for morbid obesity with a mean follow-up of 44.5 ± 19.1 months and 54.6 ± 17.9 months, respectively.
Total weight loss was significantly increased for patients who underwent Roux-en-Y gastric bypass compared to sleeve gastrectomy from 12 to 48 months after surgery, while no significant difference was found after 60 (30.39% vs. 27.63%) and 72 (27.36% vs. 23.61%) months. Roux-en-Y gastric bypass was associated to a significant increased rate of early postoperative complications (22.2% vs. 4%; p < 0.0001), but no difference was found concerning late postoperative morbidity (6.2% vs. 1.6%). Both procedures were effective in obesity related medical problems.
Roux-en-Y gastric bypass confers an increased weight loss than sleeve gastrectomy in patients over the age of 60 in the mid-term, but it is associated with more early postoperative complications. Sleeve gastrectomy can be considered a valid alternative as long-term weight loss results are superposable to those ensured by Roux-en-Y gastric bypass.

Comparative analysis of weight loss and resolution of comorbidities between laparoscopic sleeve gastrectomy and Roux-en-Y gastric bypass: A systematic review and meta-analysis based on 18 studies.
Laparoscopic Roux-en-Y gastric bypass and laparoscopic sleeve gastrectomy are the most common procedures performed in bariatric surgery and both have been demonstrated to have significant effectiveness in treating morbid obesity. However, comparative analysis of their effectiveness has not been well studied. This comparative analysis was conducted to determine whether Laparoscopic Roux-en-Y gastric bypass and laparoscopic sleeve gastrectomy have the same mid- and long-term outcomes in weight loss, resolution of obesity comorbidities and adverse events (AEs) of treatment.
We searched the Cochrane Library, PubMed, Embase and Web of Science databases from the establishment of the database to January 1, 2020 for both randomized control trials and non-randomised interventional studies that studied Laparoscopic Roux-en-Y gastric bypass and laparoscopic sleeve gastrectomy with respect to weight loss outcomes, resolution of obesity comorbidities and AEs of treatment. Standardised mean differences, risk ratios and odds ratio with 95% confidence intervals were calculated to compare the outcomes of the groups. Two reviewers assessed the quality of the trials and extracted the data independently. All statistical analyses were performed using the standard statistical procedures in Review Manager 5.2.
We included 20 studies (N = 2917 participants) in this meta-analysis. Our results showed no significant difference in excess weight loss between Laparoscopic Roux-en-Y gastric bypass and laparoscopic sleeve gastrectomy, with pooled Standardised mean differences of -0.16 (95% confidence interval: -0.52 to 0.19; P = 0.36) based on randomized control trials and 0.07 (95% confidence interval: -0.10 to 0.24; P = 0.41) based on non-randomised interventional studies. Further, the pooled results showed no significant differences in midterm and long-term weight loss outcomes between the comparative groups. Similarly, no significant difference was found in type 2 diabetes mellitus resolution. The pooled results indicated that patients receiving laparoscopic sleeve gastrectomy experienced fewer postoperative complication and reoperation rates, with pooled risk ratios of 1.66 (95% confidence interval: 1.33 to 2.07; P < 0.00001) and 1.73 (95% confidence interval: 1.14 to 2.62; P = 0.01), respectively. Laparoscopic Roux-en-Y gastric bypass was superior to laparoscopic sleeve gastrectomy in managing dyslipidemia, hypertension and gastroesophageal reflux disease.
The present meta-analysis indicated that both Laparoscopic Roux-en-Y gastric bypass and laparoscopic sleeve gastrectomy had the same effectiveness in resulting in excess weight loss and type 2 diabetes mellitus resolution. However, patients who received laparoscopic sleeve gastrectomy experienced fewer postoperative complication and reoperation rates than those who received Laparoscopic Roux-en-Y gastric bypass. Laparoscopic Roux-en-Y gastric bypass was superior in the management of dyslipidemia, hypertension and gastroesophageal reflux disease.

Heterogeneity of weight loss after gastric bypass, sleeve gastrectomy, and adjustable gastric banding.
Laparoscopic Roux-en-Y gastric bypass, laparoscopic sleeve gastrectomy, and laparoscopic adjustable gastric banding all lead to substantial weight loss in obese patients. Long-term weight loss can be highly variable beyond 1-year postsurgery. This study examines and compares the frequency distribution of weight loss and lack of treatment effect rates after laparoscopic Roux-en-Y gastric bypass, laparoscopic sleeve gastrectomy, and laparoscopic adjustable gastric banding.
A total of 1,331 consecutive patients at a single academic institution were reviewed from a prospectively collected database. Preoperative data collected included demographics, body mass index, and percent excess weight loss. Postoperative BMI and %EWL were collected at 12, 24, and 36 months. Percent excess weight loss was analyzed by the percentiles of excess weight lost, and the distribution of percent excess weight loss was evaluated in 10% increments. Lack of a successful treatment effect was defined as <25% excess weight loss.
Of the 1,331 patients, 72.4% (963) underwent laparoscopic Roux-en-Y gastric bypass, 18.3% (243) laparoscopic sleeve gastrectomy, and 9.4%(125) laparoscopic adjustable gastric banding. Mean percent excess weight loss was greatest for laparoscopic Roux-en-Y gastric bypass, followed by laparoscopic sleeve gastrectomy, and then by laparoscopic adjustable gastric banding at every time point: at 2 years mean percent excess weight loss was 77.9± 24.4 for laparoscopic Roux-en-Y gastric bypass, 50.8 ± 25.8 for laparoscopic sleeve gastrectomy, and 40.8± 25.9 for laparoscopic adjustable gastric banding (P < .0001). The rates of a successful treatment effect s for laparoscopic Roux-en-Y gastric bypass, laparoscopic sleeve gastrectomy, and laparoscopic adjustable gastric banding were 0.9%, 5.2%, and 24.3% at 1 year; 0.3%, 11.1%, and 26.0% at 2 years; and 1.0%, 25.3%, and 30.2% at 3 years. At 1 year, the odds ratio of lack of a successful treatment effect of laparoscopic sleeve gastrectomy versus laparoscopic Roux-en-Y gastric bypass was 6.305 (2.125-19.08; P = .0004), the odds ratio for laparoscopic adjustable gastric banding versus laparoscopic Roux-en-Y gastric bypass was 36.552 (15.64-95.71; P < .0001), and the odds ratio for laparoscopic adjustable gastric banding versus laparoscopic sleeve gastrectomy was 5.791 (2.519-14.599; P < .0001). At 2 years, the odds ratio for laparoscopic sleeve gastrectomy versus laparoscopic Roux-en-Y gastric bypass increased to 70.7 (9.4-531.7; P < .0001), the odds ratio for laparoscopic adjustable gastric banding versus laparoscopic Roux-en-Y gastric bypass increased to 128.1 (16.8-974.3; P < .0001), and the odds ratio for laparoscopic adjustable gastric banding versus laparoscopic sleeve gastrectomy decreased to 1.8 (0.9-3.6; P = .09).
This study emphasizes the existing variability in weight loss across bariatric procedures as well as in the lack of a treatment effect for each procedure. Although laparoscopic adjustable gastric banding has the greatest rate of a lack of a successful treatment effect, the rate remained stable over 3 years postoperatively. Laparoscopic sleeve gastrectomy showed a doubling in the rate of a lack of a successful treatment effect every year reaching 25% at year 3. The rates for lack of a successful treatment effect for laparoscopic Roux-en-Y gastric bypass remained stable at about 1% for the first 3 years postoperatively.
