ABSTRACT: Background
Bariatric surgical operation is taken into consideration to be the handiest remedy for extreme obesity. Durability is the main requirement for the broad usage of bariatric surgery. According to several factors, the present work tries to match the SG and RYGB techniques.Methods
This is a retrospective work that studied 200 morbid obese patients randomized and categorized into two groups according to the treatment method: the laparoscopic sleeve gastrectomy (LSG) and LRYGB groups, within the period from 2014 to 2019 and matched weight dissipation, complications, quality of life, and adverse events.Results
BMI had a mean value of 39.66 ± 3.770 kg/m2 in the RYGB group versus 39.38 ± 3.648 kg/m2. No significant differences were found according to comorbidity, height, and weight. There was no significant difference between the study groups according to complications and morbidity-no recorded unexpected histopathology results in the excised LSG specimens.Conclusion
There was no significant change in weight dissipation, fluctuations in comorbidities, increase in Quality of Life (QoL), and complications for pathological obesity patients according to the treatment methods of laparoscopic SG (sleeve gastrectomy) and RYGB at 2-years postoperative follow-up.

Project description:Importance:Sleeve gastrectomy is increasingly used in the treatment of morbid obesity, but its long-term outcome vs the standard Roux-en-Y gastric bypass procedure is unknown. Objective:To determine whether there are differences between sleeve gastrectomy and Roux-en-Y gastric bypass in terms of weight loss, changes in comorbidities, increase in quality of life, and adverse events. Design, Setting, and Participants:The Swiss Multicenter Bypass or Sleeve Study (SM-BOSS), a 2-group randomized trial, was conducted from January 2007 until November 2011 (last follow-up in March 2017). Of 3971 morbidly obese patients evaluated for bariatric surgery at 4 Swiss bariatric centers, 217 patients were enrolled and randomly assigned to sleeve gastrectomy or Roux-en-Y gastric bypass with a 5-year follow-up period. Interventions:Patients were randomly assigned to undergo laparoscopic sleeve gastrectomy (n = 107) or laparoscopic Roux-en-Y gastric bypass (n = 110). Main Outcomes and Measures:The primary end point was weight loss, expressed as percentage excess body mass index (BMI) loss. Exploratory end points were changes in comorbidities and adverse events. Results:Among the 217 patients (mean age, 45.5 years; 72% women; mean BMI, 43.9) 205 (94.5%) completed the trial. Excess BMI loss was not significantly different at 5 years: for sleeve gastrectomy, 61.1%, vs Roux-en-Y gastric bypass, 68.3% (absolute difference, -7.18%; 95% CI, -14.30% to -0.06%; P = .22 after adjustment for multiple comparisons). Gastric reflux remission was observed more frequently after Roux-en-Y gastric bypass (60.4%) than after sleeve gastrectomy (25.0%). Gastric reflux worsened (more symptoms or increase in therapy) more often after sleeve gastrectomy (31.8%) than after Roux-en-Y gastric bypass (6.3%). The number of patients with reoperations or interventions was 16/101 (15.8%) after sleeve gastrectomy and 23/104 (22.1%) after Roux-en-Y gastric bypass. Conclusions and Relevance:Among patients with morbid obesity, there was no significant difference in excess BMI loss between laparoscopic sleeve gastrectomy and laparoscopic Roux-en-Y gastric bypass at 5 years of follow-up after surgery.

Project description:Importance:Laparoscopic sleeve gastrectomy for treatment of morbid obesity has increased substantially despite the lack of long-term results compared with laparoscopic Roux-en-Y gastric bypass. Objective:To determine whether laparoscopic sleeve gastrectomy and laparoscopic Roux-en-Y gastric bypass are equivalent for weight loss at 5 years in patients with morbid obesity. Design, Setting, and Participants:The Sleeve vs Bypass (SLEEVEPASS) multicenter, multisurgeon, open-label, randomized clinical equivalence trial was conducted from March 2008 until June 2010 in Finland. The trial enrolled 240 morbidly obese patients aged 18 to 60 years, who were randomly assigned to sleeve gastrectomy or gastric bypass with a 5-year follow-up period (last follow-up, October 14, 2015). Interventions:Laparoscopic sleeve gastrectomy (n = 121) or laparoscopic Roux-en-Y gastric bypass (n = 119). Main Outcomes and Measures:The primary end point was weight loss evaluated by percentage excess weight loss. Prespecified equivalence margins for the clinical significance of weight loss differences between gastric bypass and sleeve gastrectomy were -9% to +9% excess weight loss. Secondary end points included resolution of comorbidities, improvement of quality of life (QOL), all adverse events (overall morbidity), and mortality. Results:Among 240 patients randomized (mean age, 48 [SD, 9] years; mean baseline body mass index, 45.9, [SD, 6.0]; 69.6% women), 80.4% completed the 5-year follow-up. At baseline, 42.1% had type 2 diabetes, 34.6% dyslipidemia, and 70.8% hypertension. The estimated mean percentage excess weight loss at 5 years was 49% (95% CI, 45%-52%) after sleeve gastrectomy and 57% (95% CI, 53%-61%) after gastric bypass (difference, 8.2 percentage units [95% CI, 3.2%-13.2%], higher in the gastric bypass group) and did not meet criteria for equivalence. Complete or partial remission of type 2 diabetes was seen in 37% (n = 15/41) after sleeve gastrectomy and in 45% (n = 18/40) after gastric bypass (P > .99). Medication for dyslipidemia was discontinued in 47% (n = 14/30) after sleeve gastrectomy and 60% (n = 24/40) after gastric bypass (P = .15) and for hypertension in 29% (n = 20/68) and 51% (n = 37/73) (P = .02), respectively. There was no statistically significant difference in QOL between groups (P = .85) and no treatment-related mortality. At 5 years the overall morbidity rate was 19% (n = 23) for sleeve gastrectomy and 26% (n = 31) for gastric bypass (P = .19). Conclusions and Relevance:Among patients with morbid obesity, use of laparoscopic sleeve gastrectomy compared with use of laparoscopic Roux-en-Y gastric bypass did not meet criteria for equivalence in terms of percentage excess weight loss at 5 years. Although gastric bypass compared with sleeve gastrectomy was associated with greater percentage excess weight loss at 5 years, the difference was not statistically significant, based on the prespecified equivalence margins.

Project description:ImportanceLaparoscopic sleeve gastrectomy (LSG) is currently the predominant bariatric procedure, although long-term weight loss and quality-of-life (QoL) outcomes compared with laparoscopic Roux-en-Y gastric bypass (LRYGB) are lacking.ObjectiveTo determine weight loss equivalence of LSG and LRYGB at 7 years in patients with morbid obesity, with special reference to long-term QoL.Design, setting, and participantsThe SLEEVE vs byPASS (SLEEVEPASS) multicenter, multisurgeon, open-label, randomized clinical equivalence trial was conducted between March 10, 2008, and June 2, 2010, in Finland. The trial enrolled 240 patients with morbid obesity aged 18 to 60 years who were randomized to undergo either LSG or LRYGB with a 7-year follow-up (last follow-up, September 26, 2017). Analysis was conducted on an intention-to-treat basis. Statistical analysis was performed from June 4, 2018, to November 8, 2019.InterventionsLaparoscopic sleeve gastrectomy (n = 121) or LRYGB (n = 119).Main outcomes and measuresThe primary end point was percentage excess weight loss (%EWL) at 5 years. Secondary predefined follow-up time points were 7, 10, 15, and 20 years, with included 7-year secondary end points of QoL and morbidity. Disease-specific QoL (DSQoL; Moorehead-Ardelt Quality of Life questionnaire [range of scores, -3 to 3 points, where a higher score indicates better QoL]) and general health-related QoL (HRQoL; 15D questionnaire [0-1 scale for all 15 dimensions, with 1 indicating full health and 0 indicating death]) were measured preoperatively and at 1, 3, 5, and 7 years postoperatively concurrently with weight loss.ResultsOf 240 patients (167 women [69.6%]; mean [SD] age, 48.4 [9.4] years; mean [SD] baseline body mass index, 45.9 [6.0]), 182 (75.8%) completed the 7-year follow-up. The mean %EWL was 47% (95% CI, 43%-50%) after LSG and 55% (95% CI, 52%-59%) after LRYGB (difference, 8.7 percentage units [95% CI, 3.5-13.9 percentage units]). The mean (SD) DSQoL total score at 7 years was 0.50 (1.14) after LSG and 0.49 (1.06) after LRYGB (P = .63), and the median HRQoL total score was 0.88 (interquartile range [IQR], 0.78-0.95) after LSG and 0.87 (IQR, 0.78-0.95) after LRYGB (P = .37). Greater weight loss was associated with better DSQoL (r = 0.26; P < .001). At 7 years, mean (SD) DSQoL scores improved significantly compared with baseline (LSG, 0.50 [1.14] vs 0.10 [0.94]; and LRYGB, 0.49 [1.06] vs 0.12 [1.12]; P < .001), unlike median HRQoL scores (LSG, 0.88 [IQR, 0.78-0.95] vs 0.87 [IQR, 0.78-0.90]; and LRYGB, 0.87 [IQR, 0.78-0.92] vs 0.85 [IQR, 0.77-0.91]; P = .07). The overall morbidity rate was 24.0% (29 of 121) for LSG and 28.6% (34 of 119) for LRYGB (P = .42).Conclusions and relevanceThis study found that LSG and LRYGB were not equivalent in %EWL at 7 years. Laparoscopic Roux-en-Y gastric bypass resulted in greater weight loss than LSG, but the difference was not clinically relevant based on the prespecified equivalence margins. There was no difference in long-term QoL between the procedures. Bariatric surgery was associated with significant long-term DSQoL improvement, and greater weight loss was associated with better DSQoL.Trial registrationClinicalTrials.gov Identifier: NCT00793143.

Project description:The purpose of the study was to compare weight loss, metabolic parameters, and postoperative complications in patients undergoing Roux-en-Y gastric bypass (GB) and sleeve gastrectomy (SG).We retrospectively studied 30-day postoperative complications as well as change in weight, blood pressure, cholesterol, hemoglobin, hemoglobin A1C, and creatinine from baseline to 2, 6, 12, and 24 months postoperatively in 383 patients undergoing GB and 336 patients undergoing SG at the University of Michigan from January 2008 to November 2013. For a study population which typically has high attrition rates, there were excellent follow-up rates (706/719 at 2 months, 566/719 at 6 months, 519/719 at 12 months, and 382/719 at 24 months).Baseline characteristics were similar in both groups except for higher weight and BMI in the SG group. The GB group experienced greater total body weight loss at 6, 12, and 24 months (41.9 vs. 34.6 kg at 24 months, p < 0.0001). Excess weight loss was 69.7 and 51.7 % following GB and SG respectively at 24 months (p < 0.0001). BP improved significantly in both groups. Surgical complication rates were greater after GB (10.1 vs. 3.5 %, p = 0.0007) with no significant difference in life-threatening or potentially life-threatening complications.Weight loss was greater following GB compared to SG at 2 years. The risk for surgical complications was greater following GB. Surgical intervention should be tailored to surgical risk, comorbidities, and desired weight loss.

Project description:BACKGROUND:Laparoscopic Roux-en-Y gastric bypass (LRYGB) is one of the most widely used bariatric procedures, and laparoscopic sleeve gastrectomy (LSG) as a single-stage procedure for treating morbid obesity is becoming more popular. We compared both techniques to evaluate their efficacy in treating morbid obesity or type 2 diabetes mellitus (T2DM). METHODS:We searched the Cochrane Controlled Trials Register databases, Medline, Embase, ISI databases and the Chinese Biomedical Literature Database to identify randomized controlled trials (RCTs) of LRYGB and LSG for morbid obesity or T2DM published in any language. Statistical analyses were carried out using RevMan software. RESULTS:Five worldwide RCTs with 196 patients in the LRYGB group and 200 in the LSG group were included in our analysis. Compared with patients who had LSG, those who had LRYGB had a higher remission rate of T2MD, lost more weight and had lower low-density lipoprotein, triglycerides, homeostasis model assessment index and insulin levels. There was no difference in the reoperation rate between the groups. However, patients treated with LRYGB had a higher incidence of complication than those treated with LSG. CONCLUSION:Our meta-analysis demonstrates that LRYGB is more effective than LSG for the surgical treatment of T2DM and control of metabolic syndrome. However, LSG is safer and has a reduced rate of complications. Further high-quality RCTs with long follow-up periods are needed to provide more reliable evidence.

Project description:BackgroundA meta-analysis and six randomized controlled trials show higher 30-day complication rates with laparoscopic Roux-en-Y gastric bypass (LRYGB) than with laparoscopic sleeve gastrectomy (LSG).AimTo identify any difference in 30-day outcomes of patients treated with LRYGB or LSG when a standardized technique and identical post-operative protocol was followed with all procedures being conducted either by or under the supervision of a single consultant surgeon who had significant experience in bariatric surgery prior to commencing independent practice.MethodsA prospectively collected database of all patients under primary LRYGB or LSG, between March 2010 and February 2017, was analyzed. Data on demographics, length-of-stay (LOS), conversion to open, 30-day complications and mortality were reviewed.ResultsOver a seven-year period, 485 patients (LRYGB-279 and LSG-206) were included. There were no significant demographic differences and no difference in the pre-operative risk scoring [American Society of Anesthesiologists (ASA) and obesity surgery mortality risk score (OSMRS)] between the groups. There was no significant difference between the groups in terms of LOS (p = 0.275), complications (p = 0.920), re-admissions (p = 0.593) or re-operations (p = 0.366) within 30-days. There were no conversions to open or in-patient mortality in either group.ConclusionsUnlike previous studies, we found no difference in early complication rates between LRYGB and LSG in a comparable cohort when performed by a surgeon with sufficient experience in bariatric surgery.

Project description:Importance:Bariatric surgery is an effective and safe approach for weight loss and short-term improvement in metabolic disorders such as diabetes. However, studies have been limited in most settings by lack of a nonsurgical group, losses to follow-up, missing data, and small sample sizes in clinical trials and observational studies. Objective:To assess the association of 3 common types of bariatric surgery compared with nonsurgical treatment with mortality and other clinical outcomes among obese patients. Design, Setting, and Participants:Retrospective cohort study in a large Israeli integrated health fund covering 54% of Israeli citizens with less than 1% turnover of members annually. Obese adult patients who underwent bariatric surgery between January 1, 2005, and December 31, 2014, were selected and compared with obese nonsurgical patients matched on age, sex, body mass index (BMI), and diabetes, with a final follow-up date of December 31, 2015. A total of 33 540 patients were included in this study. Exposures:Bariatric surgery (laparoscopic banding, Roux-en-Y gastric bypass, or laparoscopic sleeve gastrectomy) or usual care obesity management only (provided by a primary care physician and which may include dietary counseling and behavior modification). Main Outcomes and Measures:The primary outcome, all-cause mortality, matched and adjusted for BMI prior to surgery, age, sex, socioeconomic status, diabetes, hyperlipidemia, hypertension, cardiovascular disease, and smoking. Results:The study population included 8385 patients who underwent bariatric surgery (median age, 46 [IQR, 37-54] years; 5490 [65.5%] women; baseline median BMI, 40.6 [IQR, 38.5-43.7]; laparoscopic banding [n = 3635], gastric bypass [n = 1388], laparoscopic sleeve gastrectomy [n = 3362], and 25 155 nonsurgical matched patients (median age, 46 [IQR, 37-54] years; 16 470 [65.5%] women; baseline median BMI, 40.5 [IQR, 37.0-43.5]). The availability of follow-up data was 100% for all-cause mortality. There were 105 deaths (1.3%) among surgical patients during a median follow-up of 4.3 (IQR, 2.8-6.6) years (including 61 [1.7%] who underwent laparoscopic banding, 18 [1.3%] gastric bypass, and 26 [0.8%] sleeve gastrectomy), and 583 deaths (2.3%) among nonsurgical patients during a median follow-up of 4.0 (IQR, 2.6-6.2) years. The absolute difference was 2.51 (95% CI, 1.86-3.15) fewer deaths/1000 person-years in the surgical vs nonsurgical group. Adjusted hazard ratios (HRs) for mortality among nonsurgical vs surgical patients were 2.02 (95% CI, 1.63-2.52) for the entire study population; by surgical type, HRs were 2.01 (95% CI, 1.50-2.69) for laparoscopic banding, 2.65 (95% CI, 1.55-4.52) for gastric bypass, and 1.60 (95% CI, 1.02-2.51) for laparoscopic sleeve gastrectomy. Conclusions and Relevance:Among obese patients in a large integrated health fund in Israel, bariatric surgery using laparoscopic banding, gastric bypass, or laparoscopic sleeve gastrectomy, compared with usual care nonsurgical obesity management, was associated with lower all-cause mortality over a median follow-up of approximately 4.5 years. The evidence of this association adds to the limited literature describing beneficial outcomes of these 3 types of bariatric surgery compared with usual care obesity management alone.

Project description:ImportanceData on the long-term health care expenditures associated with bariatric surgery consisting of Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy are lacking.ObjectiveTo compare 4-year health care expenditures after RYGB vs sleeve gastrectomy, identify factors independently associated with 4-year health care expenditures, and compare the procedures in terms of subsequent hospitalizations, bariatric procedures, and all-cause mortality.Design, setting, and participantsIn this propensity score-matched cohort study, all residents of Ontario, Canada, who underwent publicly funded surgery with RYGB (n = 6301) or sleeve gastrectomy (n = 926) from March 1, 2010, to March 31, 2015, and consented to participate in the Ontario Bariatric Registry were eligible for the study. Follow-up was completed on March 31, 2019, and data were analyzed from May 5, 2020, to May 20, 2021.InterventionsRYGB and sleeve gastrectomy.Main outcomes and measuresPublicly funded health care expenditures, subsequent hospitalizations, bariatric procedures, and mortality during the 4 years after RYGB or sleeve gastrectomy.ResultsThe 1:1 matched study cohorts consisted of 1624 patients (812 per cohort) with a mean (SD) age of 48.0 (10.6) years, and 1242 women (76.5%). The mean body mass index (calculated as weight in kilograms divided by height in square meters) was 51.9 (8.3) for the RYGB cohort and 51.9 (8.9) for the sleeve gastrectomy cohort. The 4-year cumulative costs were not statistically significantly different between RYGB and sleeve gastrectomy (mean [SD], $33 682 [$31 169] vs $33 948 [$32 633], respectively; P = .86). Having a history of coronary artery disease was associated with a 35% increase in overall health care expenditures; chronic kidney disease, a 54% increase; and mental health admissions, a 67% increase. There were no statistically significant differences in all-cause mortality between RYGB and sleeve gastrectomy (1.5% vs 2.2%, respectively; P = .26) or the total number of hospitalizations (754 vs 669, respectively; P = .11) during the 4-year follow-up period. However, nonelective hospitalizations occurred more frequently with RYGB vs sleeve gastrectomy (472 vs 339, respectively; P = .002). Roux-en-Y gastric bypass was associated with relatively fewer subsequent bariatric procedures during the 4-year follow-up period (9 vs 40, respectively; P < .001).Conclusions and relevanceIn this Canadian population-based study, key results indicated that 4-year health care expenditures, all-cause mortality, and number of hospital admissions associated with RYGB did not significantly differ from those for sleeve gastrectomy. The rate of subsequent bariatric surgery was lower with RYGB. This study identified important patient-level drivers of health care expenditures that need to be further investigated.

Project description:BACKGROUND:Bariatric surgery is known to decrease weight and the prevalence of comorbidities, but there is little evidence on the differential effect of Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) on the remission of the aggregate outcome, metabolic syndrome, 4 years after surgery. The purpose of this study was to determine the effectiveness of RYGB and SG on metabolic syndrome in veterans. METHODS:We retrospectively reviewed consecutive patients who underwent SG and RYGB at the Dallas Veterans Affairs Medical Center from 2003 to 2012. We determined the effect of both the operations on the remission of metabolic syndrome, its individual components, and medium-term morbidity and mortality. A sensitivity analysis was performed using propensity matching. RESULTS:A total of 266 patients were identified (159 RYGB and 107 SG) with 96% follow-up after 4 years. The mean age of the cohort was 51.4 years; the majority of patients were male (59%) and Caucasian (69%). RYGB patients had a greater mean body mass index and were more likely to have hypertension or hypertriglyceridemia. RYGB was associated with a similar metabolic syndrome remission to SG (37.6% vs 26.8%; P=0.09). The percentage of weight loss was 26.5% after RYGB and 10.8% after SG at 4 years post operation (P<0.01). Predictors of metabolic syndrome persistence were male gender, type 2 diabetes, and low high-density lipoprotein. While both the operations were associated with similar mortality (RYGB 4.4%, SG 2.8%; P=0.74), RYGB was associated with a greater rate of morbidity. CONCLUSION:RYGB and SG seem to be associated with similar remission rates of metabolic syndrome at 4 years. RYGB yields greater weight loss with greater medium-term complications.

Project description:BackgroundLaparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG) are two representative bariatric surgeries. This study aimed to compare the effects of the LSG and LRYGB based on high-quality analysis and massive amount of data.MethodsFor this study databases of PubMed, Web of Science, EBSCO, Medline, and Cochrane Library were searched for articles published until January 2019 comparing the outcomes of LSG and LRYGB.ResultsThis study included 28 articles. Overall, 9038 patients (4597, LSG group; 4441, LRYGB group) were included. The remission rate of type 2 diabetes mellitus (T2DM) in the LRYGB group was superior to that in the LSG group at the 3-years follow-up. Five-year follow-up results showed that LRYGB had an advantage over LSG for the percentage of excess weight loss and remission of T2DM, hypertension, dyslipidemia, and abnormally low-density lipoprotein.ConclusionsIn terms of the long-term effects of bariatric surgery, the effect of LRYGB was better than of LSG.
