Outcomes Of Laparoscopic Gastric Bypass Research Articles

Is There an Upper Age Limit for Bariatric Surgery? Laparoscopic Gastric Bypass Outcomes in Septuagenarians.

Upper age limits for bariatric surgery are questioned on the merits of increased complication rates in the elderly and questionable efficacy. This study evaluates outcomes of bariatric surgery in patients ≥ 70years of age. Retrospective review was performed of patients ≥ 70years of age who underwent laparoscopic Roux-en-Y gastric bypass (RYGB) between 2001 and 2018. Primary endpoints were 30-day readmission, Clavien-Dindo grade III-V (CD III-IV) complications, and mortality. Secondary data included were weight loss, long-term outcomes, comorbidity resolution, hemoglobin A1C, and lipid panels. A total of 23 patients with an average age of 72years (range 70-80years) and mean BMI of 43.3 (range 37.3-56.0) were reviewed. Average length-of-stay was 2.4days (range 1-6days), with the only acute complication being aspiration pneumonia in one patient. Median follow-up was 69.3weeks (range 9-875weeks). One-year follow-up rate was 96%, during which no deaths or CD III-IV complications occurred. Subsequently, one patient experienced failure-to-thrive requiring temporary enteral nutrition. Average 1year percent total weight loss (%TWL) was 29%, and this was maintained on subsequent follow-ups. Average 1year percent excess weight loss (%EWL) was 60%, maintained long-term at 61%. Significant serum biochemical improvements included hemoglobin A1C (6.9 ± 1.4% to 5.6 ± 1.3%, p = 0.001), triglycerides (155 ± 49mg/dL to 102 ± 41mg/dL, p = 0.0003), and high-density lipoprotein cholesterol (48 ± 14mg/dL to 58 ± 22mg/dL, p = 0.004). Laparoscopic RYGB is a safe and effective treatment for obesity and obesity-related comorbidities in septuagenarians.

Safety of concomitant cholecystectomy with laparoscopic sleeve gastrectomy and gastric bypass: a MBSAQIP analysis

BackgroundGallstone disease occurs more commonly in the obese population and is often diagnosed during the preoperative evaluation for bariatric surgery. ObjectivesThis study analyzed outcomes of laparoscopic gastric bypass (LGB) and laparoscopic sleeve gastrectomy (SG), with and without cholecystectomy (LC), using data from the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program. SettingPatients reported to Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program participating centers in the United States and Canada in 2015. MethodsAll cases of LGB and SG, with and without LC, were analyzed. A 1:1 propensity-matched cohort was created for both SG and LGB, with and without concomitant LC. Multivariate logistic regression stratified by procedure was used to identify predictors of major complications after SG and LGB, using concomitant LC as a predictor. We also constructed a model for surgical site infections (SSIs) for SG group. ResultsOf 98,292 sleeve operations, 2046 (2%) had concomitant LC. Of 44,427 bypass operations, 1426 (3%) had concomitant LC. For the sleeve group, concomitant LC increased operative time by an average of 27 minutes but did not affect length of stay, mortality, or major complications. Concomitant LC was associated with increased SSI (1% versus .4%) and need for reoperation (1.6% versus .7%) in univariate models. After adjusting for other predictors, concomitant LC was associated with increased risk for SSI (odds ratio 2.5, confidence interval 1.0–5.9, P = .04). For the bypass group, concomitant LC increased operative time by an average of 28 minutes to the operation, and postoperative length of stay averaged ∼5 hours longer (2.4 versus 2.2 d, P = .03). Thirty-day complications were similar between the groups. On multivariate analysis, concomitant LC was not a significant risk factor for major complications. Only operative time was an independent factor for major complications. ConclusionsConcomitant LC with laparoscopic sleeve gastrectomy or gastric bypass did not affect mortality or risk of major complication. For sleeve patients, concomitant LC was associated with a .6% increased risk (.4% to 1.0%) of SSI. Concomitant LC with laparoscopic sleeve gastrectomy or gastric bypass is safe when indicated for gallstone disease.

Outcome of laparoscopic gastric bypass in obese and diabetic patients: when surgery fails

The beneficial effects of bariatric surgery on diabetes and obesity have been widely demonstrated in the literature. The aim of our study was to evaluate the rate of failure of laparoscopic gastric bypass both in terms of weight loss and metabolic remission after one follow-up year. A longitudinal, multicenter prospective study was carried out on 771 patients affected by pathological obesity. The following parameters were recorded for each patient before surgery: anthropometric, metabolic, social, smoking habits and previous failure of other bariatric procedures. After 1 follow-up year, final weight, final Body Mass Index (BMI), final percentage of lost excess body weight and percentage of lost BMI were evaluated. Statistical analysis showed a correlation between BMI>50 kg/m2, presence of metabolic syndrome, presence of diabetes, gastric pouch volume greater than 60 mL and failure of weight loss outcome. Statistical analysis of metabolic failure has recognized a high preoperative glycated hemoglobin percentage (HbA1c%) value as a statistically significant negative predictive factor. Bariatric Surgery is the most effective treatment for weight loss and metabolic improvement. However, in our study, surgery did not achieve the expected outcome in patients with specific metabolic, anthropometric and surgical characteristics (BMI>50 kg/m2, presence of metabolic syndrome, presence of T2DM with high preoperative HbA1c% level and gastric pouch volume greater than 60 mL).

Outcome of Laparoscopic Gastric Bypass (LRYGB) with a Program for Enhanced Recovery After Surgery (ERAS)

Enhanced recovery after surgery (ERAS) programs are well established for patients undergoing colorectal surgery. Relatively little is known about ERAS following bariatric surgery in general or following laparoscopic Roux-en-Y gastric bypass (LRYGB) in particular. This is a prospective, observational study of 388 consecutive patients that underwent LRYGB with ERAS in a general hospital. The ERAS protocol included standardizations of pre-, intra-, and postoperative modalities in order to reduce the stress response of the patients. Primary outcome measures were length of stay (LOS), postoperative morbidity, readmissions, and reoperations. Mean (SD) baseline body mass index (BMI) and age was 46.4 (6.7) kg/m(2) and 45.1 (11.2) years, respectively. Fifty-four percent of the patients were on medication for hypertension (HT) and 38 % for type 2 diabetes mellitus (DM2). Mean (SD) and median (range) surgical time was 73.8 (16.9) and 65 (40-143) min, respectively. Mean LOS was 1.3 days (1.1), median 1 day (1-14). Of all patients, 322 (83 %) were discharged on the first postoperative day (POD). Overall morbidity was 9.8 %. Three patients (0.8 %) had life-threatening complications. The readmission rate was 4.9 %, and 3.4 % of the patients had to be reoperated. With a follow-up rate of 83 % at 1 year, total weight loss (TWL) was 31 % and excess BMI loss (EBMIL) 70 %. Total remission of DM2 and HT was achieved in 70 and 42 % of the patients, respectively. Enhanced recovery following LRYGB with ERAS programs is possible and safe even in a low volume, general hospital. Early discharge does not increase postoperative morbidity or readmissions.

Effect of binge eating disorder on the outcomes of laparoscopic gastric bypass in the treatment of morbid obesity.

Previous studies about the effect of binge eating disorder (BED) on the outcomes of laparoscopic gastric bypass (LGBP) are controversial. These studies have not compared patients with and without BED according to the Bariatric Analysis and Reporting Outcome System (BAROS), which takes into account weight loss, correction of comorbidities, improvement in quality of life and complications. To assess whether BED predicts worse outcomes after LGBP, according to BAROS parameters. We carried out a cohort study which included 45 morbidly obese patients operated with LGBP. Patients with preoperative BED were identified by Questionnaire on Eating and Weight Patterns-Revised and results were evaluated by BAROS system. Prevalence of BED was 21.4%. Median postoperative follow-up was 12 months. BED patients experienced after LGBP lower rates of resolution of hypertension (42.9% vs. 92.9%; p = 0.025) and were complicated by stenosis of the gastrojejunal anastomosis more frequently (70% vs. 17.1%; p = 0.003) than patients without binge eating. No differences in BAROS score, percentage of excess weight loss and quality of life were found. BED patients experienced after LGBP lower rates of resolution of hypertension and higher rates of anastomotic stenosis. BAROS score, weight loss and quality of life are comparable to that of patients without BED.

Diagnostic and psychopathologic evaluation of binge eating disorder in gastric bypass patients

The presence of binge eating disorder (BED) can influence the outcomes of laparoscopic gastric bypass (BPGL) in the treatment of morbid obesity. In English population, BED is assessed usually through the Eating Disorder Examination-Questionnaire (EDE-Q) and Questionnaire on Eating and Weight Patterns-Revised (QEWP-R). To study validity and concordance of EDEQ and QEWP-R for diagnosis and psychopathologic assessment of BED in Spanish gastric bypass patients. In a cross sectional study 27 recent gastric bypass patients completed Spanish version of EDE-Q and QEWP-R. Then patients were classified in BED or no BED. We evaluated possible differences between these groups in the items with psychometric relevance and we measure concordance between the questionnaires. The QEWP-R and EDE-Q identified respectively 25,9% and 18,5% patients with BED. These achieved higher scores in the items related to importance of weight or shape in self-assessment, interference in concentration because of thinking about food, shape or weight, and frequency of guilty feeling after eating. Diagnostic concordance was poor between questionnaires, but we found a strong relation between items with psychometric relevance. BED is frequent in gastric bypass patients and constitute a distinct subgroup of patients with more severe psychopathology. Spanish version of QEWP-R and EDE-Q are suitable questionnaires for assessment of BED.

Preoperative Weight Loss with Intragastric Balloon Decreases the Risk of Significant Adverse Outcomes of Laparoscopic Gastric Bypass in Super-Super Obese Patients

Extreme obesity increases morbi-mortality in bariatric surgery. We previously showed that significant weight loss can be obtained within 3 months in super-super obese patients (BMI > 60 kg/m(2)) with an intragastric balloon (IGB). Here, we explored the potential benefit of preoperative IGB on the outcome of laparoscopic gastric bypass (LGBP) in super-super obese patients. In this case-control study, we compared the records of 60 consecutive super-super obese patients (66.5 ± 3.4 kg/m(2)) submitted to a LGBP between 2004 and 2009, with preoperative IGB (n = 23, cases) or without (n = 37, controls). We analyzed the clinical outcome of surgery and a composite end point of significant adverse events defined as the presence of at least one of the following conditions: conversion to laparotomy, intensive care unit stay for more than 2 days, and overall hospital stay superior to 2 weeks. All baseline clinical and biological characteristics were homogenous between both groups. IGB was maintained during 155 ± 62 days and induced a loss of 5.5 ± 1.3 kg/m(2) (11.2 ± 3.2% of excess body mass index) at the time of LGBP, associated with a decrease in systolic blood pressure and gamma-glutamyl transpeptidase level (p < 0.05 vs. baseline). Operative time was lower in the IGB group (146 ± 47 vs. 201 ± 81 min in controls; p < 0.01). Significant adverse events occurred less frequently after LGBP in the IGB group (2 vs. 13 in controls; p < 0.05). All patients were alive at 1 year and overall weight loss was similar in both groups (52.4 ± 17.3 vs. 50.3 ± 12.7 percent of excess BMI loss in controls; NS). IGB prior to LGBP in super-super obese patients significantly reduced excess BMI. It was associated with a shorter operative time and a lower overall risk of significant adverse outcomes.

The impact of previous fundoplication on laparoscopic gastric bypass outcomes: a case-control evaluation

Gastroesophageal reflux disease (GERD) is a common comorbid condition in morbidly obese gastric bypass candidates. Unfortunately, some patients who ultimately present for bariatric surgery have previously undergone Nissen fundoplication for GERD. Many surgeons consider previous fundoplication to be a relative contraindication to subsequent laparoscopic Roux-en-Y gastric bypass (LRYGB) due to increased technical complexity and risk. We sought to compare the perioperative and long-term outcomes of a cohort of patients who had first undergone fundoplication and ultimately chose to later pursue LRYGB for morbid obesity (revision) to matched control patients. Data were obtained from our prospectively maintained bariatric surgery database. Patients who underwent laparoscopic takedown of a previous fundoplication and conversion to LRYGB were compared to control patients who underwent primary LRYGB. For every revision patient, two control subjects were randomly selected from the database after matching for preoperative body mass index and year of surgery. From July 2002 to April 2011, 14 patients underwent laparoscopic takedown of a previous Nissen fundoplication and then underwent LRYGB. During the same interval, 673 patients underwent LRYGB as a primary procedure for obesity from which 28 were selected as controls. There were no conversions to open laparotomy in any patient. Subjects were similar demographically. Operating time and duration of hospital stay were significantly longer in revision patients. Complications were more frequent in revisions (36% revisions vs. 7% controls, P=0.03). Excess weight loss 1-year after surgery was excellent in both groups and did not differ (69% revision vs. 69.6% controls, P=0.93). Although associated with longer operating times, longer duration of hospital stay, and complications, LRYGB after fundoplication is feasible and safe. Long-term weight loss outcomes are similar to those seen following primary LRYGB. Previous fundoplication is not a contraindication to LRYGB.

Preoperative determinants of outcomes of laparoscopic gastric bypass in the treatment of morbid obesity.

Laparoscopic gastric bypass (LGBP) is the predominant technique in surgical treatment of morbid obesity. To evaluate the results of LGBP and measure the validity of some hypothetical variables as predictors of these outcomes. We carried out a historical cohort study which included 50 morbidly obese patients operated with LGBP. The results were assessed by the Bariatric Analysis and Reporting Outcome System (BAROS), which measures the following parameters: the percentage of excess weight loss (EWL), changes in co-morbidities, quality of life and complications. The independent variables were age, body mass index (BMI), sex, history of depression and presence of more than one cardiovascular risk factor (CVRF). Following LGBP, 11% of the results was classified as excellent, 54% as very good, 25% as good and 9% as fair (median follow-up period: 17 months, 7-37). The best scores were found among younger patients. The EWL (mean: 55.4 ± 16.6%) was higher in patients with lower BMI and with no more than one cardiovascular risk factor. We obtained rates of resolution of CVRF of 43.7 to 68.7%, complication rates < 10% and improvement of quality of life. We believe that, following LGBP in morbidly obese patients, when EWL, improvement in comorbidities and quality of life as well as complications are jointly assessed, the best results are obtained in younger patients.

Differences in outcomes of laparoscopic gastric bypass

Background Although several risk factors affecting weight loss outcomes with bariatric procedures have been identified, the effect of age, gender, race, and illness severity on postoperative outcomes of laparoscopic gastric bypass has not been extensively examined. Methods The University HealthSystem Consortium database is an administrative and financial database that provides information on the inpatient stay. A retrospective analysis of patient outcomes was performed using 4-year discharge data from the University HealthSystem Consortium database. Results A total of 37,765 patients underwent laparoscopic gastric bypass. The women exhibited significantly reduced mortality, morbidity, intensive care unit (ICU) admissions (9.87% male versus 6.73% female; P <.001), duration of hospitalization (2.72 ± 4.03 d for men versus 2.59 ± 2.88 d for women; P <.001), and hospital costs ($17,346 ± $15,397 for men versus $14,383 ± $11,170 for women; P <.001). Blacks demonstrated significantly greater 30-day readmission rates, duration of hospitalization, and costs compared with whites. Hispanics had lower ICU admission and hospital costs compared with whites. With increasing age, an increased risk of overall morbidity, ICU admissions, duration of hospitalization, and costs was observed. Compared with the minor severity group, the major/extreme severity group had significantly greater observed mortality, overall morbidity, ICU admissions, duration of hospitalization, and hospital costs. Conclusion The present study identified gender, race, age, and illness severity as risk factors affecting postoperative outcomes after laparoscopic gastric bypass. Male gender and increasing age were overall associated with an increased risk of complications. Significant racial disparities in the outcome measures were observed with blacks having an increased risk of adverse events. Illness severity was shown to adversely affect the surgical outcomes in laparoscopic gastric bypass.

Excellent Laparoscopic Gastric Bypass Outcomes Can be Achieved at a Community-Based Training Hospital With Moderate Case Volume

Our objective was to assess laparoscopic gastric bypass outcomes in a moderate case volume setting. Laparoscopic gastric bypass remains one of the most advanced laparoscopic procedures currently performed worldwide. The following represents a single institutional series from a community hospital-based training program with a minimally invasive bariatric surgical program. Data from all patients undergoing laparoscopic gastric bypass since the inception of the program were entered into a prospective database. Measured outcomes included length of operation, length of stay, major and minor complications, and percentage excess weight loss. Results were compared with published outcomes from a review of the literature encompassing more than 3400 cases using chi and Fisher exact tests. Between September 2001 and October 2008, 700 consecutive patients underwent laparoscopic gastric bypass. The mean age was 43.1 +/- 9.5 years, and 83% were female. The mean initial weight was 135.5 +/- 22.4 kg. The initial body mass index was 47.9 +/- 6 kg/m. The mean length of stay was 2.2 +/- 0.9 days. The length of operation was 147.8 +/- 31.8 minutes. The mean percent excess weight loss at 1-year postoperative was 72.4%. There were no mortalities. Compared with the literature, we achieved a lower rate of anastomotic leak (0.3% vs. 2%, P = 0.001) and stomal stenosis (1% vs. 4.7%, P = 0.001). Excellent outcomes following laparoscopic gastric bypass can be achieved in a community hospital-based program with moderate case volume. Reimbursement decisions should take into consideration a program's actual outcomes rather than volume.

Effect of preoperative weight loss on laparoscopic gastric bypass outcomes

Background Requiring patients to lose weight before weight reduction surgery is controversial. The goal of this study was to determine whether preoperative weight loss affects laparoscopic Roux-en- Y gastric bypass surgery outcomes. Methods The medical records of all laparoscopic Roux-en- Y gastric bypass patients from September 1, 2001 to March 31, 2005 were retrospectively reviewed in our prospective database. Depending on their habitus, patients were selectively required to lose >4.54 kg (10 lb) preoperatively (WL group). Their outcomes were compared with those of the patients not required to lose weight preoperatively (no-WL group). Statistical analysis was performed with the chi-square test and Student's t test for demographic data. Student's t test was used to assess the outcome data. P <.05 was considered significant. Results Of the 353 patients, 74 (21%) were in the WL group. The operative times in the WL group averaged 10 minutes longer than in the no-WL group ( P = .022). The mean length of stay was not significantly different between the 2 groups. Of the 353 patients, 262 (74%) completed 1 year of follow-up. The mean net postoperative weight loss was not significantly different between the 2 groups. The no-WL patients had a greater percentage of excess postoperative weight loss than the WL group (74% versus 66%; P = .01). Net complications occurred less frequently in the WL group ( P = .035). Conclusion Preoperative weight loss did not decrease the operative times or the length of stay. Preoperative weight loss increased neither the mean net postoperative weight loss nor the percentage of excess postoperative weight loss at 1-year follow-up. However, the WL group had fewer net complications.

P86: Can advanced laparoscopic fellowship programs be established without compromising the center’s outcomes?

Advanced laparoscopic fellowships have been touted as ideal formats for laparoscopic gastric bypass (LGB) training. Impact of such fellowships on center outcomes remains unknown. We assess here our fellowship program’s impact on LGB outcomes.

Early U.S. outcomes of laparoscopic gastric bypass versus laparoscopic adjustable silicone gastric banding for morbid obesity

Laparoscopic gastric bypass (LGBP) is the gold standard operation for long-term weight control in the United States. Laparoscopic adjustable silicone gastric banding (LASGB) is the preferred operative method for morbid obesity worldwide. Limited data are available comparing the two procedure in the United States. This study compares weight loss, complications, and early outcome of comorbidity resolution in patients who underwent LGBP versus LASGB. A review of prospectively collected data was performed on 392 patients undergoing primary LGBP (n = 232) and LASGB (n = 160) procedures between February 2001 and July 2004. Differences in percentage excess weight lost (%EWL) at 3, 6, 12, 18, and 24 months postop, improvement or resolution of comorbidities, and complications across procedure types were evaluated. Mean initial body mass index between groups was not significantly different (LGBP 47.2 vs LASGB 47.1, p < 0.53). There were significant differences in age, gender, and self-reported sweet-eating behavior between operative groups. There was a significantly greater %EWL in patients who underwent LGBP compared to patients of the LASGB groups 3, 6, 12, and 18 months after surgery. There were no significant differences in resolution or improvement of comorbidities between the groups. Although LGBP patients experienced more complications compared to LASGB patients (5.6 vs 4.3%, respectively; p < 0.56), this did not reach statistical significance. Early after surgery, LGBP patients lose more weight than LASGB patients but have similar improvements in comorbidities. Further follow-up is needed to determine the relative long-term efficacy of these procedures.

Training of a Minimally Invasive Bariatric Surgeon: Are Laparoscopic Fellowships the Answer?

Fellowships in advanced laparoscopy with emphasis in laparoscopic gastric bypass (LGBP) are available for obtaining experience in performing LGBP. The following is the first report in the literature prospectively documenting a single surgeon's experience with LGBP outcomes following completion of an advanced laparoscopic surgical fellowship. Outcomes measured prospectively included length of stay, length of operation, complications, reduction in obesity-related co-morbidities, and percentage excess weight loss. Outcomes were analyzed by quartile to see if there was difference over time. Complications were also compared to outcomes in the literature. 175 patients (147 female, 28 male) underwent LGBP. The mean BMI was 49.2. Mean operative time was 123 minutes, and mean length of stay was 2.2 days. The percentage excess weight loss at 1 year was 73% (n = 79). One patient developed an internal hernia (0.6%) and 1 patient developed an anastomotic leak (0.6%). Post operative transfusion rate was 4.6%. There were no deep venous thromboses or pulmonary emboli detected. There were no conversions to open, and there was no mortality. Upon quartile analysis, there was no difference in complication rates. Complication rates were comparable to published outcomes in the literature. Fellowships in advanced laparoscopy with emphasis on LGBP provide the optimal training environment for acquisition of skills necessary to safely and effectively perform LGBP. With fellowship training, complication rates were comparable to published outcomes in the literature without a period of higher complications (the learning curve).
