BAROS results in 700 patients after laparoscopic Roux-en-Y gastric bypass with subset analysis of age, gender, and initial body mass index

Five-Year BAROS Score Outcomes for Roux-en-Y Gastric Bypass, One Anastomosis Gastric Bypass, and Sleeve Gastrectomy: a Comparative Study

PURPOSE

Metabolic and bariatric surgery (MBS) has been shown to enhance the quality of life (QoL) in individuals with obesity. The Bariatric Analysis and Reporting Outcome System (BAROS) is a highly reliable scoring system utilized to assess weight loss, obesity-associated medical conditions, and QoL following MBS. This study aimed to assess the efficacy of sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), and one anastomosis gastric bypass (OAGB) in improving health outcomes for individuals with severe obesity, employing the BAROS questionnaire.

METHODS

A retrospective study was conducted, enrolling 299 patients with a body mass index (BMI) of 40 or higher who had undergone primary MBS (RYGB, OAGB, or SG) and had a 5-year follow-up. Patients were evaluated using the BAROS scoring system, which included measures of % excess weight loss (%EWL), improvement and remission of obesity-related medical problems, and postoperative short-term and long-term complications.

RESULTS

The mean age and pre-op BMI of the patients was 39.4 ± 9.4 years and 44.6± 6.5 kg/m2, respectively. The total BAROS score was significantly higher in patients who underwent OAGB compared to those who underwent RYGB and SG (P, 0.02). However, no significant differences were observed in other aspects of the BAROS score, such as QoL.

CONCLUSION

This study demonstrated that all three common metabolic and bariatric surgical procedures (SG, RYGB, and OAGB) significantly improved the QoL after surgery. Furthermore, patients who underwent OAGB had a significantly higher total BAROS score at the 5-year follow-up compared to those who underwent RYGB and SG.

Long-Term Quality of Life Outcomes After Laparoscopic Sleeve Gastrectomy and Roux-en-Y Gastric Bypass-a Comparative Study

Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) have been shown to improve metabolic comorbidities as well as quality of life (QoL) in the obese population. The vast majority of previous studies have investigated the metabolic effects of bariatric surgery and there is a dearth of studies examining long-term QoL outcomes post bariatric surgery. The outcomes of 43 patients who underwent bariatric surgery were prospectively assessed, using BAROS questionnaires to quantify QoL and metabolic status pre-operatively, at 1 year and at 8 years. Total weight loss and comorbidity resolution were similar between RYGB and SG. The RYGB cohort experienced greater QoL improvement from baseline and had higher BAROS scores at 8 years. RYGB may provide more substantial and durable long-term benefits as compared to SG.

Long-term BAROS scores and independent obesity-related co-morbidity predictors of failure after laparoscopic Roux-en-Y gastric bypass

BACKGROUND

Long-term (>5 yr) studies assessing outcomes after laparoscopic Roux-en-Y gastric bypass (LRYGB) using the Bariatric Analysis and Reporting Outcome System (BAROS) are limited. Evidence of predictors of failure long-term after LRYGB is also lacking.

OBJECTIVES

To compare BAROS scores at 5 and 10 years post LRYGB and to establish whether individual obesity-related co-morbidities are associated with suboptimal outcomes at these time points.

SETTING

Single bariatric unit.

METHODS

BAROS scores were analyzed in patients who were 5 years (group A) and 10 years (group B) post LRYGB. Obesity-related co-morbidities as predictors of failure of surgery (defined by % excess weight loss [%EWL] <50% or BAROS total score ≤1) were examined. Intergroup comparative analysis of outcomes and logistic regression modeling to determine predictors of weight loss failure were conducted.

RESULTS

A total of 88 patients were 5 years post LRYGB (group A), and 91 patients were 10 years post LRYGB (group B). A total of 52.3% (46/88) in group A and 54.9% (50/91) in group B had failure of weight loss defined by %EWL <50%. There were no significant differences in percentage of total weight loss, %EWL, or BAROS scores between the 2 groups (21.8% versus 22.0%, P = .897; 48.5% versus 47.1%, P = .993; and 3.7 versus 3.3, P = .332, respectively). No individual obesity-related co-morbidity at time of surgery was associated with suboptimal outcomes (%EWL <50% or BAROS total score ≤1) at 5 years or 10 years after LRYGB.

CONCLUSIONS

Long-term outcomes assessed by the BAROS score appear sustainable between 5 and 10 years after LRYGB surgery, and weight loss achieved at 5 years is maintained at 10 years. Preoperative presence of specific obesity-related co-morbidities was not associated with failure of surgery long-term.

Duodenal Switch Is Superior to Gastric Bypass in Patients with Super Obesity when Evaluated with the Bariatric Analysis and Reporting Outcome System (BAROS)

Background

It is not clear which bariatric procedure that gives the best outcome for patients with super obesity (body mass index [BMI] > 50 kg/m²). This study aims to compare outcomes in patients with super obesity after Roux-en-Y gastric bypass (RYGB) and duodenal switch (BPD/DS) using the Bariatric Analysis and Reporting Outcome System (BAROS) and a local questionnaire for gastrointestinal symptoms.

Methods

A retrospective mail survey including 211 patients, 98 RYGB and 113 BPD/DS, with a mean follow-up time of 4 years for both groups. Gender distribution, age, and comorbidities were similar. Weight loss, changes in comorbidities, quality of life (QoL), and adverse events were registered, as well as gastrointestinal symptoms.

Results

Preoperative BMI was higher in the BPD/DS group (56 ± 6.7 vs. 52 ± 4.0 kg/m², p < 0.01); despite this, the postoperative BMI was lower (31 ± 5.5 vs. 36 ± 7.1 kg/m², p < 0.01). The effect on diabetes was superior after BPD/DS; otherwise, both groups had a similar reduction in comorbidities. There was no difference in QoL. Adverse events were less common after RYGB (14 vs. 27%). Overall, the BPD/DS group had a superior BAROS score (4.7 ± 2.0 vs. 4.0 ± 2.1, p < 0.05). Dumping was more common after RYGB (p < 0.01), while reflux, diarrhea, fecal incontinence, and problems with malodorous flatus were more common after BPD/DS (all p < 0.05). Frequency of nausea/vomiting and abdominal pain were similar.

Conclusion

Patients with super obesity have a better weight reduction and metabolic control with BPD/DS, at the cost of higher incidence of adverse events, compared to patients operated with RYGB.

Quality of life after gastric sleeve and gastric bypass for morbid obesity

Highlights

Quality-of-life measures improve as early as 3 months after bariatric surgery.There is wide variability in reporting that renders direct comparisons difficult.The available comparisons between RYGB and sleeve gastrectomy could not detect any difference.Improvement in PRO measures might be related to weight loss.Larger and better designed studies are required to achieve discrimination in PRO measures.

Background

Obesity is associated with reduced quality-of-life (QoL), which generally improves after bariatric surgery. The differential effect of each type of surgery (gastric sleeve [SG] and gastric bypass [RYGB]) on QoL is not yet fully understood.

Objectives

To understand which of these surgeries offers greatest improvement in QoL and patient satisfaction.

Methods

Systematic literature search on Pubmed in July 2014. Relevant articles were selected in a step-wise approach. The 2482 titles were scanned for relevance and 191 were selected for abstract reviewing; and 88 papers were selected for full text analysis.

Results

Only 5 papers compared the 2 techniques and only 17 more had retrievable data either on SG or RYGB. The reports were very heterogeneous, preventing a direct comparison of patient reported outcomes (PRO) among studies.Improved results have been reported as early has 3 months and SF-36 scores were improved in all domains in medium to long-term. The question remains whether the improvement in QoL is related to the weight loss and which factors are associated with improved patients' perceptions.

Conclusions

There is wide heterogeneity in the reporting of PRO measures after bariatric surgery, but data is consistent with a significant improvement after both surgeries.Larger and better-designed studies are required to understand if there are significant differences in the quality of life after SG or RYGB.

Application of BAROS' questionnaire in obese patients undergoing bariatric surgery with 2 years of evolution

BACKGROUND:

-In recent decades, the high prevalence of obesity in the general population has brought serious concerns in terms of public health. Contrarily to conventional treatment involving dieting and physical exercising, often ineffective in generating long term results, bariatric opera-tions have been an effective method for sustained weight loss in morbidly obese individuals. The Bariatric Analysis and Reporting Outcome System (BAROS) is an objective and recognized system in the overall evaluation of results after bariatric surgery.

OBJECTIVE

- To investigate results concerning a casuistic of morbidly obese patients undergoing bariatric surgery over a 2-year follow-up in terms of weight loss, related medical conditions, safety and changes in quality of life.

METHODS

- A total of 120 obese (17 male and 103 female) patients, who underwent bariatric surgery, were assessed and investigated using the BAROS system after a 2- year follow-up.

RESULTS

- Patients obtained a mean excess weight loss of 74.6 (±15.9) % and mean body mass index reduction of 15.6 (±4.4) Kg/m2. Pre-surgical comorbidities were present in 71 (59%) subjects and they were totally (86%) or partially (14%) resolved. Complications resulting specifically from the surgical procedure were observed in 4.2% of cases (two bowel obstructions requiring re-operation, and three stomal stenosis treated with endoscopic dilation). Sixteen subjects (13% of total number of patients) presented minor clinical complications managed through outpatient care. The final scores for the BAROS questionnaire showcased excellent to good results in 99% of cases (excellent 44%, very good 38%, good 23%, acceptable 1%).

CONCLUSION

- According to the BAROS questionnaire, bariatric surgery is a safe and effective method for managing obesity and associated clinical comorbidities, allowing for satisfactory results after a 2-year follow-up. Future studies should address other clinical and psychosocial variables that impact outcome as well as allow for longer follow-ups.

Quality criteria in bariatric surgery: Consensus review and recommendations of the Spanish Association of Surgeons and the Spanish Society of Bariatric Surgery

Bariatric surgery has proven to be highly effective in controlling obesity and metabolic syndrome; the results of this surgery are not only expressed in terms of weight loss, but also in terms of resolution of comorbidities, improved quality of life and complications. The different parameters used to measure these outcomes require uniformity and reference patterns. Therefore, it is essential to identify those indicators and quality criteria that are helpful in defining the «best practice» principles in bariatric surgery. In this regard, the Section of Obesity of the Spanish Association of Surgeons, in collaboration with the Spanish Society for Bariatric Surgery (SECO), present as an objective to identify the key points that define «quality» in this type of surgery. We describe the main indicators based on the published literature as well as the criteria for referral of the main comorbidities according to the evidence found and grades of recommendation.

Quality of Life After Bariatric Surgery

INTRODUCTION AND PURPOSE

Morbid obesity together with obesity-related diseases has a negative impact on the quality of life. The aim of the study was to assess the quality of life amongst patients with morbid obesity as well as the impact of bariatric treatment on body weight and obesity-related diseases in addition to conducting an analysis of changes in the quality of life after surgical treatments, in the context of the surgical procedure type and degree of body weight loss.

MATERIAL AND METHODS

Sixty-five patients were treated for morbid obesity. The sample group consisted of 34 patients treated with laparoscopic sleeve gastrectomy (LSG) and 31 persons qualified for laparoscopic Roux-en-Y gastric bypass (LRYGB). The average body weight before the procedure was 146.2 kg. In the sample group, 89 % of persons qualified for the surgical treatments were diagnosed with hypertension and 52 % persons that were operated on were diagnosed with diabetes type 2 before the surgical procedure. Before commencement of the surgical treatment, the quality of life was assessed, which in both groups qualified for given types of bariatric procedures was considerably low.

RESULTS AND CONCLUSIONS

Percentage excessive weight loss (%EWL) was 58.8 %. No significant differences in body weight loss were noted between the two types of procedures. Improvement was observed in the treatment of obesity-related diseases. Also, the quality of life was enhanced significantly. No differences were noted in terms of the quality of life improvement between particular types of surgical procedures. No significant differences were observed during the analysis of body weight loss impact on the quality of life improvement.

Laparoscopic Roux-en-Y gastric bypass for morbid obesity: comparison of primary versus revisional bypass by using the BAROS score

BACKGROUND

Vertically banded gastroplasty or adjustable gastric banding often result in weight regain, complications, or side effects. Failed restrictive bariatric procedures can be converted in revisional laparoscopic Roux-en-Y gastric bypass (LRYGB). This study aimed to compare weight loss, evolution of comorbidities, and quality of life (QOL) between primary versus revisional LRYGB.

METHODS

Between 2004 and 2012, 374 patients underwent LRYGB as primary or revisional surgery performed by a single surgeon. Patient data were retrospectively reviewed; questionnaires of QOL were sent to all patients. Outcomes were evaluated according to Bariatric Analysis and Reporting Outcome System (BAROS) taking into account excess body mass index loss (EBMIL), correction of comorbidities, improvement in QOL, and complications.

RESULTS

Two hundred thirty-two patients (62%) responded to the questionnaire, 163 patients in the primary group and 69 in the revisional group. Median follow-up was 36 months (12-108). Median percentages of EBMIL were, respectively, 74% (26.8-126.8) and 50% (-31.6-124.2) in the primary and the revisional groups (p < 0.01). Median BAROS score reached 6.5 (-2-9) in the primary group, against 4.3 (-1.8-9) in the revisional group (p < 0.01). There were significantly less "fair" and more "excellent" scores in the primary group, considering initial BMI before gastroplasty. Arterial hypertension and sleep apnea syndrome resolved, respectively, in 51 and 56% in the primary group and only in 29 and 33% in the revisional group (p < 0.01).

CONCLUSIONS

According to BAROS score, revisional LRYGB for failed restrictive procedures provided poorer results than primary LRYGB in terms of weight loss, resolution of comorbidities and QOL.

Discharge disposition after bariatric surgery

Weight loss continues for extended time post-bariatric surgery; thus, discharge destination is an important factor to consider when examining outcomes of surgery. The Agency for Healthcare Research and Quality State Inpatient Database was utilized to identify patients with bariatric surgery and to determine factors associated with and predictive of home discharge. Patients that were discharged home had shorter length of stays, lower total hospital costs, fewer chronic conditions, and lower readmission rates. Factors predictive of discharge were identified. Being discharged home could be associated with characteristics vital to patient's long-term weight loss. It is imperative to focus on factors predictive of home discharge in order to reap the most beneficial outcomes of surgery.

Impact of Bariatric Surgery on Patients from Goiás, Brazil, Using the BAROS Method - A Preliminary Study

Introduction

As obesity is currently a major public health problem, bariatric surgery has been widely indicated due to the difficulties involved in the clinical management of obese adults.

Objectives

Assess the quality-of-life (QOL) of patients who had undergone Roux-en-Y Gastric Bypass (RYGB) in the State of Goiás, Brazil, where as yet no studies have been published on the QOL of patients who underwent bariatric surgery.

Methods

A retrospective study, using the Bariatric Analysis and Reporting Outcome System (BAROS), was carried out in Goiânia and Rio Verde, Goiás, Brazil, with 50 over 18-year-old patients of both genders, who had undergone RYGB and had at least three months of postoperative time.

Results

Before RYGB, 48% of the individuals were classified as morbidly obese. Average weight and body mass index (BMI) of the 50 patients interviewed were 119.37 ± 18.44 kg and 43.54 ± 5.33 kg/m², respectively. By contrast, after the RYGB these parameters decreased significantly to 78.01 ± 11.06 kg and 28.46 ± 3.61 kg/m², respectively, mainly from the 3rd to 85th month of postoperative time (p < 0.0001). As well as that, 78% reported having presented preoperative comorbidities, especially hypertension (44%), rheumatism (34%), dyslipidemia (24%) and diabetes (20%). However, after surgery, the resolution rates were 77, 24, 100 and 100%, respectively, for these same clinical conditions. In terms of QOL, some patients reported feeling better (8%) or much better (92%) after RYGB. The outcome of the BAROS method for those patients was classified as fair (2%), good (8%), very good (24%) and excellent (66%).

Conclusions

Preliminary results indicated that RYGB could be a successful surgical procedure to promote satisfactory and sustained reduction in the body measurements of morbidly obese patients from Goiás, Brazil. Furthermore, the final BAROS score showed improvements in associated comorbidity and also in the QOL of these patients.

Nutritional repercussions in patients submitted to bariatric surgery

BACKGROUND

Few studies evaluated the association between nutritional disorders, quality of life and weight loss in patients undergoing bariatric surgery.

AIM

To identify nutritional changes in patients undergoing bariatric surgery and correlate them with weight loss, control of comorbidities and quality of life.

METHOD

A prospective cohort, analytical and descriptive study involving 59 patients undergoing bariatric surgery was done. Data were collected preoperatively at three and six months postoperatively, evaluating nutritional aspects and outcomes using BAROS questionnaire. The data had a confidence interval of 95%.

RESULTS

The majority of patients was composed of women, 47 (79.7%), with 55.9% of the series with BMI between 40 to 49.9 kg/m(²). In the sixth month after surgery scores of quality of life were significantly higher than preoperatively (p<0.05) and 27 (67.5 %) patients had comorbidities resolved, 48 (81.3 %) presented BAROS scores of very good or excellent. After three and six months of surgery 16 and 23 presented some nutritional disorder, respectively. There was no relationship between the loss of excess weight and quality of life among patients with or without nutritional disorders.

CONCLUSION

Nutritional disorders are uncommon in the early postoperative period and, when present, have little or no influence on quality of life and loss of excess weight.

Outcomes of revisional procedures for insufficient weight loss or weight regain after Roux-en-Y gastric bypass

BACKGROUND

The Roux-en-Y gastric bypass (RYGB) performed laparoscopically (LRYGB) is the most frequently performed bariatric procedure in Belgium. However, late results in terms of weight loss or weight regain are inconsistent and may warrant a second procedure. This retrospective study analyzes the laparoscopic options for revisional surgery after LRYGB.

METHODS

Between January 1, 2001 and December 31, 2009, 70 patients underwent a new laparoscopic procedure for poor weight loss or weight regain after LRYGB. The revisional procedure was performed a median of 2.6 years after the initial bypass operation. Fifty-eight patients were available for follow-up (82.9 %); 19 underwent distalization; and 39 a new restrictive procedure.

RESULTS

The mean mass index (BMI) before the revisional procedure was 39.1 + 11.3 kg/m(2) (30.8-51.8), down from 42.7 + 19.7 kg/m(2) (33.0-56.6) initially, which corresponded to a percentage of excess weight loss (EWL) of 12.4 + 9.3 % (-1.0-29.1). After the corrective procedure, with a follow-up of approximately 4 years, mean BMI was 29.6 + 12.4 kg/m(2) (18.0-45.5), for a significant additional percentage of EWL of 53.7 + 9.8 % (2.0-65.8). The overall complication rate was 20.7 %, and the reoperation rate was 7.3 %. The overall leak rate was 12.1 %. Patients suffering from leaks could consistently be treated conservatively or by stent placement. Two patients needed reconversion after distal bypass. The satisfaction index was good in just over 50 % of the patients.

CONCLUSION

Revisional laparoscopic surgery after RYGB performed for weight issues provides good additional weight loss but carries significant morbidity. Leaks can usually be handled non-surgically. Patient satisfaction is only fair.

Sexual hormones and erectile function more than 6 years after bariatric surgery

BACKGROUND

The long-term effect of bariatric intervention on androgenic hormones and erectile function is not well known. In a prospective comparative study, the profile of sexual function was ascertained. The setting was a large public academic hospital.

METHODS

A total of 51 patients were included in the present study. Of these, 23 were in the bariatric surgery cohort (with 6-14 yr of follow-up), 14 were obese controls, and 14 were lean controls, aged 30-65 years. The groups were matched for age and, in the case of obese controls, the current body mass index. The measurements included orchidometry, an assessment of gynecomastia, the International Index of Erectile Function, the Aging Males Symptoms questionnaire, the measurement of 12 hormones, and general biochemical measurements.

RESULTS

Bariatric patients lost substantial weight (59.8 ± 12.1 versus 35.1 ± 7.7 kg/m(2)), albeit residual obesity was the rule, with varying degrees of sleep apnea, hypertension, and glucose/lipid aberrations. The total and free testosterone and sex hormone-binding globulin levels were greater in the gastric bypass patients than in the obese controls and comparable to those of lean individuals. The International Index of Erectile Function final score revealed no differences; however, the domains of erectile dysfunction (P = .015) and overall satisfaction (P = .028) were better than those in the obese controls, although still lower than those in the lean group. The correlation between the body mass index and the International Index of Erectile Function score in the entire population (n = 51) was negative, as expected, with, however, low r and r(2) indexes (.354 and .125, respectively).

CONCLUSION

The findings are consistent with long-term normalization of androgenic hormones but less than complete normalization of erectile function. This seeming contradiction might be explained by the remaining or relapsing obesity or its co-morbidities.
