Bariatric surgery ameliorates  obesity‐associated diseases  , result ing in psychological and social benefits . Long‐term studies of its effects on quality of life ( QOL ) assessed with well established instruments are lacking . This prospect i ve study investigated the long‐term effects of  gastric b and ing  on health‐related QOL using an obesity‐specific vali date d measure BACKGROUND There is a lack of adequate prospect i ve data on quality -of-life ( QOL ) and its predictors in patients undergoing laparoscopic sleeve gastrectomy ( LSG ) .  The aim of this study was to assess longitudinal changes in QOL after LSG with the use of the obesity-specific Moorehead-Ardelt II question naire ( MAII ) and to identify clinical parameters associated with QOL outcome . METHODS Morbidly obese patients consecutively admitted for LSG , over a 30-month period , were prospect ively studied . QOL was assessed using the vali date d Greek version of the MAII question naire and a visual analogueue scale ( VAS ) , preoperatively and at 6 , 12 , and 24 months postoperatively . Anthropometric data and obesity-related co-morbidities were recorded . RESULTS A total of 111 patients with a mean age 36.8±9.2 years were included . Mean preoperative body mass index ( BMI ) was 49.1±7.5 kg/m2 . Percentage excess BMI loss ( % EBL ) was 51.1±14.9 , 64.2±17.9 and 66.4±18.0 at 6 , 12 , and 24 months , respectively . Postoperatively , all obesity-related co-morbidities were significantly improved . MAII score increased from -.40±1.30 preoperatively to 1.75±.83 , 2.18±.80 , and 1.95±.71 at 6 , 12 , and 24 months postoperatively ( trend P<.001 ) . Preoperative median ( interquartile range ) VAS was 3 ( 1 ) increasing to 9 ( 2 ) , 10 ( 1 ) , and 9 ( 1 ) at 6 , 12 , and 24 months postoperatively ( P<.001 ) . % EBL and reduction in obesity-related co-morbidities , especially resolution of diabetes and sleep apnea , correlated significantly with higher QOL during the course of the study . CONCLUSION LSG , a safe and effective bariatric operation , results in sustained weight loss and significant improvements in QOL . Both weight loss and amelioration of co-morbidities contribute to higher level of postsurgical QOL BACKGROUND The increase in obesity coupled with greater acceptance of the field of bariatric surgery has result ed in a substantial rise in the number of weight-loss operations . Because obese individuals are at high risk for surgical complications , concern about the safety of bariatric procedures exists . Earlier investigations of the clinical features associated with surgical complications have produced conflicting results . We sought to identify risk factors for surgical complications in a large , nationally representative population of US veterans . STUDY DESIGN We analyzed data  on bariatric procedures performed at 12 Veterans ' Affairs medical centers approved to perform weight-loss operations between 1998 and 2004 . Detailed pre- , intra- , and postoperative information and longterm mortality data were prospect ively collected using the National Surgical Quality Improvement Program methodology . We used multivariable logistic regression to identify clinical features associated with postoperative complications . RESULTS Among 575 bariatric patients assessed between 1998 and 2004 , 74 % were men with a mean age of 51 years . Thirty-day mortality was 1.4 % . Overall complication rate was 19.7 % . Of those with complications , one-half were of considerable clinical importance , as they were associated with prolonged length of stay . Clinical features that were predictive of adverse events in our multivariable analyses were superobesity , weight>350 pounds , and smoking . A more than 20 pack-year history of smoking was also associated with difficulty in weaning from a ventilator postoperatively . CONCLUSIONS We identified smoking and superobesity as preoperative risk factors associated with postoperative complications . Future studies should examine the effect of preoperative weight loss and smoking cessation on bariatric procedure outcomes Quality of life improves after  bariatric surgery .  However , long-term results and the influence of reoperations are not well known . A prospect i ve quality of life assessment before , 1 and 7 years after  laparoscopic adjustable gastric b and ing ( LAGB ) and vertical b and ed gastroplasty ( VBG )  was performed in order to determine the influence of reoperations during follow-up . One hundred patients were included in the study . Fifty patients underwent VBG and 50 LAGB .  Patients completed the  quality of life question  naires prior to surgery and two times during follow-up . Health-related quality of life ( HRQoL ) question naires included the Nottingham Health Profile I and II and the Sickness Impact Profile 68 . Follow-up was 84 % with a mean duration of 84 months ( 7 years ) . During follow-up , 65 % of VBG patients underwent conversion to Roux-en-Y gastric bypass while 44 % of LAGB patients underwent a reoperation or conversion . One year after the procedure , nearly all quality -of-life parameters significantly improved . After 7 years , the Nottingham Health Profile (NHP)-I domain “ physical ability ” , the NHP-II and the SIP-68 domains “ mobility control ” , “ social behavior ” , and “ mobility range ” were still significantly improved in both groups . The domains “ emotional reaction ” , “ social isolation ” ( NHP-I ) , and “ emotional stability ” ( SIP-68 ) remained significantly improved in the VBG group while this was true for the domain “ energy level ” ( NHP-I ) in the LAGB group . Both the type of procedure and reoperations during follow-up were not of significant influence on the HRQoL results . Weight loss and decrease in comorbidities were the only significant factors influencing quality of life . Restrictive bariatric surgery improves quality of life . Although results are most impressive 1 year after surgery , the improvement remains significant after long-term follow-up . Postoperative quality of life is mainly dependent on weight loss and decrease in comorbidities and not on the type of procedure or surgical complications OBJECTIVE To assess the impact of surgical treatment on health-related quality of life ( QoL ) and its various dimensions in four common gastrointestinal diseases , to compare it with that of the general population , and to assess the relationship between the patient 's and the surgeon 's satisfaction . DESIGN Prospect i ve , observational study . SETTING Tertiary care centre , Finl and . PATIENTS 131 patients , of whom 77 had cholecystectomy , 20 fundoplication , 20 incisional herniorrhaphy , 12 large bowel resection , and 2 construction of a stoma only because of unresectable colorectal cancer . INTERVENTIONS Routine operative treatment of four gastrointestinal diseases . MAIN OUTCOME MEASURES QoL measured by a  generic 15-dimensional instrument .  RESULTS The health-related QoL improved postoperatively in the entire group . Discomfort , symptoms , and vitality were all reduced at 2 months , whereas bowel movements , eating , and usual activities had been restored at 12 months . The health related QoL was comparable with that of the general population at 12 months except for breathing and sleeping . The pattern of recovery varied among diagnostic subgroups , being most improved in patients operated on for biliary disease , those aged 60 years or younger , women and otherwise previously healthy patients . There was a close agreement between the patient 's and the surgeon 's opinion of outcome . CONCLUSIONS Gastrointestinal surgery improves quality of life . Separating a generic health-related QoL measure into dimensions allows a more appropriate estimation of quality of life than a single index score . Because some dimensions were made worse soon after operation and some were restored slowly , a minimum 12-month follow-up may be needed to assess the effect of gastrointestinal surgery on health- related BACKGROUND Surgery remains the most effective intervention for obesity and its comorbidities . However , the long-term efficacy of bariatric procedures is rarely reported . This study addresses operative trends , efficiency , and long-term outcomes from a large bariatric program . STUDY DESIGN Data were prospect ively collected on 3,460 patients undergoing 3,503 operations from January 2004 to March 2013 . Primary procedures included  Roux-en-Y gastric bypass  ( RY ; n = 2,966 ) , adjustable b and ( AB ; n = 352 ) , and sleeve gastrectomy ( SG ; n = 118 ) . There were 67 revisional procedures ( RP ) . Mean operative time , hospital length of stay , major 30-day morbidity/mortality , follow-up compliance , and weight loss per procedure at follow-up were recorded . RESULTS Mean operative times decreased to the following : RY , 53 minutes ; AB , 35 minutes ; SG , 46 minutes ; and RP , 71 minutes . Mean length of stay was reduced to the following : RY , 1.53 days ; AB , 0.97 days ; SG , 2.12 days ; and RP , 2.68 days . Major complications were mortality , 0.09 % ; leak , 0.51 % ; bleed , 2.37 % ; pneumonia , 0.63 % ; venous thromboembolism , 0.40 % ; and reoperation , 2.34 % . The complication rate was lowest for AB and highest for SG ( p < 0.05 ) . Adjustable b and was the initial procedure in 73 % of cases requiring RP . Follow-up compliance was 93 % at 1 year , 79 % at 3 years , 71 % at 5 years , and 33 % at 9 years . Adjustable b and offered significant weight loss at 1 and 3 years ( p < 0.0001 ) , but less than RY or SG ( p < 0.0001 ) . Excess weight loss was not significantly different between RY and SG at 1 year . Significant weight loss with RY persisted at 7 to 9 years ( p < 0.0001 ) . CONCLUSIONS Our bariatric program experienced an increase in SG and RP and a decrease in AB . Optimization of care reduced operative time and length of stay . All procedures achieved significant weight loss in the first year . Adjusted b and had the lowest morbidity , but inferior weight loss and greater need for revision . Long-term weight-loss data are only available for RY Background Negative consequences of the obesity epidemic include decreased physical , psychological , and sexual health .  Bariatric surgery is a well-tolerated and effective treatment for morbid obesity . This study aim ed to determine the effect of bariatric surgery on health-related quality of life ( HRQOL ) and sexual functioning and to identify potential predictors of this effect . Methods Eighty morbidly obese patients ( 50 women ) completed the study .  HRQOL was measured using the Short Form 36 question naire ( SF-36 ) . Sexual functioning was assessed using the Female Sexual Functioning Index ( FSFI ) and the International Index of Erectile Function ( IIEF ) . All participants were evaluated four times as follows : presurgery ( T1 ) , 1 month ( T2 ) , 6 months ( T3 ) , and 1 year ( T4 ) after surgery . Results Body mass index ( BMI ) significantly decreased over time ( p < 0.001 ) . Apart from male orgasm , all sexual functioning components as well as all SF-36 sub-scales improved between T1 and T4 . The maximum improvement was observed between T2 and T3 . Baseline HRQOL scores correlated with postoperative improvement in all HRQOL components . BMI improvement was correlated with improvement in role physical , bodily pain , and mental health scores . Baseline total sexual satisfaction score independently predicted total satisfaction improvement in both genders . Conclusions The present findings indicate that bariatric surgery represents an effective obesity treatment , leading to significant BMI reduction and improvement in HRQOL and sexual functioning , especially in the first 6 months postoperatively The study objectives were to assess 2-year changes in health-related quality of life ( HRQL ) after gastric bypass in patients with severe obesity and to analyze HRQL improvements in relation to weight loss after bariatric surgery . This was a prospect i ve intervention study with consecutive patients referred to two bariatric surgical units in the Basque Country . We used both generic ( Short Form Health Survey , SF-36 and EuroQol , EQ-5D ) , and specific question naires ( Moorehead-Ardelt , MA II and Obesity-related Problems Scale , OP ) . Effect sizes and receiver operating characteristic ( ROC ) curves were calculated to assess the change in quality of life . Spearman ’s correlation coefficient was calculated to assess whether there was an association between changes in body mass index ( BMI ) and HRQL . Of 82 patients who underwent surgery , 79 were followed-up for 2 years . Mean weight loss was 37 % of body weight ( 49 kg ) and BMI fell from 50.6 to 31.8 . The initial problems and final improvements were greater in the physical dimensions . Considerable benefits were observed in assessment s with all the instruments used . However , the changes in weight/ BMI and HRQL were not linear . The comparison with general population showed a similar profile in SF-36 dimensions after surgery . Severely obese patients have lower perceived health across all dimensions of quality of life . Moreover , the impact on functioning is so important that severe obesity can be described as a cause of disability that disappears 2 years after surgical treatment . ROC curves indicate that most of the HRQL measures are poor predictors of change in terms of reduction in body weight or BMI OBJECTIVE The aim of this investigation was to assess the effect of malabsorptive bariatric surgery ( BS ) on the quality of life ( QoL ) , applying the Nottingham Health Profile ( NHP ) and the bariatric analysis and reporting outcome system ( BAROS ) . DESIGN A prospect i ve cohort study was performed in 100 adult patients ( > 18 years ) undergoing bariatric surgery by malabsorptive technique for one year . RESEARCH METHODS AND PROCEDURES Patients were monitored from the beginning of the BS program until a year after the intervention , applying the NHP and the BAROS test . At baseline , the mean weight of the women was 132 ± 22 kg and the Body Mass Index ( BMI ) was 50.7 kg/m² . RESULTS The values obtained from different areas applying the NHP question naire showed statistical significant differences ( p < 0.001 ) with respect to baseline values . According to the BAROS test , 48 % of patients lost 25 - 49 % of weight excess and 80.8 % had resolved major comorbidities at 1 yr . According to the Moorehead-Ardelt QoL score , there were major improvements in employment and self-esteem in 89 % and 87 % of patients , respectively , and improvements in physical activity , sexual and social relationships . According to the total mean BAROS score , the outcome was considered " very good " . CONCLUSION NHP and BAROS question naires appear to be useful and easily applicable tools to assess the QoL of obese patients BACKGROUND Improvements in health-related quality of life ( HR-QoL ) occur after  bariatric surgery .  However , sustainability of these changes over time remains debated . METHODS Data collected in a prospect i ve 3-year multicenter Italian study on changes of HR-QoL after laparoscopic adjustable gastric b and ing were used .  HR-QoL has investigated with the SF-36 question naire .  Hunger , satiety , and the self-perceived effects of LAGB were recorded . RESULTS A total of 230 patients ( 53 male and 177 female ) were analyzed . Body mass index was 41.4±5.4 kg/m2 at baseline , declined to 33.8±5.8 kg/m2 12 months after surgery ( P<.001 ) , and further reduced to 31.9±5.1 kg/m2 36 months after surgery ( P<.001 versus 12 months ) . Scores in the SF-36 subscales were lower than in the general Italian population at baseline . The physical component summary score was 51.9±11.6 at baseline , improved to 79.2±15.4 at 12 months ( P<.001 ) , and stabilized to 79.8±15.6 at 36 months . The mental summary score was 52.3±11.8 at baseline , improved to 75.2±17.3 at 12 months ( P<.001 ) , and stabilized to 74.2±17.5 at 36 months . A decline>10 points between 12 and 36 months in the summary scores was observed in 22.0 % of the patients for PCS and in 26.8 % for MCS . In a multiple linear regression analysis , deterioration in HR-QoL in the 12 - 36 months period was associated to the presence of better HR-QoL values at 12 months and to a more pronounced reduction of the self-perceived effect of the b and ing at 36 months . CONCLUSION Improvements in HR-QoL observed in the first year after surgery maintained up to the third year after gastric b and ing BACKGROUND Weight loss is associated with short-term amelioration and prevention of metabolic and cardiovascular risk , but whether these benefits persist over time is unknown . METHODS The prospect i ve , controlled Swedish Obese Subjects Study involved obese subjects who underwent gastric surgery and contemporaneously matched , conventionally treated obese control subjects . We now report follow-up data for subjects ( mean age , 48 years ; mean body-mass index , 41 ) who had been enrolled for at least 2 years ( 4047 subjects ) or 10 years ( 1703 subjects ) before the analysis ( January 1 , 2004 ) . The follow-up rate for laboratory examinations was 86.6 percent at 2 years and 74.5 percent at 10 years . RESULTS After two years , the weight had increased by 0.1 percent in the control group and had decreased by 23.4 percent in the surgery group ( P<0.001 ) . After 10 years , the weight had increased by 1.6 percent and decreased by 16.1 percent , respectively ( P<0.001 ) . Energy intake was lower and the proportion of physically active subjects higher in the surgery group than in the control group throughout the observation period . Two- and 10-year rates of recovery from diabetes , hypertriglyceridemia , low levels of high-density lipoprotein cholesterol , hypertension , and hyperuricemia were more favorable in the surgery group than in the control group , whereas recovery from hypercholesterolemia did not differ between the groups . The surgery group had lower 2- and 10-year incidence rates of diabetes , hypertriglyceridemia , and hyperuricemia than the control group ; differences between the groups in the incidence of hypercholesterolemia and hypertension were undetectable . CONCLUSIONS As compared with conventional therapy , bariatric surgery appears to be a viable option for the treatment of severe obesity , result ing in long-term weight loss , improved lifestyle , and , except for hypercholesterolemia , amelioration in risk factors that were elevated at baseline Background Patients undergoing bariatric surgery  generally report improved work performance after this procedure ; however , previous research has been limited by a lack of st and ardized employment measures and a failure to account for the impact of psychiatric illness on employment outcomes . To address these limitations , this study aims to assess changes in patients ’ employment impairment and productivity 12 months post-surgery and to identify psychosocial predictors of change in employment outcomes . Methods A total of 164 patients underwent bariatric surgery between February 2010 and November 2012 in this prospect i ve cohort study . The primary outcome was a change in employment impairment ( EI ) as measured by total Lam Employment Absence and Productivity Scale ( LEAPS ) scores and changes in participants ’ job status category . Multiple linear regression models assessed whether baseline demographic or clinical factors , including a history of psychiatric illness and changes in depressive , anxiety and quality of life ( QOL ) symptoms , were associated with a change in LEAPS scores . Results Participants reported a significant reduction in EI post-surgery ( p < 0.0001 ) and improvement in work productivity ( p < 0.0001 ) 12 months after surgery . Only changes in depression ( confidence interval ( CI ) 0.46 , 0.76 , p < 0.0001 ) , anxiety ( CI 0.49 , 0.85 , p < 0.0001 ) and mental QOL ( CI −0.30 , −0.17 , p < 0.0001 ) were significant predictors of change in EI total scores . Logistic regression analysis did not identify significant predictors of change in participant job status . Conclusions Patients with pre-bariatric surgery psychiatric distress are more likely to report greater employment impairment and worse employment productivity pre-surgery . These patients also experience the greatest improvements in post-surgery employment functioning Background Bariatric surgery is currently the most effective form of obesity management for those whose BMI is greater than 40 ( or 35 with co morbidities ) . A minority of patients , however , either do not show the desired loss of excess weight or show weight regain by follow up . Research highlights some of the reasons for this variability , most of which centres on the absence of any psychological support with patients describing how although surgery fixes their body , psychological issues relating to dietary control , self esteem , coping and emotional eating remain neglected . The present study aims to evaluate the impact of a health psychology led bariatric rehabilitation service ( BRS ) on patient health outcomes . The bariatric rehabilitation service will provide information , support and mentoring pre and post surgery and will address psychological issues such as dietary control , self esteem , coping and emotional eating . The package reflects the rehabilitation services now common place for patients post heart attack and stroke which have been shown to improve patient health outcomes . Methods / Design The study is a r and omised control trial and patients will be allocated to receive either usual care or the bariatric rehabilitation service pre and post bariatric surgery . Follow up measures of weight loss and psychological issues will be taken at baseline ( 2 weeks preoperatively ) , 3 , 6 and 12 months postoperatively . The contents of the bariatric service and the follow up measures are based on previous pilot work and have been developed further by the research team working closely with two patient support groups ( BOSPA & WLSinfo ) . This study will take place in St Richard 's Hospital in Chichester in the UK . Discussion It is predicted that a bariatric rehabilitation service will improve weight loss following surgery and will also facilitate changes in other psychological variables such as quality of life , dietary control , self esteem , coping and emotional eating . This also has cost implication s for the NHS and other healthcare providers as improved effectiveness of bariatric surgery reduces the health costs of obese patients in the longer term . Trial registration Clinical Trials.gov NCT01264120 BACKGROUND Although bariatric surgery is associated with significant overall weight loss , many patients experience suboptimal outcomes . Our objective was to document the preliminary efficacy of a behavioral intervention for bariatric surgery patients with relatively poor long-term weight loss and to explore the factors related to outcome at an academic medical center in the United States . METHODS Patients with a body mass index ( BMI ) ≥ 30 kg/m(2 ) who had undergone bariatric surgery ≥ 3 years before study entry and had < 50 % excess weight loss were enrolled . The participants were r and omly assigned to a 6-month behavioral intervention or wait list control group . The assessment s were conducted at baseline ( before intervention ) and 6 months ( after intervention ) and 12 months ( 6-mo follow-up ) . RESULTS On average , the participants ( n = 36 ) had undergone surgery 6.6 years before study entry . The average age was 52.5 ± 7.1 years , and the BMI was 43.1 ± 6.2 kg/m(2 ) ; most participants were women ( 75 % ) and white ( 88.9 % ) . The intervention patients had a greater percentage of excess weight loss than did the wait list control group at 6 ( 6.6 % ± 3.4 % versus 1.6 % ± 3.1 % ) and 12 ( 5.8 % ± 3.5 % versus .9 % ± 3.2 % ) months . However , the differences were not significant and the results varied . The intervention patients with more depressive symptoms ( P = .005 ) and less weight regain before study entry ( P = .05 ) experienced a greater percentage of excess weight loss . CONCLUSION Behavioral intervention holds promise in optimizing long-term weight control after bariatric surgery . More research is needed on when to initiate the intervention and to identify which patients will benefit from this type of approach The purpose of this study was to determine whether pre- to postoperative increases in physical activity ( PA ) are associated with weight loss and health-related quality of life ( HRQoL )  following bariatric surgery . Participants were 199 Roux-en-Y gastric bypass ( RYGB ) surgery patients . The International Physical Activity Question naire ( IPAQ ) was used to categorize participants into three groups according to their preoperative and /1-year postoperative PA level : ( i ) Inactive/Active ( < 200-min/week/>or=200-min/week ) , ( ii ) Active/Active ( > or=200-min/week/>or=200-min/week ) and ( iii ) Inactive/Inactive ( < 200-min/week/<200-min/week ) . The  Medical Outcomes Study Short Form-36 ( SF-36 ) was used to assess HRQoL. Analyses of covariance were conducted to examine the effects of PA group on weight and HRQoL changes . Inactive/Active participants , compared with Inactive/Inactive individuals , had greater reductions in weight ( 52.5 + /- 15.4 vs. 46.4 + /- 12.8 kg ) and BMI ( 18.9 + /- 4.6 vs. 16.9 + /- 4.2 kg/m(2 ) ) . Weight loss outcomes in the Inactive/Active and Active/Active groups were similar to each other . Inactive/Active and Active/Active participants reported greater improvements than Inactive/Inactive participants on the mental component summary ( MCS ) score and the general health , vitality and mental health domains ( P < 0.01 ) . Although the direction of causation is not clear , these findings suggest that RYGB patients who become active postoperatively achieve weight losses and HRQoL improvements that are greater than those experienced by patients who remain inactive and comparable to those attained by patients who stay active . Future r and omized controlled trials should examine whether assisting patients who are inactive preoperatively to increase their PA postoperatively contributes to optimization of weight loss and HRQoL outcomes Background : The Bariatric Quality of Life Index ( BQL ) was created and vali date d as a nine-factor model in 2005 for the measurement of quality of life (QoL)in  patients before and after bariatric surgery .  Even though the results were acceptable , the statistical structure of the test was very unclear . Methods : A total·f466 patients were enrolled in an ongoing prospect i ve longitudinal German study . The assessment took place preoperatively and at 1 , 3 , 6 , 9 , and 12 months postoperatively . After that period , reevaluations were done on a yearly basis . In addition to demographic and clinical data , QoL data were collected using the  BQL  , the Short Form12 ( SF-12v2 ) , the Gastrointestinal Quality of Life Index ( GIQLI ) , and the  Bariatric Analysis and Reporting Outcome System  ( BAROS ; old version since the study started in 2001 ) . Statistical parameters for contingency ( Cronbach ’s Α),construct and criterion validity ( Pearson ’s r ) , and responsiveness ( st and ardized effect sizes ) were calculated . The data of the assessment s conducted preoperatively and after 6 and 12 months were used for the validation . Results : The factor analysis and the screeplot showed that a one-factor solution explained 45.37%of variance . The selectivity of the items ranged between 0.61 and 0.85 , and Cronbach ’s Α was 0.898 . The measurements showed similar excellent results with the analysis of all measurement points . Pearson ’s test showed a good retest reliability ( r = 0.9 ) . The correlations with the SF-12 and the Moorehead-Ardelt I question naire ( MA-I ) were significant , while the correlation with the GIQLI was low . The results of the correlation with the excess weight loss (EWL)(0.45 and 0.49 ) and the BMI ( –0.38 and –0.47 ) were good . Conclusion : The BQL is a valid instrument and should be preferred over generic question naires as it provides betterresponsiveness To evaluate influence of laparoscopic gastric b and ing ( LGB ) on quality of life ( QOL ) in patients with morbid obesity .  Laparoscopic adjustable gastric b and ing is a popular bariatric operation in Europe . The objectives of surgical therapy in patients with morbid obesity are reduction of body weight , and a positive influence on the obesity-related comorbidity as well the concomitant psychologic and social restrictions of these patients . In a prospect i ve clinical trial , development of the individual patient QOL was analyzed , after LGB in patients with morbid obesity . From October 1999 to January 2001 , 152 patients [ 119 women , 33 men , mean age 38.4 y ( range 24 to 62 ) , mean body mass index 44.3 ( range 38 to 63 ) ] underwent evaluation for LGB  according the following protocol : history of obesity ; concise counseling of patients and relative on nonsurgical treatment alternatives , risk of surgery , psychologic testing , question naire for eating habits , necessity of lifestyle change after surgery ; medical evaluation including endocrinologic and nutritionist work-up , upper GI endoscopy , evaluation of QOL using the Gastro Intestinal Quality of Life Index ( GIQLI ) . Decision for surgery was a multidisciplinay consensus . This group was follow-up at least 2 years , focusing on weight loss and QOL . Mean operative time was 82 minutes ; mean hospital stay was 2.3 days and the mean follow-up period was 34 months . The BMI dropped from 44.3 to 29.6 kg/m2 and all comorbid conditions improved markedly : diabetes melitus resolved in 71 % of the patients , hypertension in 33 % , and sleep apnea in 90 % . However , 26 patients ( 17 % ) had late complications requiring reoperation . Preoperative global GIQLI score was 95 ( range 56 to 140 ) , significant different of the healthy volonteers score ( 120 ) ( 70 to 140 ) P<0.001 . Correlated with weight loss ( percentage loss of overweight and BMI ) , the global score of the group increased to 100 at 3 months , 104 at 6 , 111 at 1 year to reach 119 at 2 years which is no significant different of healthy patients . Analyzing the subscale , physical condition , emotional status , and social integration increased significantly ( P<0.001 ) from preoperative to end of follow-up . Digestive symptoms were not modified . In case of failure of the procedure ( 10.5 % ) global Giqli score is not modified . Patients who have required successfull revisional surgery for late complications ( 6.5 % ) have an excellent QOL outcome that are not different from the whole group . Together with a satisfactory reduction of the excess overweight , laparoscopic gastric b and ing may lead in a carefully selected population of patients with morbid obesity to a significant improvment of patient QOL , in at least 2 years follow-up
Only outcomes of the IWQoL , SF-36 and OWQoL show QoL outcomes that exceed community norms .
The QoL is increased after bariatric surgery on both the short and long term .
However , due to the heterogeneity of the studies and the generality of the question naires is it hard to make a distinction between different surgeries and difficult to see a relation with medical profit .
Currently the effects of bariatric surgery are generally expressed in excess weight loss or comorbidity reduction .
Therefore the aim of this review was to provide insight in the available prospect i ve evidence regarding the short and long-term effects of bariatric surgery on Quality of Life ( QoL ) and a comparison with community norms .
