Analysis of correlation between BMI and TWL% outcome following metabolic and bariatric surgery: a retrospective study using restricted cubic spline. BMC Surg 2024; 24:178. [PMID: 38849774 PMCID: PMC11157919 DOI: 10.1186/s12893-024-02455-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2023] [Accepted: 05/16/2024] [Indexed: 06/09/2024] Open
Abstract
OBJECTIVE This study aimed to examine the correlation between preoperative body mass index (BMI) and adequate percentage of total weight loss (TWL%) outcome and present evidence of tiered treatment for patients with obesity in different preoperative BMI. METHODS We included patients with complete follow-up data who underwent metabolic and bariatric surgery (BMS). We termed optimal clinical response as TWL% >20% at one year following MBS. To investigate dose-response association between preoperative BMI and optimal clinical response, preoperative BMI was analyzed in three ways: (1) as quartiles; (2) per 2.5 kg/m2 units (3) using RCS, with 3 knots as recommended. RESULTS A total of 291 patients with obesity were included in our study. The corresponding quartile odds ratios associated with optimal clinical response and adjusted for potential confounders were 1.00 (reference), 1.434 [95% confidence interval (95%CI) = 0.589-3.495], 4.926 (95%CI = 1.538-15.772), and 2.084 (95%CI = 0.941-1.005), respectively. RCS analysis showed a non-linear inverted U-shaped association between preoperative BMI and optimal clinical response (Nonlinear P = 0.009). In spline analysis, when preoperative BMI was no less than 42.9 kg/m2, the possibility of optimal clinical response raised as preoperative BMI increased. When preoperative BMI was greater than 42.9 kg/m2, the possibility of optimal clinical response had a tendency to decline as preoperative BMI increased. CONCLUSION Our research indicated the non-linear inverted U-shaped correlation between preoperative BMI and adequate weight loss. Setting a preoperative BMI threshold of 42.9 is critical to predicting optimal clinical outcomes.

The Prognostic Value of the Dutch Sweet Eating Questionnaire on Weight Loss After Metabolic Surgery: a Randomized Controlled Trial. Obes Surg 2020; 30:2497-2504. [PMID: 32170552 DOI: 10.1007/s11695-020-04527-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 10/24/2022]
Abstract
BACKGROUND Laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG) have shown different weight loss results. These differences might be partly due to dumping after LRYGB, forcing sweet eaters to switch to a healthy diet. The Dutch Sweet Eating Questionnaire (DSEQ) is validated to measure sweet eating. This study aims to investigate if sweet eating measured with the DSEQ influences weight loss. METHODS In this multicenter randomized controlled trial, patients were included between 2013 and 2017 in two Dutch high-volume hospitals, and randomized with a 1:1 ratio between LRYGB and LSG. Primary outcome measure was weight loss. Secondary outcome measure was sweet eating behavior, measured with the DSEQ. Data was collected at baseline, 1 year and 2 years postoperatively. RESULTS Data was analyzed of 623 patients who underwent LRYGB (n = 308; 49.4%) or LSG (n = 315; 50.6%). Follow-up rates at 2 years postoperative were 67.1% for weight and 35.3% for DSEQ. At 2 years postoperative, mean BMI was significantly higher after LSG than LRYGB (respectively 30.88 versus 28.87 kg/m2, p < 0.001), and the percentage of sweet eaters was significantly higher after LSG than LRYGB (respectively 8.6% versus 2.6%, p = 0.049). None of the preoperative sweet eaters were sweet eaters 2 years after LRYGB (0.0%), versus 11.8% 2 years after LSG. No correlation was found between postoperative sweet eating behavior and %EBMIL. CONCLUSION No significant correlation was found between preoperative or postoperative sweet eating measured with the DSEQ and weight loss. The decision-making for the procedure type is more complex than weight loss and dietary habits, and should also involve quality of life and presence of comorbidities. These factors should be addressed in future research along with longer term results. TRIAL REGISTRATION Dutch Trial Register NTR-4741.

Abstract
OBJECTIVE There is a need to determine which bariatric operations are the most effective for patients with super obesity and super-super obesity. METHODS A retrospective cohort study was performed on patients with super obesity and super-super obesity at Mohak Bariatrics and Robotics Surgery Center in Indore, India. RESULTS Five hundred fourteen patients with super obesity and super-super obesity had surgery at our center from January 2010 through December 2013. The baseline characteristics were different in different operations. The initial average age, weight, and BMI were 44.4 (SD 11.9) years, 145.4 (SD 24.2) kg, and 55.48 (SD 5.32) kg/m2 , respectively. Sleeve gastrectomy (SG) (227 [44.2%]) was the most common procedure, followed by one-anastomosis gastric bypass (OAGB) (124 [24.1%]), Roux-en-Y gastric bypass (RYGB) (102 [19.8%]), banded sleeve gastrectomy (BSG) (33 [6.4%]), and banded Roux-en-Y gastric bypass (BRYGB) (28 [5.4%]). After 3 years, the percentages of excess body weight loss (%EBWL) for SG, OAGB, RYGB, BSG, and BRYGB were 62.38%, 78.59%, 69.55%, 85.11%, and 75.77% (P < 0.0001), respectively. Failure to achieve BMI < 35 kg/m2 was more frequent in the group who underwent SG (67.9%), followed by RYGB (29.16%), BRYGB (22.2%), OAGB (9.87%), and none in the BSG group. CONCLUSIONS BSG, OAGB, and BRYGB have very good to excellent midterm outcomes for patients with super obesity and super-super obesity, whereas RYGB and SG have average outcomes at 3 years. There is a need for multicenter, long-term, and prospective studies to be performed to confirm these findings.

Abstract
INTRODUCTION Laparoscopic adjustable gastric banding (LAGB) is proven to be a safe and effective treatment option for obesity in the long term. However, in recent decades, LAGB prevalence progressively decreased worldwide principally due to the incidence and the management of the complications. Understanding the optimal management of the complications becomes therefore of primary importance. The aim of this study is to describe a personal technical, laparoscopic solution of band erosion and to analyze outcomes in 47 patients. METHODS From October 1995 to January 2019, 3697 LAGB were performed at our institution. Since November 2011, an original laparoscopic gastric banding removal technique was introduced. All the bands placed in these patients were Lap-Band AP System (Allergan, Irvin, CA). The data of the patients who underwent gastric band removal because of band erosion were retrieved from a prospectively collected institutional database, and used for the present retrospective evaluation. RESULT Ninety-four patients (2.5% of the entire casuistic) with eroded band were diagnosed and treated at our institution. Forty-seven patients were treated with the laparoscopic gastric banding removal technique introduced in November 2011. All the operations have been performed laparoscopically with no conversion or intraoperative complications. There were neither major complications nor peri-operative (30 days) mortality. CONCLUSION Proper preoperative management and a standardized minimally invasive technique could help to cope with erosion, the most frightening complication of LAGB. Understanding the optimal management of complications and safe reoperation techniques can contribute to a rational use of the LAGB, reversing the current declining tendency.

A prospective study comparing 5-year results between superobese and non-superobese patients after laparoscopic adjustable gastric banding. Wideochir Inne Tech Maloinwazyjne 2019; 14:79-85. [PMID: 30766632 PMCID: PMC6372860 DOI: 10.5114/wiitm.2018.77269] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2018] [Accepted: 06/06/2018] [Indexed: 11/17/2022] Open
Abstract
Introduction Laparoscopic adjustable gastric banding (LAGB) is considered to be the least invasive, reversible, and the safest bariatric operation regarding mortality and morbidity, and its application to high-risk superobese (SO) individuals seems rational. Aim There are differing viewpoints regarding the effectiveness of LAGB in superobese (BMI > 50 kg/m2) patients. The aim of this study was to compare the safety and efficacy of LAGB in SO and non-superobese (NSO) patients in the long term (> 5 years). Material and methods We undertook a prospective single-center study to compare the safety and efficacy of LAGB in SO and NSO patients after 5 years. One hundred and three morbidly obese patients underwent LAGB in the period from January 2009 to January 2010. Sixty-four of the patients were NSO and 39 SO. After 5 years, we evaluated their weight loss, comorbidities, complications, and quality of life. Results A total of 90 of 103 patients (87.3%) completed the 5-year follow-up. The percentage excess weight loss was 50.4% in the NSO and 38.8% in the SO group (p = 0.072). The proportion of patients who lost > 50% excess weight was significantly larger in the NSO group (p = 0.045). There were significantly more patients in the NSO group whose metabolic syndrome had resolved (p < 0.001). There were no differences regarding the resolution of other comorbidities and postoperative complications. Conclusions This study suggests that LAGB can lead to substantial and long-lasting weight loss after 5 years. Our study found that SO patients demonstrate inferior weight loss results, and lower overall BAROS scores; thus we do not support the primary use of LAGB in SO patients.

Abstract
BACKGROUND A primary measure of the success of a procedure is the whether or not additional surgery may be necessary. Multi-institutional studies regarding the need for reoperation after bariatric surgery are scarce. OBJECTIVES The purpose of this study is to evaluate the rate of revisions/conversions (RC) after 3 common bariatric procedures over 10 years in the state of New York. SETTING University Hospital, involving a large database in New York State. METHODS The Statewide Planning and Research Cooperative System database was used to identify all patients undergoing laparoscopic adjustable gastric banding (LAGB), sleeve gastrectomy (SG), and Roux-en-Y gastric bypass (RYGB) between 2004 and 2010. Patients were followed for RC to other bariatric procedures for at least 4 years (up to 2014). Multivariable cox proportional hazard regression analysis was performed to identify risk factors for additional surgery after each common bariatric procedure. Multivariable logistic regression was used to check the factors associated with having ≥2 follow-up procedures. RESULTS There were 40,994 bariatric procedures with 16,444 LAGB, 22,769 RYGB, and 1781 SG. Rate of RC was 26.0% for LAGB, 9.8% for SG, and 4.9% for RYGB. Multiple RC ( = />2) were more common for LAGB (5.7% for LAGB, .5% for RYGB, and .2% for LSG). Band revision/replacements required further procedures compared with patients who underwent conversion to RYGB/SG (939 compared with 48 procedures). Majority of RC were not performed at initial institution (68.2% of LAGB patients, 75.9% for RYGB, 63.7% of SG). Risk factors for multiple procedures included surgery type, as LAGB was more likely to have multiple RC. CONCLUSIONS Reoperation was common for LAGB, but less common for RYGB (4.9%) and SG (9.8%). RC rate are almost twice after SG than after RYGB. LAGB had the highest rate (5.7%) of multiple reoperations. Conversion was the procedure of choice after a failed LAGB.

Abstract
PURPOSE Aim is to report the learning curve and standardization process of Laparoscopic Sleeve Gastrectomy (LSG), describing the evolution in surgical technique and patient management in the authors' experiences. METHODS One hundred twenty-seven patients were divided in three Groups (A, B, and C), based on bougie size and technical details, and included 36, 46, and 45 patients, respectively. RESULTS Mean operative time in Groups A, B, and C was 201.5, 150.8, and 172 minutes, respectively. Conversion to open surgery occurred in 1 Group A case. Eleven postoperative complications (8.6%) were observed (1 Group A, 8 Group B, 2 and Group C). Mean hospital stay in Groups A, B, and C, was 7.1, 6.9, and 3.1 days, respectively. At a mean follow-up of 69.7 months (Group A), 33.3 months (Group B), and 14.8 months (Group C), mean postoperative body mass index is 32.6, 28.1, and 31.5 kg/m2, respectively. Percentage estimated body mass index loss (%EBMIL) was 74.8% for Group A, 85.7% for Group B, and 68.1% for Group C. CONCLUSIONS LSG is a safe and effective procedure. In the postoperative course, meticulous alertness to early warning signs of sepsis and aggressive patient management are mandatory to prevent mortality. The use of a larger bougie size was associated with weight regain.

Abstract
BACKGROUND It is commonly believed that eating habits, specially the sweet eating habit, can predict results after bariatric surgery; for this reason, it is considered one of the selection criteria when deciding the surgical technique. However, there is not enough evidence of its impact on the results after sleeve gastrectomy (SG). OBJECTIVE To evaluate the relationship between the sweet eating habit and weight loss after SG. DESIGN Cross-sectional retrospective study. MATERIAL AND METHODS Group A: nonobese subjects, and group B: patients who underwent SG and had ≥6 months follow-up. Demographics, anthropometrics, percentage excess weight loss (%EWL) at 6, 12, and 24 months, and eating habits before surgery were analyzed. Sweet eating consumption was classified as follows: mild, moderate, and severe. Uni- and bivariate logistic regression analysis according to each variable was performed. RESULTS Between 2006 and 2011, 157 patients underwent SG at our institution; 36% were male, age 41 years old, and initial body mass index 46 kg/m(2). Mean %EWL at 6, 12, and 24 months was 66%, 77%, and 70%, respectively. Sweet eating consumption: Mild: 59%; Moderate: 38%; and Severe: 3%. No difference was found in sweet eating patterns among groups A and B; %EWL for mild, moderate, and severe sweet eaters at 6 months was 66 ± 16, 66 ± 14, and 65 ± 10, respectively (P = non-significant [NS]). The same analysis was made at 12 months: 76 ± 20, 79 ± 18, and 78 ± 11 (P = NS). At 24 months, only mild and moderate sweet eaters were available for comparison: 69 ± 23 and 73 ± 19, respectively (P = NS). CONCLUSION Preliminary data suggested that preoperative sweet eating habit would not predict results after SG in terms of weight loss.

Abstract
BACKGROUND Gastroesophageal reflux disease (GERD) and hiatal hernia (HH) are classically considered contraindications to bariatric restrictive procedures. Despite the high number of studies that have been published, the relationship between laparoscopic adjustable gastric banding (LAGB) and GERD/HH is still not clear. METHODS We have retrospectively analyzed the outcomes of LAGB in patients operated in 2010 with HH and/or GERD. The gastroesophageal reflux was diagnosed if the patients had heartburn and regurgitation more than once a week, and hiatal hernia was assessed by esophagogastroduodenoscopy and/or upper GI radiogram with swallow. Data on heartburn, assumption of antacid medication, weight loss, and rate of complications in both patients with and without GERD or HH were collected. RESULTS One hundred and twenty patients that underwent LAGB at our department were enrolled in our study; 40 had symptoms of GERD and 25 had hiatal hernia preoperatively. There was no difference of percentage excess weight loss (%EWL) at 12 months (45.4 ± 20.4 vs 4.6 ± 19.5 kg/m(2)) and 36 months follow-up (49.4 ± 16.5 vs 48.6 ± 18.9 kg/m(2)) between asymptomatic patients and patients with HH or GERD symptoms. The number of patients with preoperative heartburn (40 to 10) and/or assumption of antacid drugs (38 to 7) significantly decreased after LAGB CONCLUSIONS: LAGB is an effective and safe surgical treatment for morbidly obesity in patients with GERD or HH, since it induces both a significant weight loss and an improvement of reflux symptoms.

Abstract
OBJECTIVE The objective of the study is to identify the efficacy and safety of combining laparoscopic adjustable gastric banding with repair of large para-oesophageal hernias. BACKGROUND Para-oesophageal hernias are more common in the obese with higher recurrence rates following repair. The effect and safety of combining para-oesophageal hernia repair with laparoscopic adjustable gastric banding is unknown. METHODS One-hundred fourteen consecutive patients undergoing primary laparoscopic adjustable gastric banding with concurrent repair of a large para-oesophageal hernia were prospectively identified and matched to a control group undergoing primary laparoscopic adjustable gastric banding only. Weight loss and complication data were retrieved from a prospectively maintained database, and a standardised bariatric outcome questionnaire was used to assess post-operative symptoms, satisfaction with surgery and satiety scores. RESULTS At a mean follow up of 4.9 ± 2.1 years, total weight loss was 16.4 ± 9.9% in the hernia repair group and 17.6 ± 12.6% in the control group (p = 0.949), with 17 vs. 11% loss to follow up rates (p = 0.246). No statistically significant difference in revisional surgery rate and symptomatic recurrence of hiatal hernia was documented in four patients in the hernia repair group (3.5%). No statistically significant difference in mean reflux (9.9 vs. 10.3, p = 0.821), dysphagia (20.7 vs. 20.1, p = 0.630) or satiety scores was identified. CONCLUSIONS Concurrent repair of large para-oesophageal hiatal hernia and laparoscopic adjustable gastric banding placement is safe and effective both in terms of symptom control and weight loss over the intermediate term. In obese patients with large hiatal hernias, consideration should be given to combining repair of the hernia with a bariatric procedure.

Abstract
INTRODUCTION We sought to determine the rate of revision and explant of the laparoscopic adjustable gastric banding (LAGB) over a ten-year period in the state of New York. METHODS Following IRB approval, the SPARCS administrative database was used to identify LAGB placement from 2004 to 2010. We tracked patients who underwent band placement with subsequent removal/revision, followed by conversion to either Roux-en-Y gastric bypass (RYBG) or sleeve gastrectomy (SG) between 2004 and 2013. McNemar test and Chi-square test were used to compare complications between primary procedure and subsequent revision and to compare complication rates and mortality rates, respectively. Log-rank test was used to assess patient characteristics and comorbidities. p < 0.05 was considered significant. RESULTS During a 7-year period, there were 19,221 records of LAGB placements and 6567 records of revisions or removal. We were able to follow up 3158 (16.43 %) who subsequently underwent a band removal or revision over the course of this period. An additional 3606 patients had no records in the state of New York following the procedure, thus making the rate of revision 20.22 %. Initial revision procedures were coded as band removal in 32.77 % (n = 1035), band revision in 30.53 % (n = 964), band removal and replacement in 19.09 % (n = 603), removal and conversion to SG in 5.64 % (n = 178), or removal and conversion to RYGB in 11.97 % (n = 378). From the 3158 patients, 2515 (79.64 %) required only one revision. Six hundred and forty-three patients underwent two or more revisions. Thirty-one out of 3158 (0.0098 %) patients had complications at their initial operation, but 919 (29.1 %) had complications during revision (p < 0.0001). CONCLUSIONS Over a 7-year period, at least 20.22 % of LAGB required removal or revision. Based on all case numbers, total revision rate may be as high as 34.2 %. Although the band is believed to be a reversible procedure, revisional procedures are significantly more morbid than the initial procedure.

Abstract
BACKGROUND This study aimed to test the hypothesis that the amount of weight lost on a mandatory 2-week pre-operative very-low-calorie diet (VLCD) would predict the longer-term outcomes of laparoscopic adjustable gastric banding (LAGB). METHODS All patients treated with a primary LAGB from 21 October 2008 until 30 June 2010, who were prescribed a 2-week pre-operative VLCD, have been included in the study. Patient age, weight, BMI and excess weight (defined as weight above a BMI of 25) were extracted on the day of first visit, day of surgery and at the post-operative visits at 3, 12 and 24 months. From these data, percent excess weight loss (EWL) was calculated and compared at all time points. RESULTS The weight loss achieved on a mandatory 2-week pre-operative diet did not predict weight outcomes at 2 years (r = -0.008; p = 0.931). Using multivariate analysis, the best predictor of 24-month percent EWL was percent EWL at 3 months post operation (sr(2) = 0.34; p = 0.003). CONCLUSIONS Results from a pre-operative diet should not be used to predict the ultimate outcome of bariatric surgery. The weight loss at 3 months following LAGB was a strong predictor of longer-term outcomes. There may be potential for improving longer-term results with LAGB by better supporting patients who are not achieving good weight loss at this early time point.

Abstract
The study objective was to ascertain outcomes with the Swedish adjustable gastric band (SAGB) on an intention-to-treat basis in multiple centers across the French social health insurance system. SAGB results at 3-year follow-up are reported. The noncomparative, observational, prospective, consecutive cohort study design sought a 500-patient minimum recruitment geographically representative of continental France. Safety (adverse events [AEs], device-related morbidity, and mortality) and effectiveness (change in body mass index [BMI, kilograms per square meter], percentage excess weight loss, comorbidities, quality of life [QoL]) were assessed. Adjustable gastric band survival was calculated. Thirty-one surgeons in 28 multidisciplinary teams/sites enrolled patients between September 2, 2007 and April 30, 2008. SAGB was successfully implanted in 517 patients: 88.0 % female; mean age, 37.5 years; obesity duration, 15.3 years (baseline: mean BMI, 41.0; comorbidities, 773 in 74.3 % of patients; Bariatric Analysis and Reporting Outcome System (BAROS), 1.4; EuroQoL 5-Dimensions (EQ-5D), 0.61; EuroQoL-visual analog scale (EQ-VAS), 52.3). At 3 years: BMI, 32.2 (mean change, -9.0; p < 0.0001); excess weight loss, 47.4 %; comorbidities, 161 in 27.2 %; BAROS, 3.6 (+2.2, p < 0.0001); EQ-5D, 0.84 (+0.22, p < 0.0001); EQ-VAS, 73.4 (+21.4, p < 0.0001). SAGB-induced weight loss was associated with substantially improved QoL. One death occurred and was unrelated to the treatment. No AE was reported in 68.3 % of patients, and no confirmed device-related AE in 77.0 %. Overall AE rate was 0.19 per patient year. Device retention was 87.0 %. Analysis of patients lost to follow-up showed a nonsignificant effect on overall study results. In a prospective, consecutive cohort, "real-world", nationwide study, the Swedish Adjustable Gastric Band was found safe and effective at 3-year follow-up.

Abstract
BACKGROUND Obesity affects 32% of adults in the USA. Surgery generates substantial weight loss, but 20-30% fails to achieve successful weight loss. Our objective was to identify preoperative psychosocial factors associated with weight loss following bariatric surgery. METHODS We performed a literature search of PubMed® and the Cochrane Database of Reviews of Effectiveness between 1988 and April 2010. Articles were screened for bariatric surgery and weight loss if they included a preoperative predictor of weight loss: body mass index (BMI), preoperative weight loss, eating disorders, or psychiatric disorder/substance abuse. One thousand seven titles were reviewed, 534 articles screened, and 115 included in the review. RESULTS Factors that may be positively associated with weight loss after surgery include mandatory preoperative weight loss (7 of 14 studies with positive association). Factors that may be negatively associated with weight loss include preoperative BMI (37 out of 62 studies with negative association), super-obesity (24 out of 33 studies), and personality disorders (7 out of 14 studies). Meta-analysis revealed a decrease of 10.1% excess weight loss (EWL) for super-obese patients (95% confidence interval (CI) [3.7-16.5%]), though there was significant heterogeneity in the meta-analysis, and an increase of 5.9% EWL for patients with binge eating at 12 months after surgery (95% CI [1.9-9.8%]). CONCLUSIONS Further studies are necessary to investigate whether preoperative factors can predict a clinically meaningful difference in weight loss after bariatric surgery. The identification of predictive factors may improve patient selection and help develop interventions targeting specific needs of patients.

Abstract
BACKGROUND There are conflicting results concerning the bariatric effectiveness of adjustable gastric banding in super-obese patients with a Body Mass Index (BMI) more or equal to 50 kg/m(2). METHOD A cohort of 186 patients with a BMI greater or equal to 50 kg/m(2) who underwent adjustable gastric banding (AGB) at the Bichat-Claude-Bernard University Hospital (Paris, France) were prospectively entered into a database. The following data were recorded: BMI, percentage of BMI loss, percentage of excess weight lost (%EWL), complications, and surgical re-interventions. Loss of greater than 50% of excess weight was considered a success (primary endpoint). A %EWL of less than 25% after one year, or the removal of the gastric band was considered a failure. RESULTS Thirty-five men (18.8%) and 151 women (81.2%), with a mean age of 38.9 years (range: 16-65) underwent AGB between September 1995 and December 2007. The mean BMI was 55.06 kg/m(2) (range: 50-74.4). Mean follow-up was 112.5 months with a minimum of 28 months and a maximum of 172 months. The follow-up rate was maintained at 89% at ten years. The technique of AGB was by "peri-gastric dissection" in the first 115 patients (61.82%) and by "pars flaccida dissection" in 71 patients (38.17%). The gastric band was removed in 87 of 186 patients (46.8%); band ablation was due to a complication of the gastric band in 62 of these cases (33.3%), to failure of weight loss in 23 cases (12.4%), and to patient request in two cases (1%). The major complications requiring re-operation were: chronic dilatation of the proximal gastric pouch (27 patients - 14.5%), acute dilatation (21 patients - 11.3%), intragastric migration of the prosthesis (six patients - 3.2%), reflux esophagitis (six patients - 3.2%), infection of the gastric band (one patient - 0.5%), and Barrett's esophagus (one patient - 0.5%). No statistically significant difference was found between the two operative techniques with regard to the possibility of preserving the gastric band for ten years. For patients who underwent band removal, no further follow-up analysis of patient data after band ablation was performed. The results were best at two years after AGB with a median BMI of 42.72 kg/m(2), a band removal rate of 8.6% (16 of 186 patients), and a failure rate of 16.4% (28 of 170 patients) of those patients who still had their band in place. However, at 10 years, the picture was completely reversed with a band removal rate of 52.2% (47 of 90 patients), a failure rate of 22% (seven of 33 patients) of those who still had their band in place, and a median BMI of 43.43 kg/m(2). CONCLUSION Laparoscopic gastroplasty using the adjustable gastric band appeared to be a promising intervention for super-obese patients when the results at two years were analyzed - fairly simple to perform, with perioperative morbidity and mortality near zero. However, these results do not persist in the long-term for super-obese patients. At ten years, only 11% of patients (nine of 80) have successful bariatric results (%EWL>50%) and we were forced to remove the gastric band in 52.2% of patients (47 of 90) because of complications, regardless of the initial operative technique used. Given these results, AGB gastroplasty is not a recommended method for super-obese patients and we believe that a BMI greater or equal to 50 kg/m(2) is a contra-indication for this procedure.

Abstract
BACKGROUND Substantial weight loss is achieved in majority of severely obese subjects undergoing laparoscopic gastric bypass (LGBP) but some fail to obtain expected results. Our aim was to identify preoperative factors that could influence weight loss (WL) 1 year after LGBP. METHODS We studied the predictive value of clinical, biological, and dietary preoperative factors on weight loss in obese patients referred for LGBP. WL was assessed according to mean absolute weight loss (AWL) and mean percent excess weight loss (%EWL) 1 year after LGBP. RESULTS One hundred twenty-three subjects were included (112 women, age 42 ± 10 years; weight 127 ± 23 kg; BMI 47 ± 8 kg/m(2)). Mean AWL was 39.4 ± 10.5 kg at 1 year, corresponding to a mean %EWL of 70.5 ± 21.2%. AWL was positively correlated with initial weight, BMI, and energy intake and negatively with age, female sex, and treatment for hypertension and diabetes. %EWL was negatively correlated with initial weight, BMI, and positively correlated with triglycerides and ferritinemia. In multivariate analysis, %EWL was negatively correlated only with initial BMI (p < 0.001). AWL was positively correlated with initial BMI and male sex (both p < 0.001), and negatively correlated with protein intake (p = 0.039) and treatment for diabetes (p = 0.021), but not with biomarkers of diabetes and insulin resistance. CONCLUSION Initial BMI appears to be a strong determinant of individual WL, but predictive factors differ when WL was expressed as %EWL or AWL. The treatment of diabetes rather than diabetes itself appears to affect WL.

Abstract
OBJECTIVE To analyze the cost-effectiveness of bariatric surgery in severely obese (BMI >or=35 kg/m(2)) adults who have diabetes, using a validated diabetes cost-effectiveness model. RESEARCH DESIGN AND METHODS We expanded the Centers for Disease Control and Prevention-RTI Diabetes Cost-Effectiveness Model to incorporate bariatric surgery. In this simulation model, bariatric surgery may lead to diabetes remission and reductions in other risk factors, which then lead to fewer diabetes complications and increased quality of life (QoL). Surgery is also associated with perioperative mortality and subsequent complications, and patients in remission may relapse to diabetes. We separately estimate the costs, quality-adjusted life-years (QALYs), and cost-effectiveness of gastric bypass surgery relative to usual diabetes care and of gastric banding surgery relative to usual diabetes care. We examine the cost-effectiveness of each type of surgery for severely obese individuals who are newly diagnosed with diabetes and for severely obese individuals with established diabetes. RESULTS In all analyses, bariatric surgery increased QALYs and increased costs. Bypass surgery had cost-effectiveness ratios of $7,000/QALY and $12,000/QALY for severely obese patients with newly diagnosed and established diabetes, respectively. Banding surgery had cost-effectiveness ratios of $11,000/QALY and $13,000/QALY for the respective groups. In sensitivity analyses, the cost-effectiveness ratios were most affected by assumptions about the direct gain in QoL from BMI loss following surgery. CONCLUSIONS Our analysis indicates that gastric bypass and gastric banding are cost-effective methods of reducing mortality and diabetes complications in severely obese adults with diabetes.

Abstract
BACKGROUND Approximately one-third of U.S. adults are obese. Current evidence suggests that surgical therapies offer the morbidly obese the best hope for substantial and sustainable weight loss, with a resultant reduction in morbidity and mortality. Minimally invasive methods have altered the demand for bariatric procedures. However, no evidence-based clinical reviews yet exist to guide patients and surgeons in selecting the bariatric operation most applicable to a given situation. METHODS This evidenced-based review is presented in conjunction with a clinical practice guideline developed by the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES). References were reviewed by the authors and graded as to the level of evidence. Recommendations were developed and qualified by the level of supporting evidence available at the time of the associated SAGES guideline publication. The guideline also was reviewed and co-endorsed by the American Society for Metabolic and Bariatric Surgery. RESULTS Bariatric surgery is the most effective treatment for severe obesity, producing durable weight loss, improvement of comorbid conditions, and longer life. Patient selection algorithms should favor individual risk-benefit considerations over traditional anthropometric and demographic limits. Bariatric care should be delivered within credentialed multidisciplinary systems. Roux-en-Y gastric bypass (RGB), adjustable gastric banding (AGB), and biliopancreatic diversion with duodenal switch (BPD + DS) are validated procedures that may be performed laparoscopically. Laparoscopic sleeve gastrectomy (LSG) also is a promising procedure. Comparative data find that procedures with more dramatic clinical benefits carry greater risks, and those offering greater safety and flexibility are associated with less reliable efficacy. CONCLUSIONS Laparoscopic RGB, AGB, BPD + DS, and primary LSG have been proved effective. Currently, the choice of operation should be driven by patient and surgeon preferences, as well as by considerations regarding the relative importance placed on discrete outcomes.

Abstract
Choosing the right operation for weight loss continues to be a challenging and subjective process. In experienced hands, most operations have the ability to be successful in providing a given patient with meaningful weight loss and impart better health through loss of adiposity, amelioration of comorbidities, and improvement of overall quality of life.

Abstract
CONTEXT GH secretion is reduced in obese subjects and increases after body weight loss. It is still unclear if changes in the GH/IGF-I axis after laparoscopic-adjustable silicone gastric banding (LASGB) are associated with changes of body composition. OBJECTIVE To analyse the relationships between changes in the GH/IGF-I axis and those of body weight and composition before and after LASGB. DESIGN Observational, prospective. SETTING University 'Federico II' of Naples (Italy). PATIENTS Seventy-two severely obese females (BMI: 44.9 +/- 4.68; mean age: 33.1 +/- 11.34 years) were studied. MAIN OUTCOME MEASURES GH peak after GHRH plus arginine test, IGF-I, IGFBP-3 and ALS levels, fat mass (FM) and free fat mass (FFM) (by Bioelectrical Impedance Analysis) at baseline and 6 months after LASGB. The change in percentage of individual variables was calculated as well as that of excess of body weight loss (EBWL%). The FM%, FFM% and EBWL% were correlated with peak GH and IGF-I levels changes. RESULTS At baseline, GH deficiency (GHD) (GH peak = 4.1 microg/l) was found in 22 patients (31%), 16 of them also had IGF-I deficiency (< -2SDS). IGF-I levels were inversely correlated with waist circumference (r = -0.72, P < 0.001) and FM% (r = -0.75, P < 0.001). Post-LASGB the patients were classified as follows: group (1) GH and IGF-I sufficient (n = 44; 61.1%); group (2) GH and IGF-I deficient (n = 14; 19.4%) and group (3) GH sufficient and IGF-I deficient (n = 14; 19.4%). The percentage changes of EWBL (P < 0.05, P = 0.051, respectively) and FM (P < 0.001, P < 0.01, respectively) were lower in groups (2) and (3) than in group (1). At the stepwise linear regression analysis, postoperative IGF-I levels were the strongest determinant of percent changes of FM (P < 0.0001), of FFM (P = 0.009) and of EBWL (P < 0.0001). CONCLUSIONS IGF-I levels is the most sensitive to unfavourable changes in body composition 6 months after LASGB making investigation of the somatotropic axis useful in the evaluation of bariatric surgery outcomes.

[PMID: 18243060 DOI: 10.1016/j.soard.2007.10.013] [Citation(s) in RCA: 51] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2007] [Revised: 09/09/2007] [Accepted: 10/19/2007] [Indexed: 11/21/2022]
Abstract
BACKGROUND We previously reported significantly longer operating room times and a trend toward increased complications and mortality in the super-super obese (body mass index [BMI] > or =60 kg/m(2)) early in our experience with laparoscopic Roux-en-Y gastric bypass. The goal of this study was to re-examine the short-term outcomes for super-super obese patients undergoing weight loss surgery at our high-volume bariatric surgery center well beyond our learning curve. METHODS The records for all patients who had undergone weight loss surgery at Hackensack University Medical Center from 2002 to June 2006 were harvested from the hospital's electronic medical database. This population was analyzed as 2 groups (those with a BMI <60 kg/m(2) and those with a BMI > or =60 kg/m(2)), as well as by type of operation. Step-wise and univariate logistic regression analyses assessed the effect of BMI on the outcome variables, including mortality, length of surgery, length of hospital stay, and disposition at discharge. RESULTS A total of 3692 patients were studied. Of these patients, 3401 had a BMI <60 kg/m(2) and 291 had a BMI > or =60 kg/m(2). Of the 291 super-super obese patients, 130 underwent vertical banded gastroplasty-Roux-en-Y gastric bypass, 116 laparoscopic Roux-en-Y gastric bypass, and 45 laparoscopic adjustable gastric banding. The proportion of male patients, black patients, and patients with sleep apnea was increased in the BMI > or =60 kg/m(2) group. The number of co-morbid diseases per patient correlated with age but not BMI. The BMI > or =60 kg/m(2) group required a significantly longer total operating room time (136 versus 120 min). Hospital length of stay was significantly longer only in the laparoscopic Roux-en-Y gastric bypass patients (3 d for the BMI > or =60 kg/m(2) group versus 2 d for the BMI <60 kg/m(2) group). A significantly greater percentage of patients in the super-super obese group were discharged to chronic care facilities. The overall in-hospital mortality rate was 0.15% (5 of 3692) but did not significantly differ between the 2 groups: BMI <60 kg/m(2), rate of 0.12% (4 of 3401 patients), and BMI > or =60 kg/m(2), rate of 0.34% (1 of 291 patients). The type of operation did not significantly affect the disposition at discharge or in-hospital mortality. CONCLUSION Super-super obese patients required longer total operating room times, a longer hospital length of stay, and were more likely to be discharged to chronic care facilities than were patients with a BMI <60 kg/m(2); however, the in-hospital mortality was similar for both groups.

Abstract
The prevalence of obesity in the United States has reached epidemic proportions. With more than 30 million Americans clinically obese, the younger population has also been affected. Surgical therapy should be offered to the severely obese patient who is refractory to nonsurgical therapy, as established by the 1991 NIH Consensus Conference on Gastrointestinal Surgery for Severe Obesity. Surgery is currently the most effective therapy for weight loss. It is far more effective than any other treatment modality, both in terms of the amount of weight loss and in terms of durability in maintaining weight loss.

J Thorac Cardiovasc Surg 2006; 131:1130-5. [PMID: 16678600 DOI: 10.1016/j.jtcvs.2005.12.045] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/06/2005] [Revised: 11/18/2005] [Accepted: 12/01/2005] [Indexed: 10/24/2022]
Abstract
BACKGROUND Pulmonary artery banding is proposed as a first palliation in infants with complex congenital heart disease and high pulmonary blood flow. In addition, it may be used to retrain the left ventricle. Optimal tightening may be difficult to obtain, leading to reoperation. An implantable device for pulmonary artery banding with telemetric control was recently developed allowing for repeated adjustments, but it is presently limited to patients weighing less than 20 kg. In large animals, we tested an off-label adjustable gastric banding system for pulmonary artery banding. METHODS AND RESULTS Fourteen ewes weighing 50 to 75 kg underwent implantation of the Lap-Band device (BioEnterics Corp, Santa Barbara, Calif) around the main pulmonary artery through a left thoracotomy. All had functional evaluation with progressive occlusion and opening of the device at implantation and every 2 weeks until sacrifice immediately after implantation (group 1, n = 8), at 1 month (group 2, n = 3), at 3 months (group 3, n = 3), or death. Invasive pressure measurements in the right ventricle and aorta were carried out each time. Devices were easily implanted in all animals. Progressive occlusion and reopening were possible in all animals during each time point. Two animals died of right heart failure related to excessive tightening of the band. Retrieval of the device without any major damage was possible in 12 of 14 animals. CONCLUSION With this implantable device, we were able to adjust the pulmonary artery diameter in animals. Patients requiring left ventricle retraining and weighing more than 30 kg would benefit from the device's use in humans.

Abstract
The surgical treatment of obesity has existed for over 50 yr. Surgical options have evolved from high-risk procedures infrequently performed, to safe, effective procedures increasingly performed. The operations used today provide significant durable weight loss, resolution or marked improvement of obesity-related comorbidities, and enhanced quality of life for the majority of patients. The effect of bariatric surgery on the neurohormonal regulation of energy homeostasis is not fully understood. Despite its effectiveness, less than 1% of obese patients are treated surgically. The perception that obesity surgery is unsafe remains a deterrent to care.

Abstract
BACKGROUND The purpose of this study was to examine 1,014 consecutive laparoscopic adjustable gastric banding (LAGB) procedures with up to 48 months of followup, including evolution and changes in surgical technique, learning curve issues, weight loss outcomes, and complications. STUDY DESIGN Between October 2000 and December 2004, 1,014 consecutive patients (81.8% women, mean age 42.3 years, mean body mass index 47.7 +/- 8.6 kg/m(2)) underwent LAGB operation at our center. Perigastric dissection was used in the first 44 patients; pars flaccida technique was used for the latter 970 patients. Fluoroscopy-guided adjustments were performed and patients received intensive followup. RESULTS Excess weight loss at 12, 24, 36, and 48 months was 40.5 +/- 17%, 52.9 +/- 19.5%, 62 +/- 20.9%, and 64.3 +/- 19%, respectively, with data available in > 85% of patients who had reached each of the time intervals. Patients with lower preoperative body mass index had higher excess weight loss initially, but this difference was not apparent at 3 and 4 years' followup. At 36 and 48 months, respectively, 73.5% and 75% of patients had > 50% excess weight loss. Perigastric dissection led to 9 of 44 (20.5%) slippages, compared with 14 of 970 (1.4%) with pars flaccida technique. Other complications included 2 erosions (0.2%), 5 tubing breaks (0.5%), 7 access port problems (0.7%), and 14 acute stoma obstructions (1.4%). Eight (0.8%) bands were explanted. No deaths occurred. CONCLUSIONS LAGB can achieve effective and safe weight loss. Change from perigastric to pars flaccida technique reduced slippage rate. Preoperative body mass index alone was not found to be a predictor of effective weight loss in the longterm.

Abstract
Bariatric surgery is the only effective treatment producing sustained weight loss and reduction in comorbidities in the morbidly obese. Laparoscopic adjustable gastric banding (LAGB) has evolved considerably in techniques of insertion and band management since the initial descriptions in the early 1990s. Major advantages of LAGB include lower perioperative morbidity and mortality, adjust-ability, and reversibility. Although weight loss occurs more slowly than after gastric bypass, end results are comparable.
