[PMID: 33765292 DOI: 10.1007/s11695-021-05334-9] [Citation(s) in RCA: 28] [Impact Index Per Article: 9.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2020] [Revised: 02/27/2021] [Accepted: 03/04/2021] [Indexed: 12/26/2022]
Abstract
INTRODUCTION Laparoscopic sleeve gastrectomy (LSG) is the most popular bariatric procedure performed worldwide. However, many patients undergo secondary surgery due to either weight-related and complication-related reasons or both. Conversional options vary with one-anastomosis gastric bypass (OAGB) and Roux-n-Y gastric bypass (RYGB) being the most common. The aim of the study was to assess the safety and efficacy of converting failed LSG to either OAGB or RYGB, and compare weight-related results and post-conversion complications. METHODS Retrospective review of hospital records of patients who underwent conversion from LSG to either RYGB or OAGB due to insufficient weight loss or weight regain in 7 bariatric centers between 2013 and 2019. Data retrieved included demographics, anthropometrics, comorbidities, indication for conversion, conversion type, complications, and weight loss. RESULTS During the study period, 396 patients were included in the study. Eighty-four (21%) patients were lost to follow-up. RYGB and OAGB were performed in 119 and 144 patients, respectively. Mean age and body mass index (BMI) at revision were 44.2 years (range 19-72) and 40.6 ± 5.9 kg/m2 (range 35-71), respectively. Of these, 191 (73%) were female. Percent total body weight loss (%TWL) was 16% ± 1% for the RYGB group vs. 23% ± 12% for the OAGB group (p = 0.0007) at a median follow-up of 29 months (range 7-78 months) following conversion. Gastroesophageal reflux disease (GERD) was significantly higher 1 year following conversion to OAGB vs. RYGB occurring in 25 (17.4%) and 9 (7.6%) patients, respectively (p = 0.018). CONCLUSIONS Conversion of LSG to OAGB, compared to RYGB, results in increased weight loss but a higher rate of GERD and potential nutritional deficiencies.

A 9 years comparison of weight loss, disappearance of obesity, and resolution of diabetes mellitus with biliointestinal bypass and with adjustable gastric banding: experience of a collaborative network. Acta Diabetol 2019; 56:163-169.

Abstract
AIMS Long-term comparisons between bariatric surgical techniques have been performed for gastric bypass (RYGB), sleeve gastrectomy (LSG), and biliopancreatic diversion (BPD) vs gastric banding (LAGB), but short-term studies (6 months-4 years) have only compared biliointestinal bypass (BIBP) and LAGB. The participating institutions regularly perform both BIBP and LAGB with a common protocol, and the aim of this retrospective study was to compare long-term effects of the two procedures on body weight, on clinical and metabolic variables, and on resolution of obesity and of diabetes. METHODS All procedures performed between 01/01/1998 and 31/12/2005 were considered; 73 out of 91 patients undergoing BIBP, and 154 out of 249 patients undergoing LAGB were evaluable up to 9 years. RESULTS BIBP was significantly more effective than LAGB in terms of weight loss and of resolution of obesity (BMI < 30 kg/m2), in terms of decrease of systolic blood pressure and of serum cholesterol, and similar in terms of resolution of diabetes. In addition, the effect of BIBP was stable, while the effect of LAGB decreased with time. CONCLUSIONS Both BIBP and LAGB exert long-term effects on body weight, on blood pressure, and on resolution of diabetes mellitus; the effect of BIBP is significantly greater than the effect of LAGB in terms of weight loss, resolution of obesity, of control of systolic blood pressure and of serum cholesterol, but not in terms of resolution of diabetes.

Abstract
BACKGROUND There is overwhelming evidence for the antidiabetic effect of obesity surgery, but few reports involve objective longitudinal measurements of severity of type-2 diabetes mellitus (T2DM). This study applies a grading scheme and analyses the prognostic impact of routine clinical factors. MATERIAL AND METHODS This retrospective study includes 77 obese diabetic patients with a preoperative BMI of 48.9 ± 7.8 kg/m(2) who underwent gastric banding (n = 4), Roux-en-Y gastric bypass (n = 57), or sleeve gastrectomy (n = 16) between 2007 and 2013. A 6-point scoring system graded the level of antidiabetic therapy. Downgrading was calculated from the difference between pre- and postoperative grades. RESULTS Downgrading reached its maximum at 3 months well before maximal weight loss: one grade in 6 (8 %) patients, two grades in 36 (47 %) patients, and three or more grades in 20 (26 %) patients. Age, gender, and preoperative weight had no impact on downgrading. There were no significant differences between gastric banding (median 1; 0-2), gastric bypass (median 2; 0-5), and sleeve gastrectomy (median 2; 0-4). Preoperative duration of T2DM and its severity grade were independent prognostic factors in multivariate analysis. The rate of patients who could discontinue insulin was more than 80 % when the duration of preexisting T2DM was less than 5 years as compared to 62 % when the duration was more than 5 years. CONCLUSION The severity of T2DM downgrades in most patients within the initial period of postoperative weight loss. Downgrading increases with shorter duration and lower severity grade of pre-existing T2DM.

Abstract
BACKGROUND Obesity, metabolic syndrome (MS) and dyslipidemia are independent risk factors for cardiovascular disease. Bariatric surgery is increasingly recognized as an effective intervention for improving each of these risk factors. There are sparse data on the long-term durability of metabolic changes associated with bariatric surgery, in particular with laparoscopic gastric banding (LGB). Our objective was to evaluate the durability of metabolic changes associated with LGB in nonmorbid obesity. METHODS Fifty obese patients (BMI 30-40) with ≥1 obesity-related comorbidity were prospectively followed for five years. At follow-up, subjects underwent fasting blood measures, including lipid NMR spectroscopy and standard lipid profile. RESULTS Forty-seven patients (45 female, mean age 43.8 years) completed four years follow-up (46 completed five years). Baseline BMI was 35.1 ± 2.6. Subjects exhibited mean weight loss of 22.3 ± 7.9 kg (22.9 ± 7.4%) at year one and maintained this (19.8 ± 10.2%) over five years. At baseline, 43% (20/47) of subjects met criteria for MS. This was reduced to 15% (7/47) at year one and remained reduced over five years (13%, 6/46) (p < 0.001). There were reductions in triglycerides (p < 0.001) and increases in HDL cholesterol (HDL-C, p < 0.001) and HDL particle concentration (p = 0.02), with a trend toward increased HDL particle size (p = 0.06) at year five. Changes in triglycerides and HDL-C were more prominent in patients with MS at baseline, but unassociated with weight loss or waist circumference. Changes in HDL particle size and concentration were not associated with MS status, weight loss, waist circumference, or statin use. CONCLUSIONS LGB produces significant weight loss, resolution of MS and changes in lipid profile suggestive of beneficial HDL remodeling. These changes persist five years following LGB.

Abstract
Long-term weight loss after Roux-en-Y gastric bypass (RYGB) in super-obese patients has not been ideal. Biliopancreatic diversion with duodenal switch (DS) is argued to be better; however, additional side effects are feared. The aim of the present study was to determine differences in results after DS and RYGB in publications from single-centre comparisons. A systematic review of studies containing DS and RYGB performed at the same centre was performed. Outcome data were weight results, resolution of comorbid conditions, perioperative results and complications. Main outcome was difference in weight loss after DS and RYGB. Secondary outcomes were difference in resolution of comorbidities, perioperative results and complications. The final analysis included 16 studies with in total 874 DS and 1,149 RYGB operations. When comparing weight results at the longest follow-up of each study, DS yielded 6.2 (95% confidence interval 5.0-7.5) body mass index units additional weight loss compared with RYGB, P < 0.001. Operative time and length of stay were significantly longer after DS, as well as the risk for post-operative leaks, P < 0.05. DS is more effective than RYGB as a weight-reducing procedure. However, this comes at the price of more early complications and might also yield slightly higher perioperative mortality.

Abstract
Massive obesity results in serious diseases, which are a major public health problem. Surgery is frequently the only means to achieve and sustain significant weight loss. This historical overview is aimed at providing knowledge and appreciation of this surgery to scientists in other complex areas of nutrition. The development of these operations is provided, including their potential nutritional sequelae. Because type 2 diabetes frequently improves or resolves postoperatively, related operations are being investigated in patients with lower weights.

Abstract
PURPOSE To determine the effects of laparoscopic adjustable gastric banding (LAGB) on albuminuria in patients with obesity, type 2 diabetes mellitus (T2DM) and established diabetic nephropathy. METHODS A retrospective analysis of clinical records from a tertiary diabetes service identified obese patients with T2DM who had micro- or macroalbuminuria prior to LAGB surgery. Clinical data from follow-up appointments including albuminuria were analysed. RESULTS A total of 23 T2DM patients were included in the final study. Of 7 patients with macroalbuminuria at baseline, 2 reverted to normoalbuminuria, 2 reverted to microalbuminuria and 3 remained with macroalbuminuria on their final recording in the 36-month period of follow-up. Of 16 patients with microalbuminuria, 9 reverted to normoalbuminuria, while 6 remained with microalbuminuria. CONCLUSION This study demonstrates significant improvements in albuminuria in patients with established diabetic nephropathy following LAGB. These results suggest the potential for LAGB to improve or reverse renal damage in patients with T2DM.

Abstract
OBJECTIVE It has been postulated that the effectiveness of bariatric surgery varies between ethnic groups. However, data regarding this topic are inconclusive, as most studies included few patients from minority groups. We conducted a meta-analysis to determine the difference in percentage of excess weight loss (%EWL) 1-2 years after bariatric surgery in people of African and Caucasian descent. We also studied differences in diabetes mellitus (DM) remission. RESEARCH DESIGN AND METHODS We performed a MEDLINE and EMBASE search for studies reporting %EWL and/or DM remission after bariatric surgery and including both African Americans and Caucasians. The 613 publications obtained were reviewed. We included 14 studies (1,087 African Americans and 2,714 Caucasians); all provided data on %EWL and 3 on DM remission. We extracted surgery type, %EWL, and DM remission 1-2 years after surgery. After analyzing %EWL for any surgery type, we performed subanalyses for malabsorptive and restrictive surgery. RESULTS The overall absolute mean %EWL difference between African Americans and Caucasians was -8.36% (95% CI -10.79 to -5.93) significantly in favor of Caucasians. Results were similar for malabsorptive (-8.39% [-11.38 to -5.40]) and restrictive (-8.46% [-12.95 to -3.97]) surgery. The remission of DM was somewhat more frequent in African American patients than in Caucasian patients (1.41 [0.56-3.52]). However, this was not statistically significant. CONCLUSIONS In %EWL terms, bariatric surgery is more effective in Caucasians than in African Americans, regardless of procedure type. Further studies are needed to investigate the exact mechanisms behind these disparities and to determine whether ethnic differences exist in the remission of comorbidities after bariatric surgery.

Abstract
BACKGROUND Bariatric surgery has been proposed as the most effective treatment for patients with type 2 diabetes mellitus (T2DM) and body mass index (BMI) above 35 kg/m(2). The purpose of our study was to access remission rate and improvement of metabolic control of T2DM after gastric bypass. METHODS A prospective study was carried out on 94 diabetic patients, who underwent gastric bypass with a 200-cm biliopancreatic limb. Characteristics evaluated included weight, BMI, percentage of excess BMI lost (% EBMIL), fasting glucose, HbA1c, and lipid profile up to 36 months after surgery, as well as anti-diabetic treatment before and after surgery. RESULTS At the time of surgery, patients had a mean BMI of 44.3 ± 0.65 kg/m(2) and length of T2DM diagnosis of 6.2 ± 0.98 years and HbA1c of 6.6 ± 0.21%. After a mean time of follow-up of 2.6 ± 0.13 years, the weight loss was significant from 3 months onwards after surgery, reaching its peak at 24 months with a BMI of 32.1 ± 0.9 kg/m(2) and corresponding % EBMIL of 69.0 ± 2.84%. Remission rates of diabetes were 87.91% at 6 months, 92.68% at 12 months, 92.85% at 24 months, and 100% at 36 months of follow-up. CONCLUSIONS Gastric bypass in obese patients is associated with a high remission rate of diabetes and improvement of the metabolic control. Although confirmation with randomized controlled studies is needed, these results suggest that this type of surgery might be particularly indicated for obese diabetic patients with good pancreatic reserve.

Abstract
Obesity is a major worldwide problem in public health, reaching epidemic proportions in many countries, especially in urbanized regions. Bariatric procedures have been shown to be more effective in the management of morbid obesity, compared to medical treatments in terms of weight loss and its sustainability. The two most commonly performed procedures are laparoscopic Roux-en-Y gastric bypass (LRYGB), laparoscopic adjustable gastric banding (LAGB), and the novel laparoscopic sleeve gastrectomy (LSG). The MEDLINE database (cutoff date September 2010), LILACS, and the Cochrane Library were searched using the key words "gastric bypass," "sleeve gastrectomy," and "gastric banding." Only studies that compared at least two of the laparoscopic procedures were included. Reviews and meta-analysis, editorial letters or comments, case reports, animal or in vitro studies, comparisons with medical treatment, comparisons with open (non-laparoscopic) procedures were excluded. Most studies indicated that LRYGB and LSG could be more effective achieving weight loss than LAGB. However, LAGB seems to be a safer procedure with frequent, but less severe, long-term complications. Although not uniformly reported, a resolution of obesity-related comorbidities was achieved with most bariatric procedures. The three procedures have acceptable efficacy and safety. We believe that patients should be informed in detail on the advantages and disadvantages of each available procedure, possibly in several interviews and always accompanied by a specialized interdisciplinary team, warranting long-term follow-up.

Abstract
BACKGROUND Obesity surgery is associated with improvement in type 2 diabetes mellitus. Our aim was to examine the effects of biliopancreatic diversion (BPD) and laparoscopic adjustable gastric banding (LAGB) on the body mass index, fasting insulin level, glucose level, and insulin resistance in morbidly obese subjects with type 2 diabetes mellitus. The setting was the Department of Surgery, Morriston Hospital (Swansea, Wales, United Kingdom). METHODS A total of 13 morbidly obese patients (7 BPD, 6 LAGB) underwent serial measurements of fasting glucose and insulin at baseline, immediately after surgery (days 1-7), and 1, 6, and 12 months postoperatively. The homeostasis model of assessment-insulin resistance was calculated. RESULTS In the BPD group, the glucose levels had normalized by day 3 (5.6 ± 1 mmol/L) and the difference was statistically significant at 6 and 12 months postoperatively (5 ± .7 and 4.4 ± .5 mmol/L, respectively). The insulin levels had improved from day 1, and the difference was statistically significant at days 2, 5, 6, and 7 (19 ± 9, 14.2 ± 7, 15.2 ± 8, and 17.4 ± 8 mU/L, respectively). All diabetes medications were stopped on the fourth postoperative day. In the LAGB group, no statistically significant changes were seen in the glucose levels. Statistically significant changes in insulin were seen on days 1 and 2 (19 ± 13 and 13 ± 6.5 mU/L, respectively). The homeostatic model of assessment-insulin resistance had improved in both groups (BPD, 1.6 ± 1.2, P < .01; and LAGB, 4.3 ± 1.4, P < .05). CONCLUSION BPD causes immediate remission of type 2 diabetes mellitus. Leptin might play an important role in the early improvement of insulin resistance in fasting states after BPD. In the LAGB group, glucose homeostasis improved, but the patients still required diabetes medications, although the dosages were reduced.

Abstract
Gastric bypass (GBP) has proved its efficacy 30 years ago in the management of diabetes mellitus (T2DM) for severe obese patients. More recently, interesting results have been published after sleeve gastrectomy (SG) in the same indication. Between 2005 and 2008, three bariatric centers have prospectively collected the data of T2DM patients treated by laparoscopic gastric bypass (LGBP) or laparoscopic sleeve gastrectomy (LSG). Effects on hemoglobin A1c (HbA1c), pharmacological treatment and excess weight loss after 1 year of surgery have been analyzed. All patients (35 LGBP and 33 LSG) were treated with oral anti-diabetics (OAD) or insulin before surgery (32 OAD and three insulin in LGBP group and 27 OAD and six insulin in LSG group). The average body mass index (BMI) in the LGBP group was 47.9 and 50.6 kg/m² in the LSG group. At 1 year after surgery, the average HbA1c lost was 2,537 in the GBP group and 2,175 in the SG group. T2DM had resolved (withdrawal of pharmacological treatment) in 60% of the LGBP group and 75.8% of the LSG group. Reduced use of pharmacological therapy was noted in 31.42% of the LGBP group and 15.15% of the LSG group. Percentage excess weight loss and BMI lost were 56.35% and 29.75% in the LGBP group and 60.11% and 29.80% in the LSG group, respectively. During short-term follow-up, the impact on regulation of HbA1c blood level of LGBP or LSG is important. At 1 year after surgery, LSG seems to be as effective as LGBP for the management of T2DM in severely obese patients.

Abstract
BACKGROUND Roux-en-Y gastric bypass (RYGB) is an effective treatment for morbid obesity. This bariatric procedure has also been noted to resolve hyperglycaemia in up to 70% of obese diabetics. We evaluated outcomes in diabetic patients undergoing RYGB in our institution, aiming to identify factors predicting diabetes remission. METHODS One hundred ten type 2 diabetic (T2DM) patients undergoing RYGB were studied. Baseline demographics, diabetic status pre- and post-surgery and outcomes were evaluated. Outcomes were compared to a matched non-diabetic cohort. RESULTS The mean age of the patients was 45 +/- 11. The majority (70%; n = 77) were female and the mean baseline body mass index was 47 +/- 7. Mean (+/-SD range) excess weight loss at 6, 12 and 24 months was 58.3 +/- 26.4% (30.5-167%), 63.2 +/- 17.2% (0-99.2%) and 84.1 +/- 21.3% (16.5-121%), respectively. Diabetic medication was discontinued in 68.4% patients and reduced in a further 14.3%. Mean preoperative HbA1c was 7.1 +/- 2.0 and mean postoperative HbA1c 5.48 +/- 0.2. Patients with a baseline HbA1c >10 had a 50% rate of remission compared to 77.3% with an HbA1c of 6.5-7.9. The mean duration of T2DM preoperatively was 5.5 +/- 7 years. A preoperative duration of T2DM greater than 10 years was shown to significantly reduce the chances of remission (p = 0.005). CONCLUSIONS RYGB for morbid obesity achieves significant weight reduction in diabetic patients with remission of pre-surgical hyperglycaemia in the majority. The study supports findings that a shorter duration and better control of diabetes prior to surgery corresponds to a higher rate of remission. It supports the argument for early surgical intervention in the morbidly obese diabetic patient.

Abstract
BACKGROUND Symptoms of reactive hypoglycemia have been reported by patients after Roux-en-Y gastric bypass (RYGB) surgery who experience maladaptive eating behavior and weight regain. A 4-h glucose tolerance test (GTT) was used to assess the incidence and extent of hypoglycemia. METHODS Thirty-six patients who were at least 6 months postoperative from RYGB were administered a 4-h GTT with measurement of insulin levels. Mean age was 49.4±11.4 years, mean preoperative body mass index (BMI) was 48.8±6.6 kg/m2, percent excess BMI lost (%EBL) was 62.6 ± 21.6%, mean weight change from nadir weight was 8.2±8.6 kg, and mean follow-up time was 40.5±26.7 months. Twelve patients had diabetes preoperatively. RESULTS Thirty-two of 36 patients (89%) had abnormal GTT. Six patients (17%) were identified as diabetic based on GTT. All six of these patients were diabetic preoperatively. Twenty-six patients (72%) had evidence of reactive hypoglycemia at 2 h post glucose load. Within this cohort of 26 patients, 14 had maximum to minimum glucose ratio (MMGR)>3:1, 5 with a ratio>4:1. Eleven patients had weight regain greater than 10% of initial weight loss (range 4.9-25.6 kg). Ten of these 11 patients (91%) with weight recidivism showed reactive hypoglycemia. CONCLUSIONS Abnormal GTT is a common finding post RYGB. Persistence of diabetes was noted in 50% of patients with diabetes preoperatively. Amongst the nondiabetic patients, reactive hypoglycemia was found to be more common and pronounced than expected. Absence of abnormally high insulin levels does not support nesidioblastosis as an etiology of this hypoglycemia. More than 50% of patients with reactive hypoglycemia had significantly exaggerated MMGR. We believe this may be due to the nonphysiologic transit of food to the small intestine due to lack of a pyloric valve after RYGB. This reactive hypoglycemia may contribute to maladaptive eating behaviors leading to weight regain long term. Our data suggest that GTT is an important part of post-RYGB follow-up and should be incorporated into the routine postoperative screening protocol. Further studies on the impact of pylorus preservation are necessary.

Abstract
OBJECTIVE To investigate the rate of type 2 diabetes remission after gastric bypass and banding and establish the mechanism leading to remission of type 2 diabetes after bariatric surgery. SUMMARY BACKGROUND DATA Glycemic control in type 2 diabetic patients is improved after bariatric surgery. METHODS In study 1, 34 obese type 2 diabetic patients undergoing either gastric bypass or gastric banding were followed up for 36 months. Remission of diabetes was defined as patients not requiring hypoglycemic medication, fasting glucose below 7 mmol/L, 2 hour glucose after oral glucose tolerance test below 11.1 mmol/L, and glycated haemoglobin (HbA1c) <6%. In study 2, 41 obese type 2 diabetic patients undergoing either bypass, banding, or very low calorie diet were followed up for 42 days. Insulin resistance (HOMA-IR), insulin production, and glucagon-like peptide 1 (GLP-1) responses after a standard meal were measured. RESULTS In study 1, HbA1c as a marker of glycemic control improved by 2.9% after gastric bypass and 1.9% after gastric banding at latest follow-up (P < 0.001 for both groups). Despite similar weight loss, 72% (16/22) of bypass and 17% (2/12) of banding patients (P = 0.001) fulfilled the definition of remission at latest follow-up. In study 2, within days, only bypass patients had improved insulin resistance, insulin production, and GLP-1 responses (all P < 0.05). CONCLUSIONS With gastric bypass, type 2 diabetes can be improved and even rapidly put into a state of remission irrespective of weight loss. Improved insulin resistance within the first week after surgery remains unexplained, but increased insulin production in the first week after surgery may be explained by the enhanced postprandial GLP-1 responses.

Abstract
Data from the available published literature support that laparoscopic gastric bypass and laparoscopic adjustable gastric banding are safe and effective bariatric procedures for the treatment of morbid obesity. Compared with gastric bypass, gastric banding is commonly associated with a shorteroperative time and length of hospital stay, and lower perioperative morbidity. However, the medium- and long-term weight losses were consistently and dramatically better after gastric bypass. The 2 preoperative factors predictive of poor weight loss in patients with gastric banding were male gender and patients with a BMI greater than or equal to 50 kg/m2. With this knowledge, the final decision regarding gastric bypass versus gastric banding will rely on an in-depth discussion between patients and surgeons with regard to perioperative and late complication data, long-term weight loss and variability of weight loss between the 2 operations, as well as the data regarding the rate for remission of comorbidities between the 2 operations. At the current time, there is ample evidence for surgeons and patients to make a well-informed decision with regard to which operation is best for the individual patient.

Abstract
Bariatric surgery (BS) is an important treatment option for selected patients with obesity and type 2 diabetes, and laparoscopic adjustable gastric banding (LAGB) is an effective procedure for many of these patients. This treatment has become preferred in many centres because it is the simplest current option and therefore has substantially better short- and long-term safety profiles than the alternative and more invasive surgical procedures that are advocated by some. The selection of suitable patients for this and other forms of BS, optimum outcomes and follow-up of these patients requires more active involvement of diabetes teams. LAGB is a safe and effective treatment for type 2 diabetes, but just as with pharmacological therapies — diabetes teams should take more ownership of the initial decision to employ BS and acquire the skills and knowledge to ensure that patients obtain full metabolic benefit from this treatment.

Abstract
BACKGROUND Obesity is a risk factor for gestational diabetes mellitus (GDM), and bariatric surgery is an effective treatment for obesity. Our objective was to determine the association of bariatric surgery with the incidence of GDM and related complications. STUDY DESIGN We performed a retrospective study comparing rates of GDM and related outcomes (including cesarean section, large-for-gestational-age infant, shoulder dystocia, and infection) between a group of women with a delivery before bariatric surgery and a group with a delivery after bariatric surgery. We used a private insurance claims database with information on 23,594 women who had bariatric surgery between 2002 and 2006. The dataset was searched to identify women with codes for bariatric surgery and a pregnancy resulting in a delivery at greater than 22 weeks gestation. Incidences of GDM and selected delivery complications for delivery before versus after bariatric surgery were compared using Fisher exact test and logistic regression. RESULTS There were 346 women who had a delivery before bariatric surgery, and 354 had a delivery after bariatric surgery. Women with delivery after bariatric surgery had lower incidences of GDM (8% vs 27%, odds ratio (OR) 0.23, (95% CI 0.15 to 0.36) and cesarean section (28% vs 43%, OR0.53, 95% CI 0.39 to 0.72) than those with delivery before bariatric surgery. CONCLUSIONS Bariatric surgery is associated with a decreased incidence of GDM and cesarean section in subsequent pregnancies. This potential effect of bariatric surgery should be considered in the management of obese women of childbearing age. Prospective studies are needed to confirm these findings.

Abstract
RACIONAL: Os procedimentos cirúrgicos para tratamento da obesidade morbida têm sido eficientes na resolução desta afecção a curto e longo prazo. Com exceção da banda gástrica ajustável todos estes procedimentos de alguma forma são capazes de induzir a liberação de hormônios intestinais em função do desvio intestinal e desta forma exercerem um efeito metabólico. OBJETIVO: Com a intenção de obter efeitos semelhantes às operações que promovem um desvio intestinal, com as vantagens de baixa morbidade e mortalidade da BGA, foi proposto novo procedimento técnico associando à banda gástrica ajustável a um desvio jejunoileal. MÉTODO: O procedimento cirúrgico totalmente conduzido por videolaparoscopia, consiste na aplicação inicial da banda gástrica e a seguir a realização de anastomose látero-lateral a 80 cm do ângulo duodenojejunal e 120 cm da válvula ileocecal. RESULTADOS: Foram operados 10 pacientes com esta técnica, seis mulheres e quatro homens com IMC médio de 40 kg/m². A perda média de excesso de peso nos seis primeiros meses foi de 51,56%. Em quatro pacientes diabéticos houve normalização dos níveis glicêmicos e suspensão do uso da medicação antidiabética. CONCLUSÃO: Adição de desvio jejunoileal látero-lateral à banda gástrica pode melhorar a perda de peso em pacientes portadores de obesidade mórbida e contribuir para o controle da diabete tipo II.

Abstract
BACKGROUND Obesity is an increasing health problem and surgery seems to be the only treatment effective in achieving weight loss without relapse. Among bariatric techniques, many differences exist in terms of weight loss and resolution of comorbidities. Up to now, there are no prospective studies comparing long-term effects of malabsorptive vs restrictive techniques. OBJECTIVE In this study, cardiometabolic risk factors and body composition changes after malabsorptive biliointestinal bypass (BIBP) and restrictive laparoscopic adjustable gastric banding (LAGB) were compared during a 4-year follow-up. DESIGN Prospective, case-control and cohort study. PATIENTS In all, 80 obese subjects, matched for weight and age. Altogether, 40 patients underwent BIBP and 40 underwent LAGB. MEASUREMENTS Weight, body composition, fasting and post-loading plasma glucose and insulin, homeostatic model assessment index (HOMA-I), lipid profile, blood pressure (BP), erythrocyte sedimentation rate and fibrinogen were monitored at baseline, 12 and 48 months. RESULTS At 12 months after surgery, a significant reduction in body mass index, total fat mass (FM), trunk FM (trFM), trFM/legs FM (lFM) ratio (trFM/lFM), triglycerides, BP and inflammation markers was observed in both groups. BIBP patients showed a significant reduction in total cholesterol (Tot-C), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C), whereas the LAGB group showed a significant increase of HDL-C. A further improvement of all the parameters evaluated was seen in the BIBP group at 48 months after surgery. CONCLUSIONS Both bariatric procedures exerted positive effects on cardiometabolic risk factors and on weight loss in the population studied, but on the long-term period, HOMA-I, Tot-C/HDL-C ratio and body composition improvements were more evident after BIBP. We conclude that malabsorptive BIBP seems to be more effective than LAGB in treating visceral obesity and its metabolic complications.

Abstract
Bariatric surgery is the most durable intervention for severe obesity. Appropriate candidates for surgery include those with a body mass index over 40 kg/m(2), or those with a BMI over 35 kg/m(2) who also have weight-related comorbidities. Bariatric procedures are categorized as restrictive, where food intake is limited by a small gastric 'pouch'; malabsorptive, where the length of intestine available for nutrient absorption is decreased; or a combination of both. Although pure malabsorptive procedures, such as the now-historical jejunoileal bypass, achieve greater weight loss than restrictive procedures, they are generally associated with more postoperative metabolic problems. The Roux-en-Y gastric bypass is currently considered the gold standard bariatric procedure for most patients. It results in excellent weight loss with minimal complications, but does require life-long vitamin supplementation. Compliance with vitamins and supplements is also mandatory after malabsorptive procedures. With these procedures, decreased oral intake, as well as altered absorption of nutrients from the GI tract, results in potentially low blood levels of a variety of micronutrients, especially iron, vitamin B12 and folate. Bariatric surgery also improves the comorbid conditions that are associated with obesity, such as diabetes, hypertension, dyslipidemia, obstructive sleep apnea, obesity hypoventilation, gastroesophageal reflux disease, asthma, venous stasis, polycystic ovary syndrome and pseudotumor cerebri. The resolution of diabetes is secondary to weight loss and may also be due to alteration of the enteroinsular axis.

Abstract
BACKGROUND Evidence of the positive effects of gastric banding on patients with diabetes has continued to increase. The long-term follow-up of such patients, however, has been limited. The purpose of the present study was to provide the long-term outcomes of patients with diabetes undergoing laparoscopic adjustable gastric banding at our institution. METHODS From January 2002 through June 2004, 102 patients with type 2 diabetes mellitus underwent laparoscopic adjustable gastric banding. The study parameters included preoperative age, gender, race, body mass index, duration of diabetes before surgery, fasting glucose level, hemoglobin A1c (HbA1c), and medications used. Preoperative data from all patients were collected prospectively and entered into an institutional review board-approved database. Beginning in 2008, efforts were made to collect the 5-year follow-up data. RESULTS Of the 102 patients, 7 were excluded because they had not reached the 5-year follow-up point (2 patients had had the band removed early and 5 patients had died; 2 of cancer and 3 of unknown causes), leaving 95 patients for the present study. The mean preoperative age was 49.3 years (range 21.3-68.4). The mean preoperative body mass index was 46.3 kg/m(2) (range 35.1-71.9) and had decreased to 35.0 kg/m(2) (range 21.1-53.7) by 5 years of follow-up, yielding a mean percentage of excess weight loss of 48.3%. The mean duration of the diabetes diagnosis before surgery was 6.5 years. Of 94 patients, 83 (88.3%) were taking medications preoperatively, with 14.9% overall taking insulin. At 5 years postoperatively, 33 (46.5%) of 71 patients were taking medications, with 8.5% taking insulin. The mean fasting preoperative glucose level was 146.0 mg/dL. The glucose level had decreased to 118.5 mg/dL at 5 years postoperatively (P = .004). The mean HbA1c level was 7.53 preoperatively in 72 patients and was 6.58 at 5 years postoperatively in 64 patients (P <.001). Overall, diabetes had resolved (no medication requirement, with HbA1c <6 and/or glucose <100 mg/dL) in 23 (39.7%) of 58 patients and had improved (use of fewer medications and/or fasting glucose levels of 100-125 mg/dL) in 41 (71.9%) of 57 patients. The combined improvement/remission rate was 80% (64 of 80 patients). CONCLUSION Our data have demonstrated that laparoscopic adjustable gastric banding results in a substantial sustained positive effect on diabetes in morbidly obese patients, with a significant reduction in HbA1c and an 80% overall rate of improvement/remission.

Abstract
BACKGROUND Obese patients experience dramatic physical and metabolic changes in the skin and its collagen. Bariatric surgery is known to result in significant improvement in obesity-associated comorbid conditions and metabolic disturbances. The aim of this study was to evaluate skin quality following weight loss surgery and its suitability to produce an extracellular matrix for use in reconstructive procedures. METHODS During circumferential lipectomy, skin tissue was obtained from 10 patients following bariatric surgery. The samples were subjected to histologic examination and to study by differential scanning calorimetry. A retrospective review of patient records was used to determine time between bariatric and body lift procedures and to identify subject demographic and clinical data, including body mass index, excess weight loss, and comorbid conditions. RESULTS Plastic surgery followed bariatric surgery by 20.5 +/- 11 months, and patients experienced an average weight loss of 132.1 +/- 61.0 lb. Histologic evaluation of post-bariatric surgery skin samples showed a poorly organized collagen structure, elastin degradation, and regions of scar formation within macroscopically normal areas. Differential scanning calorimetry showed increased enthalpy of phase transition and decreased onset temperature for collagen denaturation in striae distensae samples compared with bulk bariatric skin samples, consistent with tissue matrix degradation in striae. CONCLUSION Skin tissue in this patient population exhibited significant signs of damage to extracellular matrix components despite the duration of time since the bariatric procedure.

Abstract
Obesity is the most important lifestyle-related risk factor for type 2 diabetes (T2DM). The prevalence of T2DM in adolescents is increasing in parallel with the increasing incidence of major obesity. In adult obese subjects, the greatest degree of T2DM prevention, improvement or recovery has been reported in patients who have undergone bariatric surgery. However, few studies are available on the benefits and risks of bariatric surgery in adolescents with T2DM. The indications for obesity surgery in this population are unusual, and should only be considered in academic settings after comprehensive interdisciplinary evaluation.

Abstract
The advent of laparoscopic adjustable gastric banding (LAGB) during the latter part of the 20th century represents a watershed in the management of chronic obesity. In this paper we provide an overview of LAGB with respect to its development, clinical outcomes, and future role. We also address current controversies, including a comparison of LAGB with Roux-en-Y gastric bypass (RYGBP). At present LAGB seems to be increasing in popularity in the United States, whereas in Europe there seems to be a trend away from gastric banding toward RYGBP. Optimal outcomes after LAGB are a function of correct laparoscopic technique, an experienced surgical team, a well-engineered device, and intensive long-term follow-up. The majority of studies show that LAGB is an extremely safe and effective procedure, with an operative mortality of 0-0.1% and excess weight loss (%EWL) of 50-60%. Commensurate with this degree of weight loss, almost all studies show substantial improvements in obesity-related co-morbidities, such as hypertension, type II diabetes, and dyslipidemia. In addition, LAGB has been shown to be both safe and effective in the super-obese, in adolescents, and in older patients and can be delivered as an ambulatory procedure. Operative mortality and early complication rates are significantly higher for RYGBP and, whilst gastric bypass results in greater weight loss than LAGB in the first 2 years, at 3 years and beyond the difference appears to be less marked. Overall, LAGB provides a safe, effective intervention for obese patients and remains our first-choice procedure for bariatric surgery.

Abstract
BACKGROUND Gastric bypass results in the rapid resolution of type 2 diabetes. No causal evidence exists to link specific gut hormone changes with improvements in glucose homeostasis post-operatively. We hypothesized that surgical augmentation of the glucoregulatory factor GLP-1 would improve glucose tolerance in diabetic GK rats. We compared two procedures that increase distal small bowel stimulation, ileal interposition (IT), and duodenal-jejunal exclusion (DJE). METHODS DJE, IT, DJE Sham, or IT Sham were performed in GK rats. Glucose tolerance was tested at 4 and 6 weeks, the latter with and without Exendin-[9-39], a GLP-1 receptor antagonist. Small bowel segments were harvested for GLP-1 protein content 2 weeks after DJE or Sham surgery. RESULTS Despite similar weight profiles, a significant improvement in the OGTT was noted at 4 weeks after DJE and IT. Plasma GLP-1 levels were significantly elevated after DJE and IT. Intestinal GLP-1 was increased in the mid-jejunum and ileum after DJE. Exendin-[9-39] abolished the improvement in glucose tolerance after DJE. CONCLUSIONS DJE increased GLP-1 secretion and improved glucose tolerance, an effect that was reversed by GLP-1 receptor antagonism. This study provides direct evidence that improvement of glucose tolerance following a gastric bypass-like surgery is mediated by enhanced GLP-1 action.

Abstract
Background Bariatric surgery is able to improve glucose and lipid metabolism, and cardiovascular function in morbid obesity. Aim of this study was to compare the long-term effects of malabsorptive (biliary pancreatic diversion, BPD), and restrictive (laparoscopic gastric banding, LAGB) procedures on metabolic and cardiovascular parameters, as well as on metabolic syndrome in morbidly obese patients. Methods 170 patients studied between 1989 and 2001 were called back after a mean period of 65 months. 138 patients undergoing BPD (n = 23) or LAGB (n = 78), and control patients (refusing surgery and treated with diet, n = 37) were analysed for body mass index (BMI), blood glucose, cholesterol, and triglycerides, blood pressure, heart rate, and ECG indexes (QTc, Cornell voltage-duration product, and rate-pressure-product). Results After a mean 65 months period, surgery was more effective than diet on all items under evaluation; diabetes, hypertension, and metabolic syndrome disappeared more in surgery than in control patients, and new cases appeared only in controls. BPD was more effective than LAGB on BMI, on almost all cardiovascular parameters, and on cholesterol, not on triglyceride and blood glucose. Disappearance of diabetes, hypertension, and metabolic syndrome was similar with BPD and with LAGB, and no new cases were observed. Conclusion These data indicate that BPD, likely due to a greater BMI decrease, is more effective than LAGB in improving cardiovascular parameters, and similar to LAGB on metabolic parameters, in obese patients. The greater effect on cholesterol levels is probably due to the different mechanism of action.

Frezza EE, Wozniak SE, Gee L, Wacthel M. Is there any role of resecting the stomach to ameliorate weight loss and sugar control in morbidly obese diabetic patients? Obes Surg 2009; 19:1139-42. [PMID: 19484314 DOI: 10.1007/s11695-009-9868-9] [Citation(s) in RCA: 12] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2009] [Accepted: 05/13/2009] [Indexed: 01/31/2023]
Abstract
BACKGROUND Among the restrictive procedures the role of restrictive vs. resecting the stomach is still ambiguous. This study evaluate which is the role of the stomach with respect to blood glucose levels (BG) and percent excess weight loss (EWL) over the 18 months after restrictive procedures in morbid obese diabetic patients. METHODS We retrospectively compared a group of patients who underwent partial gastrectomy (just part of the gastric body) with gastric banding (GBSR; n=27), sleeve gastrectomy (part of gastric body and complete fundus resection; LSG; n=53) to laparoscopic gastric banding (LAGB; n=100). Differences among groups at 3, 6, 12, and 18 months were evaluated by analysis of variance. The three cohorts were diabetic patients similar in BMI, age, and gender. RESULTS At 12 and 18 months, LSG had higher EWL (P<0.05) and lower BG (P<0.05) than did either LAGB or GBSR. There were no operative deaths. COMPLICATIONS LAGB-two staple-line oozing, two wound infections; LSG-one hemorrhage, two staple-line oozing, two leaks; GBSR-one hemorrhage, two wound infections. All complications were readily treated. CONCLUSIONS LSG provides better weight loss and glucose control at 1 year and 1.5 years after surgery than does either LAGB or GBSR, suggesting that gastric fundus resection plays an important, not yet well-defined, role.

Early U.S. outcomes after laparoscopic adjustable gastric banding in patients with a body mass index less than 35 kg/m2. Surg Endosc 2009; 23:1569-73. [PMID: 19263156 DOI: 10.1007/s00464-009-0341-6] [Citation(s) in RCA: 36] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2008] [Revised: 06/20/2008] [Accepted: 01/08/2009] [Indexed: 01/14/2023]
Abstract
BACKGROUND Many mildly to moderately obese individuals with a body mass index (BMI) lower than 35 kg/m(2) have serious diseases related to their obesity. Nonsurgical therapy is ineffective in the long term, yet surgery has never been made widely available to this population. METHODS Between 2002 and 2007, 53 patients with a BMI lower than 35 kg/m(2) underwent laparoscopic adjustable gastric banding at our institution. Data on all these patients were collected prospectively and entered into an institutional review board-approved electronic registry. The study parameters included preoperative age, gender, BMI, presence of comorbidities, percentage of excess weight loss (%EWL), and resolution of comorbidities. RESULTS The mean preoperative age of the patients was 46.9 years (range, 16-68 years), and the mean preoperative BMI was 33.1 kg/m(2) (range, 28.2-35.0 kg/m(2)). Of the 53 patients, 49 (92%) had at least one obesity-related comorbidity. The mean BMI decreased to 28.1 +/- 2.4 kg/m(2), 25.8 +/- 2.9 kg/m(2), and 25.8 +/- 3.1 kg/m(2) and mean %EWL was 48.3 +/- 17.6, 69.9 +/- 28.0, and 69.7 +/- 31.7 at 0.5, 1, and 2 years, respectively. Substantial improvement occurred for the following comorbidities evaluated: hypertension, depression, diabetes, asthma, hypertriglyceridemia, obstructive sleep apnea, hypercholesterolemia, and osteoarthritis. There was one slip, two cases of band obstruction (from food), two cases of esophagitis, and two port leaks, but no mortality. CONCLUSION The authors are very encouraged by this series of low-BMI patients who underwent laparoscopic adjustable gastric banding. Their weight loss has been excellent, and their complications have been acceptable. Their comorbidities have partially or wholly resolved. With further study, it is reasonable to expect alteration of the weight guidelines for bariatric surgery to include patients with a BMI lower than 35 kg/m(2).

Abstract
BACKGROUND Elevated hemoglobin A1c (HbA1c) values are known to increase the risk of diabetic retinopathy, nephropathy, and peripheral neuropathy. The current guidelines recommend maintaining HbA1c values at <7%. We assessed the effect of laparoscopic Roux-en-Y gastric bypass surgery (LRYGB) on HbA1c values in diabetic patients compared with a conventionally treated cohort. METHODS A retrospective review of a prospective bariatric database identified diabetic patients who had undergone LRYGB from 2001 to 2005. A cohort of conventionally treated obese (body mass index >35 kg/m(2)) diabetic patients was matched by age and gender. The inclusion criteria consisted of a preoperative/initial HbA1c and 2 postoperative/follow-up HbA1c values compiled from our institution's comprehensive electronic medical record system. The patients in the LRYGB cohort were also required to have had a 1-year postoperative weight recorded. Statistical analysis was performed using the Student t test. RESULTS Each cohort consisted of 40 women (78.4%) and 11 men (21.6%). The mean age was 48.8 +/- 8.3 years for the surgical cohort and 48.2 +/- 8.3 years for the conventionally treated cohort. The mean body mass index was 47.7 +/- 5.7 kg/m(2) preoperatively for the surgical cohort and 45.1 +/- 5.7 kg/m2 initially for the conventionally treated cohort. The mean preoperative/initial HbA1c was 7.5% +/- 1.4% and 7.0% +/- 1.1% for the surgical and conventionally treated groups, respectively. At 1 year, HbA1c results were available for 46 LRYGB and 41 conventionally treated patients. The corresponding mean HbA1c values were 5.8% +/- 1.1% and 7.0% +/- .9% (P = .001). At 3 years, the mean HbA1c was 6.1% +/- 1.2% and 7.8% +/- 1.5% for 28 surgical and 36 conventionally treated patients, respectively (P = .001). The surgical patients' use of oral hypoglycemic medications and/or insulin decreased from 84.3% before surgery to 22.4% at 1 year postoperatively. CONCLUSION The patients who underwent LRYGB had a significant and sustained improvement in the HbA1c value compared with the conventionally treated obese patients with type 2 diabetes mellitus.

Laparoscopic ileal interposition associated to a diverted sleeve gastrectomy is an effective operation for the treatment of type 2 diabetes mellitus patients with BMI 21-29. Surg Endosc 2008; 23:1313-20. [PMID: 18830750 DOI: 10.1007/s00464-008-0156-x] [Citation(s) in RCA: 78] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2008] [Revised: 07/29/2008] [Accepted: 08/13/2008] [Indexed: 12/18/2022]
Abstract
BACKGROUND The objective of this study is to evaluate the clinical results of the laparoscopic interposition of a segment of ileum into the proximal duodenum associated to a sleeve gastrectomy (II-DSG) in order to treat patients with type 2 diabetes mellitus (T2DM) and body mass index (BMI) 21-29 kg/m2. PATIENTS AND METHODS The laparoscopic procedure was performed in 69 patients, 22 female and 47 male. Mean age was 51 years (range 41-63 years). Mean BMI was 25.7 (21.8-29.2) kg/m2. All patients had the diagnosis of T2DM for at least 3 years and evidence of stable treatment with oral hypoglycemic agents and or insulin for at least 12 months. Insulin therapy was used by 44% of the patients. Mean duration of T2DM was 11 years (range 3-18 years). Dyslipidemia was diagnosed in 72.5% and hypertension in 66.7%. Nephropathy was characterized in 29% of the patients, retinopathy in 26.1%, and neuropathy in 24.6%. RESULTS Overall, 95.7% of the patients achieved adequate glycemic control (Hb(A1c) < 7%) without antidiabetic medication. Hb(A1c) below 6% was achieved by 65.2%. Mean postoperative follow-up was 21.7 months (range 7-42 months). Mean postoperative BMI was 21.8 kg/m2. There was no conversion to open surgery. Median hospital stay was 3.4 days (range 2-58 days). Major postoperative complications were diagnosed in 7.3%. There was no mortality. Fasting glycemia decreased from a mean of 218 to 102 mg/dl, postprandial glycemia from 305 to 141 mg/dl, and homeostasis model assessment of insulin resistance (Homa-IR) from 5.2 to 0.77. All associated comorbidities and complications related to T2DM had significant improvement or control. Arterial hypertension was controlled in 91.3%. Macroalbuminuria was no longer observed. Microalbuminuria resolved in 87.5% of patients. Hypercholesterolemia was normalized in 95% and hypertriglyceridemia in 92% of patients. CONCLUSIONS Laparoscopic II-DSG was an effective operation in controlling T2DM in a nonobese (BM < 30 kg/m2) population. Associated diseases and related complications were also improved. A longer follow-up period is needed.
