BackgroundRevisional bariatric surgery is increasing in frequency, but the morbidity and efficacy have not been well defined. The primary aim of this study was to determine the clinical efficacy with respect to weight loss, and associated morbidity, of revisional bariatric surgery in an academic university hospital bariatric surgery program.MethodsA retrospective review of all patients who underwent revisional bariatric surgery for failed primary restrictive procedures, including gastroplasty and gastric bypass, but not including gastric banding or malabsorptive procedures, during a 10-year period at a single university hospital was performed. The perioperative morbidity and long-term weight loss and clinical results were determined from the medical charts.ResultsA total of 41 patients met the inclusion criteria. The primary bariatric procedures included vertical banded gastroplasty in 20 and Roux-en-Y gastric bypass in 21. The indications for revisional surgery included poor weight loss, weight regain, and various technical problems, including anastomotic stenosis and ulcer. The major morbidity rate was 17%. No patients died. The weight loss results varied depending on the indication for the revisional surgery and reoperative solution applied. The resolution of technical problems was achieved in all patients.ConclusionRevisional bariatric surgery can be performed with minimal mortality, albeit significant morbidity. The efficacy with respect to weight loss appeared acceptable, although the results were not as good as those after primary bariatric surgery. The analysis of patient subsets stratified by surgical history and revisional strategy provided important insights into the mechanisms of failure and efficacy of different revisional strategies.  相似文献

Bariatric surgery is a safe and effective method for achieving durable weight loss for patients with morbid obesity. Gastric restrictive procedures include vertical banded gastroplasty and gastric banding. Malabsorptive procedures include long-limb gastric bypass, biliopancreatic diversion, and biliopancreatic diversion with duodenal switch. The gastric bypass has features of both restriction and malabsorption. The laparoscopic approach to bariatric surgery has substantially improved postoperative recovery. Careful patient selection and preoperative work-up are extremely important. A number of medical comorbidities are improved after surgically-induced weight loss.  相似文献

Background: Morbidly obese patients who undergo purely restrictive bariatric operations may fail to maintain satisfactory long-term results. In an attempt to achieve the best possible outcome after restrictive procedures, we have employed preoperative selection criteria and are following this selected patient group over time in order to evaluate longterm success. Materials and Methods: From June 1994 through August 2000, 166 morbidly obese patients underwent various bariatric procedures at our institution. Of these patients, 35 underwent vertical banded gastroplasty (VBG) based on selection criteria, including degree of obesity and dietary habits and eating behavior. All patients were seen at 1, 3, 6, 9, and 12 months postoperatively and yearly thereafter. Average follow-up time now is 4.1 years (29-75 mos.), and follow-up is 100%. A multivitamin and mineral supplement is administered to all patients for at least 6 months. Radiology examination is performed in all patients on the 4th postoperative day and at each yearly visit, in order to check for staple-line disruption and stomal stenosis. Results: Early postoperative morbidity was 5.7%. Late postoperative morbidity was 22.8%. A significant number of patients had some degree of stomal stenosis as shown by radiology examination, but to date there has been no need for surgical revision. There has been no early or late mortality.Weight loss results expressed as average percent excess weight loss (% EWL) were as follows: 61% (28-90) at 1 year, 61% (20-90) at 2 years, 57% (13-91) at 3 years, 56% (25-87) at 4 years and 37% (24-59) at 5 years following surgery. A significant number of patients with excellent weight loss had a high frequency of vomiting. Evaluation by BAROS showed that 25% of patients had an overall unsatisfactory outcome. Anemia and iron deficiency were found in 46% and 32% ofVBG patients respectively.Recurrence of preexisting comorbidities was significant if lost weight was regained. Conclusions: In spite of preoperative selection of patients for VBG, a significant percentage of patients had poor overall results in terms of weight loss, quality of life, and resolution of preexisting comorbidities. For these reasons and based on the long-term results published by others, VBG is no longer our preferred surgical option in morbidly obese patients.  相似文献

Background

Bariatric surgery is effective at achieving weight loss in the severely obese, with the majority of procedures performed laparoscopically. A short-term pre-operative energy restrictive diet is widely adopted to enable surgery by reducing liver size and improving liver flexibility. However, the dietary approach is not standardised. This observational study reports on pre-operative restrictive diets in use across bariatric services in the UK.

Methods

Between September and November 2012, information was collected from bariatric services on current or past pre-operative diets, and any research providing evidence for the use or modification of their diets.

Results

Around one third of bariatric services (28) in the UK responded, with a total of 49 diets in current use. Types of diet include low energy, low carbohydrate and liquid, with 59 % offering low energy/low carbohydrate food-based, 21 % milk/yoghurt, 18 % meal replacement (liquid) and 2 % clear liquid. Diet duration varies between 7 and 42 days. Limited anecdotal evidence was provided by services evaluating the pre-operative diet, and its alternative approaches, with dietary choice primarily clinician-led.

Conclusions

This study has highlighted variability and lack of consensus in the form of pre-bariatric surgery diet used across different centres. Further research comparing outcomes for alternative diets would support best practice in the future.  相似文献

Background: Obesity is a chronic, multifactorially caused disease with serious somatic and psychosocial comorbidity as well as economical consequences. In the Netherlands, between 1993 and 1997, the prevalence of morbid obesity was 0.2% for men and 0.6% for women. Although bariatric surgery generally is an effective intervention, it does not lead to equal results in every patient. The long-term efficacy is predominantly determined by compliance to adequate dietary rules in which psychosocial factors can play a major role. Methods: Questionnaires were sent to the surgery departments of all hospitals in the Netherlands. Subsequently, a second questionnaire was sent to clinical psychology departments of hospitals which perform bariatric surgery. Results: In 28 Dutch hospitals (19%), bariatric surgery is being performed, mostly using restrictive procedures. Almost all hospitals have a multidisciplinary selection-process, and all surgeons and psychologists use multiple selection-criteria. Regarding these criteria, there is more consensus between surgeons than between psychologists. In most hospitals, patients are psychologically assessed prior to surgery. However, postoperative assessment is relatively rare, as is preoperative and postoperative psychological treatment. Conclusion: In the Netherlands, bariatric surgery is still relatively uncommon and mostly limited to restictive procedures. Irrespective of BMI and eating behavior, the majority of patients will be offered a restrictive procedure. The involvement by the psychological and/or psychiatric discipline is not optimal yet; especially, postoperative assessment and pre- and postoperative treatment are not frequently performed, in spite of the fact that these programs can enhance the success rate of bariatric surgery.  相似文献

Background  

Previous studies have suggested that patients who are defined as so-called sweet eaters have more difficulties to lose weight and to maintain weight loss after both conservative treatment and restrictive bariatric surgery, such as gastric banding. There is, however, no agreement on the definition of sweet eating. Also, a questionnaire to measure sweet eating is not available. Therefore, the aim of our study was to agree on a definition of sweet eating and to construct a valid and reliable questionnaire that might be of help to assess the influence of sweet eating on weight loss after bariatric surgery.  相似文献

One hundred and thirteen morbidly obese patients underwent bariatric surgery. Mean preoperative percentage above ideal weight was 98.3% (SD 30.0%). Mean percentage above ideal weight eighteen months after operation was 19.5% (SD 23.8%). Fifteen patients (13.3%) required pre-operative weight loss because of respiratory dysfunction and raised PaCO2. One patient developed asthma in the postoperative period. There were no other clinical postoperative respiratory complications. 40% of patients however did show radiological evidence of basal pulmonary atelectasis on the initial postoperative chest X-ray. All patients had pre-operative cardiological screening: there were no cardiac complications except one case of atrial fibrillation. One patient suffered a proven pulmonary embolus and recovered. Six patients (5.3%) required correction of a pre-operative potassium deficit. No episode of gastric acid aspiration syndrome occurred. 58% of patients presenting for obesity surgery had identifiable psychopathology. Despite strict pre-operative psychiatric screening, 15% of patients coming to operation required postoperative psychiatric management.  相似文献

Psychosocial Predictors of Success following Bariatric Surgery   总被引:3,自引:3,他引:0  
Background: Bariatric surgery is the treatment of choice for morbid obesity, but it does not lead to equal results in every patient. In addition to surgery, a number of non-surgical and psychological factors may influence patients' ability to adjust to the postoperative condition. Understanding the relationship between potential predictive variables and success after bariatric surgery will enable better patient selection, and the development of interventions to improve outcome. Methods: A systematic literature search identified relevant variables, such as demography, preoperative weight, motivation, expectations, eating behavior, psychological functioning, personality, and psychiatric disorders, which may have predictive value for success after bariatric surgery. Results: Greater success following bariatric surgery appears to occur in patients who are young and female, and have a high self-esteem, good mental health, a satisfactory marriage, and high socio-economic status, who are self-critical and cope in a direct and active way, are not too obese, were obese before the age of 18, suffer from and are concerned about their obesity, have realistic expectations and undisturbed eating behaviors. Occasionally, these variables may have poor or no predictive value. Although reliable predictors are lacking, most treatment teams propose their own exclusion criteria. Conclusion: The existing literature about potential predictors of success after bariatric surgery is far from conclusive; it is still uncertain which factors can predict success. Even where psychosocial functioning does not predict outcome, it is important to identify patients' characteristics which may be linked to their prognosis and to provide necessary pre- and postoperative psychosocial interventions.  相似文献

Background: The outcomes and initial results of laparoscopic sleeve gastrectomy were evaluated. Methods: A prospective study of the initial 10 patients who underwent laparoscopic sleeve gastrectomy (LSG) was performed. Study endpoints included operative time, complication rates, hospital length of stay and percentage of excess weight loss (%EWL). Results: There were 5 women and 5 men, with mean age 43 years (range 31 to 52). Mean preoperative weight was 182 kg (range 125-247 kg), with mean preoperative BMI 64 (range 61-80). Indication for LSG was related to BMI in all patients. 1 patient had previous restrictive bariatric surgery. Mean operative time was 2 hours (range 1.5-2.5). No patient required conversion. There were no postoperative complications nor mortality. Median hospital stay was 7.2 days. Average %EWL and BMI at 1 year were 51% and 23 kg/m2, respectively. Conclusion: LSG can be safely integrated into a bariatric surgical program with good results in terms of weight loss and quality of life. LSG can be a firststage procedure before gastric bypass or duodenal switch or a one-stage restrictive procedure if longterm results are good. LSG should be considered as a surgical option in the bariatric field.  相似文献

Background: The relative risks and effectiveness of primary and revision operations done to produce weight loss are of interest both from a patient care and an economic perspective. The possibility that patients requiring revision surgery comprise a treatment resistant subgroup who are more likely to have post-operative complications is a valid concern. Methods: The records of all patients having bariatric procedures since January of 1970 were evaluated for weight loss and complications. Results: Most revisions were from jejunoileal bypass or a gastric restrictive procedure. Early complications were significantly more common following revision surgery (19%) than after primary procedures (6%), although late and combined early and late complication rates were similar. Operative mortality was lower following primary procedures (2/382) than revisions (1/75). Cholecystectomy was a common sequela following primary procedures but did not occur after revision procedures. Regardless of surgical category, weight loss after revision was equivalent to weight loss after primary procedures. Conclusions: Weight loss following revisional bariatric surgery is equivalent to weight loss following a primary operation of the same type. Although mortality and early complications are more common after revisional bariatric surgery, the frequency of late complications is not different. In all groups wound infections and hernias were relatively common complications and cholecystectomies are rare after revisional bariatric operations.  相似文献

OBJECTIVE: To identify sociodemographic and clinical predictors of patient selection in bariatric surgery. SUMMARY BACKGROUND DATA: Population-based studies suggest that bariatric surgery patients are disproportionately privately insured, middle-aged white women. It is uncertain whether such disparities are due to surgeon decisions to operate, differences among morbidly obese individuals in access to surgery, or patients' personal preferences regarding surgical treatment. METHODS: We conducted a national survey of 1343 U.S. bariatric surgeons. The questionnaire contained clinical vignettes generated using a balanced fractional factorial design. For each of 3 hypothetical patients unique in age, race, gender, body mass index (BMI), comorbidities, social support, functional status, and insurance, respondents were asked if they would operate. Logistic regression was used to determine the odds of selection for each characteristic while controlling for the other 7 characteristics. Subset analyses were also performed using combinations of BMI and comorbidities. RESULTS: A total of 62.5% of eligible surgeons responded (n = 820). Patient race did not influence surgeon decisions to operate. Hypothetical patient age, BMI, and social support were most influential. In the subgroup of patients who did not meet current NIH BMI and comorbidity criteria for bariatric surgery, male sex (odds ratio [OR], 0.33; 95% confidence interval [CI], 0.14-0.76) was associated with decreased odds of selection. Overall, younger age (OR, 0.09; 95% CI, 0.07-0.11), older age (OR, 0.70; 95% CI, 0.56-0.90), limited functional status (OR, 0.66; 95% CI, 0.52-0.82), poor social support (OR, 0.37; 95% CI, 0.30-0.47), self-pay (OR, 0.72; 95% CI, 0.57-0.91), and public insurance (OR, 0.54; 95% CI, 0.43-0.67) were associated with decreased odds of selection. BMI and comorbidity criteria influenced the magnitude of these effects. CONCLUSIONS: Patient race did not play a role in surgeon decisions to operate. Further research should examine the roles of unequal access to bariatric surgery and differing socio-cultural perceptions of morbid obesity on racial disparities. The influence of patient age, gender, insurance status, social support, and functional status on decisions to operate was mitigated by BMI and comorbidities. Policy-makers currently debating BMI and comorbidity criteria for bariatric surgery should also consider guidelines pertaining to these sociodemographic issues that influence patient selection in bariatric surgery.  相似文献

Background

The indications for bariatric interventions consist of the objectives to improve the quality of life and to prolong survival by remission of obesity-associated comorbidities. Until now the selection criteria for patients to undergo surgery which allow a prediction of therapeutic success are obscure.

Objective

The aim of the study was to identify the prerequisites for selection of overweight and obese patients to undergo bariatric surgery.

Results

Obesity per se is a proven indication for bariatric surgery due to the associated increase in mortality; however, not all obese patients can be considered for weight reduction surgery. A decisive factor for patient selection is the evidence of behavioral change regarding nutrition, composition and frequency of meals as well as increased ambulation. In patients with psychiatric diseases and behavioral disorders responsible for obesity a specific therapy is mandatory as well as intensive counseling and adherence to a lifelong follow-up.

Discussion

It seems that therapeutic success on a long-term basis is only guaranteed by behavioral changes. Preoperative multimodal therapy does not influence the outcome but it seems possible that such treatment may contribute to increased adherence to the behavior necessary for therapeutic success. Nevertheless, such treatment must not constitute a barrier against bariatric surgery. However, patients who are not willing to change their pathological behavior do not qualify for weight-reducing surgery because otherwise therapeutic success is questioned.  相似文献

Background: The search for replicable predictors of the outcomes of surgical intervention for obesity has proven challenging, with patient selection being a recurrent theme in bariatric literature. Methods: In this study, 20 gastric bypass patients were interviewed at an average of 2 years following surgery. Subjects provided extensive data relating to their characteristics and experiences. Results: Statistical analyses were undertaken to establish likely predictors of success, both in terms of percentage of excess weight lost and in broader terms. It was found that self-esteem, some scales of the Adjective Checklist, and valuing of food and eating related to a successful outcome. Conclusion: Recommendations are made regarding an interview schedule for pre-operative assessment, and a prospective study to evaluate its predictive power is proposed.  相似文献

Background: At the turn of the 21st century, obesity is the epidemic with the greatest prevalence in the United States. Fifteen million people, 1 out of 20, in this country have a body mass index (BMI) ≥35 kgm2. Obesity is not only a medical problem, but also a social, psychological, and economic problem. At present, the morbidly obese are refractory to diet and drug therapy, but have a substantial, sustained weight loss after bariatric surgery. Methods: This chronology of the landmark operations in bariatric surgery is based on a review of the medical literature. Results: Bariatric surgery can be classified into 4 categories: malabsorptive procedures, malabsorptive/restrictive procedures, restrictive procedures, and other, experimental procedures. The prototype of malabsorptive procedures and the first operation performed specifically to induce weight loss was the jejunoileal bypass. The problems associated with this operation caused its demise. Today's popular malabsorptive procedures are the biliopancreatic diversion and the duodenal switch. Malabsorptive /restrictive surgery currently is predicated on the Roux-en-Y gastric bypass, both the traditional short-limb, and the long-limb for the super obese. Restrictive procedures are represented by the banded and ringed vertical gastroplasty, as well as gastric banding. Experimental procedures include gastric pacing. All of these operations can be performed by open surgery and laparoscopically. Conclusions: Since bariatric surgery is the only broadly successful treatment for morbid obesity,it is incumbent on all physicians to be familiar with current bariatric operations, and to understand the evolution of bariatric surgery.  相似文献

BackgroundThe low-grade inflammatory condition present in morbid obesity is thought to play a causative role in the pathophysiology of insulin resistance (IR). Bariatric surgery fails to improve this inflammatory condition during the first months after surgery. Considering the close relation between inflammation and IR, we conducted a study in which insulin sensitivity was measured during the first months after bariatric surgery. Different methods to measure IR shortly after bariatric surgery have given inconsistent data. For example, the Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) levels have been reported to decrease rapidly after bariatric surgery, although clamp techniques have shown sustained insulin resistance. In the present study, we evaluated the use of steady-state plasma glucose (SSPG) levels to assess insulin sensitivity 2 months after bariatric surgery.MethodsInsulin sensitivity was measured using HOMA-IR and SSPG levels in 11 subjects before surgery and at 26% excess weight loss (approximately 2 months after restrictive bariatric surgery).ResultsThe SSPG levels after 26% excess weight loss did not differ from the SSPG levels before surgery (14.3 ± 5.4 versus 14.4 ± 2.7 mmol/L). In contrast, the HOMA-IR values had decreased significantly (3.59 ± 1.99 versus 2.09 ± 1.02).ConclusionDuring the first months after restrictive bariatric surgery, we observed a discrepancy between the HOMA-IR and SSPG levels. In contrast to the HOMA-IR values, the SSPG levels had not improved, which could be explained by the ongoing inflammatory state after bariatric surgery. These results suggest that during the first months after restrictive bariatric surgery, HOMA-IR might not be an adequate marker of insulin sensitivity.  相似文献

Bariatric surgery has become more common due to the worldwide obesity epidemic. A shift from open to laparoscopic surgery has occurred in the last 2 decades, because of its advantages. Revisional surgery after bariatric procedures is becoming an important issue, and restrictive procedures account for a large proportion of these interventions. Three restrictive procedures are currently in use: laparoscopic adjustable gastric banding, laparoscopic sleeve gastrectomy and vertical banded gastroplasty. The first two procedures are more commonly used, and the third is losing favor with surgeons. All three have proven effective, but less than malabsortive or combined procedures. The reasons to reoperate upon a patient and convert a previous bariatric procedure to a different one are failure of the operation, due to insufficient weight loss, or weight regain (secondary obesity); or complications like penetration, infection, bleeding, obstruction, dysphagia, and gastroesophageal reflux, among others. This review will describe the complications or failures leading to the a second operation; the conditions present after the first procedure and the presence of failure or complications; the technical steps required to be taken; and the outcomes and what can be expected afterwards.  相似文献

HYPOTHESIS: Bariatric surgery performed at US academic centers is safe and associated with low mortality. DESIGN: Multi-institutional consecutive cohort study. SETTING: Academic medical centers. PATIENTS AND INTERVENTIONS: We audited the medical records from 40 consecutive bariatric surgery cases performed between October 1, 2003, and March 31, 2004, at each of the 29 institutions participating in the University HealthSystem Consortium Bariatric Surgery Benchmarking Project. All medical records that met inclusion criteria (patient age, >17 and <65 years; and body mass index [calculated as weight in kilograms divided by the square of height in meters], 35-70) and exclusion criteria (previous bariatric surgery) were reviewed and data were collected on a standardized form. MAIN OUTCOME MEASURES: Demographic data, operative time, blood loss, transfusion requirement, complications, readmission, reoperation, and in-hospital and 30-day mortality. RESULTS: Data from 1144 bariatric surgery cases were reviewed from 29 University HealthSystem Consortium institutions. The specific bariatric procedures included gastric bypass (91.7%), gastroplasty or gastric banding (8.2%), and biliopancreatic diversion (0.1%). For gastric bypass procedures (n = 1049), the mean patient age was 43 years and mean body mass index was 49; 76% of procedures were performed laparoscopically, with a conversion rate of 2.2%; the overall complication rate was 16%, with an anastomotic leakage rate of 1.6%; the 30-day readmission rate was 6.6%; and the 30-day mortality rate was 0.4%. For restrictive procedures (n = 94), the mean patient age was 45 years and mean body mass index was 45; 92% of procedures were performed laparoscopically with no conversion; the overall complication rate was 3.2%; the 30-day readmission rate was 4.3%; and the 30-day mortality rate was 0%. CONCLUSIONS: Within the context of the 2004 University HealthSystem Consortium Bariatric Surgery Benchmarking Project, the risk for death within 30 days after bariatric surgery at academic centers is less than 1%. In addition, the practice of bariatric surgery at these centers has shifted from open surgery to predominately laparoscopic surgery. These quality-controlled outcome data can be used as a benchmark for the practice of bariatric surgery at most US hospitals.  相似文献

Background

There are growing numbers of patients who require revisional bariatric surgery due to the undesirable results of their primary procedures. The aim of this study was to review our experience with bariatric patients undergoing revisional surgery.

Methods

We conducted a retrospective analysis to review the indications for revisional bariatric procedures and assess their postoperative outcomes.

Results

From 04/04 to 01/11, 2,918 patients underwent bariatric surgery at our institution. A total of 154 patients (5.3 %) of these cases were coded as revisional procedures. The mean age at revision was 49.1?±?11.3 and the mean BMI was 44.0?±?13.7 kg/m2. Revisional surgery was performed laparoscopically in 121 patients (78.6 %). Laparoscopic revisions had less blood loss, shorter length of hospital stay, and fewer complications compared to open revisions. Two groups (A and B) were defined by the indication for revision: patients with unsuccessful weight loss (group A, n?=?106) and patients with complications of their primary procedures (group B, n?=?48). In group A, 74.5 % of the patients were revised to a bypass procedure and 25.5 % to a restrictive procedure. Mean excess weight loss was 53.7?±?29.3 % after revision of primary restrictive procedures and 37.6?±?35.1 % after revision of bypass procedures at >1-year follow-up (p?<?0.05). In group B, the complications prompting revision were effectively treated by revisional surgery.

Conclusions

Revisional bariatric surgery effectively treated the undesirable results from primary bariatric surgery. Laparoscopic revisional surgery can be performed after both failed open and laparoscopic bariatric procedures without a prohibitive complication rate. Carefully selected patients undergoing revision for weight regain have satisfactory additional weight loss.  相似文献

A dramatic increase in bariatric surgery has increased the number of patients with redundant skin/large panniculus after massive weight loss. This is best treated by surgery; however, not all patients with redundant skin/panniculus get authorization from insurance providers. There are certain insurance coverage criteria for panniculectomy that need to be met by patients for approval. Our search also demonstrated that there are not established criteria/guidelines for different body parts such as inner arms and thighs other than the pannus amongst third-party payers. These cases are appraised individually by third-party payers based on presented signs and symptoms. It is of utmost importance that members of a bariatric team are knowledgeable on these guidelines and should be able to discuss if necessary; however, currently utilized criteria should be discussed with patients, preferably in pre-bariatric surgery phase, and ideally by a plastic surgeon. Advantages are several-fold and discussed in the article.  相似文献
