Background

Occurrences of mesenchymal tumors have been more recognized in recent years, and the incidental diagnosis of these lesions during bariatric surgery has been previously reported.

Objective

To describe the cases of incidentally diagnosed mesenchymal tumors during consecutive bariatric surgeries.

Setting

Private health-providing service, Brazil.

Methods

A retrospective population-based study, which enrolled individuals who consecutively underwent Roux-en-Y gastric bypass at a single center from January 2006 through July 2016.

Results

Of 1502 individuals, there were 16 cases (1.1%) of confirmed mesenchymal tumors. Of these 16 cases, 14 (87.5%) were gastrointestinal stromal tumors and 2 (12.5%) were leiomyomas. The affected individuals were significantly older (aged 46.2 ± 6.3 versus 35.4 ± 7.2 yr; P = .00031), presented a lower body mass index (38.2 ± 5.1 versus 45.3 ± 8.1 kg/m2; P<.00001), and had a lower weight (102.1 ± 17.9 versus 121.1 ± 7.4 kg; P = .00321). None of the individuals presented reported relapses of the mesenchymal tumors.

Conclusion

The possibility of incidental gastric mesenchymal tumors during bariatric surgery should not be neglected; a careful inventory of the stomach at the beginning of the procedure and resection of lesions found are mandatory.

Background

Bariatric procedures are increasingly being used, but data on bowel habits are scarce.

Objectives

To assess changes in gastrointestinal function and patient-scored symptoms after Roux-en-Y gastric bypass (RYGB) and biliopancreatic diversion with duodenal switch (BPD/DS).

Setting

University hospital in Sweden.

Methods

We recruited 268 adult patients (mean age of 42.5 yr, body mass index 44.8, 67.9% female) listed for RYGB and BPD/DS. Patients answered validated questionnaires prospectively concerning bowel function, the Fecal Incontinence Quality of Life Scale, and the 36-Item Short Form Health Survey before and after their operation.

Results

Postoperatively, 208 patients (78.2% of 266 eligible patients) answered the questionnaires. RYGB patients had fewer bowel motions per week (8 versus 10) and more abdominal pain postoperatively (P<.001). Postoperatively, the 35 BPD/DS patients (69% versus 23%) needed to empty their bowel twice or more than twice daily, reported more flatus and urgency, and increased need for keeping a diet (P<.001). Concerning Fecal Incontinence Quality of Life Scale, coping and behavior was slightly reduced while depression and self-perception scores were improved after RYGB. Lifestyle, coping and behavior, and embarrassment were reduced after BPD/DS (P<.05). In the 36-Item Short Form Health Survey, physical scores were markedly improved, while mental scores were largely unaffected.

Conclusion

RYGB resulted in a reduced number of bowel movements but increased problems with abdominal pain. In contrast, BPD/DS-patients reported higher frequency of bowel movements, more troubles with flatus and urgency, and increased need for keeping a diet. These symptoms affected quality of life negatively, however, general quality of life was markedly improved after both procedures. These results will be of great value for preoperative counseling.  相似文献

Background

The National Bariatric Surgery Registry (NBSR) is the largest bespoke database in the field in the United Kingdom.

Objectives

Our aim was to analyze the NBSR to determine whether the effects of obesity surgery on associated co-morbidities observed in small randomized controlled clinical trials could be replicated in a "real life" setting within U.K. healthcare.

Setting

United Kingdom.

Methods

All NBSR entries for operations between 2000 and 2015 with associated demographic and co-morbidity data were analyzed retrospectively.

Results

A total of 50,782 entries were analyzed. The patients were predominantly female (78%) and white European with a mean age of 45 ± 11 years and a mean body mass index of 48 ± 8 kg/m2. Over 5 years of follow-up, statistically significant reductions in the prevalence of type 2 diabetes, hypertension, dyslipidemia, sleep apnea, asthma, functional impairment, arthritis, and gastroesophageal reflux disease were observed. The "remission" of these co-morbidities was evident 1 year postoperatively and reached a plateau 2 to 5 years after surgery. Obesity surgery was particularly effective on functional impairment and diabetes, almost doubling the proportion of patients able to climb 3 flights of stairs and halving the proportion of patients with diabetes related hyperglycemia compared with preoperatively. Surgery was safe with a morbidity of 3.1% and in-hospital mortality of .07% and a reduced median inpatient stay of 2 days, despite an increasingly sick patient population.

Conclusions

Obesity surgery in the U.K. results not only in weight loss, but also in substantial improvements in obesity-related co-morbidities. Appropriate support and funding will help improve the quality of the NBSR data set even further, thus enabling its use to inform healthcare policy.  相似文献

Background

We present our experience with same-day discharge (without an overnight stay) after laparoscopic sleeve gastrectomy (SG) in 821 consecutive patients from 2011 to 2015. This is the largest series published to date of patients undergoing ambulatory surgery for such a procedure.

Objectives

To review our outcomes from ambulatory SG over 52 months to determine if SG can be safely performed in the ambulatory setting.

Setting

Ambulatory surgery center.

Methods

Retrospective review of all consecutive patients undergoing ambulatory SG from January 2011 to April 2015. All patients were discharged home the same day after surgery without an overnight stay at the hospital. Incidence of complications and admission to the hospital after discharge was reviewed up to 30 days from surgery.

Results

From January 2011 to April 2015, 821 consecutive patients underwent SG. Nineteen 30-day complications occurred in the series, 17 of them requiring admission to the hospital. Of the 19 cases, gastric leaks accounted for 7, intr-aabdominal abscess for 4, and dehydration/nausea/vomiting for 4; 4 were due to other causes. Complication and readmission rates at 30 days were 2.3% and 2.1%, respectively. Follow-up at 30 days was 98.4%.

Conclusion

With stringent patient selection and utilization of enhanced recovery pathways, our study indicates that SG may be suitable for the outpatient setting. Experience and comfort with bariatric surgery is essential on the part of the operating surgeon to ensure good outcomes. Our low overall readmission and complication rate portends to the feasibility of laparoscopic SG as a safe outpatient procedure.  相似文献

Background

Low circulating magnesium concentrations predict cardiovascular and all-cause mortality in patients with type 2 diabetes (T2D). Epidemiologic and clinical studies have indicated lower extra- and intracellular magnesium concentrations in patients with diabetes.

Objective

We aimed to describe alterations, if any, in circulating magnesium concentrations after laparoscopic Roux-en-Y gastric bypass surgery (LRYGB) in patients with obesity and T2D.

Setting

Outpatient clinic of obesity and central hospital.

Methods

Retrospective analysis of 1-year outcome of plasma magnesium (p-Mg) and glucometabolic status in all consecutive patients who underwent primary LRYGBP and who completed the follow-up visits, including biochemical test panels 6 and 12 months after surgery.

Results

LRYGBP and complete follow-up visits were performed in 51 patients with T2D and 86 patients without T2D. All patients were given similar dietary advice and multivitamin and mineral supplementation after surgery. Before RYGB, the patients with T2D showed lower p-Mg compared with patients without T2D (.79 ± .06 mM and .82 ± .05 mM, respectively, P<.01). P-Mg was inversely correlated to fasting blood glucose and glycosylated hemoglobin levels. After surgery, mean p-Mg increased by 5.2% in the group with T2D compared with 1.4% in the patients without T2D (P<.01), ending at an equal level of .83 mM. The alterations in p-Mg were inversely related to the changes in fasting glucose and glycosylated hemoglobin concentrations.

Conclusion

The lowered p-Mg associated with impaired glucometabolic status in patients with T2D was increased after LRYGBP, reaching similar concentrations as in patients without T2D.  相似文献

Among carefully screened patients, bariatric surgery has proven safe and efficacious in the management of clinically severe obesity and poorly controlled type 2 diabetes. Nonetheless, individual outcomes vary, suggesting the need for interventions to maximize and sustain the health benefits of surgery. In this short review, we synthesize findings from the extant research literature to suggest the potential utility of a stepped care approach to optimize the postsurgery weight trajectory, which requires further research using adaptive designs. Starting with low-intensity, cost-effective interventions, such as self-weighing and self-monitoring, interventions that increase in intensity, such as counseling, meal replacements, or weight loss medications, could be added strategically according to predetermined decision rules based on patient weight change. Interventions could subsequently be withdrawn if no longer indicated, or reinstituted when appropriate, allowing for efficient allocation of resources in a personalized approach to postsurgery weight management over time.  相似文献

Background

Intragastric balloons (IGBs) are a minimally invasive option for obesity treatment, acting as a space-occupying device and leading to weight loss through increased satiety. This device has been growing in popularity owing to its safety profile and good weight loss results. However, there are no published guidelines that standardize the technical aspects of the procedure.

Objectives

To create a practical guideline for intragastric balloon usage.

Setting

Private and Academic Settings, Brazil.

Methods

A consensus meeting was held in São Paulo, Brazil, in June 2016, bringing together 39 Brazilian endoscopists with extensive experience in IGBs from all regions of the country. Topics on patient selection, indications, contraindications, multidisciplinary follow-up, technique, and adverse events were discussed in the form of questions. After electronic voting, a consensus was defined when there was ≥70% agreement. Experts were also requested to provide data on their experience with IGBs.

Results

The selected experts discussed and reached a consensus on 76 questions, mainly concerning specific indications and contraindications for the procedure; technical details, such as patient preparation, minimum balloon-filling volume, techniques for implant and explant; patient follow-up and recommended medication for the adaptation period; and adverse event management. The overall Brazilian expert data encompassed 41,863 IGBs, with a mean percentage total weight loss of 18.4% ± 2.9%. The adverse event rate after the adaptation period was 2.5%, the most common being hyperinflation (.9%) and spontaneous deflation (.8%) of the device. The early removal rate due to intolerance was 2.2%.

Conclusions

The present consensus represents practical recommendations for performing IGB procedures and reflects Brazil’s significant experience with this device. The experience of over 40,000 cases shows that the device leads to satisfactory weight loss with a low rate of adverse events.  相似文献

Although laparoscopic sleeve gastrectomy is an established operation for severe obesity, there is controversy regarding the extent to which the antrum is excised. The objective of this systematic review was to investigate the effect on perioperative complications and medium-term outcomes of antral resecting versus antral preserving sleeve gastrectomy. MEDLINE, EMBASE, and Cochrane databases were searched from 1946 to April 2017. Eligible studies compared antral resection (staple line commencing 2–3 cm from pylorus) with antral preservation (>5 cm from pylorus) in patients undergoing primary sleeve gastrectomy for obesity. Meta-analyses were performed with a random-effects model, and risk of bias within and across studies was assessed using validated scoring systems. Eight studies (619 participants) were included: 6 randomized controlled trials and 2 cohort studies. Overall follow-up was 94% for the specified outcomes of each study. Mean percentage excess weight loss was 62% at 12 months (7 studies; 574 patients) and 67% at 24 months (4 studies; 412 patients). Antral resection was associated with significant improvement in percentage excess weight loss at 24-month follow-up (mean 70% versus 61%; standardized mean difference .95; confidence interval .35–1.58, P<.005), an effect that remained significant when cohort studies were excluded. There was no difference in incidence of perioperative bleeding, leak, or de novo gastroesophageal reflux disease. According to the available evidence, antral resection is associated with better medium-term weight loss compared with antral preservation, without increased risk of surgical complications. Further randomized clinical trials are indicated to confirm this finding.  相似文献

Background

Numerous studies have established the effectiveness of Roux-en-Y gastric bypass (RYGB) for weight loss and co-morbidity amelioration. However, its safety and efficacy in elderly patients remains controversial.

Objectives

To evaluate outcomes in patients aged ≥60 years who underwent RYGB compared with nonsurgical controls with the hypothesis that RYGB provides weight loss benefits without differences in survival.

Setting

University-affiliated tertiary center.

Methods

All patients who underwent RYGB from 1985 to 2015 were identified and divided into elderly (age ≥60) and nonelderly (age <60) groups. A nonsurgical elderly control population was identified using a clinical data repository of outpatient visits to propensity match elderly patients 4:1 on demographic characteristics, co-morbidities, and relevant preoperative substance/medication use. Unpaired appropriate univariate analyses compared each stratified group. Kaplan-Meier survival curves were fitted based on social security death data.

Results

A total of 2306 patients underwent RYGB. The 107 elderly patients had lower median body mass index (47.0 versus 49.9; P?=?.007) and higher rates of co-morbidities. Rates of complications did not differ between elderly and nonelderly patients. Elderly surgical patients were propensity matched 4:1 (10,044 controls) yielding 428 well-matched nonsurgical controls. The elderly group demonstrated significant percent reduction in excess body mass index compared with the control group (81.8% versus 10.3%; P < .001). Kaplan-Meier survival analysis with log-rank test demonstrated no difference in midterm survival (P?=?.63).

Conclusions

A significant weight reduction benefit was identified after RYGB in elderly patients without a difference in midterm survival compared with propensity-matched controls, suggesting RYGB is a safe and efficacious weight loss strategy in the elderly.  相似文献

Background

There is an increased interest in understanding how variation in body composition (BC) and energy expenditure is related to successful weight loss after surgery. It has been suggested that low resting metabolic rate (RMR) could be associated with poor weight loss.

Objectives

To determine the relation among changes in BC, RMR, and weight loss after bariatric surgery.

Setting

University tertiary care hospital, Brazil.

Methods

A cohort of 45 patients submitted to bariatric surgery was prospectively studied. BC was evaluated by bioelectrical impedance analysis and RMR by indirect calorimetry before and 6 months after surgery. The RMR value was adjusted per kilogram of weight (RMR/kg). The patients were divided in 4 groups, based on patterns of change in the RMR/kg after surgery. The RMR/kg could decrease (group 1), remain stable (group 2), have a small increase (group 3), or have a major increase (group 4).

Results

A significant relation between fat-free mass and RMR for both pre- (P<.01) and postoperative periods (P<.01) was observed. Excess weight loss had a significantly correlation only with post-RMR/kg (P<.01). The pattern of change in RMR/kg was strongly correlated with weight loss, considering an excess weight loss>50% a successful weight loss: No patients achieved success in group 1; 61% of patients did in group 2; 80% di in group 3; and all patients in group 4 had successful weight loss.

Conclusions

We demonstrate a clearly correlation between the postoperative RMR and weight loss. The increase in RMR/kg after surgery is a major factor related to a satisfactory excess weight loss after surgery.  相似文献
