Background
Many insurance companies require patient participation in a medically supervised weight management program (WMP) before offering approval for bariatric surgery. Clinical data surrounding benefits of participation are limited.Objective
To evaluate the relationship between preoperative insurance-mandated WMP participation and postoperative outcomes in bariatric surgery patients.Setting
Regional referral center and teaching hospital.Methods
A retrospective review of patients who underwent vertical sleeve gastrectomy or Roux-en-Y gastric bypass between January 2014 and January 2016 was performed. Patients (N = 354) were divided into 2 cohorts and analyzed according to presence (n = 266) or absence (n = 88) of an insurance-mandated WMP requirement. Primary endpoints included rate of follow-up and percent of excess weight loss (%EWL) at postoperative months 1, 3, 6, and 12. All patients, regardless of the insurance-mandated WMP requirement, followed a program-directed preoperative diet.Results
The majority of patients with an insurance-mandated WMP requirement had private insurance (63.9%). Both patient groups experienced a similar proportion of readmissions and reoperations, rate of follow-up, and %EWL at 1, 3, 6, and 12 months (P = NS). Median operative duration and hospital length of stay were also similar between groups. Linear regression analysis revealed no significant improvement in %EWL at 12 months in the yes-WMP group.Conclusion
These data show that patients who participate in an insurance-mandated WMP in addition to completing a program-directed preoperative diet experience no significant benefit to rate of readmission, reoperation, follow-up, or %EWL up to 12 months postoperation. Our findings suggest that undergoing bariatric surgery without completing an insurance-mandated WMP is safe and effective. 相似文献2.

BackgroundLong-term (>5 yr) studies assessing outcomes after laparoscopic Roux-en-Y gastric bypass (LRYGB) using the Bariatric Analysis and Reporting Outcome System (BAROS) are limited. Evidence of predictors of failure long-term after LRYGB is also lacking.ObjectivesTo compare BAROS scores at 5 and 10 years post LRYGB and to establish whether individual obesity-related co-morbidities are associated with suboptimal outcomes at these time points.SettingSingle bariatric unit.MethodsBAROS scores were analyzed in patients who were 5 years (group A) and 10 years (group B) post LRYGB. Obesity-related co-morbidities as predictors of failure of surgery (defined by % excess weight loss [%EWL] <50% or BAROS total score ≤1) were examined. Intergroup comparative analysis of outcomes and logistic regression modeling to determine predictors of weight loss failure were conducted.ResultsA total of 88 patients were 5 years post LRYGB (group A), and 91 patients were 10 years post LRYGB (group B). A total of 52.3% (46/88) in group A and 54.9% (50/91) in group B had failure of weight loss defined by %EWL <50%. There were no significant differences in percentage of total weight loss, %EWL, or BAROS scores between the 2 groups (21.8% versus 22.0%, P = .897; 48.5% versus 47.1%, P = .993; and 3.7 versus 3.3, P = .332, respectively). No individual obesity-related co-morbidity at time of surgery was associated with suboptimal outcomes (%EWL <50% or BAROS total score ≤1) at 5 years or 10 years after LRYGB.ConclusionsLong-term outcomes assessed by the BAROS score appear sustainable between 5 and 10 years after LRYGB surgery, and weight loss achieved at 5 years is maintained at 10 years. Preoperative presence of specific obesity-related co-morbidities was not associated with failure of surgery long-term. 相似文献

BackgroundFindings regarding longer term symptoms of depression and the impact of depression on outcomes such as weight loss and patient satisfaction, are mixed or lacking.ObjectivesThis study sought to understand the relationship between depression, weight loss, and patient satisfaction in the two years after bariatric surgery.SettingThis study used data from a multi-institutional, statewide quality improvement collaborative of 45 different bariatric surgery sites.MethodsParticipants included patients (N = 1991) who underwent Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG) between 2015–2018. Participants self-reported symptoms of depression (Patient Health Questionnaire-8 [PHQ-8]), satisfaction with surgery, and weight presurgery and 1 year and 2 years postsurgery.ResultsCompared to presurgery, fewer patients’ PHQ-8 scores indicated clinically significant depression (PHQ-8≥10) at 1 year (P < .001; 14.3% versus 5.1%) and 2 years postsurgery (P < .0001; 8.7%). There was a significant increase in the prevalence of clinical depression from the first to second year postsurgery (P < .0001; 5.1% versus 8.7%). Higher PHQ-8 at baseline was related to less weight loss (%Total Weight Loss [%TWL] and %Excess Weight Loss [%EWL]) at 1 year postsurgery (P < .001), with a trend toward statistical significance at 2 years (P = .06). Postoperative depression was related to lower %TWL and %EWL, and less reduction in body mass index (BMI) at 1 year (P < .001) and 2 years (P < .0001). Baseline and postoperative depression were associated with lower patient satisfaction at both postoperative time points.ConclusionsThis study suggests improvements in depression up to 2 years postbariatric surgery, although it appears that the prevalence of depression increases after the first year. Depression, both pre- and postbariatric surgery, may impact weight loss and patient satisfaction. 相似文献

Background
Sarwer et al. found that poor dietary adherence at 6 months postoperatively predicted lower weight loss.Objectives
To replicate and extend these findings.Setting
University bariatric clinic.Methods
Fifty-four adults (72% female; age 51.1 ± 11.3 yr; mean body mass index [BMI]?=?43.8 ± 7.4 kg/m2; 53.7%?=?Roux-en-Y gastric bypass, 42.6%?=?laparoscopic sleeve gastrectomy, and 3.7%?=?gastric banding) were identified as low or high dietary adherers following the method of Sarwer et al. Patients self-reported dietary adherence with a 9-point Likert scale. Splitting the group at the median, low adherers scored <7 and high dietary adherers ≥7. BMI, percentage excess weight loss (%EWL), and percentage total weight loss (%TWL) were prospectively assessed at 12, 24, and 36 months. Two-tailed independent t tests and Cohen's d effect sizes were used to compare between-group outcomes.Results
BMI did not differ between low (n?=?24) and high (n?=?30) dietary adherers at 6 months after surgery. At 12 months, the BMI of low (n?=?17) adheres was significantly higher (34.1 ± 4.61 versus 30.3 ± 3.90 kg/m2, P?=?.006, d?=?0.90) than that of high (n?=?25) adherers, with significantly less %EWL (49.0 ± 24% versus 70.7 ± 21.5%; P?=?.004; d?=?0.95) and %TWL (20.7 ± 11.5% versus 28.9 ± 10.5, P?=?.02, d = 0.74). At 24 months, BMI remained significantly higher for low (n?=?12) versus high (n?=?10) adherers (33.7 ± 4.77 versus 29.7 ± 3.82 kg/m2, P?=?.045, d?=?0.92), but %EWL and %TWL were not significantly different, despite large effect sizes. At 36 months, moderate effects supported continued higher BMIs and lower %EWL and %TWL for low (n?=?5) versus high (n?=?8) adherers. Attrition from follow-up was 22.2% (12 mo), 59.3% (24 mo), and 75.9% (36 mo). Post hoc analyses revealed no impact of baseline characteristics on low follow-up rates except younger age (at 1 yr).Conclusions
Findings that 6-month postoperative dietary adherence predicts 12-month BMI, %EWL, and %TWL were replicated. Medium to large effects suggest findings extend to 24 and 36 months, with low follow-up rates likely affecting statistical significance. 相似文献5.

BackgroundMany insurance companies have mandated that bariatric surgery candidates already satisfying the National Institutes of Health criteria make an additional attempt at medically supervised weight loss. The objective of this study was to determine whether a correlation exists between the number of weight loss attempts (WLAs) or maximal preoperative weight loss (MWL) and the percentage of excess weight loss (%EWL) after laparoscopic Roux-en-Y gastric bypass (LRYGB) surgery.MethodsThe WLAs and MWL data were collected by bariatric medical record review. The postoperative %EWL was obtained by retrospective review of a prospectively enrolled bariatric database. Patients whose records contained 1 year of follow-up data and either the WLAs or MWL were included in the study. The data were analyzed using Pearson correlations and odds ratios.ResultsFrom September 2001 to 2006, 530 patients underwent LRYGB. Of these, 384 met the study criteria (82.6% were women). The mean WLAs was 4.3 ± 1.8. The mean MWL was 46.6 ± 31.2 lb (21.2 ± 14.2 kg). At surgery, the mean patient age was 43.3 ± 9.3 years, and the mean body mass index was 48.0 ± 5.9 kg/m2. At 1 year after LRYGB, the mean body mass index was 30.2 ± 5.0 kg/m2, and the mean %EWL was 72.3% ± 15.3%. Statistical analysis revealed no correlations between the %EWL at 1 year after LRYGB and the WLAs (R2 = .011) or MWL (R2 = .005).ConclusionNeither the WLAs nor the MWL correlated with the %EWL at 1 year after LRYGB. Our results showed no evidence that the WLAs or MWL before surgery correlates with the %EWL in patients undergoing LRYGB. 相似文献

BackgroundSleeve gastrectomy (SG) is the most common surgery for severe obesity. Patients lose weight post SG and regain some weight in the following years. Early weight loss predicts weight loss after SG. However, etiologies of weight loss and regain after SG remain unclear.ObjectivesTo investigate the effects of early weight loss on medium-term weight regain post SG.SettingTwo university hospitals in Taiwan.MethodsPatients with records within 1 and at 3 years after SG were enrolled retrospectively. Preoperative clinical variables and percentage of total weight loss (%TWL) were analyzed. Weight regain was defined as a weight increase from 1 year postoperatively of >25% of the lost weight. Linear and multiple logistic regression were applied to examine the associations of early weight loss, weight loss, and weight regain.ResultsA total of 363 patients were included. Body mass indexes before and 1, 3, 6, 12, and 36 months postoperatively were 40.7 ± 6.8 kg/m2, 36.6 ± 6.2 kg/m2, 33.5 ± 5.8 kg/m2, 30.9 ± 5.5 kg/m2, 28.4 ± 5.2, and 29.3 ± 5.4 kg/m2, respectively. At 3 years after SG, 73 patients (20.1%) had weight regain. In multivariate linear analyses, initial age, waist circumference, type 2 diabetes, and %TWL at 1 or 3 months were associated with either 1-year or 3-year %TWL. Multiple logistic regression revealed %TWL at 3 months to be a predictor for 3-year weight regain after SG (odds ratio, .927; P = .02).ConclusionEarly weight loss predicted weight loss and regain 3 years after SG. Early lifestyle and behavioral interventions are suggested in patients at high risk of poor weight loss and weight regain outcomes after SG. 相似文献

BackgroundLaparoscopic sleeve gastrectomy (LSG) has become a popular surgical procedure among bariatric surgeons. Few studies have compared the efficacy of the procedure to laparoscopic Roux-en-Y gastric bypass (LRYGB). We performed a case-control study to assess the surgical results, weight progression, and remission of co-morbid conditions.MethodsFrom January 2006 to September 2009, we selected 811 patients undergoing LSG as a primary procedure. These patients were matched by age, body mass index, and gender to 786 patients undergoing LRYGB. The complication rate, mortality, and percentage of excess weight loss after 1, 2, and 3 years were analyzed.ResultsThe mean age for the LRYGB and LSG groups was 37.0 ± 10.3 and 36.4 ± 11.7 years, respectively (P = .120). Most of the patients were women (LRYGB 76.6% versus LSG 76.2%; P = .855). The preoperative body mass index before surgery was similar in both groups (LRYGB 38.0 ± 3.2 versus LSG 37.9 ± 4.6 kg/m2; P = .617). The mean operative time was longer for LRYGB (106.2 ± 33.2 versus 76.6 ± 28.0 min; P <.001), and the hospital stay was longer for LRYGB (3.4 ± 4.4 versus 2.8 ± .8 for LSG; P <.001). The early complication rate was 7.1% for LRYGB and 2.9% for LSG (P <.001), and the suture leak rate was .7% for LRYGB and .5% for LSG (P = NS). The percentage of excess weight loss for LRYGB versus LSG at 1, 2, and 3 years was 97.2% ± 24.3% versus 86.4% ± 26.4% (P <.001), 94.6% ± 30.2% versus 84.1% ± 28.3% (P <.001), and 93.1% ± 25.0% versus 86.8% ± 27.1% (P = .082), respectively. The total cholesterol level at 1 year for LRYGB versus LSG was 169.0 ± 32.9 versus 193.6 ± 38.7 mg/dL, respectively (P <.001), and the rate of diabetes remission was similar in both groups (LRYGB 86.6% versus LSG 90.9%).ConclusionLSG has become an acceptable primary bariatric procedure for obesity, with results comparable to LRYGB in this population. 相似文献

Objective
To evaluate the weight loss outcomes of banded Roux-en-Y gastric bypass (RYGB) during a 10-year follow-up.Setting
Private health-providing service, Brazil.Methods
A prospective study was conducted on 928 patients with obesity who underwent banded RYGB. Patients were divided into 2 groups according to their initial body mass index (BMI), morbid obesity (BMI 35–49.9 kg/m2) and super obesity (BMI ≥50 kg/m2). The percentages of excess weight loss (%EWL) and total weight loss (%TWL) at 18, 24, 36, 48, 60, 72, 84, 96, 108, and 120 months after surgery were assessed and compared, and the rates of surgical failure were also assessed.Results
There were individuals who were lost to follow-up at each year, including 423 (45.6%) at 18 months, 431 (46.4%) at 24 months, 482 (51.9%) at 36 months, 568 (61.2%) at 48 months, 658 (70.9%) at 60 months, 725 (78.1%) at 72 months, 781 (84.2%) at 84 months, 819 (88.3%) at 96 months, 838 (90.3%) at 108 months, and 819 (88.3%) at 120 months. The maximal %EWL was achieved at 18 months (P<.001). After 10 years, there was no significant change in mean BMI (28.7 ± 4.1 versus 28.5 ± 3.6 kg/m2; P = .07) or %EWL (80.4 ± 19.1 versus 79.7 ± 23.4; P = .065), but the mean %TWL was significantly lower at 10 years (30.8 ± 8.5 versus 32.5 ± 8.1; P = .035) in the morbid obesity group, compared with the values observed over 5 years. In the super obesity group, the %EWL significantly decreased from 77.7 ± 16.5 kg/m2 at 24 months to 71.3 ± 18.1 kg/m2 at 72 months (P = .008); at 5 years, mean BMI (33.1 ± 5.8 kg/m2) did not differ from the one observed at 10 years (36.4 ± 5 kg/m2; P = .21), as well as the mean %TWL (40.1 ± 8.5 versus 34.8 ± 8.9; P = .334).Conclusion
Banded RYGB leads to significant and sustained weight loss in a 10-year follow-up. Despite a slight late weight regain evaluated by %TWL, RYGB leads to an optimal weight loss in the majority of the individuals. 相似文献10.

BackgroundExisting research demonstrates that parity is associated with risk for obesity. The majority of those who undergo bariatric surgery are women, yet little is known about whether having children before bariatric surgery is associated with pre- and postsurgical weight outcomes.ObjectivesWe aim to evaluate presurgical body mass index (BMI) and postsurgical weight loss among a racially diverse sample of women with and without children.SettingMetropolitan hospital system.MethodsWomen (n = 246) who underwent bariatric surgery were included in this study. Participants self-reported their number of children. Presurgical BMI and postsurgical weight outcomes at 1 year, including change in BMI (ΔBMI), percentage excess weight loss (%EWL), and percentage total weight loss (%TWL) were calculated from measured height and weight.ResultsThose with children had a lower presurgical BMI (P = .01) and had a smaller ΔBMI (P = .01) at 1 year after surgery than those without children, although %EWL and %TWL at 1 year did not differ by child status or number of children. After controlling for age, race, and surgery type, the number of children a woman had was related to smaller ΔBMI at 1 year post surgery (P = .01).ConclusionsAlthough women with children had lower reductions in BMI than those without children, both women with and without children achieved successful postsurgical weight loss. Providers should assess for number of children and be cautious not to deter women with children from having bariatric surgery. 相似文献

BackgroundLaparoscopic Roux-en-Y gastric bypass (LRYGB) is the most effective treatment for morbid obesity. The additional benefit of placing a nonadjustable band around the pouch remains to be determined. The objective of this study was to compare outcomes between banded and nonbanded LRYGB patients in a single bariatric center.MethodsA matched cohort analysis was performed between patients who had undergone banded and nonbanded (standard) LRYGB. In the banded bypass cohort, an 8 F, 6.5 cm silastic ring was placed around the proximal gastric pouch. Both cohorts were matched for age, body mass index (BMI), and anastomotic technique. Endpoints included percentage excess weight loss (%EWL), postoperative morbidity, and band-related complications.ResultsBetween January 2007 and July 2010, 134 banded LRYGB were performed (55% female, mean age 45 years). They were compared with a matched cohort of 134 concurrent nonbanded LRYGB patients (67% female, mean age 45.4 years). Mean preoperative BMI was 54.6 and 52.8 kg/m2, respectively (P = .084). At 24 months postoperatively, the average %EWL was 58.6% in banded bypass patients and 51.4% in the nonbanded group (P = .015). The difference in EWL was more pronounced in super-obese patients than in those with BMI<50 (among super-obese, 57.5% versus 47.6%, P = .003; among those with BMI<50, 62.9% versus 57.9%, P = .406]. There was no difference in early (19.4% versus 19.4%) or late complications (10.4% versus 13.4%, P = .451) between banded and nonbanded LRYGB patients.ConclusionBanding the pouch during LRYGB can be performed safely and may provide better weight loss, particularly in super-obese patients. Further prospective and long-term comparative studies of this technique are warranted. 相似文献

BackgroundLaparoscopic sleeve gastrectomy (LSG) is gaining acceptance in the bariatric community as a definitive weight loss procedure; however, longitudinal data remain limited. The objective of this study was to compare weight loss results of LSG with laparoscopic Roux-en-Y gastric bypass (LRYGB) up to 5 years postoperatively using anthropometric measurements.MethodsProspectively collected bariatric database at the Naval Medical Center San Diego was retrospectively reviewed from 2005–2011 . Anthropometric factors, including weight and hip circumference were measured during standard yearly follow-up appointments. Surgical outcomes were tested by the Student t test and demographic variables by Fisher’s exact and Wilcoxon rank-sum tests.ResultsFollow-up was achieved in 147/226 LRYGB versus 130/208 LSG at year 1, 92/195 versus 81/151 at year 2, 64/145 versus 50/100 at year 3, 32/81 versus 18/54 at year 4, and 12/42 versus 14/15 at year 5. The excess weight loss (EWL) for LRYGB versus LSG was 72% versus 64.7% at 1 year (P = .002), 71.3% versus 65.5% at 2 years (P = .113), and 68.3% versus 57.4% at 5 years (P = .252), respectively. Similarly, the body mass index (BMI) decrease was statistically significant at 1 year (P = .001) but not on subsequent annual visits. Mean percent body adiposity index (BAI) decrease was 28.4% for LRYGB versus 26.8% for LSG at 1 year (P = .679) and 21.8% versus 29.8% at 2 years (P = .134), respectively. Weight loss measured in terms of %EWL and decrease in BMI and BAI did not show significance between LRYGB and LSG 2 years after surgery.ConclusionOur study provides similar long-term weight loss between LSG and LRYGB, and therefore, LSG is a viable option as a definitive bariatric procedure. 相似文献

BackgroundBariatric surgery is currently the most effective long-term treatment for severe obesity. However, interindividual variation in surgery outcome has been observed, and research suggests a moderating effect of several factors including baseline co-morbidities (e.g., type 2 diabetes [T2D] and genetic factors). No data are currently available on the interaction between T2D and variants in brain derived neurotrophic factor (BDNF) and its effect on weight loss after surgery.ObjectivesTo examine the role of the BDNF Val66Met polymorphism (rs6265) and the influence of T2D and their interaction on weight loss after bariatric surgery in a cohort of patients with severe obesity.SettingUniversity hospital in Spain.MethodsThe present study evaluated a cohort of 158 patients with obesity submitted to bariatric surgery (Roux-en-Y gastric bypass or sleeve gastrectomy) followed up for 24 months (loss to follow-up: 0%). During the postoperative period, percentage of excess body mass index loss (%EBMIL), percentage of excess weight loss (%EWL), and total weight loss (%TWL) were evaluated.ResultsLongitudinal analyses showed a suggestive effect of BDNF genotype on the %EWL (P = .056) and indicated that individuals carrying the methionine (Met) allele may experience a better outcome after bariatric surgery than those with the valine/valine (Val/Val) genotype. We found a negative effect of a T2D diagnosis at baseline on %EBMIL (P = .004). Additionally, we found an interaction between BDNF genotype and T2D on %EWL and %EBMIL (P = .027 and P = .0004, respectively), whereby individuals with the Met allele without T2D displayed a greater %EWL and greater %EBMIL at 12 months and 24 months than their counterparts with T2D or patients with the Val/Val genotype with or without T2D.ConclusionOur data showed an association between the Met variant and greater weight loss after bariatric surgery in patients without T2D. The presence of T2D seems to counteract this positive effect. 相似文献

Background
Sleeve gastrectomy (SG) has grown into the most popular bariatric operation. Nevertheless, a scarcity of long-term outcomes are available.Objectives
This study aims at evaluating the long-term percent weight loss (%WL), excess weight loss (%EWL), weight regain (WR), and co-morbidity resolution rates in a single-center cohort undergoing SG as a primary procedure, with a minimum 10-year follow-up.Setting
University hospital, Italy.Methods
One hundred eighty-two morbidly obese patients with body mass index (BMI) 46.6 ± 7.3 kg/m2 underwent SG. Obesity-related co-morbidities (type 2 diabetes, hypertension, sleep apnea, gastroesophageal reflux disease) were investigated. Predictors of dichotomous dependent-variable diabetes remission were computed using a binomial logistic regression.Results
Patient retention rate was 77%. Mean %WL was 30.9, %EWL was 52.5%, and WR (≥25% maximum WL) occurred in 10.4%. Baseline BMI significantly (P?=?.001) and linearly predicted %EWL (10 yr %EWL?=?18.951?+?initial BMI × .74); the super-obese subgroup generated substantially greater WL compared with those with BMI <50 kg/m2 (%EWL 48.0 ± 18.5 versus 61.5 ± 23.2; P < .001). Type 2 diabetes remission occurred in 64.7%; 42.9% patients developed de novo gastroesophageal reflux disease symptoms postoperatively (P < .0001).Conclusions
SG generates sustained WL and co-morbidity resolution up to 10 years postoperatively. Although a notable portion of patients experience WR, mean %WL persists to exceed 30%, translating in adequate WL also in the long term. Additionally, WR does not seem to impact negatively on co-morbidity resolution. SG represents a safe and effective bariatric operation, which easily grants the possibility to proceed to revisional bariatric surgery in patients with WR or failure to WL. 相似文献15.

BackgroundIn the Netherlands, patients only qualify for bariatric surgery when they have followed a 6-month mandatory weight loss program (MWP), also called the “last resort” criterion. One of the rationales for this is that MWPs result in greater weight loss.ObjectivesTo determine weight loss during MWPs and the effect of delayed versus immediate qualification on weight loss 3 years after bariatric surgery.SettingOutpatient clinic.MethodsThis is a nationwide, retrospective study with prospectively collected data. All patients who underwent a primary bariatric procedure in 2016 were included. We compared weight loss between patients who did not qualify according to the last resort criterion at screening (delayed group) with patients that qualified (immediate group).ResultsIn total 2628 patients were included. Mean age was 44.4 years, 81.3% were female, and baseline BMI was 42.3 kg/m2. Roux-en-Y gastric bypass (RYGB) was the most frequently performed surgery (77.0%), followed by sleeve gastrectomy (15.8%) and banded RYGB (7.3%). The delayed group (n = 831; 32%) compared with immediate group (n = 1797; 68%), showed less percentage of total weight loss (%TWL) during the MWP (1.7% versus 3.9%, P < .001) and time between screening and surgery was longer (42.3 versus 17.5 wk, P < .001). Linear mixed model analysis showed no significant difference in %TWL at 18- (P = .291, n = 2077), 24- (P = .580, n = 1993) and 36-month (P = .325, n = 1743) follow-up.ConclusionThis study shows that delayed qualification for bariatric surgery compared with immediate qualification does not have a clinically relevant impact on postoperative weight loss 3 years after bariatric surgery. 相似文献

BackgroundRapid weight loss after bariatric surgery has been a factor of inducing gallstones postoperatively. Many studies have reported increased gallstone formation after laparoscopic Roux-en-Y gastric bypass (LRYGB). However, not many studies have compared symptomatic gallstone frequencies between LRYGB, laparoscopic sleeve gastrectomy (LSG), and laparoscopic adjustable gastric banding (LAGB). The aim of our study is to evaluate symptomatic cholelithiasis cases requiring cholecystectomy after each bariatric procedure.MethodsBetween January 2009 and August 2011, a total of 937 patients underwent bariatric surgery at our institution. Of these patients, 598 had primary LRYGB, 197 had LSG, and 142 had LAGB. We excluded patients with previous cholecystectomy or concomitant cholecystectomy at the time of bariatric procedure. A retrospective review of a prospectively collected database was performed for all patients.ResultsOf 367 LRYGB patients, 5.7% (n = 21) had symptomatic gallstones. Of 115 LSG patients, 6.1% (n = 7) required cholecystectomy, and of 104 LAGB patients, .0% (n = 0) developed symptomatic gallstones. The differences in the occurrences of symptomatic gallstones between LRYGB and LSG were not statistically significant (P>.88). However, statistical significance was present between LRYGB and LAGB (P<.02), as well as between LSG and LAGB (P<.02). Mean percentage of excess weight loss (%EWL) at 24 months was 85.7%, 58.8%, and 38.3% in LRYGB, LSG, and LAGB patients, respectively. There was no complication related to the cholecystectomy procedure.ConclusionsFrequency of symptomatic gallstones after LRYGB and LSG was not significantly different and after LAGB was significantly lower. Slow and less amount of weight loss would have contributed to the low rate of symptomatic gallstone formation in the LAGB patients.

BackgroundObesity has become a global problem that poses a serious threat to human health. Laparoscopic sleeve gastrectomy (LSG) is an effective long-term treatment. However, the weight loss of some patients after LSG is still insufficient. It is necessary to investigate the factors associated with inadequate weight loss after LSG.ObjectiveThe objective of this study was to explore whether preoperative insulin secretion could be associated with weight loss after LSG in patients with obesity.SettingThis is a single-center prospective cohort study conducted in a university hospital.MethodsPatients from a prospective database who underwent LSG were analyzed. All 178 participants underwent a 75-g oral glucose tolerance test (OGTT) to assess preoperative insulin and c-peptide secretion before LSG. The areas under the curve (AUCs) for glucose, insulin, and c-peptide were determined in the OGTT. The percentage of excess weight loss (%EWL) and the percentage of total weight loss (%TWL) were used to estimate the effect of weight loss after LSG. Regression models were used to assess the correlation between preoperative insulin and c-peptide secretion with %EWL ≥75% and TWL ≥35% at 12 months after LSG.ResultsThe AUCs of insulin and c-peptide were significantly lower in the %EWL ≥75% and %TWL ≥35% groups at 0–30 minutes, 0–60 minutes, and 0–120 minutes during the OGTT. At 30, 60, and 120 minutes during the OGTT, c-peptide levels were significantly lower in the %EWL ≥75% group and %TWL ≥35% group. The preoperative c-peptide level at 30 minutes during the OGTT (C30) was significantly negatively correlated with %EWL (β = ?.37, P < .001) and %TWL (β = ?.28, P = .011). Univariate logistic regression analysis showed that preoperative C30 was associated with %EWL ≥75% and %TWL ≥35% after LSG. According to multiple logistic regression analysis, patients with a low preoperative C30 had an 8-fold higher %TWL ≥35% after LSG than those with a high C30 (odds ratio: 8.41 [95% confidence interval: 1.46–48.58], P = .017). Similarly, patients with a low preoperative C30 had a 7-fold higher EWL% ≥75% after LSG than patients with a high C30 (odds ratio: 7.25 [95% confidence interval: 1.11–47.50], P = .039).ConclusionsThe rate of weight loss after LSG is low among patients with preoperative hyperinsulinemia. The preoperative c-peptide level at 30 minutes during the OGTT is associated with weight loss after LSG. 相似文献

Background
Current methods for weight loss assessment after bariatric surgery do not meet the high standards required to accurately judge patient outcome in a fair and evidence-based way.Objectives
To build an evidence-based, versatile tool to assess weight loss and weight regain and identify poor responders up to 7 years after laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG), for any preoperative body mass index (BMI).Setting
Multicenter, observational study.Methods
Bariatric weight loss charts were built with standard deviation (SD) percentile (p) curves p+2SD/p+1SD/p50(median)/p?1SD/p?2SD, based on all last measured weight results after primary LRYGB and LSG, performed in 3 large bariatric centers, expressed with percentage total weight loss (%TWL) and percentage-alterable weight loss (%AWL), a special BMI-independent metric. The p?1SD %AWL curves were compared with popular bariatric criteria 50% excess weight loss and 20%TWL. The p50 %TWL curves were compared with %TWL outcome in literature (external validation).Results
In total, 9393 patients (5516 LRYGB, 3877 LSG, baseline BMI 43.7 (±SD 5.3) kg/m2, age 43 (±SD 10.9) years, 20% male, 21% type 2 diabetes) had mean follow-up 26 (range, 0–109) months, with .09% 30-day mortality. Independent outcome is presented in percentile charts for %AWL and %TWL. Percentile curves p+2SD/p+1SD/p50/p?1SD/p?2SD showed for LRYGB 72%/62%/50%/38%/28%AWL at nadir, 66%/55%/43%/30%/17%AWL at 4 years, 64%/52%/38%/25%/11%AWL at 7 years, and for LSG 69%/58%/46%/34%/22%AWL, 65%/53%/38%/23%/12%AWL, and 63%/51%/35%/22%/9%AWL, respectively. Bariatric criteria 50% excess weight loss and 20%TWL matched with most insufficient results for LSG, but not for LRYGB (low specificities). Both p50 %TWL curves are comparable with long-term weight loss in bariatric literature.Conclusions
Just as well-known growth charts are essential for pediatrics, weight loss charts should become the tools of choice for bariatrics. These multicenter charts are baseline BMI independent, superior to current bariatric criteria, and quite intuitive to use. They allow to readily detect poor responders in any postoperative phase, monitor the effect of extra counseling, judge weight regain, and manage patient expectations. 相似文献19.

BackgroundLaparoscopic sleeve gastrectomy (SG) achieves excellent weight loss, yet recent reports indicate weight regain in a substantial number of patients.ObjectivesInserting a nonadjustable gastric band may improve weight loss after SG.SettingUniversity Hospital, Germany.MethodsIn a retrospective matched-pair analysis 51 patients who underwent banded SG (BSG) using a silicone ring between November 2010 and May 2017 were compared with patients who underwent conventional SG regarding weight loss, complications, and co-morbidity. Median follow-up was 5 years.ResultsTotal weight loss was equal in the early follow-up (P = .118 and P = .111) but significantly better in BSG 3 and 5 years after surgery (BSG versus SG at 3 yr 38.7% ± 7.8, n = 33 versus 31.9 ± 10.7, n = 33, P = .002; BSG versus SG at 5 yr 37.6% ± 8.5, n = 27 versus 29.5 ± 12.9, n = 23, P = .008). Ring placement had no significant impact on clinical reflux signs (Fisher's exact test P > .999), yet 37 % of BSG patients reported ≥1 regurgitation per week (Fisher's exact test P = .013, odds ratio 12.4).ConclusionBSG leads to better weight loss than nonbanded SG 5 years after surgery. This comes at the expense of a higher rate of regurgitation. At a time in which weight loss limitations of a stand-alone SG are becoming a clinical problem, banding the sleeve may be a strategy to improve weight loss with this procedure. 相似文献

BackgroundInsufficient weight loss or secondary weight regain with or without recurrence of comorbidity can occur years after laparoscopic Roux en Y gastric bypass (LRYGB). In selected patients, increasing restriction or adding malabsorption may be a surgical option after conservative measures failed.ObjectivesEvaluation of short and long term results of revisional surgery for insufficient weight loss or weight regain after LRYGB.SettingTertiary hospital.MethodsRetrospective analysis of prospectively collected data from a cohort of 1150 LRYGB patients. Included were patients, who underwent revisional bariatric surgery after LRYGB for insufficient weight loss with a follow-up of minimal 1 year.ResultsFifty-four patients were included in the analysis. After an interdisciplinary evaluation, patients with insufficient weight loss, signs of dumping syndrome, and lacking restriction were offered a nonadjustable band around the pouch (banded group, n = 34) and patients with sufficient restriction, excellent compliance, and adherence were offered a revision to laparoscopic biliopancreatic diversion (BPD group, n = 20). The revisional procedure was performed 3.3 ± 2.3 years after LRYGB in the banded-group and after 6.4 ± 4.3 years in the BPD group (P = .001). Mean body mass index at the time of the primary bariatric procedure was 41.7 ± 6.2 kg/m2 in the banded group and 45.2 ± 8.2 kg/m2 in the BPD group (P = .08); minimal body mass index between both operations was 29.1 ± 4.7 kg/m2 in the banded group and 36.5 ± 9.4 kg/m2 in the BPD group, and, at the time of revisional surgery, 31.4 ± 5.5 kg/m2 in the banded group and 40.8 ± 6.7 kg/m2 in the BPD group (P = .0001). The mean body mass index difference 1 year after revisional surgery was 1.3 ± 3.0 kg/m2 in the banded group and 6.7 ± 4.5 kg/m2 in the BPD group (P = .01). In the banded group, 11 patients (32.4%) needed removal of the band, 4 patients (11.8%) needed an adjustment, and 4 patients (11.8%) were later converted to BPD. In the BPD group, 2 (10.0%) patients needed revision for severe protein malabsorption.ConclusionsInsufficient weight loss or secondary weight regain after LRYGB is a rare indication for revisional surgery. Banded bypass has modest results for additional weight loss but can help patients suffering from dumping. In very carefully selected cases, BPD can achieve additional weight loss with acceptable complication rate but higher risk for reoperation. Future “adjuvant medical treatments,” such as glucagon-like peptide 1 analogues and other pharmacologic treatment options could be an alternative for achieving additional weight loss and better metabolic response. 相似文献
