Bariatric surgery has emerged as an important tool in the fight against morbid obesity. However, reviewers have noted that
there is a scarcity of long-term clinical surveillance data for bariatric surgery beyond 1-year follow-up and that a high
percentage of patients are lost to follow-up, raising questions regarding the accuracy of current outcomes estimates. A meta-analysis
of clinical reports providing bariatric surgery weight loss outcomes for morbidly obese patients was conducted over the period
2003–2007. Studies included were randomized controlled trials, nonrandomized controlled trials, and consecutive case series
involving patients receiving either laparoscopic adjustable gastric banding (LAGB) or laparoscopic gastric bypass (LGB) surgery.
Included studies involved n = 7,383 patients and were largely academic hospital-based (78.6%) and retrospective in design (71.4%). Weight loss outcome
was defined by percent excess weight loss (%EWL). Composite estimates showed a significantly greater %EWL for LGB surgery
(62.6%) compared to LAGB (49.4%). The superiority of LGB persisted at all three postsurgical time points examined (1, 2, and
>3 years). Problems were identified regarding incomplete or suboptimal data reporting in many studies reviewed, and high patient
attrition was evident at 2-year (49.8% LAGB, 75.2% LGB) and >3-year (82.6% LAGB, 89% LGB) end points. This meta-analysis confirms
the superiority of LGB to LAGB in %EWL found in earlier studies. Although problems in study quality raised significant concerns
regarding the validity of current weight loss estimates in this area, there was no evidence of publication bias. 相似文献

BackgroundThe evidence regarding the effectiveness and safety of laparoscopic sleeve gastrectomy (LSG) has been mostly based on the data derived from nonrandomized studies. The objective of this study was to evaluate the outcomes of LSG and to present an up-to-date review of the available evidence based on the recent publications of new randomized, controlled trials (RCTs).MethodsPubMed, Embase, and Cochrane Central Register of Controlled Trials were searched until November 2012 for RCTs on LSG.ResultsFifteen RCTs, comprising a total of 1191 patients, of whom 795 had undergone LSG, were included. No patient required conversion to open surgery for LSG, laparoscopic gastric bypass (LGB), or laparoscopic adjustable gastric banding (LAGB) procedures. There were no deaths, and the complication rate was 12.1% (range 10%–13.2%) in the LSG group versus 20.9% (range 10%–26.4%) in the LGB group, and 0% in the LAGB group (only 1 RCT). The complications included leakage, bleeding, stricture, and reoperation that occurred with rates of .9%, 3.3%, 0%, and 2.1%, respectively, in the LSG group and rates of 0%, 5%, 0%, and 4%, respectively, in the LGB group. The average operating time in the LSG group was 106.5 minutes versus 132.3 minutes in the LGB group. The percentage of excess weight loss (%EWL) ranged from 49% to 81% in the LSG group, from 62.1% to 94.4% in the LGB group, and from 28.7% to 48% in the LAGB group, with a follow-up ranging from 6 months to 3 years. The type 2 diabetes mellitus (T2DM) remission rate ranged from 26.5% to 75% in the LSG group and from 42% to 93% in the LGB group.ConclusionsLSG is a well-tolerated, feasible procedure with a relatively short operating time. Its effectiveness in terms of weight loss is confirmed for short-term follow-up (≤3 years). The role of LSG in the treatment of T2DM requires further investigation. 相似文献

Laparoscopic Bariatric Surgery in Super-obese Patients (BMI>50) is Safe and Effective: A Review of 332 Patients 总被引:2,自引:2,他引:0
Background: Bariatric surgery in super-obese patients (BMI >50 kg/m2) can be challenging because of difficulties in exposure of visceral fat, retracting the fatty liver, and strong torque applied
to instruments, as well as existing co-morbidities. Methods: A retrospective review of super-obese patients who underwent
laparoscopic adjustable gastric banding (LAGB n=192), Roux-en-Y gastric bypass (RYGBP n=97), and biliopancreatic diversion
with/without duodenal switch (BPD n= 43), was performed. 30day peri-operative morbidity and mortality were evaluated to determine
relative safety of the 3 operations. Results: From October 2000 through June 2004, 331 super-obese patients underwent laparoscopic
bariatric surgery, with mean BMI 55.3 kg/m2. Patients were aged 42 years (13-72), and 75% were female. When categorized by opertaion (LAGB, RYGBP, BPD), the mean age,
BMI and gender were comparable. 6 patients were converted to open (1.8%). LAGB had a 0.5%, RYGBP 2.1% and BPD 7.0% conversion
rate (P=0.02, all groups). Median operative time was 60 min for LAGB, 130 min for RYGBP and 255 min for BPD (P<0.001, all groups). Median length of stay was 24 hours for LAGB, 72 hours for RYGBP, and 96 hours for BPD (P <0.001). Mean %EWL for the LAGB was 35.3±12.6, 45.8±19.4, and 49.5±18.6 with follow-up of 87%, 76% and 72% at 1, 2 and 3
years, respectively. Mean %EWL for the RYGBP was 57.7±15.4, 54.7±21.2, and 56.8±21.1 with follow-up of 76%, 33% and 54% at
1, 2 and 3 years, respectively. Mean %EWL for the BPD was 60.6±15.9, 69.4±13.0 and 77.4±11.9 with follow-up of 79%, 43% and
47% at 1, 2 and 3 years, respectively. The difference in %EWL was significant at all time intervals between the LAGB and BPD
(P<0.004). However, there was no significant difference in %EWL between LAGB and RYGBP at 2 and 3 years. Overall perioperative
morbidity occurred in 27 patients (8.1%). LAGB had 4.7% morbidity rate, RYGBP 11.3%, and BPD 16.3% (P=0.02, all groups). There were no deaths. Conclusion: Laparoscopic bariatric surgery is safe in super-obese patients. LAGB,
the least invasive procedure, resulted in the lowest operative times, the lowest conversion rate, the shortest hospital stay
and the lowest morbidity in this high-risk cohort of patients. Rates of all parameters studied increased with increasing procedural
complexity. However, the difference in %EWL between RYGBP and LAGB at 2 and 3 years was not statistically significant. 相似文献

Background
Before bariatric surgery, some patients with type 2 diabetes mellitus (T2DM) experience improvement in blood glucose control and reduced insulin requirements while on a preoperative low-calorie diet (LCD). We hypothesized that patients who exhibit a significant glycemic response to this diet are more likely to experience remission of their diabetes in the postoperative period.Materials and methods
Insulin-dependent T2DM patients undergoing bariatric surgery between August 2006 and February 2011 were eligible for inclusion. Insulin requirements at day 0 and 10 of the LCD were compared. Patients with a ≥50% reduction in total insulin dosage to maintain appropriate blood glucose control were considered rapid responders to the preoperative LCD. All others were non–rapid responders. We analyzed T2DM remission rates up to 1 y postoperatively.Results
A total of 51 patients met inclusion criteria and 29 were categorized as rapid responders (57%). The remaining 22 were considered non–rapid responders (43%). The two groups did not differ demographically. Rapid responders had greater T2DM remission rates at 6 (44% versus 13.6%; P = 0.02) and 12 mo (72.7% versus 5.9%; P < 0.01). In patients undergoing laparoscopic gastric bypass, rapid responders showed greater excess weight loss at 3 mo (40.1% versus 28.2%; P < 0.01), 6 mo (55.2% versus 40.2%; P < 0.01), and 12 mo (67.7% versus 47.3%; P < 0.01).Conclusions
Insulin-dependent T2DM bariatric surgery patients who display a rapid glycemic response to the preoperative LCD are more likely to experience early remission of T2DM postoperatively and greater weight loss. 相似文献5.
Objective
This meta-analysis was conducted to determine the effect of percent excess weight loss (%EWL) after bariatric surgery on diabetes remission.Methods
The Cochrane Library, PubMed, MEDLINE, Embase, and CINAHL were searched. All reports on %EWL involving humans and published in English between 1 January 1992 and 1 September 2013 were included in the analysis.Results
Eight studies involving 1,247 patients who underwent bariatric surgery were selected. %EWL was positively associated with remission rate (WMD?=?11.15, 95 % CI: 6.73–15.56, p?0.01) in the Caucasian population.Conclusions
Patients with extensive weight loss were more likely to achieve T2DM remission after bariatric surgery. Further randomized controlled trials (RCTs) with uniform remission criterion should be performed to provide more reliable evidence. 相似文献6.
Background
Several studies have been investigated to find the long-term effect of bariatric surgery on weight loss; nevertheless, a meta-analysis can detailedly demonstrate the effect of bariatric surgery on weight in morbidly obese patients. This study aimed to assess the long- and very long-term effects of laparoscopic adjustable gastric banding (LAGB), laparoscopic Roux-en-Y gastric bypass (LRYGB), and laparoscopic sleeve gastrectomy (LSG) on weight loss in adults.Methods
An electronic search using PubMed, Scopus, and Google scholar databases was performed for all English-language articles up to May 15, 2016 with no publication date restriction. Outcome was long-term (≥5–10 years) and very long-term (≥10 years) weight reduction that reported as the mean %EWL and changes in BMI from baseline.Results
Eighty articles with 87 arms were included in this meta-analysis. The excess weight loss percentage (%EWL) was 47.94% and 47.43% after LAGB at ≥5 and ≥10 years, respectively. After LRYGB the %EWL was 62.58% at ≥5 years and 63.52% at ≥10 years. It was 53.25% at ≥5 years after LSG. Results of subgroup analyses have indicated that LRYGB leads to higher %EWL in America and Asia compared with Europe. Meta-regression analyses have shown that there is no significant association between %EWL and baseline age, BMI and length of follow-up after three procedures. However, there is a positive association between gender and %EWL after LRYGB (β?=?1.24). No publication bias was found.Conclusions
These findings suggest that LRYGB is an effective procedure in morbidly obese patients that leads to sustainable weight loss over the long- and very long-term periods in compared with LAGB and LSG.7.

Type 2 diabetes (T2D) remission after bariatric procedures has been highlighted in many retrospective and some recent prospective studies. However, in the most recent prospective study, more than 50 % of patients did not reach T2D remission at 1 year. Our aim was to identify baseline positive predictors for T2D remission at 1 year after bariatric surgery and to build a preoperative predictive score. We analysed the data concerning 161 obese operated on between June 2007 and December 2010. Among them, 46 were diabetic and were included in the study—11 laparoscopic adjustable gastric banding (LAGB), 26 Roux-en-Y gastric bypass (RYGB) and 9 sleeve gastrectomy (SG). We compared anthropometric and metabolic features during 1 year of follow-up. A receiver operating characteristic analysis was performed to predict T2D remission. RYGB and SG were similarly efficient for body weight loss and more efficient than LAGB; 62.8 % of patients presented with T2DM remission at 1 year, with no significant difference according to the surgical procedure. A 1-year body mass index (BMI) <35 kg?m?2 was predictive of T2DM remission whatever the procedure. The preoperative predictive factors of diabetes remission were baseline BMI ≤50 kg?m?2, duration of type 2 diabetes ≤4 years, glycated haemoglobin ≤7.1 %, fasting glucose <1.14 g/l and absence of insulin therapy. A short duration of diabetes and good preoperative glycaemic control increase the rate of T2DM remission 1 year after surgery. Preoperative metabolic data could be of greater importance than the choice of bariatric procedure. 相似文献

Objective
The objective of this study was to determine whether the DiaRem, a score that predicts type 2 diabetes (T2D) remission following roux-en-y gastric bariatric surgery (RYGB), also predicts remission following laparoscopic adjustable gastric banding (LAGB) and laparoscopic sleeve gastrectomy (LSG) in white and Hispanic patients.Background
While bariatric surgery is highly effective in reversing insulin resistance, there are patients for whom surgery will not lead to remission. To date, there is no score for predicting remission following LAGB or LSG surgery. Additionally, there is little known about how to predict whether Hispanic patients will experience remission.Methods
We conducted a retrospective cohort study of white and Hispanic patients with T2D who received bariatric surgery. There were 361 white and 130 Hispanic patients among whom 328 had RYGB surgery, 107 had LSG surgery, and 56 had LAGB surgery. We used age, diabetes treatment, and hemoglobin A1c to calculate DiaRem scores. Mann-Whitney U test was used to determine the association between DiaRem scores and remission. Area under the receiver operant curve (AUC) was used to assess the ability of the DiaRem to discriminate between patients who did and did not remit.Results
The DiaRem was associated with partial remission in all surgery types for white and Hispanic patients (Mann-Whitney, p < 0.001). The DiaRem had moderate to high discriminant ability (AUC > 0.70) for all surgical and racial/ethnic groups.Conclusions
The DiaRem distinguishes between patients likely and unlikely to experience remission, informing expectations of patients making T2D treatment decisions.9.

BackgroundObstructive sleep apnea (OSA) is strongly associated with metabolic syndrome. Bariatric surgery is an effective available treatment for OSA; however, limited research predicts which patients undergoing bariatric surgery will undergo OSA resolution.ObjectivesTo determine perioperative predictors for OSA resolution following bariatric surgery using a national database.SettingUnited Kingdom national bariatric surgery database.MethodsThe UK National Bariatric Surgery Registry (NBSR) was interrogated to identify all patients with OSA that underwent primary bariatric surgery between January 2009 and June 2017. Those with at least 1 follow-up recording postoperative OSA status were selected for further analysis. Demographic, pre- and postoperative outcomes were collected and analyzed. Poisson multivariate regression was conducted to identify predictors of OSA remission.ResultsA total of 4015 bariatric cases were eligible for inclusion: 2482 (61.8%) patients underwent laparoscopic Roux-en-Y gastric bypass (LRYGB), 1196 (29.8%) sleeve gastrectomy (LSG), and 337 (8.4%) adjustable gastric banding (LAGB). Overall, the mean excess weight loss (EWL) % for the whole group was 61.2 (SD ± 27.2). OSA resolution was recorded in 2377 (59.2%) patients. Following Poisson regression, LRYGB (risk ratio [RR], 1.49 confidence interval [CI] 1.25–1.78) and LSG (RR, 1.46 [CI 1.22–1.75] were associated with approximately 50% increased likelihood of OSA remission compared with LAGB. Greater weight loss following intervention was associated with greater likelihood of OSA remission, while both greater age and greater preoperative body mass index (BMI) were associated with reduced likelihood of OSA remission (P < .001).ConclusionThis study demonstrated that metabolic surgery results in OSA remission in the majority of patients with obesity. Younger age, lower BMI preprocedure, greater %EWL and the use of LSG or LRYGB positively predicted OSA remission. 相似文献

Background
Obesity becomes a global epidemic disease, and bariatric surgery is increasing in Korea as well as in western countries. The first laparoscopic Roux-en-Y gastric bypass (LRYGBP) was performed in 2003, and the Lap Band® was approved for use in Korea in 2004. There are no data regarding gastric bypass and adjustable gastric banding regarding weight loss as well as changing of pre-existing comorbidities up to date.Methods
St. Mary’s Hospital Center, main leader of bariatric surgery in Korea, performed 76 weight loss operations [LRYGBP?=?25, laparoscopic adjustable gastric banding (LAGB) ?=?51] for morbid obesity. We retrospectively reviewed a series of bariatric cases and examined changes of weight loss, postoperative complications, and pre-existing comorbidities between two procedures.Results
There were no significant differences in age, BMI, sex distribution, pre-existing comorbidities in two procedures. Patients undergoing LRYGBP had longer operative times, more blood loss, and longer hospital stays. There is significant difference regarding postoperative complication (p?0.05) but neither for mortality nor pulmonary embolism with both procedures. Percentage of excess weight loss (%EWL) of LRYGBP at 12, 24, and 36 months were 76.9%, 79.7%, and 85.8%, and %EWL of LAGB were 46.8%, 55.1%, 63.3%, respectively. The patients in the LRYGBP who has dyslipidemia, sleep apnea, degenerative joint disease, and diabetes mellitus were more likely to improve than the patients after LAGB at early postoperative period.Conclusions
The results of our initial study indicate that LRYGBP and LAGB are technically feasible and safe. It is a low rate of major postoperative complications without mortality. LRYGBP and LAGB are quite satisfactory and promising bariatric procedures with significant weight loss and improvement of obesity-related metabolic comorbidities in Korean.11.

BackgroundSurgery is the most effective treatment of morbid obesity and leads to dramatic improvements in type 2 diabetes mellitus (T2DM). Gastrointestinal metabolic surgery has been proposed as a treatment option for T2DM. However, a grading system to categorize and predict the outcome of metabolic surgery is lacking. The study setting was a tertiary referral hospital (Taoyuan City, Taoyuan County, Taiwan).MethodsWe first evaluated 63 patients and identified 4 factors that predicted the success of T2DM remission after bariatric surgery in this cohort: body mass index, C-peptide level, T2DM duration, and patient age. We used these variables to construct the Diabetes Surgery Score, a multidimensional 10-point scale along which greater scores indicate a better chance of T2DM remission. We then validated the index in a prospective collected cohort of 176 patients, using remission of T2DM at 1 year after surgery as the outcome variable.ResultsA total of 48 T2DM remissions occurred among the 63 patients and 115 remissions (65.3%) in the validation cohort. Patients with T2DM remission after surgery had a greater Diabetes Surgery Score than those without (8 ± 4 versus 4 ± 4, P < .05). Patients with a greater Diabetes Surgery Score also had a greater rate of success with T2DM remission (from 33% at score 0 to 100% at score 10); A 1-point increase in the Diabetes Surgery Score translated to an absolute 6.7% in the success rate.ConclusionThe Diabetes Surgery Score is a simple multidimensional grading system that can predict the success of T2DM treatment using bariatric surgery among patients with inadequately controlled T2DM. 相似文献

Background
Alanine aminotransferase (ALT) is used to detect non-alcoholic fatty liver disease and has been associated with increased risk of metabolic syndrome and type II diabetes mellitus (T2DM). Bariatric procedures result in significant weight loss and a rapid resolution of T2DM. We aimed to study the impact of bariatric interventions on ALT levels in patients with or without T2DM and compare this effect between different types of weight-loss procedures.Methods
We reviewed 756 patients undergoing bariatric surgery. Demographics, co-morbidities, baseline and post-operative ALT and HbA1C levels, weight-loss data, and diabetes status were recorded. ALT levels were compared between different procedures and between diabetic and non-diabetic patients. Chi-square test, ANOVA, and t test were used to evaluate outcomes.Results
Males and diabetics had significantly higher ALT at baseline. Both Roux-en-Y gastric bypass surgery (RYGB) and laparoscopic adjustable gastric banding (LAGB) resulted in significant reduction in ALT levels beginning at the third post-operative month (20 and 17?%, respectively, compared to baseline, p?0.001). ALT remained at the new low level up to year 3 after surgery. The degree of reduction was similar for both procedures and was independent of the degree of weight loss. In diabetics, ALT reduction was associated with improvement in disease; but in T2DM patients who remained on insulin, ALT remained elevated.Conclusions
RYGB and LAGB decrease ALT levels to the same degree and independent of weight loss. Our data confirm higher ALT in diabetics and demonstrate a rapid normalization after bariatric surgery with a simultaneous decrease in HbA1C. These results suggest that ALT may be used as a marker of metabolic improvement after bariatric surgery. 相似文献13.

Objective
The objective of the study is to evaluate the effect of gastric banding, gastric bypass and sleeve gastrectomy on medium to long-term diabetes control in obese participants with type 2 diabetes mellitus.Research Design and Methods
Matched cohort study using primary care electronic health records from the UK Clinical Practice Research Datalink. Obese participants with type 2 diabetes who received bariatric surgery from 2002 to 2014 were compared with matched control participants who did not receive BS. Remission was defined for each year of follow-up as HbA1c <6.5 % and no antidiabetic drugs prescribed.Results
There were 826 obese participants with T2DM who received bariatric surgery including adjustable gastric banding (LAGB) 220; gastric bypass (GBP) 449; or sleeve gastrectomy (SG) 153; with four procedures undefined. Mean HbA1c declined from 8.0 % before BS to 6.5 % in the second postoperative year; proportion with HbA1c <6.5 % (<48 mmol/mol) increased from 17 to 47 %. The proportion of patients in remission was 30 % in the second year, being 20 % for LAGB, 34 % for GBP and 38 % for SG. The adjusted relative rate of remission over the first six postoperative years was 5.97 (4.86 to 7.33, P?<?0.001) overall; for LAGB 3.32 (2.27 to 4.86); GBP 7.16 (5.64 to 9.08); and SG 6.82 (5.05 to 9.19). Rates of remission were maintained into the sixth year of follow-up.Conclusions
Remission of diabetes may continue for up to 6 years after bariatric surgical procedures. Diabetes outcomes are generally more favourable after gastric bypass or sleeve gastrectomy than LAGB.14.

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.

BackgroundThere is no evidence that insurance-mandated weight loss before bariatric surgery affects outcomes.ObjectiveThis retrospective study evaluated the relationship between insurance-mandated weight management program (WMP) completion before primary bariatric surgery and postoperative outcomes.SettingSuburban academic medical center.MethodsPatients who underwent laparoscopic Roux-en-Y gastric bypass (LRYGB, n = 572) or sleeve gastrectomy (SG, n = 484) from 2014 to 2019 were dichotomized to presence (LRYGB n = 431, SG n = 348) or absence (LRYGB n = 141, SG n = 136) of insurance-mandated WMP completion. Primary endpoints included follow-up rate, percent total weight loss (%TWL), and percent excess weight loss (%EWL) through 60 months after surgery. The Mann-Whitney U test compared between-group means with significance at P < .05.ResultsFollow-up rate, %TWL, and %EWL were not different (P = NS) up to 60 months postoperation between groups for either surgery. Both LRYGB and SG patients without WMP completion maintained greater %TWL (LRYGB: 34.4 ± 11.1% versus 29.8 ± 11.0%, P = .159; SG: 21.4 ± 10.0% versus 18.2 ± 10.5%, P = .456) and %EWL (LRYGB: 71.3 ± 26.3% versus 67.6 ± 26.5%, P = .618; SG: 49.2 ± 18.8% versus 47.5 ± 28.8%, P = .753) at 36 months after surgery. Secondarily, duration of time to get to surgery was significantly greater among yes-WMP patients (LRYGB: 178 days versus 121 days, P < .001; SG: 169 days versus 95 days, P < .001).ConclusionInsurance-mandated WMP completion before bariatric surgery delays patient access to surgery without improving postoperative weight loss potential and must be abandoned. 相似文献

Background: Controversy exists regarding the best surgical treatment for super-obesity (BMI >50 kg/m 2 ). The two most common
bariatric procedures performed worldwide are laparoscopic adjustable gastric banding (LAGB) and laparoscopic Roux-en-Y gastric
bypass (LRYGBP). We undertook a retrospective single-center study to compare the safety and efficacy of these two operations
in super-obese patients. Methods: 290 super-obese patients underwent laparoscopic bariatric surgery: 179 LAGB and 111 LRYGBP.
Results: There were one death in both groups. The early complication rate was higher in the LAGB group (10% vs 2.8%, P<0.01). Late complication rate was higher in the LAGB group (26% vs 15.3%, P<0.05). Operating time and hospital stay were significantly higher in the LRYGBP group. LRYGBP had significantly better excess
weight loss than LAGB (63% vs 41% at 1 year, and 73% vs 46% at 2 years), as well as lower BMI than LAGB (35 vs 41 at 18 months).
Conclusion: LRYGBP results in significantly greater weight loss than LAGB in super-obese patients, but is associated with
a higher early complication rate. 相似文献

Background
Several studies have demonstrated a high rate of type 2 diabetes mellitus (T2DM) resolution after sleeve gastrectomy. Different prognostic factors have been hypothesized for T2DM remission after bariatric surgery. Our objectives were to analyze the role of T2DM duration as an independent prognostic factor for remission.Methods
From January 2008 to September 2010, 56 obese patients with T2DM underwent sleeve gastrectomy. Group A consisted of 16 patients who had lived with T2DM for >10 years (12 women and 4 men, mean body mass index 42.7 kg/m2). Group B included 40 obese patients who had lived with T2DM for <10 years (29 women and 11 men, mean body mass index 44.9 kg/m2).Results
In group A, 43.7% were treated with oral hypoglycemics, 6.3% with insulin, and 50% with oral hypoglycemics and insulin. In group B, 87.5% were treated with oral hypoglycemics, 5% with dietary therapy, and 7.5% with insulin. The preoperative average glycemia, glycosylated hemoglobin, and C-peptide value was 206.2 mg/dL, 9.5%, and 2.8 μg/L in group A and 134 mg/dL, 7.1%, and 4.5 μg/L in group B, respectively (P < .05 for all). The T2DM remission rate in all 56 patients was 80.3%. However, in group B, the resolution rate was 100%, but in group A, the resolution rate was 31%. Patients without complete remission were more sensitive to lower doses of antidiabetic drugs.Conclusion
Sleeve gastrectomy is effective in the treatment of obese patients with T2DM. The duration of T2DM seems to be of paramount importance as a prognostic factor, with 10 years representing a cutoff between a 100% rate of remission and significantly lower rates of remission. 相似文献18.

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19.

BackgroundStudies have shown that type 2 diabetes (T2DM) improves or resolves shortly after Roux-en-Y gastric bypass (RYGB). Few data are available on T2DM recurrence or the effect of weight regain on T2DM status.MethodsA review of 42 RYGB patients with T2DM and ≥3 years of follow-up and laboratory data was performed. Postoperative weight loss and T2DM status was assessed. Recurrence or worsening was defined as hemoglobin A1c >6.0% and fasting glucose >124 mg/dL and/or medication required after remission or improvement. Patients whose T2DM recurred or worsened were compared with those whose did not, and patients whose T2DM improved were compared with those whose T2DM resolved.ResultsT2DM had either resolved or improved in all patients (64% and 36%, respectively); 24% (10) recurred or worsened. The patients with recurrence or worsening had had a lower preoperative body mass index than those without recurrence or worsening (47.9 versus 52.9 kg/m2; P = .05), regained a greater percentage of their lost weight (37.7% versus 15.4%; P = .002), had a greater weight loss failure rate (63% versus 14%; P = .03), and had greater postoperative glucose levels (138 versus 102 mg/dL; P = .0002). Patients who required insulin or oral medication before RYGB were more likely to experience improvement rather than resolution (92% versus 8%, P ≤.0001; and 85% versus 15%; P = .0006, respectively).ConclusionOur results have shown that beyond 3 years after RYGB, the incidence of T2DM recurrence or worsening in patients with initial resolution or improvement was significant. In our patients, a greater likelihood of recurrence or worsening of T2DM was associated with a lower preoperative body mass index. Before widespread acceptance of bariatric surgery as a definitive treatment for those with T2DM can be achieved, additional study of this recurrence phenomenon is indicated. 相似文献
