不同类型减重代谢手术治疗重度肥胖合并2型糖尿病的近期疗效分析

背景与目的：减重代谢手术是肥胖合并2型糖尿病（T2DM）的有效治疗方式,但不同的减重代谢手术在治疗肥胖症和控制血糖等方面效果不同。因此,本研究探讨不同减重代谢手术方式治疗重度肥胖合并T2DM的短期疗效,以及它们在减重、降糖、降脂等方面的特点,以期为临床治疗选择提供参考。 方法：回顾分析63例行减重代谢手术重度肥胖合并T2DM患者的临床资料。其中25例行腹腔镜胃袖状切除（LSG）,18例行LSG+空肠旁路术（LSG+JJB）,20例行腹腔镜胃旁路术（LRYGB）,比较三组患者术前及术后6、12个月的临床数据。 结果：三组术前各项资料具有可比性。所有患者均顺利完成手术,三组手术时间比较差异有统计学意义（P<0.05）,其余手术相关指标差异均无统计学意义（均P>0.05）。三组术后体质量、腰围、臀围、BMI、多余体质量减少百分比（%EWL）等减重指标均较术前明显改善（均P>0.05）,除臀围在同组术后6个月与12个月以及三组间术后相同时间点差异均无统计学意义外（均P>0.05）,其余4项指标均为同组术后12个月明显优于术后6个月、同时间点LSG+JJB组与LRYGB组优于LSG组（均P<0.05）,而LSG+JJB组与LRYGB组间差异无统计学意义（均P>0.05）。三组患者术后空腹血糖、空腹胰岛素、糖化血红蛋白、胰岛素抵抗指数等糖代谢指标均较术前明显改善（均P<0.05）,但以上指标在同组术后6个月与12个月间以及三组同时间点差异均无统计学意义（均P>0.05）;三组术后6、12个月糖尿病缓解率比较,差异均无统计学意义（均P>0.05）。三组患者术后血胆固醇、甘油三脂、低密度脂蛋白、高密度脂蛋白、尿酸等脂代谢指标均较术前明显改善（均P<0.05）,三组间甘油三脂、高密度脂蛋白、低密度脂蛋白改善效果差异无统计学意义（均P>0.05）,LRYGB组、LSG+JJB组血尿酸及胆固醇降低程度均优于LSG组（均P<0.05）。 结论：LSG、LSG+JJB、LRYGB均有良好的减重及改善糖脂代谢作用,短期效果显著;三者均能有效降低血糖、血脂指标。LSG+JJB和LRYGB的减重、降尿酸、降胆固醇的效果优于LSG。LSG+JJB手术操作简单,效果明显,值得在临床中进一步推广运用。

Comparison Between Laparoscopic Sleeve Gastrectomy and Laparoscopic Adjustable Gastric Banding for Morbid Obesity: a Meta-analysis

Bariatric surgery is now widely accepted for treatment of morbid obesity. This study compared the effects of laparoscopic sleeve gastrectomy (LSG) and laparoscopic adjustable gastric banding (LAGB) on excess weight loss (EWL) and type 2 diabetes mellitus (T2DM). PubMed and Embase were searched for publications concerning LAGB and LSG from 2000 to 2012, with the last search on August 17, 2012. EWL and T2DM improvement over 6 and 12 months were pooled and compared by meta-analysis. Odds ratios (ORs) and mean differences were calculated with 95 % confidence intervals (CIs). Eleven studies involving 1,004 patients met the inclusion criteria. Compared with LAGB, LSG achieved greater EWL. The mean percentage EWL for LAGB was 33.9 % after 6 months in six studies and 37.8 % after 12 months in four studies; for LSG, EWL was 50.6 % after 6 months and 51.8 % after 12 months in the same studies. LSG was also superior to LAGB in treating T2DM. In five studies, T2DM was improved in 42 of 68 (61.8 %) patients after LAGB and 66 of 80 (82.5 %) after LSG, representing a pooled OR of 0.34 (95 % CI 0.16–0.73) and pooled mean differences of ?12.55 (95 % CI ?15.66 to ?9.43) and ?4.97 (95 % CI ?7.58 to ?8.36), respectively. LSG is more effective than LAGB in morbid obesity, with higher percentage EWL and greater improvement in T2DM.

Predictors of remission of type 2 diabetes mellitus after laparoscopic gastric banding and bypass

Background

Type 2 diabetes mellitus (T2DM) is associated with obesity and results in considerable morbidity and mortality. Our objectives were to evaluate the effect of laparoscopic bariatric surgery on the control of T2DM in morbidly obese patients in a U.K. population and to determine the predictors of T2DM remission after bariatric surgery. The study was performed at teaching university hospitals and affiliated private hospitals.

Methods

Of 487 patients who underwent laparoscopic bariatric procedures from 2002 to 2007, 74 patients (15.2%) had established T2DM. The results are presented as the mean values. Multivariate analysis was used to identify the factors predictive of remission of T2DM after bariatric surgery.

Results

The body mass index before laparoscopic gastric bypass (LGB; n = 48) and laparoscopic adjustable gastric banding (LAGB; n = 26) were comparable (52 versus 51 kg/m², P = .508). At a mean follow-up of 16.9 months, 41% had remission and 59% had experienced improvement in T2DM. Although the duration of follow-up was significantly longer for the patients who had undergone LAGB than for those who had undergone LGB (23 versus 13.4 months, P = .001), the percentage of excess weight loss (%EWL) was significantly greater after LGB than after LAGB (59.4% versus 48.8%, P = .031), with an associated greater remission rate of T2DM (50% versus 24%, P = .034). Multivariate analysis revealed a greater %EWL and younger age to be independent predictors of postoperative remission of T2DM, and LGB, longer follow-up, and female gender were independent predictors of a greater %EWL.

Conclusion

The %EWL was the only predictor of remission of T2DM that was influenced by the choice of bariatric procedure. In our study, LGB offered greater weight loss and a chance of remission of T2DM compared with LAGB and within 2 years of surgery.     

Feasibility and technique of laparoscopic conversion of adjustable gastric banding to sleeve gastrectomy

BackgroundTo evaluate the feasibility, safety, and short-term efficacy of the conversion of laparoscopic adjustable gastric banding (LAGB) to laparoscopic sleeve gastrectomy (LSG) because of inadequate weight loss.MethodsThe inclusion criteria were an inadequate percentage of excess weight loss (%EWL), defined as <30% at ≥1 year after LAGB. From August 2002 to October 2007, 27 patients (17 women and 10 men) had undergone removal of their LAGB and conversion to LSG. The average age at LSG was 43.6 ± 11.4 years (range 25–66). Before LAGB, the mean weight and body mass index was 129.8 ± 21.9 kg (range 95–178) and 45 ± 8.1 kg/m² (range 35–64), respectively. The average interval between LAGB and LSG was 51.2 ± 30.1 months (range 22–132). Before conversion, the mean weight, body mass index, and %EWL was 117.9 ± 27.3 kg (range 63–170), 39 ± 9.6 kg/m² (range 24–61), and 18.1% ± 18.3%, respectively. Of the 27 patients, 12 had 19 obesity-related co-morbidities, including arterial hypertension in 7, type 2 diabetes mellitus in 2, degenerative joint disease in 7, and sleep apnea in 3.ResultsThe mean operative time was 120.6 ± 32.4 minutes (range 65–195). No conversion to open surgery was required, and no patient died. The postoperative complications included a subphrenic hematoma that required laparoscopic drainage; no postoperative leaks developed. The mean hospital stay was 3.2 ± 1.4 days (range 2–8). After a mean follow-up of 18.6 ± 14.8 months (range 1–59) for 23 patients (4 patients were lost to follow-up), the mean weight, body mass index, and weight loss was 100.7 ± 23.5 kg (range 61–152), 34.6 ± 8.7 kg/m² (range 21–50.4), and 23 ± 12.4 kg (range 2–55), respectively. The patients had had an additional 16.7% EWL after LSG for a total average %EWL of 34.8% ± 21.8% (P <.05). Of the 12 patients with obesity-related co-morbidities, 5 had had resolution, including arterial hypertension in 1, type 2 diabetes mellitus in 1, degenerative joint disease in 2, and sleep apnea in 2.ConclusionThe results of this study support the safety of LSG in the case of an inadequate %EWL after LAGB. However, the degree of weight loss and co-morbidity resolution is of concern.     

Two-step conversion surgery after failed laparoscopic adjustable gastric banding. Comparison between laparoscopic Roux-en-Y gastric bypass and laparoscopic gastric sleeve

BackgroundDespite its worldwide popularity, laparoscopic adjustable gastric banding (LAGB) requires revisional surgery for failures or complications, in 20–60% of cases. The purpose of this study was to compare in terms of efficacy and safety, the conversion of failed LAGB to laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy. (LSG).MethodsThe bariatric database of our institution was reviewed to identify patients who had undergone conversion of failed LAGB to LRYGB or to LSG, from November 2007 to June 2012.ResultsA total of 108 patients were included. Of these, 74 (68.5%) underwent conversion to LRYGB and 34 to LSG. All of the procedures were performed in 2-stage and laparoscopically. The mean follow-up for the LRYGB group was 29.1±17.9 months while for the LSG patients was 24.2±14.3 months. The mean body mass index (BMI) prior LRYGB and LSG was 45.6±7.8 and 47.5±5.6 (P = .09), respectively. Postoperative complications occurred in 16.2% of the LRYGB patients and in 2.9% of the LSG group (P = .04). Mean percentage of excess weight loss was 59.9%±16.2% and 70.2%±16.7% in LRYGB, and it was 52.2%±11.4% and 59.9%±14.4% in LSG at 12 months (P = .007) and 24 months (P = .01) after conversion.ConclusionIn this series, LRYGB and LSG are both effective and adequate revisional procedure after failure of LAGB. While LRYGB seems to ensure greater weight loss at 24 months follow-up, LSG is associated with a lower postoperative morbidity.
