Comparative long-term mortality after laparoscopic adjustable gastric banding versus nonsurgical controls

Surgery for Obesity and Related Diseases, 2007

Background: To compare the mortality rate of obese patients treated by laparoscopic gastric banding (LAGB) with the mortality rate of matched obese patients observed at medical centers. The net effect of bariatric surgery on total mortality is still controversial. Gastric bypass has been shown to reduce the relative risk of death, but similar data with LABG are still lacking. Methods: The surgical series was composed of 821 patients with a body mass index (BMI) Ͼ40 kg/m 2 consecutively treated with LAGB at Padova University, Italy. The reference group was composed of 821 gender-, age-, and BMI-matched patients selected from a sample of 4681 adults with a BMI Ͼ40 kg/m 2 observed at 6 Italian medical centers not using surgical therapy. Results: The mean follow-up was 5.6 Ϯ 1.9 and 7.2 Ϯ 1.2 years in the surgical and reference group, respectively. The vital status was known in 97.6% of the surgical group (8 deaths) and in 97.4% of the reference group (36 deaths). In the surgical group, the percentage of excess weight loss was 39.8% Ϯ 17.9% 1 year after LAGB and 37.2% Ϯ 23.8% 5 years after LAGB. The rate of late revisional surgery was 12.2%. Survival was estimated using the Kaplan-Meier method, and the differences between the 2 groups were evaluated using the log-rank test. The survival rate was significantly greater in the surgical group (P ϭ 0.0004). On multivariate Cox analysis, the 5-year relative risk of death in the surgical group, adjusted for gender, age, and baseline BMI, was 0.36 (95% confidence interval 0.16 -0.80). Conclusion: LAGB was associated with a 0% operative mortality rate and 40% stable excess weight loss. LAGB patients had a 5-year 60% lower risk of death than comparable morbidly obese patients.

Laparoscopic adjustable gastric banding versus Roux-en-Y gastric bypass: 5-year results of a prospective randomized trial

Surgery for Obesity and Related Diseases, 2007

Background: To perform a prospective, randomized comparison of laparoscopic adjustable gastric banding (LAGB) and laparoscopic Roux-en-Y gastric bypass (LRYGB). Methods: LAGB, using the pars flaccida technique, and standard LRYGB were performed. From January 2000 to November 2000, 51 patients (mean age 34.0 Ϯ 8.9 years, range 20-49) were randomly allocated to undergo either LAGB (n ϭ 27, 5 men and 22 women, mean age 33.3 years, mean weight 120 kg, mean body mass index [BMI] 43.4 kg/m 2 ; percentage of excess weight loss 83.8%) or LRYGB (n ϭ 24, 4 men and 20 women, mean age 34.7, mean weight 120 kg, mean BMI 43.8 kg/m 2 , percentage of excess weight loss 83.3). Data on the operative time, complications, reoperations with hospital stay, weight, BMI, percentage of excess weight loss, and co-morbidities were collected yearly. Failure was considered a BMI of Ͼ35 at 5 years postoperatively. The data were analyzed using Student's t test and Fisher's exact test, with P Ͻ.05 considered significant. Results: The mean operative time was 60 Ϯ 20 minutes for the LAGB group and 220 Ϯ 100 minutes for the LRYGB group (P Ͻ.001). One patient in the LAGB group was lost to follow-up. No patient died. Conversion to laparotomy was performed in 1 (4.2%) of 24 LRYGB patients because of a posterior leak of the gastrojejunal anastomosis. Reoperations were required in 4 (15.2%) of 26 LAGB patients, 2 because of gastric pouch dilation and 2 because of unsatisfactory weight loss. One of these patients required conversion to biliopancreatic diversion; the remaining 3 patients were on the waiting list for LRYGB. Reoperations were required in 3 (12.5%) of the 24 LRYGB patients, and each was because of a potentially lethal complication. No LAGB patient required reoperation because of an early complication. Of the 27 LAGB patients, 3 had hypertension and 1 had sleep apnea. Of the 24 LRYGB patients, 2 had hyperlipemia, 1 had hypertension, and 1 had type 2 diabetes. Five years after surgery, the diabetes, sleep apnea, and hyperlipemia had resolved. At the 5-year (range 60-66 months) follow-up visit, the LRYGB patients had significantly lower weight and BMI and a greater percentage of excess weight loss than did the LAGB patients. Weight loss failure (BMI Ͼ35 kg/m 2 at 5 yr) was observed in 9 (34.6%) of 26 LAGB patients and in 1 (4.2%) of 24 LRYGB patients (P Ͻ.001). Of the 26 patients in the LAGB group and 24 in the LRYGB group, 3 (11.5%) and 15 (62.5%) had a BMI of Ͻ30 kg/m 2 , respectively (P Ͻ.001). Conclusion: The results of our study have shown that LRYGB results in better weight loss and a reduced number of failures compared with LAGB, despite the significantly longer operative time and life-threatening complications.

Conversion of failed gastric banding into four different bariatric procedures

Surgery for Obesity and Related Diseases, 2012

Background: The most common bariatric operation in Europe, laparoscopic adjustable gastric banding (LAGB), is reported to have a high incidence of long-term complications. Also, insufficient weight loss is reported. The optimal conversion technique is unknown. Our objective was to report our experience in the conversions of failed laparoscopic gastric banding procedures to 4 different bariatric procedures at a university hospital. Methods: From March 2006 to December 2010, 630 bariatric operations were performed. Of these patients, 45 underwent conversion of failed LAGB (n ϭ 38) and nonadjustable gastric banding (n ϭ 7). Using a prospectively collected database, we analyzed these procedures. Results: The 45 patients underwent laparoscopic conversion of failed LAGB (n ϭ 38) and nonadjustable gastric banding (n ϭ 7) to 4 different procedures. Of the 45 patients, 18 underwent conversion to laparoscopic sleeve gastrectomy, 18 to laparoscopic Roux-en-Y gastric bypass, 7 to laparoscopic biliopancreatic diversion with duodenal switch, and 2 to laparoscopic biliopancreatic diversion. All conversions but 1 were completed laparoscopically. The mean operating time and hospital stay for laparoscopic sleeve gastrectomy, laparoscopic Roux-en-Y gastric bypass, laparoscopic biliopancreatic diversion with duodenal switch, and biliopancreatic diversion was 111 Ϯ 28 minutes and 4.3 Ϯ 1.4 days, 195 Ϯ 59 minutes and 3.9 Ϯ 1.5 days, 248 Ϯ 113 minutes, and 5.9 Ϯ 2.6 days, and 203 minutes and 6.5 days, respectively. No patient died. Perioperative complications occurred in 4 patients (9.8%). The mean body mass index decreased from 41.5 Ϯ 8 kg/m 2 to 31.3 Ϯ 6.8 kg/m 2 during a mean follow-up period of 13.7 Ϯ 9.6 months. Although laparoscopic biliopancreatic diversion with and without duodenal switch had the greatest preoperative body mass index, they achieved the greatest excess weight loss. Conclusion: Conversion of LAGB or nonadjustable gastric banding to laparoscopic sleeve gastrectomy, laparoscopic Roux-en-Y gastric bypass, and laparoscopic biliopancreatic diversion with or without duodenal switch is feasible and effective to treat the complications of LAGB and to further reduce the weight of morbidly obese patients.

Laparoscopic Gastric Banding Outcomes Do Not Depend on Device or Technique. Long-Term Results of a Prospective Randomized Study Comparing the Lapband® and the SAGB®

Obesity Surgery, 2013

Background Gastric banding still represents one of the most widely used bariatric procedures. It provides acceptable weight loss in many patients, but has frequent longterm complications. Because different types of bands may lead to different results, we designed a randomized study to compare the Lapband® with the SAGB®. We hereby report on the long-term results. Methods Between December 1998 and June 2002, 180 morbidly obese patients were randomized between Lapband® or SAGB®. Weight loss, long-term morbidity, and need for reoperation were evaluated. Results Long-term weight loss did not differ between the two bands. Patients who maintained their band had an acceptable long-term weight loss of between 50 and 60 % EBMIL. In both groups, about half the patients developed long-term complications, with about 50 % requiring major redo surgery. There was no difference in the overall rates of long-term complications or failures between the two groups, but patients who had a Lapband® were significantly more prone to develop band slippage/pouch dilatation (13.3 versus 0 %, p <0,001). Conclusions Although in the absence of complication, gastric banding leads to acceptable weight loss; the long-term complication and major reoperation rates are very high independently from the type of band used or on the operative technique. Gastric banding leads to relatively poor overall long-term results and therefore should not be considered the procedure of choice for the treatment of morbid obesity. Patients should be informed of the limited overall weight loss and the very high complication rates.

The By-Band study: gastric bypass or adjustable gastric band surgery to treat morbid obesity: study protocol for a multi-centre randomised controlled trial with an internal pilot phase

Trials, 2014

Background: The prevalence of severe and complex obesity is increasing worldwide and surgery may offer an effective and lasting treatment. Laparoscopic adjustable gastric band and Roux-en-Y gastric bypass surgery are the two main surgical procedures performed. Design: This open parallel-group randomised controlled trial will compare the effectiveness, cost-effectiveness and acceptability of gastric band (Band) versus gastric bypass (Bypass) in adults with severe and complex obesity. It has an internal pilot phase (in two centres) with integrated qualitative research to establish effective and optimal methods for recruitment. Adults with a body mass index (BMI) of 40 kg/m 2 or more, or a BMI of 35 kg/m 2 or more and other co-morbidities will be recruited. At the end of the internal pilot the study will expand into more centres if the pre-set progression criteria of numbers and rates of eligible patients screened and randomised are met and if the expected rates of retention and adherence to treatment allocation are achieved. The trial will test the joint hypotheses that Bypass is non-inferior to Band with respect to more than 50% excess weight loss and that Bypass is superior to Band with respect to health related quality of life (HRQOL, EQ-5D) at three years. Secondary outcomes include other weight loss measures, waist circumference and remission/resolution of co-morbidities; generic and symptom-specific HRQOL; nutritional blood test results; resource use; eating behaviours and adverse events. A core outcome set for reporting the results of obesity surgery will be developed and a systematic review of the evidence for sleeve gastrectomy undertaken to inform the main study design. Discussion: By-Band is the first pragmatic study to compare the two most commonly performed bariatric surgical procedures for severe and complex obesity. The design will enable and empower surgeons to learn to recruit and participate in a randomised study. Early evidence shows that timely recruitment is possible.

Gastric Banding or Bypass? A Systematic Review Comparing the Two Most Popular Bariatric Procedures

The American Journal of Medicine, 2008

OBJECTIVE: Bariatric surgical procedures have increased exponentially in the United States. Laparoscopic adjustable gastric banding is now promoted as a safer, potentially reversible and effective alternative to Roux-en-Y gastric bypass, the current standard of care. This study evaluated the balance of patient-oriented clinical outcomes for laparoscopic adjustable gastric banding and Roux-en-Y gastric bypass. METHODS: The MEDLINE database (1966 to January 2007, Cochrane clinical trials database, Cochrane reviews database, and Database of Abstracts of Reviews of Effects were searched using the key terms gastroplasty, gastric bypass, laparoscopy, Swedish band, and gastric banding. Studies with at least 1 year of follow-up that directly compared laparoscopic adjustable gastric banding with Roux-en-Y gastric bypass were included. Resolution of obesity-related comorbidities, percentage of excess body weight loss, quality of life, perioperative complications, and long-term adverse events were the abstracted outcomes. RESULTS: The search identified 14 comparative studies (1 randomized trial). Few studies reported outcomes beyond 1 year. Excess body weight loss at 1 year was consistently greater for Roux-en-Y gastric bypass than laparoscopic adjustable gastric banding (median difference, 26%; range, 19%-34%; P Ͻ .001). Resolution of comorbidities was greater after Roux-en-Y gastric bypass. In the highest-quality study, excess body weight loss was 76% with Roux-en-Y gastric bypass versus 48% with laparoscopic adjustable gastric banding, and diabetes resolved in 78% versus 50% of cases, respectively. Both operating room time and length of hospitalization were shorter for those undergoing laparoscopic adjustable gastric banding. Adverse events were inconsistently reported. Operative mortality was less than 0.5% for both procedures. Perioperative complications were more common with Roux-en-Y gastric bypass (9% vs 5%), whereas long-term reoperation rates were lower after Roux-en-Y gastric bypass (16% vs 24%). Patient satisfaction favored Roux-en-Y gastric bypass (P ϭ .006). CONCLUSION: Weight loss outcomes strongly favored Roux-en-Y gastric bypass over laparoscopic adjustable gastric banding. Patients treated with laparoscopic adjustable gastric banding had lower short-term morbidity than those treated with Roux-en-Y gastric bypass, but reoperation rates were higher among patients who received laparoscopic adjustable gastric banding. Gastric bypass should remain the primary bariatric procedure used to treat obesity in the United States.
