Large series examining laparoscopic adjustable gastric banding as a salvage solution for failed gastric bypass.

Background: The Roux-en-Y gastric bypass (RYGB) has long been considered the gold standard of weight loss procedures. However, there is limited evidence on revisional options with both minimal risk and long-term weight loss results.

Objective: To examine percent excess weight loss, change in body mass index (BMI), and complications in patients who underwent laparoscopic adjustable gastric banding (LAGB) over prior RYGB.

One-year readmission rates at a high volume bariatric surgery center: laparoscopic adjustable gastric banding, laparoscopic gastric bypass, and vertical banded gastroplasty-Roux-en-Y gastric bypass.

Background: An increasing importance has been placed on a bariatric program's readmission rates. Despite the importance of such data, there have been few studies that document 1-year readmission rates. There have been even fewer studies that delineate the causes of readmission.

Bariatric surgery: low mortality at a high-volume center.

Background: The American Society of Bariatric Surgery has initiated a Bariatric Surgery Center of Excellence Program and the American College of Surgeons has followed with their Bariatric Surgery Center Network Accreditation Program. These programs postulate that concentration of weight loss operations in high-volume centers will decrease surgical mortality and improve outcomes.

Methods: The purpose of this study was to calculate the in-hospital mortality for bariatric operations accomplished at the highest volume bariatric surgery center in the state of New Jersey.

Short-term outcomes for super-super obese (BMI > or =60 kg/m2) patients undergoing weight loss surgery at a high-volume bariatric surgery center: laparoscopic adjustable gastric banding, laparoscopic gastric bypass, and open tubular gastric bypass.

Background: We previously reported significantly longer operating room times and a trend toward increased complications and mortality in the super-super obese (body mass index [BMI] > or =60 kg/m(2)) early in our experience with laparoscopic Roux-en-Y gastric bypass. The goal of this study was to re-examine the short-term outcomes for super-super obese patients undergoing weight loss surgery at our high-volume bariatric surgery center well beyond our learning curve.

Methods: The records for all patients who had undergone weight loss surgery at Hackensack University Medical Center from 2002 to June 2006 were harvested from the hospital's electronic medical database.

30-day readmission rates at a high volume bariatric surgery center: laparoscopic adjustable gastric banding, laparoscopic gastric bypass, and vertical banded gastroplasty-Roux-en-Y gastric bypass.

Background: Recent studies suggest that weight loss operations may actually increase the costs to society due to increased hospital readmission rates. The purpose of this study was to determine the 30-day readmission rates following bariatric operations at a high volume bariatric surgery program.

Methods: Records for all patients undergoing bariatric operations during a 3-year period were harvested from the hospital electronic medical database.

Patient characteristics impacting excess weight loss following laparoscopic adjustable gastric banding.

Background: Weight loss is more variable after laparoscopic adjustable gastric banding (LAGB) than after gastric bypass. Subgroup analysis of patients may offer insight into this variability. The aim of our study was to identify preoperative factors that predict outcome.

The learning curve measured by operating times for laparoscopic and open gastric bypass: roles of surgeon's experience, institutional experience, body mass index and fellowship training.

Background: Surgeons must overcome a substantial learning curve before mastering laparoscopic Roux-en-Y gastric bypass (LRYGBP). This learning curve can be defined in terms of mortality, morbidity or length of surgery. The aim of this study was to compare the learning curves in terms of surgical time for the first 3 surgeons performing LRYGBP in our hospital with the length of surgery for open gastric bypass (CONTROLS).

Predictors of prolonged hospital stay following open and laparoscopic gastric bypass for morbid obesity: body mass index, length of surgery, sleep apnea, asthma, and the metabolic syndrome.

Background: The number of weight reduction operations performed for type II and type III obesity is rapidly escalating. Risk of surgery has been infrequently stratified for patient subgroups. The purpose of this study was to identify patient characteristics that increased the odds of a prolonged hospital length of stay (LOS) following open or laparoscopic Roux-en-Y gastric bypass (RYGBP).

Impact of fellowship training on the learning curve for laparoscopic gastric bypass.

Background: We have previously shown that the learning curve for laparoscopic Roux-en-Y gastric bypass (LRYGBP) is approximately 75 cases. Patients have worse outcomes during the learning curve. Our aim was to evaluate the impact of fellowship training on outcomes during a surgeon's early experience with LRYGBP.

Short-term results of laparoscopic gastric bypass in patients with BMI > or = 60.

Background: Laparoscopic Roux-en-Y gastric bypass (LRYGBP) has been shown to be safe and effective. Little information is available about the subgroup of patients with BMI > or = 60. The goal of this study was to evaluate the feasibility and safety of LRYGBP for patients with BMI > or = 60.
