BACKGROUND Increasing numbers of laparoscopic surgeons are performing laparoscopic Roux-en-Y gastric bypass (LGB). Our aim was to determine the length of the learning curve for a skilled laparoscopic surgeon. METHODS The study population consisted of the first 225 consecutive LGB procedures attempted by one laparoscopic surgeon (HJS). Outcome parameters(More)
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. METHODS The study population consisted of(More)
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(More)
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(More)
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. METHODS Demographics, co-morbid conditions and follow-up weight were collected for our(More)
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(More)
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. METHODS The study consisted of the first 300 attempted LRYGBPs(More)
