OBJECTIVE To report the results from one of the eight original U.S. centers performing laparoscopic adjustable silicone gastric banding (LASGB), a new minimally invasive surgical technique for treatment of morbid obesity. SUMMARY BACKGROUND DATA Laparoscopic adjustable silicone gastric banding is under evaluation by the Food & Drug Administration in the(More)
OBJECTIVES Determine the effect of early (days 3-5) or late (days 10-14) tracheostomy on intensive care unit length of stay (ICU LOS), frequency of pneumonia, and mortality, and evidence of short-term or long-term pharyngeal, laryngeal, or tracheal injury in head trauma, non-head trauma, and critically ill nontrauma patients. STUDY DESIGN Randomized,(More)
BACKGROUND Currently, no clinically useful scoring system is available to stratify the mortality risk for patients undergoing gastric bypass (GBP). We propose the obesity surgery mortality risk score as a clinically useful score system to predict the mortality risk for patients undergoing GBP. METHODS Prospectively collected data from 2075 consecutive(More)
OBJECTIVES To determine relationship of intra-abdominal pressure to central obesity and the comorbidity of obesity. DESIGN Non-randomized, prospective. SETTING University hospital, operating room. SUBJECTS Eighty-four anaesthetized consecutive patients prior to gastric bypass for morbid obesity and five non-obese patients before colectomy for(More)
OBJECTIVE To determine the safety and efficacy of laparoscopic Roux-en-Y gastric bypass for the treatment of morbid obesity. SUMMARY BACKGROUND DATA Laparoscopic Roux-en-Y gastric bypass is a new and technically challenging surgical procedure that requires careful study. METHODS The authors attempted total laparoscopic Roux-en-Y gastric bypass in 281(More)
The purpose of this study was to determine whether pre- to postoperative increases in physical activity (PA) are associated with weight loss and health-related quality of life (HRQoL) following bariatric surgery. Participants were 199 Roux-en-Y gastric bypass (RYGB) surgery patients. The International Physical Activity Questionnaire (IPAQ) was used to(More)
It has been suggested that super-super obesity (body mass index [BMI] ≥60 kg/m2) increases the risk of complications after laparoscopic Roux-en-Y gastric bypass (LapRYGB). We hypothesized that a higher BMI does not increase risk the morbidity or mortality rate. Complication rates for patients with a BMI ≥60 kg/m2 were compared to those for patients with a(More)
BACKGROUND Data on the durability of remission of type 2 diabetes mellitus (T2DM) after gastric bypass are limited. Our purpose was to identify the rate of long-term remission of T2DM and the factors associated with durable remission. METHODS A total of 177 patients with T2DM who had undergone Roux-en-Y gastric bypass from 1993 to 2003 had 5-year(More)
OBJECTIVE Evaluate the safety and efficacy of bariatric surgery in older patients. BACKGROUND Because of an increased morbidity in older patients who may not be as active as younger individuals, there remain concerns that they may not tolerate the operation well or lose adequate amounts of weight. METHODS The database of patients who had undergone(More)
BACKGROUND A scoring system for clinical assessment of mortality risk has been previously proposed for bariatric surgery (Demaria EJ, Portenier D, Wolfe L, Surg Obes Relat Dis. 2007;3:34-40.). The Obesity Surgery Mortality Risk Score (OS-MRS) was developed from a single institution experience of 2075 patients. The current study provides multicenter(More)
