Resting metabolic rate and postabsorptive substrate oxidation in morbidly obese subjects before and after massive weight loss
1996
OBJECTIVE: To investigate the changes of resting metabolic rate (RMR) and postabsorptive oxidation of carbohydrates (CHO), lipids (LIP) and proteins (PT) in morbidly obese subjects after long-term stable massive weight reduction. DESIGN: Longitudinal, intervention study of a bilio-pancreatic by-pass. SUBJECTS: Ten (Four men, six women) obese subjects (BMI: 53.7 ± 2.1 kg/m2, men, nine women) control subjects (BMI: 21.4 ± 1.0 kg/m2). MEASUREMENTS: RMR and substrates oxidation (indirect calorimetry), body composition (bioelectrical impedance), plasma concentrations of glucose, FFA, insulin and thyroid hormones before (T0, prior to surgery), during (T1: 1-3 months, and T2: 9-16 months following…
Revisional bariatric surgery due to failure of the initial technique: 25 years of experience in a specialized Unit of Obesity Surgery in Spain.
2019
Abstract Objectives To evaluate the effectiveness of conversion surgery in a bariatric surgery unit with 25 years of experience. Method Retrospective observational study of patients with type II obesity or higher who were reoperated by means of conversion surgery due to weight regain, residual body mass index (BMI) >35 kg/m2 or Results A total of 112 patients were included, with a mean age of 40.2 years, who initially underwent vertical banded gastroplasty (VBG) (32.1%), gastric banding (GB) (23.2%), Roux-en-Y gastric bypass (RYGB) (21.4%) and sleeve gastrectomy (SG) (23.2%). The conversion techniques, with a median time between the two surgeries of 70 months, included: RYGB, SG, one-anasto…
Surgical treatment of morbid obesity with biliopancreatic diversion and gastric banding: report on an 8-year experience involving 235 cases
2000
Abstract Study aim: Developments have recently been made in bariatric surgery outside the USA. The aim of this retrospective non-randomized study was to report on our experience regarding biliopancreatic diversion (BPD) and non-adjustable gastric banding (GB) in a population of 235 obese patients. Patients and methods: From March 1990 to March 1998, 235 obese patients were operated on, 142 by BDP and 93 by GB, via laparotomy after rigourous selection of the patient population. Results: The mean duration of surgery was 2 h 50 minutes for BPD and 1 h for GB. One postoperative death occurred due to massive pulmonary embolism. Early major complications were frequent in the BPD group ( n = 21) b…
Influences of obesity and weight loss on thyroid hormones. A 3-3.5-year follow-up study on obese subjects with surgical bilio-pancreatic by-pass
1997
The effects of changing body size, energy intake and substrate oxidation on serum T4, FT4, T3, FT3 and TSH were investigated in ten morbidly obese subjects (4 men/6 women; age: 37 ± 6 years; BMI: 53.8 ± 6.5 kg/m2; mean ± SD) who had undergone a surgical bilio-pancreatic by-pass in order to reduce their body weight. The starting value of serum FT3 was inversely related to the BMI (r = -0.63; p < 0.05). After 1-3 months, all the subjects were losing weight and their intake of carbohydrates was almost negligible; at this time a significant reduction of T3 (-14.6%, p < 0.0001), T4 (-19.5%, p < 0.0001), and FT3 (-10.5%, p < 0.001) was observed. Nine to 16 months after surgery, all th…
Surgery for obesity.
2005
PURPOSE OF REVIEW Bariatric surgery today is the only effective therapy for morbid obesity. Commonly performed procedures include adjustable gastric banding and vertical banded gastroplasty, variations of the Roux-en-Y gastric bypass, biliopancreatic diversion or duodenal switch, and mixed procedures. This review discusses key issues in the surgical management of morbid obesity. RECENT FINDINGS The two most common bariatric procedures performed worldwide are laparoscopic adjustable gastric banding and laparoscopic Roux-en-Y gastric bypass. Controversy exists regarding the best surgical procedure. Weight loss decreases according to the procedures performed in following decreasing order: bili…
Biliopancreatic Diversion: early complications
1992
The experience and early complications in 66 morbidly obese patients who underwent biliopancreatic diversion are presented. There was one death, due to a pulmonary embolus (PE) at home on the 15th postoperative day. Postoperative complications occurred in nine patients, consisting of gastric hemorrhage (2), gastric outlet obstruction (2), non-lethal PE (1), deep vein thrombosis (1), wound dehiscence (1), and asymptomatic gastric leak (1). In addition, there were 12 superficial wound infections. Four patients required urgent reoperation for gastric hemorrhage (2), gastric outlet obstruction (1), and wound dehiscence (1). The high complication rate is believed to represent the early part of t…
Adipositaschirurgie bei monogenetisch bedingter Adipositas
2007
Surgical treatment of patients suffering from monogenetic forms of morbid obesity is considered to be the poorest investigated theme in bariatric surgery. This review article presents aspects of genetic disorders in morbid obesity as well as some aspects of surgical treatment in patients with monogenetic forms of morbid obesity (Prader-Willi-Syndrome). Gastric restrictive procedures such as vertical banded gastroplasty or adjustable gastric banding as well as malabsorptive and mix procedures such as biliopancreatic diversion or Roux-en-Y gastric bypass are used for treatment, similar to polygenetic forms of morbid obesity. Until to now there is no evidence-based data because of the small nu…
