Filter by:The investigators hypothesize that cefazolin perfusion to subcutaneous adipose tissue is reduced in morbidly obese patients. The primary objective of this exploratory pilot study is therefore to investigate target site (subcutaneous adipose tissue) penetration of cefazolin in morbidly obese patients and non-obese patients. The investigators aim to examine whether and how cefazolin plasma concentrations are predictive of subcutaneous (target) cefazolin concentrations. Possible factors of influence on the distribution of cefazolin (tissue perfusion, body weight, distribution of adipose tissue, other) will be identified.
The investigators wish to standardise and optimise perioperative care for consecutive patients undergoing laparoscopic sleeve gastrectomy for weight loss. The investigators will compare patients under a standardised perioperative care program to patients who undergo routine perioperative in our hospital and determine whether patients who had optimised perioperative care went home earlier and had fewer complications.
The study must be performed in 100 patients suffering from morbid obesity, the procedure will be performed under general anesthesia doing two or three layers of suture to achieves gastric imbrication until transform the stomach to a sleeve. The patients will be followed during the time for 6 month, 1 year, two years and 5 years.
Excess visceral fat is a key factor in the development of metabolic syndrome associated with obesity. After bariatric surgery, patients experience weight loss accompanied by a decrease in the amount of total body fat. It is unclear how the different surgical procedures vary in their effect on the visceral and subcutaneous fat change. Ultrasonography (US) is an effective, efficient method in assessing this metabolically active layer of fat even when compared with gold standard techniques such as computed tomography and magnetic resonance imaging. Only a few studies managed to show the actual decrease in the visceral fat layer after these kinds of surgeries. The aim is to compare by ultrasound evaluation the extent of fat layers reduction after laparoscopic adjustable gastric banding (LAGB), laparoscopic sleeve gastrectomy (LSG) and laparoscopic roux-en-y gastric bypass (LRYGB). The hypothesis is that the sleeve gastrectomy and gastric bypass being not only a restrictive procedure but also a malabsorptive procedure will have the best results in decreasing the amount of visceral fat.
The objective of this prospective randomized clinical study was to compare anesthesia, in morbidly obese patents (BMI >50) who underwent BPD-RYGBP with either sevoflurane or propofol with remifentanyl.
The major problem in the treatment of morbidly obese children is the long term maintenance of the reduced weight. Maintenance-focused interventions have not been studied enough in adolescents with morbid obesity, neither in regard to conservative methods of weight reduction, nor in regard to bariatric surgeries. This study will investigate the effectiveness of an integrative, multi-disciplinary inpatient program for promoting long-term weight maintenance in children with morbid obesity. The program will be studied in two perspectives: as a conservative treatment, as well as an 'envelope' for bariatric surgeries including a pre-operational preparation phase and a post-operational follow-up. The investigators hypothesize that program participants will maintain weight significantly better than the proportion known in the literature.
The purpose of this study is to determine whether or not the length of the biliopancreatic limb of the Roux-en-Y anastamosis plays a critical role in the development of malabsorption after gastric bypass for treatment of severe obesity.
single-center study carried out in order to evaluate in prospective among patients seen or treated in the pediatric endocrinology unit and multidisciplinary management of obesity, the potential number of patients eligible for surgery.
Adequate postoperative analgesia can facilitate recovery following gastric bypass surgery for morbid obesity. The efficacy and safety of intravenous patient - controlled analgesia has been studied, but up to date no data are available concerning the use of thoracic epidural patient-controlled analgesia regarding the use of levobupivacaine combined with morphine in morbidly obese patients. The investigators' aim in this prospective, randomized, double-blinded study was to compare the analgesic effectiveness, the dose requirements and side effects of thoracic epidural patient controlled analgesia 0.1% and 0.2% levobupivacaine combined with a continuous epidural administration of morphine, with or without a loading dose, after open gastric bypass for morbid obesity.
This study is a pilot project to investigate any effect on these markers in conjunction with lifestyle changes / conservative treatment. Useful and significant information in this pilot project is intended to be used as background for further research on this issue in connection with a doctorate. What is the effect of two years of outpatient treatment for lifestyle change for weight markers, waist, BMI, HbA1c, HDL and LDL cholesterol, triglycerides and uric acid in adults with morbid obesity?
