Filter by:Dosing guidelines for liposomal amphotericin B (AmBisome) in (morbidly) obese patients are not available. Subsequently, the pharmacokinetic profile of AmBisome in this specific patient population is still largely unknown. To build a valid pharmacokinetic model, obese patients with a BMI ≥ 40 undergoing endoscopic gastric bypass surgery will receive a single dose of 1 mg/kg or 2 mg/kg AmBisome (besides standard anti-bacterial prophylaxis) and a PK-curve will be drawn. These PK-values can then be compared to the pharmacokinetics of a normal-weight group.
Risk factor of cholelithiasis is rapid weight loss after bariatric surgery and change in the gallbladder function which is secondary to surgery. Many observational studies support this fact, and a high incidence of 28% -71% after gastric bypass surgery (RYGB) was reported in them. According to another publication, the incidence of gallbladder diseases is 5-36% after jejunoileal bypass surgery and 2.8-36% after gastric bypass surgery.
The purpose of this study is to find out more about the safety and effectiveness of the Laparoscopic Greater Curvature Plication (LGCP) procedure in patients with obesity and related problems such as diabetes, hypertension, high cholesterol, mild obstructive sleep apnea, and joint problems. LGCP is a less invasive weight loss surgery procedure than some of the other weight loss surgeries and it is possible that there are fewer risks with this procedure than with the other weight loss surgeries. LGCP is considered an experimental procedure and this study is being done to look at the long-term outcomes.
The purpose of this study is to determine if the application of Boussignac continuous positive airway pressure (CPAP) immediately after extubation improves PaO2 and PaO2/FiO2 ratio in morbidly obese patients undergoing gastric bypass surgery .
This study is a prospective evaluation of the relationship between lean body weight and anti-Xa activity and 5700 International Units (IU) nadroparin 4 hours after subcutaneous administration in morbidly obese patients after bariatric surgery.
the purpose of this study is to determine if 60 meter test done prior to surgery is a predictive in terms of extubation in morbid obese patients undergoing morbid obese surgery.
Morbid obesity is an increasing medical problem in the western countries. It's related to comorbidities as diabetes mellitus, hypertension, OSAS, arthrosis and hypercholesterolemia. The Roux-en-Y Gastric Bypass (RYGB) is an effective surgical therapy for morbidly obese patients. A part of these patients will have disappointing results, and have weight regain on the long term. Some studies show more weight reduction by increasing the biliopancreatic limb in patients with morbid obesity. The objective of this study is to investigate the effect of a restrictive/extended pouch on weight reduction in morbidly obese patients undergoing RYGB-surgery. We hypothesize that the restrictive/extended pouch results in more weight reduction. The study design is a prospective, randomized control trial. The patients will be randomized in 2 groups: a standard RYGB (normal pouch) and restrictive/extended pouch RYGB.
Gastric bypass surgery is the gold standard in bariatric surgery and is a successful method to reduce weight in morbidly obese subjects. Patients qualified for gastric bypass surgery are routinely pre-treated with a low calorie diet in order to reduce liver volume and to facilitate the approach of the gastro-oesophageal junction. Pre-treatment with omega-3 fatty acids has similar effects on liver volume, but a prospective comparison of both treatments has not been performed yet. Morbidly obese patients respond differently to surgical stress, due to a number of factors. First, obesity is associated with a low-grade inflammatory state induced by an increased amount of macrophages in adipose tissue. This state is associated with higher levels of pro-inflammatory cytokines in serum and with a less adequate immune response to infections. Second, obesity is associated with an altered cortisol metabolism possibly related to adrenal insufficiency. This could play an important role in the altered response to surgical stress and postoperative complications in obese subjects. Third, obesity is associated with altered erythrocyte function, including decreased erythrocyte deformability and increased aggregation, factors contributing to an impaired microcirculation. This study has a number of different aims. First, we will compare pre-treatment with the standard low calorie diet with omega-3 fatty acids on liver volume in patients qualified for gastric bypass surgery because of morbid obesity. Second, we will investigate the effect of omega-3 fatty acids on immune function, the low-inflammatory state of adipose tissue, the stress response of obese subjects before and erythrocyte function. Third, we will investigate the effect of gastric bypass surgery by comparing values before surgery with values on the first postoperative day and 6 months after surgery regarding to immunological parameters, stress response and erythrocyte function.
Weight reducing surgery is the only effective therapy for morbid obese patients. Sleeve gastrectomy is a popular choice for bariatric surgery because of less sequela. There is poor knowledge about the nutritional status inpatients after LSG. The aim of our study was to investigate the relationship between dietary intake and weight loss after LSG.
BACKGROUND Unpredicted difficult tracheal intubation (DTI) with Macintosh laryngoscopy occurs frequently in obese patients. We investigated the incidence of DTI using the GlideScope® videolaryngoscope (GVL) with an algorithm based on a pre-operative assessment with the El Ganzouri Risk Index (EGRI). METHODS We prospectively enrolled morbidly obese patients (BMI>40 kg/m2) undergoing abdominal surgery. Patients were scheduled for flexible fibre optic bronchoscopic intubation (FFBI) or GVL intubation if the EGRI score was ≥7 or <7, respectively. The primary outcome was the occurrence of DTI that was defined as Cormack and Lehane (C&L) grades ≥III, Intubation Difficulty Scale (IDS)>5 and modified IDS (mIDS)>5. A numeric rating scale (NRS) was also used. Secondary outcomes included intubation success during the first attempt, the time to Cormack (TTC), the time to intubation (TTI), failure to intubate, oxygen desaturation and difficult ventilation.
