Filter by:GERD is a prevalent condition worldwide, estimated to be around 20-30 % in North America. Obesity is rapidly increasing with an estimated prevalence of 66% in the adult population in the United States. Presently, bariatric interventions are the only sustainable method to address morbid obesity and its resulting comorbidities. One of the most common restrictive surgeries includes laparoscopic sleeve gastrectomy (LSG). Although very effective for treating obesity, some of these surgeries might cause deleterious effects regarding GERD, due to anatomical modifications. Refractory GERD is defined by lack of symptom control on maximum dose of PPI therapy. Cardia Band Ligation Anti-reflux (CLEAR) procedure utilizes multiple band ligations at the cardia in a 270-degree fashion, resulting in tissue necrosis and scar formation, narrowing the GE junction and enhancing the flap valve system. The investigators hypothesized that CLEAR can be a safe and efficient intervention to improve post bariatric GERD.
In Switzerland, the most commonly performed bariatric procedure is the proximal Roux-en-y gastric Bypass surgery. Since marginal ulceration is a known complication after this Operation, a Proton pump Inhibitor (PPI) prophylaxis is prescribed postoperatively. Bariatric surgery may have an impact on the absorption and consequently on the efficacy of drugs. There are only very little data on the pharmacokinetics of PPIs following PRYGB. The aim of this study is to analyze the serum concentration of dexlansoprazole preoperative and after PRYGB surgery in patients taking PPI prophylaxis and to examine the incidence of marginal ulcers postoperatively in the same population.
The Sleeve Gastrectomy (SG) is a bariatric surgery procedure performed by laparoscopic booming in recent years. This is an effective intervention on weight loss over the long term with few early postoperative complications and low morbidity in the long term. Obesity is considered as a risk factor for hernia full after surgery by laparoscopy with a relative risk of 29% in connection with cholecystectomy. Several series showed a rupture rate on trocar from 0 to 0.7%, but each time with a clinical evaluation. Recently, it was shown eventrations rate between 26 and 38% under the Roux-en-Y gastric bypass with a rupture rate increased on epigastric trocar. The assessment in the context of this series was ultrasound. Recent data suggest that the absence of closure of the epigastric trocar of 12mm through an SG of first intention was associated with a hernia rate of 17% with a scannographic evaluation. Also, recently, Tabone suggests that the systematic closure of the epigastric trocar site would not be as effective as lateralize inserting the trocar from the white line of the abdomen. Change the positioning of this trocar induce an additional difficulty in handling instruments for the realization of the SG with an désaxassion instruments, a conflict between the instruments for the realization of the SG and the optical laparoscopy.
