Evaluation of Patients Who Underwent Sleeve Gastrectomy With Jejunoileal Anastomosis for the Treatment...

Sleeve Gastrectomy With Jejunoileal Anastomosis

Laparoscopic sleeve gastrectomy operations performed for morbid obesity are among the most common methods in the world. Gastric or intestinal bypass surgery with or without sleeve gastrectomy is thought to be more effective in controlling both weight loss and metabolic diseases. For this purpose, Roux-en-y gastric bypass, transit bipartition, duodenal switch, jejunoileal bypass are performed. The aim of this study was to evaluate the effects of jejunoileal bypass surgery on weight loss and metabolic diseases in patients with sleeve gastrectomy.

Body Mass Index and Obesity Surgery Mortality Risk Score in Perioperative Complications of Laparoscopic...

Perioperative ComplicationLaparascopic Sleeve Gastrectomy5 more

The term obesity is defined as body mass index (BMI) 30 and over, and morbid obesity is considered as BMI greater than 40 (1).Its incidence in the general population is approximately 20% according to Organisation for data of Economic Co-operation and Development (OECD) countries and unfortunately, it is increasing worldwide (2). Obesity should not be thought ofas a single disorderasit is related tomany disorders like hypertension, diabetes, obstructive sleep apnea, cardiovascular diseases, and increased risk of malignancies (1).For years people have struggled with obesitywithboth metabolic and physical problems. Surgical treatment is the most effective long-term therapeutic treatment in current and modern medicine of obesity and obesity-related diseases as the last resort.(3-5). Roux-en-y gastrojejunostomy is the method that has been applied for many years and there isconsensus on its effect.However, in recent years, laparoscopic sleeve gastrectomy (LSG) has an increasing number of procedures with a short learning curve and it is the most performed surgical technique all over the world and also in Turkey (2,6). Unfortunately, like any surgical procedure, this surgery has its own complications.Although being performed frequently increases the experience of surgeons, this situation cannot reduce the risk of complications of surgery to zero. In morbid obesity patients, the risk of any complications in all surgical procedures is higher than withother patients who were not morbidly obese. Due to these complications, prolonged hospital stays, increased reapplications to the hospital, reoperations and deaths can result(5,7). Despite both an increased risk of complications according to obesity and the risk of specific complications due to sleeve gastrectomy, laparoscopic sleeve gastrectomy is associated with acceptable postoperative morbidity and mortality rates (8). Various classifications have been described in the literature for complications after surgery.In one of these classifications, according to Clavien-Dindo (CD) Classification, complications are divided into two groups as major and minor. (1, 9)(Table 1). This classification can be applied to bariatric and metabolic surgeries as withall surgery types. Especially major complications in this classification are life-threatening situations and their early detection is important (8). In fact, surgeons do not want to encounter mortality in any of their patients. In this respect, DeMaria et al. developed an easily applicable mortality risk scoring system, which is consisted of five items (age ≥45 years, male sex, body mass index (BMI) ≥ 50 kg / m2, arterial hypertension, and risk factors for pulmonary thromboembolism) and can be used for the pre-operative determination of risky patients in obesity surgery(Obesity Surgery Mortality Risk Score; OR-MRS) (8,10,11). In this study, it is aimed to determine the perioperative complications seen in the laparoscopic sleeve gastrectomy patients that we performed in our clinic without being discharged from the hospital and to evaluate the treatment processes of the complications under literature. In addition, whether the OS-MRS risk assessment scale and BMI had a role indetermining perioperative complications before discharge was investigated.

Outpatient Bariatric Surgery

ObesityMorbid

This study first presents the organizational path and the health interventions included in the care episode for outpatient bariatric surgery, as compared to the health interventions usually performed in the care episode for bariatric surgery (including a conventional hospitalization with at least one-night inpatient). Then, the study aims to estimate and to compare the costs of bariatric surgery inpatient care episode to the costs of outpatient care episode, and also to evaluate the postoperative medical consequences.

Changes of Oral and Intestinal Microbiota After Bariatric Surgery

Morbid Obesity

Purpose The aim of this study was to analyze the changes of microbiota among patients undergoing LSG or LRYGB on two levels of gastrointestinal tract (using oral swab and stool sample). We compared samples from patients before and after bariatric operation. Materials and methods This prospective cohort study was conducted in one academic, teaching hospital. The recommendations of the Metabolic and Bariatric Surgery Section of the Polish Surgical Society were used as indication for surgery, that is: Body Mass Index (BMI) ≥35 kg/m2 with obesity-related comorbidities or BMI ≥40 kg/m2. Analysis and endpoints Primary endpoint was to determine the difference in microbiota present in oral cavity and large intestine between patients before and after bariatric surgery. Secondary endpoint was to compare the difference in microbiota changes between patients undergoing LSG and LRYGB

Severe Obesity and Eating Habits (OSCAR)

Eating DisordersSevere Obesity

In anorexia nervosa,the eating disorder (ED) is the cause of thinness. In severe obesity, the overweight is a symptom. This symptom, however, is only the consequence of possibly deregulated eating behavior. The literature, focusus a specified ED of DSM-V: Binge Eating Disorder (BED) or Binge Eating, whom estimated prevalence in the severely obese population varies from 1.4 to 49% depending on the studies. The other ED, called unspecified ED (or EDNOS for Eating Disorder Non Otherwise Specified in the English literature), are much less known. The main objective of this study is to assess the prevalence rate of unspecified ED (EDNOS or "non-BED ED") in subjects with severe obesity (BMI> 35) consulting for medical or surgical management in a General Hospital Center CSO (Specialized Obesity Center) using an adapted version of the QEWP-R, called the QEWP-RA.

The Role of Extended Antral Resection on Weight Loss and Metabolic Response After Sleeve Gastrectomy...

Bariatric Surgery CandidateObesity1 more

Aim: The impact of extended antral resection (AR) after laparoscopic sleeve gastrectomy (LSG) on weight loss changes and metabolic response is still not clearly elucidated with conflicting results. The investigator's retrospective cohort study aimed to determine whether AR is superior to antral preservation (AP) regarding weight loss and resolution of co-morbidities. Methods: Patients were divided into two groups according to the distance of gastric division as AR group (2cm from pylorus) and AP group (6cm from pylorus). Postoperative excess weight loss percentile (%EWL) and total body weight loss percentiles (%TBWL) at the end of first, 6th and 12 months were compared. Secondly, metabolic parameters and complications were compared.

Endotoxin and Intestinal Flora Before and After Gastric Bypass or Banding in Diabetics

ObesityMorbid3 more

This research project is designed to investigate endotoxin (a toxin present in the wall of certain kinds of bacteria) levels and the type of bacteria present in the intestine before and after Roux-en-Y gastric bypass or gastric banding surgery in patients that meet the classification for morbid obesity (body mass index >40 kg/m2) and type 2 diabetes. It is known that the type of bacteria present in the intestines of normal weight and obese individuals are different, and it is also known that people with obesity and type 2 diabetes have higher levels of endotoxin. It has been shown that the bacteria change over the long run after Roux-en-Y gastric bypass surgery, but the short-term effects are not known and the endotoxin levels after this procedure have never been studied.

Glucose Homeostasis Pre and Post Bariatric Surgery

Morbid Obesity

The investigators wish to study the effects of three forms of bariatric surgery: Roux-en-Y gastric bypass, Sleeve Gastrectomy, and Gastric Banding. The surgery is not part of the clinical trial. If your insurance does not cover the procedure, then you are responsible for payment of the surgical process. We are doing pre and post surgery testing to provide a better understanding of the effect of bariatric surgery-induced weight loss on metabolic function.

Energy Expenditure and Gastric Bypass Surgery Study

Morbid Obesity

The aim of this study is to assess whether the energy you burn daily increases after you have bariatric surgery. Until now, there hasn't been an effective way of measuring all activity on a daily basis. Physical Activity Monitoring System (PAMS) has been created just for this purpose. PAMS is a garment that can be worn under your clothes, that records body position and movement through space. We will use the PAMS along with special water to measure your total daily energy expenditure right before surgery, and again 6 months and 24 months after surgery. Study subjects will be initially recruited from OHSU IRB-Approved advertisements. Interested study subjects will be screened through an informal telephone interview. If there are no health conditions that exclude participation, subjects will be asked to give IRB-approved consent. Subjects will be consenting to undergo three 18 day phases. Each phase will consist of 15 daily visits to the Clinical & Translational Research Center (CTRC), and 3 full day and nights in the CTRC.
