Filter by:Total body weight loss (TBWL) after bariatric endoscopy (BE) is variable. Gastric emptying may be normal, rapid or delayed in patients with obesity and be a factor in variable BE outcomes. Gastric myoelectrical activity (GMA) reflects gastric pacemaker activity which controls gastric contractions. The non-invasive electrogastrogram(EGG) uses standard electrodes positioned on the abdominal surface to record GMA. The investigators postulate that GMA patterns recorded with EGG will reflect subgroups in regards to stomach electrical physiology in obesity and that these subgroups will be useful in selecting patients for various BE procedures to maximize success of the procedures.
This is a prospective collection of data from adult patients who have had an endoscopic metabolic and bariatric endoscopy procedure (EMBT) for primary or revision surgical procedures for obesity.
The study objective is to demonstrate the equivalence of the Atmo Motility Gas Capsule System with the predicate SmartPill in measuring gastric emptying time and colonic transit time through examination of device agreement.
The goal of this study is to explore the pathophysiology of diabetic gastroparesis by conducting an exploratory cohort study. Participants will be type 1 diabetes patients with and without gastroparesis. Investigators will investigate - Differences in nervefiber density and morphology - Cellular and transcriptional changes and indices of glucosemetabolism between groups
In the proposed study, we will be evaluating the effects of pylorus sparing antral myotomy alone, without concomitant endoscopic sleeve gastroplasty (ESG), on weight loss for subjects undergoing the procedure with a history of obesity. This is referred to as Bariatric Endoscopic Antral Myotomy (BEAM). To better understand treatment effects, we will track weight loss, gastric emptying with gastric emptying breath tests (GEBT), and gut hormones (i.e. ghrelin). This pilot, single-center, randomized, controlled, clinical study aims to assess the safety, tolerability, and short-term efficacy of BEAM, in addition to exploring its impact on gastric physiology. This will also provide data that may be used in designing a larger clinical trial that could be submitted for NIH grant funding.
Gastric myotomy has been performed for several years as a means of addressing chronic stenosis after sleeve gastrectomy and treating gastroparesis. The Pylorus Sparing Antral Myotomy (PSAM) technique has the opposite effect by leaving the pylorus intact and extending the myotomy proximally to the distal gastric body. PSAM was initially combined with ESG and shown to delay gastric emptying and provide greater weight loss without impacting tolerability (GCSI score) or the safety profile of the procedure (2 DDW GEM abstracts). PSAM has not been evaluated alone, without concomitant ESG. Since delayed gastric emptying alone is known to promote weight loss, it is thought that PSAM alone (without ESG) may provide similar efficacy, while reducing procedure time and adverse events. There have been no clinical studies that investigate the efficacy of PSAM independent of ESG. This pilot study aims to address this lack of information by evaluating the safety, tolerability, and short-term efficacy of PSAM, in addition to exploring its impact on gastric physiology. This will also provide data that may be used in designing a larger clinical trial.
The goal of this clinical trial (REMBRANDT) is to evaluate the effectiveness of adding an extra connection (i.e. 'Braun anastomosis') after standard reconstruction in pancreatic head resection in reducing the incidence of delayed gastric emptying.
The goal of this pilot prospective cohort study is to examine the reproducibility of gastric volume and emptying as measured by gastric ultrasound and its correlation to a gold-standard test for gastric emptying in the perioperative period in pediatric patients. The main questions it aims to answer are: - What is the reliability (inter-rater variability between expert and novice assessors, and intra-rater variability) of a) the gastric antral cross-sectional area (CSA) and b) gastric volume using the Perlas US qualitative grading assessment, measured by using an ultrasound device in pediatric patients undergoing general anesthesia for elective surgery? - What is the correlation between ultrasound assessment of gastric emptying by the antral-CSA and gastric emptying determined by the acetaminophen absorption test (AAT), the gold standard? The study will include two cohorts. Cohort assignment will be based on age and anesthesia induction plan. Subjects >7yrs of age and expected to get an IV induction will be assigned to Cohort #1. Subjects <7yrs of age and not expected to get an IV induction will be assigned to Cohort #2. - Cohort 1 will include abdominal ultrasound for gastric assessment AND the acetaminophen absorption test which includes administering enteral acetaminophen (tylenol) with 6 oz of water and drawing of blood samples through a peripheral intravenous line. - Cohort 2 will include subjects for whom a peripheral intravenous line placement is not part of routine pre-operative care. Procedures for Cohort 2 will include abdominal ultrasound only in the pre-op area (no tylenol). This cohort is included to examine the reliability of measurements across age groups.
In recent years, with the continuous development of minimally invasive techniques, laparoscopic pancreatic surgery has also been widely used. Although the postoperative mortality rate of laparoscopic pancreatic surgery has been decreasing as the technology continues to improve and mature, the complication rate reported varies widely among centers.The definition and grading criteria of ISGPS on postoperative complications of pancreatic surgery are mostly proposed based on open pancreatic surgery, and most of the data of the later related studies are also for open pancreatic surgery, while the applicability of the definition and grading criteria in laparoscopic pancreatic surgery is still lacking in systematic The study The main purpose of this study is to investigate the applicability of the ISGPS definition and grading criteria for pancreatic fistula, postoperative bleeding and delayed gastric emptying in laparoscopic pancreatic surgery.
This prospective observational randomized study aims to determine energy, protein intake and gastrointestinal tolerance while using enteral nutrition formulas with very high protein content and enteral nutrition formulas with normal protein content. - Differences regarding achieving protein and calorie daily targets when using enteral nutrition formulas with different protein content - Differences regarding residual gastric volume when using enteral nutrition formulas with different protein content - Differences regarding body composition when using enteral nutrition formulas with different protein content
