NCT07451392
Pylorus-preserving pancreatoduodenectomy (PPPD) is a standard surgical treatment for tumors of the pancreatic head and surrounding areas. However, it is frequently associated with delayed gastric emptying (DGE), a complication that can lead to nausea, vomiting, and prolonged hospital stays. This study is a randomized controlled trial designed to evaluate if a simple intraoperative maneuver (pneumatic balloon dilatation of the pylorus) can reduce the incidence of early postoperative vomiting and DGE. Participants will be randomly assigned to either the intervention group, receiving pyloric dilatation during surgery, or the control group, receiving standard surgery without dilatation. Researchers will monitor postoperative symptoms, gastric emptying function, and overall recovery to determine if this maneuver effectively improves patient outcomes.

Dear Patients, The investigators invite participants to take part in an observational study on gastric emptying rate in individuals with simple obesity. This study has been reviewed and approved by the Ethics Committee of Renji Hospital, affiliated with Shanghai Jiao Tong University School of Medicine. It will be conducted at Renji Hospital and is expected to enroll approximately 100 voluntary participants. Obesity has become a major global public health challenge. In 2020, an estimated 2.2 billion adults-42% of the global adult population-were affected by overweight and obesity. This number is projected to increase to 3.3 billion by 2035, representing 54% of adults worldwide. Obesity significantly compromises health and is associated with a range of metabolic disorders, including insulin resistance, atherogenic dyslipidemia (characterized by elevated triglycerides and low HDL cholesterol), nonalcoholic fatty liver disease (NAFLD), beta-cell dysfunction, prediabetes, and type 2 diabetes, all of which may lead to serious complications, disability, and premature death. Gastric emptying refers to the process by which food moves from the stomach into the duodenum. This process is essential for nutrient absorption and is regulated by gastric motility, as well as by neural and hormonal feedback mechanisms mediated by the interaction of nutrients with the small intestine. The rate of gastric emptying determines the pace at which nutrients reach the intestine and influences the enteral nutrient load. It also plays a bidirectional role in regulating blood glucose levels. Therefore, abnormal gastrointestinal motility may represent an important pathophysiological mechanism underlying insulin resistance and impaired glucose tolerance in obese individuals. To date, most studies on gastric emptying have focused on individuals with diabetes. However, as obesity itself is a major risk factor for metabolic diseases such as type 2 diabetes, further investigation into the distribution patterns of gastric emptying rates in individuals with simple obesity-and its associations with glucose and lipid metabolism, insulin resistance-could provide valuable insights. These insights may support improved diagnosis, risk stratification, and management of obesity-related metabolic disorders, as well as inform the evaluation of weight-loss interventions. The aim of this study is to assess gastric emptying velocity in patients with simple obesity and to explore its relationship with glucose and lipid metabolic indicators. This information sheet is intended to help participants decide whether they are willing to allow the use of their historical medical data for research and analysis. Participation in this study is entirely voluntary, and participants' decision will not affect their access to medical care or any of their rights as patients at Renji Hospital. Please be assured that, should participants choose to participate, the investigators will make every effort to protect their safety, privacy, and legal rights throughout the study, in full compliance with applicable ethical and legal standards. The investigators kindly ask participants to read this notice carefully. If participants have any questions or concerns, they are encouraged to speak with the investigator responsible for explaining the informed consent form.

NCT07140289
This study aims to assess the effect of using Glucagon-like peptide-1 receptor agonists (GLP-1) receptor agonists on gastric emptying on surgical patients and whether specific guidelines need to be established for these patients. GLP-1 receptor agonists are mainly used for the treatment and mitigation of obesity and metabolic syndromes. One of their mechanisms of action is by delaying gastric emptying, hence increasing satiety. However, patients need to abstain from eating for a set amount of time before surgery to reduce the risk of aspiration. Hence patients who use GLP-1 receptor agonists may need more time to abstain eating (nil-per-os). In this study we aim to assess how much time is sufficient before surgery in these specific population of patients.
NCT07100691
This is a multicentre, investigator-blinded, randomised controlled trial evaluating whether the use of oral metoclopramide before surgery can reduce the amount of residual gastric content in patients who are taking glucagon-like peptide-1 receptor agonists (GLP-1 RAs) for weight loss. These medications are known to slow down gastric emptying, which may increase the risk of pulmonary aspiration during anaesthesia. Patients will be randomly assigned to either receive metoclopramide 24 hours before surgery or continue with standard care. The primary outcome will be the presence or absence of residual gastric content on ultrasound before surgery. Secondary outcomes include nausea, vomiting, constipation, and any adverse effects of the medication.
NCT02665923
Ultrasound imaging will be used to evaluate time for gastric emptying in healthy, fasting newborns, and infants following feeding of clear liquids and/or milk (including breast or formula).
NCT06606782
The aim of this prospective, observational study is to evaluate the incidence of residual gastric content in elective surgical patients who adhered to preoperative fasting guidelines and to investigate associated patient-related factors. Ultrasound (USG) has been identified as a valuable tool for assessing residual gastric content, and this study compares its efficacy against traditional questionnaire-based predictions. The study also examines the practicality and accuracy of different gastric volume estimation formulas and evaluates their correlation with aspiration risk. A total of 475 patients were enrolled in the study, of whom 404 completed both the questionnaire and USG examination. All participants were adult patients scheduled for elective surgery, following standard fasting protocols. The ultrasound examination assessed the presence of solid or fluid content in the stomach, and patients were classified according to qualitative Perlas risk scores (Grade 0: Low, Grade 1: Moderate, Grade 2: High risk of aspiration). The questionnaire collected patient-reported factors, such as symptoms of early satiety, history of cholelithiasis, and comorbidities like diabetes or chronic obstructive pulmonary disease (COPD). The primary objective of this study was to evaluate the efficacy of USG in detecting residual gastric content and compare it with questionnaire-based risk predictions. Logistic regression analysis identified early satiety and cholelithiasis as significant predictors of a full stomach and higher aspiration risk. Fasting duration was found to have a protective effect, reducing the likelihood of a full stomach. While many patient characteristics traditionally associated with delayed gastric emptying, such as age and diabetes, did not significantly correlate with the outcomes, early satiety and cholelithiasis proved to be key factors influencing gastric content. In addition, this study explored the performance of several gastric volume estimation formulas, including the Michiko, Bouvet, and Perlas 2019/2020 formulas. The findings indicated significant limitations in these formulas, with many patients being estimated to have negative gastric volumes, particularly by the Michiko and two of Perlas\' formulas. This highlights the inadequacies of current formulas in accurately predicting gastric volume, necessitating further refinement and development of new models that better account for physiological variability. Furthermore, the agreement between questionnaire-based predictions and USG findings was assessed using Cohen's Kappa, which indicated fair agreement (Kappa value = 0.282). This suggests that while the questionnaire can serve as a screening tool to identify patients at risk of aspiration, it cannot replace the accuracy and reliability of USG in clinical practice. Secondary objectives of the study included comparing the time-efficiency and ease of implementation between USG and the questionnaire-based assessments. USG proved to be more time-efficient, taking an average of 2.5 minutes per examination, compared to 3-5 minutes for completing the questionnaire. This speed, combined with its objective nature, underscores USG's value as a practical tool in the preoperative setting. In conclusion, USG was found to be an effective and efficient tool for assessing residual gastric content and predicting aspiration risk, outperforming traditional questionnaire-based assessments. The inadequacy of current gastric volume estimation formulas points to the need for further research to develop more accurate and context-specific assessment tools. Comprehensive preoperative evaluation incorporating USG and patient-reported symptoms may improve patient safety by reducing the risk of aspiration during elective surgery.
NCT06038734
Given the increased prescription of GLP-1 agonists for both diabetes and obesity management and the implications of the proposed delayed gastric emptying in the setting of an anesthetic, it is critical to determine if patients taking GLP-1 agonists have an increased rate of delayed gastric emptying. The purpose of this prospective gastric ultrasound evaluation of pre-operative patients is to determine the incidence of a full stomach despite a standard pre-operative fasting period.

NCT03694509
The aim of the study is to assess the difference in gastric emptying using ultrasound of pregnant patients following a cup of tea with milk or a similar volume of water.
NCT03410147
The objective of this dose-finding and feasibility study is to establish the optimal 13C-octanoate concentration to be used with slowly infused enteral nutrition to perform a prolonged gastric emptying test using the breath test. More specifically, the aim is to discover the 13C-octanoate concentration that induces a steady state hourly 13C-recovery. This would allow to implement the prolonged breath test protocol in a future clinical investigation in critically ill patients.
NCT03525067
The aim of the present prospective study was, first, to verify the correlation between biliary colonization and postoperative infectious complications, and secondarily to asses morbidity and mortality for patients who underwent pancreaticoduodenectomy. The hypothesis is that a proportion of post-operative infections after pancreaticoduodenectomy is due to bacteria that colonize the bile ducts during the preoperative period.
