NCT07464223
This study evaluates changes in pancreatic fat and recovery of pancreatic function in obese patients undergoing laparoscopic sleeve gastrectomy (LSG), a weight-loss surgery. Obesity can cause fat to accumulate in the pancreas, which may impair insulin production and lead to type 2 diabetes. This study uses magnetic resonance imaging (MRI) to measure pancreatic fat before and after surgery to understand how weight loss affects pancreatic function. About 50 obese patients (BMI \> 32 kg/m²) aged 16-60 years who are scheduled for LSG will be enrolled. Participants will undergo MRI scans of the pancreas and blood tests before surgery and at 1, 3, and 6 months after surgery. The MRI uses a safe, non-invasive technique called Dixon imaging to measure fat content in different parts of the pancreas (head, body, and tail). Blood tests will measure fasting glucose, insulin, C-peptide, and HbA1c to assess pancreatic function. The study aims to determine whether reduction in pancreatic fat after weight-loss surgery is associated with improved insulin secretion and reduced insulin resistance. This information may help doctors better understand how bariatric surgery improves metabolic health and guide postoperative patient management. Participation involves no additional risk beyond routine clinical care. All MRI scans and blood tests are part of standard postoperative monitoring for bariatric surgery patients.

The SPES clinical study aims to evaluate the relationship between pancreatic fat accumulation (pancreatic steatosis) and metabolic health. Pancreatic steatosis has been linked to conditions like type 2 diabetes (T2D) and metabolic syndrome, but the underlying mechanisms and its impact on beta-cell function remain poorly understood. The primary goal of this study is to develop a quantitative ultrasound elastography score to measure the degree of pancreatic steatosis and explore how this relates to pancreatic beta-cell function and key factors associated with the development of type 2 diabetes and metabolic syndrome. A secondary goal is to categorize participants into four risk classes for type 2 diabetes based on their metabolic profiles and correlate these classes with the degree of pancreatic steatosis. This may provide insights into individual risk stratification for T2D and related complications. The study will enroll 100 participants, aged 18 to 80, attending the Endoscopic Ultrasound Unit at the Fondazione Policlinico Universitario Agostino Gemelli in Rome. Participants will undergo endoscopic ultrasound for various clinical reasons, excluding those with pancreatic tumors, cystic fibrosis, or insulin-treated diabetes. Key inclusion criteria include controlled blood glucose levels (HbA1c \< 10% or fasting glucose \< 250 mg/dL) and the ability to understand and provide informed consent. The study is interventional but does not involve drugs or medical devices. Participants will attend a visit where medical history, physical measurements (e.g., BMI, waist circumference, blood pressure), glucose tolerance tests, and blood work will be collected. This comprehensive approach aims to better understand the metabolic implications of pancreatic steatosis and its role in type 2 diabetes development. The study will last 24 months, including the enrollment period. Findings may contribute to improved risk stratification, prevention, and management strategies for type 2 diabetes and related conditions.

Pancreatic cancer is the fifth leading cause of cancer mortality in Hong Kong and the seventh leading cause of cancer mortality worldwide. In 2020, approximately 496000 new cases of pancreatic cancers were diagnosed globally . Pancreatic cancer is a highly fatal cancer with a case-fatality rate of 94.0% globally. In Hong Kong, both the incidence and mortality of pancreatic cancer have increased over the past decade. Due to the deep-seated location of pancreas, it is difficult to diagnose pancreatic cancer at an early stage, which in turn leads to delays in cancer treatment and poorer survival. Despite advances in oncologic treatment, the 5-year survival rate of metastatic pancreatic cancer remains poor (\~2.9%). As such, there has been growing interest to improve pancreatic cancer prevention and survival by: 1. reduction of modifiable risk factors (eg, cigarette smoking, obesity, diabetes), 2. screening for early detection of high-risk pre-malignant lesions in selected high-risks patients with strong family history of pancreatic cancer and/or certain germline mutations of pancreatic cancer susceptibility genes (eg, BRCA1, BRAC2, DNA mismatch repair genes in Lynch Syndrome, etc) by magnetic resonance imaging (MRI) or endoscopic ultrasound (EUS), and 3. surveillance of pre-malignant precursor lesions such as mucinous pancreatic cystic neoplasms (PCN) by imaging and/or EUS to identify high-risk neoplastic progression indicated for surgical resection.
