Prospective Observational Study on the Utility of Continuous Glucose Monitoring for the Diagnosis of Dumping Syndrome After Esophagectomy

Background:

Dumping syndrome is a common complication for patients who have undergone surgery for esophageal cancer. It occurs when food moves too quickly from the stomach (or the reconstructed gastric tube) into the small intestine. This rapid movement causes various symptoms such as bloating, abdominal pain, dizziness, rapid heartbeat, and sweating. Sometimes, it leads to "late dumping," where blood sugar levels drop significantly, causing tremors, cold sweats, and fatigue. Currently, there is no standardized tool to easily diagnose this condition after esophagectomy.

Purpose of the Study:

The objective of this study is to evaluate the effectiveness of Continuous Glucose Monitoring (CGM) in diagnosing dumping syndrome. CGM is a small, wearable sensor that tracks glucose levels in real-time. The investigators aim to determine whether CGM can serve as a valuable tool for the early detection of dumping syndrome in patients who have undergone esophagectomy.
