Delayed gastric emptying
Also written as: DGE — Delayed gastric emptying
A common complication following pancreaticoduodenectomy characterized by prolonged gastric dysfunction and feeding intolerance.
Full Definition
Delayed gastric emptying (DGE) is a well-recognized complication occurring in 15-40% of patients after pancreaticoduodenectomy, characterized by prolonged nasogastric decompression, delayed tolerance of solid foods, and symptomatic gastric distension. The International Study Group of Pancreatic Surgery has established standardized grading criteria based on nasogastric tube duration and feeding tolerance. DGE may result from surgical manipulation, vagal nerve injury, electrolyte imbalances, or postoperative inflammation. Management typically involves conservative measures including prokinetic agents, nutritional support, and occasionally endoscopic intervention. The condition usually resolves spontaneously but can significantly impact hospital length of stay and quality of life.
Usage
Usage note: Use ISGPS grading system (A, B, C) when documenting severity; abbreviate as DGE after first mention.
