Gastroparesis is a condition characterized by delayed gastric emptying in the absence of mechanical obstruction. In gastrointestinal oncology, it commonly occurs as a postoperative complication following gastric resection or pancreaticoduodenectomy, or as a side effect of chemotherapy agents. Symptoms include nausea, vomiting, early satiety, and abdominal distension. Editorial note: Distinguish from functional dyspepsia and mechanical obstruction in clinical documentation.
