Patient Usually Complains Of

Patient presents with progressive postprandial emesis, early satiety, and significant unintentional weight loss. Emesis consists of undigested food particles consumed several hours prior. Denies hematemesis or melena. Reports epigastric fullness and discomfort. Symptoms are consistent with mechanical gastric outlet obstruction secondary to known/suspected antral malignancy.

Clinical Examination Findings

Tenderness to deep palpation in the epigastric region; no rebound or guarding. Bowel sounds: High-pitched/tinkling. Rectal exam: Negative for occult blood.

Treatment Protocol

Immediate management: NPO status, nasogastric tube decompression, and aggressive IV fluid resuscitation with electrolyte correction. Consult Surgical Oncology/Gastroenterology for endoscopic stenting or surgical bypass (gastrojejunostomy) based on nutritional status and performance score. Consider nutritional support (TPN/Enteral) if severe malnutrition is present.
