Abstract
Gastric amyloidosis is a very rare cause of gastric outlet obstruction. Therefore, general treatment recommendations are missing. A 61-year-old man with multiple myeloma and cast-nephropathy with suspected manifestation of amyloidosis was admitted for gastroscopy because of nausea and emesis. Video fluoroscopy demonstrated a gastric outlet obstruction with subtotal stenosis of the pylorus. Gastric amyloidosis (AL-amyloid) was confirmed histologically by deroofingbiopsies which was consistent with the clonotype of the patient’s myeloma. Botox injection was ineffective for control of symptoms. Therefore, endoscopic balloon-dilatation (15 mm to 20 mm) was performed with a long-lasting clinical response of 3 to 6 months.
