Gastric amyloidosis with massive bleeding requiring emergency surgery
Journal of Gastroenterology
|September 28, 2001
Summary
This case study highlights a life-saving emergency surgery for massive gastric bleeding caused by systemic amyloidosis. Despite surgical success, the patient later died from arrhythmia, underscoring the complexities of managing this rare condition.
Area of Science:
- Gastroenterology
- Hematology
- Pathology
Background:
- Systemic amyloidosis is a rare condition characterized by amyloid protein deposition in various organs.
- Gastrointestinal involvement, particularly gastric ulcers leading to hemorrhage, is an uncommon but serious complication.
Observation:
- A 66-year-old woman presented with anemia and macroglossia, indicative of systemic amyloidosis.
- Endoscopy revealed a large, hemorrhagic gastric ulcer, confirmed as amyloidosis via biopsy.
- The patient experienced shock due to massive bleeding, necessitating emergency surgery.
Findings:
- Histological examination confirmed extensive amyloid deposition in the stomach (submucosa to muscularis propria), liver, and small intestine.
- The amyloid type was identified as AL-type, negative for AA antibodies and resistant to K2MO4 treatment.
- Total gastrectomy was required due to the extensive submucosal disease, and the patient initially recovered.
Implications:
- This case underscores the critical, life-saving role of emergency surgery in managing severe gastrointestinal bleeding secondary to systemic amyloidosis.
- The rarity of gastrointestinal surgery in amyloidosis patients (41 reported cases) emphasizes the need for awareness and specialized management strategies.
- Despite surgical intervention, the patient's subsequent death from arrhythmia highlights the systemic and potentially fatal nature of advanced amyloidosis.
