Summary
Massive small intestine removal (at least 2/3) causes severe metabolic issues and malabsorption, leading to steatorrhoea and diarrhea. Adaptation mechanisms and specific feeding strategies are crucial for survival after extensive intestinal resection.
Area of Science:
- Gastroenterology
- Surgical Physiology
Context:
- Physiology of bile salt entero-hepatic circulation.
- Triglyceride absorption mechanisms.
- Intestinal nutrient absorption sites.
Purpose:
- To discuss the consequences of extensive small intestine resection.
- To describe compensatory mechanisms for intestinal adaptation.
- To outline nutritional management post-resection.
Summary:
- Extensive small intestine removal (≥2/3) leads to life-threatening metabolic disturbances due to rapid transit.
- Malabsorption of lipids causes steatorrhoea and electrolyte-rich diarrhea.
- Anatomical and functional adaptations of the intestinal mucosa can prolong transit time.
Impact:
- Highlights the critical role of the small intestine in nutrient and fluid absorption.
- Informs surgical strategies and post-operative care for patients with short bowel syndrome.
- Emphasizes the necessity of parenteral nutrition followed by oral feeding during adaptation.
