Gastric resections Flashcards
Jejunoileal anastomosis
Jejunum attached to iluem, resulting in transient gastric acid hypersecretion and impaired digestion
jejunocolic anastomosis
Jejunum attached to colon - b12 deficiency, steatorrhoea, KEDA deficiency, choleretic diarhoea, bile salt reabsorption impaired
Jejunostomy
significant nutrient and fluid losses, magnesium deficiency, b12 deficiency, impaired bile salt reabsorption
Whipple procedure
Pancreaticduodenectomy, remove the head of the pancreas, duodenum, the gallbladder and the bile duct
Hartmanns procedure
sigmoid colon and upper rectum removed and colostomy formed
Early symptoms of resections
Dumping syndrome, small stomach syndrome, diarrhoea, bile vomiting,
Vagotomy
Excision of vegus nerves typically to reduce gastric acid secretion to prevent further development of peptic ulcers
Pyloroplasty
Widen pyloric sphincter to allow food to enter duodenum
Long term consequences of gastrectomy
Weight loss and undernutrition
Malabsorption
Anaemias
In cases of severe steatorrhoea, what could you substitute fat for?
glucose polymers or MCTs
Medical management of malabsorption secondary to gastrectomy
anti-diarrhoeal, bile acid binders, pancreatic enzyme replacement
Disturbances following disturbed gastric function
Dumping syndrome increased intestinal motility reduced pancreatic enzymes reduced IF secretion inadequate mixing of food abolishment of normal pH gradient reduced absorption
