Small diameter
Constant blood supply
Hyperchloremic metabolic acidosis
B12 deficiency
Bile salt diarrhea
Fat malasorption
Cancer risk
Colon Able to reach anywhere in abdomen/pelvis
Less likely to have been irradiated
Less risk for metabolic abnormalities
Hyperchloremic metabolic acidosis
Needs mobilization
Diarrhea with removal of ileocolic valve
Cancer risk
