Which factor after GI surgery is associated with prior gastric resection?

• A. Prior gastric resection
• B. Bowel length
• C. Residual disease in the remaining intestine
• D. Absence of colon and/or ileocecal valve

Answer: (A)

A history of gastric resection is the factor that directly ties into what happens after this specific surgery. Removing part of the stomach changes gastric physiology—acid production drops and intrinsic factor production can be reduced—so the body’s ability to absorb certain nutrients (notably iron and vitamin B12) is affected. It can also alter gastric emptying and predispose to dumping, all of which influence postoperative nutrition needs and risks. Among the listed factors, the fact that a gastric resection occurred is the one that specifically reflects the prior surgical event and its downstream effects on digestion and nutrient absorption, whereas the other factors describe the remaining bowel or disease burden that aren’t as directly linked to having had stomach surgery.
