“Is bowel resection surgery dangerous?”

All surgeries carry risks.

Every surgery is dangerous. The worst complication with any bowel resection is anastomotic leak, but the risk for this complication depends largely on the type of bowel resection, the acuity of the surgery, comorbidities, and overall health. Other, more common acute complications are bleeding, infection, and ileus. Long-term complications include small bowel obstruction (at least 10% lifetime risk), hernia, poor vitamin absorption, diarrhea, short gut syndrome, and difficulty with subsequent abdominal procedures.

Generally no, but there are risks. The dreaded complication of bowel surgery is re-connecting the intestines (called an anastomosis). A leak from the connection is possible and can lead you to become very ill. The risk of that is very low, and varies based on your medical history, reason for surgery, amount of inflammation, etc. Surgeons rarely recommend bowel resection unless absolutely indicated, so it may ultimately be more dangerous for you not to have surgery.

No, new developments in technique have made it very safe.
