Overview
Emergency surgery may be needed to control bleeding in about 10% to 25% of patients in whom nonoperative management is unsuccessful or unavailable.
Surgery
Emergency surgery may be needed to control bleeding in about 10% to 25% of patients in whom nonoperative management is unsuccessful or unavailable.[1][2][3][4]
Indications
Indications for emergent surgery include:
- Hemodynamic instability with active bleeding
- Recurrent bleeding
- Transfusion requirement of greater than 6 units of packed red blood cells (PRBCs) in 24 hours with active bleeding.
- Patients requiring ten or more units of PRBCs in 24 hours have a significantly greater mortality than patients who receive less than 10 units of blood (45% vs 7%).
Surgical Options
- Surgical options include segmental resection and subtotal colectomy.
- If emergency surgery is required, definitive localization of the bleeding site is ideal, because segmental colonic resection is preferred.
- However, segmental resection should be avoided unless the source is definitely identified because this operation is associated with high rebleeding, morbidity, and mortality rates.
- If the bleed cannot be localized, a subtotal colectomy is the recommended procedure.
- Bleeding caused by tumors should be resected with the appropriate oncologic procedure to ensure adequate margins and lymph nodes in the specimen.
- Intraoperative proctoscopy may help to exclude bleeding from a rectal source in patients undergoing subtotal colectomy
Complications
- Both emergency segmental resection and subtotal colectomy are associated with high morbidity and mortality and should, therefore, be considered as a final treatment option
- Subtotal colectomy is associated with the highest complication rates, with morbidity rates of 20% to 60% and mortality rates of 15% 17%.
