In a patient with massive lower GI bleed who becomes unstable, which management step is most appropriate?

• A. Exploratory laparotomy
• B. 99mTc RBC scintigraphy
• C. Colonoscopy
• D. Endoscopic clipping

Answer: (A)

In a hemodynamically unstable patient with a massive lower GI bleed, the priority is rapid control of the hemorrhage. Emergent exploratory laparotomy provides direct visualization of the bleeding source and immediate hemostasis, which is essential when time is critical and ongoing blood loss threatens life. Nonoperative options like nuclear RBC scintigraphy or endoscopic attempts require patient stability, bowel preparation, and time, and are unlikely to localize or control a rapid, large bleed in an unstable patient. Endoscopic clipping likewise relies on a favorable view and patient stability, which are not present here. Therefore, urgent surgical exploration is the most appropriate next step to achieve definitive hemorrhage control, with the possibility of vessel ligation or segmental resection as needed.
