A 40 years old male with CA descending colon presents with acute intestinal obstruction. Emergency treatment of choice is
## **Core Concept**
The question revolves around the management of acute intestinal obstruction due to carcinoma (CA) of the descending colon. Intestinal obstruction is a surgical emergency that requires prompt intervention to prevent complications such as ischemia, perforation, and sepsis. The management strategy depends on the cause, site, and severity of the obstruction.
## **Why the Correct Answer is Right**
The correct approach for a patient with acute intestinal obstruction due to CA of the descending colon involves stabilizing the patient and relieving the obstruction. For left-sided obstructions, like those in the descending colon, **.diverting colostomy or resection with primary anastomosis (if feasible)** are considered. However, in an emergency setting with significant obstruction and possible ischemia, a **.diverting colostomy** might be performed to relieve the obstruction, although **resection with primary anastomosis or Hartmann's procedure** are often preferred for left-sided lesions if the patient's condition allows.
## **Why Each Wrong Option is Incorrect**
- **Option A:** This option is incorrect because, although it might seem like a plausible intervention, it does not accurately represent the standard emergency management for CA of the descending colon with acute obstruction.
- **Option B:** This option is incorrect as it does not align with the standard treatment protocols for acute intestinal obstruction caused by CA of the descending colon.
- **Option D:** This option is incorrect because it does not accurately reflect the immediate treatment of choice for acute intestinal obstruction due to CA of the descending colon.
## **Clinical Pearl / High-Yield Fact**
A key point to remember is that for acute intestinal obstructions, especially those caused by malignancies, the priority is to relieve the obstruction and assess the viability of the bowel. Hartmann's procedure (resection of the bowel segment with closure of the rectal stump and creation of a colostomy) is often considered in emergency situations, particularly for left-sided obstructions or when primary anastomosis is risky.
## **Correct Answer:** .
