**Core Concept**
Distal gastric carcinoma refers to a type of cancer located in the lower part of the stomach. The management of this condition often involves surgical procedures to remove the tumor and affected tissue.

**Why the Correct Answer is Right**
The procedure commonly performed for distal gastric carcinoma is a gastrectomy with lymphadenectomy. This involves the surgical removal of the stomach (gastrectomy) and the surrounding lymph nodes (lymphadenectomy) to ensure the complete removal of cancerous tissue. The procedure can be performed either through an open incision or laparoscopically, depending on the surgeon's preference and the patient's overall condition.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because it does not specify a procedure that is commonly performed for distal gastric carcinoma. While a gastrojejunostomy may be performed as a palliative procedure to bypass the obstruction caused by the tumor, it is not the primary treatment for distal gastric carcinoma.
* **Option B:** This option is incorrect because a Whipple procedure is typically performed for pancreatic cancer, not distal gastric carcinoma.
* **Option C:** This option is incorrect because a Heller myotomy is a procedure performed to treat achalasia, not distal gastric carcinoma.

**Clinical Pearl / High-Yield Fact**
It is essential to note that the choice of surgical procedure for distal gastric carcinoma depends on the location and extent of the tumor, as well as the patient's overall health and preferences.

**Correct Answer:** D.
