Correct Answer » D Explanation |
 |
- Lesser curvature anterior seromyotomy is a surgical technique used during Highly Selective Vagotomy (HSV), also known as Parietal Cell Vagotomy or Proximal Gastric Vagotomy.
- It facilitates identification and division of the terminal branches of the anterior vagal nerve (crow’s foot) supplying the acid-secreting proximal stomach while preserving the antral innervation.
- The procedure is performed for the surgical management of chronic or intractable duodenal ulcer.
- Your uploaded notes specifically state:
- “Lesser Curvature anterior Seromyotomy done for Duodenal Ulcer.”
- The notes also mention that the procedure of choice for chronic duodenal ulcer is Highly Selective Vagotomy.
Why the Other Options Are Incorrect
A. Gastric ulcer
- Gastric ulcers are generally treated by partial gastrectomy, with the procedure depending on the Johnson type of ulcer.
- Lesser curvature anterior seromyotomy is not performed for gastric ulcers.
B. Gastric carcinoma
- Gastric carcinoma requires oncologic gastric resection with lymphadenectomy.
- Seromyotomy has no role in its management.
C. Duodenal blowout
- Duodenal blowout is a postoperative complication, usually after Billroth II gastrectomy.
- Management involves repair of the leak and control of sepsis, not lesser curvature anterior seromyotomy.
