Treatment of choice for annular pancreas is:-
**Core Concept**
Annular pancreas is a rare congenital anomaly where pancreatic tissue encircles the second part of the duodenum, potentially causing duodenal obstruction. The treatment of choice aims to relieve the obstruction and ensure adequate pancreatic and duodenal function.
**Why the Correct Answer is Right**
Surgical treatment, specifically duodeno-duodenostomy, is the preferred method for managing annular pancreas. This procedure involves creating a surgical connection between the proximal and distal segments of the duodenum to bypass the obstructed segment, thereby restoring normal intestinal continuity. The goal is to avoid pancreatic resection, which could compromise pancreatic function and lead to exocrine insufficiency.
**Why Each Wrong Option is Incorrect**
**Option A:**
This option is incorrect as it does not address the duodenal obstruction caused by annular pancreas. Duodenal atresia or stenosis may require different treatment approaches.
**Option B:**
This option is incorrect as it is not the preferred surgical treatment for annular pancreas. Pancreatic resection may be considered in cases of pancreatic pathology, but it is not the primary goal in treating annular pancreas.
**Option C:**
This option is incorrect as it does not address the mechanical obstruction caused by annular pancreas. Endoscopic treatments may be useful in certain cases of duodenal obstruction but are not the standard treatment for annular pancreas.
**Clinical Pearl / High-Yield Fact**
In cases of suspected annular pancreas, imaging studies such as CT or MRI scans can help confirm the diagnosis by visualizing the pancreatic tissue encircling the duodenum. This knowledge is crucial for planning the appropriate surgical intervention.
**Correct Answer:** C. Duodeno-duodenostomy.
