## Core Concept
The question pertains to the complications associated with gallstones. Gallstones can lead to various complications, including obstructive jaundice, cholangitis, pancreatitis, and cholecystitis, among others. Understanding these complications is crucial for managing patients with gallstone disease.

## Why the Correct Answer is Right
Option describes a condition that is not typically listed as a direct complication of gallstones. Common complications include:
- **Cholecystitis**: Inflammation of the gallbladder, often due to obstruction of the cystic duct by a stone.
- **Obstructive jaundice**: Jaundice caused by obstruction of the bile ducts, which can occur if a stone moves into the common bile duct (choledocholithiasis).
- **Pancreatitis**: Inflammation of the pancreas, which can be triggered by a stone obstructing the ampulla of Vater, where the pancreatic and bile ducts empty into the small intestine.
- **Cholangitis**: Infection of the bile ducts, often ascending from the intestine, which can occur if there is obstruction of the bile ducts by stones.

## Why Each Wrong Option is Incorrect
- **Option A:** This option is a known complication of gallstones, as stones can obstruct the bile ducts leading to jaundice.
- **Option B:** Also a complication, as obstruction by stones can lead to infection and inflammation of the bile ducts.
- **Option C:** Similarly, pancreatitis is a recognized complication when stones obstruct the pancreatic duct or ampulla of Vater.

## Clinical Pearl / High-Yield Fact
A key point to remember is that while **choledocholithiasis** (stones in the common bile duct) can lead to obstructive jaundice, cholangitis, and pancreatitis, not all listed options are direct and common complications of gallstones.

## Correct Answer Line
**Correct Answer: D.**
