**Core Concept:** Chronic calculous cholecystitis is a condition characterized by the presence of gallstones in the gallbladder, which can lead to inflammation (chronic cholecystitis) and pain in the right upper quadrant. The clinical presentation, liver function tests, and ultrasound findings help differentiate between various causes of RUQ pain.

**Why the Correct Answer is Right:** In this case, the patient has a history of jaundice in the past, indicating a potential biliary tract involvement. Although the liver function tests are normal, the ultrasound examination shows chronic calculous cholecystitis, which suggests the gallbladder as the primary site of pathology. Furthermore, the common bile ducts are not dilated, ruling out choledocholithiasis as a cause for the pain. Therefore, the procedure of choice to address the patient's RUQ pain would be cholecystectomy (gallbladder removal), specifically laparoscopic cholecystectomy (keyhole surgery), as it addresses the primary site of pathology and provides symptomatic relief.

**Why Each Wrong Option is Incorrect:**

A. Choledocholithiasis (option A) is incorrect because the common bile ducts are not dilated on ultrasound examination.
B. Hepatitis (option B) is incorrect as liver function tests are within normal limits, ruling out liver disease as the cause of pain.
C. Cirrhosis (option C) is incorrect since liver function tests are normal, and the patient has a history of jaundice in the past, but the liver is not involved in this case.
D. Pancreatic pathology (option D) is incorrect as there are no signs of pancreatitis or involvement of the pancreas on ultrasound examination.

**Clinical Pearl:** In cases of RUQ pain, considering the patient's history and examination findings, it is essential to differentiate between various causes like choledocholithiasis, hepatitis, cirrhosis, and pancreatic pathology. A thorough clinical evaluation and imaging studies can guide the appropriate management, such as cholecystectomy for gallbladder-related pain and other interventions for other causes like ERCP for choledocholithiasis.
