Right upper quadrant abdominal pain

Area of Science:

• Gastroenterology
• Abdominal Pain Diagnosis

Background:

• Right upper quadrant (RUQ) abdominal pain is a common clinical presentation.
• Numerous organ systems can refer pain to the RUQ, including the gallbladder, liver, lungs, pancreas, esophagus, stomach, and thoracic muscles.

Purpose of the Study:

• To provide a clear and comprehensive differential diagnosis for right upper quadrant abdominal pain.
• To highlight the diagnostic challenges, especially when initial investigations like ultrasonography for gallstones are inconclusive.

Main Methods:

• Review of clinical presentations of right upper quadrant abdominal pain.
• Discussion of differential diagnoses based on anatomical and physiological considerations.
• Emphasis on the diagnostic process when gallstones are suspected but not confirmed.

Main Results:

• Right upper quadrant pain can originate from a wide array of conditions beyond the gallbladder.
• Ultrasonography, while useful for gallstones, does not exclude all gallbladder-related causes or other differential diagnoses.
• A systematic approach is crucial for accurate diagnosis.

Conclusions:

• The differential diagnosis of right upper quadrant abdominal pain is broad and complex.
• Clinical evaluation must consider referred pain from multiple organ systems.
• Accurate diagnosis requires careful consideration of all possibilities, even paradoxical presentations like gallstones after negative imaging.
