Pseudo-pseudo-obstruction: lessons in diagnosis and management

Area of Science:

• Gastroenterology
• Internal Medicine

Background:

• Chronic intestinal pseudo-obstruction (CIP) is a rare, disabling disorder characterized by symptoms and radiological signs of bowel obstruction.
• Current diagnostic criteria may exclude patients with severe gastrointestinal symptoms but without radiological evidence of obstruction.

Discussion:

• The diagnosis of CIP should be expanded to include patients with severe GI symptoms, manometric evidence of CIP, or demonstrable end-organ pathology.
• A case of pseudo-pseudo-obstruction is presented, highlighting diagnostic challenges and the importance of small intestine manometry.
• Mechanical obstruction can mimic CIP, and CIP can present with mechanical obstruction, necessitating careful evaluation.

Key Insights:

• Small intestine manometry is crucial for diagnosing CIP, especially in complex cases.
• Prokinetic therapy trials can aid in differentiating CIP from mechanical obstruction.
• Expanding diagnostic criteria improves recognition of CIP in patients with severe GI distress.

Outlook:

• Further research into the pathophysiology and diagnostic markers of CIP is warranted.
• Standardized diagnostic protocols incorporating manometry and clinical features will enhance patient care.
• Improved understanding and diagnosis of CIP will lead to more effective management strategies.
