Idiopathic encapsulating peritoneal sclerosis presenting with abdominal mass.

Area of Science:

• Gastroenterology
• Abdominal Surgery

Background:

• Encapsulating peritoneal sclerosis (EPS) is a rare condition characterized by a fibrous membrane encasing the abdominal organs.
• Idiopathic EPS typically presents as intestinal obstruction, often mimicking other abdominal pathologies.

Purpose of the Study:

• To report a case of primary encapsulating peritoneal sclerosis presenting with intermittent abdominal mass and pain.
• To highlight the diagnostic utility of contrast-enhanced CT (CECT) and the role of surgical intervention.

Main Methods:

• A case presentation of a male patient with recurrent abdominal symptoms.
• Diagnostic imaging using contrast-enhanced CT (CECT) to identify a thickened peritoneal membrane.
• Surgical intervention via midline laparotomy with adhesiolysis and membrane incision.

Main Results:

• CECT revealed a thick membrane encasing clumped small bowel loops, consistent with an abdominal cocoon.
• Histopathological examination confirmed primary encapsulating peritoneal sclerosis.
• Surgical treatment led to resolution of symptoms.

Conclusions:

• Primary encapsulating peritoneal sclerosis is a rare cause of intestinal obstruction, often diagnosed via CECT.
• Surgical intervention is the preferred treatment for idiopathic cases of abdominal cocoon.
• Early diagnosis and surgical management are crucial for favorable outcomes.
