CT after uncomplicated esophageal sclerotherapy

Area of Science:

• Radiology
• Gastroenterology
• Medical Imaging

Background:

• Endoscopic esophageal variceal sclerotherapy is a common procedure for managing gastroesophageal varices.
• Post-procedure imaging interpretation can be challenging due to expected inflammatory and fluid changes.

Purpose of the Study:

• To describe the computed tomography (CT) findings following uncomplicated endoscopic esophageal variceal sclerotherapy.
• To help differentiate normal post-procedural changes from complications on CT scans.

Main Methods:

• Prospective CT scans of the lower chest were obtained before and after sclerotherapy in nine patients.
• Key CT findings were systematically documented and analyzed.

Main Results:

• Common CT findings included esophageal wall thickening, low attenuation within the esophageal wall (laminated appearance), mediastinal effusion, obliterated mediastinal fat planes, thickened diaphragmatic crura, pleural effusions, and subsegmental atelectasis.
• Changes were less pronounced in patients with prior sclerotherapy or lower sclerosant volume.
• No mediastinal or pleural gas was observed.

Conclusions:

• CT imaging demonstrates predictable changes after uncomplicated esophageal variceal sclerotherapy.
• Familiarity with these CT alterations is essential for accurate interpretation and avoiding misdiagnosis of complications.
