Pneumatosis Intestinalis in Adults

Area of Science:

• Gastroenterology
• Surgical Pathology
• Diagnostic Imaging

Background:

• Pneumatosis on imaging frequently prompts surgical consultation.
• The presence of gas within the bowel wall can stem from benign or pathologic causes.
• Pathologic pneumatosis is often linked to bowel ischemia or necrosis.

Purpose of the Study:

• To develop a grading scale for identifying pneumatosis associated with pathologic etiologies.
• To provide management recommendations for different types of pneumatosis.
• To aid clinicians in differentiating benign from critical pneumatosis.

Main Methods:

• Development of a novel grading scale for pneumatosis.
• Integration of clinical findings, laboratory results, and imaging data.
• Correlation of grading scale with patient outcomes and need for surgical intervention.

Main Results:

• The grading scale assists in identifying pneumatosis requiring surgical exploration.
• Specific clinical and imaging findings predict pathologic pneumatosis.
• Key indicators for abdominal exploration include elevated lactate, sepsis, hypotension, portal venous gas, and peritonitis.

Conclusions:

• A structured approach, including a grading scale, improves the diagnosis of pathologic pneumatosis.
• Clinical and imaging signs are crucial for guiding management decisions.
• Prompt surgical exploration is indicated in cases of suspected bowel ischemia or necrosis.
