Adhesive Small Bowel Obstruction: Predictive Radiology to Improve Patient Management

Area of Science:

• Radiology
• Gastroenterology
• Emergency Medicine

Background:

• Adhesive small bowel obstruction (SBO) is a frequent cause of emergency visits with significant morbidity and mortality.
• Management has shifted towards nonoperative treatment, necessitating rapid identification of strangulation requiring surgery.

Purpose of the Study:

• To review the role of CT imaging in predicting the management needs for adhesive SBO.
• To update on CT signs for ischemia, bowel resection, obstruction types, and nonoperative management outcomes.

Main Methods:

• Review of current literature on CT imaging in adhesive SBO.
• Analysis of CT features associated with ischemia, strangulation, and obstruction patterns.
• Evaluation of CT predictors for successful nonoperative management.

Main Results:

• CT is the primary imaging modality for diagnosing SBO, locating the obstruction, and identifying complications.
• Specific CT signs can predict the need for bowel resection due to ischemia.
• CT features help differentiate between open-loop and closed-loop obstructions and types of adhesions, influencing management decisions.

Conclusions:

• CT imaging plays a pivotal role in guiding the management of adhesive SBO.
• Accurate interpretation of CT findings aids in predicting strangulation, guiding surgical vs. nonoperative treatment, and optimizing patient outcomes.
