Large Bowel Obstruction: Etiologies, Diagnosis, and Management

Area of Science:

• Gastroenterology
• Surgical Oncology
• Abdominal Imaging

Background:

• Large bowel obstructions (LBOs) are a common surgical emergency.
• Prompt diagnosis and management are crucial due to high mortality risks, especially with colonic perforation.
• Current diagnostic approaches involve clinical assessment and computed tomography (CT) scans for stable patients.

Purpose of the Study:

• To provide a comprehensive overview of the etiologies of LBO.
• To outline diagnostic methods for LBO, including the role of CT imaging.
• To discuss general and specific management principles for common LBO causes like colorectal cancer and strictures.

Main Methods:

• Literature review of existing studies on large bowel obstructions.
• Synthesis of information regarding diagnostic techniques and imaging modalities.
• Analysis of management strategies for various etiologies of LBO.

Main Results:

• LBO diagnosis requires a combination of clinical acumen and advanced imaging like CT scans.
• Colorectal cancer and strictures are identified as frequent causes of LBO.
• Timely surgical intervention is often necessary to prevent complications such as perforation.

Conclusions:

• Effective management of LBO hinges on accurate diagnosis and decisive surgical planning.
• Understanding the diverse etiologies of LBO is key to tailoring treatment strategies.
• This review consolidates essential knowledge for clinicians managing patients with large bowel obstructions.
