Adhesive small bowel obstruction - an update.

Area of Science:

• Gastroenterology
• Abdominal Surgery
• Surgical Pathology

Background:

• Small bowel obstruction (SBO) represents a significant portion of emergency surgical admissions and procedures.
• Intra-abdominal adhesions are the leading cause of SBO, persisting even with laparoscopic surgery.
• Distinguishing adhesive SBO from other etiologies is crucial for appropriate patient management.

Purpose of the Study:

• To review the diagnostic and management strategies for small bowel obstruction, with a focus on adhesive SBO.
• To highlight the importance of clinical presentation and imaging in identifying SBO and its cause.
• To discuss current recommendations for surgical and non-operative treatment of SBO.

Main Methods:

• Review of clinical guidelines and literature pertaining to small bowel obstruction.
• Emphasis on diagnostic criteria including history, physical examination, and computed tomography (CT).
• Discussion of management pathways based on obstruction etiology and presence of complications.

Main Results:

• Adhesive SBO (ASBO) accounts for 65% of SBO cases, often in patients with prior abdominopelvic surgery.
• Non-operative management is successful in 70-90% of ASBO patients.
• CT scans offer higher diagnostic accuracy than plain films for SBO evaluation.
• Urgent surgical intervention is necessary for signs of bowel compromise, ischemia, or peritonitis.

Conclusions:

• Early recognition of SBO, particularly ASBO, is vital for effective treatment.
• Clinical assessment combined with advanced imaging like CT guides management decisions.
• Laparoscopic adhesiolysis and mechanical adhesion barriers are recommended for managing and preventing ASBO.
