Malignant Acute Colonic Obstruction: Multidisciplinary Approach for Endoscopic Management

Area of Science:

• Gastroenterology
• Oncology
• Radiology
• Colorectal Surgery

Background:

• Acute colonic obstruction requires prompt management involving multiple medical specialties.
• Pre-treatment evaluation is crucial for determining appropriate endoscopic stenting indications.
• Contrast-enhanced imaging aids in differentiating benign from malignant strictures and assessing tumor length.

Purpose of the Study:

• To outline a comprehensive approach for evaluating patients with acute colonic malignant obstruction.
• To emphasize the importance of multidisciplinary collaboration in patient management.
• To detail the optimization of endoscopic stenting techniques.

Main Methods:

• Multidisciplinary team evaluation involving radiologists, surgeons, and oncologists.
• Utilizing contrast-enhanced imaging for accurate diagnosis and stricture assessment.
• Reviewing current evidence on endoscopic stenting for palliative and bridge-to-surgery indications.

Main Results:

• Endoscopic stenting is the gold standard for palliative treatment of malignant colonic obstruction.
• Stenting as a bridge to surgery shows short-term surgical benefits but no long-term improvement.
• Careful evaluation is necessary for patients on antiangiogenic agents due to perforation risk.

Conclusions:

• A collaborative, multidisciplinary approach is essential for optimal patient evaluation and management of acute colonic malignant obstruction.
• Accurate pre-treatment assessment and optimized stenting techniques improve patient outcomes.
• Further research with robust data is needed to solidify evidence-based guidelines.
