Endoscopic stenting in colorectal cancer

Area of Science:

• Gastroenterology
• Surgical Oncology

Background:

• Acute malignant large bowel obstruction is a critical emergency in colorectal cancer (CRC).
• Management options include upfront surgery or self-expanding metallic stents (SEMS) as a bridge to elective surgery.
• SEMS may facilitate earlier chemotherapy initiation in metastatic CRC patients.

Purpose of the Study:

• To review the presentation of acute malignant large bowel obstruction.
• To introduce the procedural steps for SEMS insertion.
• To evaluate the safety, short-term, and long-term outcomes of SEMS in both curative and palliative settings for malignant large bowel obstruction.

Main Methods:

• Literature review of SEMS for malignant large bowel obstruction.
• Description of SEMS insertion techniques.
• Analysis of safety profiles and patient outcomes (short- and long-term).

Main Results:

• SEMS present a viable alternative to upfront surgery for malignant large bowel obstruction.
• SEMS can facilitate earlier chemotherapy in metastatic patients.
• Conflicting data exist regarding long-term outcomes and complications associated with SEMS.

Conclusions:

• SEMS show promise in managing acute malignant large bowel obstruction but have associated complications.
• Further research and debate are needed to establish definitive indications for SEMS.
• The safety and efficacy of SEMS require continued evaluation in both curative and palliative contexts.
