Treatment options in obstructed left-sided colonic cancer

Area of Science:

• Gastroenterology
• Surgical Oncology
• Oncology

Background:

• Colorectal cancer (CRC) frequently presents as a surgical emergency, with large bowel obstruction occurring in up to 29% of cases.
• Patients with obstructive CRC are often elderly and have significant co-morbidities, complicating treatment decisions.
• Traditional management involved staged surgical procedures, but current trends favor primary resection and anastomosis.

Purpose of the Study:

• To compare the efficacy of primary resection and anastomosis versus self-expanding metallic stents (SEMS) for managing obstructive colorectal cancer in elderly patients.
• To evaluate treatment outcomes, including long-term survival and optimal approach, for this patient demographic.

Main Methods:

• Review of treatment modalities for colorectal cancer presenting with large bowel obstruction.
• Analysis of outcomes associated with staged surgical procedures, primary resection and anastomosis, and SEMS (as a bridge to surgery or definitive palliation).

Main Results:

• No significant difference in long-term survival was observed between primary resection and anastomosis and SEMS treatment.
• SEMS can effectively alleviate obstruction and serve as a bridge to surgery or as a palliative measure.

Conclusions:

• Both primary resection and anastomosis and SEMS are viable options for managing obstructive colorectal cancer in elderly patients.
• There is currently no definitive consensus on the optimal treatment strategy for this patient group, highlighting the need for further research and individualized treatment planning.
