Massive colonic haemorrhage--the case for right hemicolectomy

Area of Science:

• Gastroenterology
• Surgical Oncology
• Colorectal Surgery

Background:

• Massive colonic hemorrhage presents a significant surgical challenge.
• Determining the optimal surgical strategy for obscure or suspected colonic bleeding is critical for patient outcomes.

Purpose of the Study:

• To evaluate the efficacy of different surgical approaches for massive colonic hemorrhage.
• To provide evidence-based recommendations for surgical management based on bleeding site localization.

Main Methods:

• Retrospective analysis of 14 patients undergoing surgery for massive colonic hemorrhage.
• Review of existing literature on surgical interventions for colonic bleeding.
• Comparison of outcomes based on surgical procedure: right hemicolectomy, left-sided resection, and subtotal colectomy.

Main Results:

• Right hemicolectomy yielded good outcomes, even with equivocal indications of a right-sided source.
• Left-sided resection for unproven left-sided bleeding resulted in high mortality and rebleeding.
• Subtotal colectomy had a significant mortality rate (2 out of 5 patients died).

Conclusions:

• Right hemicolectomy is the preferred approach for massive colonic hemorrhage when the bleeding source is not definitively identified but suspected to be right-sided.
• Left-sided resection should be reserved for cases with confirmed left-sided bleeding to avoid high mortality.
• Subtotal colectomy is indicated for cases with no localization clues, equivocal left-sided source, or bilateral disease.
