Surgery for obscure lower gastrointestinal bleeding in India

Area of Science:

• Gastroenterology
• Surgical Oncology
• Hepatology

Background:

• Obscure lower gastrointestinal hemorrhage (OLGIH) presents differently in India compared to Western countries, with younger patients, varied causes, and limited resources.
• Traditional localizing investigations are often infrequently performed in the Indian healthcare setting.

Purpose of the Study:

• To evaluate the outcome of a management strategy for obscure lower gastrointestinal hemorrhage (OLGIH) in India.
• To assess the efficacy of early surgical exploration and targeted resection or right hemicolectomy for OLGIH.

Main Methods:

• A retrospective review of 62 patients with OLGIH managed between 1996 and 2003.
• Fifty patients underwent surgery (emergency or elective), with lesion localization and resection or blind right hemicolectomy if the source was unidentified.

Main Results:

• The bleeding source was identified and resected in 66% of surgical patients (jejunal or ileocecal lesions).
• Seventeen patients (34%) had no lesion found and underwent right hemicolectomy.
• The 30-day mortality rate was 12%, with causes including persistent bleeding and organ failure. Rebleeding occurred in 10% of patients over a mean follow-up of 31 months.

Conclusions:

• Early surgical intervention is recommended for patients with obscure lower gastrointestinal hemorrhage (OLGIH) in India.
• Right hemicolectomy is a viable option when the bleeding source is not identified during surgery.
• Cirrhosis was a significant predictor of rebleeding in the right hemicolectomy group, suggesting a need for careful monitoring.
