Management of small bowel fistulas

Area of Science:

• Gastroenterology
• Surgical Gastroenterology
• Abdominal Surgery

Background:

• Small intestine fistulas present significant management challenges.
• High mortality rates and prolonged hospitalizations are common.
• Previous management strategies included immediate resection and anastomosis.

Purpose of the Study:

• To evaluate the outcomes of different management strategies for small intestine fistulas.
• To identify factors influencing spontaneous closure and the success of delayed reconstruction.

Main Methods:

• Retrospective review of 52 patients with small intestine fistulas (1975-1981).
• Analysis of management approaches: early reoperation, delayed reconstruction, and conservative management with total parenteral nutrition.
• Comparison of outcomes including mortality, hospital stay, and fistula closure rates.

Main Results:

• Mortality rate was 38% with an average hospital stay of 95 days.
• 43% of patients (19/44) achieved spontaneous fistula closure.
• Delayed reconstruction with exteriorization (ileostomy and mucous fistula) followed by later anastomosis showed higher success rates than immediate resection.

Conclusions:

• Exteriorization and delayed reconstruction are more successful than immediate resection for complex small intestine fistulas.
• Spontaneous closure is achievable in a significant proportion of patients with total parenteral nutrition.
• Effective management requires a tailored approach considering fistula complexity and patient condition.
