Overview
An intestinal fistula to the abdominal wall represents an abnormal connection between the bowel and the abdominal fascia, often requiring intervention to manage infection, prevent complications, and achieve closure 1.Diagnosis
Imaging studies (CT, MRI) essential for defining fistula tract and extent 1.
Contrast studies (e.g., fistulography) may delineate the pathway and connections 1.
Clinical assessment for signs of peritonitis, sepsis, and nutritional status 1.Management
First-line treatments: Surgical intervention (primary repair or diversion) is often necessary 1.
Adjunctive therapies: Fibrin sealant (e.g., Tisseel) applied via catheter can effectively seal tracts in selected cases, showing promise in closure rates 1.
Antibiotics: Broad-spectrum coverage initiated empirically, tailored based on culture results 1.
Nutritional support: Essential for patients with malnutrition or prolonged disease 1.Special Populations
Pregnancy: Limited data; management focuses on stabilizing maternal condition and fetal well-being, often requiring multidisciplinary care 1.
Pediatrics: Early surgical intervention and meticulous wound care crucial due to rapid growth and healing dynamics 1.
Elderly: Consider comorbidities and functional status; conservative management may be considered if surgical risks are high 1.
Comorbidities: Presence of underlying conditions like malignancy or inflammatory bowel disease influences treatment complexity and outcomes 1.Key Recommendations
Surgical intervention is recommended as the primary approach for managing intestinal fistulas to the abdominal wall 1 (Evidence: Strong).
Use of fibrin sealant (e.g., Tisseel) can be considered as an adjunctive therapy to seal fistula tracts effectively 1 (Evidence: Moderate).
Tailored antibiotic therapy based on clinical suspicion and culture results is crucial to manage infection 1 (Evidence: Moderate).References
