Summary about Disease
A gastrocutaneous fistula is an abnormal connection between the stomach and the skin, allowing gastric contents to leak through the skin surface. It can be a debilitating condition leading to malnutrition, infection, and skin breakdown.
Symptoms
Drainage of gastric contents (stomach acid, food) through an opening in the skin
Skin irritation, redness, and pain around the fistula site
Abdominal pain
Fever (if infection is present)
Malnutrition, weight loss, and dehydration
Electrolyte imbalances
Causes
Surgical complications: Most commonly occurs after abdominal surgery, such as gastrectomy, gastric bypass, or other procedures involving the stomach.
Trauma: Penetrating abdominal injuries.
Inflammatory bowel disease (IBD): Crohn's disease can cause fistulas.
Cancer: Tumors in the stomach or nearby organs.
Infection: Abscesses or other infections in the abdominal cavity.
Radiation therapy: Damage to tissues from radiation.
Foreign bodies: Rarely, ingested foreign bodies can erode through the stomach wall.
Medicine Used
H2 receptor antagonists or Proton Pump Inhibitors (PPIs): To reduce gastric acid secretion (e.g., ranitidine, omeprazole).
Octreotide: A somatostatin analog that inhibits gastric secretion and intestinal motility.
Antibiotics: To treat infection.
Pain medication: For pain management.
Total Parenteral Nutrition (TPN): Intravenous nutrition to bypass the gastrointestinal tract.
Is Communicable
No, a gastrocutaneous fistula is not communicable. It is not caused by an infectious agent and cannot be transmitted from person to person.
Precautions
Meticulous wound care: Keeping the skin around the fistula site clean and dry.
Protective dressings: Using dressings to absorb drainage and protect the skin.
Nutritional support: Maintaining adequate nutrition, often through TPN or enteral feeding.
Fluid and electrolyte management: Addressing any imbalances.
Preventing infection: Antibiotics as needed and vigilant monitoring for signs of infection.
How long does an outbreak last?
There is no "outbreak" of a gastrocutaneous fistula. The duration of the condition depends on the underlying cause and the success of treatment. Some fistulas may close spontaneously with conservative management, while others require surgical intervention for closure. Healing time varies from weeks to months.
How is it diagnosed?
Physical examination: Observing drainage from an opening in the abdominal wall.
Contrast studies: A contrast agent (e.g., Gastrografin) is swallowed or injected, and X-rays or CT scans are taken to visualize the fistula tract.
Endoscopy: To visualize the stomach and identify the origin of the fistula.
Fistulogram: Injecting contrast directly into the fistula tract and taking X-rays.
Laboratory tests: To assess nutritional status, electrolyte balance, and infection (e.g., complete blood count, electrolytes, albumin).
Timeline of Symptoms
The timeline of symptoms can vary, but typically:
Post-operative/Trauma: Drainage begins days to weeks after surgery or injury.
Early symptoms: Skin irritation, drainage of gastric contents.
Progressive symptoms: Abdominal pain, malnutrition, dehydration, electrolyte imbalances, and potential infection may develop over days to weeks if untreated.
Important Considerations
Gastrocutaneous fistulas are complex conditions requiring a multidisciplinary approach, including surgeons, gastroenterologists, dietitians, and wound care specialists.
Early diagnosis and treatment are crucial to prevent complications.
Nutritional support is essential to promote healing.
Surgical closure may be necessary for persistent fistulas.
Patient education and support are important for managing the condition and preventing complications.
