Following fistulous conditions give rise to maximum fluid and electrolyte imbalance -
• Enterocutaneous fistulas are classified according to their location and volume of daily output.
• These factors dictate both treatment and morbidity and mortality rates.
• In general, the more proximal the fistula in the ‘intestine’ (but not the stomach), the more serious the problem, with greater fluid and electrolyte loss.
• Maximum fluid and electrolyte imbalance occur in duodenal fistulas
Distal ileal
Gastric
Duodenal
