Short-bowel syndrome and intestinal failure

Essential points for quick revision.

!
Escalate

Rigors, fever, hypotension or confusion during or after a parenteral infusion requires emergency sepsis assessment, appropriately timed paired line and peripheral cultures and immediate intestinal-failure or infection-team contact. High stoma output with oliguria, postural symptoms, rising creatinine or severe electrolyte disturbance requires urgent fluid and sodium replacement with specialist review.

Synopsis

Relate remaining bowel anatomy to fluid and nutrient loss, manage a high-output stoma without worsening sodium depletion, recognise line sepsis and intestinal-failure liver disease, and coordinate home parenteral support or teduglutide through a specialist centre.

  • Intestinal failure means gut function is insufficient to absorb macronutrients, water or electrolytes so intravenous supplementation is needed; short bowel is one anatomical cause.
  • Record the length and segment of remaining small bowel, whether colon is in continuity, ileocaecal valve, stoma and fistulae because these predict fluid and nutritional behaviour.
  • A jejunostomy with high output loses sodium-rich fluid; drinking large volumes of plain water or hypotonic drink can increase net sodium and water loss.

Key red flags

High-output stoma dehydration

Output commonly above 1.5 to 2 litres daily with thirst, dizziness, low urine, cramps, weight loss, rising urea or creatinine and hypomagnesaemia suggests net intestinal fluid loss.

Investigation priorities

01
Anatomical reconstructionFirst step

Retrieve operative records and contrast or cross-sectional imaging to document residual jejunum and ileum, colon continuity, valve, stoma, fistula and strictures.

Management branches

OutputHigh-output jejunostomy

Stoma output rises with thirst, falling urine, weight loss or biochemical depletion.

  1. Exclude obstruction, infection, recurrent disease and medicine withdrawal, then measure 24-hour oral intake, output, urine and weight.
  2. Replace intravenous sodium and magnesium when clinically depleted, and use the specialist high-sodium oral rehydration plan while limiting hypotonic fluid.
ChronicReduce parenteral dependence safely

Chronic short-bowel intestinal failure is clinically stable on an optimised regimen.

Key medicines

High-dose loperamideSpecialist doses given 30 to 60 minutes before meals and at night may exceed routine licensed limits in intestinal failure; follow the current BIFA ECG and prescribing guidance.
Proton pump inhibitorA current BNF oral or intravenous regimen selected for early gastric hypersecretion, absorption and ongoing output, then reviewed for continued need.
