Care after abdominal surgery (appendix, gallbladder, bowel, hernia): drains, return of bowel function and leak warning signs
- Safe practice
After abdominal surgery: watch the pulse, the abdomen and the drains, help bowel function return, get the patient walking, and teach leak and wound signs.
What it is
After surgery on the appendix, gallbladder, bowel or a hernia, the general postoperative care applies (see the perioperative pages). This page adds what is specific to the abdomen: the return of bowel function, drains and what their content means, the warning signs of an anastomotic leak after bowel surgery, wound checks, walking and the teaching for going home.
What it requires
- Vital signs and pain at the frequency of the protocol.
- An abdominal assessment every shift, compared with the last one.
- A drain record: amount and appearance.
- Wound checks and signs of venous thrombosis (leg swelling, calf pain).
- Teaching before discharge.
How it is applied (and why)
- Take vital signs and pain scores as the protocol says, and do not ignore a rising pulse — it is an early leak sign.
- Assess the abdomen each shift: distension, sounds, tenderness — and compare with the last check.
- Ask about flatus, stool and nausea and record them — it shows the bowel waking up or an ileus.
- Check each drain: secured, draining, amount and appearance — purulent or faecal content suggests a leak.
- Help the patient walk early and increase slowly — it helps recovery.
- Teach the patient to press a pillow over the wound when coughing or sneezing — it eases pain.
- Inspect the wound and care for it as the protocol says — infection and opening are caught early.
- Advance the diet as ordered: small meals, new foods slowly, protein every day — it helps healing.
- Teach bowel care: stool softeners or laxatives only with the surgeon's agreement — hard stools are common on opioids.
- Before discharge, teach the warning signs and who to call — complications can appear at home.
In nursing practice
- Ileus after surgery: distension, nausea or vomiting, no gas or stool (see the bowel obstruction page).
- Anastomotic leak after bowel surgery: fast pulse, clinical deterioration, abdominal pain and drain or rectal discharge.
- Surgical site infection: redness, warmth, drainage and pain at the wound.
- Venous thrombosis and embolism: leg swelling or calf pain, breathlessness or chest pain.
- Ostomy care, if one was created, is on its own page.
Common mistakes
- Putting a fast pulse down to pain without assessing the abdomen and the drains.
- Recording the drain volume but not its appearance.
- Keeping the patient in bed to protect the wound.
- Sending the patient home without teaching the warning signs.
Test yourself
Think of the answer, then tap the question to see it.
Which signs raise suspicion of an anastomotic leak?
A fast pulse, a patient getting worse, abdominal pain other than wound pain, and discharge from the drain or rectum, especially purulent content.
Are hypoactive bowel sounds abnormal on the first days after abdominal surgery?
They are expected early after abdominal surgery; the trend, flatus, stool, distension and nausea matter more.
When should the patient call after going home?
Fever, a swollen belly, frequent vomiting, no stool for days or stools that stop, blood in the stool, worsening pain, breathlessness, chest pain, calf pain or wound changes.
Why does early walking matter after abdominal surgery?
It helps recovery; walking more also helps when stools are hard on pain medicines.
