# 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.

Updated Nov 13, 2026

## Key points

- Hypoactive bowel sounds are expected early after abdominal surgery; opioids and the operation itself can cause ileus.
- Ask every day about flatus and the last bowel movement.
- Leak warning signs: fast pulse, a patient getting worse, abdominal pain beyond the wound, and discharge from the drain or rectum; purulent drain content weighs most.
- A suspected leak is investigated with blood tests (CRP with white cells) and a CT scan: call early.
- Walk early and build up slowly; press a pillow over the wound when coughing or sneezing.
- Wound: edges pulling apart, drainage, bleeding, redness, warmth or worse pain must be reported.

## 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.
