At a glance

Changing wound dressings at home after colorectal surgery is something most people manage successfully, even when it feels daunting at first. The key is preparation, a calm approach, and knowing what is normal versus what needs attention.

This guide covers the practical steps of a dressing change, what to have ready, and how to make the process as comfortable as possible. It applies to open wounds from procedures like fistulotomy, abscess drainage, hemorrhoidectomy, and pilonidal surgery — though your surgical team’s specific instructions always take priority.

Before you start

Gather your supplies

Having everything within reach before you begin makes the process smoother:

  • Clean dressings — the type your surgical team recommended
  • Saline solution or clean warm water — for dampening and gentle cleaning
  • Gauze pads or soft cloths — for cleaning around the wound
  • Disposal bag — for the used dressing
  • Pain relief — if you find dressing changes uncomfortable, taking your pain medication 30 to 45 minutes beforehand can help
  • Mirror — some people find a hand mirror helpful for wounds they cannot easily see
  • Clean towel — to sit or lie on

Wash your hands thoroughly

This is the single most important step. Wash with soap and warm water for at least 20 seconds. If you have been given hand sanitiser, use it as well.

Choose your timing

Many people find dressing changes easiest:

  • After a sitz bath or shower — the warm water softens any dried discharge and makes removal gentler
  • After a bowel movement — so the fresh dressing stays clean longer
  • When you are not rushed — giving yourself time reduces anxiety

The dressing change

Removing the old dressing

  1. Wash your hands
  2. Gently peel the dressing away from the skin — if it sticks, dampen it with warm water or saline and wait a minute
  3. Look at the old dressing before disposing of it — noting the amount and colour of any discharge helps you track changes over time
  4. Place the used dressing in your disposal bag

Cleaning the wound

  1. Use saline or clean warm water on a gauze pad
  2. Gently clean around the wound, wiping away from the wound edges rather than into them
  3. Do not scrub — gentle dabbing or wiping is sufficient
  4. Let the area air dry briefly or pat dry very gently with clean gauze

What to look at

While the wound is uncovered, take a moment to check:

  • Colour — healthy healing tissue is pink or red. Dark, grey, or green tissue is worth reporting
  • Discharge — some clear or slightly yellow discharge is normal. Thick, green, or foul-smelling discharge needs attention
  • Swelling — some swelling is expected, but increasing redness or warmth spreading away from the wound is a concern
  • Size — the wound should be gradually getting smaller over weeks

Applying the new dressing

  1. Open the new dressing without touching the part that will contact the wound
  2. Place it gently over the wound
  3. Secure with tape or adhesive as needed — avoid pulling the skin taut
  4. Make sure the dressing is comfortable and will stay in place with movement

Making it more comfortable

Dressing changes can be uncomfortable, especially in the early days. Strategies people find helpful:

  • Take pain relief beforehand — timing it so it peaks during the change
  • Do it after a warm bath — the tissue is softer and more relaxed
  • Breathe slowly — tension makes everything feel worse
  • Have someone help — a partner or family member can assist with hard-to-reach areas
  • Use a non-adherent dressing — if your team has not specified a type, ask about dressings designed not to stick
  • Keep a routine — the process gets easier and faster with practice

Wound packing

Some wounds — particularly after fistulotomy or abscess drainage — need to be packed with ribbon gauze or similar material. Wound packing is usually demonstrated by your surgical team or district nurse before you are expected to do it at home.

If you have been asked to pack the wound yourself:

  • Follow the specific technique you were shown
  • Pack gently — the material should fill the wound loosely, not be forced in tightly
  • The amount of packing material will decrease as the wound gets smaller
  • If you are unsure whether you are doing it correctly, ask for a follow-up demonstration

Tracking your healing

Keeping a simple record of each dressing change can be helpful:

  • Date and time
  • Amount and type of discharge
  • Pain level
  • Anything different from last time

This information is valuable at follow-up appointments and helps you notice gradual improvements that are hard to see day to day.

When to get help

Most wound healing after colorectal surgery is straightforward, but contact your surgical team if you notice:

  • A sudden increase in pain that is not improving
  • Heavy or persistent bleeding
  • Discharge that becomes thick, green, or foul-smelling
  • Increasing redness or warmth spreading from the wound
  • Fever or feeling generally unwell
  • The wound appearing to get larger rather than smaller

These signs do not always mean something is wrong, but they are worth checking.

Common questions

How often should I change the dressing?

This depends on your surgical team's instructions and the type of wound. Many people change dressings once or twice a day, and after bowel movements if the dressing becomes soiled. Follow the specific guidance you were given at discharge — frequency varies depending on the procedure and how the wound is healing.

Is it normal for the dressing to stick to the wound?

Some sticking is common, especially with gauze dressings. Dampening the dressing with warm water or saline before removal can help reduce discomfort. If the dressing is consistently sticking and causing pain or bleeding on removal, mention this to your surgical team — they may suggest a non-adherent dressing type.

What if I see blood on the dressing?

A small amount of blood-tinged fluid on the dressing is normal during healing, especially in the first week or two. What matters is the trend — is the amount decreasing over time? If bleeding is heavy, increasing, or soaking through dressings quickly, contact your surgical team.

Can I shower with the wound uncovered?

Many surgical teams encourage gentle showering as part of wound care. Letting clean water run over the wound is often fine and can help keep the area clean. Avoid directing a strong jet of water at the wound. Pat dry gently afterwards and apply a fresh dressing. Check with your team for specific guidance about your wound.

Do I need sterile supplies at home?

For most open wounds healing after colorectal surgery, a clean technique is sufficient rather than a fully sterile one. Clean hands, clean supplies, and a clean surface to work on are the priorities. Your surgical team will let you know if your specific wound requires sterile dressings or equipment.

See all the signs

For this topic, get medical advice if you notice:

  • Heavy bleeding that soaks through the dressing quickly
  • Increasing redness, warmth, or swelling around the wound
  • Fever or feeling unwell
  • Foul-smelling discharge
  • Pain that is getting significantly worse

Recording how you feel is not the same as being checked. These are the signs that need a doctor’s attention.

Call 911 or go to the emergency room now if you have:

  • bleeding that will not stop, a lot of blood (the toilet water turns red, or you pass large clots), or any bleeding with feeling faint or dizzy
  • fainting, a racing heart or trouble breathing
  • confusion or slurred speech, extreme shivering, no urine in a day, or blotchy skin
  • sudden severe belly pain, or a swollen, hard belly with vomiting or not passing stool or gas
  • you cannot pass urine at all, or your bladder feels full and painful and you can’t empty it
  • redness, swelling or severe pain spreading quickly around your anus, genitals or groin, especially with a fever or feeling very ill
  • a fever with a painful swelling near your anus if you have diabetes or a weakened immune system (for example, from chemotherapy or transplant medicines)
  • black, tarry stools

Call your doctor or go to urgent care today (or the ER if you can’t be seen today) if you have:

  • a temperature of 100.4°F (38°C) or higher, chills, vomiting, or feeling generally unwell
  • pain that is getting worse over days, or severe pain that stops you sitting or sleeping
  • a hot, swollen or very tender lump near your anus or at the top of the crease between your buttocks, or foul-smelling discharge
  • trouble urinating
  • bleeding that is getting heavier or more frequent, or blood mixed into your stool
  • feeling much more tired than usual, looking pale, or getting out of breath more easily than you used to
  • not passing stool for several days, or new belly pain

Make an appointment with your doctor if:

  • you have never had these symptoms checked by a doctor or nurse — whatever your age
  • you have had rectal bleeding for more than 3 weeks
  • your bowel movements have been looser, thinner or more frequent than usual for 3 weeks or more, or you have lost weight without trying
  • symptoms have not settled after a week or so, or keep coming back
  • you notice a new lump near your anus, between your buttocks or in your belly, or an itch or discharge that does not clear
  • you have new leakage or trouble controlling your bowels
  • you are 45 or over, or have a family history of bowel cancer or inflammatory bowel disease, and any of these symptoms are new for you

If you are unsure, it is always reasonable to ask. If things feel overwhelming, call or text 988 (Suicide & Crisis Lifeline) or chat at 988lifeline.org, any time. If you don’t feel safe, call 911.
