At a glance

The time between deciding to have fissure surgery and the actual procedure is filled with a particular kind of anxiety. You have been in pain, you have made a big decision, and now you are waiting. Using that waiting period to prepare practically can reduce both the anxiety and the difficulty of recovery.

This guide covers what people commonly wish they had done in the weeks leading up to fissure surgery — whether that is LIS, fissurectomy, or another procedure.

Two to three weeks before

Get your questions answered

If you have not already, write down every question you have about the procedure and contact your surgical team. Common questions at this stage:

  • What exactly will be done during the surgery?
  • What type of anaesthesia will be used?
  • How long will the procedure take?
  • Will I go home the same day?
  • What pain management will be available after?
  • When is my first follow-up appointment?

Having clear answers reduces the uncertainty that drives pre-surgical anxiety.

Start optimising your stool management

This is the single most impactful thing you can do before surgery. People consistently describe the first post-operative bowel movement as one of the most anxiety-inducing parts of the experience. Having soft stools already established makes it significantly easier.

  • Increase fibre gradually — aim for 25 to 30 grams per day
  • Start or continue stool softeners — discuss this with your surgical team
  • Increase water intake to two to three litres per day
  • Reduce foods that constipate — processed foods, excessive dairy, white bread

Arrange time off work

Talk to your employer about the recovery timeline your surgeon has given you. Build in a buffer — many people describe needing a few more days than they initially expected.

One week before

Stock up on supplies

Have everything you need at home before the surgery. You will not want to go shopping in the first few days of recovery.

Essential supplies:

  • Sitz bath basin (or a clean, shallow container that fits over the toilet)
  • Stool softeners and fibre supplements
  • Prescribed pain medication (collect the prescription in advance if possible)
  • Gauze pads for wound care
  • A peri bottle for gentle cleaning
  • Loose, comfortable clothing — nothing tight around the waist or hips
  • Cushion or pillow for sitting

Food supplies:

  • Easy-to-prepare, high-fibre meals — soups, stews, porridge ingredients
  • Soft fruits — bananas, pears, stewed prunes
  • Plenty of water and herbal teas
  • Gentle snacks that require no preparation

Arrange support

Even if you are independent, having someone available for the first day or two is valuable. People describe needing help with:

  • Getting home from the hospital
  • Preparing meals
  • General household tasks
  • Emotional support — the first day can be harder emotionally than expected

Prepare your recovery space

  • Sitz bath set up and ready — you will want to use it within hours of getting home
  • Medication organised — pain relief, stool softeners, any prescribed topical treatments
  • Comfortable seating area — with cushions and entertainment within reach
  • Bathroom stocked — gauze, wipes or peri bottle, clean towels

The day before

Practical preparation

  • Follow any fasting instructions from your surgical team
  • Lay out loose, comfortable clothing for the hospital
  • Charge your phone — you may want it for entertainment and communication
  • Have your hospital bag ready if staying overnight
  • Take a sitz bath to relax the area

Mental preparation

Pre-surgical anxiety is normal. People describe the night before as one of the hardest parts of the entire process. Strategies that people find helpful:

  • Reminding yourself why you made this decision — months of pain, exhausted conservative options
  • Accepting that anxiety is a normal response to surgery
  • Avoiding reading worst-case-scenario accounts online (if you can manage it)
  • Having someone to talk to — a partner, friend, or family member
  • Getting as much sleep as possible, even if it is not perfect

The morning of

  • Follow your fasting instructions
  • Take any medications your team has told you to take
  • Wear loose, comfortable clothing
  • Bring your questions list if you have last-minute queries for the surgeon
  • Remember: the procedure itself is usually the easiest part. It is quick, you are sedated, and it is over before you fully register it.

The single most important preparation

If there is one thing that people wish they had prioritised above all else, it is stool management. Getting your stools soft and established before surgery makes the first few days of recovery dramatically easier. Everything else — supplies, time off, support — matters. But soft stools matter most.

Common questions

How far in advance should I start preparing?

Most people describe two to three weeks before surgery as the ideal time to begin preparation. This gives you time to stock up on supplies, optimise your diet and stool management, and arrange practical support without feeling rushed.

What should I buy before surgery?

A sitz bath basin, stool softeners, fibre supplements, gauze pads, loose comfortable clothing, a cushion for sitting, gentle wipes or a peri bottle, and easy-to-prepare soft foods. Having everything ready before the surgery reduces stress during recovery.

Should I start stool softeners before surgery?

Many people and surgeons recommend starting stool softeners and increasing fibre intake several days before surgery. The first post-operative bowel movement is much easier if your stools are already soft going in.

How much time off work will I need?

This depends on the procedure and your type of work. For LIS surgery, people commonly describe one to two weeks. For fissurectomy, one to three weeks. Desk jobs may allow an earlier return than physically demanding work. Discuss this specifically with your surgeon.

See all the signs

For this topic, get medical advice if you notice:

  • Symptoms that are getting rapidly worse while waiting
  • New bleeding, fever, or signs of infection
  • Severe pain that is not manageable

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.
