Pre-surgery Preparation

Please inform your care team if you:

• Take blood-thinning medication(e.g., aspirin, warfarin)
• Use diabetes or blood pressure medication
• Have allergies, especially to anaesthesia or antibiotics)
• Are pregnant, breastfeeding, or have a chronic medical condition

Your doctor may advise adjusting or temporarily stopping certain medications before surgery.

Some colorectal procedures require a clean bowel beforehand. 

This may involve:

• Laxatives or oral bowel cleansing solutions
• A low-fibre or liquid-only diet 1–2 days before surgery
• Clear fluids only (e.g., water, broth, tea) the day before

Always follow your surgeon’s instructions carefully, as preparation varies depending on the procedure.
 

You’ll likely need to stop eating and drinking at least 12 hours before your surgery.

This reduces risks during anaesthesia. Your care team will confirm the exact timing.

Avoid:

• Food
• Milk, juice, or coffee with creamer

You may be allowed small sips of water for essential medication — please check with your nurse.
 

• Shower the night before or morning of surgery
• Use antibacterial soap if instructed.
• Avoid lotions, powders, makeup, or deodorants
• Bring loose clothing and personal items for your stay
• For anal conditions, consider bringing sanitary pads if advised
   

• Arrange for someone to drive you home after the procedure
• Clear your schedule to allow time for rest and healing
• Prepare recovery essentials such as soft foods, wet wipes, cushions and stool softeners.

• Appointment letter or medical reports
• A list of current medications
• NRIC / ID / insurance details
• Comfort items: socks, headphones, reading materials

It is common to experience:

• Mild pain or discomfort (managed with medication)
• Temporary swelling or bleeding around the surgical area
• Changes in bowel habits
• Your surgeon will advise you on wound care, pain management, diet, and when to resume activities.

Seek medical attention if you notice:

• Heavy or sudden bleeding
• Fever or signs of infection
• Severe or worsening pain
• Difficulty passing urine or stool
• Symptoms of a blood clot (leg swelling chest pain, breathlessness)
