Colorectal Surgery

Colorectal Surgery - Central Coast

As a specialist in colorectal surgery, Dr Peter Stewart provides expert care for conditions affecting the bowel, rectum, and anus. He manages both routine and complex cases, from colonoscopy and polyp removal to bowel cancer surgery and treatment of inflammatory bowel disease (IBD), haemorrhoids, and anal fissures.

With a strong focus on minimally invasive techniques and personalised care, his goal is to ensure the best possible outcomes while supporting patients through every step of their treatment.

Conditions Treated

Patients are referred for colorectal care for a range of reasons, from common symptoms to complex bowel or anal conditions. Dr Stewart treats both benign and malignant diseases, working closely with each patient to determine the most appropriate course of action.

Diagnosis and surgical management of colorectal cancer, including laparoscopic bowel resection where appropriate.

Assessment and surgical options for managing faecal incontinence.
Surgical and non-surgical treatment of painful or bleeding haemorrhoids.

Surgical & Endoscopic Procedures

A variety of surgical and endoscopic procedures are used to diagnose and treat colorectal conditions. Where appropriate, minimally invasive (laparoscopic) techniques are preferred to support faster recovery, reduce pain, and achieve better outcomes.

Every treatment plan is tailored to the individual, taking into account the diagnosis, medical history, and personal goals.

Procedures include:
  • Laparoscopic bowel resection - Removal of diseased sections of the colon or rectum using keyhole surgery, often for cancer, diverticulitis, or IBD.
  • Colonoscopy - A diagnostic and therapeutic procedure used to examine the large bowel and remove polyps or take biopsies. Dr Stewart is GESA-accredited to perform colonoscopy and upper endoscopy.
  • Polypectomy - Removal of polyps during colonoscopy to reduce cancer risk.
  • Haemorrhoidectomy - Surgical removal of haemorrhoids that are large, painful, or not responding to other treatments.
  • Fistula repair and fistulotomy - Treatment for anal fistulas to resolve infection and prevent recurrence.
  • Rectopexy - A surgical procedure to correct rectal prolapse and restore normal bowel function.
  • Stricture repair - Widening or resection of narrowed segments of the bowel due to inflammation or scarring.

What to Expect From Your Colorectal Care

Dr Stewart aims to provide a clear, supportive experience from your first consultation through to recovery. Here’s what you can expect at each stage of your care:

Your first appointment will involve a detailed discussion about your symptoms, medical history, and any prior investigations. Dr Stewart will explain any concerns, outline the next steps, and answer your questions.

Further tests such as blood work, imaging (e.g. CT scan), or a colonoscopy may be recommended to confirm a diagnosis. Dr Stewart performs colonoscopy and upper endoscopy where appropriate to assist with accurate assessment.

Once a diagnosis is confirmed, Dr Stewart will discuss your treatment options, including whether surgery is necessary. Where possible, minimally invasive techniques will be used to reduce recovery time and discomfort.

If surgery is required, Dr Stewart will perform the procedure at one of three private hospitals on the Central Coast. You will be given pre-operative instructions and have the opportunity to ask questions before the day of surgery.
Post-operative care includes follow-up appointments to monitor your recovery, manage any concerns, and discuss results. You’ll receive clear advice on wound care, diet, activity, and when to return to work or normal routines.
