A full range of colorectal and general surgical procedures — with a strong preference for minimally invasive techniques, and every treatment plan tailored to the individual. Find your procedure below for clear information on what's involved, recovery, and what to expect.
Procedure
A flexible fibreoptic instrument is passed through the anus to examine the entire large bowel (colon and rectum).
Learn more →Procedure
Uses the same flexible fibreoptic instrument as colonoscopy, but examines only the left side of the colon (rectum and sigmoid colon).
Learn more →Procedure
Upper endoscopy to examine the oesophagus, stomach and duodenum. Used to investigate reflux, dysphagia, iron deficiency anaemia and upper GI symptoms.
Learn more →Procedure
Polyps identified during colonoscopy are removed using a snare wire or biopsy forceps (polypectomy).
Learn more →Procedure
A thin, flexible catheter with pressure sensors is gently inserted into the rectum to measure sphincter pressures at rest and during squeezing and straining.
Learn more →Procedure
A specialised ultrasound probe is gently inserted into the anal canal to generate high-resolution images of the internal and external anal sphincter muscles.
Learn more →Procedure
Laparoscopic and robotic-assisted techniques are used for curative resection of colorectal cancer in appropriate patients.
Learn more →Procedure
Performed robotically using the Da Vinci platform, TAMIS allows precise resection of large rectal polyps or small rectal tumours through the anus, without abdominal incisions.
Learn more →Procedure
Robotic-assisted surgery uses the Da Vinci system — a surgeon-controlled robotic platform — to perform precise, minimally invasive operations.
Learn more →Procedure
Endoscopic placement of a self-expanding metal stent (SEMS) across an obstructing colorectal cancer or stricture.
Learn more →Procedure
Most diverticular disease is managed medically, but recurrent or complicated diverticulitis — including perforation, abscess or stricture — may require laparoscopic sigmoid colectomy.
Learn more →Procedure
Removal of the right colon (caecum, ascending colon and hepatic flexure) for right-sided cancer or large complex polyps.
Learn more →Procedure
Resection of the sigmoid colon and rectum for upper, mid or lower rectal cancer.
Learn more →Procedure
Surgery for low rectal cancer where sphincter-sparing resection is not possible.
Learn more →Procedure
Robotic fixation of the prolapsed rectum to the sacrum for full-thickness rectal prolapse.
Learn more →Procedure
Removal of most of the large bowel, leaving the rectum.
Learn more →Procedure
Removal of a diseased segment of small intestine for Crohn's disease, tumours, ischaemia or obstruction.
Learn more →Procedure
Reversal of a temporary defunctioning loop ileostomy formed at the time of anterior resection or other colorectal surgery.
Learn more →Procedure
The most effective and commonly performed procedure for internal haemorrhoids.
Learn more →Procedure
Formal surgical excision of haemorrhoids under general anaesthetic.
Learn more →Procedure
A Doppler probe identifies the haemorrhoidal arteries supplying the haemorrhoid, which are then tied off (ligated) via a specially designed proctoscope.
Learn more →Procedure
A radiofrequency ablation technique using a small probe inserted into the haemorrhoidal tissue to deliver controlled radiofrequency energy, shrinking the haemorrhoid.
Learn more →Procedure
An acute perianal abscess is a surgical emergency requiring prompt drainage.
Learn more →Procedure
Sphincter-preserving repair for complex and high anal fistulas, covering the internal opening with healthy rectal tissue.
Learn more →Procedure
The definitive treatment for simple, low anal fistulas.
Learn more →Procedure
A seton is a surgical thread or vessel loop passed through the fistula tract and secured as a loop.
Learn more →Procedure
Botulinum toxin (Botox) is injected into the internal anal sphincter under sedation to reduce sphincter spasm and improve blood flow to the fissure, promoting healing.
Learn more →Procedure
A minor surgical procedure performed under general or spinal anaesthetic for chronic anal fissure.
Learn more →Procedure
A comprehensive examination of the anus, anal canal, and lower rectum performed under general anaesthetic.
Learn more →Procedure
A minimally invasive, reversible treatment for faecal incontinence and urgency unresponsive to conservative measures.
Learn more →Procedure
Overlapping repair of a structurally deficient external anal sphincter, typically caused by an obstetric tear or prior anal surgery.
Learn more →Procedure
Inguinal hernias are generally repaired laparoscopically using the eTEP (extended totally extraperitoneal) technique — a minimally invasive approach placing mesh in the preperitoneal space without entering the abdominal cavity.
Learn more →Procedure
An incision is made directly over the hernia to repair the defect.
Learn more →Procedure
Incisional and ventral hernias (umbilical, paraumbilical, epigastric) are assessed individually.
Learn more →Procedure
For large or complex hernias — particularly recurrent hernias, giant ventral hernias, or those with significant loss of domain — formal abdominal wall reconstruction may be required.
Learn more →Procedure
Repair of a hernia developing around a stoma site — a common complication affecting up to 50% of patients with a permanent stoma.
Learn more →Procedure
Keyhole removal of the gallbladder for symptomatic gallstones or gallbladder disease.
Learn more →Procedure
Removal of benign or suspicious skin lumps (lipomas, epidermoid cysts, skin tags, moles, sebaceous cysts).
Learn more →Procedure
Keyhole removal of the appendix for acute or recurrent appendicitis, with a rapid recovery and small incisions.
