Private hemicolectomy in the UK, by a consultant colorectal surgeon.
Indicative pricing
What a private hemicolectomy costs in the UK.
Indicative ranges across UK private providers. Hemicolectomy is NHS-funded for eligible patients - private figures below are all-inclusive of surgeon, anaesthetist, theatre and inpatient stay.
In short
£15,000–£22,000 all-in, home in three to five days.
| Procedure | Indicative range | Typical duration | Recovery |
|---|---|---|---|
| Right hemicolectomy (laparoscopic) | £15,000–£22,000 | 2–3 hours | 3–5 days inpatient |
| Left hemicolectomy (laparoscopic) | £17,000–£25,000 | 2.5–4 hours | 4–7 days inpatient |
| Extended right or left hemicolectomy | £20,000–£28,000 | 3–4 hours | 5–7 days inpatient |
| Robotic hemicolectomy | £22,000–£30,000 | 3–4 hours | 3–6 days inpatient |
| Open hemicolectomy | £15,000–£24,000 | 2–3 hours | 5–10 days inpatient |
| Outpatient colorectal consultation | £250–£450 | 30–45 min | Same visit |
Prices vary by hospital, by which surgeon leads the case, by approach (open, laparoscopic or robotic), by length of stay and by whether adjuvant chemotherapy or a stoma reversal follows.
The problem
The right surgeon, the right hospital, the right approach.
Hemicolectomy outcomes vary more by surgeon volume and MDT quality than by anything else.
-
Keyhole where possible?
Laparoscopic or robotic when appropriate; open when it is genuinely the safer choice. Your surgeon should explain both.
When it helps
When hemicolectomy is the right operation.
The indications we see most, plus the one situation where the answer is A&E - not a booking form.
-
Colorectal cancer (right or left colon)
The most common reason - a tumour in the caecum, ascending, transverse, splenic flexure or descending colon needing curative resection.
-
Polyps that cannot be removed endoscopically
A large or awkwardly placed polyp with high-grade dysplasia where colonoscopic resection is not safe or complete.
-
Complicated diverticular disease
Recurrent diverticulitis, stricture, fistula or an abscess that has not settled with conservative management.
-
Crohn’s disease of the terminal ileum or colon
Isolated ileocolic Crohn’s with stricture, fistula or medication failure - often treated by a right hemicolectomy.
-
Colonic ischaemia
Non-viable bowel from vascular compromise, sometimes needing urgent resection with or without a stoma.
-
Large-bowel obstruction
An obstructing tumour or stricture where a stent has failed or is not appropriate - resection is the definitive treatment.
-
Bleeding that will not settle
Persistent lower gastrointestinal bleeding from a localised colonic source that has failed endoscopic and radiological treatment.
-
Red flag: perforation or sepsis
Peritonitis, free perforation or septic shock is an emergency admission - not something to arrange privately from home.
Procedure options
Right, left, extended - and open or keyhole.
What each option actually involves - and which fits which case. Sigmoid colectomy and total colectomy are separate operations, covered on their own pages.
-
Right hemicolectomy
The commonest colorectal resection - caecum, ascending colon, hepatic flexure and proximal transverse colon are removed and an ileocolic anastomosis fashioned.
-
Extended right hemicolectomy
Extends the right hemicolectomy into the mid or distal transverse colon, usually for lesions at or near the splenic flexure.
-
Left hemicolectomy
Removes the distal transverse, splenic flexure and descending colon, with a colo-colic or colo-sigmoid anastomosis.
-
Extended left hemicolectomy
A left hemicolectomy that continues into the sigmoid - chosen when the tumour or disease extends distally.
-
Laparoscopic (keyhole) approach
Four or five small incisions and a short extraction wound. Less pain, quicker recovery, and now the default in the UK where feasible.
-
Robotic-assisted approach
A surgeon-controlled robotic platform used for a minimally-invasive resection - increasingly available in UK private colorectal units.
-
Open hemicolectomy
A midline incision when laparoscopy is not appropriate - large tumour, dense adhesions, emergency setting, or a haemodynamically unstable patient.
-
Consultation only
A second opinion and a proper discussion of whether hemicolectomy is the right operation, and how it would be done for you.
Safety and recovery
What to expect afterwards - honestly.
Hemicolectomy is a major operation with a well-defined risk profile. Elective 30-day mortality is 1–3%, higher in emergency cases. Long-term outcomes depend more on stage than on approach.
-
Anastomotic leak
Roughly 3–8% of hemicolectomies, higher after left than right. Diagnosed early with a CT and treated with drainage, re-operation or a stoma depending on severity.
-
Ileus and slow return of bowel function
A common, self-limiting hold-up in the first few days - the ERAS pathway (early mobilisation, chewing gum, no NG tube) is designed to shorten it.
-
Wound infection and incisional hernia
Wound infection in 5–15%; incisional hernia in up to 10–20% at five years - lower with laparoscopic than open surgery.
-
Bleeding, DVT, PE and cardiac events
Uncommon with VTE prophylaxis and modern anaesthesia, but always discussed as part of consent - particularly if you have cardiac or respiratory disease.
-
Stoma - usually not needed
Most elective right hemicolectomies avoid a stoma. Some left-sided resections with a low anastomosis need a temporary loop ileostomy; reversal is a separate operation.
-
Long-term bowel habit
Looser stools and more frequent bowel motions are normal for weeks to months. Most people settle back to a new normal within six months.
-
Autonomic nerve injury
Rare in right or left hemicolectomy - more relevant for very low pelvic surgery. Discussed in detail if your resection extends into the sigmoid or rectum.
-
Adjuvant chemotherapy where indicated
Stage III cancers and high-risk stage II cancers are usually offered three to six months of FOLFOX or CAPOX per NICE guidance, starting within about eight weeks of surgery.
-
Red flags after discharge
Fever, worsening abdominal pain, vomiting, no wind or stool, or a wound that is red and weeping - call the ward or 999 the same day.
Reading your operation note
Your operation note in four parts. Read the last one first.
Whichever approach was used - laparoscopic, robotic or open - the note the surgeon sends you keeps to the same shape.
A quiet reminder
Surgical and pathology language is precise and can read coldly - we translate it for you.
If you would like us to talk you through the operation note and histology before your MDT clinic, just ask.
- 01 Header
Indication and operation performed
Why the resection was done - tumour, polyp, Crohn’s, diverticular disease - and whether it was a right, extended right, left or extended left hemicolectomy.
- 02 Technique
Approach, CME and anastomosis
Laparoscopic, robotic or open. Whether complete mesocolic excision with central vascular ligation was achieved. How the join was made - stapled or hand-sewn - and whether a stoma was fashioned.
- 03 Findings
Intra-operative findings and histology
Any peritoneal disease, liver surface findings, node yield and margins. The formal pathology (TNM stage, differentiation, lymphovascular invasion, MMR status) follows in about two weeks.
- 04 Impression
Recovery plan and MDT next steps
Read this first: expected ward stay, ERAS milestones, follow-up clinic date, whether adjuvant chemotherapy is being considered, and the surveillance plan.
Recognised by major UK insurers
Hemicolectomy is normally covered by UK private medical insurance when medically indicated.
Frequently asked
Everything patients ask about hemicolectomy.
Quick answers on the operation, stomas, recovery time, chemotherapy and follow-up.
-
Why has a hemicolectomy been recommended for me?
The commonest reason is colorectal cancer - around 40% of colorectal cancer resections in the UK are right hemicolectomies. Other indications are polyps that cannot be removed endoscopically, complicated diverticular disease, ileocolic Crohn’s disease, colonic ischaemia, obstruction and bleeding. Your MDT letter should say why yours has been offered.
-
What is the difference between a right and a left hemicolectomy?
A right hemicolectomy removes the caecum, ascending colon, hepatic flexure and proximal transverse colon, joining the small bowel to the remaining colon (an ileocolic anastomosis). A left hemicolectomy removes the distal transverse, splenic flexure and descending colon, joining the two remaining ends of colon together (a colo-colic anastomosis). Extended versions go further along the transverse or into the sigmoid.
-
Will I need a stoma?
Usually not, for elective right hemicolectomy. A minority of left-sided resections with a low anastomosis need a temporary loop ileostomy to protect the join - typically reversed after eight to twelve weeks. Emergency operations for perforation or obstruction more often need a stoma. A stoma nurse is involved from the start if one is planned.
-
Is it done by keyhole?
In the UK, more than 70% of elective hemicolectomies are laparoscopic, per the National Bowel Cancer Audit. Robotic surgery is increasing. Open surgery is chosen when the tumour is very large, there are dense adhesions, the case is an emergency, or the patient is unstable. Your surgeon should explain which fits your case and why.
-
How long will I be in hospital and off work?
Typical hospital stay is three to seven days on an ERAS pathway. Most desk-based workers return in four to six weeks; heavy manual jobs need eight to twelve. No heavy lifting for six to eight weeks. Driving usually restarts at four to six weeks when you can perform an emergency stop without hesitation.
-
What are the main risks?
Anastomotic leak (3–8%, higher after left than right hemicolectomy), ileus, bleeding, wound infection (5–15%), incisional hernia (10–20% at five years), adhesive obstruction long term, DVT or PE, cardiac events, and - for lower resections - a change in bowel habit. Thirty-day mortality is 1–3% for elective surgery, higher in emergencies.
-
Will I need chemotherapy after?
Adjuvant chemotherapy - usually FOLFOX or CAPOX for three to six months - is offered to Stage III colorectal cancers and to high-risk Stage II cancers, per NICE guidance. It normally starts within eight weeks of surgery. Your MDT decides based on the final pathology.
-
What does follow-up look like?
Six-monthly CT chest, abdomen and pelvis plus CEA for the first three years, then annually to five years. A surveillance colonoscopy at one year (unless a clearance colonoscopy was already done pre-op), then every three to five years per BSG guidance. Your surgeon or oncologist coordinates this.
