Large bowel resection is surgery to remove all or part of your large bowel. This surgery is also called colectomy. The large bowel is also called the large intestine or colon.

  • Removal of the entire colon and the rectum is called a proctocolectomy.
  • Removal of all of the colon but not the rectum is called subtotal colectomy.
  • Removal of part of the colon but not the rectum is called a partial colectomy.

The large bowel connects the small intestine to the anus. Normally, stool passes through the large bowel before leaving the body through the anus.

Description

You’ll receive general anesthesia at the time of your surgery. This will keep you asleep and pain-free.

The surgery can be performed laparoscopically or with open surgery. Depending on which surgery you have, the surgeon will make one or more cuts (incisions) in your belly.

If you have laparoscopic surgery:

  • The surgeon makes 3 to 5 small cuts (incisions) in your belly. A medical device called a laparoscope is inserted through one of the cuts. The scope is a thin, lighted tube with a camera on the end. It lets the surgeon see inside your belly. Other medical instruments are inserted through the other cuts.
  • A cut of about 2 to 3 inches (5 to 7.5 centimeters) may also be made if your surgeon needs to put his or her hand inside your belly to feel or remove the diseased bowel.
  • Your belly is filled with gas to expand it. This makes the area easier to see and work in.
  • The surgeon examines the organs in your belly to see if there are any problems.
  • The diseased part of your large bowel is located and removed. Some lymph nodes may also be removed.

If you have open surgery:

  • The surgeon makes a cut of 6 to 8 inches (15 to 20 centimeters) in your lower belly.
  • The organs in your belly are examined to see if there are any problems.
  • The diseased part of your large bowel is located and removed. Some lymph nodes may also be removed.

In both kinds of surgery, the next steps are:

  • If there is enough healthy large intestine left, the ends are stitched or stapled together. This is called an anastomosis. Most patients have this done.
  • If there is not enough healthy large intestine to reconnect, the surgeon makes an opening called a stoma through the skin of your belly. The colon is attached to the outer wall of your belly. The stool will go through the stoma into a drainage bag outside your body. This is called a colostomy. The colostomy may be either short-term or permanent.

Colectomy usually takes between 1 and 4 hours.

Why the Procedure Is Performed

Large bowel resection is used to treat many conditions, including:

  • A blockage in the intestine due to scar tissue
  • Colon cancer
  • Diverticular disease (disease of the large bowel)

Other reasons for bowel resection are:

  • Familial polyposis
  • Injuries that damage the large bowel
  • Intussusception (when one part of the intestine pushes into another)
  • Precancerous polyps
  • Severe gastrointestinal bleeding
  • Twisting of the bowel (volvulus)
  • Ulcerative colitis

Risks

Risks for anesthesia and surgery in general are:

  • Reactions to medicines
  • Breathing problems
  • Blood clots, bleeding, infection

Risks for this surgery are:

  • Bleeding inside your belly
  • Bulging tissue through the surgical cut, called an incisional hernia
  • Damage to nearby organs in the body
  • Damage to the ureter or bladder
  • Problems with the colostomy
  • Scar tissue that forms in the belly and causes a blockage of the intestines
  • The edges of your intestines that are sewn together come open (anastomotic leak, which may be life-threatening)
  • Wound breaking open
  • Wound infection

Before the Procedure

Tell your surgeon or nurse what medicines you are taking, even drugs, supplements, or herbs you bought without a prescription.

Talk with your surgeon or nurse about how surgery will affect:

  • Intimacy and sexuality
  • Pregnancy
  • Sports
  • Work

During the 2 weeks before your surgery:

  • You may be asked to stop taking drugs that make it harder for your blood to clot. These include aspirin, ibuprofen (Advil, Motrin), Naprosyn (Aleve, Naproxen), and others.
  • Ask the surgeon which drugs you should still take on the day of your surgery.
  • If you smoke, try to stop. Smoking increases the risk for problems such as slow healing. Ask your doctor or nurse for help quitting.
  • Tell the surgeon right away if you have a cold, flu, fever, herpes breakout, or other illness before your surgery.
  • You may be asked to go through a bowel preparation to clean your intestines of all stool. This may involve staying on a liquid diet for a few days and using laxatives.

The day before surgery:

  • You may be asked to drink only clear liquids such as broth, clear juice, and water.
  • Follow instructions about when to stop eating and drinking.

On the day of surgery:

  • Take the drugs your surgeon told you to take with a small sip of water.
  • Arrive at the hospital on time.

After the Procedure

You will be in the hospital for 3 to 7 days. You may have to stay longer if the colectomy was an emergency operation.

You may also need to stay longer if a large amount of your large intestine was removed or you develop problems.

By the second or third day, you will probably be able to drink clear liquids. Thicker fluids and then soft foods will be added as your bowel begins to work again.

Outlook (Prognosis)

Most people who have a large bowel resection recover fully. Even with a colostomy, most people are able to do the activities they were doing before their surgery. This includes most sports, travel, gardening, hiking, other outdoor activities, and most types of work.

If you have a long-term (chronic) condition, such as cancer, Crohn’s disease, or ulcerative colitis, you may need ongoing medical treatment.

 

Doctor visit helper

Prepare before seeing a doctor

A simple rural-patient checklist to help you explain symptoms clearly, ask better questions, and avoid unsafe self-treatment.

Safety note: This is not a prescription or diagnosis. For severe symptoms, pregnancy danger signs, children with serious illness, chest pain, breathing difficulty, stroke-like weakness, or major injury, seek urgent care.

Which doctor may help?

Start with a registered doctor or the nearest qualified health center.

What to tell the doctor

  • Write when the problem started and how it changed.
  • Bring old prescriptions, investigation reports, and current medicines.
  • Write allergies, pregnancy status, diabetes, kidney/liver disease, and major past illnesses.
  • Bring one family member if the patient is weak, elderly, confused, or a child.

Questions to ask

  • What is the most likely cause of my symptoms?
  • Which danger signs mean I should go to hospital quickly?
  • Which tests are necessary now, and which can wait?
  • How should I take medicines safely and what side effects should I watch for?
  • When should I come for follow-up?

Tests to discuss

  • Vital signs: temperature, pulse, blood pressure, oxygen saturation
  • Basic physical examination by a clinician
  • CBC, urine test, blood sugar, or imaging only when clinically needed

Avoid these mistakes

  • Do not use antibiotics, steroid tablets/injections, or strong painkillers without proper medical advice.
  • Do not hide pregnancy, kidney disease, ulcer, allergy, or blood thinner use.
  • Do not delay emergency care when danger signs are present.

Medicine safety and first-aid guide

This section is for patient education only. It does not replace a doctor, pharmacist, or emergency care.

Safe first steps

  • Drink safe fluids and monitor temperature.
  • In dengue-prone areas, discuss CBC and platelet count when fever persists or warning signs appear.
  • Use tepid sponging for high fever discomfort; avoid ice-cold bathing.

OTC medicine safety

  • For fever, common fever medicine may be discussed with a clinician or pharmacist.
  • Avoid aspirin/ibuprofen-like medicines in suspected dengue unless a doctor says it is safe.

Avoid these mistakes

  • Do not start antibiotics without a proper medical decision.
  • Do not use steroid tablets or injections casually for quick relief.
  • Do not delay emergency care because of home remedies.

Get urgent help if

  • Fever with breathing difficulty, confusion, repeated vomiting, bleeding, severe weakness, stiff neck, or dehydration needs urgent care.
Medicine names, dose, and timing must be decided by a qualified clinician or pharmacist after checking age, pregnancy, allergy, other diseases, and current medicines.

For rural patients and family caregivers

Patient health record and symptom diary

Write your symptoms, medicines already taken, test results, and questions before visiting a doctor. This note stays on your device unless you print or copy it.

Doctor to discuss: Medicine doctor / pediatrician for children / qualified clinician
Tests to discuss with doctor
  • Temperature chart and hydration assessment
  • CBC with platelet count if fever persists or dengue/other infection is possible
  • Urine test, malaria/dengue tests, chest evaluation, or blood culture only when clinically indicated
Questions to ask
  • What is the most likely cause of my symptoms?
  • Which warning signs mean I should go to emergency care?
  • Which tests are really needed now?
  • Which medicines are safe for my age, pregnancy status, allergy, kidney/liver/stomach condition, and current medicines?
  • Do I need antibiotics, or is this more likely viral?

Emergency warning signs such as chest pain, severe breathing difficulty, sudden weakness, confusion, severe dehydration, major injury, or loss of bladder/bowel control need urgent medical care. Do not wait for online information.

Safe pathway to proper treatment

Care roadmap for: Ascending colectomy; Descending colectomy; Transverse colectomy

Use this simple roadmap to understand the next safe steps. It is educational and does not replace examination by a doctor.

Go to emergency care if you notice:
  • Severe or rapidly worsening symptoms
  • Breathing difficulty, chest pain, fainting, confusion, severe weakness, major injury, or severe dehydration
Doctor / service to discuss: Qualified healthcare provider; specialist depends on symptoms and examination.
  1. Step 1

    Check danger signs first

    If danger signs are present, seek emergency care and do not wait for online information.

  2. Step 2

    Record the symptom story

    Write when symptoms started, severity, medicines already taken, allergies, pregnancy status, and test results.

  3. Step 3

    Visit a qualified clinician

    A doctor, nurse, or qualified healthcare provider can examine you and decide which tests or treatment are needed.

  4. Step 4

    Do only useful tests

    Do tests after clinical assessment. Avoid unnecessary tests, random antibiotics, or repeated medicines without diagnosis.

  5. Step 5

    Follow up and return early if worse

    If symptoms worsen, new warning signs appear, or treatment is not helping, return for review quickly.

Rural patient practical tips
  • Take a written symptom diary and all previous prescriptions/test reports.
  • Do not hide medicines already taken, even herbal or over-the-counter medicines.
  • Ask which warning signs mean urgent referral to hospital.

This roadmap is for education. A real diagnosis and treatment plan requires history, examination, and clinical judgment.
