J-pouch surgery is a surgical treatment for ulcerative colitis. Doctors may recommend J-pouch surgery when medications and other treatment methods are not effective.
Doctors may also refer to a J-pouch as a proctocolectomy with ileal pouch anal-anastomosis (IPAA). During the surgery, a surgeon removes a person’s colon and rectum before creating an internal pouch from the lower intestine. This pouch connects to the anus, allowing a person to pass stool without the need for a colostomy bag.
It is the most common surgical intervention for ulcerative colitis (UC) – an inflammatory bowel disease (IBD) that causes chronic inflammation and ulcers in the colon and rectum.
This article explores what a person can expect during and after J-pouch surgery. It will also consider the advantages and drawbacks of this technique compared to other ostomy procedures, explaining any potential complications and the recovery time for people undergoing this procedure.
During the procedure, a surgeon first removes the colon and rectum before creating a pouch shaped like the letter J out of the end of the small intestine. The J-pouch works as an alternative method of allowing bowel movements.
J-pouch surgery can occur in one to three stages, depending on the health of the individual:
Stage 1
In the first surgery, a surgeon will remove the colon and rectum. The anus and anal sphincter muscles will remain in place.
The surgeon will form a J-shaped pouch from the ileum, a section of the small intestine, and connect it to the top of the anal canal.
They may create a temporary ileostomy, which opens the abdomen to allow part of the small intestine outside the abdominal wall. This creates an opening for waste to leave the body into an external pouch, called an ostomy bag.
People need to wear the ostomy bag for the duration of healing and empty it throughout the day.
Stage 2
Once the J-pouch heals, individuals will have their second surgery, which may be 8 to 12 weeks after the first.
During the second stage, a surgeon will remove the temporary ileostomy and reattach the small intestine. The J-pouch will now be able to help the body remove waste through the anus during bowel movements.
In some cases, a surgeon may carry out stages 1 and 2 in one surgery without creating a temporary ileostomy. However, this is less common because of an increased risk of infection.
Stage 3
People may have a three-stage process if they:
- have additional health issues
- are taking high doses of steroids
- require emergency surgery for bleeding or toxic megacolon
Toxic megacolon is rare but life threatening — it happens when a person’s
In the first surgery, a surgeon will remove the colon and form an ileostomy. In the second surgery, a surgeon will remove the rectum, form the ileum into a J-pouch, and connect the pouch to the anus.
In the third surgery, 8 to 12 weeks after the second surgery, a surgeon will remove the ileostomy and attach the small intestine to the J-pouch.
J-pouch surgery can have a profound, positive effect on a person’s life. It removes the long-term need for an ostomy bag and provides the ability to pass stool the usual way instead of through a stoma.
In addition, J-pouch surgery often reduces the number of medications a person needs to take. After the procedure, many people with UC will no longer have the same level of pain, urgency, and diarrhea associated with colitis.
Benefits of J-pouch surgery include:
- People can continue to have bowel movements through the anus.
- Apart from possible abdominal scarring, a J-pouch is not visible to others.
- People may find it easier to choose clothing that fits and feels comfortable rather than fitting it around a stoma over the long term.
- J-pouch surgery involves less maintenance, as a person will not need to change a stoma bag after the healing is complete.
- Up to 50% of people with stomas may experience long-term issues, such as:
- hernias
- prolapse
- bowel obstruction
- bag leakage
- skin irritation
- dehydration
Disadvantages of J-pouch surgery include:
- J-pouch surgery requires more surgery than a stoma.
- J-pouch surgery involves major surgery, which can cause complications.
- There is a risk of developing pouchitis, an inflammation of the pouch.
- Some may experience sexual dysfunction due to nerve damage, such as painful intercourse or ejaculation problems.
- Females may have scar tissue around the ovaries and fallopian tubes, which could affect fertility.
Complications
People will need emergency medical attention if they experience any of the following complications following J-pouch surgery:
Pouchitis
Pouchitis is an inflammation of the J-pouch. Up to 50% of people may develop this complication in the 2 years following surgery. Symptoms include:
Doctors can treat pouchitis with antibiotics.
Anastomotic leak or stricture
An anastomotic leak can occur if the contents of the intestine leak through the site of the anastomosis, where the small intestine joins the rectum. It could also acquire an infection and be fatal. A person may require additional surgery and hospital stays.
Anastomotic stricture develops when the anastomotic site becomes narrowed, which may require additional surgery to repair.
Small bowel obstruction
Adhesions, which are bands of scar-like tissue, can join organs and tissues together, which may lead to small bowel obstruction. Symptoms include:
- abdominal pain or cramps
- nausea and vomiting
- unable to make bowel movements or pass gas
In some cases, resting the bowels through IV fluids and avoiding eating for a few days may treat small bowel obstruction. In other cases, people may require surgery.
Failure rate
The risk of an ileal pouch failing is around 5 to 15% for people with ulcerative colitis. If a pouch fails, people may need to revert to using a stoma.
Reasons for J-pouch failure can include:
- a change in diagnosis from ulcerative colitis to Crohn’s disease
- fistulae
- pelvic sepsis
J-pouch surgery is a major undertaking, and the body will need time to recover. It is important to work with healthcare providers to manage the recovery process, understand recovery timelines, and start making necessary lifestyle changes.
People may experience the following after having J-pouch surgery:
- Increased bowel movements: A person may experience up to 12 to 15 bowel movements each day, which decreases once they leave the hospital to around 4 to 6 a day.
- Rectal drainage: Mucus may seep out through the anus, but this is a temporary side effect until the ileostomy closes.
- Irritation of the skin around the anus: People can manage this with skin care and by avoiding certain foods, such as spicy foods, tea, and coffee, which may increase irritation.
- Some seepage or incontinence: A person may notice seepage or incontinence, particularly at nighttime, which will usually resolve over time.
- Irregular menstrual cycle: If people menstruate, they may have an irregular menstrual cycle for up to a year following the operation.
Postsurgical care
People need to follow post-surgical care instructions from a healthcare professional. This may include:
- protecting the skin around the anus with proper skin care to prevent irritation
- drinking plenty of fluids to prevent dehydration and the risk of obstruction
- eating a low fiber diet for around 4 weeks and then gradually increasing fiber
- only resuming sexual activity when safe
- eating foods high in potassium to help with diarrhea, such as bananas, sweet potato, and oranges
- eating moderate amounts regularly and chewing food thoroughly
The outlook for people undergoing J-pouch surgery is positive. If the surgery is without complications and a person follows their postoperative plan well, they will be able to slowly return to normal activity.
Long-term, people will be able to live largely as they did before the surgery.
People are under general anaesthetic during J-pouch surgery to will not feel pain from the procedure itself.
However, it is a major operation and pain after waking up is normal. The pain will vary according to an individual’s pain response and how the body responds to pain medication.
The first stage of J-pouch surgery may take 2 to 4 hours. The follow up second and third stages may occur 8 to 12 weeks later and take around one hour.
J-pouch surgery is a treatment method for ulcerative colitis. Doctors can carry out the procedure over the course of one to three operations.
First, a surgeon removes the colon and rectum. They then create a J-shaped pouch with the end of the small intestine. The J-pouch replaces the colon and rectum to allow waste to pass out through the anus.
People can discuss the benefits and risks of J-pouch surgery and what to expect during and after the procedure with their healthcare professional.
