التعريف والنظرة العامة
Proctocolectomy is a surgical procedure recommended for people who require a rectum and colon resection. It partially or completely removes the colon and the rectum to treat familial adenomatous polyposis, Crohn’s disease, inflammatory bowel disease and ulcerative colitis. The procedure is irreversible and as such, is not recommended as the first line of treatment. It is only performed when medications and therapies have failed to manage the symptoms or when the disease has already significantly progressed.

Patients suffering from the following conditions can be considered for a proctocolectomy:
Familial adenomatous polyposis – This inherited condition involves the formation of adenomatous polyps in the epithelial tissue that lines the large intestine. Most of these polyps start out as benign growths, but when left untreated, they can become malignant and spread to the colon, which can lead to colon cancer. Removing sections of the large intestine through a rectum and colon resection surgery can keep the malignant polyps from invading the colon.
Inflammatory bowel disease. Also known as IBD, this term actually refers to various conditions that cause inflammation in the colon (a section of the large intestine) and the small intestine. Inflammatory bowel diseases include Crohn’s disease and ulcerative colitis. This group of conditions results in key symptoms such as bleeding of the rectum, abdominal pain, diarrhea, vomiting, severe weight loss, فقر دم, and severe spasms or cramps in the abdominal and pelvic area. Medications and other forms of non-invasive therapy are first prescribed to the patient, with a rectum and colon resection being the last resort should the symptoms and condition fail to respond to the first line of treatment.
كيف يعمل هذا الإجراء؟
Proctocolectomy is performed under general anaesthesia, which means that the patient is asleep and will not feel pain during the whole procedure. The surgeon will then make an incision in the lower belly to access the bowels. The large intestine (whether in parts or completely) and the rectum will then be removed. For patients with colon or bowel cancer, the surgeon might also remove some lymph nodes to prevent cancer from spreading to other organs.
A proctocolectomy is often performed with an ileostomy, where the end of the large intestine is pulled into an incision in the lower right part of the abdomen. This end will be sewn in place to create an opening called a stoma, where the stool can come out. A drainage bag will be attached to the stoma for stool collection.
Depending on the severity of the condition, the patient might be required to stay up to two weeks in the hospital following the procedure for close monitoring.
المخاطر والمضاعفات المحتملة
The procedure itself is generally safe, but it is irreversible, which means that careful consideration must be undertaken both by the medical team and the patient before it is performed.
The ileostomy is the leading source of post-procedure complications, including infection, because of the stoma.
Thirty percent of patients who have undergone proctocolectomy have developed an infection after the operation. Fifteen percent experienced bowel obstruction while thirty percent have had trouble with the stoma. Twenty to 25 percent of patients have required additional surgery to repair the complications and adverse side effects of the stoma.
Other side effects include the formation of blood clots in the legs (which can travel to the patient’s lungs), السكتة الدماغية, heart attack, breathing problems, abdominal hemorrhage, damage to the pelvic nerves and organs, infections in the abdominal cavity, and urinary tract obstruction.

What is Proctocolectomy? Overview, Benefits, and Expected Results
Proctocolectomy is a surgical procedure that removes the rectum and the colon. It is commonly used to treat bowel diseases like inflammatory bowel disease (IBD) and ulcerative colitis (UC). The procedure may also be recommended to treat colorectal cancer, digestive obstruction, fistulas, or other complications from diseases of the rectum or colon. It is usually performed laparoscopically, using instruments inserted through small incisions in the abdomen, and requires general anesthesia.
What is a Proctocolectomy?
A proctocolectomy is a major surgical operation to remove the entire rectum and part or all of the colon. The procedure involves cutting the rectum away from the surrounding organs, and removing the rectum, colon, and attached tissues and lymph nodes.
In some cases, the surgeon may need to remove part of the small intestine or close the small intestine off from the colon and rectum. This is to ensure all traces of cancer or infection are removed. After the procedure, a pouch is usually created using the small intestine; this is referred to as an ileal pouch-anal anastomosis (IPAA). The resulting surgical procedure is called a “restorative proctocolectomy” because it is restoring the normal anatomy and function of the digestive system.
Benefits of Proctocolectomy
Proctocolectomy can offer many benefits to those suffering from certain diseases or conditions of the rectum or colon. It can provide significant relief from symptoms and may even lead to a complete cure of the underlying condition. The procedure may also be used to reduce the risk of future complications.
- Considered the gold standard of treatment for ulcerative colitis and indeterminate colitis.
- Improves digestive health by removing the affected parts of the intestine, thus eliminating complications like obstruction, diverticulitis, and fistulas.
- The ileal pouch-anal anastomosis (IPAA) created after a total proctocolectomy seals off the danger of future rectal tumors.
- Reduces the risk of colorectal cancer, especially in cases of familial adenomatous polyposis or hereditary nonpolyposis colorectal cancer.
- Reduces the risk of perianal inflammation and abscesses associated with IBD.
The success rate of proctocolectomy is generally good; many patients experience long-term remission or cure of their conditions. In many cases, an improvement in quality of life is seen, with a decrease in symptoms and the risk of future complications being reduced.
However, the results vary depending on the underlying condition. Ulcerative colitis patients have the best chance of seeing successful results with up to 80% achieving long-term remission. Patients with familial adenomatous polyposis have the lowest success rate, with up to 40% being non-responsive and requiring other treatments.
Recovery After Proctocolectomy
Recovery from a proctocolectomy usually takes anywhere from 8-12 weeks. During this time, the patient should rest at home and avoid strenuous activity. Pain medication may be prescribed, and it is important to stay hydrated and eat a balanced diet. If an ileal pouch-anal anastomosis was created, additional steps must be taken to ensure the pouch functions properly. This includes taking stool softeners to reduce the risk of straining during bowel movements.
As with any major surgery, there is a risk of complications following a proctocolectomy. Possible complications include bleeding, infection, hernia formation, and reaction to anesthesia. It is also possible for the newly-created ileal pouch to become blocked or to leak. In rare cases, complications can be life-threatening, so it is important to talk to your doctor or surgeon about any possible risks associated with the procedure.
Proctocolectomy is a major surgical procedure used to treat conditions of the rectum, colon, and small intestine. It is considered the gold standard in treating ulcerative colitis or indeterminate colitis, and can reduce the risk of colorectal cancer in certain cases. The success rate is generally good, and recovery times can be up to 12 weeks. Possible complications are associated with the procedure, and it is important to talk to your doctor or surgeon about any risks.
