Stricture rectal, also known as anal stenosis, refers to the abnormal narrowing of the rectum, the last part of the large intestine. This condition can occur due to a variety of reasons, including scar tissue formation, inflammation, or injury. The result is often challenging and painful defecation, as well as potential complications that may require intervention from medical professionals.
causes
- Inflammatory Bowel Disease (IBD): A chronic inflammatory condition that can affect the entire digestive tract, IBD can leads to scarring and strictures within the rectum.
- Hemorrhoidectomy: Sometimes, after a hemorrhoidectomy, patients may develop strictures due to the formation of scar tissue.
- Radiation Therapy: Patients who undergo radiation therapy for cancers in the pelvic region may develop strictures in the rectum or colon.
- Infection: Infection in the rectum can lead to the formation of scar tissue, resulting in stricture.
- Congenital Anomalies: Some children are born with an anomaly in the rectum, which can lead to strictures.
- Postoperative Complications: Strictures can also complicate surgical procedures, such as a colorectal resection for cancer.
Symptoms
Those with stricture rectal often experience:
- Difficulty Passing Stool: Stools may become small, hard, or pencil-shaped, making it difficult to evacuate completely.
- Painful Bowel Movements: Patients may experience discomfort or a sense of fullness during bowel movements.
- Bleeding: Some patients may notice bright red blood in their toilet after a bowel movement.
- Straining and Fecal Incontinence: These symptoms indicate that the anal muscles are experiencing increased tension, and the patient may struggle to control their feces.
- Obstructive Symptoms: Severe strictures can block the rectum, leading to bloating, nausea, and vomiting.
##Diagnosis
Diagnosing stricture rectal typically involves a physical examination, sigmoidoscopy or colonoscopy, and imaging tests such as X-rays, MRIs, or CT scans. These exams allow doctors to clearly visualize the rectum and assess the extent of the stricture.
##Treatment
Treatment for stricture rectal depends upon the severity and underlying cause of the condition. Some common treatments included:
-Antibiotics: Used to treat infections or inflammation.
-Fiber Supplements: Added to the diet to help soften stool and relieve constipation.
-Stool Softeners: Agents such as docusate sodium that help soften stool and make bowels move more easily.
-Dilators: Ingested orally or applied anally to gradually stretch the anal canal and facilitate rectal evacuation.
-Anal Sphincteromy: In some cases, a sphincterotomy may be performed to relax the anal sphincter muscle, which can be particularly useful in cases of post-hemorrhoidectomy strictures.
-Surgery: For severe strictures or complex cases, the patient may require anoplasty or other整形手术 to correct the issue.
-Assessment and Monitoring: In certain situations, regular assessment and monitoring by a healthcare professional may be necessary to detect changes in the condition.
It is crucial to consult with a healthcare professional if any signs or symptoms of stricture rectal develop. Early detection and treatment can prevent complications and improve quality of life.
