Stapled Transanal Resection of the Rectum (STARR)
Stapled Transanal Resection of the Rectum (STARR)
Rectal prolapse is very common in elderly women, although it may present at any age and in both male and female. It is generally not a life-threatening situation, but the symptoms can be very frustating. Surgical treatment of rectal prolapse is possible and most of the external prolapse can be treated by surgery successfully, often with a minimally invasive surgical procedure. Internal prolapses are traditionally harder to treat and traditional surgery may not be suitable for many patients.
Rectal prolapse is a very common problem and it may exist without any other symptoms, but depending upon the nature of the rectal prolapse there may be feeling of something coming out of anus, mucous discharge, rectal bleeding, ulceration and degrees of fecal incontinence and obstructed defecation symptoms.
Stapled Transanal Resection of the Rectum (STARR) is a surgical procedure used to treat chronic constipation and fecal incontinence. It involves the removal of excess rectal tissue using a circular stapler device. The procedure is relatively new and has gained popularity as an alternative to more invasive surgical procedures. In this essay, we will discuss the STARR procedure, its indications, technique, and outcomes.
Indications for STARR:
The STARR procedure is indicated for patients with chronic constipation or fecal incontinence due to rectal prolapse or rectocele. These conditions occur when the rectal wall becomes weak or damaged, causing the rectum to protrude into the anal canal or vagina. This can lead to difficulty with bowel movements, incomplete evacuation, and fecal incontinence. The STARR procedure is intended to remove the excess tissue and restore the normal anatomy of the rectum.
The STARR procedure is not suitable for all patients with chronic constipation or fecal incontinence. Patients with severe comorbidities or those who have previously undergone pelvic surgery may not be candidates for the procedure. Additionally, patients with a history of radiation therapy or inflammatory bowel disease may have a higher risk of complications and may not be suitable candidates.
Technique of STARR:
The STARR procedure is typically performed under general anesthesia and involves the use of a circular stapling device. The procedure is performed transanally, meaning that it is done through the anus without the need for abdominal incisions.
The procedure begins with the insertion of a proctoscope, a thin tube with a light and camera, into the rectum. The surgeon then uses the proctoscope to visualize the rectal prolapse or rectocele and to identify the excess tissue that needs to be removed.
The stapling device is then inserted through the proctoscope and placed around the excess tissue. The device consists of two circular rings that are joined by a stapling mechanism. The stapling mechanism fires multiple staples around the excess tissue, cutting and removing it in the process.
After the excess tissue has been removed, the stapling device is removed, and the proctoscope is used to examine the surgical site. The procedure typically takes around 45-60 minutes to perform.
Outcomes of STARR:
The STARR procedure has been shown to be effective in treating chronic constipation and fecal incontinence due to rectal prolapse or rectocele. A systematic review and meta-analysis of 26 studies involving 1800 patients found that the procedure resulted in significant improvements in bowel function and quality of life, with a low risk of major complications. The studies included in the review reported a success rate ranging from 56% to 100%.
The success of the STARR procedure appears to be dependent on several factors, including the severity of the prolapse or rectocele, the amount of tissue removed, and the experience of the surgeon. A study of 50 patients who underwent the STARR procedure found that the success rate was significantly higher in patients who had a shorter duration of symptoms and a smaller amount of tissue removed.
Complications of STARR:
Although the STARR procedure is generally safe, it can be associated with a range of complications. The most common complications include bleeding, infection, and pain. Other potential complications include:
Rectal perforation: This can occur if the stapling device is not placed correctly or if the rectal wall is weakened or damaged. Rectal perforation can lead to bleeding, infection, and the need for additional surgery.
Anal stenosis: This can occur if the stapling device causes scarring or narrowing of the anal canal. Anal stenosis can lead to difficulty with bowel movements and mayrequire additional surgery to correct.
Fecal incontinence: Although the STARR procedure is intended to treat fecal incontinence, it can sometimes lead to temporary or permanent worsening of symptoms.
Urinary retention: This can occur if the stapling device damages the nerves or muscles that control bladder function. Urinary retention can lead to difficulty with urination and may require additional treatment.
Sexual dysfunction: This can occur if the stapling device damages the nerves or blood vessels that supply the genitals. Sexual dysfunction can lead to difficulty with sexual function and may require additional treatment.
Conclusion:
Stapled Transanal Resection of the Rectum (STARR) is a relatively new surgical procedure used to treat chronic constipation and fecal incontinence due to rectal prolapse or rectocele. The procedure involves the removal of excess rectal tissue using a circular stapling device and is typically performed transanally. The STARR procedure has been shown to be effective in improving bowel function and quality of life, with a low risk of major complications. However, the success of the procedure appears to be dependent on several factors, including the severity of the prolapse or rectocele, the amount of tissue removed, and the experience of the surgeon. The procedure can be associated with a range of complications, including bleeding, infection, pain, rectal perforation, anal stenosis, fecal incontinence, urinary retention, and sexual dysfunction. The STARR procedure should only be performed by experienced surgeons in specialized centers, and patients should be carefully selected based on their individual characteristics and medical history. Further research is needed to determine the long-term outcomes and cost-effectiveness of the STARR procedure.
