Vaginal Rectocele Repair|
Rectocele repair is typically done to correct bulging of the bottom wall of the vagina. This bulging can cause sympt oms such as the sensation of sitting on a ball, incomplete emptying of the rectum, and pelvic discomfort. The surgery is usually done through a vaginal approach, but in some circumstances a combined abdominal and vaginal approach to the repair is made. Surgery typically starts by making and incision along the vaginal skin overlying the rectum. The tissue over the rectum is assessed for areas of weakness or broken fascia tissue. These breaks and weaknesses are repaired with suture and sometimes covered with a graft or mesh. If there is any bulging of the bladder, this will also be repaired at the same time- this is called and anterior repair or cystocele repair. The most common postoperative symptom after rectocele repair is rectal pressure and discomfort. This should resolve over several weeks as the tissue heals. The success for this procedure to correct the bulge is over 80-90% depending on the technique used. Symptoms improve or resolve between 60-80% of the time. Light vaginal bleeding can occur as the incision heals and some discomfort with bowel movements is normal, initially.
The risks of the procedure are those general risks of any major pelvic surgery, which include the risk of an anesthetic, the risk of blood clots, and infection and bleeding. With any surgery there is always the risk of dying, although this is very rare with benign (non-cancer) gynecologic surgery. Other possible complications are injury to the bladder, urethra, bowel, ureters, blood vessels and nerves. Injury to the bowel, primarily the rectum, can occur during these surgeries, but fortunately is rare. Patients with any previous surgeries may be at greater risk of bowel or rectal injury. Nerve injury is rare, but may result from longs surgeries, and usually resolves with time.
It is possible that a graft or mesh may be used during the surgery to help in the long term success of the repair. The possible types of grafts/meshes we use include cadaveric fascia (Tutoplast), cadaveric dermis (Repliform), or prolene (Gynemesh). With any type of graft of mesh there is the possibility of rejection or exposure of the graft/mesh, such that the vaginal incision opens up partly. The more common exposure may be able to be treated with observation or a minor procedure in the office. Extremely rarely, this mesh/graft could erode into the rectum or bladder requiring more extensive surgery.
Other risks, common to all pelvic surgery, include the possibility of clot formation in the legs or lungs. This can be a life threatening condition. Anesthetic risk includes collapse of a portion of the lung, pneumonia, and very rarely, death. Prevention of these complications includes use of compression stockings during surgery, early walking after the operation, deep breathing exercises and coughing, and use of an incentive spirometer. Pre-operative medical conditions such as diabetes, high blood pressure, lung disease, and heart disease increase the risk associated with surgery, as does advanced age. Obesity is an additional risk factor, and along with diabetes can affect the healing of the incision. Smoking can also affect healing.
Possible long term complications from rectocele repair include narrowing or shortening of the vagina due to the healing process. This could cause difficulty or pain with intercourse and may require dilation or a minor surgery to correct the narrowing. It is of critical importance that you do not do any heavy lifting (over 5-10 pounds) after surgery, as the success of the procedure relies on good scarring around the repair site. Also, we recommend no intercourse, douching or tampons for the first 4-6 weeks. You will go home with pain medicine and a stool softener, as excess straining can affect the repair. Sometimes we recommend you do sitz baths at home to aid in the healing of the outside vaginal tissues. Please call us if you have a fever over 100.5 F consistently at home, pain that worsens or is not controlled by medicines, excess discharge or concerns for wound infection, heavy vaginal bleeding or discharge, nausea or vomiting, leg pain or swelling, or new shortness of breath.
