The patient should be aware that sphincter repair or grafting may be required, and that in cases where fistulas are connected to other organs, in addition to repairing the pathway, an artificial anus may be required. Another aspect to be aware of before undergoing the operation is that during the procedure it is possible that certain findings may lead to modifications in the initial plan, which must be carried out in order for the treatment to be adequate.
There are currently no treatments that match the efficacy of surgery for anal fistulas, and specialists strongly recommend undergoing surgery once the diagnosis has been confirmed to prevent the fistula from persisting, acute inflammation, chronic suppuration and abscess formation.
Prior to surgery we recommend that you gather all the information regarding the procedure and the care requirements during the recovery process in order to be prepared and avoid surprises. It is important to keep in mind that like any surgery, an operation to treat an anal fistula involves certain risks even if performed correctly; these risks include bleeding and infection of the wound, inflammation, urinary retention, phlebitis and pain, which can be resolved with proper medical treatment, as well as possible complications of greater severity such as infection of the anus and perineum, anal stenosis, incontinence to gas and feces, and fistula reproduction.
What is assessed in an arteriovenous fistula?
The detection of changes in the characteristics of the pulse, murmur and AFV fremitus with respect to previous controls allows the diagnosis of stenosis, as well as determining its location.
What is a postoperative fistula and why does it occur?
Postoperative enterocutaneous fistulas are a severe, life-threatening condition, usually originating as a consequence of cancer treatment, inflammatory bowel disease or release of adhesions, although they can occur secondary to following a septic process …
What are postoperative fistulas?
Fistula is defined as an abnormal communication between two epithelialized surfaces. It is presented as a postoperative complication, with a high morbimortality. It is classified according to etiology, topology and physiology.
Thrill and fistula murmur
The patient considered the care lacking and untimely for the resolution of her problem, and observed a delay in the care, since she had to wait 4 months to be attended, which favored her affectation. Therefore, she denounced the facts as a crime of medical practice.
A median episiotomy was performed, without prolongation and without evidence of perineal tear. She went home the following day without any eventuality. On the seventh postpartum day, she went for evaluation because she presented fecal matter leaking from the vaginal introitus.
Initially, episiotomy was recommended as a way to facilitate the events of the second stage of labor, reduce trauma and maternal and neonatal morbidity associated with labor. Benefits described included: ease of repair compared to a spontaneous perineal laceration, decreased postpartum pain, and reduction of severe or 3rd or 4th degree lacerations.
The classification described by Sultan and accepted by the Royal College of Obstetricians and Gynaecologists (RCOG) classifies perineal tears into 4 grades, subdividing the 3rd grade into 3 subgroups (Table 1).
What specific laboratory study is performed in a patient with suspected AVF exit site infection?
If there is clinical suspicion of central venous stenosis, the imaging test of choice is fistulography or phlebography. If the patient already has an AVF, the study can be performed by direct puncture of the AVF vein (“outflow” segment).
What is dysfunctional FAV?
According to the five premises above, dysfunctional vascular access is defined as providing insufficient flow; causing ischemia in peripheral tissues; producing venous hypertension; failing to dilate the vein (this concept is new and is being used to denote a failure in venous …
Why does fistula occur?
A fistula is an abnormal connection between two parts of the body, such as an organ or blood vessel and another structure. Fistulas are usually the result of injury or surgery. Infections or inflammation can also cause a fistula to form.

Diverticular disease or diverticulosis is the most frequent benign pathology of the colon, usually a finding that is evidenced in screening videocolonoscopy nowadays, while in previous decades its finding was very frequent in contrasted colonic studies. The diverticulum (Refuge or perched on the side of the road) is an abnormal sac or pouch that protrudes from the wall of a hollow organ, in this case, the colon. A true diverticulum has all the layers of the intestinal wall, while a false diverticulum or pseudodiverticulum lacks part of the normal intestinal wall.
The most common diverticula in the human colon are protrusions of the mucosa through the muscular layers of the intestine. Since these mucosal herniations lack the normal muscle layers, they are pseudodiverticula. Diverticulosis or diverticular disease is the presence of diverticula in the colon.
What are the consequences of a fistula?
Fistulas can cause malnutrition and dehydration, depending on their location in the intestine. They can also cause infection and skin problems.
How dangerous is a fistula?
The risks and sequelae depend on the time of evolution of the disease and the complexity of the path of the fistula, whether or not it involves the muscles of the anus, which allow continence and evacuation at will. It requires medical attention as soon as possible and if the diagnosis is confirmed, it requires surgery.
How long can you stay with a fistula?
If a fistulotomy is performed, in one week you will be able to lead a normal life and the surgical wound will heal in 4-5 weeks. In the case of anal fistula intervention using the fistulectomy technique, recovery may take longer because the surgical wound is larger.
Venous hypertension arteriovenous fistula
Perianal involvement is one of the most aggressive and disabling forms of presentation of Crohn’s disease, occurring in 3.8 to 80% of patients,1-7 and this wide variation is due to the different inclusion criteria used and the follow-up time of the different series. When all perianal manifestations are included, their incidence rises as does that of series with longer follow-up. Its prevalence increases the more distal the luminal involvement is:
There are several classifications related to perianal disease, some of which only group the lesions together lacking value for the follow-up of the treatments performed, and others take into account the different manifestations and their clinical manifestations.
It has been described that surgery can be complicated by infection of the bed, non-healing wounds, strictures or lead to incontinence and proctectomy.14 The healing of fissures, as with the rest of the perianal manifestations, will depend on intestinal activity.
