What is Fistula

The Most Advanced State Of Art Daycare Surgery Centre In Delhi/NCR.

An anal fistula commonly known as fistula in ano is a narrow tunnel with its internal opening in the anal canal and its external opening in the skin near the anus. They're usually the result of an infection near the anus causing a collection of pus (abscess) in the nearby tissue. When the pus drains away, it can leave a channel behind. The biggest challenge is to prevent recurrence of fistula.

The risk factors for recurrence can be broadly classified into four categories: 1) The fundamental anatomy of the fistula and presence of comorbid diseases like Tuberculosis, Diabetes, Chronic Disease, Malignancy 2) lack of proper preoperative assessment of the fistula, which includes failure to recognize the internal opening and overall structure of the fistula, 3) intraoperative loopholes that include improper procedure selection, inexperience of the surgeon, and failure to get rid of the entire tract along with its ramifications, and 4) lack of proper postoperative care in the early and late periods following the surgery. Fistulas are classified by their relationship to parts of the anal sphincter complex ( that allow us to control our stool). They are classified as intersphincteric, transsphincteric, suprasphincteric and extrasphincteric.  The intersphincteric is the most common and the extrasphincteric is the least common. These classifications are important in helping the surgeon make treatment decisions.

Cause Fistula

The Most Advanced State Of Art Daycare Surgery Centre In Delhi/NCR.

More than 90% anal fistulae are a result of an anorectal abscess. An anorectal abscess begins with infection in one of the anal glands. The infection may stay in the space between the sphincters (the intersphincteric space), may spread down to the perianal skin, or may extend through the external anal sphincter.

With a previous history of perianal abscess or any surgical intervention in past, patients having fistula in ano presents with complaints of persistent discharge of pus through an external opening in perianal skin. The other characteristic part of patients complaints include sudden appearance of pain and swelling in the previously dormant perianal region, followed by discharge of pus and relief of pain. Associated fever can also be a feature.

Risk Fistula

  • Infection

    Fistulas can cause a lot of discomfort, and if left untreated, may cause serious bacterial infection, which may result in sepsis, a dangerous condition that can lead to low blood pressure, organ damage or even death.

  • Incontinence

    In rare cases, surgery can damage the anal sphincter muscles (the ring of muscles that open and close the anus). If the muscles are damaged, you may lose some control of your stool, leading to faeces leaking from your rectum (the area where they are stored). This is known as faecal or bowel incontinence.

  • Recurrence of the anal fistula

    In some cases, the fistula can recur despite surgery. After having a fistulotomy, the recurrence rate can vary depending on factors such as whether it is simple or complex.

A comprehensive rectal examination will be performed by an expert proctologist in our fistula laser hospital. Our doctors usually diagnose an anal fistula by examining the area around the anus. He or she will look for an opening (the fistula tract) on the skin, then try to determine how deep the tract is, and the direction in which it is going.

Tests for identifying fistulas
1.    Contrast tests. A vaginogram or a barium enema can help identify a fistula located in the upper rectum.
2.    Blue dye test.
3.    Computerized tomography (CT) scan.
4.    Magnetic resonance imaging (MRI).
5.    Anorectal ultrasound.

Surgery is usually necessary to treat an anal fistula as they usually do not heal by themselves.

There are several different procedures. In fact, the surgical procedure chosen by a proctologist will depend on the position of fistula and whether it's a single channel or branches off in different directions. Fistula treatment has been revolutionised over the years by arrival of new age ambulatory surgery or Day Care surgery is a clinical admission for a surgical procedure, with discharge of the patient on the same working day. We have a trained anesthesiologist, OT assistant, and nursing assistant to perform to do the advanced procedures like LASER and LIFT. Dr. Sandip Banerjee is one of the leading Colorectal surgeon practises in all above methods of treatment. But the decision of the modality depends on type of fistula.

Doctor feel anything abnormal sigmoidoscopy test, in this test doctor inserts small fiber-optic camera into your rectum. E

The common minimal invasive surgical procedures are:
The most common type of surgery for anal fistulas is a fistulotomy. This involves cutting along the whole length of the fistula to open it up so it heals as a flat scar. A fistulotomy is the most effective treatment for many anal fistulas, although it's usually only suitable for fistulas that do not pass through much of the sphincter muscles, as the risk of incontinence is lowest in these cases.

LIFT procedure
The ligation of the intersphincteric fistula tract (LIFT) procedure is a treatment for fistulas that pass through the anal sphincter muscles, where a fistulotomy would be too risky.
During the treatment, a cut is made in the skin above the fistula and the sphincter muscles are moved apart. The fistula is then sealed at both ends and cut open so it lies flat. This procedure has had some promising results so far

Laser surgery
Radially emitting laser fibre treatment involves using a small laser beam to seal the fistula. Laser closure is a safe and effective treatment for transphinteric anal fistula. FiLaC Fistula-tract Laser Closure, which means the closure of the anal fistula due to the use of a laser procedure involves completely removing the entire length of the fistula tract and closing the internal opening of the fistula using a laser diode source and a radial laser probe. The laser FiLaC procedure for anal fistula therapy is an advanced, safe, effective, minimally invasive, sphincter-preserving procedure with a high success rate.

Our patients and our surgeon will decide on the best anesthesia to use during the surgery. Choices include:
•    general anesthesia, which puts patients into a deep sleep throughout the surgery
•    Saddle block is a low dose of spinal anesthesia which involves medication that numbs your body from the waist down being delivered by a shot into your back
•    local anesthesia, which numbs only your anus and rectum

Patient can expect rectal and anal pain after having surgery. So doctor will prescribe a painkiller to ease the discomfort. Most patients will need a dressing over the surgical incision following the surgical procedure while the wound heals. The dressing needs to be changed regularly, so it is important that they understand how they can do this themselves at home.The following tips may help keep the area around the fistula clean and prevent infection or irritation: 

1) Put a gauze pad over the opening of the fistula to absorb the drainage. This is normal in the days after surgery if needed. 

2) Use warm water and cotton wool to wash the skin, rather than a towel or sponge – pat the skin dry rather than rubbing it, or use a hairdryer on a low setting.

3) Sitz baths may help relieve discomfort and promote healing. A sitz bath is soaking the anal area in plain warm — not hot — water for 15-20 minutes several times a day. ... This helps the area to heal and rarely interferes with the control of bowel movements. Complete healing takes place in a few weeks.

4) Avoid any activities that involve heavy lifting or pulling and long sitting

5) Fiber and laxatives are useful to assist in regular emptying of the bowel and prevent constipation, which can put stress on the operated area.
