AV or arterio-venous fistulas are unusual linkages between arteries and veins. In general, pure blood passes from the arteries to the capillaries to the veins and becomes devoid of nutrients and oxygen (becomes  impure ) by the time it reaches the veins. The capillaries in between absorb the nutrients, to supply them to the tissues and organs lying beneath them. In the case of AV fistulas, the capillaries are bypassed and blood passes directly between the arteries and the veins. Thus, organs are deprived of nutrients.

This can be a severe condition, leading even to heart failure.

AV fistulas and dialysis

Sometimes, AV fistulas have to be deliberately created on the body, to treat for severe kidney ailments requiring dialysis.

What is the surgical procedure for creation of AV fistulas for dialysis?

Following are the steps-

  A vascular specialist checks your arteries and veins to make sure they are sturdy enough to be able to support an AV fistula.
  Then, with the help of wave techniques or an angiogram, the depth of your blood vessels is recorded.
  Anaesthesia is then used on the spot, which is chosen for your AV fistula. Local anaesthesia (anaesthesia of only that spot) is preferred over central anaesthesia (anaesthesia of the whole body).
  With the help of a small cut on the skin surface, the surgeon accesses your blood vessels and makes a connection between arteries and veins.

After this process is completed, dialysis takes usually some weeks to begin.

Why should you go for AV fistula?

Following are the advantages-

  Foreign chemicals or devices, which may cause invasion and damage to vital internal organs, are not introduced in your body.
  As only local anaesthesia is administered, you have to spend significantly less recovery time or  downtime  after surgery.
  There is less chance of the wound becoming infected.
  There is a reduced danger of clotting.

AV fistulas are in essence an unusual connection between your arteries and veins, leading to undernourished organs due to capillaries being bypassed. In some cases like dialysis, AV fistulas need to be created and closely monitored. There are several advantages to this, but you will also need recovery time after the procedure is over.

AV Fistula - Its Surgery & Creation Of AV Fistula For Dialysis!

Anal fistula, a challenge for modern surgery, but can be cured with grade ksharsutra in Ayurveda (Indian system of medicine).  Anal fistula is a disease for which different methods of treatment have been advocated time to time, even today when we are talking about robotic surgery, this disease has no satisfactory method of treatment in modern surgery. The latest method of video assisted anal fistula treatment (VAAFT) is not satisfactory due to high incidences of recurrence after the surgery. But at Sushruta Anorectal Institute New Delhi; with the help of Graded KsharsutraTM all these patients of complex Anal fistula are being successfully treated.

In Ayurveda about 2000 yrs ago Acharya Sushruta has indicated ksharsutra treatment to treat fistula-in-ano. Late professor P J Deshpandey at the faculty of Ayurveda Institute of Medical Sciences B H U; had done extensive research in this field and established a treatment module to cure this disease. In 1990 Indian council of medical research has clinically evaluated this Ayurvedic treatment module at four premiere institutes in our country including AIIMS Delhi & PGI Chandigarh. Subsequently, it was concluded by I.C.M.R. that in the patients of fistula in ano, ksharsutra treatment is more effective& convenient as compared to modern surgery.

Ksharsutra is a thread coated with certain Ayurvedic medicines known for their antiseptic, debridement & healing properties. After u v sterilization this medicated thread (ksharsutra) is used under complete aseptic precautions in the patients. The patient is routinely investigated with special reference to any other associated disorder like hypertension, diabetes mellitus, tuberculosis etc. The next step lies in the proper identification& evaluation of the fistulous tract. It is mandatory to define the fistula tract wrt its depth, direction & branching pattern. This may be achieved by careful probing under expert hands using malleable probes& if required help may be taken from other investigations like x-ray fistulogram or MRI fistulogram. 

Once the tract has been clearly defined the Ksharsutra is placed in it with the help of certain instruments, under local anesthesia. This entire procedure is usually completed in ten to fifteen mins. As there is no cutting of tissues hence no bleeding, no pain & patients can go home after half an hr rest in the daycare room. The medicine-coated on the thread is gradually released in the tract. The cumulative effect of the coated drugs exerts a powerful debridement effect on the fistula tract & induces healing by the fresh & healthy granulation tissues. Thus Ksharsutra is the mechanism of drug delivery precisely at the tissues involved. 

Every seventh or tenth day the old sutra is replaced with a new Ksharsutra till there is a final cut through. It has been observed that the tract heals @ 0.5-1 cm per week. The post-operative complications like recurrence of the disease, fecal incontinence, bleeding is not seen with Ksharsutra treatment. Further, this therapy is performed as an OPD procedure. No general anesthesia & no hospitalization is required. Patient maintains his normal routine activities as usual during the treatment period. 

 At Sushruta Anorectal Institute; Rohini - New Delhi, we have been working on this disease including piles fissures & pilonidal sinus for the last 30 yrs. Here we have developed the concept of Graded KsharsutraTM which has given us a more effective & convenient way to treat anal fistula. At Sushruta Anorectai Institute we have treated on record thousands of patients of anal fistula from different states including overseas patients. We have records to prove that the patients of high anal complex fistula, those have been operated two or three times but failed to heal were successfully treated at this institute.

How to Treat Anal Fistula Naturally without Surgery

A fistula is an abnormal, tube-like connection, a passage or hole that forms between two organs or an organ in your body and your skin. There are various types of fistulas that can develop in different parts of your body but the most common types are-

1. Obstetric Fistulas: This is the name given to a hole between the vagina and rectum or bladder. A vaginal fistula that opens into the urinary tract is called a vesicovaginal fistula and one that opens into the rectum is called a rectovaginal fistula. 

A woman with obstructed labour or labour that is not attended by a doctor or a midwife, can suffer labour pain for up to six or seven days. And as the labour produces contractions that push the baby s head against the mother s pelvic, the soft tissues between the baby s head and the pelvic bone are compressed and do not receive adequate blood flow between the mother s bladder and vagina and/or between the rectum and vagina.
This means that a hole forms on the vaginal wall between the urinary tract and her rectum. The urine and faeces thus start to leak from the vaginal opening causing soiling and foul smell.

Apart from labour, hysterectomies that damage the vaginal wall can also cause such types of fistulas.

Enterovaginal   A woman may have gas and foul smelling fluids leaking out of her vagina due to an enterovaginal fistula which is a hole between the vagina and the digestive tract. It s usually caused due to inflammatory bowel disease or IBD and ulcerative colitis.

2. Anal fistula

These are fistulas that form between the end of the bowel and skin near the anus.

An anal fistula usually develops due to a previous or current anal abscess. An anal abscess is an infected cavity filled with pus found near the anus due to an acute infection in the internal glands of the anus.

Common symptoms are:

Pain in the anorectal area
Swelling
Redness
Fever
Rectal bleeding
Urinary symptoms, such as trouble initiating urination or painful urination
Causes:

Inflammatory bowel disease   a chronic condition of the GI track which causes inflammation
Diverticulitis   An infection in the large intestine
Tuberculosis, HIV
Surgery near the anus
Anal abscess and likewise anal fistula are treated by surgical drainage in which an incision is made in the skin near the anus to drain the infection causing an anal abscess. Hospitalization may be required for patients who have impaired immunity like diabetics.

Anal fistula though has no medical treatment and surgery is almost always necessary to cure it.

If the fistula is straightforward which means one that involves minimal sphincter muscle, a fistulotomy may be performed. This involves cutting open the whole length of the fistula so it heals.
Seton is another procedure in which a surgical thread called a seton is placed in the fistula and left there to help it heal.

Different Types of Fistula and Treatments!

Anal Fistula - What Causes It? 
An anal fistula refers to a small infected tunnel connecting the anus to the outer skin. Your body eliminates solid waste products or feces through the anus. When any of the glands inside the anus becomes infected or blocked, an abscess may form, which in turn results in formation of anal fistula. In about 50% of the cases, abscesses develop into fistulae. What are the causes for anal fistula? Anal fistulae occur primarily due to the formation of an abscess or infection in the anus. If the abscess does not heal completely after the pus has been drained away, a fistula can develop. 

Other factors responsible for the occurrence of anal fistulae are- 

Crohn s disease- a chronic condition where the digestive system becomes inflamed. 
Diverticulitis- an inflammation of the small pouches that develop along the intestinal walls. 
Hidradenitis suppurativa- a chronic painful skin condition which causes scarring and abscesses on the skin. Apart from these, people with HIV or infected with Tuberculosis disease also develop anal fistulae. If you ve had a surgery around the anus, then post-surgery complications may lead to infection or abscess on the skin. 
What are the symptoms to watch out for? 
The commonly observed signs and symptoms of anal fistulae include- 

Irritation or discomfort on the skin around the anus 
Occasional throbbing pain, especially while seated, moving around or having a bowel movement 
Nodular swelling around anal region 
Intermittent Discharge of blood or pus from an opening near anal orifice. 
How does Ayurveda treat anal fistulae? 
Ayurveda recommends Ksharsutra treatment for complete healing of Anal Fistula. 

In this procedure; Ksharsutra   a medicated thread is placed in Fistula tract. Medicine released from Ksharsutra debrides the fistula tract and induces healing. This medicine remains active for about 5-7 days so this thread needs to be changed with a new thread at weekly interval. No. of Ksharsutra changes required for complete healing of Fistula depends on length depth and branching pattern of fistula. It has been observed that Fistula heals at the rate of 0.5 to 1 cm per Ksharsutra changes so for a fistula tract of 3 cm length about 4-5 weekly thread changes are necessary for complete healing. Clinical trials conducted by Indian Council of Medical Research at AIIMS New Delhi have proved that Ksharsutra treatment is more convenient and more effective than Surgery in case of Anal Fistula. In this way Ksharsutra is the best way to treat Anal Fistula without Surgery.

Anal Fistula - What Causes It?

There are glands inside the anus that secrete fluids. Sometimes these glands can get clogged. Pus builds up in the blocked clogs, which get infected. This is called an abscess. Unless the abscess is treated right away, it will keep growing. It eventually punches a hole through the skin near your anus to drain the infected tissues and pus. This tunnel that leads from the gland to the hole is called a fistula.

Usually, it is an abscess that causes a fistula. But sometimes a fistula can be caused by tuberculosis, a bowel illness or sexually transmitted diseases.

What are the symptoms of anal fistula?

The symptoms of anal fistula are-

  Pain while sitting down
  Soreness around the anus
  Swelling and redness
  Bleeding
  Painful defecation
  Fever
  Foul secretion from a hole near your anus

How is fistula diagnosed?

If you complain of any of the above symptoms, a doctor will perform a physical examination on you.

Sometimes a physical examination does not reveal a fistula because the fistula can close for a while and then open up again. So then your doctor might ask you to get the following tests done-

  A blue dye test
  Computerized tomography (CT Scan)
  Anorectal ultrasound
  Colonoscopy.

Treatment for anal fistula

Unfortunately, there are no medicines that can treat fistula. If you are diagnosed with fistula, you will require surgery. However, it is a minimally invasive surgery with no risks involved.

The surgery is performed under general anaesthesia. A fistula surgery can be done in the following ways-

  If the fistula is located beneath the sphincter muscles, the surgeon cuts the fistula open so that it can heal and new healthy tissues can develop there.
  If the fistula passes through the upper part of the sphincter muscles, then the surgeon runs a special stitch through the fistula (seton stitch) so that the fistula can drain properly and heal. It takes 6 weeks for the pus to drain and the wound to heal
  Sometimes, a doctor will simply plug the fistula so it does not seep pus.

General and specific complications of a fistula surgery

Though it is a safe surgery, some complications may arise, but rarely. These may be general or specific.

General complications-

  Bleeding and pain
  Scarring around the region of the surgery

Specific complications-

  Pain while urinating
  The involuntary passing of wind or lose faeces

An anal fistula is a painful condition that refuses to go away and the only way to cure it is surgery.

Can Medication Treat Anal Fistula? Find Out!

Anal Fistula is a tunnel like communication structure between anal canal and outer skin. There are certain glands in anus whose secretions keep the anal passage lubricated. If due to any reason infectious agent invades these glands abscess formation occurs which subsequently spreads towards the skin and bursts outside forming an external opening.

So Anal Fistula presents itself as a nodular swelling in area surrounding anal opening. Intermittent pus discharge is seen from this swelling. When pus has accumulated there will be swelling and pain which subsides once the pus has been discharged and this cycle goes on.

Anal Fistula Treatment:

Anal Fistula cannot be treated by oral medicines only - Homeopathic/ Allopathic or Ayurvedic whatever it may be. Continuing oral medicines in hope for fistula treatment only worsens the problem. Different surgical options have been tried to treat Anal Fistula like Fistulectomy/ VAAFT/ Laser/ LIFT etc. but not satisfactory results have been found. A high incidence of recurrence around 20-25 % has been observed with these procedures. 

Besides this other complications like stool incontinence etc. are also seen if there is some damage to sphincter muscles. However Anal Fistula can be completely treated by Graded KsharsutraTM Treatment. Clinical trials conducted by Indian Council of Medical Research (ICMR) at AIIMS new Delhi; PGI Chandigarh and other premier institutes of medical sciences; have proved that Ksharsutra treatment is more convenient and more effective than Surgery in patients suffering from Anal Fistula.

In this treatment; first of all Fistula tract is defined with respect to depth, direction and branching pattern by careful manual probing and MRI Fistulogram. Once the Fistula tract has been defined properly; Graded KsharsutraTM - a specialized medicated thread is placed in Fistula tract. Medicine released from KsharsutraTM debrides the Fistula tract and induces healing. This medicine works for 5-7 days so old Ksharsutra needs to be replaced by a new thread at week or 10 days interval.

No. of Ksharsutra changes required for complete healing of Fistula depends on length of Fistulous tract. It has been observed that a Fistula tract of 3 cm length usually requires 4-5 Graded KsharsutraTM sittings at weekly intervals for complete healing. Thus with this recent concept of Graded Ksharsutra treatment of Anal Fistula has become more easy and more effective.
