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!

Fissure in Ano, also known as Anal Fissure, is basically a small longitudinal cut in skin that lines the opening of the anus. Fissures cause bleeding and severe pain in the bowel movements. These are very common in the general public, but often confused with other pain. A fissure can happen at any point in your lifetime and can have equal general distribution.

Types of Fissure in Ano:

  Acute Fissure: Fissure in Ano less than 6 weeks of duration is known as Acute Fissure.

  Chronic Fissure: Anal Fissure with more than 6 weeks of duration is known as Chronic Fissure. 

Causes of Fissures in Ano:

  Anal fissures are basically caused by stretching of the anal muscles beyond its capability.

  In adults, it is caused by the passing of large stools, constipation or by prolonged diarrhea.   In older adults it is caused by the less flow of blood to that area.

  It is also caused by sexually transmitted infections (syphilis, chlamydia, herpes) and it results in fissures.

  Anal sex can also be the cause of fissures.

Symptoms of Fissures in Ano:

  Tear in the skin around the anus

  Small lump of skin, or skin tag next to the tear

  Pain during bowel movement

  Stools with blood or pus

  Itching and burning in the anal area 

Preventions During Fissures in Ano:

  One should drink enough water.

  One should have high fibre diet so that one does not suffer from constipation.

  Be careful and hygienic after anal defecation.

  In case of suspected fissure or any kind of pain, use a lubricating ointment.

  Sit in lukewarm water

Treatment for Fissures in Ano

Surgical treatments are not recommended, but there are some other measures that can be taken and are listed as follows:

  Some prescribed medication to lower the severity of pain.

  Nitroglycerin ointment may help heal the fissure.

  Having a rich fiber diet as a lifestyle change.

  Drink enough water as that helps in softening the stool.

  Sometimes Stool softeners may be required to soften the bowel movement.

When Anal Fissure does not heal with all of the above listed things, then a surgery may be required:

  Lower most part of the internal anal sphincter is divided laterally. With this acute fissure heals of its own. In chronic cases one may require to undergo fissurectomy.

  The surgery decreases the anal pain and spasm, allowing the fissure to heal.

  If a sentinel pile is present, it is removed to heal the fissure. 

It is important to note that any kind of treatment requires 6-10 weeks to recover. However, the pain may disappear just after 2-4 days after the surgery. One must consult a doctor before going for any treatment. This surgery can also be performed with LASER,where there is less trauma and early recovery is posssible.

Fissure In Ano

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!

If you think fissure and fistula are the same, you are mistaken. While the term fissure refers to the tear of the skin, fistula refers to the abnormal tube-like passages or connections between organs. Fissures get cured with or without treatment in a few days to few weeks, and do not lead to complications. On the contrary, fistulas when left untreated may lead to complications.

So, read on further to know about the distinction, how to recognize the symptoms and avail treatment.

What is anal fissure?
An anal fissure can occur due to various reason, such as prolonged diarrhea, anal sex, vaginal childbirth, rectum cancer, etc. For majority of the cases, it is usually due to constant constipation or strained bowel movements, that tear down the muscles controlling the sphincters to the inner rectum or the anal canal.

What is anal fistula?
Anal fistulas are not tears but abnormal abscesses near the anus, filled with pus. In fistula, a tunnel is formed under the skin which connects these abscesses to the infected glands. Fistulas are usually the results of present or previous abscesses. If ignored or left untreated, one single fistula can lead to the development of a more complex fistula, where the single fistula tract ends up creating multiple openings.

Symptoms of anal fissure and anal fistula
Some of the common symptoms of an anal fissure are excruciating pain in the anal area every time the bowel movement occurs, constant itching or burning sensation in and around the anus, bloody stool and visible tears and cracks around the anus.

For anal fistula, some of the very common symptoms are a throbbing pain in the anus, which continues to increase, difficulty in sitting down for longer period, swelling and redness around the anus, accompanied by skin irritation, discharge of blood and pus, and at times fever.

Treatment options
To completely cure anal fissure and fistula, it is the various surgical options that are the most effective ones. However, when diagnosed in its earliest form, medications like antibiotics, analgesics, and antipyretics can often help. It is solely depending on the location, type, and size or severity of the fistula or fissure, the treatments may vary from person to person and so does the recovery time.

Though, these conditions cannot be cured with dietary changes or exercise, following a healthy diet can boost healthy bowel movement, reducing chances of constipation or diarrhea that results in fissures.
Prevention is always better than cure. Therefore, it is essential that you visit the nearest medical facilities once you notice any signs of fissure or fistula , to avail the right treatment and get relief from the symptoms quickly.


Don't Confuse Fissure With Fistula!

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!

An abnormal junction or connection between two organs or tissues is referred to as a  fistula . It targets two hollow organs, vessels, or tissue structures. It occurs mostly in the rectum, vagina, however can affect the intestines and the eyes too. It results in extreme pain, discomfort and should be treated as immediately as possible to prevent infection.

It can induce sensations of:

Extreme irritation or itching
Discharge with unusual odor (if the fistula is located near the anus/vagina)
Irritable bowel syndrome
Excess pus
High body temperature
Blood discharge
Diagnosis
In case or prolonged tension and pain in these areas, a proctoscopy should be conducted for diagnosis. It most commonly occurs in women who have sustained prolonged labor (over 2-3 days). However, other causes include:

Digestive malfunction
Abscesses(formation of pus in hollow organs)
An unhealthy lifestyle which includes excessive indulgence in alcohol and tobacco

Ayurvedic treatment for fistulas are available which aim to sooth the inflammation by slowly remedying the wound through natural and safe measures. Since Ayurvedic practices are non-toxic, non invasive and completely safe, one can avoid the drastic measures that surgery consists of, and also avoid the side effects of medicines.

Ayurvedic remedies of fistulas include
Ayurvedic doctors have developed several oils, ointments and medications that are readily available in the market. The medications usually consist of a mixture of herbs, roots and plants that aim to restore the physical systems and also soothe the affected area.

The importance of buttermilk added with rock salt and black pepper also allows the enzymes of our body to multiply and thereby cure the fistulas internally.
Radish juice with a pinch of cumin is also recommended to be consumed after meals to improve digestion and empower the immune system.
A healthy lifestyle and fitness routine consisting of yoga and exercises also contribute to improve conditions in the patient by facilitating blood circulation and metabolism.
