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!

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?

Anal Fissure is a small tear in the anal area. This can happen due to injury while passing hard formed stool or even by repeated bowel motion. It may be very painful especially at the time of passing hard stool. 

Symptoms

Most commonly sought symptoms in Anal Fissure are as given below: 

  A noticeable tear in the skin close to the anus. 

  Cutting or burning pain in anal passage while passing stool which may persist for a considerable time

  Sometimes pain is so severe that patient stops eating in an attempt to avoid defecation to avoid pain

  Blood stains on stools may also be there

  If not treated in time; skin starts growing from the lower end of fissure to form a tag known as sentinel tag/sentinel piles.

  At times; sentinel tag may get inflamed.

Causes

  Passage of hard stool through anus. 

  Chronic Diarrhoea

  Trauma to the anus and anal canal like during childbirth

  Inflammation in anus because of crohn's disease or some other inflammatory disease 

Anal Fissure treatment: Diet: High fiber diet like green leafy vegetables, salads, fruits like papaya, chikku are advised. Resins with milk can also be taken in night. Adequate quantity of liquids especially butter milk is advised. Banana, apple etc. should be avoided. 

Graded Kshar Karma & Ksharsutra: Anal Fissure can be completely treated by Graded Kshar Karma and Ksharsutra treatment. In acute anal fissure; stool softener along with Graded Kshar Karma is advised. In this treatment; Graded Kshar - a specialized Ayurvedic medicine is applied in fissure region. This medicine debrides the fissure and induces healing. Usually pain subsides in a week or 10 days time period when fissure is still in healing phase.

Considering pain has subsided; some patients discontinue the treatment to further aggravate and complicate the problem. For complete healing of anal fissure usually 3-5 Graded Kshar Karma sittings are required at a weekly interval. In between these weekly sittings patients are advised to apply certain medicines in anal passage by themselves. If anal fissure has progressed to development of sentinel tag then Graded Ksharsutra TM treatment is the treatment of choice. 

In this treatment Graded Ksharsutra TM is ligated at the root of sentinel tag. Medicine released from Ksharsutra blocks the blood supply of sentinel tag and it sheds off in a week or 10 days time period. No hospitalization or bed rest is required in this treatment. Patient can continue his normal routine activities as usual during his treatment. So, you can say no to surgery in Anal fissure.

Anal Fissure - Say No To Surgery!

An anal fistula, is also called as fistula- in -ano, it is a small channel that develops between the end of the large intestine called the anal canal and the skin near the anus. This is a painful condition, especially when the patient is passing stools. It can also cause bleeding and discharge during defecation.

Genesis of fistula-in-ano
Almost all anal fistulae occur due to an anorectal abscess that begins as an infection in one of the anal glands. This infection spreads down to the skin around the anus causing fistula-in -ano. The anorectal abscess usually leads to pain and swelling around the anus, along with fever. Treatment for anorectal abscess involves incising the skin over the abscess to drain the pus. This is done usually under local anesthesia. A fistula-in-ano happens when there is failure of the anorectal abscess wound to heal completely. Almost 50% of patients with an abscess go on to develop a chronic fistula-in-ano.

Symptoms

Pain- Constant pain which gets worse when sitting down
Irritation around the anus, like swelling, redness and tenderness
Discharge of blood or pus
Constipation or pain while evacuation
Fever
Diagnosis
A clinical evaluation, including a digital rectal examination under anesthesia, is carried out to diagnose anal fistula. However, few patients may be advised screening for rectal cancer, sexually transmitted diseases and diverticular disease.

Treatment
The only cure for an anal fistula is surgery. The type of surgery will depend on the position of the anal fistula. Most patients are treated by simply laying open the fistula tract to flush out pus, called Fistulotomy. This type is used in 85-95% of cases and the fistula tract heals after one to two months.

Seton techniques: A seton is a piece of thread (silk, plastic) which is left in the fistula tract to treat anal fissures. This is used if a patient is at high risk of developing incontinence after fistulotomy.
Advancement flap procedures: When the fistula is considered complex, carrying a high risk of incontinence, then this advanced technique is used.
Other techniques like Fibrin glue and Bioprosthetic plug are also used to surgically treat anal fistulas. In the Fibrin glue technique, glue is injected into the fistula to seal the tract, after which the opening is stitch closed. Bioprosthetic plug is a cone shaped plug made from human tissue, which is used to block the internal opening of the fistula. After this stitches are used to keep the plug in place. 

Whatever the surgical technique, one can experience minor changes in continence. Patients usually don t require antibiotics after surgery but have to take pain medication. They may also have to use gauze to soak up drainage from anus. After surgery, patients should seek help if they have increased pain or swelling, heavy bleeding, difficulty in urination, high temperature, nausea or constipation.

Fistula-in-Ano or Anal Fistula - How It Can Be Treated?

Is It Fissure Or Fistula? Don't Get Confused!

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.
