Fistula In Ano an Ayurvedic Overview(Kshar Sutra) Ancient but More Effective then any other Modern Process

Fistula in ano is the most frustrating problem for anyone , it makes person suffer more then any other disease , person who has fistula in ano is unable to live his normal life, unable to do normal things and most of all it may change to Carcinoma cancer due to chronic inflammation and irritation to the tissue ,

there are many options for the treatment of fistula but most of them has high recurrence rate, so the use is limited only only the ancient ayurvedic Kshar Sutra has max 99% success rate in fistula in ano with nil recurrence rate as compared to other process and it’s very cost effective and other best thing about it no long and bad scars as compared to other processes.

IntroductionAbout Kshar Sutra

• This disease, high anal fistula, a common ano-rectal disorder which usually results as a sequel to some varieties of ano-rectal abscesses, is as old as mankind and a challenge to surgeons even today. Fistula-in-ano has been recognised as a distinct entity for thousands of years. In the fifth century B.C., Hippocrates advocated the laying open of fistulas, including complex fistulas. One would think that after 2,500 years the controversies in the management of fistula-in-ano would have been resolved. But this is not the case and much about the management of fistula-in-ano is still being debated. Available surgical procedures may not only result in incontinence but also recurrences. They cause discomfort and absence from work with the consequent economic strain.
• If the theory that both the abscess and the fistula-in-ano have a common cause is accepted, the two conditions can be considered simultaneously. Indeed, the term “fistulous abscess” has been used to describe this problem. The abscess is an acute manifestation, and the fistula is a chronic condition. A fistula is an abnormal communication between any two epithelial-lined surfaces. A fistula-in-ano is an abnormal communication between the anal canal and the perineal skin. Many of these fistulas are easily recognized and readily treated, but others can be very complex and correspondingly difficult to manage.

• Keeping these problems in mind, Susturta (800 B.C) has described the kṣhrasūtra technique whereby a medicated alkaline thread, impregnated with the paste of Curcuma longa and latex of Euphorbia rerifolia, is employed along the fistula track which cuts itself and heals the wound naturally from inside (1). However, here are a few questions which need to be addressed to make this technique relevant in the present scenario:
• • Where and when should an abscess be drained? Can kṣārasūtra be appliedimmediately after drainage?
  • Should a primary fistulotomy be performed before the kṣārasūtra application?
  • What pre-operative evaluation is essential for preventing recurrences and other complications?
  • Should a simple fistula be managed by fistulectomy or fistulotomy?
  • Does kṣārasūtra also prove to be the best technique for the management of complex fistulae? :: yes it is.

Where and when should an abscess be drained? Can kṣarasutra be applied immediately after drainage?

• The crypto glandular nature of fistula-in-ano is now generally accepted. Eisenhammer coined the term ‘fistulous abscess’ to denote the continuum between the stage of acute abscess and chronic fistula-in-ano. An abscess can be classified as peri-anal, intra-muscular, ischio-rectal or supra-levetor. With the exception of supra-levetor and some intra-muscular abscesses, most can be managed in the clinic under local anesthesia. A cruciate incision is made as close to the anal canal as possible without damaging the external anal sphincter. The skin edges are trimmed to promote adequate drainage, and haemostasis is achieved using electrocautery. There is no need to aggressively break the loculations as they spontaneously rupture and drain into the cavity. Antibiotics may not be necessary until and unless there is a massive peri-anal abscess. Those in favour of primary fistulotomy argue that it eradicates the infection process, thereby eliminating or reducing the incidence of recurrent abscess or fistula formation. Those against primary fistulotomy point to the difficulty in identifying the fistula tract and primary opening in the setting in of acute inflammation. Overzealous probing may result in the formation of a false tract, which makes it difficult to manage supra or extrasphincteric fistula (2). In addition, proponents of delayed fistulotomy argue that acute ano-rectal suppuration will not inevitably lead to the formation of fistula-in -ano.
• kṣārasūtra application at this stage, without finding the exact internal opening, is a futile exercise. But recurrent drainage will probably have internal openings: in such conditions kṣārasūtra application may be useful and successful.

 Should a primary fistulotomy be performed before kṣārasūtra application?

• Controversy exists as to whether an immediate fistulotomy be performed before kṣārasūtra application. Those in favour of primary fistulotomy argue that it eradicates the infectious process, thereby eliminating or reducing the incidence of recurrence. Moreover it drains all the infectious material very fast, thus minimising post-operative pain (3).
• Nearly 60 percent of those patients treated with partial fistulotomy with kṣārasūtra application were spared repeated fistulotomy (4). Disturbances in continence were found in some cases apart from heavy bleeding and a big wound. Higher antibiotics are essential in the post-operative period. Primary fistulotomy, except in rare instances, should be discouraged.

What pre-operative evaluation is essential for preventing recurrences and other complications?

• A careful history and physical examination are crucial in the evaluation of the patient with a chronic fistula-in-ano. A focused history regarding gastrointestinal symptoms, diarrhoea, previous ano-rectal surgery, and prior history of any ano-rectal abscess is taken. Careful examination for stigmata of peri-anal Crohn’s disease should be done, including lateral fissures, hypertrophied skin tags, and anal stenosis. Sigmoidoscopy is routinely performed at the time of fistulotomy, but in the absence of significant history or physical findings, it is not necessary to aggressively rule out Crohn’s disease (5).
• Tools currently available include fistulography, sonography, magnetic resonance imaging and manometers. All biophysical evaluations have their role in assessing the internal sphincter from the anal mucus and ultrasonography in the evaluation of the pathology in the ischio-rectal fossa and in the evaluation of supra-anal infra-levator extensions. However, these procedures have the disadvantage of being expensive and are not uniformly available (6).
• The goals of surgery for fistula-in-ano are the eradication of infection and prevention of recurrence while minimising disturbances of fecal continence. A retrospective study of 975 high anal fistula cases with kṣārasūtra application to study the associated factors revealed that the majority had true high anal fistulae, horse-shaped extension and some even did not have an internal opening. Previous fistula surgery was also a factor associated with recurrences.

Does kṣārasūtra also prove to be the best technique for the management of complex fistulae?

• Several techniques are available to treat a patient with a fistula. However, modern surgical procedures like fistulotomy or fistulector my not only result in recurrence but also cause a number of complications like stenosis, retention of urine, sphincteric incontinence. Discomfort, surgery induced weakness and economic strain are additional disadvantages. These surgical processes require patients to undergo painful operative and post-operative procedures and can also result in incontinence. Treatment should always be a balance between curing the inflammatory process and preservation of the sphincter function. (7)
• More complex fistulas like high anal fistula, horseshoe extension or fistulas in high-risk situations, especially in female patients with anterior fistulas, require investigation before treatment in order to decrease complications of incontinence or non-healing. We have not found fistulography to be helpful for these fistulas. However, ultrasound and MRI can certainly provide important information about anatomy and identify multiple tracts and occult small abscesses. These tests are particularly important in the recurrence of poorly draining fistula or in situations where the patient has symptoms of pain and intermittent drainage although no fistula tract can be identified (8).
• Keeping all these problems in mind, there is a new approach of kṣārasūtra which is employed after probing the track with a malleable probe and holding the thread in the sphincter bundle. Because of its kṣaṇana (burning) and kṣaraṇa (cutting) properties, the thread cuts the track from inside gradually and allows for simultaneous healing. In this, the cutting property may be attributed to the alkaline nature of the thread and the healing property may be attributed to the turmeric powder and the latex of Euphorbia nerifolia (9).
• This less extensive surgical procedure does not disturb the sphincter bundle, thus safeguarding the sphincter tone and preventing post-operative incontinence. The kṣārasūtra holds the major track and allows the other minor track to drain and heal spon-taneously given sufficient time and scope. This can destroy the cryptic material of the track and prevent recurrence. It does a chemical fistulectomy and averts incontinence. The efficacy of the treatment is measured with UCT (unit cutting time). The correlation between the length of the track and duration of treatment is statistically significant (10).

Conclusion on Kshar Sutra

• Anal disease, although a common cause of morbidity in the general population, is often poorly understood and managed by medical students, general practitioners and surgical trainees. Surgical residents frequently fail to grasp the finer details required by anal surgery, considering it not particularly exciting compared to other more prominent procedures. Acute ano-rectal abscess and fistula-in-ano are usually quite simple to manage. Most acute abscesses can be dealt with in a clinic under local anesthesia without major trouble to the patient. Those patients who develop a chronic fistula-in-ano can usually be managed by simple fist-ulotomy methods. An array of surgical techniques is available to the surgeon treating a patient with high anal-fistula, but, in conclusion, kṣārasūtra undoubtedly proves to be a superior and more successful procedure with a 98 percent success rate some says 99.96% success rate.
