Filter by:Anal fistulas are the main etiology of perianal abscesses and suppurations. They are common and generally associated with pain, anal incontinence, impaired quality of life and work incapacity. The therapeutic management of this disease has a double objective: heal the suppuration and preserve the sphincter function. Each year, anal fistulas affect 1 in 10 000 in the normal population, with a difference in prevalence between men and women (1.23 per 10 000 men and 0.56 per 10 000 women). The average age of the patients was 40 years (Simpson et al., 2012). In about 80% of cases, anal fistulas are secondary to an infection of Hermann and Desfosses' anal glands (cryptogenic or cryptoglandular). Infection of the anal gland can result in an abscess between the internal and external sphincters, which in turn can spread to other parts of the perianal region. The infection can follow many directions from this point in the intersphincteric plan. When the pus reaches the skin, the fistula is formed. Anal fistula therefore has always an intraductal origin, cryptic, with a primary port at this level, and the disregard of which causes the recurrence of the fistula; and usually a secondary port in the skin. Fistulas are usually divided into two groups. The first group contains fistulas called "simple", which are intersphincteric fistulas or trans-sphincteric involving only the lower third of the sphincter complex. Fistulas usually didn't affect any muscle. The second group contains fistulas called "complex". These are intersphincteric, trans-sphincteric, or even suprasphincteric, extrasphincteric fistulas. For many years, the treatment of choice was to open the fistula (fistulotomy), but this procedure was associated with a risk of incontinence, the consequences could be potentially devastating. Other surgical treatments include setons, fibrin glue, collagen plugs and advancement flap technique to cover internal opening of the fistula. The success of these therapies remains variable. The advancement flap technique remains a strategy of choice in the treatment of anal fistulas and particularly in the case of complex fistulas. The success rate of the advancement flap technique remains variable across studies but a recent meta-analysis finds a success rate of around 60%. A new technique for closing anal fistula is currently in development with the use of a closure clip nitinol (OTSC® Proctology Laboratory: OVESCO and French Distributor: Life Partners). This new technique has been validated in a porcine model of anal fistula, ensuring the safety of the device. A first case was published in a patient with complex anal fistula (high trans-sphincteric). After erosion fistula tract with a special brush, a nitinol clip (OTSC® Proctology) was deposited on the internal opening of the fistula. Eight months after surgery, the fistula was healed and the clip was removed by cutting with special pliers. This technique is currently being broadcast and dozens of patients were treated with this clip without any further scientific validation of the process. To date, this innovative technique of the closure clip has not yet been assessed in a randomized controlled trial. It is therefore essential to carry out a prospective evaluation in order to determine the effectiveness and safety of this new device in the case of complex anal fistulas.
Anal fistula is the most common Peri anal disease. It's a disease with an incidence of 9 in 100,000. Anal fistula is classified on the basis of its location into high and low anal fistula, above or below dentate line respectively. Multiple series have shown that the formation of a fistula tract following anorectal abscess occurs in 7-40% of cases. There are typically 8-10 anal crypt glands at the level of the dentate line in the anal canal arranged circumstantially. These glands afford a path for infecting organisms to reach the intramuscular spaces. The cryptoglandular hypothesis states that an infection begins in the anal canal glands and progresses into the muscular wall of the anal sphincters to cause an anorectal abscess. According to internal opening many author proposed certain classification but the standardized in all of them is Park's classification, so this study categorized the patient through this classification. There are four types of fistula-in-ano in Park's Classification intersphincteric (between internal and external sphincters is 70%), transsphincteric (across external sphincters is 25%), suprasphincteric (over sphincters), and extrasphincteric(above and through levator ani).High anal fistula is considered to be difficult to treat because of its location.This study diagnosed the internal opening of high perianal with the help of endoluminal ultrasound and MRI. Classic method of its treatment are fistulotomy, fistulectomy and Setone placement but these are associated with lots of complication like fecal incontinence,recurrence,pain.Therefore many method have been recently devised including Ligation of intersphincteric fistula tract (Lift), glue repair and flap advancement.Another recently introduced method for its treatment is Video-assisted anal fistula treatment (VAAFT) proposed by P. Meinero which has been associated with less complications.
Drainage of perianal abscesses is a well established treatment. Traditionally its been done in general anesthesia after the swelling has been localised its been drained with a knife. After surgical intervention complications can occur with recidivism, chronic fistulas that go from the anal to the skin and sometimes the anal sphincter is damaged which can cause problems with incontinence. Through ultrasound the abscess is opened under more controlled forms with a better visual overview. This is a new technique that has not been tested in larger studies. The aim with ultrasound-drainage as with traditional incision to drain the abscess so that the infected area can heal. The hypothesis is a reduction of recurrences and formation of fistulas with the use of 3D ultrasonography.
Perianal fistula is a chronic phase of anorectal infection that occurs predominantly in the third and fourth decade of life. According to Parks classification fistulas have been divided into intersphincteric, transsphincteric, suprasphincteric and extrasphincteric. Simple fistulotomy can be performed with satisfactory outcomes in low fistula tracts but in high (transsphincteric) fistulas it may affect anal continence seriously. Therefore sphincter preserving procedures should be preferred in these cases. Rectal advancement mucosal flap (RAF) is one of the methods used in surgical fistula eradication with high success rate in cryptoglandular fistulas. However, this technique is technically demanding and results can be expert depended with wide spread of healing rates (24-100%) in individual studies as referred in recent systematic review. Ligation of the intersphincteric fistula tract (LIFT) has been presented in 2007 as a simple sphincter preserving technique. The success rate varies between 40-95% with low overall incontinence rate (6%). The aim of the study is to compare the efficacy of the LIFT and RAF procedure for treatment of high perianal fistulas.
The anal fistula is a notorious disease due to its recurrence rate. Bhagandara is varyingly defined as a tear, ulcer or boil at Bhaga (Perianal region) within 2 finger circumference of it, causing painful abscess when opened is called Bhagandara. The Sanskrit word 'Bhagandara' has got two components-Bhaga and Darana. Bhaga means perianal region and Darana means to tear. The ancient Surgeon Sushruta has advocated various types of operations in Sushruta Samhita. He has advocated Kshara Sutra treatment due to probability of recurrence after surgery. Sushruta describes many kind of kshara like Palasa, Kadali. The most remarkable is Udumbara( Ficus Glomerata) among them. The present treatment modality Udumbara Kshara Sutra has been found effective due to its action of proper drainage of pus from the fistula that leads to a proper healing and as adjuvant therapy by avoid recurrence in Fistula in ano. Hypothesis; Present treatment modality Udumber Sutra will found to be useful in tne management of Fistula in ano.
The purpose of this study is to determine whether anal fistula plug or endorectal advancement flap is more successful in the treatment of anal fistulas and compared both procedures with regards to cost.
Effectiveness of silver nitrate solution in treatment of anal fistula is is aimed to be investigated.
The aim of this study is to compare short term (3 week) with long term (6 months) treatment with seton prior to LIFT surgery. The main end-points are recurrence rates and complication rates after surgery.
Background: Fistula in ano is one of the most common diseases of the ano rectal region. Treatment of Fistula in ano has puzzled the medical fraternity due to its complex nature. Commonly prevalent surgical treatment for anal Fistula, that is "Fistulectomy" does not provide successful cure for the disease, post operative complications and recurrences being common. Acharya Sushruta an ancient Indian Surgeon has described in his text ' Sushruta Samhita' about an ancient Ayurvedic technique of medicated thread called Ksharsutra treatment for Bhagandara ( Fistula in ano). Treatment of anal Fistula (Bhagandara)and Nadi-Vrana(Sinus) with Ksharsutra was practiced by Sushruta (1000-600B.C.) . Hypothesis: Aycharya Sushruta advocated Kshar Sutra therapy in Fistula in ano and in various types of Fistula.
The aim of this study is to evaluate the effect of hyperbaric oxygen therapy (HBOT) on patient suffering from residual Crohn's disease related perianal fistulas already treated with TNF alpha blockers
