patient's quality of life and functional changes after fistula surgery

Conditions: Anal Fistula

Summary: this is a prospective observational study that will monitor the effects of surgery for anal fistula on the patient quality of life using many valid questionnaires

anal fistulas can be classified as simple or complex. simple anal fistula includes low trans-sphincteric and intersphincteric fistulas that cross less than 30% of the external sphincter fibers. on the other hand, complex anal fistulas comprise, high trans-sphincteric fistulas, suprasphincteric, extrasphincteric fistulas patients with anal fistula often complain of recurrent perianal discharge and pruritus ani. sometimes recurrent abscesses develop due occlusion of the external opening leading to episodes of fever and exquisite perianal pain. diagnostic modalities that aid in the diagnosis of anal fistula include fistulography, endorectal ultrasonography, mr fistulography while the treatment of simple anal fistula is usually straightforward with fistulotomy being recommended as the first line of treatment ; the management of more complex cases requires more sophisticated treatments aiming to preserve the anal sphincters and to eradicate the fistulous track. surgery for complex anal fistula includes the placement of seton, anal advancement flap, laser ablation, fistula plug, and video-assisted anal fistula treatment. there exists a debate about the optimal management of low anal fistula with both fistulectomy and fistulotomy considered as viable options for treatment. fistulectomy involves complete excision of the fistulous tract, eliminating the risk of missing secondary tracts and providing complete tissue for histopathological examination. on the other hand, fistulotomy involves lay open of the fistulous tract, thus leaving smaller unepithelized wounds, which hastens the wound healing . a recent meta-analysis found no significant difference between both procedures regarding recurrence of anal fistula, yet with accelerated healing time in favor of fistulotomy .recently, alternative therapies have been employed in the management of cryptogenic anal fistula in an attempt to render the surgery more minimally invasive and to reduce the likelihood of post-operative fecal incontinence . these treatments have included ligation of the intersphincteric fistula tract (the lift procedure) either with or without the deployment of a biosynthetic mesh , or fistula clip closure techniques , and a range of endo-fistula therapies including video-assisted anal fistula treatment (vaaft) , anal fistula plugs , and a variety of injected biomaterials , the ''fistula laser closing'' (filactm) device (biolitec, germany) is another endo-fistula management technique . there is few studies assessing the changes in quality of life that occurs after fistula surgery whatever its technique and the aim of this study is t assess the impact of intervention for fistula on patient's quality of life
