Plastic and reconstructive surgeries of the anal canal
Anal canal plasty is used to treat anal deformities, congenital defects and cosmetic disfigurements. The range of surgeries includes simple aesthetic procedures, as well as extensive sphincter reconstruction and anal strictureplasty. Plasty of hypertrophied anodermal folds is the most common cosmetic procedure. Anal deformations requiring surgical treatment include those causing anal canal deformation of functional importance. Perinatal injuries are the most common cause of this type of sphincter damage. Other include postoperative keyhole deformities and a ”gaping anus”. Another group of deformities includes anal stricture (postoperative, due to chronic inflammation in this region, post-traumatic or induced by radiation therapy) and lesions associated with the treatment of anal neoplasms. Surgical treatment of congenital anal defects is often initiated already in early childhood and performed by multidisciplinary teams led by paediatric surgeons. In the later period of treatment, these patients may require proctological interventions due to anal stricture or anal sphincter dysfunction as a result of surgeries. Plastic and reconstructive surgeries of the anal canal are mostly complex procedures requiring experience and should be performed in reference centres. Appropriate patient qualification and preparation for surgical treatment seem to be essential. Preoperative imaging and functional diagnosis is of key importance.
