Overview
Medical Therapy
- For many years up until 1995, customary treatment included warm baths, topical anesthetics, stool bulking agents, mechanical anal stretching, and, sometimes, surgery. In 1995, doctors began using nitroglycerine cream (topical 1 percent isosorbide dinitrate) but found it less acceptable for long-term use due to patients developing a tolerance to the drug. In 1998, Italian researchers reported injecting botulinum toxin into the anal sphincter to promote healing by relieving anal spasm through relaxation of the muscle.
- Most common cause of anal fissure is straining when constipated. For treatment of constipation, click here
Symptomatic
- Most anal fissures are shallow or superficial (less than a quarter of an inch or 0.64 cm deep). These fissures self-heal within a couple of weeks. Furthermore, the treatment used for hemorrhoid such as eating a high-fiber diet, using a stool softener, taking a painkiller and having a sitz bath can help.
- Preferred regimen, Sitz bath: anus to be immersed in warm water for 10-15 minutes q8-12h.[1][2][3]
Pediatric
- Anal fissures in infants usually self-heal without anything more than frequently changing diapers and treating constipation if it is the cause.
Chemical Sphincterotomy
- Painful deep chronic fissures, will not heal because of poor blood supply caused by sphincter spasm. Traditionally, surgical operations were required which are both painful and associated with various long-term complications, particularly incontinence in a small proportion of cases.
- Local application of medications to relax the sphincter muscle, thus allowing the healing to proceed, was first proposed in 1994 with nitroglycerine ointment,[4][5][6] in 1999 with nifedipine ointment,[7][8] and the following year with topical diltiazem.[9]
- Botulinum toxin injection, administered by colorectal surgeons, can also be used to relax the sphincter muscle and its use for this condition was first investigated in 1993.[10] Combination of medical therapies may offer up to 98% cure rates.[11] These medical treatments are used as first line therapy in treating chronic anal fissures,[12] although a Cochrane Collaboration review of published research has questioned the effectiveness of medical treatments compared to surgery.[13]
Topical medical therapy
The topical therapy is the first line of treatment along with dietary and other conservative measures. Analgesia and vasodilators are chiefly used for the topical management.[3][14][15][16][17][18]
Topical analgesic
- Preferred regimen: Lidocaine jelly 2-5% to be applied locally as needed.
Topical vasodilators
- Preferred regimen (1): Nitroglycerin 0.2 or 0.4% ointment to be applied rectally q12h for 8 weeks.
- Preferred regimen (2): Nifedipine 0.2-0.3% ointment to be applied topically q6-12h.
- Alternative regimen (1): Diltiazem 2% rectal gel q8h for 8 weeks.
- Alternative regimen (2): Bethanechol 0.1% rectal gel q8h for 8 weeks.
