Potential Complications with Fissure Surgery
During fissure surgery recovery there is a chance that the patient may experience complications. Infection is rare and only affects one to two percent of patients. If the patient is prone to infection, is immunosuppressed, or has associated cellulitis, they may be prescribed a course of antibiotics after the surgery to help prevent an infection.
Bleeding can occur around the site of the fissure removal. Most cases are not serious and cases of bleeding in which therapy is required is extremely rare.
Less that one percent of all patients may experience an anal fistula developing at the sphincterotomy site. If an anal fistula develops, a fistulotomy should be performed to treat it. If these do develop they are most often superficial and low.
Patients may experience incontinence, but the rate of incidence is not exactly known because the definition and incidence of incontinence varies so much from study to study among the different fissure surgeries and procedures.
Some patients may experience their fissure either not healing or recurring. After surgical care, it is estimated that one to six percent of patients experience either non-healing or a recurrence of their fissure. Medscape states that as much as 50 percent of patients who experience non-healing or recurrence experience this due to undiagnosed, underlying Crohn's disease.
