Multicenter Study for Diagnosis and Treatment of Perianal Abscesses

Condition(s) studied

Investigational drug(s) / intervention(s)

Perianal abscess drainage: The patientens will be randomly selected and after they have taken part and said yes to the study, half the group will undergo examination with ultrasound and half without. After this random selection all the patients abscess will be drained.

3D ultrasonography: The patientens will be randomly selected and after they have taken part and said yes to the study, half the group will undergo examination with ultrasound and half without. After this random selection all the patients abscess will be drained.

Study summary

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.

Eligibility

Primary outcome measure(s)

• adverse events — up to one year
  Patients will be assessed in the outpatient clinic after 2 months and 1 year after surgical treatment. Eventual complications may include anal sepsis, recurrence of anal abscess and fistula formation.
