Outcomes and Reasons for Dacryocystorhinostomy (DCR) at KCMC, a Tanzanian referral hospital, 2001-2006

Background: External dacryocystorhinostomy (DCR) is a surgical intervention aimed to treat blocked nasolacrimal ducts of almost all causes. To date there is only limited data available from the Sub Saharan African setting.
Objectives: This study aimed to provide further information of the outcomes of DCR in Africa.
Methods: Records of all patients undergoing external DCR operations from January 2001 to April 2006 were systematically searched. 55 patients were identified and notes were available for 45 patients.
Results: Discharge and epiphora were resolved in 90.9% (30/33) and 84.4% (27/32) of patients respectively. Over half the cases (51.1%) were children. The commonest reason for operation was chronic dacryocystitis (51.1%). Outcomes for DCR were not significantly different for either children or adults and a clear improvement of symptoms was found in the vast majority of cases.
Conclusion: This study provides information on the outcomes of DCR in the African population. An 84.4% cure rate of epiphora and 90.9% cure rate of discharge is comparable with findings in other developing countries. This study supports the continued use of this intervention in skilled hands for treatment of blocked nasolacrimal duct.
