Bohman E, et al. - In this investigation involving 71 patients, researchers examined long-term outcome and report reoperation rate of non-infected, complete acquired lacrimal drainage obstruction (ALDO) treated with canaliculodacryocystoplasty (CDCP) depending stenosis site. Consecutive adult patients were followed for 76 months with non-infected, complete ALDO treated with CDCP. Survival analysis was used to compare the rate of reoperation according to the stenosis site. Of 85 cases, 57 have been classified as canalicular stenosis and 28 have been classified as preoperative nasolacrimal duct obstruction (NLDO). Data reported that 39% (33/85) of cases had required additional surgery due to persistent/recurrent symptoms at the end of follow-up. The treatment of complete NLDO with CDCP results in a high reoperation rate and appears to be an ineffective option. If preoperative examination shows canalicular stenosis or dacryocystorhinostomy is not suitable, canaliculodacryocystoplasty (CDCP) may be addressed. Nonetheless, the patient needs to be aware of the higher risk of further surgery, particularly if a second stenosis is detected during probing.
