Purpose: We aimed to show the outcome of very early endoscopic dacryocystorhinostomy (VE-EDCR) in a routine pool of patients with acute dacryocystitis (AD) and abscess formation compared with the standard late external dacryocystorhinostomy L-ExDCR.
Methods: This was a prospective nonrandomized comparative study conducted from June 2013 to March 2016. Patients with AD and abscess formation were referred to our oculo-facial clinic in a university-based hospital. All patients received systemic antibiotics and were assigned to either of treatment groups. Patients in group 1 underwent late external transcutaneous DCR (L-ExDCR) and group 2 underwent EDCR within 3 days after first visit, named VE-EDCR. Primary outcome measure was success of surgery.
Results: Forty-one eyes of 41 patients with acute suppurative AD, were included from June 2013 to March 2016. Twenty-two patients underwent VE-EDCR and 19 underwent L-ExDCR. Mean age of patients was 43.41 (SD = 19.84, range 14-98) years. Mean follow-up was 14 (SD = 2.4) months. Anatomic, functional, and overall success in L-ExDCR and VE-EDCR groups were (89.5 and 86.4%, p = 0.99) (89.5% and 86.4%, p = 0.99) (89.5% and 81.8%, p = 0.66) respectively. Mean duration of cellulitis in VE-EDCR and L-ExDCR were 8.00 (SD = 4.63) and 16.11 (SD = 11.58) days, respectively (p = 0.027). No remarkable adverse event was found.
Conclusions: Success of very early endonasal endoscopic DCR is comparable with the traditional late external DCR. Duration of cellulitis is shorter in VE-EDCR. This therapeutic approach can be considered in patients with acute suppurative dacryocystitis.
