Treatment of acute dacryocystitis by translacrimal canalicular drainage and D-silicone intubation

AIM:To demonstrate the outcomes of translacrimal canalicular drainage using a lacrimal probe and intranasal drainage by D-silicone intubation for acute dacryocystitis(AD).METHODS:This retrospective study included 23 patients with AD and had undergone abscess decompression with the use of lacrimal probe and intranasal drainage by D-silicone intubation between January 2019 and December 2022.Patients received abscess decompression and systemic antibiotic-corticosteroid from the time of diagnosis.D-silicone tube was inserted within 10d after diagnosis and removed 3-6mo after intubation.The procedure and outcomes of this method were evaluated.RESULTS:All patients showed improvement of signs and symptoms of AD within 72h.No intraoperative and postoperative complications were observed.No recurrence of lacrimal sac abscesses occurred after D-silicone tube removed.CONCLUSION:Lacrimal probe and D-silicone intubation appear to be a feasible,minimally invasive,safe,and effective method,which could be a reasonable choice in the treatment of AD.

Endoscopic dacryocystorhinostomy in acute dacryocystitis:a multicenter study in China

AIM:To repor t the clinical profile,endoscopic dacryocystorhinostomy(En-DCR)management,and acute dacryocystitis(AD)outcomes in China.METHODS:Clinical data of 554 adult AD patients(554 eyes)who presented in 7 tertiary eye care centers for 10y from Jan 2010 to Mar 2020 were retrospectively analyzed.Clinical profile,En-DCR management,and outcomes of all cases were recorded.The anatomical and functional success were evaluated for 12mo post-operation.RESULTS:The analysis included 149 males and 368 females with a median age of 55.2y(range:18-84y).There were 459 eyes with a history of epiphora or purulent secretion.The time between a symptom of lacrimal duct obstruction and acute onset was 1 to 540(66.1±58.2)mo.Fifty-nine eyes had a history of the previous acute attack.Seventy-four eyes developed a cutaneous fistula,while 11 eyes had post septal cellulitis pre-operation.En-DCR with an anatomical success of 91.7%and functional success of 90.1%.The success rate of the patients with a history of acute episodes and the preoperative fistula was lower than the overall success rates.CONCLUSION:En-DCR can be performed during an acute episode in AD with a success rate of over 90%.

Surgical outcomes in acute dacryocystitis patients undergoing endonasal endoscopic dacryocystorhinostomy with or without silicone tube intubation

AIM:To establish the necessity of silicone tube intubation in acute dacryocystitis(AD)patients undergoing endonasal endoscopic dacryocystorhinostomy(En-DCR).METHODS:Patients presenting with unilateral AD were randomly assigned to two treatment groups.En-DCR procedures were performed following lacrimal abscess formation,with the operation being performed with silicone intubation for patients in group B but not group A.Functional success was defined by an absence of additional AD episodes,no epiphora,and ostium patency as established via endoscopic evaluation or fluorescein irrigation.Operative success rates and demographic variables were compared between treatment groups.RESULTS:In total,66 patients were analyzed in the present study(33 per group),with complete postoperative data having been successfully collected from 27 and 22 patients in group A and group B,respectively.All patients exhibited complete resolution of acute inflammation.Upon follow-up,granulation tissue was detected around the ostium at higher rates in group B(9/22,40.9%)relative to group A(4/27,14.8%).At the 12-month follow-up time point,patients in group A exhibited higher success rates(25/27,92.6%)relative to patients in group B(20/22,90.9%),but this difference was not significant.Cases of lacrimal passage reconstruction failure in both groups were attributed to excessive fibrous and/or granulation tissue formation proximal to the intranasal ostium.CONCLUSION:Given that these two operative approaches are associated with similar rates of operative success and in light of differences in granulation tissue formation,cost,and operative duration,these data do not support the routine silicone intubation of AD patients following En-DCR surgery.

Computed tomography for guidance in the diagnosis and surgical correction of recurrent pediatric acute dacryocystitis

Importance:This is the first retrospective study of the effect of computed tomography(CT)in diagnosis and surgical correction of recurrent pediatric acute dacryocystitis(PAD).Objective:To explore the pathogenesis of recurrent PAD and the impact of CT in guidance of surgical planning.Methods:Medical histories,clinical manifestations,and CT results of 10 patients with recurrent PAD were reviewed.Etiologies and treatment effectiveness were recorded for all patients.results:CT revealed that three patients had congenital dacryocystocele with lacrimal sac cyst,enlargement of the nasolacrimal canal,and intranasal cyst of affected sides.After regression of local inflammation,marsupialization was performed.CT showed that four patients had PAD secondary to congenital nasolacrimal canal dysplasia;these patients exhibited normal upper portions of the nasolacrimal canals,but had stenotic or atretic middle and terminal segments.After improvement of local inflammation,endonasal dacryocystorhinostomy was performed.Three patients had PAD secondary to congenital lacrimal sac diverticulum;after contrast injection,CT showed that the cysts at the lacrimal sac area were filled with contrast,and were connected to the normal lacrimal sac.After the topical infection was controlled,transcutaneous dacryocystorhinostomy was performed in combination with excision of the lacrimal sac diverticulum.No recurrence of PAD was detected at 6-month follow-up.Interpretation:Causes of PAD include congenital dacryocystocele,congenital lacrimal sac diverticulum,or congenital nasolacrimal canal dysplasia.Marsupialization with endoscope,endonasal dacryocystorhinostomy,and transcutaneous dacryocystorhinostomy constitute distinct surgeries for PAD treatment.CT provides an important diagnostic function and facilitates selection of specific surgical approaches for recurrent PAD.
