Bicanalicular Lacerations: Clinical Characteristics and Surgical Outcomes With a New Bicanalicular Silicone Stent.

Bicanalicular lacerations are relatively rare and more of a surgical challenge in clinical practice. The purpose of this study is to evaluate the clinical characteristics and surgical outcomes of bicanalicular lacerations with a new bicanalicular silicone stent at a tertiary eye care center. All patients who underwent bicanalicular lacerations repair from January 2013 and December 2018 were retrospectively reviewed. Data collected for each patient included patient demographics, affected sides, cause of injuries, the timing of management, associated ocular injuries, the timing of stent removal, duration of follow-up and the outcomes of the surgical repair with a new bicanalicular silicone stent. Thirty-six patients with bicanalicular lacerations met the inclusion criteria and were enrolled in the study. The mean age of the patients was 43.8 years old (range: 2-73years). Of the 36 patients, 33 (91.7%) were males and 3 (8.3%) were females. The right eye was injured in 17 patients (47.2%). All patients underwent surgical intervention within 24 hours. The most common cause of bicanalicular lacerations was electric bicycles accidents (7 patients, 19.4%), and followed by motor vehicle accidents (6 patients, 16.7%), blunt objects (6 patients, 16.7%), fights (6 patients, 16.7%), falls (3 patients, 12%), dog bites (2 patients, 5.6%), hook injuries (2 patients, 5.6%), broken glass (2 patients, 5.6%), and sharp objects (2 patients, 5.6%). The most common associated ocular injuries were orbital fracture (61.1%), followed by lid lacerations and open globe injuries. The functional success rate was 86.1%. The average interval between the surgery and the stent removal was 13.8 weeks (range: 8-20 weeks). All the stents were removed successfully without any difficulty in the outpatient department. The follow-up after stent removal ranged from 2 to 12 months (mean: 5.1months). Bicanalicular lacerations involvement occured in 6.8% of all canalicular lacerations. The most common cause of bicanalicular lacerations was electric bicycles accidents and the most common associated ocular injuries was orbital fracture in North China. The new bicanalicular silicone stent achieved good functional success (86.1%) in the management of bicanalicular lacerations.

The Study of a New Modified Bicanalicular Intubation for the Repairment of Traumatic Canalicular Laceration.

Introduction To investigate the efficacy and safety of a modified bicanalicular intubation (MBCI) used in canalicular laceration. Materials and Methods This study is a retrospective consecutive chart review. A total of 43 eyes from 43 patients (36 males and 7 females) who underwent canalicular intubation were enrolled. Success rate was determined at 6 months after the surgery. Anatomical success was determined by diagnostic probing and irrigation; functional success was determined by asking patients about tearing. Results Irrigation of the lacrimal passages in all 43 eyes showed that they were free from obstruction. The anatomical success was 100%, and 37 eyes (86%) achieved functional success. 6 eyes (14%) could not achieve functional success because there were some residual symptoms under irritating conditions, such as wind or winter weather, among which 2 eyes had bicanalicular lacerations and 4 eyes had lower canalicular laceration before surgery. There were no other complications observed in this study. Conclusions The MBCI was simple and safe for using in canalicular laceration.

A new method for locating the proximal lacerated bicanalicular ends in Chinese preschoolers and long-term outcomes after surgical repair.

This report is to explore the long-term outcomes of surgical repair of bicanalicular lacerations in Chinese preschool patients. In this report, 12 patients with bicanalicular lacerations were studied between September 2010 and September 2015. The distance from the punctum to the distal canalicular lacerated end was recorded before surgery to classify different types of trauma. All patients underwent surgical repair of the lacerated canaliculi by 1 surgeon within 48 hours after the trauma occurred. After treatment, the lesions were divided into 3 types according to the distance from the punctum to the distal lacerated canalicular end as follows: lateral, medial, and the central. Based on this classification, each lacerated canaliculus was successfully repaired. Nearly half of the lesions (46%) were lateral, 42% were central, and 12% were medial. The average time for locating the proximal lacerated end of the canaliculus was 3.33 ± 1.52 minutes (range, 1.0–7.0 minutes). The follow-up time ranged from 6.0 months to 4.5 year (median, 25 months). Our study showed that 96% (23) of the canaliculi were completely patent. One lateral lesion presented with residual outdoor epiphora in cold weather secondary to left lower canalicular stenosis. All 12 patients had excellent cosmetic results. Our study displayed a surgical management based on the 3 types of lesions helped to find the proximal lacerated end of the canaliculus, and provided excellent long-term outcomes of drainage function.

Old canalicular laceration repair: a retrospective study of the curative effects and prognostic factors.

To investigate the epidemiology and surgical outcomes of old canalicular laceration and analyze the variables impacting on the prognosis of reparation. A retrospective review of all old canalicular laceration repairs from Jan. 1, 2008 to Dec. 30, 2015 was performed. Analyzed data included demographics, mechanisms of injury, the time from injury to repair, causes for delayed repair, old associated injuries, the types of surgery, and the effects of repair using canaliculus anastomosis combined with bicanalicular stent intubation. Totally 148 patients with old canalicular laceration received surgical repair and were enrolled. The mean age at presentation was 32.52 years old (ranged from 3 to 63 years old). The 110 patients (74.32%) were male and 127 patients (85.81%) were adults (≥18 years old). The old upper, lower, and bicanalicular lacerations were found in 5 (3.38%), 39 (26.35%), and 104 patients (70.27%), respectively. The mechanism of old injury was primarily due to motor vehicle accidents (n=53, 35.81%). The mean time from injury to repair was 43.61mo (ranged from 1 to 360mo). Associated old ocular and orbit injuries were found in 65 patients (43.92%), and chronic dacryocystitis in 18 patients (12.16%). The main cause of delayed repair was that doctors or patients didn't pay attention to the canalicular laceration because of the concurrent severe injuries (n=71, 47.97%). Totally 136 patients (91.89%) with old canalicular laceration underwent canaliculus anastomosis combined with bicanalicular stent intubation. In all of them, 20 patients (13.51%) were combined with dacryocystorhinostomy. In these cases, 132 patients (97.06%) attained anatomic success, 121 patients (88.97%) reported no epiphora (functional success), 11 patients (8.09%) reported significant epiphora anesis (functional improvement), and 4 (2.94%) reported no significant anesis (functional failure). Rates of anatomic success and functional success were significantly correlated with different canaliculus involved. However, rates of anatomic success and functional success were not significantly affected by the time from injury to repair. The canalicular anastomosis combined with bicanalicular stent intubation could act as an effective therapeutics for old canalicular laceration.

Canalicular lacerations: Factors predicting outcome at a tertiary eye care centre

ABSTRACTTo determine the factors predictive of outcome in canalicular laceration repair at a tertiary eye care centre. A retrospective review of the medical records of all primary canalicular laceration repairs managed at a tertiary eye care centre between the years 2006 and 2014 was done. Thirty-nine patients were included and majority were male (79.5%) with a mean age of 30.05 + 16.2 years (range 2–65). Most (n = 34) had monocanalicular laceration and 5 had bicanalicular laceration. All surgeries were done in the operating room setting. Overall patency by irrigation was seen in 74.4% at a median follow-up of 19.89 weeks (range 21–910). Anatomical outcome was different among the stents and best after Mini-Monoka monocanalicular stent (17/19; 89.5%) followed by bicanalicular annular stents (n = 6; 60%) and 20G Silicone rod (8/14, 57%). The factors predictive of poor outcome were related to the mode of injury [road traffic accidents; Hazard ratio (HR)19.57; p = 0.048] and the type of stent [20G silicone rod (HR 35.7; C.I 3.04 - 419.14; p = 0.004)] by multivariate analysis. Skill of the surgeon was critical as the outcome for fellows-in-training showed a trend towards failure (HR 6.66, p = 0.07). Complications included stent extrusion (n = 28.2%), punctal granuloma (n = 5.1%) and stent exposure (n = 2.5%). The mode of injury - road traffic accidents and type of stent - 20 G silicone rod were risk factors predictive of poorer outcome after canalicular laceration repair. Individual skill of operating surgeon may be a critical factor suggesting a review of training protocols.

Is the distance from punctum a factor in the anatomical and functional success of canalicular laceration repairs?

Purpose:The aim is to analyze the influence of the location of lacrimal canalicular laceration over the eventual anatomical and functional success after surgery.Methods:Retrospective, observational study of proximal canalicular laceration (PCL) and distal canalicular laceration (DCL) repairs by a single surgeon (MS). The distance between lacrimal punctum and the lateral canalicular lacerated end was defined as proximal (<6 mm) and distal (≥6 mm). The operation theater setup, microscopic magnified view, local adrenaline, and pigtail probe were used to locate the medial canalicular lacerated end. All patients underwent lacrimal stenting and the stents were removed after 3 months (12th week visit). After stent removal, a fluorescein dye disappearance test and lacrimal irrigation were performed to assess the anatomical and functional success of the operation.Results:Of 36 canalicular lacerations, 30 (83.33%) were monocanalicular lacerations which were repaired using monocanalicular stents. Of 6 (16.67%) bicanalicular lacerations, three were repaired using bicanalicular stents while in the remaining three, one monocanalicular stent was placed in each lacerated canaliculi. The medial cut end was identified by magnified visualization in 27 (75%), with adjunctive local adrenaline in four (11.11%) and pigtail probe in five (13.89%) patients. The mean post stent removal follow-up was 44 weeks. The DCL (n = 24, 66.67%) showed better functional and complete success as compared to PCL (75% vs. 33.33%, P = 0.03). Eight (22.22%) had spontaneous stent extrusion, two (5.56%) had loop prolapse, four (11.11%) had punctum granuloma, and three (8.33%) had medial canthus dystopia.Conclusion:The location of canalicular laceration may help to prognosticate the functional and qualified success rate. We experienced better-qualified success in the distal canalicular laceration group.

A simplified approach for bicanalicular silicone tube intubation for the management of canalicular lacerations

We report the surgery of a bicanalicular laceration of the lacrimal system in which a simplified annular intubation of silicone tube had been used. After passing the silicone tube through the canalicular system guided by the prolene suture, the tip of the silicone tube was stuck and advancing it through the lach - rymal system was not possible. Then this threaded 6-0 prolene suture was tied to the wall of the silicone tube at the tip and pulled gently from the opposite side. The silicone tube was threaded easily with no obstacle. We hope that our result in this case will create an alternative way for surgeons while repairing canalicular system lacerations

Outcome after Repair of Concurrent Upper and Lower Canalicular Lacerations

Purpose: To investigate the functional and cosmetic results after primary surgical repair of bicanalicular lacerations.Methods: We identified patients diagnosed with bicanalicular lacerations at the Eye Clinic of Rigshospitalet, Copenhagen from 2000 through 2009. Patient charts were reviewed and a telephone interview was conducted according to a standard questionnaire, regarding tearing and cosmesis. Symptoms (no epiphora, epiphora only when outdoors, epiphora when indoors, or epiphora with discharge) were compared to the healthy eye and scarring was graded from 0 to 10 by the patient (none to very disturbing).Results: Fifteen patients had bicanalicular lacerations. Canalicular silicone stents were used in six different ways: two monostents to the lacrimal sac (n = 1), one monostent to the nose in the upper canaliculus (n = 2), two monostents to the nose (n = 2), bicanalicular stent to the nose (n = 7), bicanalicular anular stent (n = 2), bicanalicular stent and dacryocystorhinostomy (n = 1). The surgery was carried out by 6 different surgeons. Eleven patients could be followed up. In these, epiphora was reported after primary surgery by 7 patients, and scarring was graded to more than 1 in 4 patients. However, it is noteworthy that 3 of 4 patients operated with monostents had no symptoms; the fourth patient reported having epiphora indoors. Furthermore, the four patients operated with monostents graded their scaring to be 0 (n = 3) or 1 (n = 1) only.Conclusion: Sequelae are common after bicanalicular lacerations. The use of one or two monostents to the nose appears to be a reasonable alternative to the traditional use of one bicanalicular stent.

One-stitch anastomosis through the skin with bicanalicular intubation: a modified approach for repair of bicanalicular laceration.

To evaluate the efficacy and safety of one-stitch anastomosis through the skin with bicanalicular silicone tube intubation in repairing of bicanalicular laceration. The clinical data of 15 consecutive patients with both superior and inferior canalicular laceration in one eye who underwent surgical repair using one-stitch anastomosis through the skin and bicanalicular stent were retrospective studied. All the operations were performed under surgical microscope, 5-0 silk sutures were used and were with bicanalicular silicone tube (diameter was 8mm) intubation, for one lacerated canaliculi one-stitch anastomosis through the skin. The stents were left in place for 3 months postoperatively and then removed. The follow-up period was 3 - 36 months (average 14 months). In 15 patients, 13 patients were cured entirely, 1 patient was meliorated, 1 patient with no effects. All patients had got good recovery of eyelid laceration with no traumatic deformity in eyelid and canthus. Complication was seen in one case, for not followed the doctor's guidance to come back to hospital to had the suture removed on the 7(th) day after operation, when he came at the 15(th) day, the inferior canalicular wall and eyelid skin were corroded by the suture caused 2mm wound, and the inside silicone tube was exposed, a promptly repair with 10-0 nylon suture was done, the wound healed in a week. There were no early tube protrusions and punctal slits in the patients. One-stitch anastomosis through the skin with bicanalicular silicone tube intubation is a good method in repair of bicanalicular laceration in one eye, the cut ends can be anastomosed directly, and with excellent cosmetic results, it is acceptable for the patients. For there is no suture remained in the wound permanently, so there is no suture-related granuloma which may cause obstruction or stenosis of canaliculi. It is simple, economical, effective and safe.

Bicanalicular Laceration Repair Via an Endoscopic Retrograde Approach

A 31-year-old man presented 5 days after a left bicanalicular laceration from trauma. Identification of the medial cut ends under direct visualization was unsuccessful. A retrograde endoscopic approach was used to identify the common canaliculus or one of the medial cut ends of the canaliculi by injecting the lacrimal sac with saline and observing fluid egress from the wound. Both canaliculi were stented with a silicone tube and both ends of the tube were passed through the identified medial opening in the lacrimal sac. The tubes were retrieved from the nose and tied, and then left for 6 months before removal. The patient did not complain of epiphora and demonstrated bicanalicular patency on irrigation. This is the first description of using an endoscopic retrograde approach to identify the medial ends of a bicanalicular laceration.

Effectiveness of canalicular laceration repair using monocanalicular intubation with Monoka tubes

This study aimed to evaluate the clinical efficacy of canalicular laceration repair using monocanalicular intubation with Monoka tubes. A total of 36 single lacerated canaliculi were repaired using monocanalicular intubation with Monoka tubes, without mucosal anastomosis of the canaliculi, and were retrospectively reviewed. Demographic information, injury locations, associated ocular injuries, complications and outcomes were analysed. Mean patient age was 34 years (range 1-64 years). Tubes were removed at a mean of 4.2 months (range 3-6 months). There were 26 lower canalicular lacerations (72%) and 10 upper canalicular lacerations (28%). Overall, 34 of 36 cases (92%) showed improvement in symptoms and exhibited positivity on the dye disappearance test at 4-12 months after the procedure (mean 7.8 months). In total, 21 patients (58%) achieved complete success, 13 patients (36%) achieved partial success and two patients (6%) suffered surgical failure. Complications were seen in five cases and included two early tube protrusions, two punctal slits and one punctal granuloma. Monocanalicular intubation with Monoka tubes leads to successful outcomes without significant complications and offers an alternative to bicanalicular intubation in the treatment of monocanalicular lacerations.

Bicanalicular Laceration Managed with Two Mini-Monoka® Monocanalicular Stents

Bicanalicular lacerations have been traditionally managed using bicanalicular nasal intubation or annular stents. The Mini Monoka monocanalicular stent has been described for the management of monocanalicular lacerations. A bicanalicular laceration can also be successfully managed using two Mini Monoka monocanalicular stents, and this technique has several advantages. We report this simple and minimally invasive alternative in the management of bicanalicular laceration.
