Nasolacrimal Ducts

BackgroundDacryolith-induced epiphora is caused by a chronic obstruction of the nasolacrimal duct whose aetiology is often specified peroperatively. Dacryocystorhinostomy (DCR) has been often regarded as the gold standard to treat dacryolithiasis. Hasner’s valve (HV) incision is a technique to evacuate lithiasis through its physiological track. The purpose of this study was to describe clinical and radiological findings associated with presence of dacryoliths in patients who underwent surgery and to assess the efficacy of these two procedures.MethodsThis study was a comparative interventional multicentric retrospective study including patients referred for an epiphora. The primary endpoint was to determine clinical and endoscopic findings associated with dacryoliths. The secondary endpoints were to evaluate the performance of CT dacryocystography (CT-DG) in the diagnosis of dacryoliths and the success rate of the surgical treatment 6 months postoperatively.Results4677 nasolacrimal ducts (NLDs) (78.0% female, mean age 59.2) were included in the study. 3913 underwent DCR, and 764 underwent HV incision. 291 out of 4677 NLDs (6.2%) were found to have dacryoliths. Presence of mucocele associated to a permeable lacrimal system (OR 8.17 (95% 4.62 to 14.44), p<0.01) was associated with presence of lithiasis peroperatively. Success rates at 6 months were 95.6% for endonasal DCR and 94.6% for incision of HV in dacryolithiasis group (p<0.01). CT-DG had a negative predictive value of 96.3% to detect lithiasis (p<0.01).ConclusionStrong clinical and endoscopic findings may improve the imputability of dacryoliths in epiphora. Evacuation of dacryolithiasis through its physiological track was first described in this study in adults with similar results to DCR in patients presenting with dacryolithiasis.

Purpose This prospective study was designed to establish whether it is more effective to treat symptomatic congenital nasolacrimal duct obstruction by probing, or high-pressure irrigation, or both. Methods During the period February 1991 to January 1999, 228 infants (300 nasolacrimal ducts) were examined (132 males, 96 females, age range 12–13 months). These patients were divided into three groups of 100 ducts each. The first group was probed only; in the second group the nasolacrimal ducts were irrigated under high pressure using methylene blue-stained saline, and the third group was probed and irrigated in the same setting. The procedures were done under light general anesthesia. Results Ninety-one ducts in the first group improved after probing. In the second group 64 ducts improved after irrigation. In the third group 96 ducts improved after both probing and irrigation. Conclusions To treat symptomatic congenital nasolacrimal duct obstruction, it is more effective to combine high-pressure irrigation and probing. This gives a better success rate, first in treatment and secondarily, permitting intraoperative verification of the patency of the excretory lacrimal system.

Preliminary Study

Abstract Nasolacrimal duct obstruction is a common disorder which clinically manifests as epiphora. Many procedures have been described to bypass this obstruction, for example external dacryocystorhinostomy (DCR), endoscopic DCR with and without stents, Laser endoscopic DCR. Each of these procedures has its own success rates and complications. We did an analysis of all laser assisted endonasal DCR performed in our department from Feb 2006 to July 2009. In all we had operated 237 total cases out of which 203 were with normal endonasal DCR and 34 cases were Laser transcanalicular endonasal DCR (Laser DCR). Over all success rate was 92%(218 cases). In case of Laser assisted endonasal DCR the success rate was 70.3% (19 cases) with failure rate of 29.7% (8 cases) at three months follow-up. This preliminary study reveals that LASER DCR is associated with higher failure rates as compared to the normal endonasal DCR.

AbstractObjective:To assess the efficacy of an endonasal dacryocystorhinostomy technique using conventional instruments, without the use of any adjunctive techniques.Study design:Prospective, non-randomised, cohort study.Methods:Patients diagnosed with nasolacrimal duct obstruction between January 2006 and December 2008 were included in the study. Seventy-eight endonasal dacryocystorhinostomies (primary or revision) were performed with conventional ‘cold steel’ instruments. The technique involved complete exposure and marsupialisation of the lacrimal sac. No adjunctive procedures were used. Success was defined as complete resolution of epiphora and a patent lacrimal system, evaluated by lacrimal irrigation and endoscopy, one year post-operatively.Results:Seventy-four of the 78 cases were symptom-free after a minimum follow up of 12 months, giving an overall success rate of 94.9 per cent. The success rates for primary and revision cases were 95.5 and 90.9 per cent, respectively.Conclusion:Meticulous surgical technique can ensure high success rates with the use of conventional cold steel instruments, without the use of adjunctive procedures, making endonasal dacryocystorhinostomy a cost-effective, reliable procedure.

Dacryocystorhinostomy (DCR) is the ‘gold standard’ treatment for nasolacrimal duct obstruction (NLDO). However, despite its recent technical advancements, complications are possible. Herein, to the best of our knowledge, we present the first reported case of delayed unilateral pneumocephalus after bilateral endoscopic DCR. An 85-year-old man with bilateral NLDO underwent endoscopic DCR with silicone intubation. After 1 month, he became lethargic and was admitted to emergency room. Brain CT demonstrated left pneumocephalus and a suspected microfistula in left orbital wall. Intravenous antibiotic therapy was started, and cerebrospinal fluid studies showed no evidence of meningitis. After 13 days of antibiotic treatment, his mental state recovered with no signs of pneumocephalus. Although DCR has high success rate and is relatively safe, surgeons should be aware of the risk, although low, of pneumocephalus, especially in elderly patients who are vulnerable to fractures and who exhibit headache or mental status changes after endoscopic DCR.

Portal hypertension (PHT) leads to several alterations on hematological indices (HI). The aim of the study is to investigate the differences in HI between cirrhotic subjects and subjects who have noncirrhotic PHT (NCPHT). This retrospective study included 328 patients with PHT (239 cirrhosis and 89 NCPHT). Demographic and clinical features, endoscopic and radiological findings, and HI including neutrophil to lymphocyte ratio (NLR) at the time of PHT diagnosis were recorded. Severity of cirrhosis was assessed according to the Child–Turcotte–Pugh (CTP) classification and Model for End-Stage Liver Disease (MELD) scores. Hematological abnormalities were found in 92.5% of cirrhotic patients and in 55.1% of patients with NCPHT (p < 0.001). While thrombocytopenia was the most common HI in patients with cirrhosis, anemia was the most prevalent HI in NCPHT group. In the cirrhotic group, the NLR was the only parameter to differentiate each CTP group from two others. The NLR value increased with the severity of cirrhosis (2.28 ± 0.14 in CTP-A, 2.85 ± 0.19 in CTP-B and 3.26 ± 0.37 in CTP-C). The AUROC of NLR was 0.692 for differentiating compensated cirrhotic patients from decompensated. Hematological abnormalities are more prevalent and more severe in cirrhotic patients compared to patients with NCPHT. NLR may be used to assess the severity of cirrhosis.

Umbilical Arterial Catheter

BackgroundUmbilical arterial catheter (UAC) insertion is a common procedure in the neonatal intensive care unit (NICU). Correct placement of the tip of the UAC at first attempt minimises handling of the infant and reduces the risk of infection and complications. We aimed to determine the accuracy of 11 published formulae to guide UAC placement.MethodsThis was a one-year prospective observational study in a tertiary NICU. Clinicians used their preferred formula for UAC insertion, with X-rays performed immediately post-procedure to check the tip position. Birth weight and measurements included in the 11 formulae were recorded within 48 hours. The gold standard insertion distance was defined as the distance from the abdominal wall to the mid-descending aorta, at T8 level on X-ray (range T6–T10). Insertion length using the 11 formulae was calculated and compared with this gold standard distance.ResultsOne hundred and three infants were included, with median (IQR) gestational age and weight of 28 (26–33.5) weeks and 980 (780–2045) g, respectively. The predicted value of the 11 formulae to place the UAC in correct position ranged from 51.0% to 73.8%. Formulae that involved direct body part measurements showed the highest predicted success rates, smallest mean difference from T8 and narrowest limits of agreement using the Bland-Altman method.ConclusionSuccess rates for accurate UAC placement are highest when formulae that involve body measurements are used. However, even the most accurate method would result in more than 25% of UACs needing manipulation to achieve an optimal position.

Aims and Objectives: To compare the success rates of non endoscopic endonasal dacryocystorhinostomy and conventional external dacryocystorhinostomy for the surgical management of primary acquired nasolacrimal duct obstruction. Materials and methods: A retrospective, nonrandomized, comparative interventional case series of 302 patients who underwent either endonasal or external dacryocystorhinostomy over a period of 2 years. All surgeries were performed by a single surgeon and patients with primary nasolacrimal duct obstruction with a minimum of 6 months post operative follow up were included in the study. While external dacryocystorhinostomy was performed using traditional technique, endonasal dacryocystorhinostomy was performed using direct method of nonendoscopic visualization. Results: Of the 302 cases included in the study 165 patients had endonasal dacryocystorhinostomy whereas 137 underwent external dacryocystorhinostomy. Success was defined by resolution of symptoms of tearing, a negative fluorescein dye disappearance test and patency of the canalicular system on lacrimal irrigation. In the external dacryocystorhinostomy group 124 (90.5%) patients had surgical success whereas 146 (88.5%) of the endonasal dacryocystorhinostomy patients had successful outcome. The overall success rate was 89.4%, and the difference of surgical success between the two groups was not statistically significant ( P=0.57). Conclusion: Non endoscopic endonasal dacryocystorhinostomy gives surgical results comparable to those of external dacryocystorhinostomy and is a viable alternative where dacryocystorhinostomy is indicated for primary acquired nasolacrimal duct obstruction.

Objectives: To examine the frequency in which angled endoscopes are necessary to visualize the true maxillary ostium (TMO) following uncinectomy and prior to maxillary antrostomy. Additionally, to identify preoperative computed tomography (CT) measures that predict need for an angled endoscope to visualize the TMO. Study Design: Retrospective study. Setting: Tertiary academic hospital. Patients and Methods: Patients who underwent endoscopic sinus surgery (ESS) between December of 2017 and August of 2018 were retrospectively identified. Cases were reviewed if they were primary ESS cases for chronic rhinosinusitis without polyposis and if they were at least 18 years of age. Results: Sixty-three maxillary antrostomies were reviewed (82.5% were from bilateral cases). Thirty-five cases (55.6%) required an angled endoscope in order to visualize the TMO. Of the preoperative CT measures examined, a smaller sphenoid keel-caudal septum-nasolacrimal duct (SK-CS-NL) angle was significantly associated with need for an angled endoscope intraoperatively to visualize the TMO (17.1° SD ± 3.2 vs 15.0° SD ± 2.9; P = .010). Conclusion: Angled endoscopes are likely required in the majority of maxillary antrostomies to visualize the TMO. This is important to recognize in order to prevent iatrogenic recirculation. The SK-CS-NL angle may help to identify cases preoperatively which require an angled endoscope to identify the TMO during surgery.
