AbstractObjectiveThis prospective, controlled study assessed how placing a stent into a newly formed ostium affects ostial patency, success and complication rates in endoscopic dacryocystorhinostomy patients.MethodsIn group 1 (40 eyes of 36 patients), both silicone tube intubation and tube stenting were performed. In group 2 (36 eyes of 34 patients), only silicone tube intubation was performed. Success, operative time and post-surgical complications were investigated two months post-operatively in each group.ResultsThe success rates were 92.5 per cent and 83.3 per cent for groups 1 and 2 respectively, but the difference was not statistically significant (p = 0.294). The complication rates also differed between the two groups, but this was again insignificant.ConclusionCompared with the use of a silicone tube alone, the addition of an ostial stent did not significantly increase the success rate of endoscopic dacryocystorhinostomy.

Dacryocystorhinostomy is widely considered as the standard treatment due to chronic nasolacrimal duct obstruction (NLDO). These procedures include standard external Dacryocystorhinostomy (DCR), non-laser endonasal endoscopic DCR (EN-DCR), and endonasal endoscopic laser DCR (LA-DCR)1. However external DCR is considered as the gold standard surgical method in the treatment of NLDO. Our study describes a comparative study of success rates of external DCR surgery, wherein 30 patients each were included for with and without silicone tube intubation usage respectively. The results showed a higher success rate (90%) in outcome of external DCR surgery using silicone tube intubation as compared to that without its usage (80%). Therefore, this study was aimed to shed further light on EXDCR surgery using intubation stents. The study also helps in shedding light on better post-operative management and obtaining higher success rates in case of EX-DCR surgery.

BackgroundIt is generally recommended to keep the wrist joint mildly dorsiflexed during radial artery catheterisation. However, wrist dorsiflexion might decrease the success rate of radial artery catheterisation with dynamic needle tip positioning technique. Therefore, we assessed the success rates of two groups with or without wrist dorsiflexion by 5 cm wrist elevation in adult patients.MethodsThis randomised controlled clinical trial was performed between March and December 2018 in the First Affiliated Hospital of Shantou University Medical College, China. We recruited 120 adult patients undergoing major surgical procedures and randomly allocated them into two groups: dorsiflexion group (group D) and neutral group (group N). The primary outcome was first-attempt success rates of two groups. Secondary outcomes were overall success rates within 5 min; numbers of insertion and cannulation attempts; overall catheterisation time; duration of localisation, insertion and cannulation; and complication rates of catheterisation.ResultsFirst-attempt success rate was 88.3% in group D and 81.7% in group N (p=0.444). The overall success rate within 5 min was 93.3% in group D compared with 90.0% in group N (p=0.743). Numbers of insertion and cannulation attempts, overall catheterisation time, duration of localisation and insertion, and complication rates did not show a significant difference between the two groups. Cannulation time was longer in group N (35.68 s) than that in group D (26.19 s; p<0.05).ConclusionWrist dorsiflexion may not be a necessity for ultrasound-guided radial artery catheterisation using dynamic needle tip positioning technique in adult patients.Trial registration numberChiCTR1800015262.

Objective: The aim of the present study was to investigate the effect of allergic rhinitis on the success of the operation in chronic otitis surgery by using score for allergic rhinitis (SFAR). Materials and Methods: In the present study; 121 patients, who underwent type 1 tympanoplasty were examined retrospectively. SFAR of all patients were recorded. The graft success rates of 26 patients with allergic rhinitis (AR) and 95 patients with no allergic rhinitis group (NAR) were compared. Results: While the graft success rate in NAR group was 89.5%, this rate was 80.8% in the AR group. However, the difference between groups was not statistically significant (p = 0.311). Conclusion: These findings suggest that allergic rhinitis decreases the graft success rate of the pathologies occurring in eustachian tube, middle ear and mastoid although statistically significant difference wasn’t found. Prospective studies with larger patient groups are required in order to evaluate this pathology.

Background. Bleb needling with subconjunctival injection of antimetabolites had become a widely accepted approach for trabeculectomy failure. However, IOP reduction effects, success rates, and complications occurrence for this procedure showed great inconsistency among the different studies. Methods. We conducted a literature search on PubMed, Embase, Cochrane Library, and ClinicalTrials.gov. A random-effects model was performed on the extracted data based on the included studies. The intraocular pressure (IOP) and number of antiglaucomatous medications before and after the surgery were pooled for meta-analysis. The success and complication rates were estimated based on the results. Subgroup analysis, sensitivity analysis, and metaregression were applied to explore the origination of heterogeneity. Results. Thirty-seven studies with a total of 2182 patients were finally included in our review. For the present meta-analysis, the overall effects of bleb needling at the last visit revealed a reduction in IOP of 9.74 mmHg (95% confidence interval (CI) [8.85, 10.63]), 45.9% (95% CI [39.0%, 53.0%]) for complete success rate, and 70.4% (95% CI [63.5%, 77.0%]) for qualified success rate. Application of mitomycin C (MMC) and 5-fluorouracil (5-Fu) during the procedure were efficacious for IOP control during the follow-up. Metaregression revealed that possible origination of heterogeneity was baseline IOP before bleb needling, revealing a trend that higher baseline IOP correlated with a greater IOP reduction results p < 0.001 . For safety profile, conjunctival haemorrhage (5.7%, 95% CI [2.5%, 10.1%]), hyphema (5.5%, 95% CI [3.0%, 8.7%]), and bleb leakage (5.0%, 95% CI [3.2%, 7.3%]) had the highest estimate of incidence. An increasing number of needling was the main risk factor for needling failure. Conclusion. Bleb needling with antimetabolites could be considered an effective and safe procedure after trabeculectomy failure. After the process, patients will gain IOP control and reduce antiglaucomatous medications for at least six months with 5-Fu or MMC. Meanwhile, the overall estimates for complications were relatively low in the whole process.

AbstractThere is limited evidence in literature determining age effect on outcomes of endoscopic dacryocystorhinostomy (EDCR) in adult patients with primary acquired nasolacrimal duct obstruction (NLDO). We aimed to analyze the outcomes of EDCR according to age in primary acquired NLDO. A retrospective study was performed on consecutive adult patients and patients were divided into two age groups; group 1 (aged to 61 years) and group 2 (aged 62 to 89 years) based on the average value. The minimum required follow-up period was 6 months. A total of 441 EDCRs performed in 342 patients were enrolled. The anatomical success rate was not significantly different between the two groups (91.8% and 88.2%, P = 0.209). However, the functional success rate was significantly lower in the group 2 (85.1% and 76.9%; P = 0.036). Functional failure was associated with old age and a history of diabetes mellitus (P  = 0.024 and P  = 0.008). In subgroup analysis of patients with anatomical success but functionally failed EDCR, group 2 had significantly more comorbid conditions such as eyelid laxity (P = 0.026). In conclusion, the comorbid conditions which increase with age may affect functional outcome, especially eyelid laxity, careful preoperative examination of the eyelid and conjunctiva should be emphasized to lacrimal surgeons before performing EDCR.

<p><strong>Introduction:</strong> Our aim was to demonstrate the effect of insicion of renal parenchyma during open renal stone surgery (ORSS) on percutaneous nephrolithotomy (PNL) outcomes.</p><p><strong>Methods:</strong> Patients with history of ORSS who underwent PNL operation between June 2005 and June 2015 were analyzed retrospectively. Patients were divided into two groups according to their type of previous ORSS. Patients who had a history of ORSS with parenchymal insicion, such as radial nephrotomies, anatrophic nephrolithotomy, lower pole resection, and partial nephrectomy, were included in Group 1. Other patients with a history of open pyelolithotomy were enrolled in Group 2. Preoperative characteristics, perioperative data, stone-free status, and complications were compared between the groups. Stone-free status was defined as complete clearance of stone(s) or presence of residual fragments smaller than 4 mm. The retrospective nature of our study, different experience level of surgeons, and lack of the evaluation of anesthetic agents and cost of procedures were limitations of our study.</p><p><strong>Results:</strong> 123 and 111 patients were enrolled in Groups 1 and 2, respectively. Preoperative characteristics were similar between groups. In Group 1, the mean operative time was statistically longer than in Group 2 (p=0.013). Stone-free status was significantly higher in Group 2 than in Group 1 (p=0.027). Complication rates were similar between groups. Hemorrhage requiring blood transfusion was the most common complication in both groups (10.5% vs. 9.9%).</p><p><strong>Conclusions:</strong> Our study demonstrated that a history of previous ORSS with parenchymal insicion significantly reduces the success rates of PNL procedure.</p>

Abstract OBJECTIVE To describe a frameless stereotactic technique used to resect cerebral arteriovenous malformations (AVMs) and to determine whether frameless stereotaxy during AVM resection could decrease operative times, minimize intraoperative blood losses, reduce postoperative complications, and improve surgical outcomes. METHODS Data for 44 consecutive patients with surgically resected cerebral AVMs were retrospectively reviewed. The first 22 patients underwent resection without stereotaxy (Group 1), whereas the next 22 patients underwent resection with the assistance of a frameless stereotaxy system (Group 2). RESULTS The patient characteristics, AVM morphological features, and percentages of preoperatively embolized cases were statistically similar for the two treatment groups. The mean operative time for Group 1 was 497 minutes, compared with 290 minutes for Group 2 (P = 0.0005). The estimated blood loss for Group 1 was 657 ml, compared with 311 ml for Group 2 (P = 0.0008). Complication rates, residual AVM incidences, and clinical outcomes were similar for the two groups. CONCLUSION Frameless stereotaxy allows surgeons to 1) plan the optimal trajectory to an AVM, 2) minimize the skin incision and craniotomy sizes, and 3) confirm the AVM margins and identify deep vascular components during resection. These benefits of stereotaxy were most apparent for small, deep AVMs that were not visible on the surface of the brain. Frameless stereotaxy reduces the operative time and blood loss during AVM resection.

The aim of this study was to evaluate the clinical results of patients with vesicoureteral reflux, which were treated with subureteral injection of small-size (80–120 μm) dextranomer/hyaluronic acid copolymer (Dx/HA). Data of 75 children (105 renal units) who underwent STING procedure with small-size Dx/HA for the treatment of vesicoureteral reflux (VUR) in our clinic between 2008 and 2012 were retrospectively analyzed. Preoperative reflux grade and side, injection indication, postoperative urinary infections and urinary symptoms, voiding cystourethrogram, and renal scintigraphy results were evaluated. The success rate of the procedure was 100% in patients with grades 1 and 2 reflux, 91% in patients with grade 3 reflux, and 82.6% in patients with grade 4. Overall success rate of the treated patients was 97%. Endoscopic subureteric injection with Dx/HA procedure has become a reasonable minimally invasive alternative technique to open surgery, long-term antibiotic prophylaxis, and surveillance modalities in treatment of VUR in terms of easy application, low costs and complication rates, and high success rates. Injection material composed of small-size dextranomer microspheres seems superior to normal size Dx/HA, together with offering similar success with low cost.

Background. Endovascular strategies have been used to manage patients with thrombosed vascular access for hemodialysis. We analyzed primary success rate and patency rates of balloon angioplasty following mechanical thrombectomy for the treatment of thrombosed native arteriovenous fistulas.Methods. This was a retrospective study of 24 patients with thrombosed native arteriovenous fistulas who were referred for treatment in the intervention unit of the Radiology Department. All patients had been performed percutaneous thrombo-aspiration and balloon angioplasty. Technical and clinical success rates as well as the 6th and 12th months primary and secondary patency of fistulas were evaluated .Results. Technical and clinical success was 83%. In the 6 of 20 patients, early re-thrombosis were detected. Patent AVF with primary and secondary patency rates at 6 and 12 months was 55%-40%. The secondary patency rates at 6 and 12 months were 75% and 70%.Conclusion. Mechanical thrombectomy with balloon angioplasty is a minimally invasive and effective procedure for the treatment of thrombosed native arteriovenous fistula. Advantages of this technique are minor complication rates, cost effectiveness, high techni­cal success rate.

Introduction   Endoscopic dacryocystorhinostomy aims to establish a patent nasolacrimal fistula. Use of silicone stent is a preferred modification to achieve long term patency of neo-ostium, though it has been blamed for granulations, synechia and punctal erosion. Present study was done to  evaluate and compare the outcomes of Endoscopic dacryocystorhinostomy with and without stent.  Materials and Methods 40 patients of with chronic dacryocystitis and nasolacrimal duct blockage were selected for the study. Nasal endoscopy was done for suitability of surgical access and to detect any nasal pathology. Sac syringing was done to assess the site of blockage and Dacryoscintigraphy to confirm it. 20 patients in Group A underwent Endoscopic dacryocystorhinostomy without stent and remaining 20 in Group B with silicone stent. Success rates were determined by subjective relief from epiphora and by endoscopic visualization of rhinostomy opening, granulation tissues/ synechiae at rhinostomy site and by result of sac syringing.  Results In Group A, complete relief was obtained in 75% patients, significant relief in 10% and no relief in 15% patients thus recording overall success rate of 85%; whereas in Group B complete relief of symptom was obtained in 70% patients, significant relief in 10% and no symptom relief in 20% patients thus recording the overall success rate of 80%. Cases in Group B were also found to have persistent epiphora (17.5%), stenosis of ostium (25%), granulation (35%) and synechia (37.5%).  Conclusion Stenting does not significantly improve the success of Endoscopic dacryocystorhinostomy but is associated with more complications.
