Introduction: Given the rarity of retinoblastoma and the consequences of accidental vitrectomy in the event of misdiagnosis, reporting on clinical experience in this area is important. Objective: The aim of this study was to analyse the management and complications with a focus on local orbital recurrence and metastatic disease in 10 children vitrectomized in an undetected retinoblastoma eye. Methods: This is a retrospective descriptive case series conducted in a single-centre referral university hospital. Results: From October 1991 to June 2019, 10 patients with a vitrectomy in an unsuspected retinoblastoma eye were included in this study. The main preoperative diagnoses were unilateral inflammation with a suspected lymphoma, uveitis or toxocariasis in 5 cases, vitreous haemorrhage after trauma in 2 cases, and the last 3 were misdiagnosed with Coats disease, rhegmatogenous retinal detachment and congenital cataract. Mean age at surgery was 3 years, ranging from 14 months to 6 and a half years. Nine patients were suffering from unilateral retinoblastoma; these were enucleated and treated with 4–6 cycles of chemotherapy and/or radiation therapy. The sclerotomy sites were infiltrated with tumour cells in 3 cases. In 1 patient, the differential diagnosis of a malignant medulloepithelioma could not be excluded. One patient had bone marrow infiltration on initial presentation; all other patients are healthy without any signs of orbital recurrence or metastatic disease with a mean follow-up of 5.4 years. Conclusion: In children, intraocular tumours, including retinoblastoma and medulloepithelioma, should be ruled out before pars plana vitrectomy is performed. If no doubtless preoperative diagnosis can be established, preoperative magnetic resonance imaging is mandatory. If a vitrectomy in a retinoblastoma eye has been performed, immediate enucleation of the eye with subsequent chemotherapy and orbital radiation is effective to avoid local recurrence and systemic metastases.

The aim of this study was to verify the validity, feasibility, and the functional results, by uroflowmetry, of Tubularized proximallyincised plate technique in selected case of distal/midshaft hypospadias. Out of 120 patients scheduled to undergo TIP (or Snodgrass) procedure, 23 were selected between January 2013 and January 2016 (19.1%). This case series comprised 16 patients with distal and 7 with midshaft hypospadias. Mean age at surgery was 2.9 years. The inclusion criteria were a deep and wide glandular groove and a proximal narrow urethral plate. The procedure was carried out as described by Snodgrass but the incision of the urethral plate, including the mucosal and submucosal tissue, was made only proximally, between the original meatus and the glandular groove in no case extending to the entire length of the plate. Postoperatively a foley catheter was left in place from 4 to 7 days. Uroflowmetry was performed when the patients age ranged from 2.5 to 5.7 years (mean age 3.11 years and mean follow-up 1.8 years, body surface 2). No patient presented fistulas nor perioperative complications. At uroflowmetry, eighteen patients presented values above the 25<sup>th</sup> percentile and 5 showed a borderline flow. All patients in this group remained stable without urinary symptoms. In selected cases, the tubularized proximally-incised plate yields satisfactory cosmetic and functional results for the treatment of midshaft proximal hypospadias. A long-term follow-up study is needed for further evaluation. Patient selection is crucial for the success of this technique.

Object In this retrospective analysis the authors describe the long-term clinical results of microsurgical transdural discectomy with laminoplasty (MTDL) in patients with cervical disc herniation (CDH). Methods Thirty patients (21 males, 9 females; mean age at surgery 55 years) with CDH had surgical treatments consisting of MTDL between 1990 and 1998. All patients demonstrated signs or symptoms of cervical myelopathy and/or radiculomyelopathy. Clinical outcomes were evaluated by the Japanese Orthopaedic Association (JOA) scoring system and by recovery rate (RR). The degenerative grades of the intervertebral discs were also evaluated based on preoperative, postoperative, and final follow-up MR images. The average follow-up period was 14.1 years (range 10–22 years). Results Twenty (67%) of the 30 patients completed the follow-up in this study. The preoperative JOA scores in these patients averaged 11.8, and the postoperative scores at the final follow-up averaged 15.5 (average RR 69.6%). None of these patients required reoperation after MTDL. Although disc degeneration progressed during the follow-up period, there were no cases of clinical deterioration, recurrence of disc herniation, or postoperative kyphotic deformity. Conclusions Sufficient clinical results were obtained after the MTDL for a long-term follow-up period exceeding 10 years. The MTDL may be an option for an alternative procedure if the patients are correctly selected and the procedure is safely performed.

Purpose. Most studies about retinal detachment cover a limited follow-up period. The purpose of this research is to assess the long-term results after pars plana vitrectomy (PPV) and scleral buckle (SB) surgery in patients with rhegmatogenous retinal detachment (RRD). Methods. 155 patients with RRD are treated either with SB or PPV with a mean follow-up of more than 5 years. Retrospective analysis of patient data with RRD was performed between January 2006 and June 2008 at a tertiary eye clinic. Results. Overall primary success rate was 85.2% (PPV: 84.6%, SB: 89.5%; p=0.57). 90.5% of redetachments appeared within the first 124 days. No significant different success rate was found for vitrectomy with and without additional encircling band (p=0.09). No advantage of a supplemental encircling band in cases of preoperative inferior breaks was seen (p=0.81). Patients of SB group were treated more frequently in follow-up time because of epiretinal membrane (ERM) (SB: 15.5% versus PPV: 7.3%). No patient of the PPV group without intraoperative use of endolaser cerclage (14.7%) had any peeling surgery postoperatively. Conclusion. Redetachment rates of both methods are comparable in a clinical setting where PPV is considered a suitable method for pseudophakic patients and in complex cases and SB was performed in younger phakic patients with clearly identified retinal tears. PPV seems to show a more heterogenous pattern of complications. No advantage of a supplemental encircling band could be found in these case series of patients with primary RRD. No relevant long-term risk of redetachment was seen after SB.

The benefits of percutaneous dilational tracheostomy (PDT) placement have been well documented in patients requiring prolonged mechanical ventilation. However, the data regarding the benefit of PDT in coronavirus-2019 (COVID-19) patients are scarce. The objective of this study is to evaluate the outcomes of a cohort of 37 patients who underwent tracheostomy as part of their COVID-19 care. Retrospective data from a series for 37 patients undergoing tracheostomy was collected using chart review. Primary outcomes included 30 and 60 day mortality, weaning rate, and decannulation rate. Secondary outcomes collected included admission demographics, comorbidities, and procedural information. Thirty-seven (37) patients requiring prolonged mechanical ventilation due to COVID-19. Of these 37 patients, 35 were alive 60 days post-PDT placement, 33 have been weaned from mechanical ventilation and 18 have been decannulated. The low mortality and high decannulation rates in this cohort in is a promising development in the care of critically ill COVID-19 patients. Of note, all participating physicians underwent routine polymerase chain reaction (PCR) testing for infection with the severe acute respiratory syndrome coronavirus-2 virus and no physician contracted COVID-19 as a result of their involvement. Overall, this case series describes the modified PDT technique used by our team and discusses the feasibility and potential benefit to PDT placement in COVID-19 patients requiring long-term mechanical ventilation.

Objective Congenital airway stenosis secondary to absent tracheal or bronchial rings is a rare congenital anomaly that is difficult to manage both clinically and surgically. This typically manifests as severe segmental tracheomalacia, and only isolated cases with short-term follow-up have been previously described. We aim to describe a series of children with absent tracheal or bronchial rings who underwent surgical management and had long-term follow-up. Study Design Case series with chart review. Setting Tertiary care pediatric hospital. Methods Patients with absent tracheal or bronchial rings from 2002 to 2016. Electronic and paper medical records were queried to obtain demographics, age at diagnosis and surgery, pre- and postoperative symptoms, location of absent rings, procedure performed, length of follow-up, and adjunctive procedures performed. Results Nine subjects were identified who underwent slide tracheoplasty for correction of congenital absent tracheal or bronchial rings. Age at diagnosis ranged from 10 days to 5 years of age (median, 4 weeks). Age at surgery ranged from 3 weeks to 5 years of age (median, 5 weeks). Six out of 9 subjects were extubated on postoperative day 1. Only 1 subject required additional intervention, which included balloon dilation, tracheobronchial stenting, and aortopexy to alleviate the obstruction. Mean follow-up time was 5.89 years. Conclusions This is the largest series of children with absent tracheal rings who underwent slide tracheoplasty with long-term follow-up presented to date. Slide tracheoplasty is an effective surgical intervention for the treatment of absent tracheal or bronchial rings in infants and young children.

Sutureless Vitrectomy

Purpose: The purpose of this case series is to evaluate the long-term visual outcomes of patients undergoing epiretinal membrane (ERM) removal combined with internal limiting membrane (ILM) peeling via sutureless vitrectomy. Methods: A retrospective review was conducted of 45 patients (45 eyes) with ERMs treated with 25-gauge pars plana vitrectomy (PPV) from 2010 to 2011. Data assessed included baseline characteristics, preoperative and postoperative best-corrected visual acuity (BCVA), ERM recurrence rate during follow-up, and complications arising during follow-up. Results: PPV resulted in a statistically significant improvement in BCVA (20/61 preoperatively, 20/41 1 year postoperatively, and 20/45 at the end of follow-up). Mean duration of follow-up was 66.3 months (range, 26-89). Forty-one of 45 (91%) eyes had improved or stable vision, while 4/45 (8.9%) had worse vision. ERMs recurred in 12/45 eyes (26.7%), of which 1/45 (2.2%) required reoperation. The remaining 11 recurrent ERMs were documented as visually insignificant. Mean time to ERM recurrence was 29.3 months (range, 4-72). Conclusions: In one of the longest mean follow-up studies to date, small-gauge PPV for ERM and ILM removal results in statistically significant and stable long-term visual improvement. Despite ILM removal, ERMs did recur in a substantial proportion of patients, though the vast majority were not visually significant.

Background: We investigated the long-term clinical results of percutaneous transluminal angioplasty (PTA) in patients with peripheral arterial occlusive disease (PAOD) and the influence of different parameters on the primary success rate, the rate of complications and the long-term outcome. Patients and methods: We reviewed clinical and hemodynamic follow-up data of 166 consecutive patients treated with PTA in 1987 in our department. Results: PTA improved the clinical situation in 79.4% of patients with iliac lesions and in 88.3% of patients with femoro-popliteal lesions. The clinical stage and ankle brachial index (ABI) post-interventional could be improved significantly (each P < 0,001), the same results were observed at the end of follow-up (each P < 0,001). Major complications occurred in 11 patients (6.6%). The rate of primary clinical long-term success for suprainguinal lesions was 55% and 38% after 5 and 10 years (femoro-popliteal 44% and 33%), respectively, the corresponding data for secondary clinical long-term success were 63% and 56% (60% and 55%). Older age (P = 0,017) and lower ABI pre-interventional (P = 0,019) significantly deteriorated primary clinical long-term success for suprainguinal lesions, while no factor could be identified influencing the outcome of femoro-popliteal lesions significantly. Conclusion: Besides an acceptable success rate with a low rate of severe complications, our results demonstrate favourable long-term clinical results of PTA in patients with PAOD.

OBJECTIVEFew studies describe long-term functional outcomes of pediatric patients who have undergone lumbar microdiscectomy (LMD) because of the rarity of pediatric disc herniation and the short follow-up periods. The authors analyzed risk factors, clinical presentation, complications, and functional outcomes of a single-institution series of LMD patients over a 19-year period.METHODSA retrospective case series was conducted of pediatric LMD patients at a large pediatric academic hospital from 1998 to 2017. The authors examined premorbid risk factors, clinical presentation, physical examination findings, type and duration of conservative management, indications for surgical intervention, complications, and postoperative outcomes.RESULTSOver the 19-year study period, 199 patients underwent LMD at the authors’ institution. The mean age at presentation was 16.0 years (range 12–18 years), and 55.8% were female. Of these patients, 70.9% participated in competitive sports, and among those who did not play sports, 65.0% had a body mass index greater than 25 kg/m2. Prior to surgery, conservative management had failed in 98.0% of the patients. Only 3 patients (1.5%) presented with cauda equina syndrome requiring emergent microdiscectomy. Complications included 4 cases of postoperative CSF leak (2.0%), 1 case of a noted intraoperative CSF leak, and 3 cases of wound infection (1.5%). At the first postoperative follow-up appointment, minimal or no pain was reported by 93.3% of patients. The mean time to return to sports was 9.8 weeks. During a mean follow-up duration of 8.2 years, 72.9% of patients did not present again after routine postoperative appointments. The total risk of reoperation was a rate of 7.5% (3.5% of patients underwent reoperation for the same level; 4.5% underwent adjacent-level decompression, and one patient [0.5%] ultimately underwent a fusion).CONCLUSIONSMicrodiscectomy is a safe and effective treatment for long-term relief of pain and return to daily activities among pediatric patients with symptomatic lumbar disc disease in whom conservative management has failed.
