Surgery for Bronchiectasis: Experience and Outcomes atStarship Children's Hospital, Auckland, New Zealand.

Surgical management for bronchiectasis is uncommon. This study reviewed the experience of bronchiectasis surgery and subsequent outcomes at a tertiary paediatric centre over a 20 year period. Retrospective audit of children aged < 18 years who underwent bronchiectasis surgery at Starship Children'sHospital between 2001 and 2021. Cases were identified from clinical coding, with demographics, pre-operative investigations and outcomes obtained from clinical records. Nineteen children (11 females, 42% Pasifika, 26% Māori and 26% New Zealand European) were included. Mean age of bronchiectasis diagnosis was 6.3 years (range 2.1-13.9 years) and mean age of surgery was 8.5 years (range 2.6-15.9 years). Indications for surgery included localised bronchiectasis (n = 7), main burden of multilobar disease in one lobe (n = 5) and persistent lobar collapse (n = 3). Pre-operative investigations included chest computerised tomography scan (68%), bronchoscopy (37%) and overnight oximetry (42%). One child underwent documented pre-operative clinical optimisation. For children with bronchiectasis < 5 years (n = 11), 81% demonstrated improved symptoms, 9% were unchanged and 9% deteriorated. All children with bronchiectasis > 5 years had symptomatic improvement. The mean number of daily symptoms decreased by 2.4 (p < 0.0001). Lobectomy resulted in significant symptomatic improvement in 89% of children. However, pre-operative work-up was variable. The study highlights the importance of establishing a protocol for identification of children with bronchiectasis who would benefit from surgery and developing a consistent preparatory approach to ensure optimal and equitable outcomes.

Posterior Vault Distraction Osteogenesis for Craniosynostosis-Surgical Outcomes Over 12 Years.

Posterior vault distraction osteogenesis (PVDO) allows significant increase in intracranial volume but is associated with complications including cerebrospinal fluid (CSF) leaks, infection and device failure. The authors outline their outcomes over 12 years and the impact of PVDO on pre-existing Chiari malformation type 1 (CM). Retrospective review of all PVDOs in our unit over a period of 12 years from 2011 to 2023. Results: 51 patients. The mean age of surgery 9 months. The mean length of follow-up 72 months. 82% no complications, 12% dural tear with 2% CSF leak; 4% infection, 2% device failure, 10% blood transfusion. CM in 20% of patients-all are multisuture with 90% lambdoid synostosis involvement. CM is unchanged in the majority of patients post-PVDO. PVDO safe and effective with no re-do posterior vault expansions over 12 years. CM does not tend to resolve after PVDO and high-risk groups include multisuture and Crouzons.

Neonatal Gastrointestinal Perforations: A 4-year Experience in a Single Centre.

Gastrointestinal perforation (GIP) during the neonatal period is still a significant problem despite improved neonatal care. The study aimed to report on incidence, management, morbidity and mortality. Records of neonates with GIPs between October 2018 and November 2022 were retrospectively analysed. There were 47 patients, 22 (46.8%) males and 25 (53.2%) females. The incidence of neonatal GIP was 0.39% amongst all newborns treated in the neonatal intensive care unit. The mean gestational age was 30.4 ± 4.5 (23-38) weeks, and the mean birth weight was 1493.08 ± 753 (580-2940) g. Of 47 neonates, 5 (10.6%) were full term and 42 (89.4%) were preterm. The mean age of surgery was 12.25 ± 9.89 (0-41) days. A laparotomy was performed in 43 (91.4%) of 47 neonates, while seven of the patients underwent surgical intervention after decompression by percutaneous drainage. Four patients were managed with peritoneal drainage alone due to poor general condition. The pathologies unrelated to necrotising enterocolitis (NEC) were the most common cause of GIPs (55.3%) and included spontaneous intestinal perforation (n = 18), stomach perforation (n = 4), segmental volvulus (n = 2), acute mesenteric ischaemia (n = 1) and meconium peritonitis (n = 1). Overall survival was 55.4%. GIPs are one of the most significant causes of mortality in newborns. The most common cause of perforations is non-NEC entities and can be seen in the entire intestinal system from the stomach to the colon. Surgical exploration is still the primary management model.

Distraction osteogenesis in craniosynosotosis: technical note

Introduction: Craniosynostosis is a group of diseases whose main characteristic is the premature fusion of one or more cranial sutures. They can be subdivided into non-syndromic and syndromic. The posterior vault distraction osteogenesis (PVDO) has become the standard procedure for managing the intracranial hypertension of these patients. The objective of this paper is to report the experience of the Sobrapar Hospital (Campinas, Brazil) in treating and following up on syndromic craniosynostosis patients subjected to PVDO and highlight the lessons learned throughout this process. Methods: The medical records of the patients treated at the Sobrapar Hospital between 2013 and 2023 were reviewed. Results: The total of patients initially candidates to PVDO was 79, and 75 of them proceeded to the surgery. The mean age of surgery was 8,16 months old (ranging from 4 months to 12 years old). The length of stay ranged from 2 to 14 days, with a mean of 3,29 days. The distraction achieved ranged from 13 mm to 30 mm, with a mean distance of 23 mm. The postoperative complications were mostly cutaneous. CSF leak occurred in 3 patients. Conclusion: PVDO provides a progressive formation of a vascularized bone, its intracranial volume expansion is greater than the FOA, increasing the posterior fossa’s size (even when the craniotomy is supratorcular) and it improves Chiari’s symptoms, even when the radiologic abnormalities are not necessarily solved. A specialized and multidisciplinary team is essential to improving the success rates of the surgery.

Risk of visual axis opacification in infants with and without primary IOL implantation after congenital cataract surgery performed during the first 4 months of age

PurposeThe study evaluates the rate of postoperative formation of a pupillary membrane (PM) and posterior visual axis opacification (PVAO) in infants with and without primary IOL implantation during the first 4 months of infancy.MethodsMedical records for 144 eyes (101 infants) operated between 2005 and 2014 were evaluated. A posterior capsulectomy and anterior vitrectomy were performed. Primary IOL implantation was performed in 68 eyes, while 76 eyes were left aphakic. There were 16 bilateral cases in the pseudophakic group and 27 in the aphakic group. The follow-up period was 54.3 ± 21.05 months and 49.1 ± 18.60 months, respectively. Fisher’s exact test was used for statistical analysis. The two-sample t-test with equal variance was used to compare surgery age, follow-up period and time intervals of complications.ResultsThe mean age of surgery was 2.1 ± 0.85 months in the pseudophakic and 2.2 ± 1.01 months in the aphakic group. PM was diagnosed in 40% pseudophakic and 7% aphakic eyes. A second surgery for PVAO was performed in 72% pseudophakic and 16% aphakic eyes. Both were significantly higher in the pseudophakic group. In the pseudophakic group, the number of PVAO was significantly higher in infants operated before 8 weeks of age compared to surgery age 9–16 weeks. The frequency of PM was not age-dependent.ConclusionAlthough it remains feasible to implant an IOL during the primary surgery, even in very young infants, there should always be solid arguments for this decision since it puts the child at higher risk of repeated surgeries under general anaesthesia.

Amputation vs Reconstruction in Type IV Tibial Hemimelia: Functional Outcomes and Description of a Novel Surgical Technique.

The management of tibial hemimelia can be complex and involve either amputation or reconstruction. The decision made carries significant implications on patients and their families. This is a case series in the management of Type IV tibial hemimelia with a description of a novel surgical technique in the reconstructive arm of the pathway. The study included four patients with bilateral tibial hemimelia have an amputation in one limb and reconstructive surgery on the other. The reconstruction involved a supratalar double osteotomy of the tibia and fibula, followed by a staged hindfoot osteotomy using a circular ring fixator. Functional outcomes are reported using the Special Interest Group in Amputee Medicine (SIGAM) and the short form 12 (SF-12) methods. The mean age of patients in our cohort is 14 years (3-27 years) with mean age of surgery at 3 years. One case had an amputation following initial reconstructive surgery due to psychological distress and regressive behaviour. SIGAM functional outcome scores of F were recorded in three of four cases, with one patient performing at level B. On the reconstructive side, two of three patients reported a mean physical short form 12 (SF-12) score of 56.7 and a mental SF-12 score of 55.7. One patient reported a physical SF-12 score of 28.5 and a mental SF-12 score of 30.3. A reconstructive option provides a satisfactory functional outcome, comparable to the population mean, in the majority of patients in our cohort. A staged supratalar double osteotomy followed later by a hindfoot osteotomy is effective in centralising the ankle and creates a plantigrade weight-bearing platform for ambulation in patients with Type IV tibial hemimelia.

DÖRT YAŞINDAN BÜYÜK GELİŞİMSEL KALÇA DİSPLAZİSİ OLAN HASTALARDA, TEK AŞAMALI AÇIK REDÜKSİYON, FEMORAL KISALMA VE SALTER OSTEOTOMİSİ’NİN RADYOLOJİK SONUÇLARINI, İLK AMELİYAT YAŞI NASIL ETKİLER ?

OBJECTIVE: One of the most controversial issues in pediatric orthopedics is Developmental dysplasia of the hip (DDH). The timing of diagnosis and treatment are is the main goal to treat this condition successfully. Neglected cases that may remain undiagnosed until advancing age are still seen especially in developing countries. Delayed diagnosis and treatment with advancing age leads to more extensive surgery and cause low satisfactory rates. The aim of this study is to evaluate the effect of patients’ age on the results of single-stage treatment of Developmental Dysplasia of the Hip.MATERIAL AND METHODS: 23 patients (34 hips) treated in our hospital between 2004 and 2010 were included in the study. Single-stage treatment including open reduction, femoral shortening, and Salter’s innominate osteotomy was applied to patients whose mean age of surgery was 7.5 years. Radiological results were evaluated in terms of improvement in the acetabular index, in the acetabular angle and according to Severin’s classification, and Bucholz and Ogden’s avascular necrosis (AVN) classification at the final follow-up.RESULTS: The average follow-up period was 60 (range: 24 - 84) months. While the acetabular index was 39.7°±1.4° (range: 25°- 52°) preoperatively, it was measured as 21.8°±1.8° postoperatively. The mean amount of improvement in the acetabular angle was 17.9°±0.8°. According to Bucholz and Ogden’s classification, one patient (2.9%) had Type 1 AVN and one patient (2.9%) had Type 3 AVN. Radiologically, the success rate (85.7%) was significantly higher in children aged 8 years and younger (p = 0.008).CONCLUSIONS: According to the improvement in the acetabular index and Severin's radiological classification, successful results are obtained after a single-step treatment of DDH, which is treated in the 4-8 age range. However, the radiological results of children older than 8 years are worse than those under 8 years old.

Laparoscopic cyst enucleation is a promising technique for treatment of gastrointestinal tract duplications in children

BackgroundLaparoscopic cyst enucleation has its advantages and limitations in treatment of gastrointestinal tract (GIT) duplications. It allows to avoid bowel resection in such locations as ileocecal valve. We introduced laparoscopic cyst enucleation with further bowel plasty using cyst muscle layer and without monopolar coagulation, for cyst dissection we used straight scissors. Materials and methodsOur study included 20 children with GIT duplications, who underwent cyst enucleation from 2018 to 2021. Laparoscopy was performed in all cases with various cyst locations (stomach – 2, duodenum – 3, small bowel – 14, ileocecal area – 1). Mean age of surgery was 40 ± 35,3 days (min 6 days, max 150 days). ResultsMean operation time was 84,4 ± 27,35 min (min – 40 min, max – 160 min). We had no intraoperative complications. All patients received parenteral feeding for 3–5 days after the operation. Postoperative complications occurred in 3 cases: bowel perforation which required enterostomy (10%) and bowel volvulus required resection (5%). To our opinion, perforations occurred due to monopolar coagulation used for cyst enucleation in these children. No complications were observed in patients who underwent enucleation by straight scissors. Mean postoperative hospital stay was 15.6 ± 10.48 days (min – 4 days, max – 58 days). We observed neither stenosis nor any other complications in the long-term follow-up. ConclusionsLaparoscopic cyst enucleation is a feasible and safe approach for GIT duplications. It allows to avoid bowel resection, and the use of straight scissors instead of monopolar coagulation provides less postoperative complications such as perforation. The Level of evidenceIII.

Tethered cord secondary to focal nondisjunction of the primary neural tube: experience from a Singapore children’s hospital

Purpose Tethered cord due to focal nondisjunction of primary neuralisation (FNPN) is a rare form of spinal dysraphism. We present our institutional experience in managing children diagnosed with FNPN. Materials and methods This is a single institution, retrospective study approved by the hospital ethics board. Patients below 18 years of age diagnosed with CDS, LDM or their mixed lesions, and subsequently underwent intervention by the Neurosurgical Service, KK Women’s and Children’s Hospital, are included. Results From 2001 to 2021, 16 FNPN patients (50% males) were recruited. Eight of them had CDS (50.0%), seven had LDM (43.8%), and one patient had a mixed CDS and LDM lesion (6.2%). The average duration of follow up was 5.7 years and the mean age of surgery was 6 months old. Thirteen patients underwent prophylactic intent surgery (81.2%) and three had therapeutic intent surgery (18.8%). All patients did not have new neurological deficit or required repeat surgery for cord retethering. We observed that detethering surgery performed at or less than three months old was associated with having a wound infection (p = .022). Conclusions Our study reports that early recognition and timely intervention are mainstays of management for FNPN. We advocate a multi-disciplinary approach for good outcomes.

Posterior quadrant epilepsy surgery: case series of a South American hospital

BackgroundPosterior quadrant epilepsy (PCE) is a type of focal epilepsy that originates in the parietal lobe, occipital lobe, and the parietal-occipital border of the temporal lobe, or in any combination of these regions. PCE has a low incidence, but it can cause a great burden in disability-adjusted life years. In this retrospective cohort, patients of all ages with a diagnosis of PCE between 2006 and 2019 were evaluated in a referral center in Bogotá, Colombia. A descriptive analysis of demographic data, clinical history, imaging findings, type of surgery, histopathological diagnosis, outcome, and follow-up was performed using the Engel scale.MethodsThis study included refractory PCE patients of all ages who were evaluated by the epilepsy surgery group of the Hospital Universitario San Ignacio from 2006 to 2019. Clinical, imaging and surgical variables were obtained from the medical records and analyzed. ResultsThirteen patients were included in the study, including 8 males and 5 females. The mean age of diagnosis was 8.8 years, while the mean age of surgery was 25 years. The most frequent clinical finding was intellectual disability. The most common findings on magnetic resonance imaging were encephalomalacia and gliosis. In 61.5% of the patients, the lateralization of video-EEG matched with brain magnetic resonance imaging alteration. The most frequent types of surgery performed were lobectomies, lesionectomies and cortical resections. Seizure-freedom was achieved in approximately one third of the patients; however, more than half of the patients were free of disabling seizures or had significant improvement after surgery.ConclusionsPCE surgery is scarcely performed worldwide, therefore the effectiveness and outcomes are quite variable in the reported literature. In this study, we show that patients with PCE can obtain great benefits in terms of reduction of seizures with a low risk of surgical complications, encouraging the use of this type of procedure in carefully selected patients.

The Effect of Pre-Incision Urethral Plate Width and Glanular Width on the Outcome of Tubularized Incised Urethral plate repair surgery in Distal Penile Hypospadias, A prospective study.

To determine hypospadias repair's cosmetic and functional outcome concerning the urethral plate width and glanular width. A prospective study including 38 patients. The urethral plate width (UPW) was measured preoperatively. The cosmetic outcome was evaluated by hypospadias objective penile evaluation [HOPE] score, and the urinary stream evaluated functional outcome. We included boys with distal penile hypospadias and excluded recurrent cases with severe chordee. All patients were operated on by Snodgrass tubularized incised plate repair (TIP); they were followed up for one year. Success was defined as slit-shaped meatus at the tip of the glans without fistula. The mean age of surgery was 4.5 ± 2.1 years. UPW was < 8 mm in 24 patients (63.2 %) (Group A), while 14 patients (36.8 % ) (Group B) had a UPW ≥ 8 mm. Overall, the mean ± SD of UPW was 4.84 ± 1.29 mm. The mean ± SD of GW was 9.52 ± 1.56 mm. Overall success was documented in 35/38 patients (92.1 %). No significant relation was founded between the complications and UPW of the patients (p-value = 0.7). Overall, the mean ± SD HOPE score was 39.1 ± 8.83. A significant relation was found between the cosmetic outcome of the two groups and the HOPE score (p-value = 0.02). The pre-incision urethral plate width and glanular width were not correlated with the TIP outcome. A better HOPE score is associated with a wide urethral plate.

Anterior Vertebral Body Tethering for Treatment of Idiopathic Scoliosis in the Skeletally Immature: Results of 112 Cases.

Prospective case series. Determine the efficacy of anterior vertebral body tethering (AVBT) in skeletally immature patients. The value of AVBT is currently unclear given the paucity of available data. Consecutive skeletally immature patients with idiopathic scoliosis were treated with AVBT between 2012 and 2018 by one of two surgeons working at two independent centers and followed up for >2 years. Data were collected prospectively and supplemented retrospectively where necessary. Outcomes were measured preoperatively, at first erect radiograph (FE), 1-year postoperatively and at most recent follow up (FU). One hundred twelve patients underwent 116 primary tethering procedures (108 thoracic and eight lumbar tethers). Four patients had primary tethering of both lumbar and thoracic curves. At surgery mean age was 12.7 ± 1.4 years (8.2-16.7) and Risser 0.5 ± 0.9 (0-3). Follow up was mean 37 ± 9 months (15-64). Preoperative mean coronal Cobb angle of the 130 tethered curves was 50.8° ± 10.2 (31-81) and corrected significantly to 26.6° ± 10.1 (-3-61) at FE radiograph (P < 0.001). Further significant improvement was seen from FE to 1-year, to mean 23.1° ± 12.4 (-37-57) (P < 0.001). There was a small but significant increase between 1-year and FU to 25.7° ± 16.3 (-32-58) (P < 0.001), which appeared to reflect tether breakage. Untethered minor curves were corrected from 31.0° ± 9.5 (3-57) to 20.3° ± 10.3 (0-52) at FU (P < 0.001). Rib hump was corrected from 14.1 ± 4.8 (0-26) to 8.8° ± 5.4 (0-22) at FU (P < 0.01). Twenty-five patients (22%) had 28 complications. Fifteen patients (13%) requiring 18 revision operations including six completed and one awaited fusions. AVBT of immature cases is associated with satisfactory deformity correction in the majority of cases. However, complication and revision rates suggest the need for improved implants and patient selection. Long-term follow-up remains crucial to establish the true efficacy of this procedure.Level of Evidence: 3.

Risk Factors of Urethro-cutaneous Fistula Development in Hypospadias Surgery

Urethrocutaneous fistula development is the most common complication found hypospadias surgery. Several factors associated with the incidence of fistulas are the age at the time the surgery. The type of hypospadias, the degree of chordae, the operative technique applied and catheter type. This study aimed to determine the risk factors associated with the urethro-cutaneous fistula development in hypospadias surgery. The results showed that from 310 hypospadias patients undergoing urethroplasty, urethra cutaneous fistula development occurred among 105 patients (30.6%) with a mean age of surgery 10.89+6.27 years. Hypospadias type has a significant difference with the incidence of urethro-cutaneous fistula development (p = 0.027). Age (p = 0.615), degree of chordae (P=0.805), operative technique (P=0.901) and catheter type (P=691) do not have a significant impact to urethro-cutaneous fistula development. It can be concluded that operative urethroplasty has a risk of urethra-cutaneous fistula that associated with hypospadias type.

The congenital sternoclavicular sinus: a single-institution retrospective study of 88 patients

BackgroundSinus near the sternoclavicular joint was considered as a rare congenital neck abnormality. Though it was reported as a dermoid sinus in some literatures, the embryological origin of the sinus was unclear. This study aimed at reviewing the clinical and histological characteristics and analyzing the possible embryological origin of this malformation in children.MethodsThe medical records of all patients with congenital sternoclavicular sinus who underwent surgical resection between March 2018 through June 2020 were reviewed retrospectively. The clinical presentations, complications, histological examination, and treatment were analyzed.ResultsOf the 88 patients with congenital sternoclavicular sinus included, the mean age of surgery was 2.73 ± 1.71 years old. The sinuses occurred on the left side in 73 (83.0%) cases. Sixty-three patients experienced sinus infection and 44 patients underwent incision and drainage before excision. All patients received surgical resection with one patient who recurred after surgery. Histopathological examination showed that the sinuses were lined by squamous epithelium in most patients. However, ciliated epithelium was observed in one patient and salivary glands were detected in two patients.ConclusionsThe congenital sternoclavicular sinus should be excised promptly to prevent recurrent infection. According to the ciliated epithelium and salivary gland were found in the wall of sinus, it should be viewed as the skin side remnant of the fourth branchial cleft rather than a dermoid cyst/sinus.

Episcleral hemangioma distribution patterns could be an indicator of trabeculotomy prognosis in young SWS patients.

To explore the relationships between episcleral hemangioma distribution patterns and trabeculotomy prognosis in young Sturge-Weber syndrome (SWS) patients. Sturge-Weber syndrome-induced glaucoma patients less than 4years of age who underwent trabeculotomy in our Ophthalmology Department from February 2016 to June 2017 were included. Every patient could be divided into simple episcleral vascular abnormal network (SEVAN) or multiple episcleral vascular abnormal network (MEVAN) groups according to their episcleral hemangioma patterns. The intraocular pressure (IOP) was recorded during follow-up until the last visit. Fifty eyes (forty-six patients) of SWS were included. Mean age of surgery was 12.6±15.1months (range 1-47months). Twenty-six eyes were in the SEVAN group, while 24 eyes were in the MEVAN group. There were no significant differences between the two groups in demographic data before surgery (p>0.05). IOPs at 12months (p=0.013) and 24months (p=0.002) were significantly different between the two groups. At the 24-month follow-up, the cumulative proportions of trabeculotomy success in the SEVAN and MEVAN groups were 89.7% and 36.0%, respectively. Patients with MEVAN and larger preoperative corneal diameter (per 0.5mm) were more likely to experience failed trabeculotomy (hazards ratio [HR], 7.997 [95% CI, 1.640-38.996], p=0.010; 1.853 [95% CI, 1.128-3.042], p=0.015). Hemangiomas exhibited different distribution patterns between SEVAN and MEVAN. Trabeculotomy had a poorer prognosis in young SWS patients with MEVAN than in those with SEVAN. In addition to anterior chamber angle anomalies, vascular factors may contribute to the aetiology of SWS early-onset glaucoma.

Urodynamic changes of spinal lipoma in children before and after surgery

To study the urodynamic changes of various types of spinal lipoma in children before and after surgery. Twenty patients with spinal lipoma treated in our hospital were retrospectively analyzed. According to Pang's classification, they were divided into Dorsal, Transitional, Chaotic and Terminal types. Urodynamic changes before and after surgery were compared. Dorsal type: 1 case, the age of surgery was 14 months, low-risk bladder before and after operation; Transitional type: 4 cases, the mean age of surgery was 32.3 months, of which 3 cases were low-risk bladder and 1 case was high-risk bladder before operation, all without change in urodynamics after operation; Chaotic type: 10 cases, the mean age of surgery was 13.2 months, 8 cases were low-risk bladder, 1 was high-risk bladder and 1 was middle-risk bladder before operation. After operation, 4 of 8 low-risk bladders deteriorated to medium-risk bladder. The high-risk bladder improved to low-risk bladder, and the middle-risk bladder remained unchanged. Terminal type: 5 cases, the mean age of surgery was 54.2 months, 2 cases were high-risk bladder and 3 cases were low-risk bladder before operation, 1 case was improved to low-risk bladder, and the other 4 cases remained unchanged. Dorsal and Transitional types occur in the primary neurulation, and there is no significant change in urodynamics before and after surgery. Chaotic type occurs between the primary and secondary neurulation. Lipomas are usually large and mixed with conus medullaris and nerve roots. Even with early surgical treatment, there is still a high probability of deterioration of lower urinary tract function. Terminal type occurs in the secondary neurulation. It is often found late and clinical symptoms often occur before the operation. Urodynamic results could be improved after the operation.

Orbital decompression surgery for the treatment of Graves' ophthalmopathy: comparison of different techniques and long-term results.

To evaluate the long-term results of different orbital decompression techniques performed in patients with Graves' ophthalmopathy (GO). Totally 170 cases with GO underwent orbital decompression between 1994 and 2014. Patients were divided into 4 groups as medial-inferior, medial-lateral (balanced), medial-lateral-inferior, and lateral only according to the applied surgical technique. Surgical indications, regression degrees on Hertel exophthalmometer, new-onset diplopia in the primary gaze and new-onset gaze-evoked diplopia after surgery and visual acuity in cases with dysthyroid optic neuropathy (DON) were compared between different surgical techniques. The study included 248 eyes of 149 patients. The mean age for surgery was 42.3±13.2y. DON was the surgical indication in 36.6% of cases, and three-wall decompression was the most preferred technique in these cases. All types of surgery significantly decrease the Hertel values (P<0.005). Balanced medial-lateral, and only lateral wall decompression caused the lowest rate of postoperative new-onset diplopia in primary gaze. The improvement of visual acuity in patients with DON did not significantly differ between the groups (P=0.181). The study show that orbital decompression surgery has safe and effective long term results for functional and cosmetic rehabilitation of GO. It significantly reduces Hertel measurements in disfiguring proptosis and improves visual functions especially in DON cases.

Intraocular lens implantation in children with unilateral congenital cataract in the first 4 years of life.

To describe the outcome of phacoaspiration with intraocular lens implantation in children with unilateral congenital cataract in the first 4 years of life. A retrospective chart review of children with visually significant unilateral congenital cataract presenting in the first 4 years of life was done. Children with a minimum postsurgical follow-up of 1 year were included. Outcome measures were mean spherical equivalent, visual axis clarity, visual acuity and complications till the last follow-up. Ninety-three children met the inclusion criteria. The mean age of surgery was 13.23 ± 11.89 months and the mean follow-up period was 24.37 ± 17.35 months. Nearly 40% of children presented during their first year of life. No difference was noted between the subgroups in terms of age ( p = 0.310), sex ( p = 0.475) or laterality ( p = 0.349). Surgical membranectomy was performed in 22 eyes (23.6%) after an average period of 4.85 ± 2.58 months after surgery. One eye underwent piggy back intraocular lens and four eyes underwent intraocular lens exchange after a mean duration of 50 months (range 40-60 months). The mean visual acuity was 0.79 ± 0.11 (log MAR chart). A total of 60.7% of these children ( n = 31) achieved best corrected visual acuity or 20/80 or better. The results of our study suggest that primary intraocular lens implantation in children with unilateral congenital cataract gives good structural and functional results. Besides a meticulous surgery, visual outcome is affected by the time of presentation and postoperative compliance to amblyopia therapy.

EVALUATION OUTCOMES OF THE LAPAROSCOPIC RETROPERITONEAL NEPHRECTOMY FOR BENIGN NONFUNCTIONING KIDNEYS

Purpose: To assess results of retroperitoneoscopy nephrectomy for benign non-function kidneys from June 2013 to June 2017 at Quang Tri General Hospital. Materials and Methods: The study comprised 43 patients who underwent retroperitoneoscopic nephrectomy during a 4 years period beginning from June 2013. Results: Mean age of surgery was 52.6 years (28-72 years). 23 males and 20 females. 25 patients underwent left nephrectomy; 18 underwent right nephrectomy. Retroperitoneoscopic nephrectomy were completed successfully in 38 patients (88.4%). There was 5 patients required conversion to open surgery (11.6%), all cases by poor progression. The mean operating time was 112.7 minutes (range 70 to 210), mean blood loss was 45.7 ml (range 15 to 170 ml), and mean post-operation hospital stay was 4.3 days (range 3 to 9). A total of 21.1% complications (8/38 cases), no severe complications occurred. No re-intervention was needed. No case was mortality. The indications for surgery included hydronephrosis in 19/38 cases (50.0%), atrophic kidney in 13/38 cases (34.2%) and multicystic kidney in 6/38 cases (15.8%). Conclusions: Retroperitoneoscopic nephrectomy can be performed safely and successfully with obvious advantages for benign nonfunctioning kidneys regardless of the etiology or pathogenesis.

Long-term Outcomes of Primary Intraocular Lens Implantation in Patients Aged 7 to 24 Months

To report long-term outcomes of primary intraocular lens (IOL) placement in patients aged 7 to 24 months. This was a retrospective study of 27 consecutive patients (28 eyes) aged 7 to 24 months who underwent cataract surgery with primary IOL placement. Average follow-up was 62.7 ± 41.7 months and the mean age of surgery was 14.4 ± 5.6 months. Mean final visual acuity was 1.02 ± 0.72 logMAR (20/209). Adverse events occurred in 7 eyes (25%) and included visual axis opacification in 6 eyes and pupillary block glaucoma in 1 eye. Seven patients (25.9%) required additional intraocular surgery. Strabismus was present in 19 patients (70.4%). Better stereopsis was correlated with better final acuity. Cataract surgery with IOL placement in patients aged 7 to 24 months is associated with few complications. Visual axis opacification is the most frequent adverse event.
