RESUMO

OBJECTIVE: To compare the risk of recurrent epistaxis between children treated with silver nitrate (SN) in the office or electrocautery (EC) in the operating room (OR). METHODS: Patients aged 2-18 diagnosed with epistaxis (ICD R04.0) in 2018 and treated with SN or EC were retrospectively reviewed. Epistaxis laterality, history of nasal trauma, and personal or family history of a bleeding disorder were recorded. Patients with prior cautery or epistaxis secondary to a procedure were excluded. Recurrence was defined as initial encounter after cautery with documented epistaxis. Patients were followed up into 2022 to track onset of recurrence. Time to recurrence between SN and EC was compared with hazard curves with predictors for recurrence analyzed via Cox's proportional hazard regression. RESULTS: Among 291 patients cauterized for epistaxis, 62 % (n = 181) received SN compared to 38 % (n = 110) who underwent EC. There was significantly higher risk of recurrence when treated with SN compared to EC (Hazard ratio 2.45, 95 % CI: 1.57-3.82, P < 0.0001). Median time to recurrence was not statistically different between techniques (6.39 months (SN) (IQR: 2.33, 14.82) vs. 4.11 months (EC) (IQR: 1.18, 20.86), P = 0.4154). Complication rates were low for both groups (1.16 % (SN) vs. 0 % (EC), P > 0.05). CONCLUSION: Among patients with epistaxis, risk of recurrence is significantly higher in those cauterized with SN compared to EC. Time to recurrence is not significantly different between cautery techniques.

RESUMO

Approaches to the treatment of infant hydrocephalus vary among centers. Standard shunting carries a significant infection rate, an unpredictable time-to-failure, and the life-long risk of recurrent failures. Combined choroid plexus cauterization (CPC) and endoscopic third ventriculostomy (ETV) have been increasingly employed over the past decade as an alternative approach in an attempt to avoid shunt dependency. We performed a systematic review and meta-analysis to explore the reported morbidity associated with ETV/CPC and its rate of success reported for specific etiologies of infant hydrocephalus. The protocol of this study was registered with the International prospective register of Systematic Reviews (PROSPERO) with the following registration number: CRD 42022343898. The study utilized four databases of medical literature to perform a systematic search following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Several parameters were extracted from the included studies including authors, publication year, region, study design, sample size, mean age, success rate, complication rate, reported complications, hydrocephalus etiology, median time-to-failure, secondary management after failure, and mean follow-up time. The outcomes of interest, success, and complication rates were pooled using 95% confidence intervals (CI) and a random effects model. Heterogeneity was assessed using the I2 test. Twenty-eight studies met the inclusion criteria from an initial search result of 472 studies. The study included 1938 infants (1918 of which were included in the meta-analysis). The overall success rate of combined ETV/CPC is 0.59 (95% CI (0.53, 0.64), I2 = 82%). Etiology-based success rate is 0.71, 0.70, 0.64, and 0.52 for aqueductal stenosis, myelomeningocele, postinfectious hydrocephalus, and posthemorrhagic hydrocephalus, respectively. The overall complication rate is 0.04 (95% CI (0.02, 0.05), I2 = 14%). Our study presents a comprehensive analysis of the current evidence on the use of ETV/CPC for treating hydrocephalus in infants. The findings demonstrate the potential efficacy of this procedure; however, it is crucial to acknowledge the limitations inherent in the included studies, such as selection bias and limited follow-up, which could have impacted the reported outcomes.

RESUMO

OBJECTIVES: To estimate the risk of post-vasectomy infections in various settings and across various surgical techniques and sanitization practices. PATIENTS AND METHODS: Retrospective review of the records of 133,044 vasectomized patients from four large practices/network of practices using the no-scalpel vasectomy (NSV) technique in Canada (2011-2021), Colombia (2015-2020), New Zealand (2018-2021), and the United Kingdom (2006-2019). We defined infection as any mention in medical records of any antibiotics prescribed for a genital or urinary condition following vasectomy. RESULTS: Post-vasectomy infection risks were 0.8% (219 infections/26,809 procedures), 2.1% (390/18,490), 1.0% (100/10,506), and 1.3% (1,007/77,239) in Canada, Colombia, New Zealand, and the UK, respectively. Audit period comparison suggests a limited effect on the risk of infection of excising a short vas segment, applying topical antibiotic on scrotal opening, wearing a surgical mask in Canada, type of skin disinfectant, and use of non-sterile gloves in New Zealand. Risk of infection was lower in Colombia when mucosal cautery and fascial interposition [FI] were used for vas occlusion compared to ligation, excision, and FI (0.9% vs. 2.1%, p<0.00001). Low level of infection certainty in 56% to 60% of patients who received antibiotics indicates that the true risk might be overestimated. Lack of information in medical records and patients not consulting their vasectomy providers might have led to underestimation of the risk. CONCLUSION: Risk of infection after vasectomy is low, about 1%, among international high-volume vasectomy practices performing NSV and various occlusion techniques. Apart from vasectomy occlusion technique, no other factor modified the risk of post-vasectomy infection.

RESUMO

Background and Objectives: Endoscopic sphenopalatine artery cauterization (ESPAC) has become a reliable and effective surgical procedure for managing posterior epistaxis. The objectives of our study were to evaluate the effectiveness of ESPAC in the management of posterior epistaxis and the possible factors that lead to the failure of the procedure. Materials and Methods: We performed a retrospective analysis of all patients who underwent ESPAC between 2018 and 2022. We retrospectively reviewed the demographic data, patients' co-morbidities, medical treatment conditions, whether other surgical procedures were performed in addition to the ESPAC, and the success rate of ESPAC. Results: 28 patients were included in our study. After ESPAC, epistaxis was successfully managed in 25 patients (89.28%). Of all patients undergoing ESPAC, three (10.7%) presented re-bleeding. In two patients, we performed an endoscopic revision surgery with re-cauterization of the sphenopalatine foramen area, together with anterior and posterior ethmoidectomy, followed by fat occlusion/obliteration of these sinuses. In one patient, fat obliteration of the anterior and posterior ethmoid was also unsuccessful, and we performed an external carotid artery ligation at the level of the neck with no recurrence afterwards. Conclusions: Endoscopic cauterization of the sphenopalatine artery remains a safe, effective, and reliable surgical procedure in the management of recurrent posterior epistaxis. The use of anticoagulant drugs and the association of hypertension and other heart and liver diseases do not materialize as factors influencing surgical failure.

RESUMO

Objetivo La cistoscopia y la cauterización realizadas en el quirófano suponen un coste elevado y exponen a los pacientes a los riesgos asociados a la anestesia. La tolerabilidad de los pacientes durante la cistoscopia y la cauterización en la consulta es fundamental para el tratamiento ambulatorio del cáncer de vejiga y otras enfermedades urológicas. Se evaluaron los factores de riesgo asociados con el dolor percibido en la cistoscopia flexible en consulta, evaluando de manera independiente a un subgrupo de pacientes con cáncer de vejiga sometidos a cauterización. Materiales y métodos Análisis retrospectivo de 110 encuestas anónimas de pacientes completadas después de una cistoscopia y/o cauterización. La información de la encuesta incluía la edad, el sexo, la indicación de la cistoscopia, el número de cistoscopias previas, el número de cauterizaciones ambulatorias previas, la ansiedad antes/durante la cistoscopia y el dolor durante la cistoscopia y/o la cauterización. Se realizaron análisis univariantes/multivariantes y de regresión lineal para evaluar la asociación del dolor con los parámetros clínicos. Resultados El promedio del dolor percibido durante la cistoscopia (1,75±1,331) no difirió significativamente cuando se realizó también la cauterización (2,37±2,214) (p<0,001) (p=0,2840). Los pacientes del grupo de menor edad (<66 años) indicaron mayor ansiedad (p=0,0005), más dolor durante la cistoscopia (p=0,004) y la cauterización (p<0,001). Aunque el nivel de ansiedad general de los pacientes durante el procedimiento era bajo (1-3/10), se asoció con cierto nivel de dolor durante la cistoscopia (p=0,0005) y la cauterización (p<0,000). En el análisis multivariante, la ansiedad fue el único predictor independiente del dolor durante la cistoscopia (p=0,03; OR: 6,52; IC 95%:1,2-35,6) y la cauterización (p=0,0012; OR: 3,4; IC 95%:1,6-7,0)(AU)


Objective Cystoscopy and cauterization performed in the operating room is expensive and exposes patients to anesthesia risks. Patient tolerability during office cystoscopy and cauterization is critical to the office management of bladder cancer and other urologic diseases. We evaluated the risk factors for pain of flexible cystoscopy in the office-setting with emphasis on a sub-group of bladder cancer patients who underwent cauterization. Materials and methods Retrospective analyses of 110 anonymous patient surveys completed after cystoscopy and/or cauterization. Survey information included age, gender, purpose of cystoscopy, number of prior cystoscopies, prior number of office-cauterizations, anxiety prior/during cystoscopy, and pain during cystoscopy and/or cauterization. Univariate/multivariate and linear-regression analyses were performed to evaluate the association of pain with clinical parameters. Results Average pain during cystoscopy (1.75±1.331) was not significantly different when cauterization was also performed (2.37±2.214) (P<.001) (P=.2840). Patients in the lower age group (<66 years) indicated higher anxiety (P=.0005), more pain at cystoscopy (P=.004) and cauterization (P<.001). Although the patient's overall anxiety level was low (1–3/10), it was associated with some pain during cystoscopy (P=.0005) and cauterization (P<.000). In multivariate analysis, anxiety was the only independent predictor of pain during cystoscopy (P=.03, OR: 6.52, 95%CI: 1.2-35.6) and cauterization (P=.0012, OR: 3.4, 95%CI: 1.6-7.0) (AU)

RESUMO

BACKGROUND: Pyogenic granuloma (PG) is a common benign vascular neoplasia. Optimal treatment should have an aesthetically pleasant scar and a low recurrence rate. No treatment method that is fully effective in solving these has been demonstrated. Silver nitrate cauterization is another method for the management of PG lesions. OBJECTIVE: The effects of silver nitrate on the treatment of PG have not been sufficiently investigated and should be investigated with objective data and a controlled study. METHODS: The prospective clinical trial was designed to compare silver nitrate cauterization with surgical excision treatment. Procedure times and procedure costs, comfort and satisfaction scales, recurrences, the Patient and Observer Scar Assessment Score, and the Vancouver Scar Scale were compared to evaluate treatments. RESULTS: Silver nitrate treatment had lower procedure times, costs, and better satisfaction and comfort scale scores. The scar assessment scores were better for the silver nitrate treatment. The patients in both groups were successfully treated and no recurrence was seen. CONCLUSION: Silver nitrate cauterization is low-cost, fast, safe, reliable, and effective with good aesthetic results for the treatment of PG lesions. This study shows that silver nitrate cauterization is a good alternative to surgical excision in the management of PG.

RESUMO

BACKGROUND: Cerebral hemispherectomy can effectively treat unihemispheric epilepsy. However, posthemispherectomy hydrocephalus (PHH), a serious life-long complication, remains prevalent, requiring careful considerations in technique selection and postoperative management. In 2016, we began incorporating open choroid plexus cauterization (CPC) into our institution's hemispherectomy procedure in an attempt to prevent PHH. OBJECTIVE: To determine whether routine CPC prevented PHH without exacerbating hemispherectomy efficacy or safety. METHODS: A retrospective review of consecutive patients who underwent hemispherectomy for intractable epilepsy between 2011 and 2021 was performed. Multivariate logistic regression was used to identify factors independently associated with PHH requiring cerebrospinal fluid (CSF) shunting. RESULTS: Sixty-eight patients were included in this study, of whom 26 (38.2%) underwent CPC. Fewer patients required CSF shunting in the CPC group (7.7% vs 28.7%, P = .033) and no patients who underwent de novo hemispherectomy with CPC developed PHH. Both cohorts experienced seizure freedom (65.4% vs 59.5%, P = .634) and postoperative complications, including infection (3.8% vs 2.4%, P = .728), hemorrhage (0.0% vs 2.4%, P = .428), and revision hemispherectomy (19.2% vs 14.3%, P = .591) at similar rates. Patients without CPC had greater odds of developing PHH requiring CSF shunting (odds ratio = 8.36, P = .026). The number needed to treat with CPC to prevent an additional case of PHH was 4.8, suggesting high effectiveness. CONCLUSION: Preventing PHH is critical. Our early experience demonstrated that routinely incorporating CPC into hemispherectomy effectively prevents PHH without causing additional complications, especially in first-time hemispherectomies. A multicenter randomized controlled trial with long-term follow-up is required to corroborate the findings of our single-institutional case series and determine whether greater adoption of this technique is justified.

RESUMO

Background Although partial onychectomy with chemical matricectomy has been described as the treatment of choice, there is sparse evidence in the literature regarding the use of silver nitrate for matricectomy. Our aim is to describe the effectiveness of silver nitrate for matrix cauterization after partial onychectomy. Methods A prospective observational study was performed on patients with ingrown toenails stage 2–3 who underwent partial onychectomy with silver nitrate chemical matricectomy during 2018–2019 in our institution. All patients were evaluated in the outpatient clinic on the 7th and 30th post-operative day and a telephone evaluation was performed every 6 months after the surgical procedure to date. Results One hundred and twenty-three patients, who underwent 231 partial onychectomies with silver nitrate chemical matricectomy were included, with a median follow-up of 21 months (interquartile range, 12–29). The procedure had an effectiveness of 95.3%, with only 11 recurrences (4.7%) reported so far on follow-up. Postoperative infections were observed in 4 patients (1.7%). Adverse effects, such as pain and postoperative drainage, were irrelevant in most patients. Conclusions Silver nitrate matricectomy after partial onychectomy is an effective and safe alternative for the treatment of ingrown toenail in children, with scarce postoperative morbidity and low recurrence rate (AU)

RESUMO

OBJECTIVE: The success rate of endoscopic third ventriculostomy with choroid plexus cauterization (ETV/CPC) in the management of posthemorrhagic hydrocephalus (PHH) following intraventricular hemorrhage (IVH) in infants is not well defined. Furthermore, parameters of IVH at initial presentation have not been tested for predictive associations of ETV/CPC success in this setting. The authors sought to summarize their institutional outcomes to identify possible predictors of ETV/CPC success within this niche. METHODS: A retrospective review was conducted of all ETV/CPC procedures performed at the authors' institution for PHH between 2011 and 2021. Patients were screened against a set of selection criteria including follow-up time of at least 6 months. Associations with ETV/CPC failure were evaluated using regression and Kaplan-Meier analyses. RESULTS: A total of 50 patients satisfied all criteria. There were 32 (64%) male and 18 (36%) female patients with a mean gestational birth age of 26 weeks. The presenting IVH was symmetric in 30 (60%) and asymmetric in 20 (40%) patients, and the maximum IVH grade was IV in 30 (60%) patients overall. Six months after the procedure, ETV/CPC success was seen in 18 (36%) patients and failure in 32 (64%) patients. The median overall follow-up was 42 months, at which point ETV/CPC success was observed in 11 (22%) patients and ETV/CPC failure in 39 (78%) patients. Regression analyses indicated that radiological IVH symmetry was a statistically significant predictor of ETV/CPC failure at 6 months (OR 3.46, p = 0.04) and overall (OR 5.33, p = 0.03). Overall rates of failure were 89% versus 62% (p = 0.02) when comparing symmetric versus asymmetric IVH patients, and time to failure occurred at median times of 1.4 versus 6.5 months (p = 0.03) after the initial procedure. Higher maximum IVH grade and younger age at initial ETV/CPC only trended toward increased failure rates. When the etiology component of the ETV Success Score was adjusted such that symmetric IVH was scored 0, the area under the curve for failure at 6 months increased from 0.58 to 0.69. CONCLUSIONS: Overall, approximately 1 in 5 infants with PHH can expect to not require further intervention following ETV/CPC. The authors demonstrate that IVH symmetry is statistically predictive of ETV/CPC failure in this setting independent of all other parameters, where PHH infants with symmetric IVH are more likely to experience failure, and sooner, than PHH infants with asymmetric IVH. When discussing possible success rates of ETV/CPC for PHH, IVH symmetry should be considered.

RESUMO

Nasal turbinate hypertrophy is among the most common nasal obstruction disorders, affecting the patient's quality of life significantly. Endoscopic submucosal diathermy is a prevalent cauterization procedure for treating turbinate hypertrophy. Regrettably, the nasal burn associated with diathermy typically heals slowly causing facial pain and nasal bleeding and possibly resulting in synechiae formation. In the current study, we have developed, for the first time, a polymeric film loaded with cholecalciferol for local treatment of nasal burns. The casting method was used to prepare films of different compositions of polymers such as chitosan, polyvinyl alcohol (PVA), Carbopol 971p (CP971p), and hydroxypropyl methylcellulose (HPMC) as well as a plasticizer. Several characterizations were performed for the cholecalciferol-loaded films (e.g. weight, thickness, content uniformity, surface pH, folding endurance, disintegration time, and in vitro release) to select the optimal formulation. The optimal formulation (F4) displayed compatibility between the used polymers and the drug. In vivo animal study was carried out to assess the healing efficacy of the formulated cholecalciferol-loaded film. The rabbits treated with the cholecalciferol-loaded film demonstrated significantly higher mRNA expression of the growth factor TGF-ß and significantly lower mRNA expression of the proinflammatory cytokine TNF-α and IL-1ß compared to the plain film treated group and the untreated control group. A randomized, single-blinded, parallel, controlled clinical trial was conducted on 20 patients scheduled to undergo endoscopic submucous diathermy. The results of the clinical study demonstrated significant reductions in facial pain and nasal bleeding scores for the nostrils treated with cholecalciferol-loaded films in comparison to the nostrils treated with plain films. Furthermore, the endoscopic examination showed good healing for 95% of the cholecalciferol-loaded film-treated nostrils. In conclusion, the optimized film can be considered an opportune approach for enhancing the healing rate of nasal burns and thus reducing the downsides of the diathermy procedure.

RESUMO

Objetivo: Los pacientes con cáncer de vejiga (CV) Ta, de grado bajo (GB) 1-2, presentarán con frecuencia una «recidiva», aunque rara vez una progresión a un estadio más avanzado. Si bien las directrices actuales mencionan la vigilancia y el manejo en consulta para estos tumores nuevos o recurrentes, la resección transuretral es el tratamiento realizado con mayor frecuencia. El objetivo de este estudio es determinar la seguridad de la vigilancia y/o la cauterización ambulatoria. Materiales y métodos: Este estudio se llevó a cabo como un análisis retrospectivo de una serie de casos de 45 pacientes que tenían CV recurrente con apariencia de GB Ta y que fueron tratados principalmente con vigilancia y/o cauterización en la consulta. Se excluyeron los pacientes con carcinoma in situ. La variable de valoración principal fue la progresión a un estadio más avanzado. Resultados: La mediana de seguimiento fue de 62 meses. En 41 (91%) pacientes no hubo progresión del estadio. Tres pacientes recidivaron con CV grado alto (GA) T1; uno de ellos está recibiendo inmunoterapia sistémica. Un paciente desarrolló un CV GA T2 y fue tratado con un protocolo preservador de la vejiga. A 40 (89%) pacientes se les realizó cauterización en consulta. Once recibieron BCG y 26 recibieron quimioterapia intravesical tras la cauterización. Cinco (11%) pacientes desarrollaron CV GA durante el seguimiento. Ningún paciente falleció. Ninguno de los 17 (38%) pacientes hispanos tuvo progresión.ConclusionesLa vigilancia activa y/o la cauterización ambulatoria para pacientes con tumores vesicales pequeños GB Ta es segura, reduce costes y mejora la calidad de vida al evitar las resecciones transuretrales.

Objective: Patients with low-grade (LG), grade 1-2, Ta bladder cancer (BC) will frequently have a “recurrence”. However, they rarely progress in stage. Although current guidelines mention surveillance and office management for these new or recurrent tumors, transurethral resection is the most common treatment. The purpose of this study is to determine if surveillance and/or office cautery is safe. Materials and methods: This study was conducted as a retrospective case series analysis of 45 patients who had recurrent LG Ta appearing BC and were managed primarily with surveillance and/or office cautery. Patients with carcinoma in-situ were excluded. The primary outcome was stage progression. Results: Median follow-up was 62 months. Forty-one (91%) patients did not progress in stage. Three patients recurred with high grade (HG) T1 BC; one is receiving systemic immunotherapy. One patient developed HG T2 BC and was treated with a bladder preservation protocol. Forty (89%) patients underwent office cauterization. Eleven received BCG and 26 received post-cautery intravesical chemotherapy. Five (11%) patients developed HG BC during follow-up. No patients died. None of the 17 (38%) Hispanic patients had progression. Conclusions: Active surveillance and/or office cautery for patients with small recurrent LG Ta bladder tumors is safe, reduces cost and improves quality of life by avoiding transurethral resections.

RESUMO

BACKGROUND: Choroid plexectomy was first performed around 1910. Later, the technique evolved into subtotal choroid plexus cauterization (CPC) but was largely abandoned following the invention of the ventriculoperitoneal shunt. Over time, with improved understanding of the pathophysiology of hydrocephalus and improvement in endoscopic techniques and equipment, the procedure of CPC was reintroduced. However, little is known about the biomolecular consequences of ablation of a significant portion of the choroid plexus on metabolic brain homeostasis, neurogenesis, and neuroimmunology. SUMMARY: The physiological functions of choroid plexus in neurogenesis and neuroimmunology and its role in diseases, such as AD and MS, should alert to possible as yet to be determined consequences. Studies, both in children and in adults, are needed not only on the success in hydrodynamic stabilization of hydrocephalus but also on the long-term outcome, especially premature neurodegeneration and inflammatory changes and on compensatory metabolic mechanisms. KEY MESSAGES: The value of CPC for treatment of hydrocephalus in medically underserved areas should be remembered, yet when alternative treatment options are available, we cannot responsibly advocate against or for the use of CPC. Therefore, perhaps a more detailed discussion of risks and benefits of a CPC with parents would be best to include the possible implications in brain development and function.

RESUMO

Neonatal hydrocephalus represents an important pathological condition with significant impact on medical care and neurocognitive development. This condition requires early recognition, appropriate medical and surgical management, and long-term surveillance by clinicians and pediatric neurosurgeons. Common etiologies of neonatal and infant hydrocephalus include intraventricular hemorrhage related to prematurity with subsequent post-hemorrhagic hydrocephalus, myelomeningocele, and obstructive hydrocephalus due to aqueductal stenosis. Clinical markers of elevated intracranial pressure include rapid increases in head circumference across percentiles, elevation and firmness of the anterior fontanelle, splitting or splaying of cranial sutures, upgaze palsy, lethargy, frequent emesis, or episodic bradycardia (unrelated to other comorbidities). Complementing these clinical markers, imaging modalities used for the diagnosis of neonatal hydrocephalus include head ultrasonography, brain magnetic resonance imaging, and head computed tomography in urgent or emergent situations. Following diagnosis, temporizing measures may be employed prior to definitive treatment and include ventricular access device or ventriculo-subgaleal shunt insertion. Definitive surgical management involves permanent cerebrospinal fluid (CSF) diversion via CSF shunt insertion, or endoscopic third ventriculostomy with or without choroid plexus cauterization. Surgical decision-making and approaches vary based on patient age, hydrocephalus etiology, neuroanatomy, imaging findings, and medical comorbidities. Indications, surgical techniques, and clinical outcomes of these procedures continue to evolve and elicit significant attention in the research environment. In this review we describe the epidemiology, pathophysiology, clinical markers, imaging findings, early management, definitive surgical management, and clinical outcomes of pediatric patients with neonatal hydrocephalus.

RESUMO

BACKGROUND: Ingrown nails are frequently encountered in dermatology practice. The recurrence tendency of the disorder makes chemical cauterization essential during surgical procedures. In studies comparing nail matrix cauterization with sodium hydroxide (NaOH) versus phenol, phenol's application time was highly variable. OBJECTIVE: To compare the therapeutic outcomes of matrix cauterization for a standard duration of one minute for NaOH versus phenol in stage II and III ingrown nails. MATERIAL AND METHODS: The medical records of patients undergoing matrix cauterization with 10% NaOH or 88% phenol were evaluated. The primary outcome measure was the lack of recurrences on long-term follow-up. The secondary outcome measures were complete healing duration, patient-reported pain scores, and adverse effects related to the procedure. RESULTS: Enrolled in this study were 62 ingrown toenail sides treated with 10% NaOH and 56 ingrown toenail sides treated with 88% phenol. The mean follow-up duration was 25.17 months. Recurrence was observed in four nail sides of the NaOH group (%6.45) and three nail sides of the phenol group (%5.35). The difference between the recurrence rates did not reach statistical significance. Patients treated with both methods were free of pain on the post-procedural tenth day. The visual analog scale pain scores and complete healing duration were similar between the two groups (p>0.05). CONCLUSION: In a large group with long-term follow-up results, the short-term and long-term post-operative treatment outcomes were similar between the one-minute applications of 10% NaOH versus 88% phenol groups.

RESUMO

OBJECTIVES: Obliteration with cauterization of the internal opening of pyriform sinus fistulas, with or without marsupialization, has been a mainstay for preventing recurrence. However, this procedure predisposes patients to recurrence caused by the reopening of the cauterized orifice. We applied suture ligation to secure the closure of the internal orifice following cauterization and evaluated treatment. METHODS: A total of 42 patients were diagnosed with third or fourth branchial cleft anomaly with internal pyriform sinus fistula and treated either with cauterization or with cauterization and suture ligation, between January 2008 and December 2020. The medical records were reviewed to assess demographic characteristics, clinical presentations, diagnoses, surgical treatment, and outcomes. Treatment flow characteristics for intractable patients were analyzed. RESULTS: The median age of onset was 9 years (range, 0-57 years). Neck swelling (n = 32, 76.2%) was commonly encountered symptom, and a history of neck infection was found in 27 patients (64.3%). After initial treatment, 11 cases (56.2%) recurred. Younger age (≤9 years) and thyroid involvement were associated with recurrence (P = .034 and P = .046, respectively). Cauterization with suture ligation presented lower recurrence rate (19.2%) than cauterization only (37.5%, P = .037). Cauterization with suture ligation for recurrent cases (n = 11) showed 81.8% (9/11) of cure rate. Intractable fistulas (n = 2) from both groups were also salvaged by suture ligation. CONCLUSIONS: Suture ligation with cauterization for an internal orifice of branchial anomaly showed lower recurrence rate than cauterization only. This method was beneficial for refractory cases.

RESUMO

BACKGROUND: Third and fourth branchial anomalies are rare, accounting for less than 10% of all branchial anomalies. The piriform fossa sinus tract (PFST) typically presents with left-side suppurative thyroiditis, although it can present earlier in neonates as a non-inflamed cystic neck mass. PFST poses a considerable diagnostic challenge with variable clinical and imaging features, leading to long delays to definitive diagnosis and appropriate management. OBJECTIVE: To analyse the patterns of presentation and imaging findings in children with PFST, with a particular focus on neonatal presentation. MATERIALS AND METHODS: This was a retrospective review of the clinical presentation, imaging findings and management in 16 cases of PFST presenting to our tertiary children's hospital between 2003 and 2018. Cases were identified by medical records and picture archiving and communication system (PACS) search using relevant International Classification of Diseases (ICD)-10 coding. RESULTS: Age at presentation ranged from prenatal to 16 years, with a male-to-female ratio of 2:1. All patients presented with neck swelling. Thirteen patients (81%) had suppurative thyroiditis at initial presentation. Two patients had severe thyroiditis/mediastinitis that required intensive care unit admission. Three neonates presented with noninfected, asymptomatic large cystic neck masses; two of these were detected prenatally and misdiagnosed as lymphatic malformations with subsequent spontaneous clinical resolution that later represented with evidence of PFST. The PFST was on the left side in 15/16 (94%) patients. All patients had neck imaging before definitive diagnosis. Imaging studies included radiographs, ultrasound, computed tomography, magnetic resonance imaging and barium esophagram studies. No single modality was diagnostic of PFST in all patients. Seventy-five percent of patients had multimodal imaging before diagnosis. All PFSTs were confirmed by endoscopic visualisation. Management of PFST was by endoscopic cauterisation in 13 patients and open surgery in 2. One patient did not require surgical correction. CONCLUSION: Our study highlights the complex nature of PFST. The anomaly is uncommon, has variable clinical and imaging features and may have a lengthy, complicated course if not considered at initial presentation. An episode of suppurative thyroiditis in a child should prompt investigation for PFST. We describe atypical presentations with cystic masses in neonates that appear to resolve but represent later as typical clinical features of PFST.

RESUMO

INTRODUCTION: Inadequate absorption of cerebrospinal fluid (CSF) in the setting of high CSF production is a relatively rare cause of shunt malfunction. CASE REPORT: We present the unique case of a 3-year-old boy who developed sterile ascites and abdominal distension in a delayed fashion after shunt placement. The shunt was externalized, and the patient was noted to have high CSF output. Bilateral choroid plexus cauterization resulted in a significant decrease in CSF production and enabled the shunt to be re-inserted into the abdomen.
