Pediatric Epistaxis-Effectiveness of Conservative Management.

OBJECTIVES: Epistaxis is an emergency medical condition that sometimes requires admission to the emergency department. Pediatric epistaxis differs from epistaxis in the older population in terms of etiology, severity, and management. Our objective was to identify the distinctive features of pediatric epistaxis and determine the appropriate management. METHODS: This was a retrospective study of 231 medical records of children (<18 years old) with epistaxis of a total of 1171 cases in the general population who presented to our medical center's emergency department between 2013 and 2018. RESULTS: Among 231 admissions, 10 children (4.3%) presented more than once. Male patients accounted for the majority of cases (64.5%), and the average age was 9.4 years. Two children were treated with aspirin because of cardiac valve disease. Anterior bleeding was detected in 101 cases (43.7%), whereas posterior origin was observed in 8 cases (3.5%). In 122 cases (52.8%), there was no active bleeding observed. Nose injury was the cause of epistaxis in 24 cases (10.4%), and 16 admissions (6.9%) followed nasal surgical interventions. Nineteen children (8%) had abnormal coagulation tests, and 7 patients (3%) received blood transfusions. Chemical cauterization was performed in 89 cases (39.3%), and anterior packing was needed in only 9 cases (3.9%). Nine children required hospitalization (3.9%), and 2 needed surgical intervention to control bleeding. Compared with the adult population, there were significantly fewer cases of active bleeding, recurrent epistaxis, anterior packing, or need for hospitalization in the pediatric population. CONCLUSIONS: Epistaxis is significantly less severe in the pediatric population, with only a few cases requiring major intervention. Endoscopic examination of the entire nasal cavity and routine coagulation tests are not mandatory unless there is a history of recurrent epistaxis, known coagulopathy, antiplatelet/anticoagulation therapy, or a suspicion of juvenile idiopathic angiofibroma. We suggest using absorbable packs, which offer advantages over cauterization or nonabsorbable packs.

Endoscopic Chemocauterization with Trichloroacetic Acid for Congenital or Recurrent Tracheoesophageal Fistula in Children with Esophageal Atresia: Experience from a Tertiary Center.

BACKGROUND: Recurrent tracheoesophageal fistula (rTEF) is a well-known complication after surgery of EA, occurring in roughly 3-10% of the patients. Recent studies have highlighted safety and efficacy of endoscopic management of recurrent TEF. The aim of this study was to evaluate the efficacy of chemocauterization with trichloroacetic acid (TCA) in rTEF and congenital tracheoesophageal fistula (cTEF). METHODS: Retrospective chart review of consecutive patients with recurrent or congenital TEF who underwent endoscopic chemo-cauterization between 2018 and 2022 at a tertiary center. Children diagnosed with TEF who underwent primary or secondary endoscopic treatment were included. Median follow up time was 19 months for rTEF and 33 months for cTEF. RESULTS: During the study period, 18 patients were treated endoscopically by chemocatuerization with TCA at our institution. Treatment of recurrent TEF was successful in 13 of 14 patients (93%) Treatment of congenital TEF was successful in 2 of 4 patients (50%). In 14 patients, closure was seen after 1-2 treatments. There were no serious adverse reactions or complications to the endoscopic treatment of TEF. CONCLUSION: Endoscopic chemocauterization is a minimal invasive technique with low morbidity and high success rate and may be considered as primary treatment for recurrent TEF. LEVEL OF EVIDENCE: III.

Comparing recurrence between cautery techniques in pediatric epistaxis.

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.

Endoscopic Sphenopalatine Artery Cauterization in the Management of Recurrent Posterior Epistaxis.

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.

Comparison of the Efficacy of Combined Silver Nitrate Coagulation and Shave Excision With Surgical Excision and Linear Closure in the Treatment of Pyogenic Granuloma.

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.

Therapeutic outcomes of one-minute application of sodium hydroxide versus phenol in the chemical cauterization of ingrown toenails.

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.

Piriform fossa sinus tract - a 15-year retrospective review with a focus on atypical neonatal presentations.

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.

Alternative sources of cautery may improve post-operative hematoma rates but increase operative time in thyroid surgery.

A retrospective risk-adjusted analysis was completed using data from the National Surgical Quality Improvement Program (NSQIP) to (1) compare the risks of post-operative hematoma for thyroid surgery using conventional cautery compared alternative energy devices (defined as LigaSure and Harmonic Scalpel), and (2) compare operative times for the same. The primary outcome variable was post-operative hematoma occurrence. The secondary outcome variable was operative time. The exposure variable was use of conventional or alternative sources of cautery. All adult patients who underwent a total thyroidectomy, subtotal thyroidectomy or completion thyroidectomy between 2016 and 2018 were included. Multivariable linear and logistic regression analyses were performed to control for potentially confounding variables. A total of 13,330 cases were analyzed; 4342 used conventional cautery, and 8988 used alternative sources. There was a statistically significant decrease in post-operative hematoma risk using alternative sources of cautery compared to conventional cautery (OR 0.75; 95% CI 0.58-0.98) (p = 0.04). Use of alternative sources of cautery added 4.95 min onto operative time (95% CI 2.45-7.45) which was statistically significant (p < 0.0001). After controlling for confounding variables, there was a statistically significant lower rate of post-operative hematoma in thyroidectomies performed using alternative sources of cautery compared to those performed with traditional hemostatic methods. Alternative sources of cautery increased operative time by 4.95 min.

Development of a tibial experimental non-union model in rats.

BACKGROUND: Many non-union animal models have been developed to explore the problems surrounding fracture healing. However, the existing models are not perfect and cannot satisfy all non-union studies. This study aimed to make a non-union model of the tibia in rats by cauterization of the posterior of 2 mm on both sides of the fracture end after open osteotomy of the tibia and fixing the fractured tibia with a Kirschner wire 0.8 mm in diameter. METHODS: For this study, 96 female adult Sprague-Dawley (SD) rats were used. The rats underwent surgery to produce a tibial open fracture and were fixed with a 0.8-mm diameter Kirschner wire. In 48 of the rats, the periosteum proximal and distal to the fracture end was cauterized. RESULTS: At 2, 4, 6, and 8 weeks after surgery, radiological and histological analysis showed typical physiological healing in the control group, and the healing rate was 100% at 6 weeks. But the non-union group was characterized by resorption of the fracture ends with few callus formations and no bridging callus formation, and the healing rate was 0% at 8 weeks. CONCLUSIONS: This method represents a reproducible model to create atrophic non-unions. This model provides a new option for studying the basic healing mechanisms and evaluating new therapies for bone regeneration and treatment of non-unions.

Mid-term results of intralesional extended curettage, cauterization, and polymethylmethacrylate cementation in the treatment of giant cell tumor of bone: A retrospective case series.

OBJECTIVE: The aim of this study was to present the mid-term functional outcomes and recurrence rate in patients with giant cell tumor of bone (GCTB) treated by intralesional extended curettage, electrocauterization, and polymethylmethacrylate (PMMA) cementation. METHODS: In this retrospective observational study, 79 consecutive patients (41 females, 38 males; mean age=39 years; age range=19-62 years) who were diagnosed and treated for GCTB between 2005 and 2017 were identified from hospital medical records. All patients were treated by intralesional extended curettage using high-speed burr, electrocauterization of the cavity, and filling the defect with PMMA. No additional local adjuvants were used. The mean follow-up period was 47 months (range=24-96). The tumors were graded according to the radiological classification system described by Campanacci. Functional outcomes were evaluated using the Musculoskeletal Tumor Society Score (MSTS) preoperatively, one year postoperatively, and at the final follow-up. Postoperative complications and recurrence rates were recorded. RESULTS: Twenty-nine tumors were located in the distal femur, 23 in the proximal tibia, nine in the distal radius, five in the proximal humerus, five in the pelvis, three in the proximal fibula, two in the distal ulna, two in the distal tibia, and one in the second metatarsal. According to Campanacci classification, 37 tumors were grade III, 32 grade II, and 10 grade I. The mean MSTS score was 46.1% (range 40.2 to 71.4%) preoperatively, 91.7% (range 73.3% to 100%) one year postoperatively, and 86.3 % (range 66.2% to 96,1%) at the final follow-up. The overall complication rate was 7.6%; which included local tumor recurrence in four patients, superficial wound infection in one, and deep wound infection in another. The recurrence rate was 5.1% (4 patients). Recurrent tumors were located at the distal femur in three patients and proximal tibia in one. CONCLUSION: With satisfactory functional results and low recurrence rates at the mid-term follow-up, GCTB can be treated effectively with intralesional extended curettage, electrocauterization, and PMMA cementation. LEVEL OF EVIDENCE: Level IV, Therapeutic study.

Effectiveness of TCM cauterization in recurrent tonsillitis: A protocol for systematic review and meta-analysis.

INTRODUCTION: Recurrent tonsillitis (RT) is often treated with antibiotic therapy and surgery. Although these treatments have advantages, they are also controversial. The purpose of this study is to analyze the safety and effectiveness of traditional Chinese medicine (TCM) cauterization in the treatment of RT, so as to provide an alternative for the clinicians and to cover the shortage of therapeutic methods. METHODS AND ANALYSIS: This protocol is guided by the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) and by the Cochrane Collaboration Handbook. We will formulate strict inclusion and exclusion criteria in English databases (PubMed, EMBASE, and Web of Science), Chinese databases (CNKI, Wanfang databases, CBM, and VIP), and search literatures in different clinical registration platforms (Cochrane Library, Chinese Cochrane Centre's Clinical Trial Registry Platform). The included articles will be evaluated using Cochrane RCT evaluation criteria. Stata 15.0 will be used for data analysis. Subgroup analysis, sensitivity analysis, and meta-regression will detect sources of heterogeneity. Egger's Test or Begg's Test will detect publication bias quantitatively. CONCLUSION: Cauterization can effectively control the recurrence of tonsillitis through clinical trials, but evidence-based medicine needs to be adopted to provide strong evidence for its effectiveness. The purpose of our research is to provide the evidence. OSF REGISTRATION NUMBER: DOI 10.17605/OSF.IO/PZ69Q.

Fourth branchial pouch anomaly presenting as a neonatal neck lump.

A 1-week-old female infant presented with a transilluminating neck lump that increased in size with crying. The presumptive diagnosis was lymphatic malformation, but imaging raised the possibility of an abscess or necrotic tumour. A biopsy revealed a likely developmental cyst with local inflammatory change. Microlaryngoscopy revealed a fourth branchial pouch sinus, which was cauterised. The sinus and neck lump resolved without need for further treatment.

The treatment of congenital pyriform sinus fistula: a single-center experience.

PURPOSE: Congenital pyriform sinus fistula (CPSF) often presents diagnosis and treatment challenges. This study aimed to explore the treatment principles and to evaluate the effectiveness of the hypothermia plasma cauterization with suspension laryngoscopy for CPSF. METHODS: The medical records of 56 patients with CPSF from January 2000 to December 2019 were retrospectively reviewed. RESULTS: Of the 56 cases, the lesions were predominantly located on the left side (95%), and the accuracy of the first diagnosis was 30%. Ultrasound showed an abnormal rate of 86%, while CT or MRI displayed an abnormal anatomic lesion of 92%. The 3D visual reconstruction enabled the analysis of morphological characteristics of CPSF. The positive predictive value of barium esophagography was 89%, whereas the positive rate of the internal opening in CPSF under local anesthesia laryngoscopy was 33%. Nine cases of sinus type underwent open resection, and the recurrence rate was 33%. Interestingly, ten patients with sinus type underwent hypothermia plasma cauterization with suspension laryngoscopy, leading to a success rate of 100% without apparent complications. CONCLUSIONS: Hypothermia plasma cauterization with suspension laryngoscopy alongside 3D imaging is both minimally invasive and repeatable with neglectable complications, which has the potential to serve as the first-line treatment for CPSF in the future.

Office-based inferior turbinate reduction using bipolar cautery: Technique and results.

OBJECTIVES: Several methods have been reported for inferior turbinate (IT) reduction. We describe office-based interstitial IT reduction using bipolar cautery and evaluate long-term efficacy. METHODS: Sixty patients with allergic and nonallergic rhinitis unresponsive to medical treatment underwent office IT reduction between January 2012 and December 2014. Bipolar cautery was used at 15 to 20 W. Mean procedure time was 12 min for unilateral and 16 min for bilateral IT reduction. Patients followed up at 2, 6, and 12 weeks and 1 year. Mean follow-up was 22 months. The Sinonasal Outcome Test was completed before and after at 6 weeks and 1 year. RESULTS: SNOT-22 scores were 35.7 ± 5.4 and 18.5 ± 4.2 preoperatively and at 1 year respectively. Symptoms improved at 6 weeks, nasal obstruction and rhinorrhea improving most. Complications included vaso-vagal reactions in 6 requiring rescheduling the procedure in 2 patients. One patient had bleeding controlled conservatively. CONCLUSION: Bipolar IT cautery is safe, effective, well-tolerated and doesn't require expensive equipments. It can be incorporated into general otolaryngology practice.

Comparison of microwave ablation and chemical cautery used to control adult idiopathic recurrent anterior epistaxis.

OBJECTIVE: This study compared the efficacy of microwave ablation and silver nitrate cautery as treatments for idiopathic recurrent anterior epistaxis in adults. METHODS: A case series with chart review was conducted. Adults with recurrent anterior epistaxis intra-operatively treated via microwave ablation or silver nitrate chemical cautery of the anterior nasal septum were enrolled. The primary outcomes were the proportion of patients in each group for whom bleeding ceased within 24 hours of treatment, and the time to successful haemostasis. The secondary outcomes were re-bleeding rates at 1 and 12 weeks and 6 months, and complications. RESULTS: The haemostasis success rate within 24 hours' treatment of convex lesions was significantly higher in the microwave ablation group than in the cautery-only group. Of patients with convex lesions, the recurrence rate to six months was significantly higher in the cautery group than in the microwave ablation group, but this was not the case for those with flat lesions. CONCLUSION: Microwave ablation afforded rapid and simple haemostasis for adults with recurrent anterior epistaxis in an out-patient setting. Microwave ablation had significant advantages compared to silver nitrate cautery when used to treat epistaxis in patients with convex lesions.

Racing performance of National Hunt thoroughbred racehorses after treatment of palatal dysfunction with a laryngeal tie-forward procedure and thermocautery of the soft palate with or without aryepiglottic folds resection.

OBJECTIVE: To assess racing performance of National Hunt thoroughbred (NH) racehorses with a definite diagnosis of palatal dysfunction treated with a laryngeal tie-forward procedure (LTF) and soft palate cautery (SPC) with or without transendoscopic laser excision of the aryepiglottic folds (TLEAF) and to determine correlation between performance measures. STUDY DESIGN: Retrospective cohort study. ANIMALS: National Hunt racehorses treated with LTF, SPC ± TLEAF (n = 44) and nonaffected controls (n = 88). METHODS: Performance was evaluated by using Racing Post ratings (RPR), race earnings (RE), and performance index (PIndex). Affected horses were compared with nonaffected horses. The effect of TLEAF and correlations between measures were analyzed. RESULTS: Racing Post rating, RE and PIndex improved by 50%, 26%, and 12% in treated, and by 50%, 39%, and 24% in control horses, respectively, when measurements were evaluated for the median of three presurgical and postsurgical races. Lower postsurgical performance was detected when five postsurgical races were compared with two presurgical races (P ≤ .03). The number of postsurgical earnings rated at zero was greater in treated horses than in control horses (P < .05). Race earnings and RPR correlated more strongly (r = 0.634-0.796) than PIndex and other measures (r = 0.378-0.692). CONCLUSION: Postsurgical performance of NH racehorses with palatal dysfunction after LTF and SPC ± TLEAF was decreased compared with unaffected controls. The negative effect of TLEAF on performance was detected. CLINICAL SIGNIFICANCE: Although LTF is widely performed in NH racehorses, it may not be the most efficient treatment for palatal dysfunction.

Cauterized suture for complete tube occlusion of Ahmed glaucoma valve in hypotony maculopathy.

PURPOSE: To present our experience treating hypotony maculopathy with a simple, minimally invasive, and removable ab interno tube Ahmed glaucoma valve occlusion. METHODS: Under topical anesthesia a 5-0 polypropylene suture (Prolene; Ethicon) was inserted into the Ahmed glaucoma valve tube. The length of the tube was measured, and an external suture cauterization was performed to allow an easier and safer fixation in the tube. The suture was introduced into the tube itself with the viscoelastic 27-gauge cannula. RESULTS: This technique was performed in three cases of hypotony maculopathy with a complex history of medical treatments: a 4-year-old boy with Donnai-Barrow syndrome and previous pars plana vitrectomy that developed hypotony maculopathy the day after Ahmed glaucoma valve insertion and two male patients (69 and 49 years old) that underwent hypotony maculopathy after cyclophotocoagulation as a last option to reduce intraocular pressure. One of the men had three filtering surgeries, two 5-fluorouracil needlings and Ahmed glaucoma valve insertion. The other male patient had keratoplasty and posterior Ahmed glaucoma valve insertion. In the three cases, both hypotony and maculopathy were reversed within a week and a month, respectively, after Ahmed glaucoma valve occlusion with no complications. When hypotony maculopathy develops it seems suitable to occlude completely the Ahmed glaucoma valve tube to swiftly reverse clinical and anatomic changes. CONCLUSION: Intraluminal Ahmed glaucoma valve occlusion with cauterized suture is a simple, quick, reversible, and effective technique that may offer a minimally invasive way to resolve hypotony maculopathy in complex cases and avoid severe loss of vision.

Giant Choroid Plexus Papilloma Resection Utilizing a Transcollation System.

BACKGROUND: Large vascular brain tumors pose an exceptional challenge in young children. Choroid plexus papilloma (CPP) is an example of a rare, often large and especially vascular neuroepithelial tumor that most commonly arises in children under 5 yr old. Although patients may be cured by total resection, this tumor poses significant surgical risks and challenges related to intraoperative hemostasis. OBJECTIVE: To describe our experience using a transcollation system during brain tumor surgery in a child to achieve hemostasis and minimize blood loss while preserving normal brain tissue. METHODS: A 3-yr-old girl presented following a fall and was found to have a giant CPP growing from the right lateral ventricle. Given the vascularity of the tumor and the low intravascular reserve in a small child, a transcollation device was used to reduce blood loss intraoperatively. RESULTS: Gross total resection was achieved with approximately 300 mL of blood loss without complications. The patient did well postoperatively. Imaging performed at 3 mo after resection revealed return of normal brain architecture. CONCLUSION: Transcollation devices appear to be an effective and safe addition to the armamentarium of neurosurgical hemostatic options in intracranial tumor resection in which there is a high risk of intraoperative hemorrhage.

The Cold Revolution: How Far Can It Go?

Cold resection for small colonic polyps, and larger lesions, is being rapidly and widely adopted. Driven by an impressive safety and cost profile compared with conventional polypectomy, these advantages are offset by the limitations of smaller and shallower resection, and absent thermal effects that may permit persistence of residual neoplasia. To overcome this, optimal cold snare technique requires inclusion of a margin of normal mucosa and a piecemeal resection technique for larger polyps. This article examines the fundamentals of cold snare resection and evidence for its application, theorizes on limits to its application, and identifies areas for further research.
