ABSTRACT
INTRODUCTION: Pediatric ovarian torsion (OT) is an emergency condition that remains challenging to diagnose because of its overall unspecific clinical presentation. The aim of this study was to determine the diagnostic value of clinical, ultrasound, and inflammatory laboratory markers in pediatric OT. METHODS: We performed a retrospective multicentric case-control study in patients with clinical and ultrasound suspicion of OT, in whom surgical examination was performed between 2016-2022 in seven pediatric hospitals. Patients were divided into two groups according to intraoperative findings: OT group (ovarian torsion), defined as torsion of the ovarian axis at least 360°, and non-OT group (no torsion). Demographics, clinical, ultrasound, and laboratory features at admission were analyzed. The diagnostic yield analysis was performed using logistic regression models, and the results were represented by ROC curves. RESULTS: We included a total of 110 patients (75 in OT group; 35 in non-OT group), with no demographic or clinical differences between them. OT-group patients had shorter time from symptom onset (8 vs. 12 h; p = 0.023), higher ultrasound median ovarian volume (63 vs. 51 mL; p = 0.013), and a significant increase in inflammatory markers (leukocytes, neutrophils, neutrophil-to-lymphocyte ratio, C-reactive protein) when compared to the non-OT group. In the ROC curve analysis, the neutrophil-to-lymphocyte ratio (NLR) presented the highest AUC (0.918), with maximum sensitivity (92.4%) and specificity (90.1%) at the cut-off point NLR = 2.57. CONCLUSIONS: NLR can be considered as a useful predictor of pediatric OT in cases with clinical and ultrasound suspicion. Values above 2.57 may help to anticipate urgent surgical treatment in these patients.
ABSTRACT
Laparoscopic elective splenectomy is considered as a safe surgical treatment of spleen non-traumatic blood disorders. However, robotic assisted splenectomy is becoming a promising alternative, although there are scarce studies in pediatric patients. Our aim is to compare the effectiveness and associated costs of both procedures in children. A single-institution retrospective study was performed among consecutive children undergoing splenectomy between 2004 and 2021, who were divided according to the surgical approach: LAS group (laparoscopic splenectomy) and RAS group (robotic assisted splenectomy). Demographics, clinical features, intraoperative blood loss, surgery time, length of hospital stay (LOS), postoperative complications, need for postoperative blood transfusion, readmission rate and economic data were compared. A total of 84 patients were included (23 LAS group; 61 RAS group), without demographic or clinical differences between them. RAS patients presented lower intraoperative blood loss (42 ± 15 vs. 158 ± 39 ml; p < 0.021) and shorter surgery time (135 ± 39 vs. 182 ± 68 min; p = 0.043), with no differences in median LOS (3 days in both groups). No intraoperative complications or conversion was reported. Five postoperative complications were observed: 4 in LAS patients (17.4%) versus only one in RAS (1.6%; p = 0.021). One reintervention was required in LAS group due to hemoperitoneum 12 h after splenectomy. RAS patients had lower postoperative blood transfusion requirements (1.6% vs. 13.0%; p = 0.025) and lower readmission rate (3.3 vs. 17.4%; p = 0.042). No differences were observed when comparing the median economic costs ($25,645 LAS vs. $28,135 RAS; p = 0.215). Robotic assisted splenectomy may be considered as a safe and feasible option in children compared to the traditional laparoscopic approach. Level of evidence: III.

Inguinal herniation of ureter is an uncommon finding among children, with scarce reported cases in the literature to date, that can potentially lead to obstructive uropathy. We report a case of ureteroinguinal herniation discovered during an inguinal hernia repair in a patient with antenatally ultrasound finding of hydronephrosis. A 2-month-old infant with antenatal left hydronephrosis presented with left inguinal mass. Preoperative ultrasound showed an anechoic tubular image producing a mass effect on the left testicle, with suspected bladder herniation and/or dilated ureter toward the inguinal canal. An open surgical inguinal exploration was performed, where the left inguinal canal revealed a peritoneal sac and sliding of the dilated left ureter behind the sac, with a significant change in diameter, corresponding to the paraperitoneal variant of ureteroinguinal herniation. Ligation of the sac and replacement of the ureter into the retroperitoneum were performed, with improvement in the hydronephrosis observed on the ultrasound 1 month after the intervention. However, 6 months later, hydronephrosis worsening as well as the obstructive pattern observed in the diuretic renogram required removal of the stenotic ureteral segment and reimplantation of the healthy proximal segment in the bladder by open approach (Cohen's reimplantation). Follow-up ultrasound of the renal tract showed no dilatation of the upper renal tract and the renal function tests were normal. Currently, the patient is 2 years old and he remains asymptomatic. In conclusion, s igns of ureteral obstruction such as hydronephrosis in patients with inguinal herniation may suggest the possibility of an ureteroinguinal hernia. Preoperative diagnostic suspicion is essential.
ABSTRACT
INTRODUCTION: The management of acute scrotal swelling can be challenging in neonatal age, with scrotal abscess being great mimickers of testicular torsion. CASE PRESENTATION: We report a 12-day-old previously healthy male infant who presented with 72 h of increasing right-sided scrotal swelling, without fever or irritable behavior. The left testicle was palpable, but the right side was too swollen to palpate a testicle, with absent cremasteric reflex. Biochemical analysis was normal and Doppler sonography demonstrated a hypoechogenic avascular lesion compressing the right testis, without intratesticular flow. Due to these findings, surgical exploration was undertaken on suspicion of potential testicular torsion. Purulent material was encountered and cultured. The testis and epididymis were covered by thick necrotic fibrinous exudate, with no spermatic cord torsion. Gentamicin and vancomycin were begun immediately. The patient remained afebrile and the scrotal induration gradually subsided. Urine and blood cultures were sterile. On the second postoperative day, cultures yielded Escherichia coli sensitive to gentamicin. One-month follow-up testicular ultrasound demonstrated complete inflammation resolution. CONCLUSION: Paratesticular abscess may be considered as the greatest mimicker of testicular neonatal torsion, due to the frequent absence of classical signs of inflammation. Early surgical exploration can be diagnostic and therapeutic and should be performed in these cases.

BACKGROUND: Acellular dermal matrices have long been used for complex abdominal wall closure and, more recently, for ostomy reconstruction. PURPOSE: To describe ostomy reconstruction with acellular flowable dermal matrix (AFDM) in a pediatric patient with a complex abdominal wall defect. CASE REPORT: A 14-year-old female who was diagnosed with unspecific hemorrhagic colitis at age 6 months and who underwent several abdominal surgeries (including total colectomy and terminal ileostomy) reported frequent, severe periostomy skin ulcerations secondary to improper fitting and ostomy bag leakage due to multiple periostomy skin retraction as a result of multiple abdominal scars. Under sedation, 2 small (5 mm) peristomal skin incisions were made, through which dissection and release of dermal scar tissue was performed. Afterwards, AFDM 40 mL was injected subcutaneously until a uniform, flat surface around the ostomy was achieved. The patient was discharged a few hours postoperatively, after verification of proper fit of the ostomy bag with no leakage. At 18-month follow-up, the patient was very satisfied with the result, with fewer ostomy bag changes and improved quality of life. CONCLUSION: This case report indicates that AFDM is a safe and effective minimally invasive technique for ostomy reconstruction, with minimal complications and satisfactory medium-term results.

Background: Neutrophil-to-lymphocyte ratio (NLR) has been recently postulated as an inflammatory biomarker for the diagnosis of vesicoureteral reflux (VUR). The aim of this study is to determine the role of NLR as a predictor of evolution of primary VUR in patients with associated acute pyelonephritis (APN). Methods: A retrospective observational cohort study was performed in patients with APN episodes with associated primary VUR diagnosed between 2013-2020. Patients were divided into two groups according to VUR evolution after APN: group A [spontaneous resolution (SR)] and group B [VUR complications development (CD) during follow-up: new APN or renal function worsening]. Demographic, prenatal, laboratory, microbiological and radiological data were analysed. Sensitivity and specificity for CD of VUR was determined by receiver operating characteristic (ROC) curves. Results: A total of 1,146 episodes of APN were analysed of which 273 patients with APN and associated primary VUR were finally included (median age of 11 months at APN diagnosis). SR of VUR occurred in 169 patients (SR group), while CD were observed in the remaining 104 patients (CD group). No differences in demographic, prenatal, microbiological and radiological features were observed. CD patients had significantly higher levels of leukocytes, neutrophils, NLR, C-reactive protein and creatinine. NLR was the parameter with the highest area under the curve (AUC =0.966) for predicting the development of VUR complications (cut-off point =3.41) with a maximum sensitivity of 92.7% and specificity of 91.1% (P<0.001). Conclusions: NLR may be considered as a simple and cost-effective predictor of clinical outcome of VUR, which may correlate with the increased risk of developing complications of primary VUR after an episode of APN. Therefore, it should be included in the management algorithm for these patients, although future prospective studies are still required to confirm these results.
ABSTRACT
Introducción: El índice neutrófilo-linfocito (INL) es un biomarcador inflamatorio fácilmente calculable a partir del recuento diferencial de leucocitos. El objetivo de este estudio es analizar el papel del INL en la detección de apendicetomías negativas, y comparar su utilidad con otros factores clínicos, ecográficos y de laboratorio previamente descritos. Métodos: Estudio retrospectivo en pacientes menores de 16 años con sospecha de apendicitis aguda intervenidos en nuestra institución entre 2017-2020, que fueron divididos en 2 grupos según hallazgos histológicos apendiculares: Grupo AN: apendicitis negativa; ausencia de inflamación y grupo AP: apendicitis positiva; presencia de inflamación en la pared apendicular. Se analizaron las características demográficas, clínicas, ecográficas y de laboratorio. Resultados: Se incluyeron 1.269 pacientes (1.244 en el grupo AP; 25 en el grupo AN), sin diferencias demográficas entre ellos. Los pacientes del grupo AN presentaron un porcentaje significativamente menor de náuseas y vómitos en comparación con el grupo AP (p<0,001) y menor diámetro ecográfico apendicular (8,1±2,1 vs. 9,7±2,8mm; p<0,001). Los recuentos de leucocitos, neutrófilos e INL fueron significativamente superiores en el grupo AP (p<0,001), así como la proteína C reactiva (18,6 vs. 2,6; p=0,005). El análisis mediante curva ROC mostró que el INL fue el parámetro con mayor AUC (0,879) para el diagnóstico de apendicitis negativa, con un punto de corte de 2,65 con una sensibilidad del 84,2% y una especificidad del 83,8% máximas. Conclusiones: El INL es el parámetro preoperatorio que mejor distingue a los pacientes sin apendicitis aguda. Los valores inferiores a 2,65 deben hacernos sospechar otra causa diferente a la apendicitis. (AU)
Introduction: The neutrophil-to-lymphocyte ratio (NLR) is an inflammatory biomarker that is easily calculated with data from the differential white blood cell count. The aim of our study was to analyse the role of the NLR in the detection of negative appendectomies and to compare its usefulness with other clinical, sonographic and laboratory factors previously described. Methods: We conducted a retrospective study in patients aged less than 16 years who underwent appendectomy in our hospital between 2017 and 2020. We divided patients into 2 groups based on appendiceal histological findings: NA group (negative appendicitis: absence of appendiceal inflammation) and PA group (positive appendicitis: presence of inflammation in any layer of the appendiceal wall). We analysed demographic, clinical, sonographic and laboratory characteristics. Results: We included a total of 1269 patients, 1244 in the PA group and 25 in the NA group, with no differences between groups in demographic characteristics. The proportion of patients that presented with nausea and vomiting was significantly smaller in the NA group compared to the PA group (P<.001), and there were no other differences in symptoms. The appendiceal diameter on ultrasound was significantly smaller in the NA group (8.1±2.1 vs. 9.7±2.8mm; P<.001). The white blood cell and neutrophil counts and the NLR were significantly higher in the PA group (P<.001), as was the level of C-reactive protein (18.6 vs. 2.6; P=.005). The ROC curve analysis revealed that the NLR was the parameter with the highest AUC (0.879) for the diagnosis of negative appendicitis, with a cut-off point of 2.65 for a maximum sensitivity of 84.2% and specificity of 83.8%. Conclusion: The NLR is the preoperative parameter that best discriminates patients without acute appendicitis. Values of less than 2.65 should make clinicians contemplate diagnoses other than appendicitis. (AU)
