RESUMEN

BACKGROUND: Dysplasia, carcinoma in situ, and other malignant transformation or premalignant/malignant histopathology (PMMH) seem uncommon in pediatric choledochal cyst (CC). A literature review and the authors' experience are presented. METHODS: All reports about PMMH in CC patients 15 years old or younger published in English and all cases of PMMH in specimens excised from CC patients 15 years old or younger by the authors were reviewed. RESULTS: Of 20 published reports, PMMH was adenocarcinoma (n = 4), sarcoma (n = 4), and dysplasia (n = 12). Treatment for malignancies was primary pancreaticoduodenectomy (PD; n = 2) or cyst excision/hepaticojejunostomy (Ex/HJ; n = 6). Outcomes at the time of writing for malignancies: 2 deaths, 4 survivors after follow-up of 2 years, and 2 lost to follow-up. No dysplasia case has undergone malignant transformation. The authors have experienced 7 cases of PMMH; adenocarcinoma in situ (AIS; n = 1) and dysplasia (n = 6). CONCLUSIONS: The present study identified the youngest cases of AIS and dysplasia from specimens excised when they were 3 years old and 4 months old, respectively. Both are published for the first time as evidence that PMMH can complicate CC in young patients. Long-term protocolized postoperative follow-up is mandatory when PMMH is diagnosed in pediatric CC.

RESUMEN

PURPOSE: To evaluate common hepatic duct just distal to the HE anastomosis (d-CHD) prospectively for mucosal damage, inflammation, fibrosis, dysplasia, carcinoma in situ, malignant transformation, effects of serum amylase, and symptoms at presentation in CC cases ranging from children to adults. METHODS: Cross-sections of d-CHD obtained at cyst excision 2018-2023 from 65 CC patients; 40 children (< 15 years old), 25 adults (≥ 15) were examined with hematoxylin and eosin, Ki-67, S100P, IMP3, p53, and Masson's trichrome to determine an inflammation score (IS), fibrosis score (FS), and damaged mucosa rate (DMR; damaged mucosa expressed as a percentage of the internal circumference). RESULTS: Mean age at cyst excision ("age") was 18.2 years (range: 3 months-74 years). Significant inverse correlations were found for age and DMR (p = 0.002), age and IS (p = 0.011), and age and Ki-67 (p = 0.01). FS did not correlate with age (p = 0.32) despite significantly increased IS in children. Dysplasia was identified in a 4-month-old girl with cystic CC. Serum amylase was elevated in high DMR subjects. CONCLUSIONS: High DMR, high IS, and evidence of dysplasia in pediatric CC suggest children are at risk for serious sequelae best managed by precise histopathology, protocolized follow-up, and awareness that premalignant histopathology can arise in infancy.

RESUMEN

BACKGROUND: Testicular appendage torsion (TAT) is a medical emergency that presents as an acute scrotum, usually in children and preadolescents. In previous reports of TAT, most cases have been treated conservatively, but some necessitate surgical treatment. Our aim was to examine the incidence, clinical examination findings, etiology, and treatment of TAT. METHODS: We retrospectively reviewed records of all patients with TAT (aged ≤15 years) treated at the Juntendo University Urayasu Hospital between January 2012 and September 2020. Surgical treatment was performed when a diagnosis of testicular torsion could not be completely ruled out or if pain recurred after conservative treatment. Patients with a hard scrotum or scrotal erythema were hospitalized for conservative treatment. Data regarding age, diagnosis, blood test results, and clinical findings were analyzed. RESULTS: Among 101 boys with TAT, the median age was 10 years. The incidence of TAT varied significantly according to age and was highest among patients aged 8-11 years. Sixty-seven boys (66.3%) underwent inpatient surgical treatment, 10 boys (9.9%) received inpatient conservative treatment, and 24 boys (23.8%) received outpatient conservative treatment. The median duration of hospitalization was significantly shorter among those who underwent surgery (2.0 days) than among those who received inpatient conservative treatment group (3.5 days). CONCLUSIONS: Operations were short, uncomplicated, and safe; they shortened the hospital stay; and they would certainly prevent recurrence of TAT and testicular torsion on one side. Furthermore, we recommended that TAT patients presenting with signs of severe inflammation, such as hard scrotum or scrotal erythema, receive early surgical treatment to minimize duration of hospitalization.

RESUMEN

INTRODUCTION: Testicular torsion (TT), as per the reported incidences in children and preadolescents, is an emergency medical condition that requires prompt surgical treatment. In cases of TT, early and accurate diagnosis of acute scrotum (AS) is important to preserve testicular fertility. In this study, the authors aimed to determine the incidence, clinical examination, etiology, clinical predictors, and treatment of patients with AS and TT. MATERIAL AND METHODS: The authors retrospectively reviewed all children (age, ≤15 years) with AS who visited their hospital between January 2012 and June 2019. Data on age and diagnosis, clinical findings, mode of treatment, and blood examination results were collected. RESULTS: The authors examined 165 children aged between 0 days and 15 years (mean age, 9.4 years). Final diagnosis identified 72 patients with torsion of the appendix testis, 44 patients with epididymitis, and 38 patients with TT. Testes were salvaged in 23 of the 38 patients with TT (60.5%). Statistically significant variables revealed that the risk factors of TT were age (older than 12 years), white blood cell (WBC) count (>12,000 cells/mm3), and laterality (left side). The level of C-reactive protein (CRP), duration of symptoms, and degree of torsion were significantly higher in the non-salvageable testis group than in the salvageable testis group. Furthermore, the significant predictive factor for non-salvageable testis was the level of CRP >1.0 mg/dl. CONCLUSION: The study results indicates that age, WBC count, and laterality are key factors to distinguish TT from AS. Salvageability largely depended on the duration of symptoms and the degree of TT. The salvage rate of the testis can be improved by educating pediatricians, parents, patients, and medical staff about the early diagnosis and treatment of torsion.
