Uncommon Complication of Pediatric Umbilical Hernia-Spontaneous Evisceration: Case Report and Literature Review.

The umbilical hernia is common in children. Most of the cases have a spontaneous regression around the age of 3 years. Complications are very rare, and thus surgery is not routinely indicated before the age of 3 years. We report an exceptional case of spontaneous rupture of an umbilical hernia with emphasis on the management of this rare complication and a literature review of similar cases.

Management of lower urinary tract fibroepithelial polyps in children.

INTRODUCTION: Fibroepithelial polyps (FEP) of the lower urinary tract are relatively common in adults but rare in children, with fewer than 250 cases reported in the literature to date. OBJECTIVE: The aim of this study was to address the experience of FEP management in children. STUDY DESIGN: A retrospective multicenter review was undertaken in children with defined FEP of the lower urinary tract managed between 2008 and 2018. The data at 18 pediatric surgery centers were collected. Their demographic, radiological, surgical, and pathological information were reviewed. RESULTS: A total of 33 children (26 boys; 7 girls) were treated for FEP of the lower urinary tract at 13 centers. The most common presentation was urinary outflow as hematuria (41%), acute urinary retention (25%), dysuria (19%), or urinary infections (28%). A prenatal diagnosis was made for three patients with hydronephrosis. Almost all of the children (94%) underwent ultrasound imaging of the urinary tract as the first diagnostic examination, 23 (70%) of them also either had an MRI (15%), cystourethrography (25%), computerized tomography (6%), or cystoscopy (45%). Two of these children (6%) had a biopsy prior to the surgery. The median preoperative delay was 7.52 (range: 1-48) months. Most of the patients were treated endoscopically, although four (12.1%) had open surgery and two (6.1%) had an additional incision for specimen extraction. The median hospital stay was 1.5 (range: 1-10) days. There were no recurrences and no complications after a median follow-up of 13 (range: 1-34) months. DISCUSSION: The main limitation of our study is the retrospective design, although it is the largest one for this pathology. CONCLUSION: This series supports sonography as the most suitable diagnosis tool before endoscopy to confirm the diagnosis and to perform the resection for most FEP in children. This report confirms the recognized benign nature in the absence of recurrences. LEVEL OF EVIDENCE: Level V.

Long-term prognosis of Salter-Harris type 2 injuries of the distal femoral physis.

The objective of this study was to assess long-term sequelae of Salter-Harris type 2 injuries on growth of the distal femoral physis. A retrospective study of 20 patients with Salter-Harris type 2 distal femoral injuries, who were managed between 1994 and 2003, was carried out. The average period of follow-up was 4 years and 2 months. Mean age of fracture was 11 years (range 8-15 years). We classified radiologically these fractures into three types according to initial displacement on anteroposterior and lateral radiographs (type 1=less than 2 mm; type 2=more than 2 mm, contact between fragments; type 3=no contact). Further subdivision into A and B was made according to the absence or presence of metaphyseal comminution. Clinical and radiological outcomes were evaluated at latest follow-up. Two patients with type 1 injuries were treated conservatively, with no complication. All type 2 and 3 fractures (18) were reduced under general anesthesia. At latest follow-up, 14 patients (70%) sustained a complication due to either epiphysiodesis (12), femoral over-lengthening (1) or associated loss of knee motion (5). Seven out of the 12 epiphysiodeses were initial type B injuries. All type 3 fractures ended with complications. The prognosis of these fractures, often caused by a high-energy trauma, can be severe. Additional subdivision of Salter-Harris type 2 distal femoral physeal injuries is proposed to warn the clinician on specific fracture patterns with higher complication risk. Greater awareness of the numerous growth problems that may occur is needed in type 2B, in which the germinal layer of the physeal cells is damaged.

Percutaneous retrograde endovascular occlusion for pediatric varicocele.

BACKGROUND/PURPOSE: The aim of this study was to assess whether percutaneous retrograde endovascular occlusion (PREVO) is effective and safe for the treatment of varicocele in pediatric patients. METHODS: We retrospectively studied 71 children who underwent PREVO for left-sided varicocele. The primary outcome was the proportion of varicocele-free patients 6 months after PREVO as assessed by ultrasonography. RESULTS: Seventy-one boys with left-sided grade III varicocele underwent PREVO at a mean age of 13.2 years. PREVO was performed under local anesthesia in all boys but 2, who required general anesthesia. The procedure was technically feasible in 68 (96%) patients. In the remaining 3 patients, the internal spermatic vein could not be catheterized. Minor short-term complications occurred in 6 patients and resolved fully. No major complications or deaths were recorded. The proportion of varicocele-free patients 6 months after PREVO was 93% (66/71) overall and 97% (66/68) in the patients whose PREVO procedure was feasible. No clinical recurrence was observed during the mean follow-up of 17.5 months. CONCLUSIONS: Percutaneous retrograde endovascular occlusion is an effective minimally invasive approach for varicocele treatment in pediatric patients. It can be safely performed on an outpatient basis under local anesthesia.
