Pediatric stricturing Crohn's disease

Crohn's disease (CD) is a chronic inflammatory disease of the digestive tract. The incidence of pediatric CD is increasing and is currently 2.5-11.4 per 100000 world-wide. Notably, approximately 25% of children with CD develop stricturing CD (SCD) that requires intervention. Symptomatic stricturing diseases refractory to pharmacological management frequently require non-pharmacological interventions. Non-pharmacological therapeutic strategies include endoscopic balloon dilatation, stricturoplasty, and surgical resection of the strictured segment. However, strictures tend to recur postoperatively regardless of treatment modality. The lifetime risk of surgery in patients with childhood SCD remains at 50%-90%. Thus, new and emerging strategies, advanced diagnostic tools, and minimally invasive approaches are under investigation to improve the outcomes and overall quality of life of pediatric patients with SCD.

Granular Cell Tumor (Abrikossoff's Tumor) of the Vulva in Childhood

Granular cell tumors (GCTs) (Abrikossoff's tumors) are rare neoplasms derived from Schwann cells. Immunohistochemistry remains the most useful instrument for diagnosing GCTs. Complete surgical excision has been demonstrated to be curative for benign lesions. However, long-term follow-up in these patients is strongly recommended.

Management of pleural effusion and empyema in a third-level pediatric surgical center

BACKGROUND

Pleural effusion and empyema are frequent complications of acute bacterial pneumonia in children. To date, evidence regarding the optimal treatment of this condition is limited in the literature.

METHODS

Patients with pleural effusion and empyema admitted at our Department of Pediatric Surgery over the last ten years were enrolled in this retrospective study, and successively compared with the clinical charts of patients treated before the introduction of a new diagnostic and therapeutic algorithm. In particular, primary outcomes investigated between pre- and postalgorithm period were the use of diagnostic tools and antibiotics, the need for additional therapeutic approaches, complications, and the length of stay.

RESULTS

After the introduction of the new algorithm there were a decrease in the use of chest radiography for re-evaluation (100% vs. 79%, P=0.003), a more focused use of computed tomography (68% vs. 15%, P=0.001), and a decrease in the use of a second computed tomography (18% vs. 3%, P=0.07); in favor of an increase in the use of the ultrasound scan (40% vs. 100%, P=0.001). There was also a shift from the use of chest tube drainage alone to the use of drainage for urokinase administration (50% vs. 92.3%, P=0.001), and a statistically significant decrease in the need for video-assisted thoracoscopic surgery (25% vs. 7.7%, P=0.001).

CONCLUSIONS

The introduction of a diagnostic and therapeutic algorithm for the management of pediatric pleural effusion and empyema has notably resulted in a decrease in the utilization of radiography and computed tomography and an increase in the use of ultrasonography, reducing unnecessary radiation exposure in children and overall costs.

Clinical characteristics of pediatric inpatients infected with the SARS-CoV-2 Omicron variant-a retrospective observational cohort study

Background

The children infected with the Omicron variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are at risk of progressing to severe disease. Clinical characteristics treatment measures and prognosis of these special age group of patients have not been completely understood which necessitate more researches. This study sought to analyze the clinical characteristics of children infected with the Omicron variant to provide evidences for the prevention, diagnosis and treatment of the Omicron variant infection in children.

Methods

The subjects of this study included children hospitalized for the Omicron variant at Tianjin Binhai Hospital in November 2022. The data were collected from the electronic medical record system, and the clinical characteristics of the children were analyzed. The primary endpoints included the clinical presentation, laboratory tests, virological characteristics, treatment regimen, and clinical prognosis of the patients.

Results

A total of 49 patients were enrolled, of whom 32 (65.3%) were male. The patients had a median age of 10 (interquartile range, 6-11) years, and 34.7% of the patients received 2 or more coronavirus disease 2019 (COVID-19) vaccines. The main clinical manifestations of the patients were fever (79.6%) and cough (24.5%), with a maximum temperature of 42 ℃ and a median temperature of 39 (interquartile range, 38.4-39) ℃. The proportions of neutrophils and C-reactive protein were elevated by 50.0% and 25.0%, respectively. The total percentages of white blood cells and thrombocytopenia were 12.5% and 6.3%, respectively. D-dimer was examined in 6 cases, and was elevated to 1.77 μg/mL in 1 case (16.7%), and normal in 5 cases. The liver function, kidney function, and coagulation of 9 (100%) patients were all normal. After the anti-virus, anti-inflammatory response, antipyretic, and traditional Chinese medicine treatments, all the children were cured and discharged from the hospital. There were no severe cases.

Conclusions

The main manifestations of children infected with the SARS-CoV-2 Omicron variant were fever and cough. Some children had a high fever, nasal congestion, runny nose, gastrointestinal symptoms, and rash. A proportion of 12.5% of patients have a white blood cell count less than 4×109/L, and 6.3% have thrombocytopenia. The prognosis of the child was favorable after treatment with antiviral, antipyretic, and traditional Chinese medicine.

Informed consent in minor and intermediate pediatric elective surgery: results of an in-house questionnaire

Background

The aim of this study was to evaluate the quality of our surgical informed consent and parents'/guardians' late recall of surgical procedures and risks of elective day surgery after pre-operative interview with surgeons.

Methods

All parents/guardians of patients <18 years of age undergoing minor and intermediate elective procedures from January 15th to September 1st, 2022, were prospectively enrolled in the study. Before discharge, parents/guardians were asked to complete an in-house questionnaire regarding the duration of the consent procedure, duration of the interview, quality of the informative handouts, and their ability to recall the type of disease, type of surgical procedure, and surgical risks.

Results

One hundred and two questionnaires were returned. In all cases, informed consent was obtained between 24 and 72 h prior to surgery. The following responses were collected: 98/102 (96%) parents/guardians reported that the duration of the consent process was adequate; 95/102 (93%) reported that the handouts were fully informative, and 7/102 (7%) reported that they were partially informative regarding explanation of the disease and surgical procedure; regarding complications, 93/102 (91%) perceived the handouts to be fully/partially informative, while 4/102 (4%) perceived the handouts to be poorly/non-informative, and 5/102 (5%) did not provide a response; 94/102 (92%) stated that they remembered the pathology, but only 87/94 (93%) recalled it correctly; 90/102 (88%) stated that they remembered the type of procedure, but only 76/90 (84%) recalled it correctly; and 53/102 (52%) stated that they remembered the surgical risks, but only 20/53 (38%) could recall more than one complication.

Conclusions

Late recall of surgical complications by parents was poor despite the high perceived quality of the surgical risk handouts and medical interview. Implementation of expedient methods may improve overall comprehension and satisfaction of parents/guardians regarding the IC process. Further, more efforts should be made to develop standardized guidelines for an optimal IC process.

Robotic-assisted surgery in pediatrics: what is evidence-based?-a literature review

BACKGROUND AND OBJECTIVE

The use of robotic-assisted surgery (RAS) has increased more slowly in pediatrics than in the adult population. Despite the many advantages of robotic instruments, the da Vinci Surgical System (Intuitive Surgical, Sunnyvale, CA, USA) still presents some limitations for use in pediatric surgery. This study aims to examine evidence-based indications for RAS in the different fields of pediatric surgery according to the published literature.

METHODS

A database search (MEDLINE, Scopus, Web of Science) was performed to identify articles covering any aspect of RAS in the pediatric population. Using Boolean operators AND/OR, all possible combinations of the following search terms were used: robotic surgery, pediatrics, neonatal surgery, thoracic surgery, abdominal surgery, urologic surgery, hepatobiliary surgery, and surgical oncology. The selection criteria were limited to the English language, pediatric patients (under 18 years of age), and articles published after 2010.

KEY CONTENT AND FINDINGS

A total of 239 abstracts were reviewed. Of these, 10 published articles met the purposes of our study with the highest level of evidence and therefore were analyzed. Notably, most of the articles included in this review reported evidence-based indications in urological surgery.

CONCLUSIONS

According to this study, the exclusive indications for RAS in the pediatric population are pyeloplasty for ureteropelvic junction obstruction in older children and ureteral reimplantation according to the Lich-Gregoire technique in selected cases for the need to access the pelvis with a narrow anatomical and working space. All other indications for RAS in pediatric surgery are still under discussion to date, and cannot be supported by papers with a high level of evidence. However, RAS is certainly a promising technology. Further evidence is strongly encouraged in the future.

Oxygen-enriched oleic matrix (NovoX) for wound healing in pediatric patients undergoing open surgical treatment for pilonidal disease: Preliminary experience

INTRODUCTION

Pilonidal disease (PD) is a common infectious and inflammatory condition affecting the gluteal cleft and sacrococcygeal region. The optimal treatment for PD remains controversial. While the open technique reduces the number of relapses compared to minimally invasive approaches, it is associated with a longer healing time. Reactive oxygen species are a key part of the normal wound-healing process. Herein, we reported our preliminary experience using a new oxygen-enriched oil-based product called NovoX for wound healing after open surgery for PD.

MATERIALS AND METHODS

We used a new oxygen-enriched product for wound healing in three pediatric patients undergoing open surgical repair for PD between December 2021 and April 2022. During postoperative follow-up, healing time and the aesthetic result were evaluated.

RESULTS

Our preliminary study included three patients with chronic PD. The average follow-up time was 5 weeks, corresponding to the end of the healing process and the resumption of normal daily activities. Only one mild complication occurred during the study period. No short-term side effects were reported. The cosmetic result was reported as satisfactory.

CONCLUSION

NovoX is easy to apply, safe, and effective for treating pediatric patients undergoing open surgical treatment for PD, leading to slightly faster wound healing with good aesthetic outcomes.

Case Report: Simil-Appendicitis Presentation May Precede Cardiac Involvement in MIS-C Patient

INTRODUCTION

Multisystem inflammatory syndrome in children (MIS-C) is a new clinical entity characterized by a systemic hyperinflammation triggered by SARS-CoV-2 infection in children and adolescents. This condition could potentially involve all organs with main complications concerning cardiovascular system. Despite up to 90% of patients complain gastrointestinal symptoms (nausea, vomit, and diarrhea), a presentation mimicking acute appendicitis has rarely been reported, and can be the presenting feature of the disease, potentially leading to misdiagnosis and delayed treatment.

CASE DESCRIPTION

A 15-year-old boy presented to the Emergency Department for a 2-day history of fever, vomiting, and mild abdominal pain. One month before, the patient complained ageusia and anosmia while his mother tested positive for Sars-CoV2 nasopharyngeal swab. At admission, laboratory tests showed leukocytosis with lymphopenia and elevation of inflammatory markers, while cardiac enzymes, electrocardiogram and echocardiography were unremarkable. An abdominal ultrasound displayed a thickening of terminal ileus and cecum with ascites. Because of the worsening abdominal pain and a physical examination suggestive of acute appendicitis, a laparoscopy was performed but no surgical condition was found. After surgery, fever and generalized malaise persisted, so a cardiac evaluation was repeated, showing a relevant increase in inflammatory markers and cardiac enzymes. Electrocardiogram demonstrated a QTc prolongation with mild decrease in left ventricular ejection fraction at echocardiogram. A MIS-C was diagnosed and intravenous immunoglobulin along with a steroid treatment started. After 36 h, the patient presented a complete clinical recovery with fever cessation. Cardiac anomalies normalized in 3 weeks.

CONCLUSION

MIS-C has been defined as a systemic inflammation, involving at least two organs, after a previous SARS-CoV2 infection in children and adolescents. Physicians should be aware that while gastrointestinal manifestations are common, a pseudo appendicitis presentation may also occur, leading to misdiagnosis and delayed treatment. This report suggests that in patients with symptoms suggestive of an acute appendicitis, the presence of lymphopenia, hypoalbuminemia and ultrasound images of terminal ileus inflammation, should raise the suspect for MIS-C even without initial overt signs of cardiac involvement.

Management of Primary Spontaneous Pneumothorax in a Third-Level Pediatric Surgical Center: A Retrospective Study

INTRODUCTION

The management of primary spontaneous pneumothorax (PSP) in pediatrics remains controversial. The aim of this study was to investigate the risk of recurrence after non-surgical treatment vs. surgery, the difference in the length of stay (LOS) between various treatment options, and the role of computed tomography (CT) in the management of PSP.

MATERIALS AND METHODS

We retrospectively reviewed patients admitted to our Pediatric Surgery Unit for an episode of PSP between June 2009 and July 2020. Medical records including clinical presentation at admission, diagnostics, treatments, complications, and LOS were collected.

RESULTS

Twenty-three patients (22 males and 1 female) were included in this study. Median age was 15.65 (range 9-18). Chest X-rays were performed in all patients and showed 5 small (22%) and 18 large (78%) PSP. Chest drain was used for large PSP (≥2 cm) if the patient was clinically unstable. Eleven patients (48%) were managed non-operatively with observation alone and a recurrence rate of 18%, chest drain was used in 11 patients with a recurrence rate of 36%, and surgery was deemed necessary as a first treatment choice in one case. Six patients (27%) had an episode of relapse after non-operative management or chest drain placement. Following surgery, a relapse occurred in 2 of the 6 patients. Chest drain insertion was associated with a longer LOS than observation alone (6.36 vs. 2.4 days), and surgery resulted in a longer LOS than other types of treatment (P = 0.001).

CONCLUSION

According to our experience, small PSP or clinically stable larger PSP can be treated conservatively with observation alone. Operative management should be taken into consideration in children with large symptomatic PSP, persistent air leak, and/or relapse after chest drain insertion.

Epididymal cyst in children

The terms "epididymal cyst" and "spermatocele" are commonly used to describe the same entity, but, conversely, they are slightly different. Epididymal cyst is a benign mass, and it is more common than previously thought in prepubertal age. Pathogenic mechanisms for epididymal cyst have not been fully clarified yet, even if epididymal cysts have been reported in association with other malformations of the urinary tract or complex syndromes. Epididymal cyst is easily characterized and differentiated from spermatocele using ultrasound imaging. Conservative management constitutes the treatment of choice in the majority of cases, and surgery is recommended only in selected cases. Conclusion: To date, a review on epididymal cyst in childhood is lacking in the literature. Herein, an overview of knowledge about epididymal cyst in children has been carried out with particular attention to differential diagnosis, proper management, and practice guidelines for caregivers of children who may present with an epididymal cyst. What is Known: • Epididymal cyst is a benign sac in the testicles which is usually asymptomatic. • Epididymal cyst is easily diagnosed by ultrasound scans, and it is considered a self-limiting disease in the majority of cases. What is New: • Insight on differential diagnosis between epididymal cyst and spermatocele. • Valuable knowledge on the best management strategy for epididymal cyst and on practice guidelines for parents of children presenting with epididymal cyst.

Pyogenic granuloma arising within capillary malformations in children: A case report and literature review

Pyogenic granuloma (PG) is an acquired benign vascular hyperplasia. Even though PG is not so rare, its etiology is still unclear. Assuredly, an association between vascular anomalies and PG is an extremely rare finding, and a proper management of these cases is not well standardized to date. Herein, we report our experience with a giant PG arising spontaneously within a port-wine stain of the thorax. Previous cases reported in the pediatric literature and strategies of treatment are also discussed.

Glans ischemia after circumcision in children: Two case reports

BACKGROUND

Circumcision refers to the removal of the skin covering the tip of the penis and is one of the most common surgical procedures performed in childhood. Even though circumcision is a well-standardized operation, several minor and major complications may be experienced by paediatric surgeons. Glans ischemia (GI) has been widely reported in the paediatric literature as a complication following circumcision. Nonetheless, etiopathogenesis of GI is not well defined and management guidelines are lacking.

CASE SUMMARY

We describe our experience with this rare and scary complication using subcutaneous enoxaparin alone or in association with a topical vasodilator.

CONCLUSION

Hypothetical causes and different management strategies are discussed.

Lipoblastoma as a cause of secondary omental torsion in children: report of the first case

Acute abdominal pain remains a major diagnostic challenge to date. Omental torsion is an infrequent cause of abdominal pain in children, which usually presents with non-specific symptoms. Herein, we report a case of persistent abdominal pain after a minor abdominal trauma. A solid mass was found in the lower abdomen at ultrasound imaging evaluation. Surgical exploration demonstrated an omental torsion secondary to a rare neoplasm of childhood.

Esophageal Stricture as a Complication After Scald Injury in Children

Burn injuries are distressful and shocking events, which can lead to noteworthy sequelae on metabolic markers and organs. Such traumatic accidents do occur every so often in both adult and pediatric populations, requiring prompt and adequate treatments. Notably, scald injuries occur due to direct contact with hot liquids and these are the most common cause of burns in early childhood. Herein, we report on an 18-month-old boy admitted to our pediatric surgery unit for an extensive scald injury, who has experienced an unusual esophageal stricture following the traumatic event.

Risk Factors for Surgical Site Infection in Neonates: A Systematic Review of the Literature and Meta-Analysis

Purpose: Surgical site infections (SSI) contribute to postoperative morbidity and mortality in children. Our aim was to evaluate the prevalence and identify risk factors for SSI in neonates. Methods: Using a defined strategy, three investigators searched articles on neonatal SSI published since 2000. Studies on neonates and/or patients admitted to neonatal intensive care unit following cervical/thoracic/abdominal surgery were included. Risk factors were identified from comparative studies. Meta-analysis was conducted according to PRISMA guidelines using RevMan 5.3. Data are (mean ± SD) prevalence. Results: Systematic review-of 885 abstracts screened, 48 studies (27,760 neonates) were included. The incidence of SSI was 5.6% (1,564 patients). SSI was more frequent in males (61.8%), premature babies (77.4%), and following gastrointestinal surgery (95.4%). Meta-analysis-10 comparative studies (16,442 neonates; 946 SSI 5.7%) showed that predictive factors for SSI development were gestational age, birth weight, age at surgery, length of surgical procedure, number of procedure per patient, length of preoperative hospital stay, and preoperative sepsis. Conversely, preoperative antibiotic use was not significantly associated with development of SSI. Conclusions: Younger neonates and those undergoing abdominal procedures are at higher risk for SSI. Given the lack of evidence-based literature, prospective studies may help determine the risk factors for SSI in neonates.

Pediatric Intestinal Rehabilitation and Transplantation Registry: Initial Report from a European Collaborative Registry

INTRODUCTION

 Short bowel syndrome (SBS) is the main cause of intestinal failure (IF) in the pediatric population. To promote the standardization of care of these patients, the registry of Pediatric Intestinal Rehabilitation and Transplantation (PIRAT) has been established. The aim of this study is to describe patients with IF using PIRAT database.

MATERIALS AND METHODS

 Data from two tertiary care European referral Centers registered in PIRAT (https://www.studeon.eu/pirat) were analyzed (1994-2015). Neonatal SBS-related IF was defined as need for parenteral nutrition (PN) to sustain life and growth for more than 75 days, after extensive bowel resection during neonatal period. Data included patient demographics, disease at birth, residual small intestine, and intestinal autonomy (PN on/off).

RESULTS

 In this study, 114 children with SBS-related IF were identified (male 60%). Median gestational age was 35.3 weeks (interquartile range [IQR]: 33.0-38.0); median birth weight was 2,440 g (IQR: 1,700-2,990). The main causes of SBS were intestinal atresia in 31 (27%), midgut volvulus in 29 (25%), necrotizing enterocolitis in 23 (20%), and gastroschisis in 12 (11%). Nine (7.9%) patients died on PN (six sepsis, two IF-associated liver disease, and one multiorgan failure). Median residual small bowel length was 46 cm (IQR: 13.0-92.5). Ileocecal valve was resected in 48 patients (42%). Intestinal autonomy was achieved in 68% patients.

CONCLUSION

 We present the web-based registry PIRAT and the first results of patients with IF registered from two European Centers. PIRAT could give the opportunity to create a dedicated international network (IF-net) to standardize, improve, and spread the therapeutic paths for the rare and heterogeneous condition of SBS-related IF.

Pathogenetic and Prognostic Factors for Neonatal Gastric Perforation: Personal Experience and Systematic Review of the Literature

INTRODUCTION

Neonatal gastric perforation (NGP) is a rare entity. Our aim was to report our experience and review the recent literature to characterize NGP, describe associated factors, and define prognostic factors.

MATERIALS AND METHODS

Retrospective review of all consecutive patients with NGP treated between June 2009 and December 2017 in a third level pediatric hospital. In addition, a systematic review of Medline and Scopus database was performed using a defined strategy. All articles referring to NGP published between 2005 and 2017 were retrieved. Variables considered: prematurity (<37 weeks gestation), birth weight (BW), Apgar score, prenatal complications, age at diagnosis, bag ventilation, pathogenetic events, site of perforation, treatment of perforation, sepsis, and outcome. Mann-Whitney or Fisher's test were used as appropriate. Results are median (range) or prevalence.

RESULTS

Between 2009 and 2016 we treated 8 consecutive patients for NGP and 199 further cases were retrieved from the systematic review (total of 207 patients). Overall survival was 73%. Most frequently reported pathogenesis: iatrogenic (20 patients), hypoxic/ischemic or infection stress (13 patients), duodenal/jejunal obstruction (11 patients), drugs (11 patients), esophageal atresia (10 patients). 60% patients had only primary repair of the perforation as gastric surgery. Sepsis developed in 56 patients (34%).

CONCLUSION

Although the pathogenesis of NGP is pleomorphic, prematurity and low BWs are frequent in these patients. Reviewing our experience and the available literature, none of the variables considered, but sepsis was associated with mortality.

Fire in the Operating Room During Hypospadias Repair

Fire in the operating room (OR) is a very distressful and shocking occurrence with potential dramatic consequences. Despite safety rules and rigorous recommendations, such unintentional events do occur every so often. Notably, the vast majority of cases have been reported in the adult population, with very few pediatric cases described to date. Herein, we report on a 16-month-old boy undergoing reconstructive surgery for penoscrotal hypospadias, who experienced an OR fire most likely related to the use of alcohol-based solution ignited by monopolar electrocautery.

Plaque-Like Myofibroblastic Tumor of Infancy: A New Case Report and Literature Review

Plaque-like myofibroblastic tumor of infancy is a rare entity, with only a few reports described in the literature. Herein we present a new case of a nodular plaque-like lesion of the left lower back in an 18-month-old boy. The lesion might initially be thought to be a dermatofibroma, but the overall characteristics suggested the diagnosis of plaque-like myofibroblastic tumor of infancy. We also provide a summary of previous reports in the literature about this exceptional tumor.

The THUNDERBEAT system for tissue dissection and vascular control in laparoscopic splenectomy

The advent of new energy sources for hemostasis has greatly facilitated advanced laparoscopic procedures. We describe a straightforward technique of laparoscopic splenectomy (LS) accomplished using the THUNDERBEAT™ system (TS) (Olympus Medical Systems Corp., Tokyo, Japan) as the sole means of tissue dissection and hemostasis in two patients aged 19 and 6 years, respectively. The specimens were removed intact via a Pfannenstiel incision. Total operative time was 165 and 150 min, and length of hospital stay was three and 4 d, respectively. The TS is an appealing and reliable alternative to currently available energy devices, allowing fast dissection and secure hemostasis during laparoscopic splenectomy.

Periungual myiasis caused by wohlfahrtia magnifica mimicking an ingrown toenail

Myiasis is the infestation of organs and tissues of human being or other vertebrate animals with dipterous larvae. Myiasis is generally rare in humans, especially in children. We present the first case of periungual myiasis by Wohlfahrtia magnifica in a 5-year-old female. Wohlfahrtia magnifica is an obligatory parasite, which has been described as cause of ophthalmomyiasis, otomyiasis, oral myiasis, vulvar myiasis and wound myiasis. Treatment of myiasis and ingrown toenail is generally non-operative although both entities can be serious and/or non-responsive to conservative therapy.

Hepatoblastoma in a 14 month-old female

Hepatoblastoma (HB) is the most common malignant liver tumor in children. Complete surgical resection is the best treatment choice with a good prognosis in most cases. We present the case of a 14 month-old female patient was admitted to the pediatric surgery unit due to an abdominal mass localized in the right upper quadrant. The diagnosis retained was hepatoblastoma, so the patient underwent preoperative chemotherapy. The final size of the tumor permitted a complete surgical resection through a right subcostal incision enlarged to the left. Hepatoblastoma is the most common malignant liver tumor in children, more frequent in male than in female and typically presenting before 3 years of age as an abdominal mass found accidentally. Recent treatment strategies, consisting of chemotherapy combined with extensive surgery and in extreme cases liver transplantation, have improved the prognosis during the last years although HB's etiology and management are still subjects of debate.

Recurrent tethered cord: radiological investigation and management

INTRODUCTION

Recurrent tethered cord (RTC) is almost the rule after the repair of myelomeningocele and quite frequent after the repair of lipomyelomeningocele, resulting from the adhesions of the placode within a too narrow spinal canal. About one-third of patients with myelomeningocele and 10 % of those with spinal lipoma develop symptomatic RTC, mainly caused by the ischemic-metabolic injuries due to the cord stretching. The goal of this review is to provide information about the pathophysiology, the radiological picture, and the management of RTV according to the pertinent literature and the authors' experience.

RADIOLOGICAL INVESTIGATION

The magnetic resonance imaging (MRI) picture is characterized by a low position of the conus and by tethering of the spinal cord to the subcutaneous scar or to the inner surface of the spinal canal. The radiological work-up always includes brain MRI, to rule out other possible causes of late neurological deterioration (as shunt malfunction), and MRI of the whole spinal cord, to detect possible associated lesions (syringomyelia, dermoids, etc.). X-rays and/or computed tomography scan of the spine is required for the assessment of scoliosis or other bony malformations.

MANAGEMENT

The surgical treatment is planned after a multidisciplinary neurological, urological, orthopedic, physiatric, and radiological evaluation. The surgical detethering is carried out cautiously, possibly with electrophysiological intraoperative monitoring. Surgery ensures improvement or stability of the clinical picture in 70-80 % of cases, the remaining 20-30 % of patients needing multiple operations for their recovery. Complications may affect up to one-third of operated patients, being mainly represented by CSF leak, pseudomeningocele, and shunt malfunction.
