The Fisher Technique for Correction of Penile Torsion in Children: Who Are the Candidates?

To report our experience in the treatment of penile torsion with a special reference to the Fisher technique. We reviewed 30 cases of congenital penile torsion treated from 2009 to 2015 in a single center. Sixteen patients presented a moderate rotation of 45°-90° and 14 had a severe rotation with an angle greater than 90°. Chordee was present in 17 cases and distal glanular hypospadias in 15 cases. Median age at surgery was 10 months. In 14 cases, degloving along with skin realignment, alone, allowed correction of the torsion. In 16 cases, the Dartos flap (Fisher technique) was used. Out of the 30 patients, 29 had a good result, with a complete correction of the torsion. Only 1 patient had a residual torsion of 30°. Complications were minor and consisted of skin excess in 11 patients; 1 single case needed to be reoperated for that skin complication. The need for the Dartos flap procedure was significantly correlated to the degree of torsion (P = .001): it was used in 4 out of 16 patients (25%) with a torsion of less than 90°, and in 12 out of 14 patients (86%) with a torsion of 90° or more. Most of penile rotations less than 90° can be corrected by skin degloving and realignment. The Fisher technique is a simple and safe procedure for correction of persistent rotation after skin degloving; such cases have usually a penile rotation greater than 90°.

No. 341-Diagnosis and Management of Adnexal Torsion in Children, Adolescents, and Adults.

To review the evidence and provide recommendations on the diagnosis and management of adnexal torsion in children, adolescents, and women. Elements evaluated include the risk factors, diagnostic accuracy, management options, and outcomes of adnexal torsion. Published literature was retrieved through searches of MEDLINE, Embase, CINAHL, and the Cochrane Library using appropriate controlled vocabulary and key words ("adnexal torsion," "ovarian torsion"). Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies. Searches were updated on a regular basis and new material incorporated in the guideline to December 2014. Grey (unpublished) literature was identified through searching the websites of health technology assessment and related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies. The evidence obtained was reviewed and evaluated by the Canadian Paediatric and Adolescent Gynaecology and Obstetrics Committee of the Society of Obstetricians and Gynaecologists of Canada (SOGC) under the leadership of the principal authors. Recommendations were made according to guidelines developed by the Canadian Task Force on the Periodic Health Examination. Guideline implementation should assist the practitioner in developing an optimal approach to the diagnosis and management of adnexal torsion while minimizing harm and improving patient outcomes. These guidelines have been reviewed and approved by the Gynaecology Committee of the SOGC and approved by the council of the SOGC. The Society of Obstetricians and Gynaecologists of Canada SUMMARY STATEMENTS: RECOMMENDATIONS.

Ultrasonographic Assessment of Testicular Viability Using Heterogeneity Levels in Torsed Testicles

Gross testicular heterogeneity on ultrasound has been associated with testis loss following testicular torsion in children. We aimed to quantify the extent of temporal heterogeneity associated with testis loss in testicular torsion cases using a noninvasive technique to determine a HI (heterogeneity index) on ultrasound images. We retrospectively studied the records of patients who presented with acute scrotal pain to the Pediatric Emergency Department over a 6-year period. Ultrasound images of the affected testis and the unaffected contralateral testis were examined using a proprietary program to determine the extent of heterogeneity of each image. The difference between the HI of the torsed testis and that of the contralateral normal testis was termed ΔHI. Receiver operating characteristics curve analysis was performed to determine the ΔHI threshold for nonviability. Among 529 patients who presented with acute scrotal pain 147 had testicular torsion based on surgical findings. Of these 147 patients 110 (74.8%) were found to have a viable testis while 37 (25.2%) had a nonviable testis. Using the ΔHI cutoff of 0.394 or greater for nonviability, sensitivity and specificity were 100% and 94.5%, respectively. Positive and negative predictive values were 86% and 100%, respectively. Our results demonstrate that a quantifiable temporal gradation of heterogeneity exists and the heterogeneity index can be used as an objective parameter to determine the viability of a torsed testicle. By developing the technology to measure the heterogeneity index in real time, we could potentially identify which patients with testicular torsion have a nonviable testicle and, thus, would not require immediate surgical exploration.

Correction of Tibial Torsion in Children With Cerebral Palsy by Isolated Distal Tibia Rotation Osteotomy: A Short-term, In Vivo Anatomic Study.

Excessive internal or external tibial torsion is frequently present in children with cerebral palsy. Several surgical techniques have been described to correct excessive tibial torsion, including isolated distal tibial rotation osteotomy (TRO). The anatomic changes surrounding this technique are poorly understood. The goal of the study was to examine the anatomic relationship between the tibia and fibula following isolated distal TRO in children with cerebral palsy. Twenty patients with 29 limbs were prospectively entered for study. CT scans of the proximal and distal tibiofibular (TF) articulations were obtained preoperatively, at 6 weeks, and 1 year postoperatively. Measurements of tibia and fibula torsion were performed at each interval. Qualitative assessments of proximal and distal TF joint congruency were also performed. The subjects with internal tibia torsion (ITT, 19 limbs) showed significant torsional changes for the tibia between preoperative, postoperative, and 1 year time points (mean torsion 13.21, 31.05, 34.84 degrees, respectively). Measurement of fibular torsion in the ITT treatment group also showed significant differences between time points (mean -36.77, -26.77, -18.54 degrees, respectively). Proximal and distal TF joints remained congruent at all time points in the study.Subjects with external tibia torsion (ETT, 10 limbs) showed significant differences between preoperative and postoperative tibial torsion, but not between postoperative and 1 year (mean torsion 54, 19.3, 23.3 degrees, respectively). Measurement of fibular torsion in the ETT treatment group did not change significantly between preoperative and postoperative, but did change significantly between postoperative and 1 year (mean torsion -9.8,-16.9, -30.7 degrees, respectively). Nine of 10 proximal TF joints were found to be subluxated at 6 weeks postoperatively. At 1 year, all 9 of these joints had reduced. Correction of ITT by isolated distal tibial external rotation osteotomy resulted in acute external fibular torsion. The fibular torsion alignment remodeled over time to accommodate the corrected tibial torsional alignment and reduce the strain associated with the plastic deformity of the fibula. Correction of ETT by isolated distal internal TRO resulted in acute subluxation of the proximal TF articulation in almost all cases. Subsequent torsional remodeling of the fibula resulted in correction of the TF subluxation in all cases. Acute correction of TT by isolated distal TRO occurs by distinct mechanisms, based upon the direction of rotational correction. Level II-Diagnostic.

Case report-ovarian torsion in a child: a painful twist in the tale

Ovarian torsion in children is a rare cause of acute abdominal pain and is a true surgical emergency. The clinical presentation closely resembles other pathologies such as urinary tract infections, gastroenteritis and more common surgical emergencies such as appendicitis. We present a case of previously healthy 6 year old female child who presented with abdominal pain, intermittent fever and vomiting. Ultrasonography of the abdomen and pelvis revealed features suggestive of ovarian torsion for which Subacute Laparoscopic Oophorectomy was performed. The authors would like to sensitize readers to the possibility of ovarian torsion in the paediatric populace and reiterate that timely diagnosis and management can prevent catastrophic sequelae.

Adnexal torsion in children: The role of family practice physicians and paediatricians

Abstract Objectives Ovarian torsion (OT) is uncommon and is initially presented to paediatricians and family medicine physicians. The aim of this study is to assess the presentation, reasons for delayed diagnoses, outcomes, and recommended modalities for the early diagnosis of OT. Methods A retrospective study was carried out in children ≤18 years old from January 2004 to December 2013. The data gathered from medical records included age, presenting symptoms, prior treatment for the same symptoms, delays in presentations, past medical history, clinical findings, diagnostic tests performed, diagnoses and treatments. Results Although the data of 15 patients were collected, only 11 medical records of patients with adnexal torsion were available for complete review. The average age of the participants in this study was 9.9 ± 3.5 years. All patients complained of abdominal pain; whereas 8 (72.7%) patients presented with vomiting. The average duration of symptoms was 39.7 ± 66 h. Each discipline of general practitioners and paediatricians attended four (36.3%) children. The average delay of presentation to the hospital was 52 ± 68.78 h, and the average delay in diagnosis and final surgery after admission to the hospital was 9.1 ± 2.7 h. Ultrasound and Doppler imaging were the only diagnostic tools used for pre-operative diagnoses. Conclusions We believe that paediatricians and general practitioners are the first line of physicians to initially assess patients with OT, and they should have a high index of suspicion while managing patients with OT. They should perform early ultrasound and Doppler and refer patients to tertiary care centres where early intervention could save the patients' ovaries and future fertility.

National Trends in the Surgical Treatment of Ovarian Torsion in Children: An Analysis of 2041 Pediatric Patients Utilizing the Nationwide Inpatient Sample

The aim of this study was to evaluate the national trends in surgical management of ovarian torsion (OT) in children. The Nationwide Inpatient Sample was queried from 1998 to 2011 for females less than 18 years of age with OT. Patients were stratified into three treatment groups: oophorectomy (OO), oophoropexy, or release of torsion (RT) alone. There were 2041 patients with OT, of which 1598 (78%) underwent OO, 126 (6%) oophoropexy, and 317 (15%) RT. RT significantly increased from 1998 to 2011 (9% vs 25%; P < 0.05). At nonteaching hospitals, there were higher rates of OO (89.3% vs 79.5%; P < 0.05) and lower rates of RT (10.7% vs 20.5%; P < 0.05) compared with teaching hospitals. RT was performed at a higher rate in Northeast United States compared with the South (22.7% vs 14.2%; P < 0.05). Girls presenting at nonteaching hospitals and the South had increased odds of undergoing OO compared with those presenting at teaching hospitals and the Northeast (P < 0.05). Although ovarian conservation for OT in children is more often performed in the Northeast United States and at teaching hospitals, this large population-based study demonstrates OO remains the most common surgical management for OT in the United States.

Update on the management of ovarian torsion in children and adolescents.

Ovarian torsion is commonly seen in young girls. Unfortunately it is often misdiagnosed because of its non-specific symptoms and lack of diagnostic modalities. This article focuses on the diagnostic challenge and also the changes in the management of ovarian torsion. We reviewed original reports on the management of ovarian torsion in young girls published from 1984 till 2014. A literature search was conducted by electronic scanning of five electronic database: MEDLINE, EMBASE, SCI, SSCI and CINAHL. In addition, relevant papers and review articles were hand-searched. The search was limited to English language and human studies. The search was conducted by combining the textwords "ovarian torsion", "adnexal torsion", "adolescents" and "oophoropexy". There are no specific symptoms that can be identified as a pathognomonic feature of ovarian torsion. Ultrasound is a useful diagnostic tool, but it is not always reliable in absence of an enlarged ovary. Laparoscopic detorsion is recognized as the mainstay of treatment regardless the condition of the ovaries. Reports have shown favorable ovarian function after detorsion. The role of oopheropexy remains controversial. Clinicians should be aware of ovarian torsion in girls presenting with abdominal pain. A timely management in this young population can help preserve their ovaries and fertility.

Surgical Approach to Ovarian Torsion in Children

Study ObjectiveOvarian torsion in children is a relatively rare cause of acute abdominal pain. This study evaluates the diagnosis and treatment of ovarian torsion with an emphasis on conservative treatment approaches including the long-term follow-up results. Design and ParticipantsPatients with surgically treated ovarian torsions between December 2006 and February 2014 were included in this retrospective study. The patient population consisted of 41 patients with 42 ovaries involved. The mean age was 11 ± 3.9 (range, 1-17) years. The most common presenting symptom was abdominal pain. InterventionAll patients underwent preoperative pelvic color Doppler ultrasonography that identified torsion in 34 (81%) ovaries. ResultsDuring surgery, a right-sided torsion was detected in 25 (59.5%), and a left-sided one was detected in 17 (40.5%) ovaries. An excisional surgery was used for 16 (38%) ovaries, and detorsion with conservation of the ovary was used for 26 (62%). A trend toward conservative management was seen over the years. Regular follow-up for those patients who underwent conservative surgery was done in 22 patients for a mean of 25 months (range, 1.5-83 months). Control color Doppler ultrasonographic results were within normal limits in terms of ovarian size and blood supply in 17 (77%) patients. Despite normal parenchymal echogenicity, an involved ovary was smaller in size compared to the other ovary in five patients. Ovarian follicles were present in three of them. ConclusionThe ovary-sparing, conservative surgery is found to be highly successful in the presented series. Although malignancies are rarely encountered in torsed ovaries with associated masses, biopsy samples should be obtained in suspicious cases.

Surgical Management of Persistent Intoeing Gait Due to Increased Internal Tibial Torsion in Children

Intoeing gait is frequently seen in developing children, and in most cases it resolves with growth. However, persistent, extreme intoeing gait, due to increased internal tibial torsion, may disrupt gait function. At our institution, children with symptomatic intoeing gait are evaluated per a standardized protocol, which includes quantitative gait analysis. When the primary cause is increased internal tibial torsion, surgical correction by supramalleolar tibial rotational osteotomy is recommended. The study design was a retrospective case series, with normative controls (31 children), of typically developing children with symptomatic intoeing gait who were treated by isolated supramalleolar tibial rotation osteotomy (28 children, with 45 treated extremities). Preoperative and 1-year postoperative physical examination, kinematic, kinetic, and pedobarographic data were compared. Patient-reported and parent-reported outcomes in functional and satisfaction domains were assessed by items on a 7-point questionnaire. Internal tibial torsion, foot progression angle, and knee rotation were normalized following tibial rotation osteotomy. Compensatory external hip rotation and external knee progression angle were significantly improved but not normalized following tibial rotation osteotomy. An increased coronal plane knee varus moment was significantly decreased following surgery. Increased sagittal and transverse plane knee moments were significantly decreased but not normalized following surgery. Significant improvements were observed with respect to tripping, falling, foot/ankle pain, and knee pain following surgery. Children with symptomatic intoeing gait because of increased internal tibial torsion have characteristic primary and compensatory kinematic gait deviations that result in increased loading about the knee during the stance phase of gait. Correction of the internal tibial torsion by rotation osteotomy improves, but does not normalize, all the kinematic and kinetic gait deviations associated with intoeing gait. The association between increased internal tibial torsion and degenerative arthritis of the knee in adults may be a consequence of longstanding increased loading of the knee joint due to the kinematic gait deviations seen with intoeing gait. Therapeutic intervention, level III.

EOS analysis of lower extremity segmental torsion in children and young adults

IntroductionLower limb torsion varies substantially among healthy children during growth. Values reported in the literature to date have been obtained using semi-quantitative clinical or 2D measurement methods. Quantitative 3D measurement would help determine the physiological range of lower limb torsion. Low-dose stereoradiography with 3D reconstruction provides a good alternative. Its use increases in pediatrics because of radiation minimization. Previous studies have shown accurate and reproducible results of lower limbs reconstruction in adults and children but the torsional parameters haven’t been measured yet. The present study reports the values of lower limb segmental torsion and its course during growth in a cohort of healthy children and young adults using the EOS low-dose biplanar X-ray. HypothesisEOS 3D reconstruction is an accurate and reproducible method to measure the torsional parameters in children. Materials and methodsFemoral torsion (FT) and tibial torsion (TT) were studied on 114 volunteers (228 lower limbs) from 6 to 30 years of age divided by age into 5 groups. The EOS™ acquisitions were obtained in subjects standing with their feet offset. ResultsMean FT decreased during growth, passing from 21.6° to 18°, whereas mean TT increased from 26.8° to 34.7°. There was a statistically significant difference between the 2 extreme age groups, but no difference was found between any other age groups. The ICC for intra-observer reproducibility was 0.96 and 0.95 for FT and TT for the first operator, and 0.79 and 0.83 for the second operator respectively. The ICC for inter-observer reproducibility was 0.84 and 0.82 respectively. DiscussionThe course of lower limb segmental torsion observed was consistent with literature reports based upon clinical and 2D measurements. 3D reconstruction of EOS low-dose biplanar imaging appears to be a safe and reliable tool for lower limbs measurements, especially for investigating lower limb segmental torsion in children and adults.

The therapeutic effect of tibia counter rotator with toe-out gait plate in the treatment of tibial internal torsion in children.

ObjectiveTo evaluate the therapeutic effect of a Tibia Counter Rotator (TCR) with toe-out gait plate (GP) upon tibial internal torsion by a comparative analysis of transmalleolar angle (TMA) and gait analysis with GP alone.MethodsTwenty participants with tibial internal torsion were recruited for this study. Each 10 participants were included in group A with TCR and GP application and in group B with GP application only. The TMA and the kinematic results were used for the evaluation of the therapeutic effects of orthoses.ResultsWithin each group, TMA showed a significant increase after treatment. Group A showed a continuous improvement up to six months, however, group B showed an improvement up to five months only. Group A showed a significantly higher correction effect than group B after treatment. Regarding kinematic data, both groups showed a significantly decreased mean ankle adduction angle after treatment. However, group A showed a significantly lower mean ankle adduction angle than group B after six months.ConclusionThe group with TCR and GP showed a significantly better outcome and continued correction force compared to the group with GP only. Our results suggest that TCR with GP may be useful therapeutic orthoses for children with tibial internal torsion.

Isolated salpingeal torsion in children: a case series and review of the literature

This study was carried out to evaluate and determine the history, clinical presentation, and physical examination and laboratory findings in a pediatric (n=1) and adolescent (n=2) population with isolated tubal torsion (ITT) and to examine its surgical management. A retrospective review of all the cases of ITT treated in our hospital between January 2000 and December 2012 was performed. The diagnosis of ITT was performed by physical examination and radiological studies including ultrasonography (US), color Doppler US, and computed tomography (CT) and confirmed by surgical intervention. There were 3 children with ITT in the study period. Two of the patients were adolescents and one was diagnosed in the neonatal period. Two patients had left-sided ITT. The neonatal patient was diagnosed with abdominopelvic mass antenatally. ITT in the other two children occurred three days after the onset of symptoms. All the patients in this study were treated with salpingectomy. ITT is rarely diagnosed preoperatively, and is treated mostly by salpingectomy. A better recognition of this entity may help to improve the treatment of this rare condition. As advocated for ovarian salvage in adnexal torsions, earlier diagnosis and preservation of the tube, if possible, with prompt surgical intervention may increase the future reproductive potential of these patients.

Successful laparoscopic surgery for 14-month-old infant with ovarian torsion

The prevalence of ovarian torsion is 4.9 among 100,000 females between ages 1 to 20 years. The diagnosis of ovarian torsion in children, especially in infants, is very difficult. Since they cannot explain related symptoms accurately, and reproductive organs lie high in the abdomen, physical examination shows unclear findings. For these reasons, we use imaging studies, such as ultrasonography and magnetic resonance imaging, to diagnose ovarian torsion. However, it is of limited value to diagnose by using these modalities alone. Therefore, clinical suspicion is important for diagnosis. Though pediatric laparoscopic surgery was introduced 20 years ago, it has been widely performed since the mid 1990s with the development of 3-mm instruments. In addition, usually the pediatric operation is done in the pediatric surgery office, even though it is a gynecologic procedure. In addition, laparotomy is still more frequently conducted in current clinical practice, although the frequency of laparoscopic surgery has increased. However, it is thought that expert gynecologic surgeons can perform pediatric laparoscopic operations if they pay attention to some precautions. We report herein the case of a 14-month-old infant who underwent emergency laparoscopic untwisting of ovarian torsion successfully without complications by a gynecologic surgeon, with a brief review of the literature.

Paraovarian cyst torsion in children: Report of two cases

Paraovarian cysts are assumed to be rare in childhood. This assumption is due to the fact that most patients with paraovarian cyst are asymptomatic unless complicated. Owing to the wide range of pathologies in differential diagnosis, preoperative diagnosis of paraovarian cyst presents a challenge. Herein is reported two cases of complicated paraovarian cyst in children.

Should the ovary always be conserved in torsion? A tertiary care institute experience

AimThe aim of this study was to analyze our experience in conserving ovarian tissue in cases of ovarian torsion, irrespective of grade of necrosis at exploration. Materials and methodsAll children with a diagnosis of ovarian torsion admitted to our hospital from January 2009 to January 2013 were included. Patients with underlying ovarian pathology were excluded. ResultsThere were 13 torsions in 12 children (one bilateral). All underwent detorsion with or without evacuation of hematoma. Follow-up ultrasonography (USG) with color Doppler was done for all 13 ovaries, which showed an ovary with good vascularity and follicular development in 12 ovaries (92%). In 76% (10 of 13) of cases, intraoperatively, the ovary was judged to be moderately to severely ischemic/necrotic. Yet, follow-up sonograms showed the ovary with follicular development in all cases except one (7%). There were no major complications in our series. ConclusionSimple detorsion, instead of traditionally advocated oophorectomy, was not accompanied by an increase in morbidity. On follow-up, almost all patients studied had functioning ovarian tissue despite the grave ischemia observed intraoperatively. Detorsion should be the procedure of choice for all cases of simple ovarian torsion in children.

Ovarian torsion in children: Management and outcomes

BackgroundThe purpose of this study is to evaluate the clinical symptoms, diagnosis, management, and outcomes in children with ovarian torsion. MethodsThe charts of 50 patients with 53 cases of ovarian torsion treated between January 1989 and March 2012 were reviewed retrospectively. Long term follow up was available for 20 girls who had their ovaries left in the abdominal cavity after detorsion. ResultsIn 22 cases ovaries were removed, and in 31 cases the torsion was relieved and the ovaries left in the abdominal cavity. Twenty-five of the salvaged ovaries were black-bluish and 10 bluish in color. Since 2005, after a change in preferred treatment, all ovaries treated by detorsion were left in the abdominal cavity. The long term results were observed clinically and by ultrasound in 20 girls. Multifollicular ovaries were found in 17 girls. One girl had a normal size paucifollicular ovary, a one-year-old girl had a normal size ovary with microfollicles, and one girl had no ovarian material detectable by ultrasound. ConclusionsLong term analysis of the treatment of ovarian torsion revealed that ovaries treated by detorsion and left in the abdominal cavity preserved their normal anatomy and function. Conservative surgical treatment proved to be safe. None of the girls had thromboembolism or peritonitis, and no malignant tumors were found in the operated ovaries.
