Postoperative bladder and rectal function in children with sacrococcygeal teratoma

Management strategy and outcomes of sacrococcygeal teratoma - an Egyptian multicenter experience

OBJECTIVES

Nationwide criteria regarding patients with sacrococcygeal teratoma (SCT) are still lacking in Egypt. We aimed to present a multicenter study regarding the management and outcomes of this tumor to evaluate our national treatment strategy.

METHODS

A retrospective analysis including all patients with SCT who were managed at four major Egyptian centers between 2013 and 2023. Clinical data, surgical approaches, and short- and long-term outcomes were discussed.

RESULTS

The study included 95 patients (74 were females). Antenatal diagnosis was reported in 25% of patients. Seventy-one patients (74.7%) were classified as Altman type I/II. Surgery was performed via a perineal approach in 75 patients, whereas the remaining 20 underwent a combined abdominoperineal approach. Vertical elliptical incision with midline closure was conducted in 51.5% of patients, followed by classic or modified chevron incisions. Benign mature teratoma was detected in 82% of patients. At a median follow-up of 57 months, eight patients (8.5%) had relapsed. The 5-year overall survival (OS) and event-free survival (EFS) of all patients were 94% and 91%, respectively. In the after-care monitoring, 19 patients (20%) had urinary or bowel dysfunctions. Nine of them were managed using medications. Clean intermittent catheterization was practiced in another five patients. The remaining five underwent further surgical interventions.

CONCLUSION

Favorable outcomes were achieved in our country during the last decade. Diverse perineal incisions were performed for resection, and vertical elliptical with midline closure was the commonest. During follow-up, 20% of patients developed urological or bowel dysfunctions that required medical and surgical treatment modalities to improve their quality of life.

Sacrococcygeal teratoma: Long-term outcomes. A UK CCLG Surgeons Group Nationwide Study

AIM

Sacrococcygeal teratoma (SCT) is a rare paediatric germ cell tumour (1:40,000). Long-term data regarding urinary tract and bowel function after SCT resection is limited to few studies. A UK Children's Cancer and Leukaemia Group (CCLG) Surgeons multicentre study aimed to critically analyse long-term functional outcomes in patients following resection of SCT.

METHODS

Nationwide study of UK paediatric surgical oncology centres using a standardised data collection form. All index cases of newborn infants and children <16 years with SCT diagnosis during 2005-2015 were included.

RESULTS

165 SCT patients treated at 14 UK paediatric surgical oncology centres were included. Median age at presentation was 1 day [interquartile range, IQR: 0-25]; median age at surgery was 10 days [IQR: 4-150]. One hundred seventeen (70%) were female and 48 (30%) male. Antenatal diagnosis was made in 44% index cases. Total 59% of patients were Altman Stage I or II lesions. Follow-up data were available in 83% cases. Tumour recurrence occurred in 13 (7%) patients at median age 13 months [IQR: 8.75-30 months]. Fifty-nine (36%) of 165 patients had documented adverse bladder or bowel dysfunction. Twenty-two (37%) cases required urinary clean intermittent catheterisation (CIC) urology health care, with eight patients (14%) needing operative intervention to control management of bowel dysfunction.

CONCLUSION

This UK CCLG study showed 36% of SCT patients develop bladder or bowel dysfunction after primary tumour resection. Functional assessment of bladder and bowel function is mandatory during after-care follow-up of all SCT patients. A multidisciplinary care pathway, with surgeon speciality groups including surgical oncology, paediatric urology and paediatric colorectal specialists, is strongly advised to facilitate 'best practice' monitoring of long-term health and improve patient quality of life (QoL) into adulthood.

Long-term functional outcomes of sacrococcygeal teratoma - A systematic review of published studies exploring 'real world' outcomes

Sacrococcygeal teratoma (SCT) is a rare neoplasm affecting 1:35,000 newborns. Long-term follow-up from small observational studies report impaired bladder/bowel function. This current study comprehensively analyses all published studies to better define true long-term functional sequelae. Medline/Embase databases were searched with PRISMA guidelines. Final analysis yielded 37 studies involving 1116 patients (854 female; 77%). Individual datasets were available in 14 studies (222 patients). According to Altman classification - 298/845 (35%) were Type I, 252/845 (30%) Type II, 133/845 (16%) Type III, and 128/845 (15%) Type IV tumours. Most neoplasms were benign (640/858; 75%), 77/858 (9%) immature and 141/858 (16%) malignant. Abnormal bladder function was reported in 7/39 (18%) Altman Type I, 23/61 (37.7%) Type II, 11/34 (32.4%) Type III, and 15/25 (60%) Type IV cases (p = 0.007). Adverse urological outcomes were notably common in immature/malignant neoplasms vs benign tumours and in patients requiring reoperation(s); p = 0.002 and p = 0.01. Bowel dysfunction was evident in 19% index cases and constipation in 26% with no significant association(s) with tumour characteristics. Higher Altman stage, unfavourable tumour biology and reoperation are associated with poor functional outcome(s). Multidisciplinary management from primary diagnosis of SCT is crucially important for all patients to best optimise functional outcomes across surgical specialities.

Functional fecal and urinary outcomes after sacrococcygeal mass resection in pediatric patients

BACKGROUND

Sacrococcygeal masses (SCM) are uncommon in children. The purpose of this study is to review the functional fecal and urinary outcomes following resection of SCM and to determine the impact of a multidisciplinary clinic (MDC) on these outcomes.

METHODS

A retrospective review was performed of patients who underwent SCM resection between 1979 and 2019. Baylor Social Continence Scale (BCS), Vancouver Symptom Score (VSS) and Cleveland constipation score (CSS) surveys were used to assess fecal and urinary continence at time of most recent follow up. Age, tumor characteristics, histopathology, and type of anorectal malformations (ARM), if present, were also recorded.

RESULTS

75 patients were included. 51 (69%) patients were females and 23 (31%) had an associated ARM. The median age at resection was 8.5 months (IQR 0-26.8). 41 (56%) patients were followed in the MDC. 27 (82%) of patients seen in the MDC were clean for stool and 26 (87%) were dry for urine, while only 17 (59%) of patients not seen in the MDC were clean for stool and dry for urine (p<0.05). There was improvement in Baylor, Vancouver and Cleveland scores.

CONCLUSIONS

A multidisciplinary approach to the care of patients following SCM resection may improve bowel and bladder outcomes.

Neurogenic Bowel Dysfunction in Children and Adolescents

Neurogenic/neuropathic bowel dysfunction (NBD) is common in children who are affected by congenital and acquired neurological disease, and negatively impacts quality of life. In the past, NBD received less attention than neurogenic bladder, generally being considered only in spina bifida (the most common cause of pediatric NBD). Many methods of conservative and medical management of NBD are reported, including relatively recently Transanal Irrigation (TAI). Based on the literature and personal experience, an expert group (pediatric urologists/surgeons/gastroenterologists with specific experience in NBD) focused on NBD in children and adolescents. A statement document was created using a modified Delphi method. The range of causes of pediatric NBD are discussed in this paper. The various therapeutic approaches are presented to improve clinical management. The population of children and adolescents with NBD is increasing, due both to the higher survival rate and better diagnosis. While NBD is relatively predictable in producing either constipation or fecal incontinence, or both, its various effects on each patient will depend on a wide range of underlying causes and accompanying comorbidities. For this reason, management of NBD should be tailored individually with a combined multidisciplinary therapy appropriate for the status of the affected child and caregivers.

Significant rate of lower urinary tract dysfunction in patients with sacrococcygeal teratomas

BACKGROUND

Sacrococcygeal teratoma (SCT) is the most commonly occurring presacral tumor and can affect the lower urinary tract by direct mass effect, or as a sequela from surgical resection. Despite the potential impact on urologic function, there is no current standard for urological involvement or follow-up for these patients. The purpose of this study was to evaluate the need for urologic involvement for lower urinary tract dysfunction (LUTD) in patients with SCTs at our institution.

METHODS

We performed a retrospective chart review of patients diagnosed with SCT and managed at our institution between 1990 and 2019. Data collected included: patient demographics, surgical and pathology reports, presence of tethered cord or anorectal malformation, and need for urologic involvement for LUTD. LUTD included acute urinary retention, need for chronic intermittent catheterization, and/or urinary incontinence. Acute urinary retention was defined as requiring catheterization to empty the bladder for a limited time (outside the standard post-operative indwelling catheter time period) and the eventual return to spontaneous voiding. Chronic intermittent catheterization was defined as those with urinary retention that has persisted and required continued catheterization at the time of chart review. Urinary incontinence was defined as urine leakage in children older than 3 years of age. Patients with unavailable records were excluded. Comparison between groups was performed with Mann Whitney and chi-squared tests.

RESULTS

Forty-five patients with SCTs were identified. LUTD was identified in 23 patients (51%). The most common reason for LUTD was urinary retention (n = 16, 70%): 9 patients had acute retention and 7 had chronic retention (Fig. 1). Nine patients (39%) had urinary incontinence: 2 of these patients (4% of all SCT patients) had urinary fistulas (vesicovaginal (n = 1) and urethrovaginal (n = 1)). Only 5 patients (22%) had LUTD recognized preoperatively. Nine patients had concomitant tethered cord, and 7 of these (78%) had LUTD. Of patients with LUTD, Altman type IV was the most common location (n = 10, 43%). There was no significant difference in tumor type between those with and without LUTD. Patients without LUTD had significantly shorter follow-up.

CONCLUSIONS

Greater than 50% of patients with SCTs have known LUTD. Two of these patients were found to have urinary fistulas requiring urinary diversion. A multidisciplinary team including urology should be involved upfront in the management of patients with SCTs, and LUTD should be routinely assessed at follow-up visits. Evaluation for a urinary fistula should occur in the presence of urinary incontinence.

Need for urodynamic evaluation as a regular follow-up tool in assessment of long-term urological outcomes in patients with sacrococcygeal teratoma

AIM

To assess the long-term urologic outcomes in follow-up of patients of sacrococcygeal teratoma (SCT) using urodynamic study (UDS) in addition to clinical and radiologic evaluation.

METHODS

A prospective study of clinical, radiological and urodynamic evaluation in patients with SCT who underwent resection between January 2002-June 2015 and were followed up till January 2016 was conducted.

RESULTS

Total 57 patients, 42 (73.7%) females and 15 (26.3%) males with 35 (62.4%) following treatment for benign and 22 (38.5%) for malignant disease were included. Twenty-eight of 57 (49.12%) had urological problems. Clinical complaints in 21 (36.8%) patients included stress urinary incontinence-14 (66.7%), enuresis-9 (42.9%), and poor stream or dribbling of urine-6 (28.6%). Eight of 51 patients (15.7%) had abnormal ultrasound findings, which included contracted, trabeculated thick walled bladder (3), bilateral hydronephrosis (3) and significant post void residue (PVR) (6). Seven of 57 underwent micturating cystourethrogram (MCU), 5 had an abnormal report[significant PVR (4), small trabeculated bladder (3), reflux (2) and large capacity bladder (1)]. Urodynamic study was done in 27 patients, 18/27 (66.7%) had abnormalities. Six patients without any clinical or ultrasonographic abnormalities had abnormal UDS. Total 28 (49.12%) had urological comorbidities. Three patients had overactive bladder, five dysfunctional voiding, one underactive bladder and one had giggle incontinence. Children were managed by behaviour therapy and pharmacotherapy.

CONCLUSION

Urodynamic evaluation could detect abnormalities in patients who had no urinary complaints or abnormality on ultrasound. The abnormalities have a potential for progressive upper tract damage. Urodynamics should be an integral part of urological surveillance in patients operated for SCT.

Functional outcome and health-related quality of life in patients with sacrococcygeal teratoma - a Swedish multicenter study

BACKGROUND/PURPOSE

The aims of this study were to evaluate bowel and urinary tract function, to identify predictors for dysfunctional outcome and to evaluate health-related quality-of life (QoL) in patients treated for sacrococcygeal teratomas (SCT).

METHODS

Medical records of patients with SCT born between 1985 and 2015 treated at three Swedish pediatric surgical centers were reviewed. Questionnaires regarding urinary tract function, bowel function and QoL were sent to patients and parents. Different QoL instruments were used for the different age groups.

RESULTS

Totally 85 patients were identified. Four patients died in the neonatal period. Forty-nine patients answered the questionnaires (60%). Median age at follow-up was 8.9 years (range 3.6-28.8). Bowel dysfunction was reported by 36% and urinary tract dysfunction by 46% of the patients. Univariate analysis revealed that urinary tract dysfunction correlated with gestational age (p = 0.018) and immature histology (p = 0.008), and bowel dysfunction correlated with gestational age (p = 0.016) and tumor size (p = 0.042). Low gestational age was an independent predictor for both urinary tract and bowel dysfunction. Good or very good QoL was reported by 56% of children aged 4-7 years, 90% of children aged 8-17 years and 67% of the adults.

CONCLUSION

Although a considerable proportion of bowel and urinary tract dysfunction was found, the reported QoL was good in a majority of the patients with SCT. Low gestational age was found to be a predictor for bowel- and urinary tract dysfunction.

Unresectable recurrence malignant sacrococcygeal teratoma in children treated with chemoradiotherapy: Case report and literature review

Sacrococcygeal teratoma is the most common germ cell neoplasia that consists of tissues derived from primitive germ layers. Approximately 10-20% of patients are malignant. Because of the high rate of recurrence, treatment strategies for malignant sacrococcygeal teratomas are limited. Hence, we report a case of malignant sacrococcygeal teratoma treated with concurrent chemoradiotherapy plus adjuvant chemotherapy and review the literature. This case report indicates that chemoradiation plus adjuvant chemotherapy may be a treatment option for malignant SCT which is not technically resectable or with residual lesion after surgery.

Acquired Urethrovaginal Fistula and Urethral Atresia in a Patient with a Sacrococcygeal Teratoma

Acquired urethrovaginal fistulae and urethral atresia are rare findings in pediatric patients, but have been described in adult patients related to trauma or iatrogenic injury. Little exists in the published literature to guide management of such conditions in children, but lessons learned from congenital causes can help. Herein we discuss the preoperative evaluation and management of a child with an acquired urethrovaginal fistula and urethral atresia likely related to in utero compression from an intrapelvic sacrococcygeal teratoma and provide several images detailing the complex anatomy.

Late effects in patients with sacrococcygeal teratoma: A single center series

INTRODUCTION

The aim of this study is to evaluate late side effects that affect quality of life in children with sacrococcygeal teratoma (SCT).

PATIENTS AND METHODS

The patients with SCT were evaluated retrospectively. The data were expressed by percentage and the subgroups were compared statistically.

RESULTS

A total of 40 children with SCT were identified with median age 12 days (range: 1 day-14.6 years), 27 of whom were analyzed in this study with urodynamic data available for 24 and anal manometric evaluations for 20. Chronic constipation with need for laxative was reported in (7/27) 25.9%, fecal incontinence was present in (1/27) 3.7%, and urodynamic abnormalities were reported in (16/24) 66%. Among those with urodynamic abnormalities, low bladder capacity, dyssyergia and neurogenic bladder were observed in (21/24) 87.5% and anticholinergic treatment was applied. Urinary incontinence was present in (2/27) 7%, with clean intermittent catheterization utilized in (7/27) 25.9%. While defecation was observed more in the patients with Altman types II, III, and IV, micturation problems were observed more in the patients with Altman types II and IV. It was found that urodynamic dysfunctions were more frequent in the patients with increased number of operations.

DISCUSSION

Although the rate of symptomatic patients was low, abnormalities determined by radiological and urodynamic evaluations were high.

[Functional and aesthetic evaluation of sacrococcygeal teratomas. Not everything ends with surgery]

INTRODUCTION

Sacrococcygeal teratoma is the most common solid neonatal tumour. The improvement in survival has meant that postoperative sequelae can be diagnosed and treated. The aim of this article is to evaluate the long-term outcomes of patients treated in our centre.

MATERIAL AND METHODS

Records of patients treated for a sacrococcygeal teratoma in our hospital from 1977 to 2014 were retrospectively reviewed. Personal data was collected and a telephone questionnaire was used to assess long-term bowel and urinary habits, as well as an aesthetic and functional self-assessment.

RESULTS

A total of 14 patients were treated during the study period, of whom 11 were females and 3 males, with a mean age at the time of the survey of 17 years (8 months-37 years). Eight patients completed the questionnaire (57.1%). The mean age of the 8 patients was 23 years (4-37 years), of whom 37.5% were operated on due to a sacrococcygeal teratoma type i, 25% type ii, 25% type iii, and 12.5% type iv. Two of them (25%) had constipation, and one (12.5%) had faecal incontinence. Two (25%) patients suffered from recurrent urinary tract infections, and 3 (37.5%) patients had urinary incontinence. Five patients (62.5%) had a perception of being physically impaired, with limitation of their social life.

CONCLUSIONS

The incidence of constipation does not differ from that found in the literature. Faecal incontinence is slightly improved compared to what has been published. However, urinary tract infections and incontinence are more prevalent in our series. Five patients out of the eight that responded suffered from psychosocial problems, according to DAS-59 questionnaire. Patients with SCT require urological, bowel, and psychological counselling, until they have a complete functional and emotional development.

Sexual function after treatment for sacrococcygeal teratoma during childhood

BACKGROUND

Children treated for sacrococcygeal teratoma (SCT) may suffer from sexual dysfunction later in life because of the extended pelvic surgery performed, however, structured evaluations have not been performed yet.

METHODS

The Female Sexual Function Index (FSFI), the International Index of Erectile Function (IIEF) and the Body Image Questionnaire (BIQ) were sent to patients (≥18years) treated for SCT in the Dutch pediatric surgical centers after 1970.

RESULTS

Forty-five of 76 patients returned the questionnaires; 28 women (median age 27.3years, range 18.3-41.0) and seven men (median age 22.0years, range 19.1-36.5) were eligible for analysis. The FSFI and IIEF results were compared to healthy controls. Female patients scored significantly lower on the desire (p=0.014), arousal (p=0.013) and lubrication domain (p=0.019). FSFI total-scores of female patients were significantly lower compared to controls [median 30.5 (IQR 28.6-31.4) vs. median 32.4 (IQR 30.6-33.45) p≤0.001] but were above the threshold value for sexual dysfunction. Males reported normal erectile function and penetration ability with normal ejaculation. Females had significant lower BIQ results compared to males; BIQ-cosmesis scores were moderately correlated to the FSFI-desire score (r=-0.37, p=0.028).

CONCLUSION

SCT resection in girls may result in diminished sexual function at adult age with worse self-perceived body image. The possibility of sexual complaints should be integrated in the surveillance strategies for these patients.

Patient-Reported Defecation and Micturition Problems Among Adults Treated for Sacrococcygeal Teratoma During Childhood--The Need for New Surveillance Strategies

BACKGROUND

To evaluate defecation and micturition complaints in adults treated for sacrococcygeal teratoma (SCT) during childhood and to identify risk factors for soiling, urinary incontinence, and constipation beyond childhood.

PROCEDURE

Records of patients aged ≥18 treated for SCT during infancy in the Netherlands were retrospectively reviewed. Frequency and severity of soiling, constipation, and urinary incontinence were evaluated using questionnaires designed in line with the Krickenbeck classification. Problems during childhood were compared to outcomes at adult age in part of the cohort. Associations between patient- and disease-related factors with complaints beyond childhood were analyzed with the chi-square test or Fisher's exact test, when appropriate.

RESULTS

Of 47 included patients (mean age 26.2 years, SD ±6.5), 49% reported at least one defecation or micturition complaint. Urinary incontinence was present in 30% and had a greater negative impact than soiling (24%). Ten patients (21%) reported constipation; five found this severely bothering. Three patients reported social restrictions due to defecation or micturition complaints (6.4%). While sex and tumor histology were not identified as risk factors, a tumor diameter of >10 cm and Altman type I or type II SCT were associated with constipation during adulthood.

CONCLUSIONS

One-third of the patients treated for SCT during childhood reported urinary and defecation problems beyond childhood. In only a minority of cases, these led to social restrictions. A greater tumor diameter was associated with a higher risk of constipation during adulthood. Prolonged surveillance strategies are advised for all patients with SCT.

Urologic co-morbidities associated with sacrococcygeal teratoma and a rational plan for urologic surveillance

BACKGROUND

Sacrococcygeal teratoma (SCT) is one of the most common neonatal and fetal tumors. SCT pelvic mass effect and the need for aggressive surgical resection, create potential for urologic co-morbidity. We reviewed our experience with SCTs and propose a rational plan for urologic surveillance.

METHODS

We retrospectively reviewed all patients with SCT evaluated at our institution from 2004 to 2011. We collected data on the need for reconstructive surgery related to the urologic co-morbidity, the time to detection of urologic co-morbidity, and length of follow-up.

RESULTS

We identified 28 patients evaluated during the study period with a median follow-up of 3.1 year (range 0.14-13.4). The Altman classifications were--type I: 7 (25%), II: 15 (53.6%), and III: 6 (21.4%). Eighteen (64.3%) patients had an associated urologic co-morbidity: 12 (42.9%) patients had hydronephrosis, VUR--10 (35.7%), NGB--13 (46.4%), and 4 (14.3%) developed ≥CKD2. When comparing the patients according to Altman classification, there was a trend towards more urologic co-morbidity in patients with increasing pelvic involvement, P = 0.06. Eleven patients (39.3%) had delayed urologic evaluation and five (17.9%) required reconstructive urologic surgery. In comparing these groups, 4 of 11 (36.4%) undergoing delayed urologic evaluation progressed to reconstruction, as opposed to only one of 17 (5.7%) with urologic evaluation within first year of life (P-value = 0.06).

CONCLUSION

Urologic co-morbidities are common in children with SCT and appear most common in patients with more pelvic tumor involvement (≥Altman II). A risk-adapted approach to urologic surveillance is proposed.
