Objective: This study seeks to describe the pattern of intracranial tumours in Korle Bu Teaching Hospital (KBTH) based on patient demographics, clinical presentation, spatial distribution of tumour and histological findings. Method: The study design is retrospective and descriptive. Data was obtained from the clinical records of patients with intracranial tumours treated in our neurosurgery unit between January 2010 to December 2015, and histology reports obtained from the histopathology unit. Patients with intracranial tumours without definitive histological diagnosis were excluded. Results: Of the 102 histologically diagnosed brain tumours, out of 335 brain tumour cases seen in the period under review, 58 (56.9%) were females and 44 (43.1%) were males (p = 0.031). Gliomas were the commonest intracranial tumours-39(38.2%) followed by Meningiomas 37(36.2%) and Pituitary Adenoma-9(8.8%). Astrocytoma was the commonest type of Glioma comprising 30(77%) of the 39 cases. Meningotheliomatous meningioma was the commonest type of meningioma with 11 (29.7%) of 37 cases. Of the 39 Gliomas 17(43.6%) were males and 22(56.4%) were females, while for the Meningioma 17(46%) were males and 20(54%) were females. The commonest symptom was headache (64%) and the commonest tumour location was supratentorial (77.5%). The crude incidence rate of intracranial tumours in this study was 1.34 per 100,000 populations per year. Conclusion: Gliomas are the commonest intracranial tumours seen in our series. Overall, females were more commonly affected than males in most brain tumours in this series, including both gliomas and meningiomas.
OBJECTIVEComplications in pediatric neurooncology surgery are seldom and inconsistently reported. This study quantifies surgical morbidity after pediatric brain tumor surgery from the last decade in a single center, using existing morbidity and outcome measures.METHODSThe authors identified all pediatric patients undergoing surgery for an intracranial tumor in a single tertiary pediatric neurosurgery center between January 2008 and December 2018. Complications between postoperative days 0 and 30 that had been recorded prospectively were graded using appropriate existing morbidity scales, i.e., the Clavien-Dindo (CD), Landriel, and Drake scales. The result of surgery with respect to the predetermined surgical aim was also recorded.RESULTSThere were 477 cases (364 craniotomies and 113 biopsies) performed on 335 patients (188 males, median age 9 years). The overall 30-day mortality rate was 1.26% (n = 6), and no deaths were a direct result of surgical complication. Morbidity on the CD scale was 0 in 55.14%, 1 in 10.69%, 2 in 18.66%, 3A in 1.47%, 3B in 11.74%, and 4 in 1.05% of cases. Morbidity using the Drake classification was observed in 139 cases (29.14%). Neurological deficit that remained at 30 days was noted in 8.39%; 78% of the returns to the operative theater were for CSF diversion.CONCLUSIONSTo the authors’ knowledge, this is the largest series presenting outcomes and morbidity from pediatric brain tumor surgery. The mortality rate and morbidity on the Drake classification were comparable to those of published series. An improved tool to quantify morbidity from pediatric neurooncology surgery is necessary.
OBJECTIVE
Our objective was to quantify resection outcomes and operative morbidity in paediatric brain tumour surgery using existing scales, assessing their applicability.
METHODS
We investigated morbidity using the Clavien-Dindo (CD) scale and the Drake classification. All paediatric patients receiving a biopsy or craniotomy for an intracranial tumour in a single tertiary paediatric neurosurgery centre between January 2008 and December 2018 were studied. Complications up to day 30 post op were graded.
RESULTS
There were 459 operations: 92 biopsies and 367 craniotomies comprising 166 infratentorial and 292 supratentorial tumours. Median age was 9 years (56% male). The surgical goal was achieved or exceeded in 94% of cases. Thirty-day mortality was 1.31% with all deaths related to disease and none to surgical complications. The overall CD score was 1 in 10.9% of cases, 2 in 18.9%, 3A in 1.7%, 3B in 11.8%, and 4 in 1.1%. There was no operative morbidity in 54% of cases. Using the Drake classification, meningitis was seen in 3.92% of cases, seizures in 3.92%, neurological deficit (that persisted at 30 days) in 8.5%, CSF leak in 5.01%, wound infection in 1.96%, haemorrhage 1.75 %, shunt infection in 1.53%, shunt block in 0.65%, medical complications in 2.4%, and others in 3.05%.
CONCLUSIONS
This is the largest series presenting morbidity from paediatric brain tumour surgery, and the first to validate the CD scale. Our morbidity on the Drake scale was comparable with other series. There is a need to develop improved tools to quantify morbidity in this high-risk specialty.
