Abstract
INTRODUCTION Due to their delicate and deep-seated location, tumors in the pineal region of the brain pose exceptional challenges in neurosurgical management. Highly precise procedures have become crucial to address these complexities, such as the simultaneous performance of biopsy and endoscopic third ventriculostomy (ETV). Our aim was to assess the feasibility, safety, and efficacy of simultaneous biopsy and ETV for treating patients with pineal region tumors. METHODS Medline, Embase, and Web of Science were searched for English studies from January 2000 to February 2024, following Cochrane and PRISMA guidelines. Eligible studies encompassed a minimum of four patients and examined at least one of the following outcomes: good clinical outcomes and the necessity of shunt placement. Single proportion analysis with 95% confidence intervals was conducted under a random-effects model, employing the I2 statistic to assess heterogeneity. Additionally, publication bias was evaluated using the ROBINS-I tool. RESULTS After a meticulous selection process, eighteen studies involving 390 patients were included in the analysis. Overall, good clinical outcomes were observed in 131 out of 147 patients, representing a rate of 92 % (95 % CI: 84 % to 100 %, I2 = 62 %) through random effects analysis. Subgroup analysis showed that children exhibited a notably high rate of good clinical outcomes, reaching 100 % (95 % CI: 96 % to 100 %, I2 = 0 %). Regarding the need for shunt placement, out of the 356 patients assessed, only 39 required shunt placement, yielding a rate of 8 % (95 % CI: 4 % to 12 %, I2 = 63 %). Further sub-analyses indicated shunt requirement rates of 12 % for children and 3 % for adults. Specifically focusing on adults, data from 46 patients who underwent biopsy revealed a success rate of 84 % (95 % CI: 62 % to 100 %, I2 = 81 %). Remarkably, no major complications were reported among adults, resulting in a rate of 0 % (95 % CI: 0 % to 6 %, I2 = 0 %). Additionally, low rates of mortality related to the procedure were observed in adults, with two deaths recorded among the 46 patients analyzed, resulting in a mortality rate of 1 % (95 % CI: 0 % to 7 %, I2 = 0 %). CONCLUSION In conclusion, our study aimed to assess the feasibility, safety, and efficacy of performing simultaneous biopsy and ETV for patients with pineal region tumors. We meticulously examined clinical aspects and patient outcomes, including good clinical outcomes, the requirement for shunt placement after ETV, biopsy success rates, mortality, and complications.

Simultaneous Single-Trajectory Endoscopic Biopsy and Third Ventriculostomy in Pineal Region Tumors: A Systematic Review and Single Arm Meta-Analysis. World Neurosurg 2024; 184:e708-e719. [PMID: 38340795 DOI: 10.1016/j.wneu.2024.02.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2024] [Revised: 02/02/2024] [Accepted: 02/03/2024] [Indexed: 02/12/2024]
Abstract
OBJECTIVE To assess the efficacy and surgical outcomes of the simultaneous single-trajectory endoscopic biopsy and third ventriculostomy (ETV) in pineal region tumors. METHODS A systematic review and meta-analysis adhering to Cochrane Standards and PRISMA framework were conducted. PubMed, Embase, and Web Of Science databases were searched until December 2023. Outcomes included rate of histopathologic diagnosis success, ETV success, complications, required VPS, and mortality. RESULTS Seventeen studies (N = 388) met inclusion criteria. Histopathologic diagnosis success rate was 90% for general population (95% CI: 86%-95%; I2 = 42%) and 94% for pediatric patients (95% CI: 89%-98%; I2 = 19%). ETV Success rate was 93% (95% CI: 88%-97%; I2 = 60%). An estimated risk of postoperative ETV complications was found to be 16% for the general population (95% CI: 5%-28%; I2 = 90%) and 5% for pediatric patients (95% CI: 0%-13%; I2 = 51%). The risk of requiring VPS was estimated as 2% (95% CI: 0%-4%; I2 = 39%) and for the pediatric population it was 7% (95% CI: 0%-16%; I2 = 69%). Mortality risk was found to be 1% (95% CI: 0%-3%; I2 = 0%). CONCLUSIONS Simultaneous endoscopic biopsy and ETV demonstrated high diagnostic and therapeutic success rates. The procedure's safety profile, with low mortality and complications, supports its role in treating hydrocephalus associated to pineal region tumors. Subgroup analyses revealed higher diagnostic success rates and required VPS in the pediatric population, whilst it had lower complication rates.

Abstract
BACKGROUND Pineal region lesions are more common in children than adults; however, therapeutic strategies for pineal region lesions in children are controversial. METHODS A retrospective study involving 54 pediatric with pineal region lesions was conducted. The therapeutic strategies for lesions and hydrocephalus were classified and analyzed. RESULTS Radiotherapy of pineal region lesions was shown to result in better postoperative recovery and fewer complications in the short-term compared with lesion resection. Total resection was related to smaller lesion size, endoscopic procedures, and a better prognosis. Cerebrospinal fluid (CSF) diversion before the resection reduced hydrocephalus recurrences, whereas further lesion resection had a negative short-term influence on CSF diversion. Among the 4 therapeutic strategies to manage hydrocephalus, a third ventriculostomy (ETV) was reasonable and further resection did not have a negative impact on the ETV. The relief of hydrocephalus was also related to better postoperative recovery, a higher total resection rate, fewer complications, and a better prognosis. Logistical regression analysis indicated that lesion size and intracranial complications were predictors of outcome. CONCLUSIONS For lesion treatment, total resection and radiotherapy are essential components in children. Total resection and CSF diversion before resection were beneficial, whereas further lesion resection had a negative impact on CSF diversion. For hydrocephalus treatment, ETV was shown to be the best therapeutic strategy for management of pediatric hydrocephalus. Total resection and better preoperative health status were associated with greater hydrocephalus relief. For the overall prognosis, a lack of hydrocephalus relief was associated with poor outcomes. Lesion size and intracranial complications may be the best predictors of outcome.

Abstract
INTRODUCTION Pineal region tumors (PRTs) are tumors arising from the pineal gland and the paraspinal structures. These tumors are rare and heterogeneous that account for 2.8-10.1% and 0.6-3.2% of tumors in children and in all ages, respectively. Almost all types and subtypes of CNS tumors may be diagnosed in this region. These tumors come from cells of the pineal gland (pinealocytes and neuroglial cells), ectopic primordial germ cells (PGC), and cells from adjacent structures. Hence, PRTs are consisted of pineal parenchyma tumors (PPTs), germ cell tumors (GCTs), neuroepithelial tumors (NETs), other miscellaneous types of tumors, cystic tumors (epidermoid, dermoid), and pineal cyst in addition. The symptoms of PRTs correlate to the increased intracranial cranial pressure due to obstructive hydrocephalus and dorsal midbrain compression. The diagnostic imaging studies are mainly MRI of brain (with and without gadolinium) along with a sagittal view of whole spine. Serum and/or CSF AFP/β-HCG helps to identify GCTs. The treatment of PRTs is consisted of the selection of surgical biopsy/resection, handling of hydrocephalus, neoadjuvant and/or adjuvant therapy according to age, tumor location, histopathological/molecular classification, grading of tumors, staging, and threshold value of markers (for GCTs) in addition. METHODS In this article, we review the following focus points: 1. Background of pineal region tumors. 2. Pineal GCTs and evolution of management. 3. Molecular study for GCTs and pineal parenchymal tumors. 4. Review of surgical approaches to the pineal region. 5. Contribution of endoscopy. 6. Adjuvant therapy (chemotherapy, radiotherapy, and combination). 7. FUTURE DIRECTION RESULTS In all ages, the leading three types of PRTs in western countries were PPTs (22.7-34.8%), GCTs (27.3-34.4%), and NETs (17.2-28%). In children and young adults, the leading PRTs were invariably in the order of GCTs (40-80.5%), PPTs (7.6-21.6%), NETs (2.4-37.5%). Surgical biopsy/resection of PRTs is important for precision diagnosis and therapy. Safe resection with acceptable low mortality and morbidity was achieved after 1970s because of the advancement of surgical approaches, CSF shunt and valve system, microscopic and endoscopic surgery. Following histopathological diagnosis and classification of types and subtypes of PRTs, in PPTs, through molecular profiling, four molecular groups of pineoblastoma (PB) and their oncogenic driver were identified. Hence, molecular stratified precision therapy can be achieved. CONCLUSION Modern endoscopic and microsurgical approaches help to achieve precise histopathological diagnosis and molecular classification of different types and subtypes of pineal region tumors for risk-stratified optimal, effective, and protective therapy. In the future, molecular analysis of biospecimen (CSF and blood) along with AI radiomics on tumor imaging integrating clinical and bioinformation may help for personalized and risk-stratified management of patients with pineal region tumors.

Abstract
Obtaining a prompt diagnosis, avoiding indwelling ventriculoperitoneal shunt, and enhancing the predictive value of pathologic examinations are only some of the advantages conferred by a simultaneous third ventriculostomy and tumor biopsy in patients with pineal region tumors. The objective of this study was to retrospectively search the literature on concomitant, single burr hole endoscopic third ventriculostomy (ETV) and tumor biopsy (TB) for pineal region tumors and to analyze the feasibility, surgical safety, and benefits of these 2 combined procedures. Consequently, a comprehensive, systematic literature search was performed in compliance with the updated PRISMA 2020 guidelines within electronic databases MEDLINE/PubMed, EMBASE, PLOS, and Cochrane Library. Statistical analysis was performed with IBM SPSS 28.0.1.1(14), using Kendall's and Spearman's tests, with a P < 0.05 considered significant. A total of 25 studies were selected and included in this review, for a total of 368 patients (mean age 20.6 years; range 1-86 years; SD 17.5). More than two-thirds of the procedures were operated with a rigid endoscope and 27.6% were performed with either a flexible endoscope, a combination of the 2, or not otherwise specified. Germinoma represented the most frequent diagnosis (20.1%) followed by astrocytoma (12.9%) and pineocytoma (9.9%). The single-entry approach allowed a correct histologic diagnosis in 88.7% of the examined cases. Summing up, concomitant ETV and TB represent a valuable option for the management of non-communicating hydrocephalus and the initial assessment of pineal region tumors. The histologic confirmation rate was 88.7% in the examined cohort, with only 10% of the biopsies yielding inconclusive results.

Abstract
BACKGROUND Many methods are reported for simultaneous endoscopic 3rd ventriculostomy and posterior 3rd ventricular biopsy with their pros and cons. We describe a novel single-entry two-stage rotational outside-in technique using the common 6° ventriculoscope and contrast this with others. TECHNIQUE Using a single burr hole, at the line extended from aqueduct through the larger foramen of Monro in parasagittal imaging, the ventricular endoscope is first inserted with 6° angled view anteroinferior, the tip of endoscope sheath just beyond the anterior part of the foramen, and ventriculostomy performed using flexible catheter's beveled cut end and balloon in a curvilinear trajectory using peripheral visualization. Keeping camera in the same orientation, it is then rotated 180° having 6° angled view postero-inferior, endoscope sheath traversing the posterior part of the foramen close to the posterior 3rd ventricular target, and biopsy obtained with rigid forceps. This technique overcomes some of the limitations of other methods by exploiting the flexible catheters and the rotational advantage of the 6° angle of the traditional ventriculoscope. CONCLUSION Our single burr hole two-stage rotational technique for simultaneous third ventriculostomy and posterior third ventricular biopsy seems to be an excellent alternative to other methods which can be used with both traditional 6° and greater angled ventriculoscopes without any significant deterrent.

Abstract
BACKGROUND Preoperative differential diagnosis of pineal region tumor can greatly assist clinical decision-making and avoid economic costs and complications caused by unnecessary radiotherapy or invasive procedures. The present study was performed to pre-operatively distinguish pineal region germinoma and pinealoblastoma using a clinicoradiomic model by incorporating radiomic and clinical features. METHODS 134 pineal region tumor patients (germinoma, 69; pinealoblastoma, 65) with complete clinic-radiological and histopathological data from Tiantan hospital were retrospectively reviewed and randomly assigned to training and validation sets. Radiomic features were extracted from MR images, then the elastic net and recursive feature elimination algorithms were applied to select radiomic features for constructing a fusion radiomic model. Subsequently, multivariable logistic regression analysis was used to select the clinical features, and a clinicoradiomic model incorporating the fusion radiomic model and selected clinical features was constructed for individual predictions. The calibration, discriminating capacity, and clinical usefulness were also evaluated. RESULTS Seven significant radiomic features were selected to construct a fusion radiomic model that achieved an area under the curve (AUC) value of 0.920 and 0.880 in the training and validation sets, respectively. A clinicoradiomic model that incorporated the radiomic model and four selected clinical features was constructed and showed good discrimination and calibration, with an AUC of 0.950 in the training set and 0.940 in the validation set. The analysis of the decision curve showed that the radiomic model and clinicoradiomic model were clinically useful for patients with pineal region tumor. CONCLUSIONS Our clinicoradiomic model showed great performance and high sensitivity in the differential diagnosis of germinoma and pinealoblastoma, and could contribute to non-invasive development of individualized diagnosis and treatment of patients with pineal region tumor.

Abstract
Background: Pineal tumors are very rarely encountered, with an incidence of <1% of intracranial lesions in adults. Life-threatening hydrocephalus due to obstruction of the third ventricle can result from the location of these tumours. Endoscopic third ventriculostomy (ETV) and tumor biopsy is a safe and feasible strategy, particularly if the tumor appears benign. This mitigates the high risks of uncontrollable venous bleeding from open and stereotactic biopsies. While typically performed using either ipsilateral single or dual bur holes, the location of the tumor may require modifications to the standard endoscopic techniques. Case Description: A 55-year-old male presented with signs of intracranial hypertension and was found to have obstructive hydrocephalus due to a pineal tumour. The tumour displayed a right-sided dominance when the pre-operative imaging was assessed, which would risk forniceal injury if biopsied via a right-sided burr hole. Craniometric measurements revealed a superior trajectory to the tumour via the left foramen of Monro. A biforaminal approach was performed, with a traditional ETV using a right coronal bur hole and biopsy via a left frontal bur hole. This minimized forniceal stretching and allowed a safe biopsy. Conclusion: The bi-foraminal approach has not been widely described in the literature but can potentially avoid morbidity with biopsy in patients with right-sided pineal tumours. We believe this technique should be considered, particularly in low-resource settings where neuroendoscopy is not commonly done, and where the use of ipsilateral single or dual-bur holes may lead to forniceal injury.

Abstract
BACKGROUND Endoscopic third ventriculostomy (ETV) has become a proven modality for treating obstructive and selected cases of communicating hydrocephalus. OBJECTIVE This review aims to summarize the indications, preoperative workup, surgical technique, results, postoperative care, complications, advantages, and limitations of an ETV. MATERIALS AND METHODS A thorough review of PubMed and Google Scholar was performed. This review is based on the relevant articles and authors' experience. RESULTS ETV is indicated in obstructive hydrocephalus and selected cases of communicating hydrocephalus. Studying preoperative imaging is critical, and a detailed assessment of interthalamic adhesions, the thickness of floor, arteries or membranes below the third ventricle floor, and prepontine cistern width is essential. Blunt perforation in a thin floor, while bipolar cautery at low settings and water jet dissection are preferred in a thick floor. The appearance of stoma pulsations and intraoperative ventriculostomography reassure stoma and basal cistern patency. The intraoperative decision for shunt, external ventricular drainage, or Ommaya reservoir can be taken. Magnetic resonance ventriculography and cine phase-contrast magnetic resonance imaging can determine stoma patency. Good postoperative care with repeated cerebrospinal fluid drainage enhances outcomes in selected cases. Though the complications mostly occur in an early postoperative phase, delayed lethal ones may happen. Watching live surgeries, assisting expert surgeons, and practicing on cadavers and models can shorten the learning curve. CONCLUSION ETV is an excellent technique for managing obstructive and selected cases of communicating hydrocephalus. Good case selection, methodical technique, and proper training under experts are vital.

Abstract
Background: The goal of this retrospective study is to present the first epidemiological data on pediatric supratentorial central nervous system (CNS) tumors in Lebanon and to review the various surgical management strategies used. Methods: We conducted a retrospective case series of all pediatric patients who presented with a supratentorial CNS tumor and underwent surgery at our institution between 2006 and 2016. We collected and analyzed demographic characteristics, tumor location, clinical manifestations, histopathology, and surgical management strategies and outcome, and discussed them after dividing the tumors as per location and in view of published literature. Results: Ninety-nine children were studied with a male-to-female ratio of 2.3:1 and a mean age of 8.5 years. The most common location was convexity (44%) and included low-grade and high-grade glial tumors, along with other miscellaneous lesions. The next location was sellar/diencephalic (34%), including craniopharyngiomas, hypothalamic/optic pathway/thalamic gliomas, hamartomas, and pituitary/Rathke’s cyst, where there was notable use of endoscopic techniques (21%). Tumors in the pineal region (13%) were tectal gliomas, germ cell tumors, and pineoblastomas and were mostly treated endoscopically. The last group was lateral intraventricular tumors (8%) and was mostly choroid plexus lesions and ependymomas. Overall, the surgical objective was achieved in 95% with mild/moderate complications in 17%. Conclusion: A variety of pathologies may affect the pediatric population in the supratentorial region. Different surgical strategies, including microsurgical and endoscopic techniques, may be employed to remove, debulk, or biopsy these tumors depending on their location, suspected diagnosis, prognosis, and the need for treatment of possible associated hydrocephalus.

Abstract
We present the case of a woman diagnosed with a teratoma adherent to the vaginal wall. The patient had been misdiagnosed with an ovarian teratoma 8 years previously at her local hospital, but no mass was found in the pelvic cavity during cesarean section. She therefore attended our institution for further examination. Transvaginal ultrasonography, magnetic resonance imaging (MRI), and computed tomography (CT) revealed a large mass on the left side at the bottom of the pelvis, near the side of the vagina, mainly composed of greasy and cystic elements. Gynecological examination showed the mass protruding into the left side of the vaginal wall. The patient therefore underwent vaginal wall incision. During surgery, we found a mass adherent to the vaginal wall, located on the left front of the rectum. Surgery was completed successful with no complications. This case highlights the need for careful preoperative evaluation of teratomas with unusual locations. MRI and CT may be useful for identifying the origin of the tumor and determining its relationship with the surrounding tissues. Surgery should be based on the characteristics and anatomical location of the tumor to minimize damage to other tissues and organs.

Lateral Temporal Approach for Image-Guided Stereotactic Biopsy of Pineal Region Tumors. World Neurosurg 2020; 147:144-149. [PMID: 33307256 DOI: 10.1016/j.wneu.2020.11.128] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2020] [Revised: 11/22/2020] [Accepted: 11/23/2020] [Indexed: 11/22/2022]
Abstract
BACKGROUND Biopsy of pineal region neoplasms is frequently accomplished by way of endoscopic transventricular access or using an image-guided, computer-assisted stereotactic approach. METHODS We evaluated a nonorthogonal lateral temporal approach for stereotactic biopsy of pineal region tumors as a variation of previously described stereotactic methods. Magnetic resonance imaging-guided frameless stereotaxy was used to plan and perform biopsies of pineal region tumors using a nonorthogonal trajectory extending from the superior or middle temporal gyri through the temporal stem, anterior to the atrium of the lateral ventricle, and posterior to the corticospinal tract. RESULTS All patients had an uncomplicated postoperative course and remained at neurologic baseline. No parenchymal or ventricular hemorrhage was present on postoperative scans. A tissue diagnosis was obtained in all patients. CONCLUSIONS This method appears to be a safe alternative to stereotactic biopsy using other trajectories and provides adequate tissue for definitive diagnosis.

Abstract
With the evolution of surgical techniques, endoscopy has emerged as a suitable alternative to many instances of more invasive methods. In this review article, we aim to discuss the endoscopic advancements, procedural details, indications, and outcomes of the most commonly practiced neuroendoscopic procedures. We have also summarized the uses, techniques, and challenges of neuroendoscopy in select neurosurgical pathologies.

The role of external ventricular drainage for the management of posterior cranial fossa tumours: a systematic review. Neurosurg Rev 2020; 44:1243-1253. [PMID: 32494987 DOI: 10.1007/s10143-020-01325-z] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2020] [Revised: 05/20/2020] [Accepted: 05/25/2020] [Indexed: 10/24/2022]
Abstract
Posterior cranial fossa tumours frequently develop hydrocephalus as first presentation in up to 80% of paediatric patients and 21.4% of adults, although it resolves after tumour removal in 70-90% and 96%, respectively. New onset hydrocephalus is reported in about 2.1% of adult and 10-40% of paediatric patients after posterior fossa surgery. There is no consensus concerning prophylactic external ventricular drainage (EVD) placement that is frequently used before posterior fossa lesion removal, as well in those cases without clear evidence of hydrocephalus. The aim of the study was to define the most correct management for patients who undergo posterior fossa tumour surgery, thus identifying cohorts of patients who are at risk of persistent hydrocephalus prior to surgery. A systematic review of literature has been performed, following PRISMA guidelines. Most of the studies reported CSF shunt only in the presence of hydrocephalus, whereas only a few authors suggested its prophylactic use in the absence of signs of ventricular dilatation. Predictive factors for postoperative hydrocephalus has been identified, including young age (< 3 years), severe symptomatic hydrocephalus at presentation, EVD placement before surgery, FOHR index > 0.46 and Evans index > 0.4, pseudomeningocele, CSF leak and infection. The use of pre-resection CSF shunt in case of signs and symptoms of hydrocephalus is mandatory, although it resolves in the majority of cases. As reported by several studies included in the present review, we suggest CSF shunt also in case of asymptomatic hydrocephalus, whereas it is not indicated without evidence of ventricular dilatation.

Endoscopic-assisted surgery versus microsurgery for pineal region tumors: a single-center retrospective study. Neurosurg Rev 2020; 44:1017-1022. [PMID: 32198566 DOI: 10.1007/s10143-020-01283-6] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2020] [Revised: 02/24/2020] [Accepted: 03/06/2020] [Indexed: 12/20/2022]
Abstract
Pineal region tumors are extremely deep-seated and surgically challenging. The exposure and visualization obtained by microscopic surgery are relatively limiting. The application of high-definition endoscopes has recently provided neurosurgeons with a much more magnified and clearer view of the anatomy in the pineal region. The present study was performed to compare endoscopic-assisted surgery (ES) with microsurgery (MS) for pineal region tumors. We retrospectively analyzed patients admitted to our hospital for treatment of pineal region tumors from January 2016 to June 2019. All patients consented to undergo tumor resection with ES or MS. We compared the extent of resection, postoperative rate of hydrocephalus, complications, and outcomes between the two groups to estimate the safety and efficacy of ES. In total, 41 patients with pineal region tumors were divided into 2 groups: the ES group (n = 20) and MS group (n = 21). The rate of gross total resection was significantly higher in the ES than MS group (90.0% vs. 57.1%, p = 0.04). The rate of postoperative hydrocephalus was significantly lower in the ES than MS group (11.8% vs. 52.9%, p = 0.03). No significant differences were found in complications or the Karnofsky Performance Score between the two groups. ES can be used to safely and effectively achieve complete resection of pineal region tumors. In patients with obstructive hydrocephalus, ES provides a new way to directly open the aqueduct for cerebrospinal fluid recovery following tumor resection.
