Abstract
BACKGROUND Endoscopic ventricular surgery (EVS) shows overall reduced morbidity compared to open craniotomy, but carries, however, the risk for neurocognitive impairment caused by fornix-, hypothalamus-, and injuries other structures adjacent to the ventricular system. Objective or subjective neurocognitive impairment after EVS is rarely reported. The aim of this study was to assess the subjective neurocognitive outcome in patients undergoing EVS for various pathologies. METHODS We conducted a retrospective cohort study in adult patients undergoing EVS at our institution between 2010 and 2021. The primary outcome was subjective neurocognitive outcome after EVS measured by patient-reported outcomes (PROs). Secondary outcomes were objective neurocognitive outcome, return-to-work rate, subjective quality of life and satisfaction with surgery. Descriptive and comparative statistics were conducted for all outcome parameters. RESULTS Fifty-one patients (median age 48 years, 62.7% female) were included. Patients commonly presented with subjective neurocognitive impairment (54.9%) and hydrocephalus was the most common indication for surgery (54.9%). Worse long-term subjective neurocognitive outcome was observed in 5 (21.7%) patients while 18 (78.3%) patients improved. Worse long-term objective neurocognitive outcome was seen in 2 cases (10.5%), of which 1 patient became worse trough surgery while 15 (78.9%) patients improved. Improved subjective and objective neurocognitive outcome correlated in 73.8% of the cases (r = 0.363, P = 0.018). Return to work was possible for 70% of the patients and subjective quality of life was improved or unchanged in 88.1% of the patients. CONCLUSIONS Subjective neurocognitive outcome and quality of life improvement are often achieved after EVS and permanent neurocognitive impairment is rare. Further well-designed trials on subjective and objective neurocognitive outcome after EVS are warranted.

Abstract
PURPOSE The surgical approach for colloid cysts of the third ventricle mainly consists of endoscopic or microscopic approach but few studies compare the neurologic outcomes and complications related to the different approaches. We retrospectively reviewed our results after resection of colloid cysts of the third ventricle using endoscopic surgery (ES) compared to open microsurgery (OS). METHODS Fifty-one patients were included in the study of which 17 patients underwent ES. Colloid cyst size and Evans' index were evaluated on CT or MRI scans. Presenting symptoms, neurologic outcomes and complications were compared between the two groups and analysed using Fisher's exact test. Operative time and days of hospital stay were compared between the two groups, using independent sample t-test. The median follow-up time was 96 days and did not differ significantly between the groups. RESULTS Shorter mean operative time (p = 0.04) and fewer days of hospital stay (p < 0.01) were found in the endoscopic group compared to the open microsurgical group. Presenting symptoms, neurological outcomes and postoperative complications were similar in the two groups. CONCLUSIONS ES showed similar neurologic outcomes and complications compared to OS for colloid cysts of the third ventricle. ES showed significantly shorter operative times and hospital stays compared to OS.

Abstract
Introduction:The plasticity of the neural circuits after injuries has been extensively investigated over the last decades. Transcallosal microsurgery for lesions affecting the third ventricle offers an interesting opportunity to investigate the whole-brain white matter reorganization occurring after a selective resection of the genu of the corpus callosum (CC).MethodDiffusion MRI (dMRI) data and neuropsychological testing were collected pre- and postoperatively in six patients with colloid cysts, surgically treated with a transcallosal-transgenual approach. Longitudinal connectometry analysis on dMRI data and graph analysis on structural connectivity matrix were implemented to analyze how white matter pathways and structural network topology reorganize after surgery.ResultsAlthough a significant worsening in cognitive functions (e.g., executive and memory functioning) at early postoperative, a recovery to the preoperative status was observed at 6 months. Connectometry analysis, beyond the decrease of quantitative anisotropy (QA) near the resection cavity, showed an increase of QA in the body and forceps major CC subregions, as well as in the left intra-hemispheric corticocortical associative fibers. Accordingly, a reorganization of structural network topology was observed between centrality increasing in the left hemisphere nodes together with a rise in connectivity strength among mid and posterior CC subregions and cortical nodes.ConclusionA structural reorganization of intra- and inter-hemispheric connective fibers and structural network topology were observed following the resection of the genu of the CC. Beyond the postoperative transient cognitive impairment, it could be argued anterior CC resection does not preclude neural plasticity and may subserve the long-term postoperative cognitive recovery.

Colloid cysts: Neuropsychological outcome, quality of life and long-term control after endoscopic gross total resection. Clin Neurol Neurosurg 2021; 209:106951. [PMID: 34547641 DOI: 10.1016/j.clineuro.2021.106951] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2021] [Revised: 09/08/2021] [Accepted: 09/09/2021] [Indexed: 11/23/2022]
Abstract
BACKGROUND Endoscopy is increasingly being adopted for removing colloid cysts. However, the neuropsychological outcome and quality of life (QOL) have not been studied in detail. This study is to evaluate the efficacy of endoscopic excision on cognitive measures and QOL. METHODS Patients with colloid cysts larger than 7 mm, undergoing endoscopy were prospectively studied concerning clinico-radiology, cognitive parameters (age and education adjusted), extent of resection and recurrence. A cross-sectional QOL assessment was additionally performed on endoscopic patients in comparison with cases who underwent microsurgery or standalone ventriculo-peritoneal (VP) shunt. RESULTS A total of 22 endoscopic patients with a mean age of 34 years and a mean cyst diameter of 19 mm were studied. Gross total resection(GTR) could be achieved in all. Over a mean follow-up of 53.4 months, none had a recurrence, ventriculomegaly, or retreatment. Among neuropsychological parameters, digit span was the most affected before surgery. There was a broad-based improvement in the mean global cognitive score from 40.63(±10.4) at baseline to 50.25(±5.8) after endoscopy with maximum improvement in 'immediate recall.' The change in scores also had a significant inverse correlation with cyst size, with cysts larger than 18 mm, resulting in lower scores following endoscopy(R=-0.9, P=0.01). QOL was significantly influenced by visual and cognitive impairments and was better among endoscopic patients than similar microsurgery or VP shunt controls, with a significant difference in social and environmental domains(P=0.02). CONCLUSION Endoscopy is effective in achieving GTR and long-term control, with neuropsychological improvement correlated with cyst size. This is probably the first report to show QOL is influenced by cognitive parameters and is better following endoscopy than after microsurgery or VP shunt.

Abstract
The widespread use of MRI has led to the increasingly frequent diagnosis of pineal and colloid cysts. While most are small and incidental, do not require long-term monitoring and will never need treatment, they are a cause of patient anxiety and clinician uncertainty regarding the optimal management-particularly for larger cysts or those with an atypical appearance. Occasionally pineal cysts, and more commonly colloid cysts, cause hydrocephalus that requires urgent neurosurgical treatment. More recently the non-hydrocephalic symptomatic pineal cyst has been described in the neurosurgical literature but there is controversy over this entity and its management. This review addresses the difficulties in managing pineal and colloid cysts and provides a pragmatic framework for the practising clinician.

Arnaout MM, Elsamman AK. Perspectives on Endoscopic Transseptal Interforniceal Approach for Retroforaminal Colloid Cysts. World Neurosurg 2021; 152:e71-e80. [PMID: 33974983 DOI: 10.1016/j.wneu.2021.05.004] [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: 03/04/2021] [Revised: 04/30/2021] [Accepted: 05/03/2021] [Indexed: 11/19/2022]
Abstract
BACKGROUND Although the interforniceal approach with the preservation of the fornix is useful during the endoscopic approach for retroforaminal colloid cysts, it carries a significant risk of memory and cognitive difficulties. Because most reports have reported the endoscopic approach to colloid cysts through the foramen with little emphasis on retroforaminal cysts, the aim of this study was to investigate colloid cysts as a special entity with regard to their different characteristics and surgical approaches and outcomes. METHODS In this retrospective study, 12 patients with third ventricular colloid cysts with retroforaminal extensions were included. All patients underwent endoscopic transseptal interforniceal approach with tumor resection. The surgical technique was briefly described, and preoperative and postoperative data were evaluated. RESULTS Among the 12 patients included in this study, most of our patients were males. Average diameter of the colloid cyst was relatively large (average 22 mm). Gross total resection was achieved in 10 cases (83.3%). The stable images showed no local recurrence in the long-term follow-up period except in 1 case at the 28-month follow-up period. CONCLUSIONS Retroforaminal colloid cyst represents a unique entity that requires special attention to its mode of growth. The endoscopic approach for retroforaminal colloid cysts is nearly the same as that for foraminal cysts. It has a lower incidence rate of postoperative memory changes, lower chances of total resection, and lower incidence rate of hard contents. Moreover, sufficient knowledge on morbid anatomy is important to avoid fornix injury.

Neurocognitive Complications after Ventricular Neuroendoscopy: A Systematic Review. Behav Neurol 2020; 2020:2536319.

Abstract
In recent years, neuroendoscopic treatment of hydrocephalus and various ventricular pathologies has become increasingly popular. It is considered by many as the first-choice treatment for the majority of these cases. However, neurocognitive complications following ventricular neuroendoscopic procedures may occur leading mostly to amnesia, which might have a grave effect on the patient's quality of life. Studies assessing neurocognitive complications after ventricular neuroendoscopic procedures are sparse. Therefore, we conducted a systematic review assessing the available literature of neurocognitive complications and outcome after ventricular neuroendoscopy. Of 1216 articles screened, 46 were included in this systematic review. Transient and permanent neurocognitive complications in 2804 ventricular neuroendoscopic procedures occurred in 2.0% (n = 55) and 1.04% (n = 28) of the patients, respectively. Most complications described are memory impairment, followed by psychiatric symptoms (psychosyndrome), cognitive impairment not further specified, declined executive function, and confusion. However, only in 20% of the series describing neurocognitive complications or outcome (n = 40) was neurocognition assessed by a trained neuropsychologist in a systematic manner. While in most of these series only a part of the included patients underwent neuropsychological testing, neurocognitive assessment was seldom done pre- and postoperatively, long-term follow up was rare, and patient's cohorts were small. A paucity of studies analyzing neurocognitive complications and outcome, through systematic neuropsychological testing, and the correlation with intraoperative lesions of neuronal structures (e.g., fornix) exists in the literature. Therefore, the neurocognitive and emotional morbidity after ventricular neuroendoscopic procedures might be underestimated and warrants further research.
