T1 carcinoma is often not recognized as such, and inappropriate endoscopic resection techniques are selected, resulting in positive (R1) or nonassessable (Rx) resection margins. Full-thickness resection has been proposed as an alternative to completion surgery. Gijsbers et al. compared oncological outcomes of both strategies. The main finding was that colorectal cancer recurrence was significantly higher in the full-thickness excision of the scar compared with the completion surgery group (9.0% vs 2.2%). However, metastasis-free survival and overall survival were not significantly different in both groups. The results of this study favor full-thickness excision of the scar as the first-line approach for Rx/R1-resected margins but otherwise low-risk tumors.

Direct-acting antiviral agents (DAAs) have modified the management of chronic hepatitis C virus (HCV) infection, including HCV-related cryoglobulinemic vasculitis (CryoVas). However, patients might experience vasculitis relapse, and no reliable predictors of CryoVas relapse after sustained virologic response (SVR) have been established. We aimed to describe HCV-CryoVas relapse rates and factors associated with it.

An international multicenter cohort where patients with HCV-CryoVas from Egypt, France, and Italy treated with DAA were analyzed retrospectively. Factors associated with relapse-free survival were evaluated in a multivariate-adjusted model.

Of 913 patients, 911 (99.8%) obtained SVR. After 35 months of the median follow-up, 798 patients (87.4%) had sustained remission of vasculitis, while 115 (12.6%) experienced CryoVas relapse. By the time of relapse, skin involvement was present in 100%, renal involvement in 85.2%, and peripheral neuropathy in 81.7%. Relapses were treated with glucocorticoidsfound.
Hydrocephalus is a complex issue characterized by increased intracranial pressure secondary to obstruction of cerebrospinal fluid flow and occasionally due to overproduction. As a result, the entity has challenges of different dimensions at the level of understanding and management.

A literature search, systematic review, and meta-analysis of eligible studies were conducted in the major databases. The literature review included relevant articles on hydrocephalus published until June 1, 2021 (no starting date), databases being the only limitation considering the broadness of the subthemes. Controversies themes were chosen among the literature, not including treatment dilemmas and hydrocephalus research. The further detailed search included these selected themes and an updated literature review on the subjects.

Controversies are a hallmark of incomplete science; most complex concepts harbor several debates at various levels. This article reviews controversies in hydrocephalus, offering some updates on popular discussions. It is not meant to be an exposition of the topics themselves but to collect the status quo of unresolved concepts in hydrocephalus.

As with most chronic and complex disorders, hydrocephalus welcomes controversy as a healthy discussion platform to exist until we understand the disorder to its minutest.

This review documents the evolution of the Vellore grading system for tuberculous meningitis and hydrocephalus (TBMH), its evaluation by different authors, and analyzes the need for further modification in light of the published literature.

Published literature was searched in PubMed and Google Scholar using the search terms, "tuberculous meningitis hydrocephalus" and "Vellore grading." The retrieved articles were reviewed by the author and the appropriate ones were chosen for inclusion in the study.

Vellore grade (1-4, with 1 being the best grade and 4 being the worst grade) was found to be the sole statistically significant factor associated with outcome following VP shunt or ETV in several studies. Additionally, Vellore grades also correlate with the likelihood of success following ETV. However, the use of response to external ventricular drainage (EVD) in managing Vellore grade 4 patients has remained contentious as a small but significant proportion of patients have a good outcome following shunt, irrespective of their response to the EVD. The latter findings suggest that grade 4 patients might not constitute a homogenous group. It is proposed that grade 4 be subdivided into grades 4a and 4b, which might help in prognostication and in surgical management of the hydrocephalus in patients with TBMH.

Vellore grading has proved its utility as a prognostic tool and can aid surgical decision-making. However, management of patients in grade 4 might be better rationalized with its division into grades 4a and 4b.

The natural history and treatment outcomes in adult patients with hydrocephalus is a broad and heterogeneous topic that encompasses the natural history of the various subtypes of adult hydrocephalus with or without treatment; their surgical operative results, including symptom improvements, treatment failure, short- and long-term complications, and reoperations; and morbidity, mortality, and patient-centered health-related quality of life (HRQoL).

The objective of this review is to present a current update on the natural history and treatment outcomes, including QoL, for adults with hydrocephalus with a focus on patients with idiopathic normal pressure hydrocephalus (iNPH). A nonsystematic review of relevant literature was summarized.

The natural history for untreated patients with iNPH is poor, with both increased mortality and morbidity. It is strongly recommended that practitioners follow established guidelines to select patients with suspected iNPH while using objective measures of gait, balance, an(ETV) to treat patients with iNPH. There is limited data regarding HRQoL in patients with iNPH. In addition to objective measures of outcomes focused on gait and cognition, it is equally important for future studies to assess patient-centered subjective measures of HRQoL.
Endoscopic Third Ventriculostomy (ETV) is increasingly being accepted as the treatment of choice in place of Ventriculo-Peritoneal (VP) Shunt for hydrocephalus. However, their differences in cognitive and Quality of Life (QOL) scores have not been studied much in children.

To compare the outcome, cognitive function, and QOL between ETV and VP shunt.

Patients of non-tumor hydrocephalus treated with ETV or/and VP shunt underwent cognitive assessment (using modified child MMSE standardized as per the age group) and QOL (using PedsQL as per the age group in Physical, Emotional, Social, and School Functioning domains) in addition to the outcome of not requiring additional intervention.

Out of 139 patients, there were 29 infants and 40 children upto 14 years. Among these children, ETV was the primary intervention in 45, VP shunt in 24, and could be studied for a mean follow-up of 1.7 years. Though ETV required lesser additional intervention than VP shunt (19.2% vs. 28.6%) in toddlers and older children, there was no overall significant difference. Subnormal cognitive scores were noted in 25%, 40%, and 50% after ETV, single shunt procedure, and multiple shunt procedures, respectively, with no statistically significant difference. Among the different domains of QOL, the child reported scores in the social domain were significantly better after ETV than VP shunt (475[+13] vs. 387[+43], P value 0.03), whereas most other scores were non-significantly better following ETV.

Patients who underwent ETV show a trend for better clinical outcome, cognitive function, and QOL with significantly better child-reported QOL scores in the social domain.

Shunt infection is the most significant morbidity associated with shunt surgery. Based on the existing literature for the prevention and management of shunt infection, region and resource-specific recommendations are needed.

In February 2020, a Guidelines Development Group (GDG) was created by the Indian Society of Paediatric Neurosurgery (IndSPN) to formulate guidelines on shunt infections, which would be relevant to our country and LMIC in general. An initial email survey identified existing practices among the membership of the IndSPN, and eight broad issues pertaining to shunt infection were identified. Next, members of the GDG performed a systematic review of the literature on the prevention and management of shunt infection. Then, through a series of virtual meetings of the GDG over 1 year, evidence from the literature was presented to all the members and consensus was built on different aspects of shunt infection. Finally, the guidelines document was drafted and circulated among the GDG for final at will provide a useful reference to neurosurgeons not only in India but also in other low and middle income countries. These guidelines need to be updated as and when new evidence emerges.
Hydrocephalus is an abnormal excessive accumulation of cerebrospinal fluid (CSF) in the cavity and spaces of the brain. Endoscopic third ventriculostomy (ETV) has been an established treatment modality for congenital hydrocephalus. However, in very young infants, the results are challenging. In our study, we have evaluated whether ETV really offers an acceptable complication-free postoperative course.

To study the complication and mortality rate in infants having congenital hydrocephalus treated with ETV.

This is a single-center prospective study conducted at the Department of Neurosurgery, K. G. M. U, Lucknow, from January 2019 to February 2020. We studied 40 infants presenting with clinical and radiological features suggestive of congenital hydrocephalus. Follow-up was done at the first, third, and sixth months after discharge.

Nineteen infants (47.5%) required a second CSF diversion procedure at 6 months of follow-up. The failure rate was significantly higher in infants less than 3 months of age (Psurgery should be immediately considered.
The global burden of pediatric hydrocephalus is high, causing significant morbidity and mortality among children especially in low- and middle-income countries. It is commonly treated with ventriculoperitoneal shunting, but in recent years, the combined use of endoscopic third ventriculostomy (ETV) and choroid plexus coagulation (CPC) has enabled patients to live without a shunt.

We aim to give an overview of ETV+CPC for the treatment of hydrocephalus in infants, focusing on patient selection, perioperative care, and long-term follow-up.

We summarize observational studies and randomized trials on the efficacy and safety ETV+CPC, mainly from Uganda and North America. The equipment needs and operative steps of ETV+CPC are enumerated. At the end of the article, three illustrative cases of infants who underwent ETV+CPC with differing outcomes are presented.

The likelihood of success following ETV+CPC is the highest among infants older than 1 month, those with noninfectious hydrocephalus (e.g., aqueductal stenosis and myelomeningocele), and those previously without a shunt.
