Psychosurgery

Psychosurgery

Psychosurgery, the surgical alteration or permanent removal of brain tissue to alleviate severe psychological conditions, stands as one of the most radical and controversial treatments in the history of mental health care. Its development and application have evolved significantly, marked by dramatic shifts in scientific understanding and ethical perspectives.

Summary

This summary is machine-generated.

Corpus callosotomy approaches offer similar seizure reduction for pediatric epilepsy. Posterior corpus callosotomy (PCC) may provide better drop attack control and lower disconnection syndrome (DCS) risk compared to anterior (ACC) or total (TCC) procedures.

Neurosurgery
Pediatric Neurology

Background:

Corpus callosotomy is a palliative surgery for intractable pediatric epilepsy.
Comparative data on anterior (ACC), posterior (PCC), and total (TCC) corpus callosotomy efficacy and complications are limited.

Purpose of the Study:

To evaluate and compare seizure reduction and postoperative complications of ACC, PCC, and TCC in pediatric intractable epilepsy.

Main Methods:

Systematic review of 66 studies (1349 patients) following PRISMA guidelines.
Meta-analysis of seizure reduction (Engel/ILAE classifications, seizure frequency score) and complications (disconnection syndrome [DCS], hydrocephalus, mortality).
Random-effects meta-analysis and subgroup comparisons between ACC, PCC, and TCC.

Main Results:

No significant difference in overall seizure reduction (Engel score 0 or 1) across ACC, PCC, and TCC.
PCC demonstrated superior reduction in drop attacks (92%) compared to ACC (52%) and TCC (58%).
PCC had the lowest DCS incidence (0%), followed by ACC (9%) and TCC (20%). Hydrocephalus and mortality rates were very low across all approaches.

Conclusions:

All corpus callosotomy techniques effectively reduce seizures in pediatric intractable epilepsy.
Posterior corpus callosotomy (PCC) may be preferable for drop attack control and has a lower risk of disconnection syndrome (DCS).
Total corpus callosotomy (TCC) is associated with the highest DCS incidence, highlighting the need for standardized reporting to clarify complication variations.
