Efficacy of the Danish epilepsy surgery programme.

Area of Science:

• Neurology
• Neurosurgery
• Epileptology

Background:

• Approximately one-third of epilepsy patients remain seizure-free with optimal medical treatment.
• Epilepsy surgery is a recognized option for selected patients with drug-resistant focal epilepsy.

Purpose of the Study:

• To report the outcomes of the Danish epilepsy surgery program between 2009 and 2014.
• To evaluate the effectiveness and safety of epilepsy surgery in drug-resistant epilepsy patients.

Main Methods:

• A retrospective analysis of 169 consecutive patients undergoing epilepsy surgery at Rigshospitalet.
• Data collected from digital patient records, with 1-year follow-up for 164 patients.

Main Results:

• 65% of patients achieved Engel I outcome (free from disabling seizures) at 1-year follow-up.
• Medial temporal lobe epilepsy surgery showed 70% Engel I and 56% Engel IA outcomes.
• Serious complications were rare, though 12% of MTLE patients developed de novo depression.

Conclusions:

• The Danish epilepsy surgery program outcomes are consistent with international findings.
• Epilepsy surgery is generally safe with infrequent serious complications.
• Early referral for epilepsy surgery evaluation is advised for drug-resistant epilepsy patients.
