BACKGROUND: In recent years, temporal lobe encephalocele has become more common in patients with focal drug-resistant epilepsy. Despite available experience, there are still no clear recommendations for choosing the extent of surgery in these patients. OBJECTIVE: To evaluate the effectiveness of diagnosis and surgical treatment of focal drug-resistant epilepsy associated with temporal lobe encephalocele. MATERIAL AND METHODS: The study included 21 patients with focal temporal lobe epilepsy and temporal lobe encephalocele. All patients underwent continuous video-EEG monitoring and MRI of the brain. There were 12 (57.4%) selective encephalocele resections and 9 (42.6%) anterior temporal lobectomies. The median follow-up period was 31 months. RESULTS: The overall effectiveness of surgical treatment with postoperative Engel class I was 76% (16 cases). Selective encephalocele resection was followed by postoperative Engel class I in 10 patients (83%). There were 6 (67%) patients with similar outcomes after temporal lobectomy. Mean volume of resected tissue adjacent to encephalocele was 8.3 cm3. CONCLUSION: Surgery is a highly effective treatment for patients with epileptic seizures following temporal lobe encephalocele. In our sample, favorable postoperative outcomes were achieved in 76% of patients (Engel class I). There were no significant differences in effectiveness between selective resection and temporal lobectomy. Further research is necessary for a clear protocol of surgical treatment of focal drug-resistant epilepsy associated with encephalocele.

[Pre-surgical Diagnosties in Patients with Intractable epilepsy]. / Predkhirurgicheskaia diagnostika u patsientov s farmakorezistentnoi épilepsiei.

PURPOSE: To conduct a systematic assessment of scientific publications devoted to pre-surgical examination of patients with intactable epilepsy. MATERIAL AND METHODS: We found, using PubMed and available Internet search tools, and analyzed 1.414 articles on pre-surgical diagnostics in patients with intractable epilepsy. RESULTS: Epilepsy is a chronic disorder caused by brain injury, which manifests as repeated epileptic seizures and is accompanied by a variety of personality changes. Mortality risks in the population of patients with uncontrolled intractable epilepsy significantly exceed those in the general population. Early onset of comprehensive treatment prevents pathological personality changes and reduces the risks of mortality. However, complete seizure control is not achieved in 30% of patients, and they develop pharmacoresistance later, which is the reason for considering these patients as candidates for surgical treatment. In the literature, many approaches to pre-surgical examination are described as each clinic has its own concept of pre-surgical diagnostics and its own approaches to surgical management. Based on the conducted analysis, we tried to summarize the received information and describe current ideas about pre-surgical examination of patients with intactable epilepsy. CONCLUSION: On the basis of analyzed literature, we performed a systematic assessment and the evaluated effectiveness of various approaches in the pre-surgical diagnostics of patients with intactable epilepsy.
