Object The optimal management of malignant astrocytomas remains controversial, and the prognosis of these lesions has been dismal regardless of the administered treatment. In this study the authors investigated the surgical outcomes of cordotomy in patients with thoracic malignant astrocytomas to determine the effectiveness of this procedure. Methods Cordotomy was performed in 5 patients with glioblastoma multiforme (GBM) and 2 with anaplastic astrocytoma (AA). A Kaplan-Meier survival analysis was performed, and the associations of the resection level with survival and postoperative complications were retrospectively examined. Results Cordotomy was performed in a single stage in 2 patients with GBM and in 2 stages in 3 patients with GBM and 2 patients with AA. In the 2 patients with GBM, cordotomy was performed 2 and 3 weeks after a partial tumor resection. In the 2 patients with AA, the initial treatment consisted of partial tumor resection and subtotal resection combined with radiotherapy, and rostral tumor growth and progressive paralysis necessitated cordotomy 2 and 28 months later. One patient with a secondary GBM underwent cordotomy; the GBM developed 1 year after subtotal resection and radiotherapy for a WHO Grade II astrocytoma. Four patients died 4, 5, 24, and 42 months after the initial operation due to CSF dissemination, and 3 patients (2 with GBM and 1 with AA) remain alive (16, 39, and 71 months). No metastasis to any other organs was noted. Conclusions One-stage cordotomy should be indicated for patients with thoracic GBM or AA presenting with complete paraplegia preoperatively. In patients with thoracic GBM, even if paralysis is incomplete, cordotomy should be performed before the tumor disseminates through the CSF. Radical resection should be attempted in patients with AA and incomplete paralysis. If the tumor persists, radiotherapy and chemotherapy are indicated, and cordotomy should be reserved for lesions growing progressively after such second-line treatments.

Abstract Aim Reversal of hartmanns is still an operation associated with significant morbidity. Although various studies have tried to assess the best time for attempting reversal after the primary operation, there is still no consensus. The aim of our study was to look at our experience over the last three years to find any possible factors which determine the duration between primary operation and reversal and compare laparoscopic vs open approach. Methods Prospective cohort including consisting of patients who underwent hartmanns reversal in 3 years was analysed (January-2017 to December-2019). Data was collected retrospectively from clinical notes. Results Among the patients (n = 50) there was equal distribution of males (52%) and females (48%). Although the initial operation was open in 74% patients, reversal was attempted laparoscopically in 46% with a conversion rate of 43.4%. Median duration between initial operation and reversal was 433 days. There was no significant association between duration before reversal and patient comorbidities or the indication for the index procedure. Also there was no statistical difference in postoperative hospital stay or immediate postoperative morbidity between laparoscopic and open hartmanns reversal. Conclusion There was no difference in immediate postoperative outcomes between patients who had laparoscopic or open hartmanns reversal. There was no determining factor which made the surgeon prefer laparoscopic over open approach nor was there a difference in duration between primary operation and reversal based of patient factors or method of approach. Hence timing of hartmanns reversal and the method of approach still depends on surgeon preference and experience.

✓ Surgical resection of 13 operatively obscure arteriovenous malformations (AVM's) was accomplished with the assistance of intraoperative angiography, which was performed stereographically to provide three-dimensional orientation and was repeated until total resection of the AVM was confirmed. All films obtained were subtracted to improve clarity. The method presented here may be useful for the resection of all types of AVM. Only two patients had residual AVM after the initial operation. No complications attributable to angiography were noted.
