Abstract PURPOSE The removal of brain tumors requires not only imaging information such as MRI and navigation systems, but also a variety of other information such as neurological function and biological information. To integrate this information, a novel operating room, “Smart Cyber Operating Theater (SCOT)”, which connects the medical devices in the operating room via a network has developed. In this SCOT, the intraoperative information is time-synchronized, recorded, and stored by the middleware “OPeLiNK”. Clinical experience of brain tumor surgery using OPeLiNK in our institute is reported. Methods Brain tumor surgeries performed at SCOT, which had been started since July 2018, was enrolled. In all surgeries intraoperative information was integrated by OPeLiNK. Surgical procedure was discussed between main surgeon and supervising surgeon in the Strategy Desk through OPeLiNK intraoperatively, if necessary. Clinical and radiological data from patients who underwent resection at SCOT were analyzed retrospectively. Results Sixty patients were involved. Histopathological diagnosis was glioma in 29 patients, pituitary adenoma in 29 patients, acoustic tumor in 1 patient and intravascular lymphoma in 1 patient. Intraoperative discussion with Strategy Desk through OPeLiNK was useful for not only surgeons but also for medical staff in operation room. Advice for extent of resection and craniotomy from Strategy Desk was conducted by OPeLiNK using conversation and drawing. Intraoperative comment was useful for postoperative review. OPeLiNK, which display multiple intraoperative information, was also used at postoperative conference. Conclusion We have reported clinical experience with OPeLiNK for brain tumor surgery in our institute. OPeLiNK was useful for not only sharing intraoperative information with doctors outside the operation room but also postoperative review and education for young doctors.

AbstractIntraoperative ultrasound (US) has been shown to possess great value in assessing tumor volume and localization, especially for primary resection of gliomas and metastatic lesions. Given that US is a technology that is highly user dependent, many surgeons have encountered problems with the usage of this technology, as well as interpretation of intraoperative US images, limiting its full potential. This article focuses on the basic knowledge a neurosurgeon must acquire to properly use and interpret intraoperative US to improve tumor localization and extent of resection during brain tumor surgery.

Seizure Rate

Object Seizures in the perioperative period are a well-recognized clinical entity in the setting of brain tumor surgery. At present, the suitability of antiepileptic prophylaxis in patients following brain tumor surgery is unclear, especially in those without prior seizures. Given the paucity of tumor-type and site-specific data, the authors evaluated the incidence of postoperative seizures in patients with convexity meningiomas and no prior seizures. Methods The authors identified 180 patients with no preoperative history of seizures who underwent resection of a convexity meningioma. Some patients received antiepileptic prophylaxis for 7 days postoperatively while others did not, based on the practice patterns of different attendings. The rates of clinically evident seizures in the first 3–4 weeks after surgery were compared. Results Patients who received antiepilepsy drugs (129 patients) did not significantly differ from those who did not (51 patients) in terms of age, sex, WHO tumor grade, extent of resection, rate of previous cranial surgery or radiation therapies, or use of preoperative embolization. There was a single new postoperative seizure in the entire cohort, yielding a new seizure rate of 1.9% in patients not on antiepileptic prophylaxis compared with 0% in patients on antiepileptics (p = not significant). Conclusions While it is thought that the routine use of prophylactic antiepileptics may prevent new seizures in patients undergoing surgery for a convexity meningioma, the rate of new seizures in untreated patients is probably very low. Data in this study call into question whether the cost and side effects of these medications are worth the small benefit their administration may confer.

OBJECTIVEThe authors sought to evaluate the utility of intraoperative MRI (ioMRI) during brain tumor excision in pediatric patients and to suggest guidelines for its future use.METHODSAll patients who underwent brain tumor surgery by the senior author at Boston Children’s Hospital using ioMRI between 2005 and 2009 were included in this retrospective review of hospital records and the neurosurgeon’s operative database. Prior to the review, the authors defined the utility of ioMRI into useful and not useful categories based on how the technology affected operative management. They determined that ioMRI was useful if it 1) effectively guided the extent of resection; 2) provided a baseline postoperative scan during the same anesthesia session; or 3) demonstrated or helped to prevent an intraoperative complication. The authors determined that ioMRI was not useful if 1) the anatomical location of the tumor had precluded a tumor’s total resection, even though the surgeon had employed ioMRI for that purpose; 2) the tumor’s imaging characteristics prevented an accurate assessment of resection during intraoperative imaging; 3) the surgeon deemed the technology not required for tumor resection; or 4) the intraoperative MR images were uninterpretable for technical reasons. Follow-up data provided another gauge of the long-term benefit of ioMRI to the patient.RESULTSA total of 53 brain tumor patients were operated on using ioMRI, 6 of whom had a second ioMRI procedure during the study period. Twenty-six patients were female, and 27 were male. The mean follow-up was 4.8 ± 3.85 years (range 0–12 years). By the criteria outlined above, ioMRI technology was useful in 38 (64.4%) of the 59 cases, most frequently for its help in assessing extent of resection.CONCLUSIONSIntraoperative MRI technology was useful in the majority of brain tumor resections in this series, especially in those tumors that were contrast enhancing and located largely within accessible areas of the brain. The percentage of patients for whom ioMRI is useful could be increased by preoperatively evaluating the tumor’s imaging characteristics to determine if ioMRI would accurately assess the extent of tumor resection, and by the surgeon’s preoperative understanding that use of the ioMRI will not lead to resection of an anatomically unresectable tumor. The ioMRI can prove useful in unresectable tumors if specific operative goals are defined preoperatively.

Abstract It is reported that the development of new perioperative motor deficits was associated with decreased overall survival despite similar extent of resection and adjuvant therapy. The maximum safe resection without any neurological deficits is required to improve overall survival in patients with brain tumor. Surgery is performed with various modalities, such as neuro-monitoring, photodynamic diagnosis, neuro-navigation, awake craniotomy, intraoperative MRI, and so on. Above all, awake craniotomy technique is now the standard procedure to achieve the maximum safe resection in patients with brain tumor. It is well known that before any treatment, gliomas generate globally (and not only focally) altered functional connectomics profiles, with various patterns of neural reorganization allowing different levels of cognitive compensation. Therefore, perioperative cortical mapping and elucidation of functional network, neuroplasticity and reorganization are important for brain tumor surgery. On the other hand, recent studies have proposed several gene signatures as biomarkers for different grades of gliomas from various perspectives. Then, we aimed to identify these biomarkers in pre-operative and/or intra-operative periods, using liquid biopsy, immunostaining and various PCR methods including rapid genotyping assay. In this presentation, we would like to demonstrate our surgical strategy based on molecular and functional connectomics profiles.
