Aim: Intraoperative ultrasonography is an accessible and cost-effective monitoring technique that provides a simultaneous view with minimum risk. Despite these advantages, it is still not in use. This study aimed to identify whether the ultrasonography technique would be advantageous for both surgeons in the preoperative period and patient in the postoperative period in cases where intraoperative ultrasonography was used. Materials and Methods:This retrospective study included data of the cases (n=113) diagnosed with a brain tumor in Tekirdağ Namık Kemal University Hospital between January 01, 2015 and December 31, 2020. The cases operated without using ultrasonography (n=38) formed the control group (group 1), while the cases operated by using ultrasonography (n=75) formed the study group (group 2). In all cases selected randomly, the amount of bleeding during the operation, length of the operation and postoperative stay in the hospital, and residue tumor amount were compared. Data obtained were evaluated statistically. The results were presented in mean±standard deviation and/or percentage (frequency). The alpha significance value was accepted as <0.05 in intergroup comparisons of the data obtained by being evaluated in the 95% confidence interval. Results:The average age of the cases in group 1 was 56.7±139 years while it was 57.7±13.2 in group 2. In intergroup comparisons, there was no statistically significant difference (p>0.05) between age (p=0.61), gender (p=0.74), and size of the tumor (p=0.27). It was observed that the average length of the operations of the cases in group 2 was shorter than that of group 1 (p=0.03), and this result was statistically significant (p<0.05). It was reported that the amount of bleeding of the cases in group 2 was also statistically significant (p<0.05) as against group 1. The gross total resection rate of cases in group 1 was calculated as 73.7% while it was 89.3% in group 2. It was understood that the amount of residue in group 2 compared to group 1 was statistically less (p<0.05) in a significant way (p=0.03). In addition to all these, it was found that the length of stay in group 2, which included cases operated with ultrasonography, was shorter than in group 1, which included cases operated without using ultrasonography (p=0.01). Conclusion:The use of intraoperative ultrasonography helps the surgeon by identifying resection margin and revealing the relationship between surrounding neural and vascular structures, thus increasing surgical safety. At the same time, the use of ultrasonography decreases the length of operation, amount of bleeding, and length of stay in the hospital, and increases gross total resection rates.

“…However, it was the development and application of real-time grey-scale US imaging technology that really provided an impetus to IOUS. The use of ultrasound to achieve maximally safe resection of brain tumors has been implemented since the 1980s [ 9 ]. In the pre-MR era, US (2-dimensional (2D) B-mode grey-scale US) imaging became a routinely-used adjunct in the neurosurgical operating room.…”

Maximal safe resection represents the gold standard for surgery of malignant brain tumors. As regards gross-total resection, accurate localization and precise delineation of the tumor margins are required. Intraoperative diagnostic imaging (Intra-Operative Magnetic Resonance-IOMR, Intra-Operative Computed Tomography-IOCT, Intra-Operative Ultrasound-IOUS) and dyes (fluorescence) have become relevant in brain tumor surgery, allowing for a more radical and safer tumor resection. IOUS guidance for brain tumor surgery is accurate in distinguishing tumor from normal parenchyma, and it allows a real-time intraoperative visualization. We aim to evaluate the role of IOUS in gliomas surgery and to outline specific strategies to maximize its efficacy. We performed a literature research through the Pubmed database by selecting each article which was focused on the use of IOUS in brain tumor surgery, and in particular in glioma surgery, published in the last 15 years (from 2003 to 2018). We selected 39 papers concerning the use of IOUS in brain tumor surgery, including gliomas. IOUS exerts a notable attraction due to its low cost, minimal interruption of the operational flow, and lack of radiation exposure. Our literature review shows that increasing the use of ultrasound in brain tumors allows more radical resections, thus giving rise to increases in survival.

In many clinics, intraoperative sonography is used as a routine method in general surgery as well as in neurosurgery. The availability of sterilizable applicators in diverse shapes and sizes enables the optimal approach to the site to be examined. In processes involving the liver, the pancreas, the kidneys, or the brain, ultrasonic examination, together with an exact topographic localization, proved to be helpful in determining the dimensions of an altered structure. In patients with colorectal carcinoma, the discovery of metastases that had not been previously detected by percutaneous sonography proves the necessity of regular intraoperative ultrasonic examination to augment staging accuracy in tumor surgery.
