Gelfoam Padding, an innovative surgical technique improving the total resection rate of cystic gliomas.

Abstract Objective The cystic gliomas are the special type of malignant tumors in the brain and often lead to unsatisfied prognosis, but the microsurgical resection is still the most important treatment. However, they are difficult to be totally removed with craniotomy, especially for those who have flimsy cyst walls. Recently, we attempted to resect them via an innovative surgical technique, “Gelfoam Padding”, in order to improve the total resection rate of the tumors safely. Patients and methods Fifteen patients suffering intracerebral cystic gliomas underwent surgical intervention via “Gelfoam Padding” technique between 2015 and 2018, and the different histopathological results and their features of cyst walls were recorded. Then, the total resection rate of tumors as well as the complications after surgeries were analyzed to assess the applied value of this technique. Results All the patients were improved in the clinical symptoms after the operations. According to the intraoperative assessment and MRI examinations performed within 72 h after surgery, total resection of the tumor was achieved in all patients. Besides, there were no serious postoperative complications in these cases with this technique. Conclusion The cystic glioma with the flimsy wall was the best applied indication of “Gelfoam Padding” technique, which could not only improve the total resection rate of tumors, but also be safe for the patients.
