“…From this, we can conclude that rigid endoscopic biopsy of brain tumors has a high diagnostic yield. [ 1 ] The results are comparable to those of the previous reports describing other surgical techniques. [ 2 3 4 6 7 9 12 14 16 20 ]…”

Background:The authors report a continuous case series of navigation-guided rigid endoscopic biopsy via the transcortical route for intraparenchymal brain lesions to assess the feasibility and efficacy of the method.Methods:Thirty-four patients with intraparenchymal brain lesions found on neurovisualization underwent navigation-guided rigid endoscopic biopsy. Most of the preoperative diagnoses were glioma WHO Grade II–IV (16 cases) or malignant lymphoma (15 cases). Intraoperative photodynamic diagnosis and intraoperative pathological diagnosis were used in 28 and 29 cases, respectively. In 2 cases with small and deep lesions, intraoperative magnetic resonance imaging was used for confirming the accuracy of the biopsy point.Results:The sampling accuracy determined by postoperative imaging and the definitive diagnosis ratio were 94% (32 out of 34 cases) and 97% (33 out of 34 cases), respectively. There was no postoperative mortality. In 2 patients, mild postoperative permanent morbidity (5.9%), presumably related to this technique, was observed in the early cases in the current group (34 case series).Conclusion:The method was estimated as safe and feasible for diagnostic tissue sampling of intraparenchymal brain lesions.

“…It has been established that the volume of biopsy specimen and its integrity are of paramount importance. A small size of tissue retrieved through needle biopsy as well as its fragmentation is a common limitation for all needle biopsies, resulting in interpretation challenges 10,33,[36][37][38] . Larger tissue samples can ensure a better assessment of histologic architecture and facilitate molecular testing, which plays an increasingly important role in individualized medicine nowadays [39][40][41] .…”

The aim is to examine whether brain tissue samples obtained through needle biopsy are better for histopathological evaluation when obtained with defined vacuum pressure, a novel needle rotation method, and using different needle type - Laitinen or Nashold. Moreover the paper aims to answer the question: Does vacuum and mechanical injury resulting from different sampling methods damage the tissue specimen challenging the diagnosis?. Eight hundred biopsy specimens from fresh swine brains were obtained using Nashold and Laitinen brain biopsy needles through inner cannula cutting or needle rotation sampling at vacuum pressure, from 0 to 0.06 MPa. The specimen weight and tissue quality for microscopic assessment were evaluated using the Mair score. Rising aspiration pressure increased the biopsy sample weight. Needle rotation delivered larger biopsy samples than the standard method. Laitinen provided larger samples than the Nashold needle, with the same sampling method or vacuum pressure. A higher histopathological diagnostic quality of tissue was obtained with the Laitinen needle than with Nashold, with higher vacuum pressure than lower pressure and finally with needle rotation than the standard method. No tissue damage caused by higher suction pressure or method of tissue separation was documented. Brain tissue samples obtained through needle biopsy are better for histopathological evaluation when obtained with higher vacuum pressure, a novel needle rotation method and with Laitinen needle. Higher suction pressure and sampling methods did not cause tissue damage.

“…No significant difference between both stereotactic and endoscopic approaches was reported. And most studies report success more than 80% with endoscopic approach [9,18,19].…”

Background: Pineal region tumor is considered an ideal indication for endoscopic third ventriculostomy (ETV), with success rate up to 92%. The ultimate advantage is the ability to obtain tumor biopsy for histopathological diagnosis and for further treatment strategy plan design. Objectives: To investigate the safety considerations to minimize tumor biopsy-related bleeding, increase diagnostic accuracy, and establish a successful ETV procedure. Methods: Retrospective study including 25 patients of pineal region tumor with concomitant triventricular hydrocephalus. Preoperative planning to perform ETV and obtain tumor biopsy was achieved either through single more anteriorly located precoronal burr-hole (17 patients) or two separate burr-holes (eight patients). The patients' age ranged from 9 months to 65 years with a mean age of 26.5 years. Preoperative MRI brain with coronal T2-and sagittal T1-weighted images was used to design trajectory. Results: No significant intraventricular bleeding reported. A diagnostic tumor biopsy yield was successful in 22 patients. Ventriculoperitoneal shunt insertion was required in 1 patient failed to improve. Conclusion: Endoscopic tumor biopsy is relatively safe with high diagnostic yield that helps in management protocol plus shunt independent control of associated hydrocephalus.
