Awake Surgery for Right Frontal Lobe Glioma: Preserving Emotional Recognition and Facilitating Early Return to Work.

BACKGROUND/AIM: Many glioma patients struggle to return to work after surgery because of higher brain dysfunction. Although the right frontal lobe has historically been considered functionally silent, reports of performing awake surgery to evaluate higher brain functions in patients with tumors in this area have increased. We present two cases of patients who underwent awake surgery for malignant glioma in the right frontal lobe to preserve emotional recognition and facilitate an early return to work. CASE REPORT: Case 1 was a 48-year-old right-handed woman employed as a nursery school teacher and case 2 was a 21-year-old right-handed man employed in sales. Both had contrast-enhancing right frontal lobe tumors exhibiting high signal intensity on fluid attenuated inversion recovery imaging and underwent awake surgery. During the operation, cortical mapping was performed using the Reading the Mind in the Eyes, calculation, and motor tasks. Resection of sites involved in motor and emotional recognition functions was avoided. In case 1, all regions of high signal intensity were completely resected; in case 2, all regions exhibiting enhancement were resected. Both patients were discharged home without neurological deficits and returned to work within 21 days after surgery. CONCLUSION: It may be important to focus not only on overall survival and progression-free survival in glioma patients, but also on factors associated with life satisfaction, such as time to return to work after surgery and time until work becomes difficult. Awake surgery aimed at preserving higher brain functions is useful and may also improve life satisfaction.

Optimal tentative abdominal closure for open abdomen: a multicenter retrospective observational study (OPTITAC study).

BACKGROUND: Primary fascia closure is often difficult following an open abdomen (OA). While negative-pressure wound therapy (NPWT) is recommended to enhance successful primary fascia closure, the optimal methods and degree of negative pressure remain unclear. This study aimed to elucidate optimal methods of NPWT as a tentative abdominal closure for OA to achieve primary abdominal fascia closure. MATERIALS AND METHODS: A multicenter, retrospective, cohort study of adults who survived OA greater than 48 h was conducted in 12 institutions between 2010 and 2022. The achievement of primary fascia closure and incidence of enteroatmospheric fistula were examined based on methods (homemade, superficial NPWT kit, or open-abdomen kit) or degrees of negative pressure (<50, 50-100, or >100 mmHg). A generalized estimating equation was used to adjust for age, BMI, comorbidities, etiology for laparotomy requiring OA, vital signs, transfusion, severity of critical illness, and institutional characteristics. RESULTS: Of the 279 included patients, 252 achieved primary fascia closure. A higher degree of negative pressure (>100 mmHg) was associated with fewer primary fascia closures than less than 50 mmHg [OR, 0.18 (95% CI: 0.50-0.69), P =0.012] and with more frequent enteroatmospheric fistula [OR, 13.83 (95% CI: 2.30-82.93)]. The methods of NPWT were not associated with successful primary fascia closure. However, the use of the open-abdomen kit was related to a lower incidence of enteroatmospheric fistula [OR, 0.02 (95% CI: 0.00-0.50)]. CONCLUSION: High negative pressure (>100 mmHg) should be avoided in NPWT during tentative abdominal closure for OA.

Analysis of the Medial Opticocarotid Recess in Patients with Pituitary Macroadenoma Using Three-Dimensional Images.

OBJECTIVE: The medial opticocarotid recess (MOCR), which contains the lateral tubercular recess (LTR), is an important landmark for the cavernous internal carotid artery (ICA) and for accessing the parasellar and suprasellar regions. These microanatomic landmarks for endoscopic endonasal surgery can be observed using surgical simulation with three-dimensional images. The aim of this study was to analyze the MOCR in patients with pituitary macroadenoma using three-dimensional images. METHODS: We constructed three-dimensional computed tomography images of 20 patients with pituitary macroadenoma and 20 patients with unruptured aneurysms as a control. Using these images, we measured the distance between the left and right LTR, the midline and the unilateral LTR, and the left and right ICA. RESULTS: The distance between the left and right LTR was statistically longer in the pituitary adenoma group versus the control group. Tumor volumes were multivariate parameters for the distance between the left and right LTR, which was significantly longer in the group with tumor volumes >5 cm(3) versus the other groups. This distance was also significantly correlated with the distance between the left and right ICA. CONCLUSIONS: Pituitary macroadenomas expand the distance between the left and right MOCR together with the distance between the left and right ICA.
