RESUMO
【Objective】 To compare the clinical efficacy of robot-assisted and open surgery in the treatment of renal carcinoma with inferior vena cava cancer thrombus, and to analyze the safety and feasibility of robot-assisted radical nephrectomy. 【Methods】 Clinical data of 55 patients surgically treated for renal carcinoma with Mayo Ⅰ-Ⅲ inferior vena cava tumor thrombus during Dec.2015 and Dec.2021 were retrospectively analyzed. Based on the operation methods, the patients were divided into the robotic surgery group (n=36) and open surgery group (n=19). The perioperative data, oncological results and survival of the two groups were compared. 【Results】 All operations were successful. The median operation time was 176 (IQR:137-234) min, and grade Ⅲ and above complications occurred in 9(16.4%) cases. The robotic surgery group had lower intraoperative blood loss [300 (IQR:200-625) mL vs.1 000 (IQR:600-1 184) mL] and blood transfusion ratio [(20/36) vs. (18/19)] than the open surgery group, but higher postoperative hemoglobin level[109(98-120) g/L vs. 90(84-100) g/L]. During a median follow-up of 26 (IQR:19-39) months, 19(34.5%) patients developed new metastases and 12(21.8%) patients died. The postoperative tumor-specific survival (HR=0.39, 95%CI:0.13-1.16, P=0.090) and overall survival (HR=0.71, 95%CI:0.22-2.23,P=0.554) were not significantly different between the two groups. 【Conclusion】 There are no significant differences in the incidence of postoperative complications, tumor-specific survival and overall survival between robot-assisted and open surgery for Mayo Ⅰ-Ⅲ inferior vena cava tumor thrombus, but the intraoperative blood loss in robotic group is lower than that in the open surgery group.
RESUMO
Objective:To report our technique and outcomes of robotic management of complex pheochromocytoma.Methods:Twelve patients with complex pheochromocytoma underwent robot-assisted surgery from May. 2016 to Sep. 2018. Four patients were male and eight patients were female. The mean patient age was 44 (range, 21-66) years. There were seven right adrenal tumors, two left adrenal tumors and three bilateral tumors. The mean tumor size was 7.8 (range, 2.5-16.0) cm. All surgeries were performed by transperitoneal approach. Three patients underwent synchronous surgery for bilateral pheochromocytoma.Results:All procedures were performed successfully without conversion to open surgery. The mean operative time was 108 (range, 50-195) min and mean blood loss was 105 (range, 20-400) ml. The average postoperative indwelling time of drainage tube was four (range, 3-5) days. The mean postoperative hospital stay was 8.5 (range, 5-23) days. Histopathologic examination of specimen revealed pheochromocytoma arising from adrenal gland. There were no recurrences or metastatic events during the follow-up of 5 to 35 months.Conclusion:Robotic assisted surgery is safe and effective for management of complex pheochromocytoma and provides significant advantages with regard to less blood loss and shorter postoperative hospital stay.
RESUMO
Objective: To study the relationship between mental health and achievement motivation of undergraduates. Method: 532 undergraduates completed SCL-90 and Academic Achievement Motive Scale. Results:17.29% subjects had mental problems. Undergraduates had higher score in self-oriented motive than society-oriented motive, while the score of SCL-90 correlated positively with score in society-oriented motive. In students with poor academic achievement, the score of SCL-90 negatively correlated with score in self-oriented motive. Conclusion:Society-oriented motive had negative influence on mental health of undergraduates and in those with poor academic achievement, poor mental health positively correlated with lower self-oriented motive.
