ABSTRACT
Objective To explore the significance of surgical resection for the pineal region tumor,the extent of tumor resection,the surgical approaches and treatment measures of hydrocephalus.Methods Twentythree patients diagnosed of pineal region cancer were recruited for this study.Thirteen patients received ventriculo-peritoneal shunt(V-P),during which 7 cases received intraoperative end-plate colostomy.Two of the 13 cases received a second V-P procedure.Another 13 cases received operation by corpus callosum- septum-Dome Room-the third ventricle approach to remove the tumor; Eight cases underwent the tumor resection by suboccipital supratentorial approach (Poppen approach )and 2 cases underwent the tumor resection by the infratentorial cerebellar approach( Krause approach).Results Total tumor resection was performed in 11 cases,subtotal or major total resection in 8 cases and partial resection in 4 cases.Nine cases underwent postoperative radiotherapy alone,8 receiving radiotherapy plus chemotherapy,and 6 cases receiving neither radiotherapy nor chemotherapy.Two cases died during treatment.Conclusion Though it is not practicable to completely remove the germ cell tumor in patients with relatively large tumors,cerebrospinal fluid circulation pathways should be reestablished,including ventriculo-peritoneal shunt,colostomy from the end of the third ventricle to the end plate.If tumors are not too large,they would be easy to be removed.The effects on the surrounding brain tissue would not be much significant.If the connection of Ⅲ,V ventricles were normal,the patient may not need shunt or colostomy.Radiotherapy and chemotherapy can be given to this kind of patients after the surgery.To improve the efficacy,other types of tumors,expecially the benign tumors,should be totally removed.
ABSTRACT
Objective To compare the effectiveness of hyperbaric oxygen (HBO) therapy and normal pressure oxygen inhalation for lung infection in patients with severe brain injury and tracheotomy.Methods Sixty lung infection patients with severe brain injury and tracheotomy were stratified by age and Glasgow coma scale (GCS) score into an HBO group (30) and a conventional therapy group (30).Both groups were given treatments to reduce intracranial hypertension and protect the brain,surgery,antibiotics,and symptomatic and support therapy.In the conventional group the patients received oxygen therapy at normal oxygen pressure by tracheal cannula.In the HBO group,the patients received HBO therapy through self-made oxygen devices by the authors.The body temperature,cough and expectoration,respiratory sounds and white blood cell (WBC) count were compared between the groups.Results There were statistically significant differences in body temperature,cough and expectoration,respiratory sounds and the normalized time for the count and classification of WBC between the groups.Conclusion HBO had good treatment effectiveness for excretion and expectorant in lung infection patients with severe brain injury and tracheotomy.
