ABSTRACT
Objective To analyze MRI findings and pathological data of intracranial solitary fibroma tumor(SFT)to improve the understanding of this disease and the level of imaging diagnosis.Methods MRI images and clinical pathological data of 6 patients with intracranial SFT confirmed by surgery and pathology were analyzed retrospectively.Results All tumors were located in the supratentorium,in which 4 cases were irregularly lobulated,2 cases were oval.All lesions were clear boundaries,and size 3.0-8.6 cm (an average of 6.3 cm).The tumor was located in the right fronto-perietral area in 1 case,cross of the frontal midline in 2 cases,cross of the occipital midline in 2 cases and cross of the cerebellum in 1 case.On T1WI,6 cases of tumor parenchyma showed slight low signal.On T2WI,4 cases of tumors showed mixed signal with the"Yin and Yang"sign,and peritumoral edema was showed in 4 cases, tortuous flow void blood vessels were showed in 5 cases.On FLAIR,mixed signal was showed.On DWI,slightly higher signal was showed.On MRI enhanced study,tumor parenchyma was significantly increased,in which 3 cases of T2WI low signal areas were significantly enhanced,cystic necrosis and edema were not enhanced,and 3 cases showed"dural tail sign".On pathological study, tumor cells were spindle-shaped,bundle and braided distribution,rich in collagen fibers.Immunohistochemistry showed CD34(+), CD99(+),Vim(+).1 case was malignant,and 1 case was potentially malignant.Conclusion MRI features of intracranial SFT have certain characteristics,it is difficult to be characterized qualitatively.MRI has obvious advantages in the relationship of tumor location, shape,range and its relationship with surrounding tissue.It has important clinical application value for the clinical operation plan and the residual or recurrence of tumor after operation.
ABSTRACT
Objective To discuss the clinical application of CT-guided localization of small pulmonary nodules (SPNs) by using double-hook-wire before the performance of video-assisted thoracoscopic (VATS) resection.Methods Before the performance of VATS resection,CT-guided localization by using doublehook-wire was carried out in 54 patients with SPNs (67 small pulmonary nodules in total) and CT-guided localization by using single-hook-wire was employed in 63 patients with SPNs(81 small pulmonary nodules in total).The location success rate and complication rate of the double-hook-wire technique and the singlehook-wire technique were calculated.Results The location success rate of CT-guided localization for SPNs by using double-hook-wire performed before VATS resection in 54 patients was 100％.The incidences of pneumothorax and hemorrhage were 29.6％ (16/54) and 48.1％ (26/54) respectively.In 63 patients receiving single-hook-wire technique,the location success rate for SPNs was 98.4％ (62/63).The incidences of pneumothorax and hemorrhage were 28.5％ (18/63) and 25.4％ (16/63) respectively.Conclusion CT-guided localization for SPNs by using double-hook-wire before VATS resection can reduce the risk of failure in positioning the hook-wire,and this technique is an important supplement for other localization techniques.
ABSTRACT
Objective: To review the clinical effect of early enteral nutrition in patients with carcinoma of esophagus after operation.Methods: Nutrient canal was indwelt through Fresubin(TP) was given through the nasal-intestinal tube in 120 cases with carcinoma of esophagus after operation.Results: The complications such as anastomotic leakage,lung infection and incisional infection in the patients receiving early enteral nutrition were much less than those in control group.No death occurred.The time for bowel function recovery was much shorter.Conclusion: Early enteral nutrition can promote the recovery of gastrointestinal function,improve the nutrition,decrease the occurrence of complications and raise the successful rate of operation in operative patients with esophagus carcinoma.
