Objective To evaluate the diagnostic value of high frequency ultrasound in sebaceous gland carcinoma of eyelid (SC).Methods The ultrasonic characteristic for 11 cases with eyelid SC were respectively analyzed by using 13 MHz high frequency ultrasound and 22 MHz ultra-high frequency ultrasound.Results Through 13 MHz high frequency ultrasound,in 7 patients who exhibited Pagetoid invasion the lid shin thickness of tumor side displays no significant alteration in a comparison with normal side.Furthermore,the color Doppler flow imaging (CDFI) evealed a branch-like blood flow surrounding the masses in all cases,but the blood flow of seven patients with Pagetoid invasion had no difference compared with the healthy side.On 22 MHz ultra-high frequency ultrasound examination,slit-like low echo was found in 9 ;transition zone of tumor infiltration can be identified in 9 ; the echo of tumors with Pagetoid invasion was lower than the healthy side and the skin thickness of tumors with Pagetoid invasion was thicker (0.6 ±0.1) mm than the healthy side.CDFI revealed that mesh-basket like blood flow was rich in all patients,the small branch blood vessels arrived at subcutaneous,and vasa vasorum were found in some patients.The region with Pagetoid invasion was rich in blood flow.The sonography findings on 13 MHz and 22 MHz high frequency ultrasound examination were compared with chisquare test.There were significant differences on homogeneous echo,slit-like low echo,transition zone of tumor infiltration,infiltration skin thickness,blood distribution,central blood vessels,vasa vasorum,blood flow in the region with Pagetoid invasion (x2 =12.571,15.231,15.231,4.701,22.000,15.231,4.899,10.267,P＜0.05).Conclusions Slit-like low echo in the mass is a main finding of eyelid sebaceous gland cercinoma on the 22 MHz ultra-high frequency ultrasound.The ultra-high frequency ultrasound can accurately reveal the skin depth infiltrated by the eyelid sebaceous gland cercinoma and this method can provide solid guidance for clinical treatment strategies.
Résumé
Objective To compare the clinical curative effect and the pros and cons of microwave intracavitary minimally invasive treatment and traditional operation for varicose veins in lower extremities.Methods(Treatment) group:The varicosities of greater saphenous vein were treated by microwave coagulation intracavitary treatment together with injection coagulation treatment of its tributaries. Control group:The varicosities of(greater) saphenous vein were treated by traditional operation.Results Treatment group was better than control group in improvement of symptoms,cosmetic effect of diseased limb,operation time,amount of blood loss,length of hospital stay,and complications of operation.Conclusions Microwave coagulation intracavitary treatment of varicose veins in lower extremities has more advantages,such as minimally invasive,little pain,quick recovery,good cosmetic effect,better result,fewer complications,and simplicity of operation.
Résumé
Objective To study the effect of applicaton of the implanted artificial defecation control device (IADCD) in patients with lower rectal cancer. Methods The "radical resection aiming at achieving automatically controlled defecation" was performed in 32 patients with lower rectal cancer, On the basis of Mile's operation, the IADCD was implanted in those patients. Postoperatively, the defection control, psychological effect of the defecation mode on the patients, complications and adverse effects were observed. Results In treatment group (32 cases), satisfactory defecation control was achieved in 31 cases 1 month after the operation, and in another case 2 month after operation, and no obvious complications and untoward effects. In control group(16 cases), 8 cases had 1～2 times formed stool 3 months after operation, 4 cases achieved 6 months after the operation. Conclusions For patients with lower rectal cancer, the "radical resection aiming at achieving automatically-controlled defecation" could achieve the complete resection of lower rectal tumor and near to normal defecation without obvious untoward effects.
