ABSTRACT
A retrospective study was conducted based on the clinical data of 15 choledocholith patients after Billroth-Ⅱgastroenterestomy who were treated with endoscopic retrograde cholangio-pancreatography (ERCP) through colonoscopy or duodenoscopy.It showed that choledocholith removed by colonoscopy for patients with Billroth-Ⅱ gastroenterestomy can achieve comparable therapeutic effect,but this method can reduce the operation difficulty,shorten the operation time and significantly increase the success rate.
ABSTRACT
Purpose To analyze the relationships between glomerular filtration rate (GFR) measured by SPECT and renal parenchyma thickness and enhanced CT value measured by CT, and to explore predictive significance of CT in evaluating renal function of patients with hydronephrosis.Materials and Methods One hundred and fifteen patients diagnosed with unilateral hydronephrosis by ultrasound were retrospectively analyzed. GFR% (GFR percentage of affected kidney to the both kidneys) was measured by SPECT. CT% (percentage of affected renal parenchyma thickness to the both kidneys) and enhanced CT% (percentage of enhanced CT value of affected kidney to the both kidneys) were measured by pre- and post-contrast CT scan. According to GFR, the renal function was divided into mild-to-moderate impairment, severely impairment and non-function. Twenty-five volunteers were recruited as control group. CT%, enhanced CT% and GFR%among the four groups were compared, and the correlation of CT% and enhanced CT%with GFR% was analyzed to evaluated CT in predicting renal function.Results CT%, enhanced CT% and GFR% in mild-to-moderate impairment group was significantly greater than those in severely impairment group and non function group (F=20.24, 7.78 and 329.21,P<0.05). GFR% was positive correlated with CT% (r=0.58,P<0.05) and enhanced CT% (r=0.61,P<0.05). Area under curve (AUC) of CT% were 0.54, 0.79 and 0.83 for mild-to-moderate impairment, severely impairment and non-function, with sensitivity of 92.91%, 93.47%, 65.72%, and specificity of 35.33%, 59.47%, and 88.62%, respectively. AUC of enhanced CT% were 0.79, 0.89 and 0.96 for the three groups, with sensitivity of 97.51%, 80.02%, 97.66%, and specificity of 58.14%, 89.82% and 94.27%, respectively.Conclusion There was high correlation between renal function imaging by SPECT and CT in evaluating renal function of hydroneohrosis patients. Pre- and post-contrast CT scan can be used as complements in predicting renal function, and post-contrast CT with high accuracy.
ABSTRACT
Objective To explore and evaluate the effect of 32P and pinyangmycin injected in combination for the treatment of maxillofacial hemangioma. Methods The patients were randomly divided into three groups. The first group of patients was treated with 32P; 100 patients were enrolled in this group, of which 37 were male and 63 female. 32P dosage between 0.37 and 0. 74 MBq per cm3 was prepared together with 0.5 ml of 2 %lidocaine, and appropriate normal saline, and then the mixture was injected into hemangioma every two weeks. The second group was given pinyangmycin, and the third group received both 32P and pinyangmycin. The second group included 30 male and 60 female, and the third group 64 male and 136 female. The dose and frequency were given as the same to the first group. Results 88.5 % of patients were cured using both 32P and pinyangmycin, and the cure rate was 77.0 % and 71.7 % with either 32P or pinyangmycin. Conclusion These results prove that 32P and pinyangmycin injected in combination for the treatment of maxillofacial hemangioma is more effective than either 32P or pinyangmycin alone, and furthermore, the method is easy, safe and has less complications.
