ABSTRACT
Objective To investigate the feasibility and effect of synchronization imaging technology of 64-slice spiral CT on urography and angiography(CTUA).Methods 36 adult patients with urinary symptoms that apply for the conventional CTU were selected. Exclusion of iodine allergy,serious heart,liver and renal insufficiency,multiple myeloma,long-term diabetes,hyperthyroidism,etc.All patients were placed intravenous tube.100 mL iohexol(300 mg I/mL),divided into 40-60 mL and 35-40 mL,shall be injected respectively by interval about 25-45 min,and the corresponding injection rate was 2-2.5 mL/s and 3.5-4.0 mL/s.About 20-30 s after the second injection,scan urinary tract for a quick CTUA source image,then scan urinary tract again for a quick source image of CTU with 5 min delay.Two groups of data with reconstruction technique(including MPR,MIP,VR etc.)should be read and diagnosed independently and double-blinded by two doctors with many years'experience in CTU.They also need to evaluate the image quality of the kidneys,urinary tracts and renal vessels,and make a statistical analysis to judge whether the CTUA inspection technique was feasible and effective.Results CTUA was good at showing renal parenchyma,ureters,urinary bladder and renal vessels,and the display rate was respectively:0.83,0.916,1,0.806,by contrast,the conventional CTU was 0,0.972,1,0,accordingly.Compared with the conventional CTU,CTUA was obviously different from the CTU,especial in displaying the distinction between renal cortex and medulla,renal vessels,and CTUA was better than the conventional CTU.While in display of ureters and urinary bladder,they had no difference,both show good.Conclusion CTUA inspection technology is superior to the conventional CTU technique,and using a routine dose contrast medium with twice bolus injection and one scanning can provide information such as the kidneys,urinary tract and renal vessels.
ABSTRACT
Objective To explore the clinical efficacy and the influence of one-port,three-port and four-port laparoscopic cholecystectomy on quality of life in patients with laparoscopic cholecystectomy.Methods The clinical data of 60 patients with laparoscopic cholecystectomy were reviewed,and to compare the general condition,the influence of postoperative recovery and complications,disease of digestive system and the quality of life index in patients treated by one-port laparoscopic cholecystectomy(one-port group),three-port laparoscopic cholecystectomy(three-port group) and four-port laparoscopic cholecystectomy(four-port group).Results Although the time of operation in oneport group was longer than the other two groups (t =3.82,P ＜ 0.05 ; t =4.04,P ＜ 0.05),there were significant differ ences in the volume of the inoperative blood loss,hospital stay time,hospital costs in one-port group compared with the other two groups (P ＜ 0.05).There was no difference among the three groups in the incidence of postoperative complications (P ＞ 0.05).And when leaving hospital,the score of all dimensionalitis in the scale of Gastrointestinal quality of life index (CIQLI),containing the state of physiological function,state of daily life and social activities,psychological emotional state and quality of life of the total score were all higher than those in the other two groups (t =2.22,1.87,2.31,2.43,all P ＜ 0.05),and there was no difference between three-port group and four-port group(P ＞ 0.05).Conclusion Compared with the three-port laparoscopic cholecystectomy and four-port laparoscopic cholecystectomy,one-port laparoscopic cholecystectomy can reduce the inoperative blood loss,shorten hospitalization time and reduce their fee in hospital,and it also can effectively improve patients'quality of life,restore the patients'normal work and life in the shortest possible time.
