ABSTRACT
Objective: To explore the clinical efficacy of ultrasound-guided local injection in treatment of rheumatoid arthritis (RA) patients with hand and wrist tenosynovitis. Methods: Totally 62 RA patients with hand and wrist tenosynovitis were randomly divided into ultrasound-guided injection (USGI) group (n=37) and conventional blind injection (CBI) group (n=25) and underwent USGI or CBI of betamethasone and lidocaine mixture, respectively. The ratio of adverse effect during the therapeutic process was compared between the two groups. Before treatment and 2, 4 and 12 weeks after treatment, the pain visual analogue scale (VAS), disease activity score in 28 joints (DAS28), gray scale ultrasound (GSUS) and power Doppler ultrasound (PDUS) scores, as well as therapeutic efficiency were compared between the two groups. Results: The ratio of adverse effect of USGI group was 2.70% (1/37), lower than that of CBI group (5/20, 20.00%; P=0.03). VAS and DAS28 scores of USGI group 4 and 12 weeks after treatment were lower than those in CBI group (all P<0.01). PDUS scores of USGI group 2, 4 and 12 weeks after treatment were lower than those in CBI group (all P<0.01), respectively, while GSUS score of USGI group was lower than that of CBI group 12 weeks after treatment (P<0.01). The efficiency of USGI group 4 and 12 weeks after treatment was higher than that in CBI group (both P<0.05). Conclusion: Ultrasound-guided local injection is safe and efficient in treatment of RA patients with hand and wrist tenosynovitis.
ABSTRACT
Objective The aim of this study was to explore the value of ultrasound in the diagnosis of Lemmel syndrome. Methods Ultrasound images of 36 patients with Lemmel syndrome confirmed by ERCP or surgery were retrospectively analyzed, and the image′s feature of ultrasound was explored. Results The ultrasound feature of Lemmel syndrome was showed as cystic protuberance from lesser curvature of duodenum, and three types of ultrasound characteristics were found: hyperechogenicity of gas, solid-cystic echogenicity full filled with fluid and inhomogeneous echogenicity full filled with food residue. The presence of hyperechogenicity (24 cases), solid-cystic echogenicity (8 cases), inhomogeneous echogenicity (4 cases) were found in 36 patients with periampullary diverticulum, and the biggest diameter of periampullary diverticulum was 6 to 32 mm. All of the patients (36 cases) were with mechanical obstruction in the common bile duct, and 12 patients were found mild dilatation of the pancreatic duct. Conclusion Higher clinical application value of ultrasound has been found when ultrasound is used in the diagnosis of Lemmel syndrome.
ABSTRACT
Objective To discuss the application of cystic cavity flushing technique in percutaneous ethanol sclerotherapy for the thyroid colloid cysts.Methods A total of 49 patients with thyroid colloid cysts were randomly divided into the study group (n=33) and the control group (n=16).Patients in the study group received cystic cavity flushing treatment by using saline together with α-chymotrypsin,which was followed by percutaneous ethanol injection (PEI).Patients in the control group underwent simple aspiration of cyst fluid followed by PEI.The residual cystic volume,the effective rate and the untoward effects were calculated at one,3 and 6 months after the treatment,and the results were compared between the two groups.Results Striking difference in the changes of postoperative residual cystic volume existed between the study group and the control group.The effective rate of PEI in the study group was 93.9％,which was obviously better than 68.8％ in the control group,the difference between the two groups was statistically significant (P＜0.05).No untoward effect was observed during the performance of aspiration of cyst fluid and flushing of cystic cavity.Nevertheless,bad side effect occurred in PEI procedure in both the study group (6.1％) and the control group (8.3％),but the difference was not statistically significant (P=0.75).Conclusion For the treatment of thyroid colloid cysts,the use of aspiration of cyst fluid together with cystic cavity flushing technique by using saline combined with α-chymotrypsin is safe and reliable,it can improve the curative effect of subsequent PEI.
