ObjectiveTo evaluate the effects of low-energy radial extracorporeal shock wave therapy (rESWT) combing with moisture therapy on traumatic bone/tendon exposed wounds, and seek the best treatment project. MethodsThirty-three patients with bone/tendon exposed wounds treated from July 2013 to July 2015 were randomly divided into trial group (n=17) and control group (n=16) according to the sequence of admission. Patients in the control group accepted moisture therapy with proper dressings to deal with the wounds, while those in the experiment group accepted both moisture therapy and rESWT therapy. Then, we compared the two groups in terms of the frequency and total times of changing dressings, healing time, healing rate and wound contraction rate. ResultsThe healing rate of both the two groups was 100%. The trial group was significantly less than the control group in the frequency of changing dressings (P<0.05). The healing time of the trial group was significantly shorter than that of the control group (P<0.05), and wound contraction rate was higher than the control group (P<0.05). ConclusionLow-energy rESWT can shorten healing time, decrease frequency of changing dressings and total time of treatment, and perform better than moisture therapy only.
Extracorporeal shock wave treatment is capable of providing a non-surgical and effective treatment modality for patients suffering from osteoarthritis. The major objective of current works is to investigate how the shock wave (SW) field would change if a bony structure exists in the path of the acoustic wave. Firstly, a model of finite element method (FEM) was developed based on Comsol software in the present study. Then, high-speed photography experiments were performed to record cavitation bubbles with the presence of mimic bone. On the basis of comparing experimental with simulated results, the effectiveness of FEM model could be verified. Finally, the energy distribution during extracorporeal shock wave treatment was predicted. The results showed that the shock wave field was deflected with the presence of bony structure and varying deflection angles could be observed as the bone shifted up in the z-direction relative to shock wave geometric focus. Combining MRI/CT scans to FEM modeling is helpful for better standardizing the treatment dosage and optimizing treatment protocols in the clinic.
ObjectiveTo investigate the effectiveness of extracorporeal shock wave therapy combined with platelet-rich plasma (PRP) injection in treatment of knee osteoarthritis (KOA) by prospective clinical study.MethodsBetween June 2015 and June 2018, 180 patients with KOA met the inclusion criteria were included in study and randomly allocated to group A (n=60), group B (n=60), and group C (n=60). The patients were treated with autologous PRP intra-articular injection in group A, extracorporeal shock wave therapy in group B, and extracorporeal shock wave therapy combined with autologous PRP intra-articular injection in group C, once a week and 5 times a duration of treatment. There was no significant difference in age, gender, disease duration, side of KOA, and Kellgren-Lawrence grading between groups (P>0.05). The pain and function of knee joint were assessed by visual analogue scale (VAS) score, Lequesne Index score, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, and knee joint activity before treatment and at 1, 3, and 5 weeks after the first treatment.ResultsThere were significant differences in VAS score, Lequesne Index score, WOMAC score, and knee joint activity between pre- and post-treatment in all groups (P<0.05). VAS score, Lequesne Index score, and WOMAC score gradually decreased with the prolongation of treatment time (P<0.05); but there was no significant difference in knee joint activity between different time points (P>0.05). There was no significant difference in VAS score, Lequesne Index score, WOMAC score, and knee joint activity between groups before treatment (P>0.05); the scores of group C were superior to groups A and B (P< 0.05) at different time points after treatment; while the knee joint activities of 3 groups were similar (P>0.05).ConclusionThe extracorporeal shock wave therapy combined with PRP injection can relieve the pain synergistically for KOA.
Pancreatic duct stones are secondary to chronic pancreatitis while conventional medical treatment is always not effective. Due to the advantages of less trauma, simple operation, and fewer complications, since endoscopic retrograde cholangiopancreatography (ERCP) combined with extracorporeal shock wave lithotripsy (ESWL) was first used in the treatment of pancreatic duct stones in 1987, the treatment method has been continuously improved for more than 30 years, and has experienced the development process from being questioned to becoming the first-line treatment for pancreatic duct stones in multinational guidelines nowadays. However, with the rapid development of science and technology today, the method of ERCP combined with extracorporeal lithotripsy is also facing the challenges of many other treatment methods.
Objective To explore the value of endoscopic retrograde cholangiopancreatograph (ERCP) and extracorporeal shock wave lithotripsy (ESWL) in the treatment of pancreatic duct stones. Methods A retrospective collection of 28 patients with chronic pancreatitis and pancreatic duct stones admitted to the Department of Gastroenterology from January 2010 to August 2021 was performed. According to the treatment of patients, they were divided into ERCP direct stone extraction group and ESWL combined ERCP stone extraction group. We compared the treatment effects of the two groups of patients, including the success rate of stone extraction, postoperative complications of ERCP, postoperative symptom improvement, and so on. Results Among the 28 patients, 19 cases underwent ERCP direct stone extraction, and 9 cases underwent ESWL combined with ERCP stone extraction. In the ERCP direct stone extraction group, 7 cases (36.84%) were completely extracted, 1 case was partially extracted (5.26%), and 11 cases (57.89%) failed to extract and only placed stents and drained; 5 cases (26.32%) had elevated white blood cells at 6 hours postoperatively, C-reactive protein increased in 4 cases (21.05%), 3 cases (15.79%) were diagnosed as ERCP-related pancreatitis, and 2 cases (10.53%) were diagnosed as hyperamylaseemia. The abdominal pain symptoms were completely relieved in 14 cases (73.68%) during a follow-up period of 3 to 6 months. The body mass of 17 cases (89.47%) increased in the 6 months after stone extraction. ESWL combined with ERCP had complete stone extraction in 5 cases (55.56%), partial stone extraction in 3 cases (33.33%), and failure in stone extraction and only stent drainage in 1 case (11.11%). One case (11.11%) had elevated white blood cells at 6 hours postoperatively, and 1 case (11.11%) had elevated C-reactive protein . One case (11.11%) was diagnosed with ERCP-related pancreatitis. One case (11.11%) got abdominal pain and transient hematuria during ESWL, which resolved spontaneously 3 days later. After 3 to 6 months of follow-up, 9 patients (100%) had complete relief of abdominal pain symptoms, and the body mass of 9 patients (100%) increased in the 6 months after stone extraction. The stone clearance rate of the ESWL combined with ERCP stone extraction group was higher than that of the ERCP direct stone extraction group (P=0.033), but there was no statistically significant difference between the two groups in terms of ERCP-related complications, relief of abdominal pain, and weight gain (P>0.05). Conclusion ESWL combined with ERCP in the treatment of chronic pancreatitis complicated with pancreatic duct stone extraction is more effective than ERCP direct stone extraction.
