ABSTRACT
Objective To compare the clinical efficacy of abdominal ultrasound-guided endoscopic retrograde appendicitis therapy(ERAT)with laparoscopic appendectomy(LA)for acute uncomplicated appendicitis using propensity score matching.Methods The clinical data of 441 patients with acute uncomplicated appendicitis admitted to the Third People's Hospital of Yunnan Province from March 2020 to April 2023 were collected.The cases were classified based on the differences in surgical method and divided into the ERAT group(n = 30)and LA group(n = 411).The clinical efficacy of patients was compared between the two groups after reducing confounding bias by propensity score matching(PSM).Results After PSM,a total of 30 pairs of patients in the two groups were successfully matched,and the baseline data of the two groups met the requirements for comparability.At 24 hours after the operation,the ERAT group exhibited lower white blood cells,neutrophil counts,and C-reactive protein levels compared to the LA group,and these differences were statistically significant(P<0.05).There was no significant difference in the operation time and total effective rate between the ERAT group and the LA group(P>0.05).However,the ERAT group had lower intraoperative blood loss and shorter pain relief time compared to the LA group,and these differences were statistically significant(P<0.05).Conclusion Abdominal ultrasound-guided endoscopic retrograde appendicitis treatment is an effective,safe,and feasible technique with good prospects for the treatment of acute uncomplicated appendicitis.
ABSTRACT
BACKGROUND:In the research on acupuncture treatment for lumbar disc herniation,most acupuncture treatments are performed under CT guidance or without guidance.The precise control of the target site and the effective acupuncture location are not clear. OBJECTIVE:To observe the clinical effects of acupuncture at Jiaji points under ultrasonic guidance in treating lumbar disc herniation. METHODS:A total of 70 cases of lumbar disc herniation,36 males and 34 females aged 18-65 years old,were selected from Chinese PLA General Hospital and Third Affiliated Hospital of Beijing University of Chinese Medicine.They were divided into trial group and control group by random number table method,with 35 cases in each group.The control group received acupuncture at Jiaji points.The trial group received acupuncture at Jiaji points under ultrasonic guidance.The patients were treated once on the day of treatment and 4,7 days after treatment.Visual analog scale score,Oswestry disability index,Japanese Orthopaedic Association score,and MOS 36-Item Short-Form Health Survey(SF-36)were evaluated before and after treatment. RESULTS AND CONCLUSION:(1)Compared with before treatment,the visual analog scale scores of both groups were decreased after treatment(P<0.01).Compared with the control group,the visual analog scale scores of the trial group were decreased on days 2,3,6,7 of treatment and 1,2 weeks after the end of treatment(P<0.05,P<0.01).(2)Compared with before treatment,Oswestry disability index after treatment was decreased in both groups(P<0.01).Compared with the control group,Oswestry disability index of the trial group was decreased from days 1 to 7 of treatment and 1,2 weeks after treatment(P<0.01).(3)Compared with before treatment,the Japanese Orthopaedic Association scores of both groups were increased after treatment(P<0.01).Compared with the control group,the Japanese Orthopaedic Association scores of the trial group were increased on days 3,7 of treatment and 1,2 weeks after treatment(P<0.05,P<0.01).(4)Compared with before treatment,SF-36 scores in both groups were increased after treatment(P<0.01).There was no significant difference in SF-36 scores between the two groups after treatment(P>0.05).(5)These results show that acupuncture at Jiaji points has curative effect on lumbar disc herniation,and ultrasonic guidance could improve the clinical curative effect of acupuncture at Jiaji points for lumbar disc herniation.
ABSTRACT
@#Objective To summarize and analyze the preliminary clinical outcomes of the KokaclipTM transcatheter edge-to-edge mitral valve repair system for severe degenerative mitral regurgitation (DMR). Methods This study was a single-arm, prospective, single-group target value clinical trial that enrolled patients who underwent the KokaclipTM transcatheter edge-to-edge repair (TEER) system for DMR in the Department of Heart Surgery of Guangdong Provincial People's Hospital, Guangdong Cardiovascular Institute from June 2022 to January 2023. Differences in the grade of mitral regurgitation (MR) during the perioperative and follow-up periods were compared, and the incidences of adverse events such as all-cause death, thoracotomy conversion, reoperation, and severe recurrence of MR during the study period were investigated. Results The enrolled patient population consisted of 14 (50.0%) females with a mean age of 70.9±5.4 years. Twenty-eight (100.0%) patients were preoperatively diagnosed with typeⅡ DMR, with a prolapse width of 12.5 (11.0, 16.1) mm, a degree of regurgitation 4+ leading to pulmonary venous reflux, and a New York Heart Association cardiac function class≥Ⅲ. All patients completed the TEER procedure successfully, with immediate postoperative improvement of MR to 0, 1+, and 2+ grade in 2 (7.1%), 21 (75.0%), and 5 (17.9%) patients, respectively. Mitral valve gradient was 2.5 (2.0, 3.0) mm Hg. Deaths, thoracotomy conversion, or device complications such as unileaflet clamping, clip dislodgement, or leaflet injury were negative. Twenty-eight (100.0%) patients completed at least 3-month postoperative follow-up with a median follow-up time of 5.9 (3.6, 6.8) months, during which patients had a mean MR grade of 1.0+ (1.0+, 2.0+) grade and a significant improvement from preoperative values (P<0.001). There was no recurrence of ≥3+ regurgitation, pulmonary venous reflux, reoperation, new-onset mitral stenosis, or major adverse cardiovascular events. Twenty-two (78.6%) patients’ cardiac function improved to classⅠorⅡ. Conclusion The domestic KokaclipTM TEER system has shown excellent preliminary clinical results in selected DMR patients with a high safety profile and significant improvement in MR. Additional large sample volume, prospective, multicenter studies, and long-term follow-up are expected to validate the effectiveness of this system in the future.

Objective To assess the clinical safety and feasibility for ultrasound guided paravertebral block anesthesia of percutaneous nephrolithotomy.Methods Between December 2015 to June 2016,180 patients with renal or ureteral calculi were enrolled and evaluated with uhrasonography and CT scan.Of all the 180 patients,108 males and 82 females.Their mean age was 39 years (23-71 years).The clinical characteristics of the patients in each group,such as age,gender,BMI index,ASA status,mean arterial pressure and disease type had no significant differences (P ＞ 0.05).These patients were randomized into general anesthesia group (G group),combined spinal epidural anesthesia group (C group) and paravertebral nerve block anesthesia group (P group).G group:35 males and 25 females.Their mean age was (40.1 ± 11.8) years and BMI was (25.1 ± 3.8) kg/m2;Renal calculi 52 cases,ureteral calculi 8 cases,Average maximum stone diameter was (2.6 ± 0.8)cm.C group:38 males and 22 females.Their mean age was (39.7 ± 12.4) years and BMI was (24.6 ± 4.1) kg/m2;Renal calculi 54 cases,ureteral calculi 6 cases,Average maximum stone diameter was (2.4 ± 0.8) cm.P group:35 males and 25 females.Their mean age was (38.9 ± 12.7) years and BMI was (25.4 ± 4.0) kg/m2;Renal calculi 51 cases,ureteral calculi 9 cases,Average maximum stone diameter was (2.5 ± 0.7) cm.Periprocedural Vital signs,complications,the times of anal discharging gas and postoperative feeding,hospitalized day and expense in these three groups were evaluated.Results Major intraoperative or postoperative complications did not occur in all of the patients.Mean arterial pressure decreased during preoperative changing positions was observed in group G (mean decreased 8.8 mmHg)and group C (mean decreased 1.9 mmHg),with significant difference in intra-group (P ＜ 0.05).Postoperative nausea and vomiting was observed in 8 and 2 patients of group G and group P,respectively (P ＜ 0.05).Postoperative pain was observed in 2 and 7 patients of group C and group P,respectively (P ＞ 0.05).In addition,group P had early post operation feeding time [(6.4 ± 2.4) h],shorter hospitalized day [(4.5 ± 1.1) d] and lower hospitalized expense compared with other groups (P ＜ 0.05).Conclusions Ultrasound guided paravertebral block can provide safe and reliable surgical anesthesia for percutaneous nephrolithotomy.
ABSTRACT
Objective To evaluate the clinical application value of three-dimensional medical image guided ultrasound in the chemotherapy of huge hepatic hemangioma.Methods Seventy-six cases were enrolled in a randomized control study.All cases were randomly divided into two groups (group A and group B).In group A,all cases underwent treatment based on the traditional two-dimensional medical images.Under the assistance of three-dimensional medical image information,preoperative treatment planning was performed in group B.After puncture treatment,therapeutic efficacy was evaluated by color ultrasound during follow-up.Results For treating huge hepatic hemangioma (tumor diameter ≥ 10.0 cm),the insertion number and pingyangmycin dosage in the group B were less than those in the group A [(6.2± 0.5)times vs (9.3±0.6) times,t=24.467,P=0.035;(99.2±8.0) mg vs (148.8±9.6) mg,t=34.613,P=0.029].The success rate of first treatment in the group B was higher than that in group A [73.6％(28/38) vs 100％(38/38),x2=131.91,P=0.032].Conclusion For huge hepatic hemangioma,the three-dimensional medical image information can be applied to reduce the insertion number and anesthetics dosage,improving the success rate of first treatment and therapeutic effect.
