经尿道国产1470nm激光汽化术治疗<30g小体积前列腺增生的临床体会

目的探讨经尿道国产1470nm激光汽化术治疗<30g小体积前列腺增生患者的安全性、有效性和远期并发症情况。方法回顾性研究2017年10月至2018年9月我院45例<30g小体积前列腺增生患者的临床资料,其中TURP组20例,1470 nm激光组25例。详细记录两组患者的临床资料、围手术期并发症和随访情况。结果45例患者手术均成功,术后平均随访时间12.6个月(9~16个月)。两组患者年龄、前列腺体积和IPSS、RUV、Qmax和QOL基线资料差异无统计学意义(P>0.05)。TURP组和1470 nm激光组患者术后3个月IPSS、RUV、Qmax和QOL均较术前改善(P<0.05),组间比较差异无统计学意义(P>0.05)。1470 nm激光组患者手术时间([48.6±13.6)min vs(56.8±11.7)min,P=0.038]、术后膀胱持续冲洗时间[(0.8±0.5)d vs(1.5±0.9)d,P=0.001]、导尿管留置时间([2.7±0.6)d vs(4.7±0.9)d,P<0.001]和住院时间([4.2±1.2)d vs(5.2±1.9)d,P=0.036]较TURP组患者明显缩短,术前术后血红蛋白浓度变化更小([5.5±2.4)g/L vs(11.6±2.7)g/L,P<0.01]。随访发现TURP组有2例出现尿道狭窄,1470 nm激光组无尿道狭窄病例发生。结论经尿道国产1470 nm激光汽化术治疗<30 g小体积前列腺增生安全有效,与传统TURP比较术中出血少,术后恢复时间更短,无尿道狭窄并发症发生,为BPH的个体化治疗提供了新的思路。     

Full‐Endoscopic Foraminotomy with a Novel Large Endoscopic Trephine for Severe Degenerative Lumbar Foraminal Stenosis at L5S1 Level: An Advanced Surgical Technique

To (i) introduce the technical notes of a novel full‐endoscopic foraminotomy with a large endoscopic trephine for the treatment of severe degenerative lumbar foraminal stenosis at L₅S₁ level; (ii) assess the primary clinical outcomes of this technique; (iii) compare the effectiveness of this full‐endoscopic foraminotomy technique and other previous techniques for lumbar foraminal stenosis. From January 2019 to August 2019, a retrospective study of L₅S₁ severe degenerative lumbar foraminal stenosis was performed in our center. All patients who were diagnosed with severe foraminal stenosis at L₅S₁ level and failed conservative treatment for at least 6 weeks were identified. Patients with segmental instability or other coexisting contraindications were excluded. A total of 21 patients were enrolled in the study. All patients were treated by full‐endoscopic foraminotomy using large endoscopic trephine. The visual analogue scale (VAS) and Oswestry disability index (ODI) were evaluated preoperatively and at 1, 3, 6 months, and 1 year after the surgery, and the modified MacNab criteria were used to evaluate clinical outcomes at the last follow‐up. There were 10 males and 11 females with a mean age of 66.38 ± 9.51 years. Five patients had a history of lumbar surgery. The mean operative time was 63.57 ± 25.74 min. The mean follow‐up time was 13.29 ± 1.38 months. The mean postoperative hospital stay time was 1.29 ± 0.56 days. The mean preoperative VAS score significantly decreased from 7.38 ± 1.02 to 2.76 ± 1.09 (t = 19.759, P < 0.01), 2.25 ± 1.02 (t = 21.508, P < 0.01), 1.60 ± 1.05 (t = 31.812, P < 0.01), and 1.45 ± 1.10 (t = 25.156, P < 0.01) at 1 month, 3 months, 6 months, and 1 year after the operation. The mean preoperative ODI score significantly decreased from 64.66% ± 4.91% to 30.69% ± 4.59% (t = 33.724, P < 0.01), 29.44% ± 4.50% (t = 32.117, P < 0.01), 24.22% ± 4.14% (t = 33.951, P < 0.01), and 22.44% ± 4.94% (t = 30.241, P < 0.01) at 1 month, 3 months, 6 months, and 1 year after the operation. At the last follow‐up, 19 patients (90.48%) got excellent or good outcomes. One patient suffered postoperative dysesthesia, and the symptoms were controlled by conversion treatment. One patient took revision surgery due to the incomplete decompression. There were no other major complications. Percutaneous endoscopic decompression is minimally invasive spine surgery. However, the application of endoscopic decompression for L₅S₁ foraminal stenosis is relatively difficult due to the high iliac crest and narrow foramen. Full‐endoscopic foraminotomy with the large endoscopic trephine is an effective and safe technique for the treatment of degenerative lumbar foraminal stenosis.     

Analgesic Effects of Ultrasound‐Guided Iliohypogastric/Ilioinguinal Nerve Block Combined with Lateral Femoral Cutaneous Nerve Block in Total Hip Arthroplasty via Direct Anterior Approach: A Retrospective Cohort Study

ObjectiveThis study aimed to explore the efficacy and safety of the combination of lateral femoral cutaneous nerve blocks (LFCNB) and iliohypogastric/ilioinguinal nerve blocks (IHINB) on postoperative pain and functional outcomes after total hip arthroplasty (THA) via the direct anterior approach (DAA).MethodsIn this retrospective cohort study, patients undergoing THA via the DAA between January 2019 and November 2019 were stratified into two groups based on their date of admission. Sixty‐seven patients received LFCNB and IHINB along with periarticular infiltration analgesia (PIA) (nerve block group), and 75 patients received PIA alone (control group). The outcomes included postoperative morphine consumption, postoperative pain assessed using the visual analogue scale (VAS), the QoR‐15 score, and functional recovery measured as quadriceps strength, time to first straight leg rise, daily ambulation distance, and duration of hospitalization. The Oxford hip score and the UCLA activity level rating were assessed at 1 and 3 months after surgery. In addition, postoperative complications were recorded. Patients were also compared based on the type of incision used during surgery (traditional longitudinal or “bikini” incision).ResultsPatients in the nerve block group showed significantly lower postoperative morphine consumption, lower resting VAS scores within 12 h postoperatively, lower VAS scores during motion within 24 h postoperatively, and better QoR‐15 scores on postoperative day 1. These patients also showed significantly better functional recovery during hospitalization. At 1‐month and 3‐month outpatient follow up, the two groups showed no significant differences in Oxford hip score or UCLA activity level rating. There were no significant differences in the incidence of postoperative complications. Similar results were observed when patients were stratified by type of incision, except that the duration of hospitalization was similar.ConclusionCompared to PIA alone, a combination of LFCNB and IHINB along with PIA can improve early pain relief, reduce morphine consumption, and accelerate functional recovery, without increasing complications after THA via the DAA.     

Ultrasound‐Assisted Precise In Situ Decompression for Cubital Tunnel Syndrome

ObjectiveTo explore the effect of locating the ulnar nerve compression sites and guiding the small incision so as to decompress the ulnar nerve in situ on the elbow by high‐frequency ultrasound before operation.MethodsA retrospective analysis was conducted on 56 patients who underwent ultrasound‐assisted in situ decompression for cubital tunnel syndrome from May 2018 to August 2019. The patients'' average age was 51.13 ± 7.35 years, mean duration of symptoms was 6.51 ± 1.96 months, and mean postoperative follow‐up was 6.07 ± 0.82 months. Nine patients had Dellon''s stage mild, 39 had stage moderate, and eight had stage severe. Ultrasound and electromyography were completed in all patients before operation. The presence of ulnar nerve compressive lesion, the specific location, and the reason and extent of compression were determined by ultrasound. A small incision in situ surgery was given to decompress the ulnar nerve according to the pre‐defined compressive sites.ResultsAll patients underwent in situ decompression. The compression sites around the elbow were as follows: two in the arcade of Struthers, one in the medial intermuscular septum, four in the anconeus epitrochlearis muscle, five beside the cyst of the proximal flexor carpi ulnaris (FCU), and the remaining 44 cases were all from the compression between Osborne''s ligament to the two heads of the FCU. The compression localizations diagnosed by ultrasound were confirmed by operations. Preoperative ultrasound confirmed no ulnar nerve subluxation in all cases. The postoperative outcomes were satisfactory. There was no recurrence or aggravation of symptoms in this group of patients according to the modified Bishop scoring system; results showed that 43 cases were excellent, 10 were good, and three were fair.ConclusionsHigh‐frequency ultrasound can accurately and comprehensively evaluate the ulnar nerve compression and the surrounding tissues, thus providing significant guidance for the precise minimally invasive treatment of ulnar nerve compression.

1990-2019年中国动脉粥样硬化心血管病疾病负担变化及其危险因素分析

目的 量化分析1990-2019年我国动脉粥样硬化心血管病（ASCVD）疾病负担及其主要危险因素影响的变化趋势。方法 利用2019年全球疾病负担（GBD2019）研究结果,以伤残调整寿命年（DALY）及其年龄标准化率为指标,分析1990-2019年我国ASCVD疾病负担和危险因素归因疾病负担的变化情况,并采用Gupta建立的分解法对人口增长、老龄化、年龄别患病率和疾病严重程度所致的DALY变化进行了量化分析。结果 2019年我国61.00%的心血管病疾病负担由ASCVD所致,缺血性心脏病的DALY较1990年增长了133.66%,其中29.57%可归因于人口增长、108.74%归因于人口老龄化、8.87%归因于年龄别患病率的增加、-13.53%归因于疾病严重程度;缺血性卒中的DALY较1990年增长了138.64%,归因于上述4部分的变化率依次为30.95%、123.38%、55.80%和-71.49%。2019年高血压依然是ASCVD首要危险因素,其次是高LDL-C,归因于饮酒的年龄标准化DALY率较1990年增幅最大（486.01%）,年均增长10.93%。结论 1990-2019年,人口老龄化是我国ASCVD疾病负担大幅增长最主要的原因,而其他可改变危险因素的不利趋势,特别是代谢性危险因素的持续流行同样不容忽视。
