Endoscopic ultrasound-guided biliary drainage vs percutaneous transhepatic bile duct drainage in the management of malignant obstructive jaundice

BACKGROUND Malignant obstructive jaundice(MOJ)is a condition characterized by varying degrees of bile duct stenosis and obstruction,accompanied by the progressive development of malignant tumors,leading to high morbidity and mortality rates.Currently,the two most commonly employed methods for its management are percutaneous transhepatic bile duct drainage(PTBD)and endoscopic ultrasound-guided biliary drainage(EUS-BD).While both methods have demonstrated favorable outcomes,additional research needs to be performed to determine their relative efficacy.To compare the therapeutic effectiveness of EUS-BD and PTBD in treating MOJ.METHODS This retrospective analysis,conducted between September 2015 and April 2023 at The Third Affiliated Hospital of Soochow University(The First People’s Hospital of Changzhou),involved 68 patients with MOJ.The patients were divided into two groups on the basis of surgical procedure received:EUS-BD subgroup(n=33)and PTBD subgroup(n=35).Variables such as general data,preoperative and postoperative indices,blood routine,liver function indices,myocardial function indices,operative success rate,clinical effectiveness,and complication rate were analyzed and compared between the subgroups.RESULTS In the EUS-BD subgroup,hospital stay duration,bile drainage volume,effective catheter time,and clinical effect-iveness rate were superior to those in the PTBD subgroup,although the differences were not statistically significant(P>0.05).The puncture time for the EUS-BD subgroup was shorter than that for the PTBD subgroup(P<0.05).Postoperative blood routine,liver function index,and myocardial function index in the EUS-BD subgroup were significantly lower than those in the PTBD subgroup(P<0.05).Additionally,the complication rate in the EUS-BD subgroup was lower than in the PTBD subgroup(P<0.05).CONCLUSION EUS-BD may reduce the number of punctures,improve liver and myocardial functions,alleviate traumatic stress,and decrease complication rates in MOJ treatment.

Percutaneous nephrostomy versus ureteral stent in hydronephrosis secondary to obstructive urolithiasis:A systematic review and meta-analysis

Objective: To assess if there is a preferable intervention between retrograde ureteral stent (RUS) and percutaneous nephrostomy (PCN) tube, in cases of upper urinary tract stone obstruction with complications requiring urgent drainage, by evaluating outcomes regarding urinary symptoms, quality of life (QoL), spontaneous stone passage, and length of hospital stays, since there is no literature stating the superiority of one modality over the other.Methods: We searched MEDLINE and other sources for relevant articles in June 2019 without any date restrictions or filters applied. The selection was done first by the title and abstract screening and then by full-text assessment for eligibility. Only randomized controlled trials or cohort studies in patients with hydronephrosis secondary to obstructive urolithiasis that presented comparative data between PCN and RUS placement concerning at least one of the defined outcome measures were included. Lastly, MEDLINE database and PubMed platform were screened again using the same terms, from June 2019 until November 2022.Results: Of 556 initial articles, seven were included in this review. Most works were considered of moderate-to-high quality. Three studies regarding QoL showed a tendency against stenting, even though only one demonstrated statistically significant negative impact on overall health state. Two works reported significantly more post-intervention urinary symptoms in stenting patients. One article found that PCN is a significant predictor of spontaneous stone passage, when adjusted for stone size and location. Findings on length of hospital stays were not consistent among articles.Conclusion: PCN appears to be the intervention better tolerated, with less impact on the patient’s perceived QoL and less post-operative urinary symptoms, in comparison with RUS. Nevertheless, further studies with larger samples and a randomized controlled design are suggested.

Ultrasound-guided fascia iliaca compartment block combined with general anesthesia for amputation in an acute myocardial infarction patient after percutaneous coronary intervention: A case report

BACKGROUND Fascia iliaca compartment block is a technique that blocks three nerves,similar to a 3-in-1 nerve block.This block provides analgesia for patients undergoing lower limb surgery,and is a simple technique that is easy to implement.Here,we report a case of fascia iliaca compartment block in a patient with myocardial infarction who underwent emergency middle thigh amputation.CASE SUMMARY A 78-year-old female patient weighing 38 kg with gangrene and occlusive peripheral atherosclerosis of the right leg underwent an emergency middle thigh amputation.The patient had a history of hypertension,coronary heart disease,cerebral infarction,anterior wall myocardial infarction,and had recently undergone percutaneous coronary intervention consisting of coronary angiography and right coronary artery stent implantation.Considering the patient's condition,an ultrasound-guided fascia iliaca compartment block combined with general anesthesia was implemented for amputation.The fascia iliaca compartment block provided analgesia for the operation,and reduced the dosage of general anesthetics.It also alleviated adverse cardiovascular effects caused by pain stress,and ensured the safety of the patient during the perioperative period.This block also provided postoperative analgesia.The patient had a good prognosis,and was subsequently discharged from hospital.CONCLUSION Fascia iliaca compartment block provides surgical analgesia.It also alleviates adverse cardiovascular effects,and ensures patient safety during the perioperative period.

Application of ultrasound-guided percutaneous radiofrequency ablation in treatment of liver cancer.

Objective To investigate the therapeutic efficacy and its influencing factors of ultrasoundguided percutaneous radiofrequency ablation (PRFA) in the treatment of liver carcinoma. Methods With a temperature-controlled multi-electrode needle, ultrasound-guided PRFA was employed to treat forty-seven patients with 67 tumor nodules, with a diameterof 2.6 ± 1.1 cm (1.0 - 5.5 cm). Results A complete ablation (CA) rate of 80. 6% was achieved in the present series, with a CA rate of 91.7 % in the tumors ≤3 cm in diameter,75. 0% in tumors from 3.1 to 4. 0 cm,and 14. 3% in tumors 】4 cm. The CA rate was significantly greater in tumors with a temperature rising up to 70℃ within the initial 2 minutes at ablation as compared with that longer than 2 minutes (P 【 0.05). A markedly higher CA rate was obtained in tumors with an ablation-maintaining temperature of over 80℃ than that between 70℃ and 80℃ ( P 【 0. 01). All patients were followed up with a mean time of 11. 3 months. The local recurrence rate was 9.3% (5/

Use of percutaneous nephrostomy and ureteral stenting in management of ureteral obstruction

The management options for ureteral obstruction are diverse, including retrograde ureteral stent insertion or antegrade nephrostomy placement, with or without eventual antegrade stent insertion. There is currently no consensus on the ideal treatment or treatment pathway for ureteral obstruction owing, in part, to the varied etiologies of obstruction and diversity of institutional practices. Additionally, different clinicians such as internists, urologists, oncologists and radiologists are often involved in the care of patients with ureteral obstruction and may have differing opinions concerning the best management strategy. The purpose of this manuscript was to review available literature that compares percutaneous nephrostomy placement vs ureteral stenting in the management of ureteral obstruction from both benign and malignant etiologies.

Clinical Application of Percutaneous Nephrostomy in Some Urologic Diseases

Percutaneous nephrostomy was applied in some other urologic diseases and the efficacy was evaluated. Percutaneous nephrostomy for percutaneous nephrolithotomy （PNL） was performed in patients with various renal, perinephric and bladder diseases （n=79）. The tract establishment, operation duration and complications were observed and the efficacy was assessed. The results showed that the tracts were successfully established in 79 cases. The operation lasted 4–20 min. 12F–16F single tract was established in nephrohydrop patients and 16F–20F single or multiple tracts were established in patients with pyonephrosis, renal cortical abscess, renal cyst and perinephric abscess. During dilation, no leakage of liquor puris was noted. Establishment of 18F single tract was achieved in one urinoma patient. In two patients with foreign body in kidney, the foreign bodies were removed via established 14F single tract. 18F tracts were established in 2 patients with bladder contracture, which was followed by the placement of 16F balloon urethral catheter for drainage. No complications, such as massive bleeding, intestinal injury and spreading of infection took place in our series. All the patients were followed up for 2–12 months. No long-term complications such as dropping of drainage tube occurred. It is concluded that as a minimally invasive technique, percutaneous nephrostomy has the advantages of convenience, simplicity and causing less complications and can be used for various urologic diseases.

Outcomes of Percutaneous Nephrolithotomy with or without Nephrostomy Tube: A Comparative Study

Objectives: To compare the outcomes of Percutaneous Nephrolithotomy (PCNL) with or without nephrostomy tube. Materials & Methods: This prospective comparative study intended to compare the outcomes between PCNL without nephrostomy tube and PCNL with nephrostomy tube. A total of 50 cases of renal stone disease planned for PCNL in Dhaka Medical College Hospital from July 2015 to June 2017, were included in this study according to the statistical calculation. Cases were randomly allocated to group A (PCNL without nephrostomy tube) and group B (PCNL with nephrostomy tube). Each group consisted of 25 patients. The outcome variables were post operative pain, requirement of analgesic, leakage of urine and post operative hospital stay. Data were analyzed and compared by statistical tests. Results: No significant differences were found regarding age (p = 0.95), sex (p = 0.55) and operation time (p = 0.36) between two groups. Post operative pain (p p p p Conclusions: Percutaneous nephrolithotomy without nephrostomy tube is better than percutaneous nephrolithotomy with nephrostomy tube in selective cases. It significantly reduces post operativepain, analgesic requirement and postoperative hospital stay. So percutaneous nephrolithotomy without nephrostomy tube is safe and effective.

Comparative clinical study of ultrasound-guided A1 pulley release vs open surgical intervention in the treatment of trigger finger

AIM To investigate the effectiveness of ultrasound-guided release of the first annular pulley and compare results with the conventional open operative technique.METHODS In this prospective randomized, single-center, clinical study, 32 patients with trigger finger or trigger thumb, grade Ⅱ-Ⅳ according to Green classification system, were recruited. Two groups were formed; Group A(16 patients) was treated with an ultrasound-guided percutaneous release of the affected A1 pulley under local anesthesia. Group B(16 patients) underwent an open surgical release of the A1 pul ey, through a 10-15 mm incision. Patients were assessed pre- and postoperatively(follow-up:2,4 and 12 wk) by physicians blinded to the procedures. Treatment of triggering(primary variable of interest) was expressed as the "success rate" per digit. The time for taking postoperative pain killers, range of motion recovery, QuickD ASH test scores(Greek version), return to normal activities(including work), complications and cosmetic results were assessed.RESULTS The success rate in group A was 93.75%(15/16) and in group B 100%(16/16). Mean times in group A patients were 3.5 d for taking pain killers, 4.1 d for returning to normal activities, and 7.2 and 3.9 d for complete extension and flexion recovery, respectively. Mean Quick DASH scores in group A were 45.5 preoperatively and, 7.5, 0.5 and 0 after 2, 4, and 12 wk postoperatively. Mean times in group B patients were 2.9 d for taking pain killers, 17.8 d for returning to normal activities, and 5.6 and 3 d for complete extension and flexion recovery. Mean QuickD ASH scores in group B were 43.2 preoperatively and, 8.2, 1.3 and 0 after 2, 4, and 12 wk postoperatively. The cosmetic results found excellent or good in 87.5%(14/16) of group A patients, while in 56.25%(9/16) of group B patients were evaluated as fair or poor.CONCLUSION Treatment of the trigger finger using ultrasonography resulted in fewer absence of work days, and better cosmetic results, in comparison with the open surgery technique. It is a promising method that represents excellent results without major complications, so that it could be possibly be established as a first-line treatment in the trigger finger's disease.

Appropriate kidney stone size for ureteroscopic lithotripsy:When to switch to a percutaneous approach

Flexible ureteroscopy(f URS) has become a more effective and safer treatment for whole upper urinary tract stones. Percutaneous nephrolithotomy(PNL) is currently the first-line recommended treatment for large kidney stones ≥ 20 mm and it has an excellent stone-free rate for large kidney stones. However, its invasiveness is not negligible considering its major complication rates. Staged f URS is a practical treatmentfor such large kidney stones because f URS has a minimal blood transfusion risk, short hospitalization and few restrictions on daily routines. However, as the stone size becomes larger, the stone-free rate decreases, and the number of operations required increases. Therefore, in our opinion, staged f URS is a practical option for kidney stones 20 to 40 mm. Miniaturized PNL combined with f URS should be considered to be a preferred option for stones larger than 40 mm. Moreover, URS is an effective treatment for multiple upper urinary tract stones. Especially for patients with a stone burden < 20 mm, URS is a favorable option that promises a high stone-free rate after a single session either unilaterally or bilaterally. However, for patients with a stone burden ≥ 20 mm, a staged operation should be considered to achieve stone-free status.

Ultrasound-guided vs endoscopic ultrasound-guided fine-needle aspiration for pancreatic cancer diagnosis

AIM: To clarify the effectiveness and safety of endo- scopic ultrasound-guided fine-needle aspiration (EUS-FNA) for the diagnosis of pancreatic cancer (PC). METHODS: Patients who were diagnosed with unresectable, locally advanced or metastatic PC between February 2006 and September 2011 were selected for this retrospective study. FNA biopsy for pancreatic tumors had been performed percutaneously under extracorporeal ultrasound guidance until October 2009; then, beginning in November 2009, EUS-FNA has been performed. We reviewed the complete medical records of all patients who met the selection criteria for the following data: sex, age, location and size of the targeted tumor, histological and/or cytological findings, details of puncture procedures, time from day of puncture until day of definitive diagnosis, and details of severe adverse events. RESULTS: Of the 121 patients who met the selection criteria, 46 had a percutaneous biopsy (Group A) and 75 had an EUS-FNA biopsy (Group B). Adequate cytological specimens were obtained in 42 Group A patients (91.3%) and all 75 Group B patients (P=0.0192), and histological specimens were obtained in 41 Group A patients (89.1%) and 65 Group B patients (86.7%). Diagnosis of malignancy by cytology was positive in 33 Group A patients (78.6%) and 72 Group B patients (94.6%) (P=0.0079). Malignancy by both cytology and pathology was found in 43 Group A (93.5%) and 73 Group B (97.3%) patients. The mean period from the puncture until the cytological diagnosis in Group B was 1.7 d, which was significantly shorter than that in Group A (4.1 d) (P < 0.0001). Severe adverse events were experienced in two Group A patients (4.3%) and in one Group B patient (1.3%). CONCLUSION: EUS-FNA, as well as percutaneous needle aspiration, is an effective modality to obtain cytopathological confirmation in patients with advanced PC.

Laparoscopic ureterolysis with simultaneous ureteroscopy and percutaneous nephroscopy for treating complex ureteral obstruction after failed endoscopic intervention:A technical report

Objective:Complex ureteral obstruction is refractory to conventional urological intervention.This report describes a case of laparoscopic ureterolysis with simultaneous ureteroscopy and percutaneous nephroscopy for treating complex ureteral obstruction.Methods:Right-side multiple ureteral stones and complicating ureteral obstruction failed an initial attempt of ureteroscopy lithotripsy with simultaneous percutaneous nephroscopy in a 23-year-old male.Laparoscopic ureterolysis with ureteroscopy and percutaneous nephroscopy was used simultaneously to dissect the periureteral adhesions with the patient placed in the Galdakao-modified supine Valdivia position.The ureter was incised to allow the insertion of a ureteral catheter through the twisted ureter,and a guide wire was advanced into the pelvis using ureteroscopy.A double-J stent was placed into the right-side ureter using antegrade percutaneous nephroscopy.Results:The laparoendoscopic procedure lasted 330 min with an estimated bleeding volume of 100 mL.The patient underwent an uneventful postoperative course,and postoperative followup radiography confirmed good positioning of the double-J stent.The double-J stent was removed 3 months after operation.The patient remained asymptomatic within a 13-month follow-up period.Conclusion:Laparoscopic ureterolysis with simultaneous ureteroscopy and percutaneous nephroscopy is an effective and safe treatment option for complex ureteral obstruction.

Interventional Ultrasound in Ambulatory Urological Practice: Experience of the Medicis Clinic in Conakry

Introduction: Minimally invasive urological interventions have long been practiced blindly in our context. The popularization of ultrasound in urological practice has contributed to changing habits by making the procedures safer and more effective. The objective of this work was to study the technical aspects, indications and results of minimally invasive urological procedures guided by ultrasound. Material and methods: This was a prospective descriptive study lasting 1 year from January to December 2023 at the Médicis clinic in Conakry. Results: We carried out 126 ultrasound-guided urological interventions in one year, including 6 percutaneous nephrostomies (NPC), one renal cyst puncture-aspiration-sclerotherapy, 102 prostate biopsies, 5 drainages by transrectal aspiration of prostatic abscesses, 10 placements of cystostomy probes. Suprapubic, 2 puncture-aspiration-sclerotherapies for vaginal hydroceles. The average age of our patients was 69 years and the predominant age range was 61 - 70. The majority of our patients were male (97.61%) with a sex ratio of 41 men to one woman. Ultrasound-guided urological interventions were for diagnostic purposes (80.95%), for therapeutic purposes (15.77%) and for diagnostic and therapeutic purposes (3.96%). The indications for ultrasound-guided urological interventions were dominated by prostate pathologies (84.91%). The majority of interventions were performed rectally (84.92%) versus (13.43%) abdominally and only 1.58% scrotalally. All procedures were performed in B-ultrasound mode under local anesthesia and on an outpatient basis. For therapeutic interventions, the patients were seen again one month after the procedure, the clinical examination and ultrasound control found the evolution to be favorable. Conclusion: ultrasound is useful in urological practice for guiding minimally invasive interventions. The indications for ultrasound-guided procedures in urology are dominated by prostate pathologies. These procedures are safe and effective with fewer complications. Interventional ultrasound must be further integrated into the habits of urologists.

外引流方式在输尿管结石合并尿脓毒血症治疗中的应用效果

目的:分析外引流方式在输尿管结石合并尿脓毒血症治疗中的应用效果。方法:选取2020年10月—2022年5月钦州市第一人民医院收治的输尿管结石合并尿脓毒血症患者64例作为研究对象,随机分为两组,各32例。对照组行输尿管镜双J管置入术,观察组行超声引导下经皮肾穿刺造瘘术。比较两组治疗效果。结果:观察组尿毒症控制时间、住院时间短于对照组,差异有统计学意义(P<0.05);两组引流成功率比较,差异无统计学意义(P>0.05)。术前,两组降钙素原(PCT)、C反应蛋白(CRP)、嗜中性粒细胞(NEUR)、白细胞(WBC)水平比较,差异无统计学意义(P>0.05);术后2 d,两组PCT、CRP、NEUR、WBC水平低于术前,且观察组低于对照组,差异有统计学意义(P<0.05)。观察组并发症总发生率低于对照组,差异有统计学意义(P=0.021)。结论:对于输尿管结石合并尿脓毒血症患者,内、外引流方式的引流成功率均较高,但外引流方式能够更好地控制感染情况,减少并发症,促进患者恢复。

超声引导下经皮肾穿刺微造瘘在腹腔镜肾切除术治疗巨大肾积水中的应用

目的:探讨超声引导下经皮肾穿刺微造瘘在腹腔镜肾切除术治疗巨大肾积水中的应用效果。方法:回顾性分析因巨大肾积水行腹腔镜肾切除术的49例患者资料,男27例,女22例;左肾26例,右肾23例。所有患者术前均行泌尿系超声、静脉尿路造影、泌尿系CT等检查明确诊断为巨大肾积水。术前均应用一次性中心静脉导管在超声引导下行经皮肾穿刺微造瘘术,术前行引流液相关检测。49例均判断为患肾无功能或患肾为脓肾而行腹腔镜肾切除术。手术方式包括经阴道自然腔道内镜手术肾切除术、耻骨上辅助单孔腹腔镜肾切除术和后腹腔镜肾切除术,记录手术时间、术中失血量、术后24 h视觉模拟疼痛评分、下床活动时间、拔除引流管时间、切口拆线时间、术后住院时间等。结果:49例均顺利完成超声引导下经皮肾穿刺微造瘘术,引流1周后,中位肾小球滤过率为9.42(7.03~18.77) mL·min^(-1),中位引流液pH值7.3(6.5~8.5),中位引流液比重1.012(1.003~1.034),中位肾实质厚度为5(2~10) mm,均未发生穿刺通道出血、肾脏出血及其他副损伤等穿刺相关并发症。所有腹腔镜肾切除术均顺利完成,无中转开放手术,无增加工作通道。中位手术时间120(75~138) min,术中中位估计失血量90(60~210) mL。均未输血,术中无副损伤,术后24 h中位视觉模拟疼痛评分2(1~3)分,术后第1 d下床活动,术后第3~4 d拔除引流管,术后第7~8 d切口拆线,中位术后住院时间5(4~8) d。患者术后恢复顺利,切口愈合良好,术后复查肾功能与术前无显著变化。所有标本病理检查与术前诊断相符合。所有患者术后均获随访,中位随访时间9(8~12)月,均恢复良好。结论:巨大肾积水患者于腹腔镜肾切除术前行超声引导下经皮肾穿刺微造瘘术,能够客观、准确地评价患肾功能,减少手术并发症,降低手术难度,缩短手术时间。
