ABSTRACT
AIM:To observe the accuracy of infiltrating B ultrasound guided A-scan segment biometric measurement of axial length in dense cataract.METHODS: Perspective study. A total of 86 patients(90 eyes)with dense cataract were selected from Chengdu Aier Eye Hospital from August 2020 to August 2022. There were 61 males(59 eyes)males and 25 females(31 eyes)females, with an average age of 66.49±14.55 years. The axial length(AL), anterior chamber depth(ACD)(including corneal thickness), corneal curvature(K), lens thickness(LT), central corneal thickness(CCT), and white-to-white(WTW)were measured preoperatively by contact A-scan, infiltrating B ultrasound guided segmented A-scan, and IOL Master 700, respectively. At 1 wk postoperatively, AL was retested by IOL Master 700 in aphakic mode. Furthermore, the agreements and correlations of AL obtained by the three kinds of devices were analyzed.RESULTS:The AL measured by contact A-scan and infiltrating B ultrasound guided segmented A-scan were 23.40(22.63, 23.89)mm and 23.70(23.04, 24.25)mm, respectively, and the AL measured by IOL Master 700 at 1 wk postoperatively was 23.72(23.01, 24.27)mm. There were statistical significant difference in AL measured by the three methods(P=0.018), while there were no statistical significant difference in AL measured by infiltrating B ultrasound guided segmented A-scan and IOL Master 700(P=0.991). Bland-Altman analysis showed that there was a good agreement in AL measured by infiltrating B ultrasound guided segmented A-scan and IOL Master 700(P=0.0809). The AL measured by infiltrating B ultrasound guided segmented A-scan and IOL Master 700 was positively correlated(rs=0.992, P<0.0001), and the AL was positively correlated between preoperative contact A-scan and postoperative IOL Master 700(rs=0.989, P<0.0001).CONCLUSION:For dense cataract, infiltrating B ultrasound guided A-scan segment biometric measurement, which has good correlations and agreement, is closer to the AL measured by IOL Master 700 postoperatively than that measured by contact A-scan.
ABSTRACT
Objective:To evaluate the diagnostic value of rapid on-site evaluation (ROSE) performed by endoscopists for solid pancreatic lesions requiring tissue for immunohistochemistry (IHC) staining with different approach of endoscopic ultrasound-guided tissue acquisition (EUS-TA).Methods:After screening 1 573 cases who underwent EUS-TA operation at the Endoscopy Center of Peking Union Medical College Hospital between August 2018 and October 2022, a total of 65 cases of solid pancreatic lesions whose diagnosis rely on IHC staining was collected and summarized with clinical data of each case. Among 65 cases, there were 46 cases of pancreatic neuroendocrine tumors (PNETs), 13 cases of pancreatic solid pseudo-papillary tumors (SPTs), and 6 cases of lymphomas and mesenchymal. Patients were categorized into ROSE group (36 cases) and non-ROSE group (29 cases) according to the presence or absence of endoscopists performed ROSE during EUS-TA operation. They were further divided into subgroups of FNA-ROSE (26 cases), FNB-ROSE (10 cases), FNA-non-ROSE (24 cases) and FNB-non-ROSE (5 cases) according to the type of EUS-TA. Diagnostic accuracy and IHC success rate were compared between different groups and subgroups. Binomial logistic multifactorial regression analysis was used to evaluate the influence of ROSE and EUS-TA type on diagnostic accuracy and IHC success rate.Results:There were no statistically significant differences between ROSE group and non-ROSE group in terms of age, gender, bilirubin level, CA19-9 level, lesion site, lesion size, composition ratio of diagnosis, and surgical rate. The differences in mean size of lesions, needle gauge, location of puncturation, and number of needle pass between subgroups were not statistically significant. The diagnostic accuracy was 88.9% in ROSE group and 79.3% in non-ROSE group, and the difference between the two groups was statistically significant ( P=0.023). The diagnostic accuracy of FNA-ROSE group was higher than that of FNA-non-ROSE group (88.5% vs 75.0%), but the difference was not statistically significant ( P>0.100). The differences in diagnostic accuracy and success rate of IHC between FNB-ROSE group and FNB-non-ROSE group were not statistically significant. Binomial logistic multifactorial regression analysis did not reveal any independent influences on diagnostic accuracy. Conclusions:ROSE performed by endoscopists improved diagnostic accuracy of EUS-TA in solid pancreatic lesions requiring IHC staining, and therefore is potentially valuable for improving the diagnostic efficiency of EUS-TA for such diseases.
ABSTRACT
Objective:To analyze clinical characteristics of primary pancreatic lymphoma (PPL) patients.Methods:Clinical features of 22 patients diagnosed as PPL admitted to Peking Union Medical College Hospital from January 2002 to May 2023 were analyzed retrospectively.Results:The median age was 56.4±13.3 years. The median time from onset to diagnosis was 1.0 (1.0, 3.0) months. The main clinical manifestations were abdominal pain (15/22), weight loss (14/22) and jaundice (10/22). Elevated lactate dehydrogenase (LDH) was observed in 15/20 (75%) patients. Only 2 (2/9, 22.2%) patients had increased CA199 levels and 2 (2/9, 22.2%) patients had increased CEA levels. The maximum tumor diameter was 5.0 (3.8, 6.9) cm. Contrast-enhanced CT mostly showed low enhancement lesions. Major pancreatic duct dilatation were rare on CT scan (4/20). Fifteen patients were confirmed by pancreatic pathology, of which 8 were obtained by surgery, 4 were obtained by CT or ultrasound-guided percutaneous biopsy, and 3 were obtained by EUS-FNA. The main pathological type was diffuse large B-cell lymphoma (14/22). 19 patients received chemotherapy, and 6 patients died with a median follow-up of 5.0 (1.5, 35.5) months.Conclusions:PPL is rare and easy to be misdiagnosed. Elevated LDH levels, normal tumor markers, and non-dilatation of main pancreatic duct are important diagnostic clues. It is important to obtain pathology by EUS-FNA and other methods for definite diagnosis.
ABSTRACT
Objective To compare the short-term efficacy and safety of low temperature plasma radiofre-quence ablation(LA)vs.high voltage long duration pulsed radiofrequency(HL-PRF)in the treatment of cervico-genic headache(CEH).Methods Eighty patients with cervicogenic headache were divided two groups:one treated with low temperature plasma radiofrequence ablation group as group L(n = 50)and the other treated with high voltage long duration pulsed radiofrequency group as group H(n = 30).The two groups were compared in terms of the score by the Visual Analog Scale,score by the Range of Motion Scale,postoperative pain relief rate,postop-erative complication incidence,1,4,12,and 24 weeks after the operation,as well as the therapeutic effectiveness and safety.Results Both groups showed significantly lower VAS and ROM scores after operation(P<0.05).Compared with group L,group H had significantly lower VAS(all P<0.05)but insignificantly lower ROM scores(all P>0.05)at each time point.At T4,group H had significantly higher therapeutic effectiveness rate(P<0.05)and higher incidence of scalp numbness at T3,as compared to group L(P<0.05).Conclusion The low tempera-ture plasma radiofrequency ablation and high voltage long duration pulsed radiofrequency both are effective and safe in the treatment of CEH,the latter approach can achieve better therapeutic effectiveness 24 weeks after the operation than the former.

ABSTRACT
Objective:To investigate the application of endoscopic ultrasound-guided liver biopsy (EUS-LB) to liver transplant recipients.Methods:In this retrospective cohort study, a total of 12 liver transplant recipients who underwent EUS-LB by the same endoscopist and specimens were diagnosed and reported by the same pathologist due to abnormal liver function or need to be evaluated for graft fibrosis in the Organ Transplantation Center of the Affiliated Hospital of Qingdao University were enrolled into the EUS-LB group from December 2021 to March 2022, meanwhile, a total of 23 patients whose PLB was completed by the same hepatologist and specimens were diagnosed by the same pathologist during the same period were enrolled in the PLB group. Acquisition of liver specimens and postoperative adverse events of the two groups were compared.Results:Patients in both groups were punctured 1-2 times on average, and the median total length of liver specimens in the EUS-LB group was significantly longer than that in the PLB group (61 mm VS 17 mm, Z=11.362, P=0.002). There was no significant difference in the length of the longest liver specimens between the two groups (17.6±6.9 mm VS 13.7±3.5 mm, t=2.382, P=0.086), while the number of liver specimens in the EUS-LB group was more than that in the PLB group (4.8±2.1 VS 2.3±1.2, t=9.271, P=0.001). The number of complete portal tracts was 11.3±4.6 in the EUS-LB group and 6.2±3.3 in the PLB group ( t=8.457, P=0.003). Abdominal pain was the only postoperative adverse event, and only 1 patient in the EUS-LB group had postoperative abdominal pain, which was fewer than that in the PLB group [8.3% (1/12) VS 43.5% (10/23), χ2=4.893, P=0.036]. Conclusion:Compared with PLB, EUS-LB delivers longer liver biopsy specimens with more complete portal tracts in liver transplant recipients, and fewer recipients complain about postoperative pain in EUS-LB group. Therefore, EUS-LB is a safer, more effective and more comfortable liver biopsy method.
ABSTRACT
ObjectiveTo summarize the liver biopsy and clinical features of patients with liver injury of unknown origin， and to investigate the value of ultrasound-guided percutaneous liver biopsy in the diagnosis of liver injury of unknown origin. MethodsA retrospective analysis was performed for the clinical data and ultrasound-guided percutaneous liver biopsy results of 94 patients with liver injury of unknown origin who were admitted to Zhongshan Hospital， Xiamen University， from January 2018 to February 2023. According to the proportion of the patients with different final diagnoses， the patients were divided into autoimmune liver disease （AILD） group， metabolic associated fatty liver disease （MAFLD） group， drug-induced liver injury （DILI） group， alcoholic liver disease （ALD） group， and unknown group. An analysis of variance was used for comparison of normally distributed continuous data between multiple groups， and the Bonferroni analysis or the Dunnett’ T3 test was used for further comparison between two groups； the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups； the Fisher’s exact test was used for comparison of categorical data between multiple groups. ResultsAll 94 patients with liver injury of unknown origin underwent ultrasound-guided percutaneous liver biopsy after admission， among whom 90 patients （95.7%） had a confirmed diagnosis based on liver biopsy and clinical features. There were 43 patients （45.7%） with AILD， 21 （22.3%） with MAFLD， 15 （16.0%） with DILI， 6 （6.4%） with ALD， 1 （1.1%） with AILD and MAFLD， 1 （1.1%） with hemochromatosis， 1 （1.1%） with Budd-Chiari syndrome， 1 （1.1%） with congenital hepatic fibrosis， and 1 （1.1%） with idiopathic portal hypertension， while 4 patients （4.3%） still had an unknown etiology after liver biopsy. There were significant differences between the patients with top five diagnoses in age （F=4.457， P<0.05） ， body mass index （BMI） （F=3.245， P<0.05）， aspartate aminotransferase （AST） （H=11.128， P<0.05）， gamma-glutamyl transpeptidase （GGT） （H=24.789， P<0.05）， alkaline phosphatase （ALP） （H=26.013， P<0.05）， IgG （H=19.099， P<0.05）， IgM （H=21.263， P<0.05）， AMA-M2 positive rate （P<0.05）， and ANA positive rate （P<0.05）. Compared with the MAFLD group， the AILD group had significantly higher age， AST， GGT， and ALP and a significantly lower BMI； compared with the MAFLD group and the DILI group， the AILD group had significant increases in IgG and IgM； the AILD group had significant increases in the positive rates of AMA-M2 and ANA compared with the other four groups. ConclusionAILD， MAFLD， and DILI are the most common causes in patients with liver injury of unknown origin. Ultrasound-guided percutaneous liver biopsy plays an important role in determining the cause of liver injury of unknown origin， but it is still needed to make a comprehensive analysis based on clinical history， different types of liver injury， laboratory markers， and imaging data.
ABSTRACT
Objective: We report a case of spontaneous migration of a dedicated plastic stent after endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) in a patient with surgically altered anatomy.Patient: The patient was a male in his 70s. He underwent EUS-HGS with the successful insertion of a dedicated plastic stent and had no obvious postprocedural complications. However, nine days after the procedure, the patient visited our hospital because of abdominal pain, fever, and stent excretion. We performed EUS-HGS with antegrade stenting, after which the patient had no further complications.Conclusion: Stent migration is considered a complication requiring caution when performing EUS-HGS in patients with surgically altered anatomy.
ABSTRACT
Introduction: Intrathoracic lymph node metastasis from extrathoracic neoplasms are rare. Primary malignancies that metastasize to mediastinal-hilar lymph nodes are head and neck , carcinoma breast ,and genitourinary. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA)/endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is currently the preferred modality for mediastinal lymph node sampling. Methods: Fifty seven patients with extrathoracic malignancies with maximum standardized uptake value (SUVmax) of mediastinal-hilar lymph nodes greater than or equal to 2.5 were taken up for EBUS-TBNA. The histo-cytopathological results obtained from EBUS-TBNA were compared with SUVmax value and short-axis diameter of a lymph node as noted on EBUS. Results: Out of 74 sampled nodes, 49 (66.2%) were benign and 25 (33.8%) were malignant. The SUVmax range of benign nodes was 2.8� as compared to 3� of malignant nodes. The size range of malignant and benign nodes were 8� mm and 8� mm, respectively. The mean size of abnormal nodes (metastatic + granulomatous) was 17.5 (8� mm) and the mean SUVmax was 9.1 (3.4�), and it was a statistically significant difference when compared to reactive (normal) nodes. At SUVmax cut-off 7.5, sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) were 78.5%, 81.2%, 84.6%, and 74.2%, respectively for detecting abnormal nodes. At 13 mm size cut-off, sensitivity, specificity, PPV, NPV were 75.5%, 65%, 75%, and 72%, respectively, for detecting abnormal nodes. Conclusion: The majority of mediastinal-hilar nodes with increased metabolic activity are benign in nature. Size and SUVmax are poor predictors of metastasis in tuberculosis endemic region. There should be a restrictive attitude toward invasive diagnostic testing for mediastinal-hilar nodes in extrathoracic malignancies.

Objective:To investigate the efficacy of tibial nerve block achieved through different approaches combined with patient-controlled intravenous analgesia for surgical treatment of calcaneus fractures.Methods:This is a case-control study. A total of 80 patients scheduled for calcaneus surgeries at Guangxi Orthopedic Hospital from January to December 2022 were randomly assigned to undergo either a tibial nerve combined with medial sural nerve block on the upper leg (T1 group, n = 40) or a tibial nerve block on the popliteal fossa (T2 group, n = 40). All nerve blocks were performed under ultrasound guidance. Following surgery, the same medication was used to set up the intravenous infusion pump. At 6, 12, 24, and 48 hours post-surgery, the Visual Analogue Scale scores were recorded. At 1 and 2 days post-surgery, the Pittsburgh Sleep Quality Index scores and the duration of postoperative sensory and motor nerve blocks were documented. The need for postoperative pain relief medication and the occurrence of nausea and vomiting were also recorded. Patient satisfaction with postoperative analgesia was assessed. Results:There was no significant difference in Visual Analogue Scale scores between the two groups at different time points after surgery (all P > 0.05), and there was no significant difference in Pittsburgh Sleep Quality Index scores between the two groups after surgery ( P > 0.05). The duration of postoperative sensory and motor nerve block in the T1 group were (20.98 ± 2.06) hours and (18.88 ± 2.31) hours, respectively, which were significantly shorter than (22.75 ± 1.71) hours and (20.78 ± 1.95) hours in the T2 group ( t = -4.20, -3.97, both P < 0.001). There was no significant difference in patient satisfaction with postoperative analgesia between the two groups ( P > 0.05). Conclusion:Two different approaches of tibial nerve block combined with an intravenous analgesia pump can provide satisfactory analgesic effects after surgical treatment of calcaneus fractures. Ultrasound-guided tibial nerve block combined with medial sural nerve block can more quickly restore postoperative limb motor function than tibial nerve block on the popliteal fossa.
ABSTRACT
Objective To investigate the influencing factors and establish a model predicting the performance of needle visualization in fine-needle aspiration (FNA) of thyroid nodules. Methods This study prospectively included 175 patients who underwent FNA of thyroid nodules in the Department of Ultrasound in China-Japan Friendship Hospital and compared the display of the needle tips in the examination of 199 thyroid nodules before and after the application of needle visualization.We recorded the location,the positional relationship with thyroid capsule,ultrasonic characteristics,and the distribution of the soft tissue strip structure at the puncture site of the nodules with unclear needle tips display before using needle visualization.Furthermore,according to the thyroid imaging reporting and data system proposed by the American College of Radiology,we graded the risk of the nodules.Lasso-Logistic regression was employed to screen out the factors influencing the performance of needle visualization and establish a nomogram for prediction. Results The needle tips were not clearly displayed in the examination of 135 (67.8%) and 53 (26.6%) nodules before and after the application of needle visualization,respectively,which showed a significant difference (P<0.001).Based on the positional relationship between the nodule and capsule,anteroposterior/transverse diameter (A/T) ratio,blood supply,and the distribution of subcutaneous strip structure at the puncture site,a nomogram was established to predict the probability of unclear display of the needle tips after application of needle visualization.The C-index of the prediction model was 0.75 (95%CI=0.67-0.84) and the area under the receiver operating characteristic curve was 0.72.The calibration curve confirmed the appreciable reliability of the prediction model,with the C-index of 0.70 in internal validation. Conclusions Needle visualization can improve the display of the needle tip in ultrasound-guided FNA of thyroid nodules.The nomogram established based on ultrasound features such as the positional relationship between the nodule and capsule,A/T ratio,blood supply,and the distribution of subcutaneous strip structure at the puncture site can predict whether needle visualization is suitable for the examination of nodules.

ABSTRACT
Objective:To investigate the therapeutic effects of B ultrasound-guided extracorporeal shock wave lithotripsy combined with tamsulosin hydrochloride medication on ureteral calculi.Methods:The clinical data of 130 patients with ureteral calculi who received treatment in Ninghai First Hospital from March 2019 to June 2020 were retrospectively analyzed. These patients were divided into an observation group and a control group ( n = 65/group) according to the different treatment methods. Patients in the control group received B ultrasound-guided extracorporeal shock wave lithotripsy, and those in the observation group received B ultrasound-guided extracorporeal shock wave lithotripsy combined with tamsulosin hydrochloride medication. Total response rate, stone-free rate after the first treatment, time taken to get rid of stone, treatment times, and Visual Analogue Scale (VAS) score 14 days after the first treatment were compared between the two groups. Renal function indexes (serum creatinine, blood urea nitrogen), mean arterial pressure, VAS score, blood loss, and immunoglobulin G, immunoglobulin M, malondialdehyde, superoxide dismutase levels were determined in the two groups. Results:The total response rate in the control group was significantly lower than that in the observation group [89.23% (58/65) vs. 98.46% (64/65), χ2 = 4.80, P < 0.05]. After 14 days of treatment, the VAS score in the observation group was significantly lower than that in the control group [(3.97 ± 0.36) points vs. (5.59 ± 0.87) points, t = 13.87, P < 0.05).

The time taken to get rid of stone and treatment times in the control group were (18.98 ± 3.52) days and (2.53 ± 0.50) times, respectively, which were significantly higher than (12.27 ± 2.77) days and (1.64 ± 0.55) times in the observation group ( t = 12.08, 9.66, both P < 0.05). Urine Kim-1 in the observation group was significantly higher than that in the control group [(89.46 ± 42.46) mmol/L vs. (72.75 ± 17.65) mmol/L, t = 2.93, P < 0.05]. Serum creatinine and blood urea nitrogen levels in the observation group were (101.75 ± 24.53) μmol/L and (348.76 ± 29.84) μmol/L, respectively, which were significantly lower than (139.53 ± 30.56) μmol/L and (397.65 ± 35.64) μmol/L in the control group ( t = 5.82, 8.48, both P < 0.05). After 20-minutes of anesthesia induction, the mean arterial pressure in the observation group was significantly higher than that in the control group [(83.45 ± 12.65) mmHg (1 mmHg=0.133 kPa) vs . (61.68 ± 9.75) mmHg, t = -10.99, P < 0.05].

The combined therapy can effectively reduce pain, increases the treatment efficacy, and is worthy of reference and promotion in clinical practice.
ABSTRACT
Objective:To investigate the clinical efficacy of ultrasound-guided closed reduction and percutaneous Kirschner wire fixation in the treatment of supracondylar fractures of the humerus in children.Methods:The clinical data of 78 children with Gartland type II and type III straight-type supracondylar fractures of the humerus who received treatment in The First Affiliated Hospital of Anhui Medical University from October 2019 to October 2022 were retrospectively analyzed. These children were divided into an observation group ( n = 38) and a control group ( n = 40) according to different treatment methods. The observation group was subjected to ultrasound-guided closed reduction and percutaneous Kirschner wire fixation. The control group was given C-arm fluoroscopy-guided closed reduction and percutaneous Kirschner wire fixation. Mayo elbow performance score (MEPS), clinical healing time, operative time, and the incidence of intraoperative complications such as vascular and nerve injury were compared between the two groups. Results:Both groups of children achieved closed reduction without open reduction. The operative time in the observation group was (30.68 ± 5.45) minutes, which was significantly shorter than (40.54 ± 5.78) minutes in the control group ( t = 2.30, P < 0.05). The healing time of the fracture in the observation and control groups was (32.73 ± 4.56) days and (36.47 ± 6.24) days, respectively, and there was no significant difference between the two groups ( P > 0.05). The range of joint motion and elbow hyperextension angle range in the observation group were (148.78 ± 3.81)° and (8.72 ± 8.92)°, respectively, and they were (147.24 ± 4.36)° and (7.98 ± 8.86)°, respectively in the control group. There were no significant differences in the range of joint motion and elbow hyperextension angle range between the two groups (both P > 0.05). The excellent and good rate of joint function in the control and observation groups was 92.5% (37/40) and 92.1% (35/38), respectively. There was no significant difference in excellent and good rate of joint function between the two groups ( P > 0.05). There were three cases of postoperative nerve damage in the control group and no vascular or nerve damage was observed in the observation group. There were significant differences in the number of cases of vascular or nerve injury between the two groups ( χ2 = 3.97, both P < 0.05). Conclusion:Ultrasound-guided closed reduction and percutaneous Kirschner wire fixation for the treatment of supracondylar fractures of the humerus can shorten the operative time, decrease the incidence of intraoperative nerve injury, and reduce the X-ray exposure time of doctors and patients.
ABSTRACT
Objective:To explore the feasibility of smart phone real-time picture exchange-assisted telecytopathology for rapid on-site evaluation (tele-ROSE), and the role of tele-ROSE in improving the diagnostic efficiency of endoscopic physicians.Methods:Data of patients who underwent endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) from April 2020 to May 2021 in Qilu Hospital of Shandong University were retrospectively collected. Patients who didn't receive ROSE from April 2020 to October 2020 were enrolled in the non-ROSE group, and those who underwent ROSE from November 2020 to May 2021 were enrolled in the ROSE group, of which endosonographers used WeChat on the smartphone to send ROSE images to cytopathologists from November 2020 to March 2021 were the mobile phone group, and those whose ROSE results independently diagnosed by trained endosonographers from April 2021 to May 2021 were the self-ROSE group. Basic information, ROSE results, postoperative pathology and follow-up were compared, and the diagnostic effectiveness of tele-ROSE was analyzed.Results:A total of 188 cases were included, of which 179 cases (95.2%) were solid pancreatic lesions and 9 (4.8%) were enterocoelia lesions. There was no significant difference in the puncture time among the non-ROSE, mobile phone and self-ROSE groups [3 (3, 4) VS 3 (3, 4) VS 3 (2, 4), H=1.320, P=0.517]. With the final diagnosis as the golden standard, the sensitivity, the specificity, the accuracy, the positive predictive value, the negative predictive value and Kappa value of the non-ROSE group were 80.6% (58/72), 89.5% (17/19), 82.4% (75/91), 96.7% (58/60), 54.8% (17/31), and 0.6 respectively. The corresponding indices in the ROSE group were 97.4% (74/76), 100.0% (21/21), 97.9% (95/97), 100.0% (74/74), 91.3% (21/23), and 0.9 respectively, those of the mobile phone group were 95.2% (40/42), 100.0% (10/10), 96.2% (50/52), 100.0% (40/40), 83.3% (10/12), and 0.9 respcetively, and those of the self-ROSE group were 100.0% (34/34), 100.0% (11/11), 100.0% (45/45), 100.0% (34/34), 100.0% (11/11), and 1.0 respectively. The sensitivity ( P=0.002), the accuracy ( P=0.001) and the negative predictive value ( P=0.009) of the ROSE group were significantly higher than those of the non-ROSE group, and there was no significant difference in other diagnostic efficacy indices ( P>0.05). There was no significant difference between the mobile phone group and the self-ROSE group in diagnostic efficacy ( P>0.05). Conclusion:Instant smartphone-assisted tele-ROSE through WeChat can well meet the needs of pathologists and endoscopic physicians. After the application of tele-ROSE training, the diagnostic accuracy of endoscopic physicians is equivalent to that of cytopathologist, which helps to obtain more sufficient specimens under endoscopy and improve the diagnostic accuracy of EUS-FNA.
ABSTRACT
Objective:To compare the safety and efficacy of endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) for the treatment of biliary obstruction at different locations.Methods:From January 2016 to June 2021 data of 82 patients with obstructive jaundice treated with EUS-HGS in Nanjing Drum Tower Hospital were reviewed in this retrospective cohort study. According to the location of biliary obstruction,patients were divided into hilar biliary obstruction group ( n=30) and distal biliary obstruction group ( n=52). Univariate and multivariate logistic regression analyses were conducted adjusting covariates to compare the technical success rate, the clinical success rate, the adverse reaction incidence, hospital stay and cost of the two groups. Results:The technical success rates were 93.3% (28/30) and 94.2% (49/52) in the hilar biliary obstruction group and the distal biliary obstruction group with no significant difference between the two groups ( P=0.870, OR=1.17, 95% CI: 0.18-7.41). The clinical success rates were 83.3% (25/30) and 88.5% (46/52) in the hilar biliary obstruction group and the distal biliary obstruction group with no significant difference between the two groups ( P=0.514, OR=1.53, 95% CI: 0.43-5.53). The incidence of adverse events in hilar biliary obstruction group was 10.0% (3/30), including cholangitis 3.3% (1/30), biliary fistula 6.7% (2/30), biliary peritonitis 6.7% (2/30). The incidence of adverse events in patients with distal biliary obstruction was 17.3% (9/52), including cholangitis 9.6% (5/52), biliary fistula 7.7% (4/52) and biliary peritonitis 5.8% (3/52). There was no significant difference in the incidence of adverse events between the two groups ( P>0.05). Conclusion:There is no significant difference in safety or efficacy of EUS-HGS for hilar biliary obstruction and distal biliary obstruction.
