ABSTRACT

Liver disease is one of the most important health problems around the world, and early diagnosis and timely intervention and treatment are the key to preventing liver-related morbidity and mortality rates. The development of endoscopic techniques has provided new diagnostic and intervention methods for liver diseases. This article reviews the application and development of endoscopic techniques in liver diseases from the following aspects: the technical advances and advantages of endoscopic ultrasound-guided liver biopsy; the application and development of endoscopic techniques in the treatment of portal hypertension caused by liver abscess/hepatic cyst and liver diseases, as well as interventional techniques in the treatment of liver tumors; the efficacy and prospects of the endoscopic techniques for weight loss, which are relatively new in China, in the treatment of nonalcoholic fatty liver disease/nonalcoholic steatohepatitis. Endoscopic techniques may hold promise for wide clinical application and exploration in in liver-related diseases in China, so as to provide more options for patients and doctors.

ABSTRACT

ObjectiveTo investigate the efficacy, safety, and cost-effectiveness of endoscopic ultrasound (EUS)-guided coil placement combined with tissue adhesive injection in the treatment of gastric varices with spontaneous shunt. MethodsA retrospective analysis was performed for the patients with acute gastric variceal bleeding and spontaneous portosystemic shunt who were hospitalized and received balloon-occluded retrograde transvenous obliteration (BRTO) combined with endoscopic tissue adhesive injection or EUS-guided coil placement combined with tissue adhesive injection in Xiangyang Central Hospital from March 2019 to September 2022. The two surgical procedures were compared in terms of efficacy (technical success rate, 5-day rebleeding rate, 1-year rebleeding rate, and time to rebleeding), safety (the incidence rate of ectopic embolism, the amount of tissue adhesive used, and the amount of lauromacrogol used), and cost-effectiveness (hospital costs and length of hospital stay). The t-test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups. The Kaplan-Meier method was used to estimate the rebleeding. The chi-square test was used for comparison of categorical data between two groups. ResultsA total of 25 patients received successful EUS-guided coil placement and tissue adhesive injection, with a technical success rate of 100%, a median amount of 2.5 mL tissue adhesive used, a median amount of 11.0 mL lauromacrogol used, a mean length of hospital stay of 14.88±3.21 days, a mean hospital cost of 32 660.00±4 602.07 yuan, and a 5-day rebleeding rate of 0%; among these patients, 2 were lost to follow-up, and 23 patients with complete follow-up data had an incidence rate of ectopic embolism of 0% and a median time to rebleeding of 689 days. A total of 14 patients underwent modified BRTO combined with endoscopic tissue adhesive injection, with a technical success rate of 100%; a median amount of 5.0 mL tissue adhesive used during surgery, which was significantly higher than that used in EUS (U=39.000, P<0.001); a median amount of 10.5 mL lauromacrogol used during surgery; a mean length of hospital stay of 15.38±4.94 days; a mean hospital cost of 57 583.47±18 955.40 yuan, which was significantly higher than that used in EUS (t=-6.310, P<0.001); a 5-day rebleeding rate of 0%. No patient was lost to follow-up, and all 14 patients had an incidence rate of ectopic embolism of 0% and a median time to rebleeding of 244.50 days, with no significant difference between the two groups (χ2=1.448, P=0.229). ConclusionEUS-guided coil placement combined with tissue adhesive injection is a relatively safe and effective technique for the treatment of gastric variceal bleeding and has a high technical success rate, a low incidence rate of serious adverse events, and similar efficacy to BRTO, with higher safety and cost-effectiveness.

ABSTRACT

@#Gastric adenocarcinoma presenting as a submucosal tumor (SMT) accounts to only 0.1% to 0.63%. A 56-year-old Filipino male presenting with new onset melena underwent magnifying endoscopy, narrow-band imaging, endoscopic ultrasound, and computed tomography revealing a 2.5 cm x 2.0 cm polypoid SMT-like lesion at the fundus. Total gastrectomy with lymph node dissection and esophagojejunostomy was performed with histopathology showing adenocarcinoma. This suggests the need for different modalities to ensure the accuracy of diagnosis and the need for subsequent invasive treatments.

ABSTRACT

Background and Objectives@#The benefits of rapid on-site evaluation (ROSE) of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) of solid masses have not been convincingly shown in large, randomized trials. New equipment using EUS-guided fine needle biopsy (FNB) allows for more material to be acquired that may obviate the need for ROSE. This study aimed to evaluate if EUS-FNB without ROSE was non-inferior to EUS-FNA with ROSE in solid pancreatic masses (SPMs). @*Methods@#Patients with SPMs requiring tissue sampling were randomly assigned to undergo either EUS-FNA with ROSE or EUS-FNB without ROSE. The touch-imprint cytology technique was used to perform ROSE. The primary endpoint was diagnostic accuracy and secondary endpoints were specimen quality, complication rates, and procedure time. @*Results@#Seventy-eight patients were randomized and analyzed (39 EUS-FNA with ROSE and 39 EUS-FNB without ROSE). Non-significantly different diagnostic accuracies were noted in both groups (97% with ROSE and 100% without ROSE, P < 0.371). The bloodiness of histologic samples and complication rates were not significantly different between groups. A significantly shorter mean sampling procedural time was noted for EUS-FNB over EUS-FNA with ROSE (30.4 ± 10.4 vs 35.8 ± 9.8 minutes, P < .02). @*Conclusions@#EUS-FNB demonstrated equal diagnostic accuracy with shorter procedure times in evaluating SPMs compared to EUS-FNA with ROSE. These new-generation FNB needles may obviate the need for ROSE.

ABSTRACT

ABSTRACT Background: Reports of the impact of the 2020 COVID-19 pandemic period/2020 on endoscopic ultrasound (EUS) are scarce. Objective: We analyzed the impact of the pandemic period/2020 on the demographics, indications, and number of diagnostic EUS (D-EUS) and interventional EUS (I-EUS) procedures performed in a high-volume endoscopy unit compared with the previous non-pandemic period/2019. Methods: We retrospectively reviewed the medical records of all patients undergoing D-EUS or I-EUS from March 1, 2019, to February 29, 2020 (non-pandemic period/2019) and from March 1, 2020, to February 28, 2021 (pandemic period/2020). Data compared between the study periods included sex, age, comorbidities, EUS findings and diagnosis, need for interventional procedures during EUS, and adverse events (AEs). Results were significant at P<0.05. Results: EUS procedures decreased from 475 in the non-pandemic period/2019 to 289 in the pandemic period/2020, accounting for a 39% reduction. In non-pandemic period/2019, 388 (81.7%) D-EUS and 88 (18.5%) I-EUS were performed, against 206 (71.3%) D-EUS and 83 (28.7%) I-EUS in pandemic period/2020 (P=0.001). Only 5/289 (1.7%) patients had COVID-19. Fewer patients with comorbidities underwent EUS during pandemic period/2020 due to lockdown measures (P<0.001). D-EUS decreased, whereas I-EUS increased (P<0.001). EUS-guided tissue acquisition (EUS-TA) was the most common I-EUS, performed in 83/289 (28.7%) patients in pandemic period/2020, against 88/475 (18.5%) in non-pandemic period/2019 (P=0.001). AEs did not differ significantly between the study periods. Conclusion: Pandemic Period/2020 had a moderate impact on reducing EUS procedures due to the risks involved. Although I-EUS increased, EUS-related AEs did not. Solid and cystic pancreatic tumors remained a major indication for EUS-TA even during the pandemic period/2020.


RESUMO Contexto: Os dados sobre o impacto da pandemia de COVID-19 2020 na ultrassonografia endoscópica (EUS) são escassos. Objetivo: Analisamos o impacto do período pandêmico/2020 na demografia, indicações e número das EUS diagnósticas (D-EUS) e intervencionistas EUS (I-EUS) realizados em uma unidade de endoscopia de alto volume e os comparamos com o período imediatamente anterior não-pandêmico/2019. Métodos: Revisamos retrospectivamente os prontuários de todos os pacientes submetidos a D-EUS ou I-EUS de 1 de março de 2019 a 29 de fevereiro de 2020 (período não-pandêmico/2019) e de 1º de março de 2020 a 28 de fevereiro de 2021 (período da pandemia/2020). Comparamos os dados entre os períodos do estudo incluímos o sexo, idade, comorbidades, achados e diagnóstico da EUS, necessidade de procedimentos intervencionistas durante a EUS e a ocorrência de eventos adversos (EAs). Os resultados foram significativos com P<0,05. Resultados: O número de ecoendoscopias diminuíram de 475 no período não-pandêmico/2019 para 289 no período pandêmico/2020, representando uma redução de 39%. No período não-pandêmico/2019 e pandêmico/2020 foram realizados 388 (81,7%) D-EUS e 88 (18,5%) I-EUS, contra 206 (71,3%) D-EUS e 83 (28,7%) I-EUS, respectivamente (P=0,001). Apenas 5/289 (1,7%) pacientes tinham COVID-19. Menos pacientes com comorbidades realizaram EUS durante o período pandêmico/2020 devido as medidas de bloqueio (P<0,001). D-EUS diminuiu, enquanto I-EUS aumentou (P<0,001). A EUS associada a aquisição tecidual (EUS-AT) foi a I-EUS mais comum, realizada em 83/289 (28,7%) pacientes no período pandêmico/2020, versus 88/475 (18,5%) no período não-pandêmico/2019 (P=0,001). Os EAs não diferiram significativamente entre os períodos do estudo. Conclusão: O período da pandemia/2020 teve impacto moderado na redução da EUS devido aos riscos envolvidos. Embora o I-EUS tenha aumentado, os EAs relacionados ao EUS não aumentaram. Os tumores pancreáticos sólidos e císticos permaneceram como uma das principais indicações para EUS-AT mesmo durante o período pandêmico/2020.

ABSTRACT

Introduction: Endoscopic ultrasound (EUS)-guided drainage and luminal-apposing metal stents (LAMS) are the options for managing symptomatic pancreatic pseudocysts. Aim: To evaluate the effectiveness and safety of LAMS for EUS-guided drainage of symptomatic pancreatic pseudocysts in two referral centers in Colombia. Materials and methods: A multicenter prospective cohort study between June 2019 and December 2021 included 13 patients diagnosed with symptomatic pancreatic pseudocysts who underwent EUS-guided drainage with LAMS. Technical success, clinical success, and successful stent removal were evaluated as outcomes. Safety outcomes included stent-related adverse events and general adverse events. Follow-up was carried out for eight weeks, collecting data on stent removal. Results: The average age was 53.4 years; 8/13 were men. The mean size of the pseudocyst was 9.56 ± 2.3 cm. Technical success was 100%, and clinical success was 92.3%. The stents were removed on average after 8 ± 2 weeks. The mean procedural time from puncture to stent deployment was 3.2 ± 2.4 minutes. In the imaging check-up, the collections had adequate drainage in all cases. There was a low frequency of complications; bleeding was documented in one case requiring surgery. Conclusions: LAMS is safe and effective in managing symptomatic pancreatic pseudocysts, reducing hospital stay and cost overruns. Clinical symptomatology prevails in the surgery decision.

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

Background : Gall Bladder Polyps are mucosal lesions that project from the Gall Bladder wall into the Gallbladder lumen. They form morphologically distinct lesion/s with internal characteristics different than that of neighboring structures as verified by microscopic examination. About 4-6% are picked up clinically, 2-12% in Cholecystectomy specimens and 4% on Ultrasound. Materias and Methods : A three calendar year retrospective single surgical unit study compromised of 1442 cholecystectomies performed for benign Gall Bladder Disease. The patient were subjected to Ultrasound of abdomen for diagnosis and routine clinic work up. The Gall Bladders Harboring Polyps were examined grossly for site ,number, and microscopy for histological details. Results : In a total number of 40 cases of Gall Bladder Polyp, females outnumbered males. This series spreads over age groups of 3rd decade - 9th decade, most of the patients were seen in 6th decade of life. Youngest patients were 27 years old and oldest one was 85 years old. Incidentally, none of the old patients had evidence of malignancy on histopathology in their Gall Badder Polyp, only 2% were necessitated for a pre-operative diagnosis of Gall Bladder Polyps alone. Rest required it for presence of Gallstones with or without Polyp. None of >10mm size showed any malignant change on histopathological examination. On the Contrary, among the polypoid lesions <10mm size, one polypid lesion (7mm) showed a malignant change (Carcinoma in situ) Conclusion : A predictive model for neoplastic potential of Gall Bladder Polyp may support clinical decision to achieve an ideal therapeutic outcome. Hence a need for reappraisal of management guidelines.

ABSTRACT

ABSTRACT Objectives: To explore the clinical value of preferred ultrasound endoscopic guided biliary drainage in patients with extrahepatic biliary obstruction with intrahepatic biliary ectasis. Methods: A total of 58 patients with malignant obstruction and intrahepatic bile duct expansion, including 32 males, 26 females and median age 65 (58-81) were selected. A prospective randomized controlled study was randomized into EUS-AG and ERCP-BD, with 28 patients in EUS-AG and 30 in ERCP-BD. The efficacy of the two treatments, operation success rate, operation time, the incidence of complications, hospitalization days, cost, unimpeded stent duration, and survival time were compared. Results: 1) The surgical success rate in group EUS-AG was 100%, and in group, ERCP-BD was 96.67%. There was no statistical difference in surgical success rate in the two groups (p>0.05). 2) Average operating time in EUS-AG was (23.69±11.57) min, and in ERCP-BD was (36.75±17.69) min. The difference between the two groups has statistical significance (p<0.05). 3) The clinical symptoms of successful patients were significantly relieved. Compared with the preoperative procedure, the differences in group levels had statistical significance (p<0.05); TBIL, ALP, WBC and CRP levels, no statistical significance difference in groups (p>0.05). Conclusion: EUS-AG operation has short time, low incidence of complications, safe, effective, and can be used as the preferred treatment plan for patients with extrahepatic biliary duct malignant obstruction associated with intrahepatic biliary duct expansion; EUS-AG operation has more unique clinical advantages for patients with altered gastrointestinal anatomy or upper gastrointestinal obstruction.

ABSTRACT

Objective:To investigate the safety and efficacy of endoscopic ultrasound-guided coil embolization for gastric varices.Methods:Patients with portal hypertension who received endoscopic ultrasound-guided coil embolization for the prophylaxis of gastric variceal bleeding between November 2016 and August 2020 at Zhongshan Hospital, Fudan University were included in the study. The primary evaluation index was the post-operative loss of blood flow in gastric varices, and the secondary indices included the safety of coil embolization, rebleeding rate, portal vein thrombosis changes and patient survival.Results:A total of 13 patients with isolated gastric varices and portal systemic shunt were enrolled, including 6 males and 7 females with the median age of 58 years. The median maximum diameter of the target vessel was 40 mm and the median number of coils used was 2.7. All puncture sites were in the lower part of the esophagus near the cardia, and no active bleeding occurred after deployment of coils. Flow in the gastric varices were confirmed absent by Doppler imaging. In a median follow-up period of 403 days, 2 patients had rebleeding, with the one-year rebleeding rate of 9.1%.Two patients developed portal venous thrombosis after the operation. Two patients died, and the one-year survival rate was 90.0%.Conclusion:Endoscopic ultrasound-guided coil embolization might be an effective option for the treatment of isolated gastric varices with portal systemic shunts.

ABSTRACT

Objective:To evaluate the efficacy and safety of endoscopic ultrasound (EUS)-guided coil embolization combined with endoscopic cyanoacrylate injection for gastric fundal varices with large spontaneous shunt.Methods:Data of 24 patients with gastric fundal varices with large spontaneous shunt (the smallest diameter was 5-15 mm) treated by EUS-guided coil embolization combined with endoscopic cyanoacrylate injection in Renmin Hospital of Wuhan University from December 2016 to December 2020 were retrospectively analyzed. The short-term efficacy (the rates of technical success, five-day rebleeding and six-week mortality) and long-term efficacy (the rates of one-year rebleeding, one-year mortality and three-year mortality) and safety (ectopic embolism) were evaluated.Results:The technical success rate was 91.7% (22/24), and the five-day rebleeding rate was 0 (0/22). Computed tomography angiography of portal vein reexamined 2 days after the treatment showed embolism of splenic vein in 1 patient (4.5%). The median follow-up time was 14.9 months (ranging 1.0-48.6 months) and 2 patients were lost during follow-up. The six-week mortality was 0 (0/20), and the one-year rebleeding rate was 35.0% (7/20). Among 12 patients who underwent endoscopy in the follow-up, 5 had aggravation of esophageal varices, and 5 had aggravation of portal hypertension gastropathy. The one-year and three-year mortalities were 5.0% (1/20) and 20.0% (4/20), respectively, neither of which was related to such events as bleeding or ectopic embolism.Conclusion:EUS-guided coil embolization combined with endoscopic cyanoacrylate injection for gastric fundal varices with large spontaneous shunt is effective and safe in short term, with a low rate of ectopic embolism. Long-term efficacy and safety need to be further confirmed.

Objective:To evaluate the safety and feasibility of double endoscopic bypass, namely endoscopic ultrasound-guided gastroenterostomy (EUS-GE) combined with endoscopic ultrasound-guided biliary drainage (EUS-BD), for malignant gastric outlet and biliary obstruction.Methods:A retrospective analysis was conducted on data of 10 patients with malignant gastric outlet and biliary obstruction who were not suitable for surgery or endoscopic retrograde cholangiopancreatography (ERCP) and treated by double endoscopic bypass in Nanjing Drum Tower Hospital from August 2017 to October 2020. The completion of therapy, clinical efficacy and post-procedure adverse events were analyzed.Results:Ten patients with different malignant cancer successfully underwent EUS-GE and EUS-BD, with procedure time of 60.5±22.3 min (30-100 min). There were no postoperative adverse events. EUS-GE was clinically successful in all 10 cases. Of the 10 EUS-BD cases, 9 were clinically successful, and 1 did not meet the criteria of clinical success. The median follow-up was 71 (37-120) days. None of the 10 patients had recurrent gastric outflow tract obstruction or biliary tract obstruction.Conclusion:Double endoscopic bypass is feasible and effective for patients with malignant gastric outlet and biliary obstruction and without surgery or ERCP opportunity.

ABSTRACT

Objective:To evaluate the efficacy and safety of the second session of endoscopic ultrasound-guided lauromacrogol ablation (EUS-LA) for pancreatic cystic neoplasms (PCNs).Methods:A total of 74 patients with suspected of PCNs who underwent EUS-LA in the First Medical Center of Chinese PLA General Hospital from April 2015 to December 2020 were enrolled in the study. Fifteen of them underwent the second ablation. The efficiency of EUS-LA was determined based on the change of lesion volume during the imaging follow-up, categorized into complete resolution (CR), partial resolution (PR) and stable disease (SD). The safety was determined by the complication incidence.Results:Among the 15 patients undergoing the second EUS-LA, there were 9 males and 6 females with age of 51.5±17.6 years. Thirteen patients completed imaging follow-up after the second EUS-LA, CR was achieved in 8 patients, PR in 2 patients and 3 in SD. The CR rate increased from 0 after the first ablation to 8/13 after the second ablation ( P=0.002). The median cyst diameter decreased from 22.0 mm before the second ablation to 15.0 mm after the second ablation ( Z=-2.666, P=0.008) and the median cyst volume reduced from 2 419.7 mm 3 to 1 099.5 mm 3 ( Z=-2.134, P=0.033). The complication incidence of the second ablation was 2/15, similar to that of the first ablation. Conclusion:The second ablation is effective and safe without increasing the complication incidence in patients without achieving CR after the first EUS-LA.

ABSTRACT

To evaluate the diagnostic value and safety of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) in patients with biopsy-negative malignant gastrointestinal stricture, a retrospective analysis was performed on data of patients whose computed tomography scan showed gastrointestinal malignant tumor with complete lumen stricture and endoscopic biopsy results showed negative, who underwent EUS-FNA in the Second Affiliated Hospital of Soochow University from July 2016 to January 2020. Perioperative complications, technical success rate and accuracy of EUS-FNA were analyzed. Eleven cases included in the study, including 7 males and 4 females, with mean age of 60.3 years. There were 8 esophageal strictures and 3 rectal strictures. All patients successfully underwent EUS-FNA, and malignant tumor was found in 10 cases and no tumor cell was found in 1 case. No complications were reported. EUS-FNA is a safe and valuable approach to diagnosing biopsy-negative malignant gastrointestinal strictures.

ABSTRACT

Objective:To investigate the application value of endoscopic ultrasound (EUS) in tumor staging of adenocarcinoma of the esophagogastric junction (AEG) after neoadjuvant concurrent chemoradiotherapy.Methods:The clinical data of 40 patients diagnosed with stage Ⅲ AEG and treated with neoadjuvant concurrent chemoradiotherapy from January 2016 to December 2021 in the First Affiliated Hospital of Hebei North University were retrospectively analyzed. EUS was used to perform preoperative tumor staging after neoadjuvant concurrent chemoradiotherapy to evaluate the therapeutic effect, and the consistency between EUS and postoperative pathological staging was analyzed.Results:In 40 AEG patients after neoadjuvant chemoradiotherapy, the EUS staging was stage yp-uT 2 in 12 cases, stage yp-uT 3 in 18 cases, and stage yp-uT 4 in 10 cases. The postoperative pathological staging was stage pT 1 in 2 cases, stage pT 2 in 14 cases, stage pT 3 in 12 cases, and stage pT 4 in 12 cases. Taking postoperative pathological results as the gold standard, the accuracy of EUS for T staging after neoadjuvant chemoradiotherapy was 62.5%, and the accuracy, sensitivity and specificity for stage T 2 were 58.3%, 50.0% and 80.8%, respectively. The accuracy, sensitivity and specificity for stage T 3 were 61.1%, 91.7% and 75.0%, respectively. The accuracy, sensitivity and specificity for stage T 4 were 70.0%, 58.3% and 89.3%, respectively. The Kappa value of the consistency test between yp-uT staging and pT staging was 0.453. The EUS staging of lymph nodes was stage yp-uN 0 in 15 cases, stage yp-uN 1 in 10 cases, stage yp-uN 2 in 10 cases, and stage yp-uN 3 in 5 cases. The postoperative pathological staging was stage pN 0 in 18 cases, stage pN 1 in 7 cases, stage pN 2 in 7 cases, and stage pN 3 in 8 cases. Taking postoperative pathological results as the gold standard, the accuracy rate of EUS for N staging after neoadjuvant chemoradiotherapy was 57.5%, and the accuracy, sensitivity and specificity of EUS for stage N 0 were 73.3%, 61.1% and 81.8%, respectively. The accuracy, sensitivity and specificity for stage N 1 were 50.0%, 71.4% and 84.8%, respectively. The accuracy, sensitivity and specificity for stage N 2 were 40.0%, 57.1% and 81.8%, respectively. The accuracy, sensitivity and specificity for stage N 3 were 60.0%, 37.5% and 93.8%, respectively. The Kappa value of the consistency test between yp-uN staging and pN staging was 0.409. Conclusions:EUS is not accurate for T staging in patients with stage Ⅲ AEG after neoadjuvant therapy, but has high sensitivity for stage T 3 and high specificity for stage T 4. EUS has low sensitivity for N staging in patients with stage Ⅲ AEG after neoadjuvant therapy, but has high specificity for stage N 3.

ABSTRACT

Objective:To construct a deep learning-based diagnostic system for gastrointestinal submucosal tumor (SMT) under endoscopic ultrasonography (EUS), so as to help endoscopists diagnose SMT.Methods:From January 1, 2019 to December 15, 2021, at the Digestive Endoscopy Center of Renmin Hospital of Wuhan University, 245 patients with SMT confirmed by pathological diagnosis who underwent EUS and endoscopic submucosal dissection were enrolled. A total of 3 400 EUS images were collected. Among the images, 2 722 EUS images were used for training of lesion segmentation model, while 2 209 EUS images were used for training of stromal tumor and leiomyoma classification model; 283 and 191 images were selected as independent test sets to evaluate lesion segmentation model and classification model, respectively. Thirty images were selected as an independent data set for human-machine competition to compare the lesion classification accuracy between lesion classification models and 6 endoscopists. The performance of the segmentation model was evaluated by indexes such as Intersection-over-Union and Dice coefficient. The performance of the classification model was evaluated by accuracy. Chi-square test was used for statistical analysis.Results:The average Intersection-over-Union and Dice coefficient of lesion segmentation model were 0.754 and 0.835, respectively, and the accuracy, recall and F1 score were 95.2%, 98.9% and 97.0%, respectively. Based on the lesion segmentation, the accuracy of classification model increased from 70.2% to 92.1%. The results of human-machine competition showed that the accuracy of classification model in differential diagnosis of stromal tumor and leiomyoma was 86.7% (26/30), which was superior to that of 4 out of the 6 endoscopists(56.7%, 17/30; 56.7%, 17/30; 53.3%, 16/30; 60.0%, 18/30; respectively), and the differences were statistically significant( χ2=7.11, 7.36, 8.10, 6.13; all P<0.05). There was no significant difference between the accuracy of the other 2 endoscopists(76.7%, 23/30; 73.3%, 22/30; respectively) and model(both P<0.05). Conclusion:This system could be used for the auxiliary diagnosis of SMT under ultrasonic endoscope in the future, and to provide a powerful evidence for the selection of subsequent treatment decisions.

ABSTRACT

To evaluate the clinical efficacy and safety of Hot AXIOS, a novel luminal metal stent with a cautery system guided by endoscopic ultrasound, for the treatment of infected pancreatic necrosis (IPN), 5 cases of IPN treated with endoscopic ultrasound-guided Hot AXIOS placement in Hangzhou First People's Hospital from December 2021 to January 2022 were retrospectively analyzed. The results showed that all 5 cases successfully completed the treatment, with 8-21 minutes of the operation time. The symptoms of abdominal pain and bloating on the first day after operation were significantly relieved, and the abdominal CT showed that the walled-off necrosis was significantly reduced. After 2-9 times of direct endoscopic necrosectomy, supplemented by antibiotics, patient's temperature and blood inflammatory indexes returned to normal, the cavity was reduced and necrosis was removed. The Hot AXIOS stent was indwelled for 12-40 days and then removed. After 25-113 days of the follow-up, all patients survived without recurrence. Preliminary results suggest that endoscopic ultrasound-guided Hot AXIOS placement is safe and effective for the treatment of IPN.
