Evaluation of 18FDG PET-CT-positive mediastinal-hilar lymph nodes in extrathoracic malignancies by EBUS-TBNA; correlation of SUVmax, and short-axis diameter with the final diagnosis

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 short-term effectiveness of ultrasound-guided closed reduction by Kirschner wire provocation technique in the treatment of Salter-Harris types Ⅰ and Ⅱ periosteal entrapment of distal tibial epiphyseal fractures in children and adolescents.@*METHODS@#Between May 2019 and May 2022, 41 patients with Salter Harris types Ⅰ and Ⅱ distal tibial epiphyseal fractures were admitted, all of whom had periosteal entrapment on preoperative MRI, and 38 cases (92.7%) were confirmed to have periosteal entrapment by intraoperative ultrasound. There were 24 males and 14 females, the age ranged from 6.8 to 15.7 years, with an average of 10.7 years; and there were 20 cases of Salter Harris type Ⅰ and 18 cases of type Ⅱ. The time from injury to operation was 22-76 hours, with an average of 28.4 hours. The preoperative imaging examination showed excellent alignment in 4 cases, good in 20 cases, and poor in 14 cases. The ultrasound guided Kirschner wire provocation technique for closed reduction and percutaneous Kirschner wire internal fixation were performed. The operation time, intraoperative fluoroscopy frequency, fracture healing time, and complications were recorded. Anteroposterior and lateral X-ray films of the affected ankle joint were taken before operation, at 3 months after operation, and at last follow-up to observe the healing of the fracture, and anteroposterior X-ray films of the whole length of both lower limbs were taken to evaluate the alignment of the force lines of the affected limbs. The range of motion (ROM), visual analogue scale (VAS) score, and American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score were used to evaluate ankle function. The mechanical lateral distal tibia angle (mLDTA) and the anatomic anterior distal tibia angle (aADTA) were measured.@*RESULTS@#The operation time ranged from 17 to 52 minutes, with an average of 22.6 minutes, and the intraoperative fluoroscopy frequency ranged from 3 to 11 times, with an average of 4.2 times. X-ray examination during operation and at 2 days after operation showed that anatomical reduction was achieved. All patients were followed up 10-24 months, with an average of 16.4 months. All fractures healed in 6.1-7.2 weeks, with an average of 6.3 weeks; no fracture displacement occurred, and the patients recovered to their pre-injury level of motion at 6 months after operation. Needle tail irritation occurred in 2 cases at 4 weeks after operation, and they recovered after symptomatic treatment. During the follow-up, there was no serious complication such as incision deep infection, bone nonunion, delayed union, and malunion. At last follow-up, the patients' alignment were all excellent, and the difference was significant when compared with preoperative one ( Z=-7.471, P<0.001). The VAS score, AOFAS ankle-hindfoot score, dorsiflexion-plantar flexion ROM, varus-valgus ROM, mLDTA, and aADTA significantly improved at 3 months after operation and last follow-up when compared with preoperative ones ( P<0.05).@*CONCLUSION@#Ultrasound-guided closed reduction by Kirschner wire provocation technique for treating Salter-Harris types Ⅰ and Ⅱ periosteal entrapment of distal tibial epiphyseal fractures in children and adolescents is minimally invasive and safe.

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.

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.

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). After treatment, the stone-free rate after the first treatment in the control group was significantly lower than that in the observation group [61.54% (40/65) vs. 78.46% (51/65), χ2 = 4.43, 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]. Intraoperative blood loss in the observation group was significantly lower than that in the control group [(112.65 ± 30.74) mL vs. (170.68 ± 35.67) mL, t = 9.94, P < 0.05]. Serum immunoglobulin G and malondialdehyde levels in the observation group were (8.56 ± 1.74) g/L and (7.74 ± 0.74) mol/L, respectively, which were significantly higher than (7.75 ± 1.68) g/L and (5.21 ± 0.65) mol/L in the control group ( t = 2.70, 20.71, both P < 0.05). Serum immunoglobulin M and superoxide dismutase levels in the observation group were (1.23 ± 0.32) g/L and (71.75 ± 8.57) U/L, which were significantly lower than (1.55 ± 0.45) g/L and (90.64 ± 9.73) U/mL in the control group ( t = -4.67, -11.75, both P < 0.05). Conclusion:B ultrasound-guided extracorporeal shock wave lithotripsy combined with tamsulosin hydrochloride medication is more effective on ureteral calculi than B ultrasound-guided extracorporeal shock wave lithotripsy alone.

Stratifying indeterminate cytology thyroid nodules by combining Thyroid Imaging Reporting and Data Systems (TI-RADS) and The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC)

Objective@#To determine the risk of malignancy of Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) indeterminate Thyroid Nodules (Bethesda III, IV and V) by combining cytologic (TSBRTC) and Thyroid Imaging Reporting and Data Systems (TI-RADS) ultrasonographic features based on final histopathology.@*Methods@#Design: Retrospective review of records. Setting: Tertiary Private Training Hospital. Participants: 551 records. @*Results@#Among 81 eligible participants, 59 out of 84 nodules (70.24%) wer malignant on histopathology. The malignancy risk of Bethesda classification was 60.87% (28 out of 46) for Bethesda III, 57.14% (8 out of 14) for Bethesda IV and 95.83% for Bethesda V. The malignancy risk for TI-RADS categories was 0 % (0/1) for TI-RADS 2, 50% (10 out of 20) for TI-RADS 3, 71.05 % for TI-RADS 4 and 91.67 % for TI-RADS 5. The highest risk of malignancy (100%) was associated with [Bethesda IV/TI-RADS 1, 2, and 3], [Bethesda V/TI-RADS 1, 2 and 3 [Bethesda IV and V/TI-RADS 1, 2 and 3] and [Bethesda IV/TI-RADS 5]. The lowest risk of malignancy (33.33%) was associated with [Bethesda III/TI-RADS1, 2 and 3]. A high Bethesda classification (Bethesda V) was almost 5x more likely to have a malignant anatomorphology compared with Bethesda III (p = .05) while a TI-RADS 4 or 5 category was almost 5x more likely to have a malignant anatomorphology compared to TI-RADS 1, 2 or 3 (p = .026).@*Conclusion@#This study showed that TI-RADS scoring is a sensitive diagnostic classification in recognizing patients with thyroid cancer and combining Bethesda classification and TI-RADS scoring increases the sensitivity in the diagnosis of malignant thyroid nodules. A higher likelihood of malignancy is associated with higher Bethesda classification and TI-RADS scoring.

Influencing Factors and Prediction Model of Performance of Needle Visualization in Fine Needle Aspiration of Thyroid Nodules / 中国医学科学院学报

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.

During the follow-up, no significant difference was found in the rate of nodular residues between the "hydrodissection technique" group and "hydrodissection technique" group (9.8% vs 10.9% (P>0.05).@*CONCLUSIONS@#The "leverage pry-off method" is simple and effective for preventing thermal injury during microwave ablation of benign thyroid nodules.

The use of erector spinae versus transversus abdominis blocks in ovarian surgery: A randomized, comparative study / Uso del bloqueo del plano erector de la espina versus el plano transverso abdominal en cirugía de ovario: un estudio aleatorizado comparativo

Abstract Introduction: Inadequate pain control after major surgery can lead to significant complications. Ultrasound (US) guided plane blocks account for significant progress in regional anesthesia. Objective: This study explored the analgesic superiority of ultrasound-guided erector spinae (ESPB) and transversus abdominis (TAPB) plane blocks in patients undergoing major ovarian cancer surgery under general anesthesia. There have been no previous studies comparing their efficacy under these circumstances. Methods: This double-blind randomized comparative study included 60 patients undergoing major ovarian cancer surgery under general anesthesia. The ESPB group (n=30), received preoperative ultrasound-guided ESPB and the TAPB group (n=30), received preoperative low TAPB. Opioid consumption, HR, MAP, visual analogue scale (VAS) and adverse events were documented over 24 hours after surgery. Results: There was a highly significant difference in tramadol consumption between the two groups, with (95% CI: 16.23 to 50.43) and (95% CI: 59.23 to 95.43) for ESPB and TAPB groups, respectively. A significant difference (P < 0.01) was shown in intraoperative fentanyl consumption with (95% CI: 113 to 135.6) and (95% CI: 141.8 to 167.6) for ESPB and TAPB groups, respectively. A highly significant longer time to first analgesic request was recorded in the ESPB group (95% CI: 5.5 -15.3) (P < 0.001). VAS had a median of 2 (1-3) and 4 (2-6) for ESPB and TAPB groups, respectively, with F(1)=18.15, P=0.001 between groups. Postoperative HR and MAP in the TAPB group were significantly higher with more incidence of PONV. Conclusions: ESPB provided a more reliable analgesia versus TAPB in patients undergoing ovarian cancer surgery.

El grupo del BPEE (n=30), recibió un BPEE guiado por ecografía, mientras que el grupo de BPTA (n=30), recibió un BPTA preoperatorio bajo. El consumo de opioides, la FC, la PAM, la escala visual analógica (EVA) y los eventos adversos, se documentaron durante las 24 horas posteriores a la cirugía. Resultados: Hubo una diferencia estadísticamente significativa en el consumo de tramadol entre los dos grupos, con un IC del 95% de 16,23 a 50,43 y un IC del 95% de 59,23 a 95,43 para los grupos de BPEE y de BPTA respectivamente. Se demostró una diferencia estadísticamente significativa (P < 0,01) en el consumo de fentanilo con un IC del 95%: 113 a 135,6 y un IC de 95%: 141,8 a 167,6 para los grupos de BPEE y BPTA, respectivamente. El tiempo transcurrido hasta la primera solicitud de analgésico en el grupo de BPEE fue significativamente más prolongado (IC 95%: 5,5 -15,3) (P < 0,001). La escala visual analógica - EVA - tuvo una mediana de 2 (1-3) y 4 (2-6) para los grupos del BPEE y BPTA, respectivamente, con F(1)=18,15, P=0,001 entre grupos. La FC y la PAM postoperatorias en el grupo de BPTA fueron significativamente superiores, con una mayor incidencia de nausea y vómito postoperatorios. Conclusiones: El BPEE proporcionó una analgesia más confiable que BPTA, en pacientes sometidas a cirugía de cáncer de ovario.

A comparison of the success rate of radial artery cannulation between the ultrasound?guided and conventional palpation techniques in elderly patients undergoing cardiothoracic surgery

Background:Ultrasound?guided (USG) radial artery cannulation against the standard palpation technique increases the first attempt rate in both pediatric and adult patients. The objective of this study was to evaluate the benefits of USG versus the palpation technique in improving the first attempt rate in elderly patients. Methods: The patients over 65 years of age were randomized to the USG or Palpation group. The radial artery identification in the USG group was performed with the aid of the Sonimage HS 1. In the Palpation group, the radial artery was identified by manual palpation. The operators were cardiothoracic anesthesiologists. Overall success was defined as cannulation completed within 10 min. Results: Eighty patients (40 in each group) were recruited. The respective first attempt and overall success rate for the USG group were similar to the Palpation group (P > 0.999 and P = 0.732). The time to the first attempt and overall success were also similar (P = 0.075 and P = 0.636). The number of attempts, number of catheters used, and failure rates were similar between the groups (P = 0.935, P = 0.938, and P = 0.723). The number of successful cannulations within 10 min was similar for both the groups as categorized by the radial artery diameter (P = 0.169). Conclusions: The USG did not increase the first attempt or overall success rate of radial artery cannulation in the elderly patients undergoing cardiothoracic surgery. The time to first attempt and overall success were similar between both the groups. The number of attempts and number of catheters used were similar between both groups.

Objective:To investigate the safety and efficacy of ultrasound-guided transversus abdominis plane (TAP) combined with paracervical block in percutaneous microwave ablation(PMWA) of uterine fibroids.Methods:Twenty-four patients with uterine fibroids who underwent PMWA after ultrasound-guided TAP combined with paracervical block in Sichuan Cancer Hospital from October 2021 to January 2022 were retrospectively analyzed. The success rate and adverse reactions of TAP combined with paracervical block were recorded, and the types and doses of rescue analgesics used during and after operation were recorded. The pain degree of patients was recorded by NRS(numeric rating scales) during and 30 minutes, 1 hour, 2 hours, 4 hours, 6 hours, 12 hours and 24 hours after operation, and the satisfaction of patients was recorded.Results:The success rate of TAP combined with paracervical block was 100%, and there were no adverse reactions during and after operation. During the operation, 5 patients(20.83%) had mild pain, which was tolerable and did not need intervention, 4 patients(16.67%) presented with moderate pain, and the NRS scores were 4, 4, 5 and 6 respectively, the symptoms were relieved after rescue analgesia. All patients completed one ablation, no ablation failure or secondary ablation. Some patients had mild pain after operation, which could be tolerated without intervention, and all were relieved naturally within 6 hours. All patients returned home on the day of ablation and were 100% satisfied with the analgesic effect.Conclusions:Ultrasound-guided TAP combined with paracervical block in PMWA of uterine fibroids is safe and effective, which is worthy of clinical promotion.

Diagnostic value of endoscopic ultrasonography for pancreatic cystic lesions / 中华胰腺病杂志

Objective:To explore the diagnostic value of endoscopic ultrasonography (EUS) for pancreatic cystic lesions (PCLs).Methods:Clinical data of 211 patients with PCLs, who underwent EUS at least once and were pathologically confirmed in First Affiliated of Naval Medical University from January 2011 to December 2021 was retrospectively analyzed. EUS imaging characteristics, biochemical analysis of cystic fluid and pathological data were recorded. The pathological diagnosis results of intraductal papillary mucinous neoplasms and mucinous cystic neoplasms were included in the mucinous lesion group, while pancreatic pseudocyst, serous cystic neoplasms, solid pseudopapillary neoplasms and pancreatic neuroendocrine tumors were included as non-mucinous lesions group; those with pancreatic ductal adenocarcinoma, adenocarcinoma or with atypical or cancer cells were included as malignant lesion group, and the else were included as benign lesions group. The level of CEA in cyst fluid between mucinous and non-mucinous lesions and the level of amylase in cyst fluid between benign and malignant lesion groups were compared, and the area under the curve (AUC) was calculated by drawing receiver operating characteristic curve (ROC), which was used to analyze the differential diagnosis efficiency of cyst fluid CEA and amylase test indexes. The basic characteristics and EUS imaging characteristics, and the diagnostic efficiency of EUS and liquid-based cytology and histopathology between benign and malignant lesions were studied and analyzed.Results:Among the 211 PCL patients, cyst fluid was obtained in 201 patients, of which 188 patients (93.5%) underwent cytological examination, and 33 patients were diagnosed with an accuracy rate of 17.6%; 41 cases were obtained for histological examination, and 23 cases were confirmed, with an accuracy rate of 56.1%. Among all confirmed cases, 45 cases had benign lesions, including 22 cases of mucinous lesions and 23 cases of non-mucinous lesions, with the cyst fluid CEA of 1458.16(19.80, 1500.00), 4.4(0.50, 341.14)ng/ml respectively, and the difference of cyst fluid CEA level between mucinous and non-mucinous lesions was statistically significant( P<0.05). The cyst fluid CEA<10.15 ng/ml could be used to diagnose non-mucinous PCLs with the sensitivity of 89.5%(95% CI0.686-0.981), and the specificity of 66.7%(95% CI0.438-0.837). The cyst fluid amylase levels in benign and malignant lesions were 379.00(50.00, 18405.50), 42.00(13.50, 340.00)U/L, and the difference was statistically significant ( P<0.05). The cyst fluid amylase>747.50 U/L might help to identify benign PCLs with the sensitivity of 91.7%(95% CI0.646-0.996), and the specificity of 48.0%(95% CI0.300-0.665). EUS showed that the proportion of cyst wall thickening, main duct dilatation and cystic solid components in patients with malignant lesions was significantly higher than that in patients with benign lesions, and the differences were statistically significant ( P<0.05), while there was no significant difference in the proportion of cyst wall nodules and cystic septum between the two groups. The accuracy of EUS combined with liquid-based cytology or histopathology in malignant lesions was over 80%. Conclusions:The cyst fluid CEA level can help to differentiate non-mucinous PCLs from mucinous PCLs, and the cystic amylase level could be useful to identify the benign and malignant PCLs. EUS combined with cytology or histology had high diagnostic value for malignant or potentially malignant PCLs, and EUS-FNA examination can be recommended as soon as possible for those with high-risk factors.

Current status and progress of endoscopic drainage for acute cholecystitis / 中华消化外科杂志

The fundamental treatment for acute cholecystitis is surgical cholecystectomy, especially laparoscopic cholecystectomy. Some high-risk surgical patients need gallbladder drainage. The traditional drainage method is percutaneous transhepatic gallbladder drainage. However, in recent years, two endoscopic approaches, including endoscopic transpapillary gallbladder drainage and endoscopic ultrasound-guided gallbladder drainage, have developed rapidly and have advantages in long-term outcomes. In this article, the authors discuss the historical development, technical characteristics, comparison between methods , adverse events and long-term outcomes of the two endoscopic drainage methods through literature review.
