ObjectiveTo investigate clinical value of MRI examination in diagnosis of xanthogranulomatous cholecystitis (XGC), and to analyze pathologic correlation of various imaging findings. MethodsMRI imaging data of 7 patients with XGC proved by surgery and pathology who underwent entire MRI sequences examination in Sichuan Provincial People's Hospital from Jan. 2013 to Dec. 2015, were analyzed retrospectively. The thickness and contrast enhancement of gallbladder wall, gallbladder wall nodules, completeness of gallbladder mucosa lines, gallbladder stones, and the changes around the gallbladder were focused in every patient. ResultsIn 7 patients with XGC: gallbladder wall thickening occurred in all patients, in which 2 patients were local thickening, 5 patients were diffuse thickening; ‘hypodense band sign' was found by enhance scan in 4 patients; the multiple intramural nodules were presented in 5 patients, which were low signal intensity on T1WI image and high signal intensity on T2WI image; the mucosal lines were continuous in 6 patients and discontinuous in 1 patient; 6 patients combined with cholecystolithiasis. The fat layer around the gallbladder was found fuzz in 7 patients, liver and gallbladder boundaries were not clear in 7 patients; temporal enhancement of arterial phase in liver parenchyma was observed in all patients, and 1 patient combined with liver abscess. Hilar bile duct narrowed and intra-hepatic bile duct dilated in 2 patients, intra-hepatic and extra-hepatic bile duct slightly dilated in 2 patients (lower part of the choledochus stone was found in 1 patient), liver cyst was observed in 3 patients, single or double kidney cyst was observed in 4 patients; all patients were not found intraperitoneal or retroperitoneal swelling lymph nodes. ConclusionMRI examination can accurately describe various imaging features of XGC, so MRI has important value in diagnosis of XGC.

ObjectiveTo predict the risk factors affecting postoperative recurrence of granulomatous lobular mastitis (GLM) in the mass stage by machine learning algorithm, and to provide a reference for the early identification and prevention of postoperative recurrence of GLM in the mass stage. MethodsThe electronic medical records and follow-up data of patients with GLM in the Department of Breast Disease Unit, the First Affiliated Hospital of Henan University of Traditional Chinese Medicine from October 2020 to January 2023 were selected. A total of 340 patients with GLM in the mass stage who met the inclusion and exclusion criteria were selected as the research subjects. According to whether the patients relapsed after surgery, they were divided into recurrence group and non-recurrence group. The collected cases were randomly divided into training set and test set according to the ratio of 7:3. In the training set, the recurrence prediction model was constructed by using traditional logistic regression and three machine learning algorithms: artificial neural network, random forest and XGBoost (extrem gradient boosting). In the test set, the performance of the model was evaluated by sensitivity, specificity, accuracy,positive predictive value, negative predictive value, F1 value and area under the curve (AUC) value. The Shapley Additive exPlanation (SHAP) method was used to explore the important variables that affect the optimal model in identifying postoperative recurrence in the GLM mass phase. The optimal risk cutoff value of the prediction model was determined by the Youden index. Based on this, the postoperative patients in the GLM mass phase of the external test set were divided into high-risk and low-risk groups. ResultsA total of 392 patients who met the GLM mass stage were included, and 52 cases were excluded according to the exclusion criteria, and 340 cases were finally included, including 60 cases in the recurrence group and 280 cases in the non-recurrence group. Based on the results of univariate analysis, correlation analysis and clinically meaningful influencing factors, 12 non-zero coefficient characteristic variables were screened for the construction of the prediction model, and these 12 characteristic variables included other disease history, number of miscarriages, breastfeeding duration of the affected breast, history of milk stasis, lesion location, nipple indentation, fluctuation sensation, low-density lipoprotein, testosterone, previous antibiotic therapy, previous oral hormone medication, and perioperative traditional Chinese medicine treatment duration. The logistic regression prediction model, artificial neural network, random forest and XGBoost prediction models were constructed, and the results showed that the accuracy, positive predictive value and negative predictive value of the four prediction models were all >75%, among which the XGBoost model had the best performance, with accuracy, specificity, sensitivity, AUC, positive predictive value, negative predictive value and F1 values of 0.93, 0.99, 0.65, 0.87, 0.92, 0.93 and 0.76, respectively. SHAP method found that the duration of traditional Chinese medicine treatment during perioperative period, the duration of breast-feeding on the affected side, low density lipoprotein, testosterone and previous hormone drugs were the top five factors affecting XGBoost model to identify postoperative recurrence of GLM in mass stage. ConclusionsCompared with the traditional Logistic regression prediction model, the models based on machine learning for identifying postoperative recurrence in the GLM mass phase showed better performance, among which the XGBoost model performed best. Targeted preventive measures can be given based on the above risk factors to improve the postoperative prognosis of the GLM mass phase.
Objective To evaluate the clinical role of video-assisted mediastinoscopy and its safety and effectiveness in the diagnosis of thoracic disease. Methods We reviewed the clinical data of consecutive 40 patients (25 males and 15 females with an average age of 54.6 years) who received video-assisted mediastinoscopic surgery in our department of thoracic surgery from December 2011 to November 2016, including mediastinal lymph node biopsy in 27 patients, mediastinal primary lesions biopsy in 8, bronchial cystectomy in 3 and esophageal dissection in 2. Results The histological results were positive in 20 patients (73.1%) in mediastinal lymph node biopsy, including granulomatous mediastinitis in 14 and metastasis in 6 (non-small cell lung cancer in 4, Ewing sacoma in 1 and small cell lung cancer in 1) and reactive proliferation in 7 (26.9%). In mediastinal primary lesions biopsy, the accuracy rate of diagnosis was 100.0%. The pathologic results were malignant in all patients, including small cell lung cancer in 5, adenoid cystic carcinoma in 1, squamous carcinoma in 1 and adenocarcinoma in 1. In patients who received the bronchial cystectomy, no recurrence was found during at least 2 years follow-up. There was one patient with severe complication (innominate artery injury). Two patients suffered transient laryngeal recurrent nerve palsy with hoarseness and two patients incision secretion. Conclusion Video-assisted mediastinoscopic surgery is effective and safe and dissection should be careful in granulomatous mediastinitis to avoid the great vessel injures.
ObjectiveTo analyze therapeutic effect of ultrasound-guided vacuum-assisted rotary excision with tube irrigation drainage in treatment of granulomatous mastitis (GM).MethodsThe clinical data of 120 patients with GM from January 2018 to December 2018 in the Renmin Hospital of Wuhan University were analyzed. Sixty patients were treated with the ultrasound-guided vacuum-assisted rotary excision with tube irrigation drainage (control group), and the other 60 patients were treated with the metronidazole solution combined with dexamethasone on the basis of the control group (observation group). The therapeutic period, total effective rate, postoperative appearance of breast, and recurrence rate were analyzed. While the pathogenic bacteria was analyzed by the microbial culture and the pathogen gene detection.ResultsThere were no significant differences in the baseline data between the two groups (P>0.05). The ultrasound-guided vacuum-assisted rotary excisions were successfully performed in all 120 patients. The therapeutic period of the observation group was shorter than that of the control group (t=–3.633, P<0.001). The total effective rate and rate of excellent and good of postoperative breast appearance had no significant differences between the two groups (total effective rate: 96.7% versus 90.0%, χ2=1.922, P=0.166; rate of excellent and good of postoperative breast appearance: 96.7% versus 88.3%, χ2=1.205, P=0.272). The recurrence rate of the observation group was lower than that of the control group (χ2=5.175, P=0.023). The positive rates of bacteria were 25.8% and 58.8% in the 120 cases by the microbial culture and 52 cases by the pathogen gene detection, respectively, which had a statistical difference (χ2=16.974, P<0.001), the same conclusions were obtained in the observation group and the control group (χ2=6.691, P=0.010; χ2=9.379, P=0.002).ConclusionsUltrasound-guided vacuum-assisted rotary excision with tube irrigation drainage is well applied in treatment of GM. It could maintain a good shape of breast. Use of metronidazole solution combined with dexamethasone after surgery could shorten therapeutic period and reduce recurrence rate.
