目的 探讨胰十二指肠切除术胰与消化道重建方法的选择。方法 对我院1989～1999年施行的胰十二指肠切除术后胰胃吻合83例行回顾性总结，其中行经典的胰十二指肠切除术76例，保留幽门的胰十二指肠切除术7例。胰胃吻合是残余胰腺与胃后壁间断单层植入式吻合。结果 住院病死率为2.4%（2/83）； 并发症发生率为25.3%（21/83），其中胰瘘3例，胆瘘2例，吻合口出血3例，切口裂开5例，胃排空迟缓5例，腹腔感染1例，胸腔积液1例，肠梗阻1例。结论 胰胃吻合术简便、安全，是降低术后胰瘘的胰肠重建方法。
ObjectiveTo explore the therapeutic effect of gasless endoscopic thyroidectomy via axillary posterior approach for unilateral papillary thyroid microcarcinoma. MethodsThe clinicopathologic data of patients with unilateral papillary thyroid microcarcinoma who were treated by gasless endoscopic thyroidectomy via axillary posterior approach (observation group) or breast approach (control group) in the Xuzhou Central Hospital from January 2020 to February 2022 were collected. The operation time, accidental intraoperative bleeding, exposure time of recurrent laryngeal nerve, number of lymph node dissection, total hospital stay, and postoperative complications such as superior laryngeal nerve injury, cough due to drinking, temporary hoarseness, transient hypocalcemia, tunnel hematoma, and neck discomfort were compared between the two groups. Meanwhile, the cosmetic effects of the two groups were evaluated. ResultsA total of 87 patients who met the study conditions were enrolled in this study, including 47 cases in the observation group and 40 cases in the control group. There were no statistical differences in the baseline data such as gende, age, maximum tumor diameter, location of tumor, etc. between the two groups (P>0.05). Compared with the control group, the exposure time of recurrent laryngeal nerve was shorter (P<0.001) and the number of lymph node dissection was more (P=0.034), but the accidental intraoperative bleeding during operation was more (P=0.015) in the observation group. There were no statistical differences in the operation time and total hospital stay between the two groups (P>0.05). There were no superior laryngeal nerve injury and cough due to drinking in the two groups after operation, and there were no statistical differences between the two groups in the terms of postoperative temporary hoarseness, transient hypocalcemia, and tunnel hematoma (P>0.05), but it was found that the incidence of postoperative neck discomfort in the observation group was lower than that in the control group (P=0.043), and the postoperative cosmetic satisfaction score was also higher than that in the control group (P<0.001). ConclusionsFrom the results of this study, gasless endoscopic thyroidectomy via axillary posterior approach for unilateral papillary thyroid microcarcinoma is safe and feasible. It can quickly expose the recurrent laryngeal nerve and greatly improve the efficiency of lymph node dissection, as well as the cosmetic effect is better.
Objective The purpose of this study was to establish and validate a risk prediction model for post-thrombotic syndrome (PTS) in patients after interventional treatment for acute lower extremity deep vein thrombosis (LEDVT). MethodsA retrospective study was conducted to collect data from 234 patients with acute LEDVT who underwent interventional treatment at Xuzhou Central Hospital between December 2017 and June 2022, serving as the modeling set. Factors influencing the occurrence of PTS were analyzed, and a nomogram was developed. An additional 98 patients from the same period treated at Xuzhou Tumor Hospital were included as an external validation set to assess the reliability of the model. ResultsAmong the patients used to establish the model, the incidence of PTS was 25.2% (59/234), while in the validation set was 31.6% (31/98). Multivariate logistic regression analysis of the modeling set identified the following factors as influencing PTS: age (OR=1.076, P=0.001), BMI (OR=1.163, P=0.004), iliac vein stent placement (OR=0.165, P<0.001), history of varicose veins (OR=5.809, P<0.001), and preoperative D-dimer level (OR=1.341, P<0.001). These 5 factors were used to construct the risk prediction model. The area under the ROC curve (AUC) of the model was 0.869 [95%CI (0.819, 0.919)], with the highest Youden index of 0.568, corresponding to a sensitivity of 79.7% and specificity of 77.1%. When applied to the validation set, the AUC was 0.821 [95%CI (0.734, 0.909)], with sensitivity of 77.4%, specificity of 76.1%, and accuracy of 76.6%. ConclusionsThe risk prediction model for PTS established in this study demonstrates good predictive performance. The included parameters are simple and practical, providing a useful reference for clinicians in the preliminary screening of high-risk PTS patients.
