Objective:To compare the surgical outcomes between scarless endoscopic thyroidectomy-lateral neck dissection (SET-LND) and open LND for papillary thyroid cancer (PTC) with lymph node metastasis and to share the experience in the prevention and treatment of lymphatic leakage after LND.Methods:Totally 90 PTC patients (25 males) who underwent LND in the Second Affiliated Hospital of Zhejiang University School of Medicine from Jan. 2021 to Aug. 2022 were retrospectively enrolled, with an average age of (28.06±4.89) years. They were divided into the SET-LND group ( n=50) and the open LND group ( n=40). The intraoperative blood loss, operation time, drainage volume on the first and the second days, postoperative lymphatic leakage, tumor (T), and node (N) were observed. The categorical variable data were compared between groups by χ 2 test, and the continuous variable data confirming normal distribution were compared between groups by independent sample t-test. Results:The operation time of the SET-LND group was (284.00±74.65) min, significantly longer than that of the open LND group (145.38±43.26) min ( t=-10.42, P<0.001). The intraoperative blood loss ( t=-1.309, P=0.194), postoperative hospital stay ( t=-0.136, P=0.892), drainage volume on the first day ( t=-1.074, P=0.286), and drainage volume on the second day ( t=-1.595, P=0.114), postoperative lymphatic leakage ( χ2=0.001, P=0.989), T ( t=0.367, P=0.714), N ( t=-1.614, P=0.110) were not significantly different between the two groups. Conclusion:Two surgical methods of LND have similar therapeutic effects and no significant difference was observed in the incidence of postoperative lymphatic leakage between the two groups.
RÉSUMÉ
Lymphatic leakage and lymphatic cysts are common complications after radical resection of middle- and high-risk prostate cancer. There are many treatment methods but the effect is not accurate. This article reports two patients who were diagnosed by lipiodol lymphangiography under ultrasound guidance and used a mixture of n-butyl cyanoacrylate and lipiodol to embolize lymphatic leakage. Among them, one patient achieved success after one session of interventional embolization. Another patient achieved success after 3 interventions and embolization. Two patients had no complications related to lymphatic interventional therapy, and no lymphatic leakage recurred during the 3-month follow-up. Ultrasound-guided lymphangiography and lymphatic embolization through the inguinal lymph nodes are a feasible option for the treatment of refractory lymphoma leakage

Objective:To explore the risk factors of lymphatic fistula after radical gastric cancer operation.Methods:We retrospectively analyze the clinicopathological data of gastric cancer patients who underwent radical surgery from May, 2019 to May, 2020 at the Third Department of Surgery, Fourth Hospital of Hebei Medical University, and analyze the risk factors impacting postoperative lymphatic leakage,for the establishment of the risk prediction scoring model.Results:A total of 487 patients with gastric cancer underwent radical gastrectomy, of which 32 patients (6.6%) had lymphatic leakage . Multivariate logistic regression analysis showed that hypoproteinemia before surgery (95% CI: 1.222-7.357, P=0.016), the lesion is located in the cardia-fundus of the stomach (95% CI: 1.117-6.788, P=0.028),stage T3-T4 (95% CI: 1.149-25.676, P=0.033), operation time ≥4 h (95% CI: 1.469-11.480, P=0.007), combined organ resection (95% CI: 1.106-12.886, P=0.034), D2+ lymph node dissection (95% CI: 1.969-11.510, P=0.001), anemia (95% CI: 1.271-9.392, P=0.015) were an independent risk factors. Equation based on multi-factor Logistic regression: logit( P)=-9.624+1.098×X 1+1.013×X 2+1.692×X 3+1.413×X 4+1.328×X 5+1.560×X 6+1.240×X 7 was estaslished, using Hosmer. Lemeshow test detects the goodness of fit of the regression equation ( P=0.348). The area under the ROC curve was 0.856 (95% CI: 0.787-0.926, P<0.001); the probability of lymphatic leakage when scores ≥4 points was 14.1%, when scores <4 points ,the probability of leakage was 2.5%. Conclusion:A risk prediction scoring model for lymphatic leakage after radical gastrectomy, can identify patients with high risk after surgery

Objective:To examine the incidence of lymphatic leakage after pediatric liver transplantation and explore the diagnosis and treatment of lymphatic leakage.Methods:From January 1, 2016 to December 31, 2019, clinical data were analyzed retrospectively for 805 pediatric liver transplant recipients. Based upon the diagnosis of lymphatic leakage, they were divided into two groups of lymphatic leakage ( n=271) and lymphatic non-leakage ( n=534). Analyzing the incidence of lymphatic leakage after liver transplantation in children, evaluating the treatment plan, comparing survival rate and the incidence of postoperative complications between two groups. Results:The incidence of lymphatic leakage was 33.7%(271/805); the proportion of partial liver donors was 14.8% in lymphatic leakage group and 25.8% in lymphatic non-leakage group ( P<0.001). Other basic profiles of two groups were not statistically different. The median follow-up period was 32 months in lymphatic leakage group and 30.6 months in lymphatic non-leakage group. No significant inter-group difference existed in cumulative survival rate, vascular complications, bile leakage, acute cell rejection or intestinal obstruction. The area-under-curve (AUC) of ascites to serum triglyceride (TG) ratio for predicting lymphatic leakage was 0.741, optimal cut-off value 0.54, sensitivity 59.2% and specificity 80.1%. Conclusions:Lymphatic leakage is a common complication after liver transplantation in children. With no significant correlation with the morbidity or mortality, it prolongs postoperative hospital stay. The ratio of ascites to serum TG may be utilized as an effective reference index for diagnosing lymphatic leakage. And lymphatic leakage can be improved by taking a low-fat diet.

OBJECTIVE: To investigate the effect of hypertonic glucose injection on patients with chylous leakage after neck dissection.METHODS: The clinical data of 9 patients with postoperative chylous fistula after the lymph node dissection of thyroid cancer from February 2017 to December 2018 in the Department of Thyroid Surgery,the First Affiliated Hospital of Zhengzhou University were collected and analyzed.RESULTS: As for 9 patients with intractable chylous fistula,8 patients were finally cured and had the drainage tube removed.Three patients decreased significantly by over 50% on next day after hypertonic glucose injection.Four patients decreased significantly by over 50% on next two daysafter hypertonic glucose injection.One patient had to have another one operation to cure chylous fistula.CONCLUSION: In patients with chylous fistula after thyroid cancer surgery,local injection of hypertonic glucose seems to be more effective in shortening time of drainage tube remining,which would promote wound healing and release pains.
