Objective To investigate the effect of one stage arterialization of posterior tibial vein in treatment of peripheral arterial extensive occlusive disease. Methods Forty-six cases (56 limbs) of patients with peripheral arterial extensive occlusive disease were treated with one stage arterialization of posterior tibial vein. Results The symptom of pain disappeared right after one stage arterialization of posterior tibial vein in all patients . Skin temperature went up. The long-term results were satisfactory during the period of 3 months to 7 years follow-up, except two limbs were amputated and two limbs were reoperated with pedicle omental transplantation. Conclusion The technique of one stage arterialization of posterior tibial vein has advantages of one-stage procedure, various indications, little influence to venous return and rapid relief of ischemic symptoms.
Despite a wider application of robot to radical esophageal resection in recent years, the process of esophagogastrostomy is relatively complicated. Current commonly-applied clinical techniques in digestive tract reconstruction include end-to-end anastomosis, end-to-side anastomosis, and side-side anastomosis. The main methods are divided into manual and mechanical anastomosis. And the main instruments applied include circular stapler and linear stapler. Different technologies vary in advantages and restrictions and selecting the technique in esophageal operation depends on the situation of the tumor and the operator’s preference. The improved anastomosis techniques and the updated anastomosis instruments effectively lower the incidence of complications after esophagogastrostomy. However, there are still great difficulties in carrying out a safe and efficient reconstruction of the digestive tract during the operation. Scholars over the world have been working hard on it and have made modified various reconstruction techniques. Different technologies vary in advantages and restrictions and the choice of the technique depends on the situation of the tumor and the patient’s preference. There is no unified consensus on the choice of the technique. This paper introduces the research progress in robot’s assisted esophagogastrostomy from two aspects including the technique and method of anastomosis.
Objective To evaluate the effect of mediastinal drainage tube placed in the left thoracic cavity after partial resection of the mediastinum pleura in robot-assisted McKeown esophagectomy for esophageal carcinoma, and to compare it with the traditional method of mediastinal drainage tube placed in mediastinum. MethodsWe retrospectively analyzed clinical data of 96 patients who underwent robot-assisted McKeown esophagectomy for esophageal carcinoma by the surgeons in the same medical group in our department between July 2018 and March 2021. There were 78 males and 18 females, aged 52-79 years. Left mediastinum pleura around the carcinoma during operation was resected in all patients. Patients were divided into two groups according to the method of mediastinal drainage tube placement: a control group (placed in mediastinum) and an observation group (placed through the mediastinal pleura into the left thoracic cavity with several side ports distributed in the mediastinum). The incidence of left thoracentesis or catheterization after surgery, anastomotic fistula and anastomotic healing time, other complications such as pneumonia and postoperative pain score were also compared between the two groups. Results There was no statistical difference in baseline data or surgical parameters between the two groups. The percentage of patients in the observation group who needed re-thoracentesis or re-catheterization postoperatively due to massive pleural effusion in the left thoracic cavity was significantly lower than that in the control group (5.6% vs. 21.4%, P=0.020). The incidence of anastomotic leakage (3.7% vs. 7.1%, P=0.651) and the healing time of anastomosis (18.56±4.27 d vs. 24.33±5.48 d, P=0.304) were not statistically different between the two groups, and there was no statistical difference in other complications such as pulmonary infection. Moreover, the postoperative pain score was also similar between the two groups. Conclusion For patients whose mediastinal pleura is removed partially during robot-assisted McKeown esophagectomy for esophageal carcinoma, placing the drainage tube through the mediastinal pleura into the left thoracic cavity can reduce the risk of left-side thoracentesis or catheterization, which may promote the postoperative recovery of patients.
Objective To analyze influencing factors and construction of a nomogram predictive model for anastomotic leak after radical esophageal and gastroesophageal junction carcinoma. Methods The patients who underwent radical esophagectomy at Jinling Hospital affiliated to Nanjing University School of Medicine from January 2018 to June 2020 were selected. After screening for related variables using SPSS univariate and multivariate logistic regression analysis, the "nomogram" was used to predict the risk of anastomotic leak based on R language. The predicted effects were verified by the receiver operating characteristic (ROC) curves. Results A total of 468 patients with esophageal carcinoma were collected, including 354 (75.64%) males and 114 (24.35%) females with a mean age of 62.8±7.2 years. The tumor was mainly located in the middle or lower stage; 51 (10.90% ) patients had postoperative anastomotic leak. In univariate logistic regression analysis, age, BMI, tumor location, preoperative albumin, diabetes mellitus, anastomosis mode, anastomosis site, and CRP might be associated with anastomotic leak (P＜0.05). The above data suggested by multivariate logistic regression analysis illustrate that age, BMI, tumor location, diabetes mellitus, anastomosis mode, and CRP were independent risks of anastomotic leak (P＜0.05). The nomogram was constructed according to the results of multivariate logistic regression analysis. The area under the curve (AUC) of ROC curve was 0.803 showing that the actual observations agree well with the predicted results. In addition, the decision curve analysis concluded that the newly established nomogram was significant for clinical decision-making. Conclusion The predictive model of anastomotic leak after radical esophageal and gastroesophageal junction carcinoma has a good predictive effect and is critical for guiding clinical observation, early screening and prevention.
