RESUMO
@#Objective To explore the causes of conversion to thoracotomy in patients with minimally invasive esophagectomy (MIE) in a surgical team, and to obtain a deeper understanding of the timing of conversion in MIE. Methods The clinical data of patients who underwent MIE between September 9, 2011 and February 12, 2022 by a single surgical team in the Department of Thoracic Surgery of the Fourth Hospital of Hebei Medical University were retrospectively analyzed. The main influencing factors and perioperative mortality of patients who converted to thoracotomy in this group were analyzed. Results In the cohort of 791 consecutive patients with MIE, there were 520 males and 271 females, including 29 patients of multiple esophageal cancer, 156 patients of upper thoracic cancer, 524 patients of middle thoracic cancer, and 82 patients of lower thoracic cancer. And 46 patients were converted to thoracotomy for different causes. The main causes for thoracotomy were advanced stage tumor (26 patients), anesthesia-related factors (5 patients), extensive thoracic adhesions (6 patients), and accidental injury of important structures (8 patients). There was a statistical difference in the distribution of tumor locations between patients who converted to thoracotomy and the MIE patients (P<0.05). The proportion of multiple and upper thoracic cancer in patients who converted to thoracotomy was higher than that in the MIE patients, while the proportion of lower thoracic cancer was lower than that in the MIE patients. The perioperative mortality of the thoracotomy patients was not significantly different from that of the MIE patients (P=1.000). Conclusion In MIE, advanced-stage tumor, anesthesia-related factors,extensive thoracic adhesions, and accidental injury of important structures are the main causes of conversion to thoracotomy. The rate varies at different tumor locations. Intraoperative conversion to thoracotomy does not affect the perioperative mortality of MIE.
RESUMO
BACKGROUND@#Video assisted thoracic surgery (VATS) is the main surgical method for lung cancer. The aim of this study was to analyze the reasons for conversion to thoracotomy in 83 cases among 1,350 consecutive cases who underwent video-assisted thoracic surgery (VATS) lobectomy by a single surgical team, in order to achieve a deeper understanding of the rules and the opportunity for conversion to thoracotomy in VATS lobectomy under normal conditions.@*METHODS@#The clinical data of 1,350 patients who underwent VATS lobectomy between September 21, 2009 and June 1, 2020, by a single surgical team in the Fifth Department of Thoracic Surgery of the Fourth Hospital of Hebei Medical University were retrospectively analyzed. There were 773 males and 577 females, aged 8-87 years, with a median age of 61.3 years, including 83 cases of benign diseases, 38 cases of lung metastases, and 1,229 cases of primary lung cancer. The cases with stage I, II and IIIa were 676, 323 and 230, respectively. The cases of left upper, left lower, right upper, right middle, right lower, right middle and upper and right middle and lower lobectomy were 301 (22.30%), 231 (17.11%), 378 (28.00%), 119 (8.81%), 262 (19.41%), 16 (1.19%) and 43 (3.19%), respectively.@*RESULTS@#In the cohort of 1,350 consecutive patients with VATS lobectomy, 83 patients (6.15%) were converted to thoracotomy for different reasons. The conversion rate of benign lesions was significantly higher than that of malignant tumors (P<0.05). The conversion rate in stage IIIa was significantly higher than that in stage I and II (P<0.05). The conversion rate of combined lobectomy was significantly higher than that of single lobectomy (P=0.001). The conversion rate of left upper lobectomy was significantly higher than that of other single lobectomy (P<0.001). The conversion rate of right middle lobectomy was significantly lower than that of other single lobectomy (P=0.049). The main reasons for conversion were vascular injury (38.55%), lymph node interference (26.51%) and dense adhesion in thoracic cavity (16.87%). In the conversion group, the total operation time was (236.99±66.50) min and the total blood loss was (395.85±306.38) mL. The operation time in patients converted to thoracotomy due to lymph node interference was (322.50±22.68) min, which was significantly longer than that in the other groups (P<0.05). The intraoperative blood loss in patients converted to thoracotomy due to vascular injury was (560.94±361.84) mL, which was significantly higher than that in the other groups (P<0.05). With the increase in surgical experience, the number of vascular injuries gradually decreased at the early stage, mid-stage and late stage (P=0.045).@*CONCLUSIONS@#In VATS lobectomy, benign lung lesions and more advanced malignant tumors led to more surgical difficulties and higher conversion rate. The conversion rate was different in different lobectomy sites, with the highest in left upper lobectomy, and the lowest in right middle lobectomy. Vascular injury, lymph node interference and dense adhesion were the main reasons for conversion to thoracotomy, which led to prolonged operation time and increased blood loss. With the increasing number of surgical cases, the rate of conversion to thoracotomy in VATS lobectomy continues to decline, which may be mainly due to the more advanced treatment of pulmonary vessels.
RESUMO
Objective To analysis the short-term quality of life and clinical outcome of early enteral immunonutrition(EIN)used after operation in patients with totally endoscopic esophagectomy.Methods This randomized controlled trial enrolled 110 patients receiving totally endoscopic esophagectomy in department of thoracic surgery of the fourth hospital of Hebei medical university between May 2015 and November 2016.The patients were randomly divided into enteral immunonutrition group (EIN group,n =56) and parenteral nutrition group (PN group,n=54).The scale scores of quality of life,the time of first postoperative anal exhaust,the time of removal of drainage tube,the number of postoperative infections and the length of hospitalization were compared between the two groups before operation and after operation.Results (1) There were no significant differences in age,gender,education,marital status,tumor location,clinical stage,intraoperative bleeding between the two groups (P＞0.05).(2) There were no significant differences in the quality of life before operation (P＞0.05);All functional scale scores of EIN group were significantly higher than PN group (P＜0.05),while the symptom scale score were significantly lower than PN group(P＜0.05).(3) There were significant differences in the time of first postoperative anal exhaust,the time of removal of drainage tube,the number of postoperative pneumonia compliCations and the length ofhospitalization in the two groups (P＜ 0.05).There was no significant difference in the incidence of anastomotic fistula between the two groups(x2=0.621,P=0.431 4) The scale scores of quality of life (the overall health status as the representative) had a negatively linear relationship with the clinical outcome(P =0.000),the absolute value of correlation coefficient in EIN group was higher than that in PN group.The higher score of the quality of life,the shorter time of the postoperative anal exhaust,removal of drainage tube and the length of hospitalization.Conclusion Enteral immunonutrition can improve the quality of life,improve the prognosis and promote the rapid recovery of patients with totally endoscopic esophagectomy.
RESUMO
Objective To explore the dynamic changes of serum HMGB1, CEA and SCC as well as the value in the evaluation of prognosis of patients with esophageal squamous cell carcinoma resection. Methods The dynamic changes in serum levels of HMGB1, CEA and SCC were measured respectively in 100 patients preopera-tively as well as a month after esophagectomy. The relationships between the changes of serum tumor markers and the clinical efficacy were analyzed. Results The 5-years survival rate of the CEA, SCC and HMGB1 negative peo-ple before operation was significantly higher than that of the positive patients (P < 0.05). The 5-years survival rate of those patients with all three markers negative before operation was significantly higher than that of those patients with the three markers positive (P < 0.01). The Median Survive Time of the patients with the levels of all three markers decreased after operation was longer than those with the levels of all the three markers increased (χ2 =6.584, P=0.01). The Median Survive Time of the patients with levels of the three markers decreased by more than 50%was longer than those with the levels decreased by less than 50% (χ2=5.418, P = 0.02). Conclusions The dynamic and combined detections of serum HMGB1, CEA, SCC in patients with esophageal squamous cell carcino-ma resection can effectively evaluate the therapeutic effect and prognosis.
