Objective To evaluate the security and outcomes of thoracolaparoscopic esophagectomy (TLE) versus open approach (OA) for thoracic esophageal squamous cell carcinoma. Methods From June 2014 to June 2015, 125 patients with thoracic esophageal squamous cell carcinoma underwent esophagectomy through McKeown approach, including TLE (a TLE group, 107 patients, 77 males and 30 females) and OA (an OA group, 18 patients, 13 males and 5 females). The data of operation and postoperative complications of the two groups were analyzed retrospectively. Results There was no statistical difference in the duration of operation and ICU stay and resected lymph nodes around laryngeal recurrent nerve between the TLE group and the OA group (333.58±72.84 min vs. 369.17±91.24 min, P=0.067; 2.84±1.44 d vs. 6.44±13.46 d, P=0.272; 4.71±3.87 vs. 3.89±3.97, P=0.408) . There was a statistical difference in blood loss, total resected lymph nodes and resected lymph nodes groups between TLE group and OA group (222.62±139.77 ml vs. 427.78±276.65, P=0.006; 19.62±9.61 vs. 14.61±8.07, P=0.038; 3.70±0.99 vs. 3.11±1.13, P=0.024). The rate of postoperative complications was 32.7% in the TLE group and 38.9% in the OA group (P=0.608). There was a statistical difference (P=0.011) in incidence of pulmonary infection (2.8% in the TLE group and 16.7% in the OA group). Incidences of complications, such as anastomotic leakage, cardiac complications, left-side hydrothorax, right-side pneumothorax, voice hoarse and incision infection, showed no statistical difference between two groups. Conclusion For patients with thoracic esophageal squamous cell carcinoma, TLE possesses advantages of more harvested lymph nodes, less blood loss and less pulmonary infection comparing with open approach, and is complied with the principles of security and oncological radicality of surgery.
ObjectivesTo compare the clinical efficacy of different surgical thoracic duct management on prevention of postoperative chylothorax and its impact on the outcome of the patients. MethodsWe searched the electronic databases including PubMed, The Cochrane Library (Issue 4, 2016), Web of Science, CBM, CNKI, VIP and WanFang Data to collect randomized controlled trials (RCTs), cohort studies and case-control studies related to the comparison of different surgical thoracic duct management during esophagectomy on prevention of postoperative chylothorax from inception to May 2016. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then RevMan 5.2 software was used for meta-analysis. ResultsTwenty-three trials were included, involving four RCTs, four cohort studies and 15 case-control studies. The results of meta-analysis indicated:(1) Prophylactic thoracic duct ligation group had lower incidence of postoperative chylothorax compared with non thoracoic duct ligation group (RCT:OR=0.20, 95%CI 0.09 to 0.47, P=0.000 02; Co/CC:OR=0.20, 95%CI 0.14 to 0.28, P<0.000 01); (2) There were no significant differences between the two groups in the respect of mortality, morbidity and the 2-year, 3-year, 5-year survival rates (all P values >0.05); (3) Prophylactic thoracic duct ligation could reduce the reoperation rate of chylothorax complicating esophageal cancer patients (RCT:OR=0.17, 95%CI 0.10 to 0.28, P<0.000 01; Co/CC:OR=0.18, 95%CI to 0.11 to 0.32, P<0.000 01), and increase the cure rate of expectant treatment on them (OR=0.25, 95%CI 0.11 to 0.56, P=0.000 8); (4) En bloc thoracic duct ligation group had a lower incidence of postoperative chylothorax compared with single thoracic duct ligation group (OR=3.67, 95%CI 1.43 to 9.43, P=0.007). ConclusionProphylactic thoracic duct ligation during esophagectomy could effectively reduce the incidence of postoperative chylothorax and is good for reducing the reoperation rate of chylothorax complicating esophageal cancer patients. En bloc thoracic duct ligation has a better efficacy on prevention of postoperative chylothorax compared with single thoracic duct ligation.
With the widespread application of minimally invasive esophagectomy, inflatable video-assisted mediastinoscopic transhiatal esophagectomy (IVMTE) has gradually become one of the alternative surgical methods for transthoracic esophagectomy due to less trama, fewer perioperative complications and better short-term efficacy. However, there is no uniform standard for surgical methods and lymph node dissection in medical centers that perform IVMTE, which affects the standardization and further promotion of IVMTE. Therefore, on the basis of fully consulting domestic and foreign literature, our team proposed an expert consensus focusing on IVMTE, in order to standardize the clinical practice, guarantee the quality of treatment and promote the development of IMVTE.

ObjectiveTo compare the clinical efficacy of cone-shaped gastric tube combined with cervical end-to-end stratified manual anastomosis and conventional tubular stomach combined with neck end-to-end mechanical side-to-side anastomosis in thoracoscopic and laparoscopic esophagectomy for esophageal cancer. MethodsThe clinical data of consecutive patients treated by thoracoscopic and laparoscopic esophagectomy for esophageal cancer in the Department of Cardiothoracic Surgery of the First People's Hospital of Neijiang from January 1, 2018 to March 25, 2021 were analyzed. The patients were divided into a cone-shaped gastric tube manual group (treated with cone-shaped gastric tube combined with cervical end-to-end stratified manual anastomosis) and a conventional tubular stomach mechanical group (treated with conventional tubular stomach+end-to-end mechanical side-to-side anastomosis). The anastomotic time, intraoperative blood loss, number of lymph node dissection, anastomotic fistula, anastomotic stenosis, anastomotic cost, sternogastric dilatation, gastroesophageal reflux symptoms, and postoperative complications were compared and analyzed between the two groups. ResultsA total of 161 patients were enrolled, including 112 males and 49 females aged 40-82 years. There were 80 patients in the cone-shaped gastric tube manual group, and 81 patients in the conventional tubular stomach mechanical group. There was no statistical difference in the intraoperative blood loss, number of lymph nodes dissected, hoarseness, pulmonary infection, arrhythmia, respiratory failure or chylothorax between the two groups (P>0.05). The anastomosis time of the cone-shaped gastric tube manual group was longer than that of the conventional tubular stomach mechanical group (28.35±3.20 min vs. 14.30±1.26 min, P<0.001), but the anastomotic cost and incidence of thoracogastric dilatation in the cone-shaped gastric tube manual group were significantly lower than those of the conventional tubular stomach mechanical group [948.48±70.55 yuan vs. 4 978.76±650.29 yuan, P<0.001; 3 (3.8%) vs. 14 (17.3%), P=0.005]. The incidences of anastomotic fistula and anastomotic stenosis in the cone-shaped gastric tube manual group were lower than those in the conventional tubular gastric mechanical group, but the differences were not statistically significant (P>0.05). The gastroesophageal reflux scores in the cone-shaped gastric tube manual group were lower than those in the conventional tubular gastric mechanical group at 1 month, 3 months, 6 months and 1 year after the operation (P<0.05). Logistic regression analysis showed that digestive tract reconstruction method was the influencing factor for postoperative thoracogastric dilation, which was reduced in the cone-shaped gastric tube manual group. ConclusionCone-shaped gastric tube combined with cervical end-to-end stratified manual anastomosis can significantly reduce the incidence of thoracogastric dilatation after thoracoscopic and laparoscopic esophagectomy for esophageal cancer and save hospitalization costs, with mild gastroesophageal reflux symptoms, and it still has certain advantages in reducing postoperative anastomotic fistula and anastomotic stenosis, which is worthy of clinical promotion.
Objective To introduce a simple preoperative risk score for esophageal cancer (PRSEC) and its relationship with the prognosis of patients who underwent resection of esophageal carcinoma. Methods We retrospectively analyzed the clinical data of 498 patients receiving resection of esophageal carcinoma between 2005 and 2015 in our hospital. They were divided into three groups (PRSEC1, PRSEC2 and PRSEC3 groups) according to the results of PRSEC (revised cardiac risk index, model for end-stage liver disease score and pulmonary function test). Their overall survival (OS) and disease-free survival (DFS) were measured to find the relationship between the PRSEC and prognosis of patients. Results The mortality, morbidity, DFS and OS were correlative with the PRSEC. Therefore the PRSEC can be used to predict the short-term outcome. The patients with score 2 or 3 had higher risk of mortality and morbidity than those with score 1. In addition, the DFS and OS of patients with higher score were shorter (P<0.001). Conclusion The PRSEC is easy and efficient and can predict the morbidity, mortality, and long-term outcomes for the patients with resection of esophageal carcinoma.
