ObjectiveTo assess the efficacy of lymphadenectomy in different regions for esophageal squamous cell carcinomas located differently according to the lymph node grouping by Chinese expert consensus. MethodsThe medical records of 1 061 patients (886 males and 175 females with a median age of 60 (54, 65) years with esophageal cancer from March 2011 to December 2017 in our hospital were retrospectively analyzed. According to the pathological report, the lymph nodes were regrouped according to the Chinese lymph nodes grouping standard of esophageal cancer. The metastasis rate of each group of lymph nodes, the 5-year survival rate of metastatic patients and efficacy index (EI) were calculated. ResultsThe upper thoracic esophageal cancer mainly metastasized to the lymph nodes of C201-203 groups. The middle and lower thoracic tumors mainly metastasized to the lymph nodes of C205-207 groups. The lower thoracic tumor had a higher rate of metastasis to the abdominal lymph nodes. According to the metastasis rate, the mediastinal lymph nodes were divided into three regions: an upper mediastinum (C201-204), a middle mediastinum (C205-206), and a lower mediastinum (C207-209). The EIs of lymph nodes of C201-203 and C205-207 groups were higher. For patients with C201-207 groups metastasis, the 5-year survival rates ranged from 13.39% to 21.60%. For patients with positive lymph nodes in each region, tumors at different primary locations had no statistical difference in long-term survival (P>0.05). Patients with lymph nodes of C205 group in the upper thoracic tumors had lower EI and those in the middle and lower thoracic tumors had higher EIs. ConclusionThe effect of lymph node dissection in each area varies with the location of the tumor. No matter where the tumor is, it is necessary to dissect the upper mediastinal lymph nodes, especially the lymph nodes adjacent to the left and right recurrent laryngeal nerves. Group C205 should be classified into the lower mediastinal lymph nodes.
ObjectiveTo systematically evaluate the efficacy of tubular stomach and whole stomach reconstruction in the treatment of esophageal cancer.MethodsWe searched PubMed, Web of Science, The Cochrane Library, EMbase, CNKI, Wanfang Data, VIP and CBM databases to collect the randomized controlled trial (RCT) studies on the efficacy comparison between tubular stomach and total gastric reconstruction of esophagus in esophagectomy from their date of inception to May 2019. Then meta-analysis was performed by using RevMan 5.3 software.ResultsA total of Twenty-nine RCTs were included, and 3 012 patients were involved. The results of meta-analysis showed that the postoperative complications such as anastomotic fistula [RR=0.64, 95%CI (0.50, 0.83), P=0.000 6], anastomotic stenosis [RR=0.65, 95%CI (0.50, 0.86), P=0.002], thoracic gastric syndrome [RR=0.19, 95%CI (0.13, 0.27), P<0.001], reflux esophagitis [RR=0.23, 95%CI (0.19, 0.30), P<0.001], gastric emptying disorder [RR=0.39, 95%CI (0.27, 0.57), P<0.001] and pulmonary infection [RR=0.44, 95%CI (0.31, 0.62), P<0.001] were significantly reduced, and the postoperative quality of life score and satisfaction were higher at 6 months and 1 year in the tubular stomach group (P<0.05). In terms of intraoperative blood loss and postoperative hospital stay, they were better in the tubular stomach group than those in the whole stomach group (P<0.05). However, there was no statistically significant difference between the two groups in operation time, postoperative gastrointestinal decompression time, postoperative closed drainage time, postoperative 1-year, 2-year and 3-year survival rate, postoperative quality of life score at 3 weeks and 3 months, and postoperative life satisfaction at 3 weeks.ConclusionThe tubular stomach is more advantageous than the whole stomach in the reconstruction of esophagus after esophagectomy.
ObjectiveTo explore the application effects of hand-sewn layered anastomosis (HS) and circular stapled anastomosis (CS) in inflatable mediastinal mirror synchronous laparoscopic radical esophagectomy for esophageal cancer. MethodsPatients who underwent inflatable mediastinal mirror synchronous laparoscopic radical esophagectomy for esophageal cancer in Huaihe Hospital of Henan University from 2018 to 2019 were retrospectively included. Patients were divided into a HS group and a CS group according to the anastomosis methods, and propensity score matching was used to match patients at a ratio of 1:1. The baseline clinical characteristics, perioperative indicators, CD4+/CD8+ immune index comparison, pain, various lung function indicators, incidence of short-term and long-term postoperative complications, and quality of life were compared between the two groups. ResultsA total of 153 patients were included, including 108 males and 45 females, with an average age of (61.81±5.18) years. After propensity score matching, 70 patients were included in each group. Compared with the CS group, the operation time was longer in the HS group [(107.10±8.25) min vs. (97.65±6.85) min, P<0.001]; the CD4+/CD8+ level was lower in the HS group 1-3 days after surgery; the pain score was higher, and various lung function indicators (forced expiratory volume in the first second, forced vital capacity, and one-second rate) were lower in the HS group 1-7 days after surgery; within 6 months after surgery, the incidence of anastomosis-related complications (anastomotic stenosis, anastomotic fistula, and gastroesophageal reflux) was lower in the HS group; and the quality of life score was higher in the HS group from 14 days to 6 months after surgery (P<0.05). ConclusionHS can reduce the incidence of postoperative anastomotic fistula, anastomotic stenosis, and gastroesophageal reflux, and improve the short-term quality of life of patients, but it has a longer operation time, more intense short-term postoperative pain, and may affect the early recovery of lung function. HS and CS are complementary, and the appropriate surgical method should be chosen according to the individual situation of the patient to achieve the maximum clinical benefit.
ObjectiveTo explore the effect of preoperative glucocorticoid on systemic inflammatory indexes and pulmonary inflammation after radical esophagectomy.MethodsA total of 44 patients with esophageal cancer treated in the First Affiliated Hospital of Xiamen University from July 2019 to September 2020 were selected and randomly divided into an intervention group and an observation group by random number table. There were 22 patients in the intervention group, including 20 males and 2 females with an average age of 62.86±5.22 years and 22 patients in the observation group, including 19 males and 3 females with an average age of 63.00±6.19 years. Two groups were given thoracoscope-assisted incision via right chest, upper abdomen and left neck. The intervention group was given an intravenous infusion of methylprednisolone 500 mg before induction of anesthesia, and the observation group was given the same dose of normal saline. The second generation cephalosporins were routinely used to prevent infection in the two groups. The levels of interleukin-6 (IL-6) and C-reactive protein (CRP), lymphocyte and neutrophil count before operation and 1 day, 3 days and 5 days after operation were recorded and compared between the two groups. Utrecht Pneumonia Scoring System (UPSS) score 1 day after operation, the healing of the surgical incision and the anastomotic leakage within 2 weeks after the operation were evaluated.ResultsThe level of IL-6 in the intervention group was significantly lower than that in the observation group at 1 hour and 1 day after operation (both P<0.05). CRP showed significant difference between the two groups 2 days after operation (P=0.044). The white blood cell count in the intervention group was significantly less than that in the observation group 1 day and 3 days after operation (both P<0.05). There was no significant difference in lymphocyte or neutrophil count between the two groups 1 day after operation. There was no significant difference in the rate of non-grade A wound healing or the incidence of anastomotic leakage between the two groups within 2 weeks after operation. The pneumonia score of UPSS in the intervention group was lower than that in the observation group 1 day after operation (P=0.027).ConclusionThe use of glucocorticoid before radical esophagectomy can reduce the systemic inflammatory reaction and improve the short-term postoperative pulmonary inflammation. At the same time, no adverse effect on the healing of surgical incision and anastomotic stoma is found, which has certain safety.
ObjectiveTo explore the incidence and influencing factors of moderate-to-poor quality of recovery (QoR) in patients undergoing minimally invasive esophagectomy (MIE). MethodsA secondary analysis was conducted based on data from a randomized controlled study on the effects of different anesthesia methods on postoperative pulmonary complications after MIE. Patients who underwent elective MIE at West China Hospital of Sichuan University from May 2019 to December 2021 were included. The QoR-15 scale was used to assess the QoR 30 days postoperatively, and logistic regression analysis was performed to identify factors affecting moderate-to-poor QoR (defined as a QoR-15 score≤121). ResultsA total of 541 patients were included, including 426 males and 115 females, with an average age of (63.0±8.3) years. At 30 days postoperatively, the numbers of patients with excellent, good, moderate, and poor QoR were 101 (18.7%), 273 (50.5%), 147 (27.2%), and 20 (3.7%), respectively. Multivariate logistic regression analysis indicated that preoperative pain [OR=1.527, 95%CI (1.032, 2.258), P=0.034] and a nutrition risk screening-2002 score≥3 [OR=1.617, 95%CI (1.069, 2.447), P=0.023] were influencing factors for moderate-to-poor QoR 30 days postoperatively. ConclusionAbout 30.9% of patients undergoing MIE have a moderate-to-poor QoR 30 days postoperatively. Improving preoperative pain management and nutritional status may enhance postoperative QoR.
Objective To classify the postoperative complications (POCs) in patients receiving esophagectomy and find risk factors of different grades of complications. Methods We retrospectively analyzed the clinical data of 298 patients with esophageal cancer who underwent esophagectomy from January 2012 to August 2015 in our hospital. According to the postoperative complications, they were divided into two groups: the complication group (n=113) and the non-complication group (n=185). In the complications group, there were 86 males and 27 females with an average age of 61.42±7.81 years. There were 150 males and 35 females with an average age of 60.39±7.76 years in the non-complication group. The POCs were classified by Clavien-Dindo system. All possible factors influencing the occurrence of grade Ⅱ-Ⅴ POCs were analyzed. Univariate and multivariate analyses were used for seeking independent risk factors of POCs. Results The incidence of grade Ⅱ POCs was 29.87% (89/298), 5.37% (16/298) for grade Ⅲ and 2.68% (8/298) for grade Ⅳ and Ⅴ. The most common POC was lung infection with the incidence of 13.76%. Univariate and multivariate analyses showed the operation duration and the number of lymph node dissection were the independent risk factors of grade Ⅱ-Ⅴ POCs. Conclusion Postoperative lung infection is the major complication in patients receiving esophagectomy. The operation duration and the number of lymph node dissection are the independent risk factors of grade Ⅱ-Ⅴ POCs.
Esophageal carcinoma is one of the most common malignant tumor, a serious threat to human health. In the early and middle esophageal carcinoma patients, surgery is the only expected treatment to cure esophageal carcinoma. Traditional surgery of esophageal cancer needs thoracotomy and laparotomy, which has great trauma and high incidence of complications. So surgeons are looking for a minimally invasive surgical methods alternative to traditional esophagectomy. Video-mediastinoscopy is used to free middle and upper esophagus, as a minimally invasive surgical method, it is used in radical resection of esophageal cancer gradually. This article reviews the recent progress and the related research results in the application of mediastinoscopy in the radical resection of esophageal cancer. It is found that mediastinoscopy assisted the radical resection of esophageal cancer is a safe and feasible operation. It provides a feasible treatment option for early and middle stage esophageal cancer patients with pulmonary insufficiency who can not be resected by thoracoscopy.
