ObjectiveTo review the lymph node metastasis pattern and its dissection value among adenocarcinoma of the esophagogastric junction (AEG) patients, in order to assist suitable individualized lymph node dissection strategies for diverse AEG patients. MethodsThe reports about lymph node metastasis and the value of dissection of AEG worldwide in recent years were retrieved and summarized. ResultsThe sites with higher lymph node metastasis rate of AEG included No.1, No.2, No.3, No.7 lymph nodes, etc. and sites with higher lymph node metastasis rate often benefit from dissection. Lymph node metastasis was related to factors such as tumor size and location, and lymph node dissection at individual sites is still controversial. ConclusionThe lymph node dissection range of AEG is highly controversial, especially for Siewert type Ⅱ AEG, which still requires prospective multicenter studies to prove.
Objective To analyze the clinical characteristics of patients treated with esophagectomy following endoscopic submucosal dissection (ESD) for early stage esophageal cancer or precancerosis and the reasons for esophagectomy. Methods We retrospectively analyzed the clinical data of 57 patients who were treated with esophagectomy following ESD in West China Hospital and Shanxian Hygeia Hospital from January 2012 through October 2016. There were 42 males and 15 females at age of 65.4 (52–77) years. There were 15 patients of upper thoracic lesions, the middle thoracic lesions in 34 patients, and the lower thoracic lesions in 8 patients. Results The reasons for esophagectomy included 3 patients with residual tumor, 8 patients with local recurrence, 37 patients with esophageal stricture, and 9 patients with dysphagia, although the diameter was larger than 1.0 cm. The pathology after esophagectomy revealed that tumor was found in 16 patients, including 3 patients with residual tumor and 8 with recurrent tumor confirmed before esophagectomy, and 5 patients with new-found recurrent tumor. Conclusion In the treatment of early stage esophageal cancer or precancerosis, the major reasons for esophagectomy following ESD include esophageal stricture, abnormal esophageal dynamics, local residual or recurrence.
Objective To systematically review the prognostic significance of extranodal extension in gastric cancer, esophageal cancer and gastroesophageal junction cancer. Methods We searched EMbase, The Cochrane Library (Issue 9, 2016), PubMed, CBM, CNKI, VIP and WanFang Data databases from inception to August 2016, to collect cohort studies about the prognostic significance of extranodal extension. Two reviewers independently screened literature, extracted data and evaluated the risk of bias of included studies. Then, meta-analysis was performed by using RevMan 5.2 software. Results A total of 16 studies involving 9 445 participants were included. The results of meta-analysis showed that for gastric cancer patients, the overall survival (OS) (HR=1.71, 95%CI 1.49 to 2.00,P<0.000 01), disease free survival (DFS) (HR=1.39, 95%CI 1.12 to 1.73,P=0.003) and cancer specific survival (HR=1.52, 95%CI 1.18 to 1.96,P=0.001) in ENE(+) group were lower than ENE(–) group. For esophageal cancer and gastroesophageal junction cancer patients, the overall survival (OS) (HR=1.84, 95%CI 1.49 to 2.27,P<0.000 01), disease free survival (DFS) (HR=2.18, 95%CI 1.70 to 2.81,P<0.000 01) and cancer specific survival (HR=1.73, 95%CI 1.19 to 2.52,P=0.004) in ENE(+) group were lower than ENE(–) group. Conclusion Current evidence indicates that ENE(+) was correlated with a poor prognosis in gastric cancer, esophageal cancer and gastroesophageal junction cancer patients. Due to the quantity and quality limitations of included studies, more high quality cohort studies are needed to verify the above conclusions.
ObjectiveTo investigate the effect of jejunostomy combined with Ivor-Lewis or McKeown operation on the treatment of middle and lower esophageal cancer.MethodsThe clinical data of 127 patients with middle and lower esophageal cancer admitted to our hospital from June 2018 to October 2019 were retrospectively analyzed, including 89 males and 38 females, aged 62.82±8.65 years. The patients were divided into an Ivor-Lewis group (IL group, 72 patients) and a McKeown group (MK group, 55 patients) according to surgical methods. Patients in the IL group received jejunostomy combined with Ivor-Lewis operation, and patients in the MK group received jejunostomy combined with McKeown operation. The operation time, postoperative bedside electrical impedance tomography (EIT) parameters, postoperative inflammatory factor levels, postoperative complications and rehabilitation of the two groups were compared.ResultsThe operation time (262.65±49.78 min vs. 303.04±60.13 min), postoperative eating time (10.54±2.22 d vs. 11.47±2.49 d) and postoperative hospital stay (14.78±2.47 d vs.15.72±2.36 d) in the IL group were significantly shorter than those in the MK group (P<0.05). The blood loss (156.13±52.43 mL vs. 158.87±48.47 mL) and the number of lymph node dissection (29.47±8.88 vs. 30.17±9.80) in the IL group were less than those in the MK group, but the differences were not statistically significant (P>0.05). The repeated measurement analysis of variance showed that the time point could significantly affect tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and IL-8 levels (Ftime point=520.543, 272.379, 147.688, all P<0.05), but the surgical methods and the interactive effect of time point and surgical methods did not affect the levels of TNF-α, IL-6 and IL-8 (P>0.05). Postoperative bedside EIT image parameters were statistically different on the postoperative 1 d, 3 d, 5 d and 7 d between the two groups (P<0.05). Compared with the MK group, the incidences of recurrent laryngeal nerve injury, arrhythmia, pulmonary infection and atelectasis, anastomotic leakage, gastric wall necrosis and stump fistula, secondary thoracotomy and abdominal hemostasis, and intestinal obstruction were lower, but the differences were not statistically different (P>0.05). The recurrence rate of patients in the IL group within 6 months was lower than that in the MK group, but the difference was not statistically significant (8.33% vs. 9.09%, P>0.05).ConclusionJejunostomy combined with Ivor-Lewis or McKeown surgery have equivalent effects on patients with middle and lower esophageal cancer.
The informatization construction in medical field not only brings convenience to clinical doctors, but also creates huge data for clinical research. Taking the application of information technology in thoracic surgery as an example, we decide to talk about the establishment and application of esophageal cancer database based on standardized and structured electronic medical records. The aim, through the construction of database, is to improve clinical doctors’ management ability of esophageal cancer, to provide reference of the information construction to medical colleagues, and to promote the application of information in medicine.
ObjectiveTo compare the short- and long-term efficacy of surgery and endoscopy in the treatment of early esophageal cancer by a systematic review and meta-analysis.MethodsWe extracted data independently from The Cochrane Library, PubMed, EMbase, Web of Science for studies comparing surgery with endoscopy from 2010 to 2020. The primary outcomes including R0 resection rate, long-term overall survival (OS), disease-specific survival (DSS), major complications, recurrence, hospital stay and cost. Meta-analysis was performed using RevMan 5.3 and Engauge Digitizer was used to extract survival curves from relevant literature, and relevant data were calculated based on statistical methods. ResultsA total of 17 studies involving 3 705 patients were included. It was found that patients in the surgery group had a higher R0 resection rate compared with the endoscopic group (OR=0.13, 95%CI 0.07 to 0.27, P<0.001, I2=6%). The total complications rate of resection of esophageal cancer was higher than that of the endoscopic group (OR=0.28, 95%CI 0.16 to 0.50, P<0.001, I2=68%). The length of hospitalization in the endoscopic group was obviously shorter than that in the surgery group (MD=–8.28, 95%CI –12.44 to –4.13, P<0.001, I2=96%). The distant recurrence rate (OR=0.58, 95%CI 0.24 to 1.41, P=0.230, I2=0%) and the local recurrence rate after resection (OR=1.74, 95%CI 0.66 to 4.59, P=0.260, I2=40%) in the endoscopic group was similar to those of the surgery group. There was no significant difference in 5 year-OS rate between the two groups (HR=0.86, 95%CI 0.67 to 1.11, P=0.25, I2=0%), which was subdivided into two groups: adenocarcinoma (HR=0.55, 95%CI 0.15 to 2.05, P=0.37, I2=0%) and squamous cell carcinoma (HR=0.68, 95%CI 0.46 to 1.01, P=0.06, I2=0%), showing that there was no difference between the two subgroups. There was no significant difference in the DSS rate (HR=0.72, 95%CI 0.49 to 1.05, P=0.090, I2=0%) between the two groups. The cost of the surgery group was significantly higher than that of the endoscopic group (MD=–12.97, 95%CI –18.02 to –7.92, P<0.001, I2=93%).ConclusionThe evidence shows that endotherapy may be an effective treatment for early esophageal neoplasm when considering the long-term outcomes whether it is squamous or adenocarcinoma, even though it is not as effective as surgery in the short-term efficacy.
Surgery is a classic traditional method for the treatment of early-stage esophageal cancer, and it is also recognized as an effective first-choice method in the medical community. With the development of endoscopic technology, esophagus-preserving comprehensive treatment of esophageal cancer has almost the same or even better effects in some aspects in the treatment of early esophageal cancer than surgery. Many clinical guidelines have also recommended it as the first-choice treatment for early esophageal cancer. The room for surgical treatment of esophageal cancer has been further compressed. This article discusses the comprehensive treatment model of esophageal cancer from the perspective of thoracic surgery, aiming to find a new position of thoracic surgery in the treatment of esophageal cancer.
Objective To evaluate the effects of robot-assisted Ivor Lewis esophagectomy (RAILE) in surgical treatment of esophageal cancer. Methods We retrospectively analyzed the clinical data of 70 patients diagnosed with mid-lower esophageal cancer undergoing RAILE in the Department of Thoracic Surgery in Ruijin Hospital Affiliated to Shanghai Jiaotong University between May 2015 and April 2018. There were 54 males and 16 females at average age of 62.0±7.6 years. Forty patients underwent circular end-to-end stapled intrathoracic anastomosis and 30 had a double-layered, completely hand-sewn intrathoracic anastomosis. Results The mean operating time was 308.7±60.6 minutes. And blood loss was 190.0±95.1 ml. There were 2 patients who underwent conversion to thoracotomy. There was no in-hospital and 30-day mortality. Overall complications were observed in 24 patients (34.3%), of whom 6 patients (8.6%) had anastomotic leakage. The median length of hospitalization was 9.0 (interquartile range, IQR, 5.0) days. The mean tumor size was 3.2±1.5 cm, and R0 resection was achieved in all patients. The mean number of totally dissected lymph nodes was 19.3±8.7. Conclusion RAILE is safe and technically feasible with satisfactory perioperative outcomes.
Objective To investigate the application of enhanced recovery after surgery (ERAS) in da Vinci robotic McKeown surgery for esophageal cancer. Methods Clinical data of patients admitted to the First Hospital of Lanzhou University and undergoing da Vinci robotic McKeown surgery for esophageal cancer from 2017 to 2021 were retrospectively analyzed. According to the treatment, they were divided into two groups, a conventional group and an ERAS group. Patients in the conventional group were treated with the conventional perioperative treatment mode of thoracic surgery, and patients in the ERAS group were treated with accelerated rehabilitation surgical treatment mode. Relevant hospitalization indicators and postoperative complication rates were compared between the two groups. Results Finally 128 patients were collected, including 106 males and 22 females, with an average age of 61.91 years. There were 71 patients in the conventional group and 57 patients in the ERAS group. The postoperative pain index in the ERAS group was significantly lower than that in the conventional group (P<0.05), and the duration of postoperative analgesic pump used in the ERAS group was shorter than that in the conventional group (2.39±0.49 d vs. 3.13±0.63 d, P<0.001). There was no statistical difference in the incidence of postoperative related complications (gastroesophageal reflux, anastomotic stenosis, anastomotic fistula, arrhythmia, recurrent laryngeal nerve injury, chylothorax, anastomosis stomatitis or incisional infection) between the two groups (P>0.05), but the incidence of postoperative lung infection in the ERAS group was statistically lower (12.28% vs. 26.76%, P=0.043), and the volume of postoperative pleural effusion was statistically less compared with the conventional group (P<0.05). In the ERAS group, the surgery time (294.35±15.19 min vs. 322.79±59.09 min, P<0.001), postoperative exhaust time (1.44±0.39 d vs. 1.94±0.43 d, P<0.001), postoperative removal time of nasolasal tube (6.79±0.73 d vs. 8.21±0.86 d, P<0.001), hospital stay (19.88±3.36 d vs. 21.34±3.59 d, P=0.020), hospitalization costs (105 575.28±8 960.75 yuan vs. 137 894.64±19 518.60 yuan, P<0.001) were all lower or shorter than those of the conventional group. Postoperative activity was longer in the ERAS group than that in the conventional group (P<0.05), but there was no statistical difference in preoperative anesthesia time between the two groups (P=0.841). Conclusion The application of ERAS in da Vinci robotic McKeown surgery for esophageal cancer can effectively alleviate the physiological and psychological burden of patients, reduce the occurrence of postoperative related complications, effectively shorten the total hospital stay, save hospitalization costs, and reduce the economic burden of patients and society. Therefore, it can be promoted and applied in the clinic.
