Abstract: Objective To evaluate the effect on gastroesophageal reflux and gastric emptying in the different route of gastroesophageal anastomosis objectively after esophagectomy for patients with midesophageal carcinoma. Methods Forty patients with midesophageal carcinoma were randomly divided into two groups. Esophageal bed group (n=20): the gastroesophageal anastomosis were performed while the stomach were pulled on through the esophageal bed after esophagectomy; endothoracic group (n=20): gastroesophageal anastomosis were performed while the stomach were pulled on in the thoracic cavity. Ten persons had no disease of digestive system and healthy volunteers were recruited as normal control group. 24-hour esophageal pH monitoring and radioisotope gastric emptying checkup were carried out in all experimental subjects 3 months after operation, so as to observe the changes of gastroesophageal reflux and gastric emptying. Results All of the patients’s operation were success. And no anastomotic leakage and no anastomotic stenosis. Three months after operation, the patients in both operation groups were with different level of reflux. DeMeester total appraise score, the times of regurgitation of gastric juice in 24h, gt;5 min reflux frequency, the longest time of keep reflux, pHlt;4.00 total time and pHlt;4.00 of total time percent, these targets in both operation groups were higher than those in control group (Plt;0.01) DeMeester total appraise score, the times of regurgitation of gastric juice in 24 hours, the longest time of keeping reflux, pHlt;4.00 of total time and pHlt;4.00 of total time percent in esophageal bed group were lower than those in endothoracic group(Plt;0.01). The recent period of gastric emptying percentage (GE) in both operative groups were lower than that in normal control group. GE in esophageal bed group experimental meal in the stomach after entering the 30,60,90,120,180 and 240 min were higher than those in endothoracic group. Conclusion After the operation of esophagogastric anastomosis through esophageal bed in upper aortic site,gastroesophageal reflux and delayed gastric emptying exist objectively, However, the technique is superior to the traditional technique to reduce the extent of gastroesophageal reflux and delayed gastric emptying, its mechanism might be the result of mechanical factors.
Upper gastrointestinal tract cancers originating in the esophagus or esophagogastric junction constitute a major global health problem. On February 28, 2023, National Comprehensive Cancer Network (NCCN) released the clinical practice guidelines for esophageal and esophagogastric junction cancer (version 1.2023). This article will interpret the main updates related to the treatment and follow-up in this version compared to the version 5.2022, in order to provide the Chinese clinicians a better basis and reference for the diagnosis and treatment of the diseases.
ObjectiveTo investigate the role of GOLPH3 in esophageal squamous cell carcinoma (ESCC). MethodsWound healing assays, transwell invasion assays and 3D culture were carried out to analyze the cell migration and invasion ability of GOLPH3 overexpression and knockdown KYSE-140 cells. The relationship between GOLPH3 expression and CYR61, CD44 and Snail mRNA expression was further examined through qRT-PCR, to identify the mechanisms involved. ResultsGOLPH3-promoted ESCC cell migration and invasion. CYR61, CD44 and Snail mRNA expression levels were correlated with GOLPH3 protein expression level. ConclusionGOLPH3 overexpression promotes ESCC metastasis through epithelial-mesenchymal transition (EMT), and plays an oncogenesis role in ESCC.
Abstract: Objective To investigate the expression of inhibitor of apoptosis gene Livin and its relationship with expression of P53,Bcl-2 in esophageal carcinoma tissues. Methods The expression of Livin messenger ribonucleic acid (mRNA) in 36 esophageal carcinoma tissues and 18 paracancerous tissues were measured by reverse transcriptionpolymerase chain reaction (RT-PCR) combined with silver staining technique. The expression of Livin, P53 and Bcl-2 proteins were detected by immunohistochemical method (streptavidin-peroxidase). Results RT-PCR results: Livin mRNA positive expression of esophageal carcinoma tissues was more evident than that of paracancerous tissues, the expression of both variants was simultaneous basically. Immunohistochemical results: the Livin protein positive expression rate of esophageal carcinoma tissues was higher evidently than that of paracancerous tissues(Plt;0.01). Livin protein positive expression rate of external coat of esophagus invaded by carcinoma was higher than that of tunica muscularis esophagi invaded by carcinoma(Plt;0.05); Livin protein positive expression rate of lymph node metastasis was higher than that of normal lymph node (Plt;0.05). The expression of Livin protein was not related to the expression of P53 protein（χ2=1.00,P=0.505）,but it was positively related to the expression of Bcl-2 protein（χ2=10.60，P=0.003）. Conclusion Aberrant expression of Livin may be a new target for diagnosis and gene treatment of esophageal carcinoma.The aberrant expression of Livinand apoptosis related gene Bcl-2 may play synergetic roles in process of carcinogenesis of esophageal carcinoma.
ObjectiveTo investigate the predictive value of prognostic nutritional index (PNI) in complications after thoracoscopy-assisted radical resection of esophageal cancer.MethodsWe collected the clinical data of patients who underwent thoracoscopy-assisted esophagectomy in the First Affiliated Hospital of Xinjiang Medical University from January 2015 to June 2020. The predictive value of PNI for postoperative complications was evaluated by establishing receiver operating characteristic (ROC) curve and the optimal cut-off point was determined. The patients were divided into a high PNI group and a low PNI group according to the cut-off point. The differences of baseline data and perioperative complications-related indicators between the two groups were compared and analyzed. Univariate and multivariate analyses were used to investigate the influence of PNI and other related indexes on postoperative complications.ResultsA total of 116 patients were enrolled in this study, including 75 males and 41 females, aged 65 (58-69) years. The area under ROC curve was 0.647, and the optimal cut-off point was 51.9. According to the cut-off point, there were 45 patients in the high PNI group and 71 patients in the low PNI group. The overall complication rate (χ2=10.437, P=0.001) and the incidence of postoperative pulmonary infection (χ2=10.811, P=0.001) were statistically different between the two groups. The results of univariate analysis showed that the duration of ventilator use (Z=–3.136, P=0.002), serum albumin value (t=2.961, P=0.004), and PNI value (χ2=10.437, P=0.001) were the possible risk factors for postoperative complications after thoracoscopy-assisted esophagectomy. The results of multivariate analysis suggested that the duration of ventilator use (OR=1.015, P=0.002) and the history of drinking (OR=5.231, P=0.013) were independent risk factors for postoperative complications, and high PNI was the protective factor for postoperative complications (OR=0.243, P=0.047).ConclusionPNI index has a certain value in predicting postoperative complications, which can quantify the preoperative nutritional and immune status of patients. Drinking history and duration of ventilator use are independent risk factors for postoperative complications of thoracoscopy-assisted esophagectomy, and high PNI is a protective factor for postoperative complications.
ObjectiveTo evaluate the effect on complication after esophagectomy by comparing the different methods of anastomosis (cervical versus thoracic anastomosis). MethodsWe searched the following databases including PubMed, EMbase, The Cochrane Library, Web of Science, CBM, CNKI, VIP and Wanfang database to identify randomized controlled trials (RCTs) of cervical versus thoracic anastomosis for esophagectomy patients from establishment of each database to October 30, 2014. Quality of the included RCT was evaluated. Meta-analysis was conducted by using RevMan 5.2 software. ResultsWe finally identified 4 RCTs involving 267 patients. In terms of the postoperative complication, the incidence of anastomotic leakage (RR=3.83, 95%CI 1.70 to 8.63, P=0.001) with cervical anastomosis was significantly higher than that of the patients with thoracic anastomosis. However, there was no statistical difference in incidence of anastomotic stricture (RR=1.04, 95%CI 0.62 to 1.76, P=0.87), pulmonary complication (RR=0.73, 95%CI 0.27 to 1.91, P=0.52), and mortality (RR=0.89, 95%CI 0.40 to 1.97, P=0.77) between cervical and thoracic anastomosis. ConclusionCompared with thoracic anastomosis, the method of cervical anastomosis is associated with a higher incidence of anastomotic leakage. But there are many unclear factors about anastomotic stricture, pulmonary complication and mortality, further measurement should be taken.
The incidence of complications after radical resection of esophageal carcinoma is high up to about 20%-50%. The incidence of pneumonia, pleural effusion, tracheal intubation, anastomotic fistula and cardiac events is relatively high. Among them, pulmonary complications are the most common complications after esophageal cancer operation and cause the most perioperative deaths. Among the factors that influence the occurrence of postoperative complications of esophageal cancer, the amount of fluid infusion during and after the operation is closely related to the occurrence of postoperative complications. Moreover, in the environment of enhanced recovery after surgery (ERAS), it is more important to optimize the postoperative fluid management of esophageal cancer. Restricted fluid therapy plays a more and more important role in patients undergoing esophagectomy. This review integrated the relevant research results and discussed the advantages of the restricted fluid therapy compared with other fluid therapy, how to control the restricted infusion volume and infusion speed and how to monitor and evaluate the infusion process and the selection of infusion types, so as to provide reference for clinical practice test.
Esophageal cancer (EC) is the eighth dangerous cancer in the world. As the global population ages, the management of elderly patients with EC poses a challenge as they have many aging-associated diseases and physiological changes. In addition, the data on the tolerability of cancer treatment and the use of combined therapies in the patients to guide their treatment are limited. In this paper, we reviewed the literatures and discussed the effect of surgical resection and the potential complications of elderly patients. We reviewed the basic principles of combined therapy and the potential benefits of chemotherapy or chemoradiotherapy for patients and focused on the management of elderly patients with EC as well as the role of comprehensive assessment for aging to provide treatment options for elderly patients.
Two male patients (75 years and 51 years, respectively) suffered infection of novel coronavirus after minimally invasive surgery for esophageal squamous cell carcinoma in Sichuan Cancer Hospital since December 2022. Both patients developed severe hypoxemia after surgery, and were treated with advanced oxygen therapy, antiviral therapy, hormone shock therapy, antibiotic anti-infection and nutritional support. The two patients stayed in the intensive care unit for 6 days and 8 days respectively. They were transferred to the general ward for symptomatic treatment and were discharged successfully. Both patients required low-flow oxygen maintenance after discharge. On the 20th day of follow-up after discharge, patient 1 still needed low-flow oxygen, his oxygen saturation could be maintained above 97%, but intermittent deoxygenation could be performed for half an hour. Patient 2 was in good condition on 35 days after discharge.
Objective To analyze the risk factors affecting the occurrence of arrhythmia after esophageal cancer surgery, construct a risk prediction model, and explore its clinical value. Methods A retrospective analysis was conducted on the clinical data of patients who underwent radical esophagectomy for esophageal cancer in the Department of Thoracic Surgery at Anhui Provincial Hospital from 2020 to 2023. Univariate and multivariate analyses were used to screen potential factors influencing postoperative arrhythmia. A risk prediction model for postoperative arrhythmia was constructed, and a nomogram was drawn. The predictive performance of the model was then validated. Results A total of 601 esophageal cancer patients were randomly divided into a modeling group (421 patients) and a validation group (180 patients) at a 7 : 3 ratio. In the modeling group, patients were further categorized into an arrhythmia group (188 patients, 44.7%) and a non-arrhythmia group (233 patients, 55.3%) based on whether they developed postoperative arrhythmia. Among those with postoperative arrhythmia, 43 (10.2%) patients had atrial fibrillation (AF), 12 (2.9%) patients had atrial premature beats, 15 (3.6%) patients had sinus bradycardia, and 143 (34%) patients had sinus tachycardia. Some patients exhibited multiple arrhythmias, including 14 patients with AF combined with sinus tachycardia, 7 patients with AF combined with atrial premature beats, and 3 patients with AF combined with sinus bradycardia. Univariate analysis revealed that a history of hypertension, heart disease, pulmonary infection, acute respiratory distress syndrome, postoperative hypoxia, anastomotic leakage, and delirium were risk factors for postoperative arrhythmia in esophageal cancer patients (P<0.05). Multivariate logistic regression analysis showed that a history of heart disease, pulmonary infection, and postoperative hypoxia were independent risk factors for postoperative arrhythmia after esophageal cancer surgery (P<0.05). The area under the receiver operating characteristic curve (AUC) of the constructed risk prediction model for postoperative arrhythmia was 0.710 [95% CI (0.659, 0.760)], with a sensitivity of 0.617 and a specificity of 0.768. Conclusion A history of heart disease, pulmonary infection, and postoperative hypoxia are independent risk factors for postoperative arrhythmia after esophageal cancer surgery. The risk prediction model constructed in this study can effectively identify high-risk patients for postoperative arrhythmia, providing a basis for personalized interventions.
