Aims: Esophageal replacement by gastric tube is present the procedure of choice in surgical treatment of carcinoma of esophagus. We would like to present our experiences in esophageal replacement by gastric tube without pyloroplasty in the Gastrointestinal Surgical Division at Binh Dan Hospital. Results: During 22 years (1979-2000), we performed 80 cases of esophagoplasty by gastric tube without pyloroplasty for 3 females and 77 males. The patient mean age was 61 years old. There were 51 cases of cancer of middle 1/3, 27 cases of cancer of the lower 1/3 and 2 cases of cancer of the cardio with esophageal extension. We had 24 cases of total esophagectomy, 29 cases of blunt esophagestomy and 27 cases of esophageal reconstruction by gastric tube. In 53 cases, gastric tube was in posterior mediastinum and 27 cases in substernal position. There were 15 patients presented postoperative pneumonia, 8 cases of anastomotic leakage in the neck, 4 cases of pneumothorax, 1 case with splenic rupture, 1 case of jejunal perforation, 2 cases of leakage of abdominal esophageal stump. The mean hospital stay was 20 days. No gastric emptying trouble was noted in this study. The functional results were good in patients survived this operation. Conclusion: The vascularization of the stomach was very good. In our experiences, esophageal reconstruction by gastric tube foiling Akiyama technique without pyloroplasty was suitable for all cases of esophageal cancer.

Background: Esophageal cancer is a common disease at Digestive Surgery Department of Binh Dan hospital. Surgical treatment is still a main procedure. Objectives: Study on a less invasive surgical technique in esophagectomy with supported thoracoscopy to provide a new esophageal cancer treatment. Subjects and method: Application on a new technique via thoracoscopy to esophagectomy totally in 6 patients (1 female, 5 males), aged 60 years on average, treated in Digestive Surgery Department of Binh Dan hospital from March 2006 to June 2006. Results: The average surgical time was 260 minutes. There was no event during operation. Postoperative complications included: 1 patient had to stitch abdominal wall after operative 7 days, 3 patients with pneumonia after successful operation, 2 patients with right pneumothorax, having to put siphonage. There was one case of death without related to operative technique. Conclusion: Esophagectomy is major operation that can be conducted via open surgery or laparoscopic surgery. Although small case studies, researchers found that laparoscopic surgery is a feasible technique, can be performed safely if the surgeons having experience in open surgery and good skills on laparoscopic surgery. However, thoracoscopic esophagectomy can only be considered as a surgical method, without an alternative method to traditional open surgery.

Objectives: Online misinformation has reached unprecedented levels during the coronavirus disease 2019 (COVID-19) pandemic. This study analyzed the magnitude and sentiment dynamics of misinformation and unverified information about public health interventions during a COVID-19 outbreak in Da Nang, Vietnam, between July and September 2020. Methods: We analyzed user-generated online information about five public health interventions during the Da Nang outbreak. We compared the volume, source, sentiment polarity, and engagements of online posts before, during, and after the outbreak using negative binomial and logistic regression, and assessed the content validity of the 500 most influential posts. Results: Most of the 54,528 online posts included were generated during the outbreak (n = 46,035; 84.42%) and by online newspapers (n = 32,034; 58.75%). Among the 500 most influential posts, 316 (63.20%) contained genuine information, 10 (2.00%) contained misinformation, 152 (30.40%) were non-factual opinions, and 22 (4.40%) contained unverifiable information. All misinformation posts were made during the outbreak, mostly on social media, and were predominantly negative. Higher levels of engagement were observed for information that was unverifiable (incidence relative risk [IRR] = 2.83; 95% confidence interval [CI], 1.33–0.62), posted during the outbreak (before: IRR = 0.15; 95% CI, 0.07–0.35; after: IRR = 0.46; 95% CI, 0.34-0.63), and with negative sentiment (IRR = 1.84; 95% CI, 1.23–2.75). Negatively toned posts were more likely to be misinformation (odds ratio [OR] = 9.59; 95% CI, 1.20–76.70) or unverified (OR = 5.03; 95% CI, 1.66–15.24). Conclusions Misinformation and unverified information during the outbreak showed clustering, with social media being particularly affected. This indepth assessment demonstrates the value of analyzing online “infodemics” to inform public health responses.
