Objective To study the relationship between cleanliness of children′s hands and diminution of Ascaris lumbricoides infection. Methods Before the study all persons positive for ascaris eggs in the preliminary survey were treated with albendazole. Hand washing habit before meal and after defecation was kept in children of experimental group, but not in the control group. Kato thick smear stool examination was done once every two months for one year to compare the new infection rates in children without ascaris infection in the two groups, and the reinfection rates in the cured negative cases were also compared between them in half a month after chemotherapy. Results All the new infection rates as well as reinfection rates of each reexamination in the experimental group were significantly lower than that of the control group ( P

Surgery is an important method for the treatment of resectable esophageal cancer. With the continuous development of minimally invasive esophageal technology, video-assisted thoracoscopic esophagectomy (VATE) has demonstrated obvious advantages over conventional open surgery and has been widely accepted. However, there are still some esophageal cancer patients who cannot benefit from VATE. Inflatable video-assisted mediastinoscopic transhiatal esophagectomy(IVMTE) does not require one-lung ventilation, reduces postoperative complications, expands surgical indications, and brings surgical opportunities for patients with impaired lung function and thoracic lesions, which has become a new choice for the treatment of esophageal cancer. However, the limited field of surgical view and the tunneling surgical approach undoubtedly increase the difficulty of surgery, and how to clearly expose the anatomical structures and thoroughly dissect the lymph nodes has always been the key points and difficulties of surgery. The authors review relevant literatures to discuss the clinical progress and limitations of IVMTE.

Objective    To investigate the short-term postoperative pain between robot-assisted and thoracolaparoscopic McKeown esophagectomy for esophageal carcinoma. Methods    We prospectively analyzed clinical data of 77 patients with esophageal carcinoma in our hospital between September 2016 and February 2017. The patients were allocated into two groups including a robot group and a thoracolaparoscopic group. The patients underwent robot assisted McKeown esophagectomy in the robot group and thoracolaparoscopic McKeown esophagectomy in the thoracolaparoscopic group. There were 38 patients with 30 males and 8 females at average age of 60.80±6.20 years in the thoracolaparoscopic group, and 39 patients with 35 males and 4 females at average age of 60.90±7.20 years in the robot group. Results    There was no statistical difference between the two groups in terms of the postoperative usage of analgesic drugs. The patients in the robot group experienced less postoperative pain on postoperative day 1, 3, 5, 6 and 7 than the patients in the thoracolaparoscopic group. The mean value of visual analogue scale (VAS) on postoperative day 1, 3, 5, 6 and 7 for the robot group and the thoracolaparoscopic group was 3.20±1.10 versus 2.70±0.90 (P=0.002), 2.75±0.96 versus 2.40±0.98 (P=0.030), 2.68±1.08 versus 2.02±0.8 (P=0.005); 2.49±0.99 versus 1.81±0.88 (P=0.003), 2.27±0.83 versus 1.51±0.61 (P<0.001), respectively. Conclusion    Compared with the thoracolaparoscopic group, patients receiving robot assisted McKeown esophagectomy experience less postoperative short-term pain. However, the long-term postoperative pain for these patients needs to be further studied.

Objective:To investigate the epidemiological characteristics and current status of surgical management for esophageal cancer in China.Methods:A national database was setup through a network platform. The clinical data of esophageal cancer treated by surgery was collected from 70 major hospitals in China between January 2009 and December 2014.Results:Complete data of 8 181 cases of esophageal cancer patients who underwent surgery were recorded in the database and recruited in the analysis. Among them, 6 052 cases were male and 2 129 were female, the average age was 60.5 years.The epidemiological investigation results showed that 148 cases (1.8%) had history of psychological trauma, 7 527 cases (92.0%) were lower social economic status, 5 072 cases (62.0%) were short of fresh vegetables and fruits, 6 544 cases (80.0%) ate rough food frequently, 3 722 cases (45.5%) drank untreated water directly from lake or river or shallow well, 3 436 cases (42.0%) had a unhealthy eating habit, including habits of eating food fast (507 cases, 6.2%), eating hot food or drinking hot tea/soup (998 cases, 12.2%), eating fried food (1 939 cases, 23.7%), 4 410 cases (53.9%) had the habits of smoking cigarettes and 2 822 cases (34.5%) drank white wine frequently.The pathological results showed that 7 813 cases (95.5%) were squamous cell carcinoma, 267 cases were adenocarcinoma (3.3%), 25 cases were adenosquamous cell carcinoma (0.3%) and 50 cases were small cell carcinoma (0.6%). A total of 1 800 cases (22.0%) received preoperative neoadjuvant therapy due to locally advanced disease or difficulty of resection. The esophagectomies were performed through left thoracotomy approach in 5 870 cases (71.8%), through right chest approach in 2 215 cases (27.1%), and the remain 96 cases (1.2%) received surgery though other approaches.A total of 8 001 cases (97.8%) underwent radical resection, the other 180 cases (2.2%) received palliative resection. The 30-day postoperative mortality rate was 0.5%, the overall ≥ grade Ⅱ postoperative complication rate was 11.6% (951 cases). The 1-yr, 3-yr, and 5-yr overall actual survival rates were 82.6%, 61.6%, and 52.9%, respectively.Conclusions:The data analysis of the national database for esophageal cancer shows that bad eating habits or eating rough food without enough nutrients, lower social and economic status, drinking white wine and smoking cigarettes frequently may be correlated with tumorigenesis of esophageal cancer. However, strong evidences produced by prospective observation studies are needed. Overall, the long-term survival of esophageal cancer patients has been improved gradually due to the application of advanced surgical techniques and reasonable multimodality treatment.

Resection is one of the most important treatments for esophageal squamous cell carcinoma, and routine postoperative follow-up is an effective method for early detection and treatment of recurrent metastases, which can improve patients' quality of life and prognosis. This consensus aims to provide a reference for colleagues responsible for postoperative follow-up of esophageal squamous cell carcinoma patients in China, and further improve the standardization of the diagnosis and treatment of esophageal squamous cell carcinoma.
