Objective To study the safety and feasibility of modified laparoscopic Dixon surgery for rectal cancer. Methods In the procedure of modified laparoscopic Dixon surgery, the rectum with tumor was pulled out and cut and colon-rectum anastomosis was performed through anus. The clinical data of patients with rectal cancer between modified laparoscopic Dixon surgery (laparoscopy group) and open Dixon surgery (open group) were compared and analysed prospectively. The clinical data included operative time, volume of bleeding, number of lymph node dissection, volume of abdominal drainage, time to bowel gas passage, hospital stay and relative complications, such as anastomotic leakage, ureteral injury, dysuria and fecal incontinence. Results Fifty-eight cases were selected in this study between September 2007 and July 2008, including 25 laparoscopic surgery in laparoscopy group and 33 open surgery in open group. Patient’s data on gender, age, distance between tumor and anus edge, tumor diameter, tumor pathologic type and Dukes stage were similar between two groups by statistic analysis (Pgt;0.05). All the operations were performed successfully. Two cases experienced anastomotic leakage in laparoscopy group, while 1 case experienced anastomotic leakage in open group. All these patients got recovered by conservative treatment at last. No other complications were experienced, such as ureteral injury, dysuria, fecal incontinence, and so on. There were no significant differences in term of operative time, volume of bleeding and number of lymph node dissection between two groups (Pgt;0.05). The volume of abdominal drainage was less while the time to bowel gas passage and hospital stay were shorter in laparoscopy group than those in open group (P＜0.05). Conclusion This study reveals that it is safe and feasible to perform modified laparoscopic Dixon surgery for rectal cancer, and it presents the character of minimal invasion.
Coronavirus disease 2019 (COVID-19) is highly contagious, and the route of transmission is dominated by respiratory droplets and contact transmission. At present, the disease prevention and control are difficult. In order to prevent and control COVID-19 and prevent its spread in the hospital, West China Hospital of Sichuan University has set up isolation wards in the center of infectious diseases. The work norms for isolation ward were formulated. This may help to strengthen the prevention and treatment of COVID-19, effectively control the epidemic situation, as well as protect the health and safety of the public and medical staff. This article introduces the specific settings, diagnosis and treatment specifications, and hospital infection prevention and control strategies of the isolation ward of West China Hospital of Sichuan University, shares the work experience of isolation wards, aims to provide a reference for other hospitals to effectively prevent the spread of COVID-19 in hospitals and curb the spread of COVID-19.
