RESUMEN
Objective To explore the application and efficacy of laparoscopic radical operation for rectal cancer after preoperative short-time radiotherapy.Methods The clinical data of 108 patients with Dukes B and C rectal cancer were analyzed retrospectively.Thirty-five patients underwent laparoscopic radical operation after preoperative short-time radiotherapy,meanwhile 30 patients underwent laparoscopic radical operation,and 43 patients underwent open operation,both later groups without preoperative radiotherapy.Results There were not significant differences in preoperative general condition,tumor size and stage,pathological type,site of operation,and mode of operation between the 3 groups.But there was a higher rate of radical resection and sphincter preservation in the laparoscopic operation plus radiotherapy group than in the other groups(P
RESUMEN
Objective To evaluate the effect of self expandable nitinol mesh stent (SENMT) for advanced rectal cancer accompanied with obstruction. Methods Clinical data were retrospectively analysed on 12 patients with advanced rectal cancer accompanied with acute or chronic obstruction treated by the stent placement. Results SENMT was placed successfully in 10 patients including replacement in 2 patients because of the stent was migrated. The bowel movement recovered in all of the 10 patients. Ten patients were followed-up, 5 cases died within 56-720 days, and 5 others survived without intestinal obstruction for 6-15 months. The stent failed to be placed in other 2 patients. Conclusions SENMT may be useful in the management of terminal or high risk surgical patients for palliative purposes. Palliation management of stent placement combined with chemotherapy and immunotherapy might prolong the survival time of these patients.
