Abstract
Objective: To evaluate the results of laparoscopic total mesorectal excision after preoperative short-course radiation for rectal cancer. Subject and method: 70 patients stage II, III, mild and low rectal cancer were treated with short-course radiation combined with laparoscopic total mesorectal excision in 108 Military Central Hospital, from August 2015 to February 2019. The patients’ data were recorded: Patient’s characteristics, short-term and long-term results. Result: Low anterior resection surgery was 74.3%, Abdominoperineal resection surgery was 25.7%. Ileostomy rate was 53.8%. Intraoperative complication was 5.7%, serious postoperative complication was 12.1%. Mean operative time was 134.1 ± 32.4 minutes. Mean postoperative time was 10.7 ± 4.6 days. Complete and nearly complete mesorectum were 63.6% and 36.4% respectively. Mean distal resection margin was 24.5 ± 13.6mm. Distal margin with negative was 98.0%. Circumferential resection margin with negative was 98.5%. Overall survival and disease-free survival were 26.7 ± 9.6 months and 25.2 ± 10.9 months respectively. Recurrence rate was 12.1%. Late toxicity of the preoperative radiotherapy common grade 3 was 12.9%. Conclusion: Laparoscopic total mesorectal excision for mild and low rectal cancer were treated with preoperative short-course radiation is safety, effect and provided oncological radicality. Overall survival and disease-free survival were 26.7 ± 9.6 months and 25.2 ± 10.9 months respectively. Recurrence rate was 12.1%.
