Abstract
Objective: To assess the results of laparoscopic surgery treatment for mild and low rectal cancer, stage II, III with preoperative short-course radiation.
Patients and method: 59 patients with resectable mild and low rectal cancer were treated with short- course radiation combined laparoscopic total mesorectal excision in 108 Military Central Hospital, from 08/2015 to 07/2017. The patient’s data were recorded: patient’s and tumor’s characteristics, acute and late toxicity of the preoperative radiotherapy, response after preoperative radiotherapy and result of the operation.
Result: Mean age was 58.4 ± 9.93 ( 34-81 years ). Low rectal cancer was 49.2% and mild rectal cancer was 50.8%. Diagnosis was base on MRI 3.0 tesla with stage II: 10.2% and stage III: 89.8%. Pathology staging with stage I: 20.3%, stage II: 54.2%, stage III: 25.5. 11.9% patients have Acute toxicity of the preoperative radiotherapy with grade 1 and 8.5% have Late toxicity of the preoperative radiotherapy grade 2.3. Mean operative time was 142 ± 35 Conversion rate to open surgery was 5.1%, intraoperative complication was 5.1%. Early complication was 28.9%. Mean postoperative time was 10.7±4,6 days. 77.9% patients have response from grade 1 to grade 4 after preoperative radiotherapy.
Conclusion: laparoscopic total mesorectal excision is favorable for mild, low rectal cancer stage II,III with preoperative short-course radiation.
