Lymph Node Dissection by Laparoscopic Surgery in Patients Underwent Eight Colon Cancer Treatment

摘要

Aim To evaluate the feasibility, safety, and properties of dissected lymph nodes from the specimen of laparoscopic right hemicolectomy for colon carcinoma. Materials and method To perform a cross-sectional study of 80 right colon carcinoma patients who underwent laparoscopic right hemicolectomy at K Hospital of Hanoi Medical University and Can Tho Oncology Hospital from June 2012 to June 2016. Results and discussion There were 36 male and 44 female patients. Age ranges from 20-87-year-old, the average age was 54.8 ± 1.7. 15 patients had a history of previous operations. The mean size of tumors was 4.9 ± 0.2 cm (1.5-6 cm). A total of 992 lymph nodes were harvested, the mean number of nodes dissection for each patient was 12.4 mm ±2.8 (6-43 mm). The number of nodes dissection whose size from 0.5 to 1 cm were 589 (59.4%). Majority of lymph node's location was closed to the tumor edge and along arteries: ileocolic, right and middle colic arteries (80.1%). Metastatic rate of lymph nodes was moderate (40%). Conclusion Within the limit of this study, lymphadenec-tomy in Laparoscopic surgery for right colon carcinoma was the feasible and safe procedure. It conforms to the oncological principles. Characteristic properties of dissected lymph nodes from the specimen revealed mean of nodes dissection for each patient were 12.4 mm; a majority of node's locations were closed to the tumor edge and along the ileocolic, right colic and middle colic arteries. Metastatic rate of lymph nodes was moderate (40%).
