Abstract:
Objective To explore influence of thoracic duct ligation on lipid metabolism after esophagectomy. Methods Seventy-four patients with esophageal cancer received esophagectomy were divided into two groups by their thoracic duct ligation, 39 in ligation group and 35 in non-ligation group. All the patients were fed with nutrients through nasal-duodenal tube placed during operation from the 1 st day to the 8th day after surgery, and started taking liquid diet on the 6th day. Blood specimens were collected from the patients on the 1st day after admission, the 9th day, one month and three months after surgery,respectively for biochemical analysis,including determinations of total cholesterol(TC),triglyeeride(TG),high-density lipoprotein-cholesterol ( HDL-C) and low-density lipoprotein-cholesterol ( LDL-C) . Databetween the two groups were compared with statistical analysis. Results No significant difference in plasma levels of TC, TG and HDI.-C was found between the two groups at varied time points. Plasma level of LDL-C in the ligation group significantly decreased on the 9th day after surgery, as compared with that in the nonligation group ( P ＜ 0. 05), and went down to the lowest level one month after surgery. Conclusions Chylomicron was blocked to enter blood stream and production of LDL-C decreased by thoracic duct ligation,which affect lipid absorption and metabolism leading to poor early nutrition in patients with esophagealsurgery due to slower establishment of collateral circulation.
