PURPOSE: To investigate the regularity and the influence factors of nasogastric decompression volume after esophagectomy.

METHODS: Consecutive 247 patients with esophageal cancer who underwent esophagectomy were retrospectively evaluated. The volume of postoperative nasogastric decompression was recorded and the regularity based on it was described. The Single and multiple factors regression analysis were used to find out relative factors of the nasogastric decompression volume among the patients without postoperative complication. Gender, age, height, weight, tabacco or alcohol exposure, location of the tumor, histological type, pathological staging, operation time, surgical procedures, anastomotic position and gastric conduit reconstruction were considered as the independent variable.

RESULTS: In trend analysis, the curve estimation revealed a quadratic trend in the relationship between nasogastric decompression volume and postoperative days (R-square=0.890, P=0.004). The volume of postoperative nasogastric decompression was described by Daily drainage (ml) =82.215+69.620×days-6.604×days2. The results of multiple linear stepwise regression analysis showed that gastric conduit reconstruction (β=0.410, P=0.000), smoking (β=−0.231, P=0.000), age (β=−0.193, P=0.001) and histological type of the tumor (β=−0.169, P=0.006) were significantly related to the volume of nasogastric decompression. The Average drainage in five days after surgery=262.287+132.873×X1-72.160×X2-27.904×X3-36.368×X4 (X1=gastric conduit reconstruction, X2=smoking, X3=histological type, X4=age)

CONCLUSIONS: It is found that the volume of postoperative nasogastric decompression presents a quadratic trend based on the days after esophagectomy. Gastric conduit reconstruction, smoking history, age and histological type were independent factors affecting on the volume of postoperative nasogastric decompression. Also, the volume of nasogastric decompression has validity and application value for predicting postoperative complications.

CLINICAL IMPLICATIONS: This study can provide reference information to Fast-track surgery.
