A new three-layer-funnel-shaped esophagogastric anastomosis for surgical treatment of esophageal carcinoma

Table 1 Evaluation of swallowing quality after operation (Group A, n = 58)

	No symptom of dysphagia	With symptom of dysphagia
		Solid Food	Semisolids	Liquids
Preoperation	4 (6.9%)	23 (39.7%)	26 (44.8%)	5 (8.6%)
Postoperation	50 (86.2%)	5 (8.6%)	2 (3.4%)	1 (1.7%)

Analysed by wilcoxon rank test (Wilcoxon W = 2142, P = 0.0001), swallowing quality of patients after operation increased significantly compared with that before operation.

^bThe pathological type of esophageal carcinoma was different as reported in the west from that in China (P = 0.001), but it was not the major factor that affected the methods and early outcomes of operation.

^cCompared the pathologic type of cancer treated by the new(Group A) and the conventional (Group B) methods. ND: No data available.
