Delayed gastric emptying after distal gastrectomy for gastric cancer

Gastric surgery may potentiate delayed gastric emptying. The aims of the study were to determine the frequency and causes of delayed gastric emptying in patients who had undergone distal gastrectomy for gastric carcinoma and to assess which factors predispose to its development.

209 patients, who had undergone gastrectomy, were evaluated.

Delayed gastric emptying occurred in 4.3% of patients receiving a Billroth-I, and 15.5% of patients receiving a Roux-Y reconstruction (p = 0.01). The patients who had these consecutive symptoms following Roux-Y operation were all clinically diagnosed as having Roux stasis syndrome. The delayed gastric emptying after Roux-Y operation was more frequent in patients receiving extensive lymph node dissection than those receiving conventional dissection (p<0.05). The symptoms spontaneously subsided, and postoperative body weight loss was not significant.

In spite of the strong association between delayed gastric emptying and the Roux-Y procedure, it enables a relatively early return to oral intake.
