Clinical analysis of 20 cases with postsurgical gastroparesis syndrome after radical subtotal gastrectomy

Objective To analyze the etiology, diagnostic methods, treatment of postoperative gastroparesis syndrome (PGS) after radical subtotal gastrectomy. Methods Clinical data of 501 cases with radical distal subtotal gastrectomy were collected and among them, 20 cases with PGS were enrolled. The incidence, occurrence time, recovery time, clinical manifestations and risk factors for PGS were analyzed. Results Preoperative gastric outlet occlusion, and Billroth Ⅱ gastrojejunostomy were high risk factors for PGS in above cases. Gastroscopy, X ray and scintigraphic measurement of gastric emptying were valuable in the diagnosis of gastroparesis. The gastric motility usually recovered within 6 weeks postoperatively. The effects of erythromycin on PGS were different individually. Conclusions A suitable irritation to remnant stomach during gastroscopy examination is helpful for the remission of PGS, and reoperation should be avoided.
