Postoperative functioning of the remaining stomach after pyloric sphincter preserving gastrectomy.
Pyloric sphincter preserving gastrectomy (SPG) has been used in 120 cases and the results were compared with those obtained in 73 cases who underwent the Billroth-I operation (B-I). No significant differences were observed in postoperative complications or anastomotic dysfunction. SPG patients, however, showed a longer gastric emptying time than the B-I patients, whereas the B-I patients showed a markedly greater increase in duodenogastric reflux than the SPG patients.
