Comparison on the Efficacy of Double Tract Gastric Interposition Reconstruction Versus Jejunal Interposition Reconstruction After Proximal Gastrectomy.

BACKGROUND This study aimed to compare the efficacy of antrum-preserving double tract gastric interposition reconstruction (ADGR) versus antrum-preserving double tract jejunal interposition reconstruction (ADJR) after proximal gastrectomy (PG). MATERIAL AND METHODS In a retrospective study, 62 cases of proximal gastric cancer undergoing proximal gastrectomy were divided into an ADJR group (n=32) and an ADGR group (n=30) according to reconstruction methods. Perioperative outcomes and postoperative complications were compared between the 2 groups, and the changes in hemoglobin (Hb), total protein (TP), body weight, and quality of life (QOL) were observed at 1, 3, 6, and 12 months postoperatively. Endoscopy was given at 12 months postoperatively for assessing reflux esophagitis and residual food. RESULTS Differences were indistinct in the 2 groups regarding the operation time, intraoperative blood loss, postoperative length of stay (LOS), first flatus time, and postoperative complications (P>0.05). At 1, 3, 6, and 12 months after operation, no evident differences were shown between the 2 groups regarding weight loss and Visick scores (P>0.05). Compared with the ADJR group, the Hb level at 6 and 12 months after operation and TP level at 12 months after operation were increased markedly in the ADGR group (P<0.05). No apparent difference was detected between the 2 groups in reflux esophagitis (P=0.467). The incidence of residual food in the ADGR group was significantly lower than that in the ADJR group (6.67% versus 31.25%, P=0.014). CONCLUSIONS ADGR was superior to ADJR in improving nutritional status and preventing residual food of patients with proximal gastric cancer after proximal gastrectomy.
