A pilot study comparing jejunal pouch and jejunal interposition reconstruction after proximal gastrectomy.

摘要

BACKGROUND/AIMS: The incidence of proximal gastric cancer is increasing, so proximal gastrectomies are often performed to preserve gastric function, but the optimal reconstruction method after surgery remains controversial. We therefore conducted a prospective pilot study comparing reconstructions using jejunal pouch interposition or jejunal interposition. METHODS: Thirty-eight patients with early proximal gastric cancer were included in this study. Equal numbers of patients were randomly assigned for reconstruction using jejunal interposition (the IP group) or jejunal pouch interposition (the PO group). Postoperative morbidity and patient symptoms were compared between the 2 groups. RESULTS: Postoperative morbidity was significantly more frequent in the IP than the PO group (p = 0.036). Moreover, the incidence of gastrointestinal complaints was more frequent in the IP group until 6 months after surgery. By contrast, the caloric intake was more favorable in the PO group until 1 year post-surgery. CONCLUSION: Short-term and mid-term outcomes were more favorable following jejunal pouch interposition compared with jejunal interposition after proximal gastrectomy.
