BACKGROUND/AIMS: We compared functional outcomes between different types of reconstruction following open or laparoscopic 1/2- or 2/3-proximal gastrectomy for gastric cancer. METHODOLOGY: Resection and reconstruction were performed by one of the following 6 methods, depending on the depth of cancer invasion and the date of the procedure relative to introduction of laparoscopic proximal gastrectomy: open proximal 2/3-gastrectomy with jejunal interposition (2/3 PG-int, n=7), open proximal 1/2-gastrectomy with jejunal interposition (1/2 PG-int, n=5), laparoscopic proximal 1/2-gastrectomy followed by double tract reconstructions with small (3 cm) jejunogastrostomy (L1/2 PG-DT(S), n=19) and laparoscopic proximal 1/2-gastrectomy followed by double tract reconstructions with large (6 cm) jejunogastrostomy (L1/2PG-DT(L), n=10). Open total gastrectomy with jejunal interposition (TG, n=12) and laparoscopic total gastrectomy with Roux-en-Y reconstruction (LTG, n=14) represented control procedures. RESULTS: Comparison of postoperative/preoperative body weight ratios and food intake ratios revealed better preservation among patients with a larger remnant stomach and with easy flow of food into the remnant stomach (the 1/2PG-int and L1/2PG-DT(L) groups). CONCLUSIONS: Better functional outcomes were observed in patients with a large remnant stomach and with easy flow of food into the remnant stomach regardless of whether they underwent open or laparoscopic procedures.
