Abstract
Double tract anastomosis (DTA) is a recently revisited reconstruction method for preventing reflux esophagitis in laparoscopy-assisted proximal gastrectomy (LAPG). However, only few studies have shown the advantages of LAPG-DTA. Seventeen patients underwent LAPG-DTA compared to 17 patients undergoing laparoscopy-assisted total gastrectomy (LATG) matched with preoperative stage. Laboratory results, including hemoglobin, serum ferritin, serum iron and vitamin B12, were compared. Reflux esophagitis developed in two and one patient in the LAPG-DTA and LATG groups, respectively. In the laboratory analysis, fewer patients experienced decrease of serum ferritin below the low normal limit in the LAPG-DTA group. There was a significantly lower proportion of patients in the LAPG-DTA group whose vitamin B12 level decreased below the low normal limit. LAPG-DTA has the advantages of allowing absorption of iron and vitamin B12 without reflux esophagitis in proximal early gastric cancer compared to LATG.
