Abstract
PURPOSE: This study compared the pros and cons of two post-distal gastrectomy (DG) reconstruction methods by comparing the patient quality of life and functional dynamics at one year postoperatively. METHODS: We compared functional outcomes between Billroth I following laparoscopic 1/2 DG (L-B1; n = 27) and Roux en Y following laparoscopic 4/5 DG (L-RY; n = 24), including laparoscopic total gastrectomy (L-TG; n = 25), at one year postoperatively. Clinical investigations were performed in each patient, and functional evaluations by the acetaminophen (AAP) absorption test and plasma gastrointestinal hormone measurements were performed in consenting patients in each group (L-B1: n = 10, L-RY: n = 10, L-TG: n = 5). RESULTS: Postoperative/preoperative body weight ratios were significantly higher in the L-B1 and L-RY groups, in descending order than the L-TG group, although the meal intake ratio was not significantly different between the L-B1 and L-RY groups. The incidence of remnant gastritis was significantly higher in the B1 than in the RY group. AAP levels, glucose and glucagon-like peptide 1 were significantly lower in the L-B1 than in the L-RY group. Active ghrelin levels (AGL) were similar between the L-B1 and L-RY groups. CONCLUSIONS: L-B1 maintains gradual intestinal absorption and physiological meal passage and prevents postoperative weight loss. L-RY results in maintenance of the postoperative meal intake via high AGL, equivalent to that in the L-B1 group.
