Abstract
Billroth I or II reconstruction after distal gastrectomy often is associated with inflammation in the gastric remnant. We sought to determine which reconstructive procedure was most effective in preventing such remnant gastritis. Patients undergoing curative distal gastrectomy for cancer (n = 82) were classified as group A (Roux-en-Y, n = 22); group B (Billroth I, n = 40); or group C (Billroth II, n = 20). Interleukin (IL)-8 concentrations in gastric mucosa were measured 3 months after surgery. In the absence of Helicobacter pylori infection, IL-8 concentrations were 13, 56, and 87 pg/mg protein in groups A, B, and C, respectively (p < 0.05). In the presence of H. pylori infection, IL-8 concentrations were 61, 161, and 234 pg/mg protein in groups A, B, and C (p < 0.01). Roux-en-Y reconstruction is better able to prevent remnant gastritis than either the Billroth I or II procedure as judged from IL-8 concentrations in gastric remnant mucosa.
