Purpose: Surgical-site infection (SSI) surveillance in Japan is based on NNIS system. Disease distribution differs between the US and Japan, with gastric and biliary surgery conducted widely in Japan. We subdivided about gastric and biliary surgery, conducting multicenter SSI surveillance in the Kansai area of western Japan to determine the justification for this subdivision. Methods: SSI surveillance at 20 hospitals subdivided gastric surgery into distal gastrectomy, (GAST-D), proximal gastrectomy (GAST-P), total gastrectomy (GAST-T), gastric wedge resection (GAST-W) and other type of gastric surgery (GAST-O). Biliary surgery was subdivided into partial hepatectomy (BILI-H), choleducotomy or biliary bypass (BILI-B), partial or distal pancreatectomy (BILI-P), partial hepatectomy with biliary reconstruction (BILI-HB), pancreatoduodenectomy (BILI-BP) and pancreatoduodenectomy with partial hepatectomy (BILI-HBP). Results: SSI rate of gastric surgery was GAST-D 4.6% (6/131), GAST-P 33.3% (1/3), GAST-T 11.8% (6/51), GAST-W 0% (0/13) and GAST-O 0% (0/12), while that in biliary surgery was BILI-H 19.5% (17/87), BILI-B 25.7% (9/35), BILI-P 18.9% (2/11), BILI-HB 60.0% (6/10), BILI-BP 30.8% (12/39) and BILI-HBP 50% (1/2). Conclusions: Differences among surgical method in gastric and biliary surgery in SSI surveillance in Japan suggest the feasibility of subdividing gastic and biliary surgery.
