RESUMO
AIM: To determine the evidence-based values of prophylactic drainage in gastric cancer surgery. METHODS: One hundred and eight patients, who underwent subtotal gastrectomy with D1 or D2 lymph node dissection for gastric cancer between January 2001 and December 2005, were divided into drain group or no-drain group. Surgical outcome and post-operative complications within four weeks were compared between the two groups. RESULTS: No significant differences were observed between the drain group and no-drain group in terms of operating time (171 +/- 42 min vs 156 +/- 39 min), number of post-operative days until passage of flatus (3.7 +/- 0.5 d vs 3.5 +/- 1.0 d), number of post-operative days until initiation of soft diet (4.9 +/- 0.7 d vs 4.8 +/- 0.8 d), length of post-operative hospital stay (9.3 +/- 2.2 d vs 8.4 +/- 2.4 d), mortality rate (5.4% vs 3.8%), and overall post-operative complication rate (21.4% vs 19.2%). CONCLUSION: Prophylactic drainage placement is not necessary after subtotal gastrectomy for gastric cancer since it does not offer additional benefits for the patients.
