Abstract
background：Smoking is known to be the risk factor of the peri-operative complications. And pre-operative smoking cessation is suggested. In this study, we evaluated the influence of smoking on peri-operative com-plications in gastrectomy.
methods：The subjects were 103 patients who underwent gastrectomy in our institution between June 2010 and December 2012. Patients were classified into two groups based on their smoking histories, and we analyzed the peri-operative complications between the two groups. Furthermore, the group with smoking history was classified into two groups in having the duration of smoking cessation, then we studied the peri-operative complications.
results：In the 103 patients, 54 patients had smoking histories and, 49 patients didn’t have smoking histo-ry. The incidence of post-operative pulmonary complications among the group having smoking history is sig-nificantly high (p＜0.05).
In the group having smoking history, 31 patients had the duration of smoking cessation (57.4%). The inci-dence of post-operative pulmonary complications among the smokers is significantly high (p＜0.05).
conclusion：The risk of post-operative complications significantly decreases by the pre-operative smoking cessation. We think that it is important for surgeons to promote the instruction of pre-operative smoking cessation more positively, if the gastrectomy is decided.
