Meta analysis on the necessity for indwelling gastrointestinal decompression after gastrectomy / 中华普通外科杂志

ABSTRACT

Objective To evaluate the necessity of indwelling gastrointestinal decompression after gastrectomy. Methods Eight publications on the necessity of gastrointestinal decompression after gastrecomy were colleted, data on recovery time of gastrointestinal function and hospital stay, complications,and motality were Meta-analyzed using fixed effect model and random effect model. Results Eight randomized trails including 975 patients were qualified and included in this study. The differences in time to oral intake ( WMD =0. 61, 95% CI 0. 17 - 1.05, P ＜ 0. 05 ) and hospital stay ( WMD = 1.20, 95% CI0. 05 -2. 36, P ＜ 0. 05 ) between the decompression group and non-decompression group were statistically significant, but the difference in time to flatus (WMD = 0. 31,95% CI -0. 07- 0. 69, P ＞ 0. 05 ) was not significant. There were no significant differences in complications such as nausea and vomiting ( OR = 1.43,95% CI 0. 61 - 3.31, P ＞ 0. 05 ), pulmonary infection and atelectasis ( OR = 1.43, 95 % CI 0. 82 - 2. 49,P＞0.05), anastomotic leakage (OR = 1.17, 95%CI 0.54-2.49, P ＞0.05), abdominal abscess ( OR = 1.08, 95% CI 0. 50 - 2. 34, P ＞ 0. 05 ), wound dehiscence ( OR = 1.47, 95% CI 0. 43 - 4. 95,P ＞ 0. 05 ) between the two groups, except for fever ( OR = 1.76, 95% CI 1.11 - 2. 78, P ＜ 0. 05 ), which was found more frequent in decompression group than in non-decompression group. Conclusions Routine gastrointestinal decompression after gastrectomy was not conductive to the recovery of gastrointestinal function, and could not reduce the incidence of postoperative complications. Postoperative GI decompression increased fever incidence rate and prolonged hospital stay.
