BACKGROUND: This meta-analysis was designed to evaluate the necessity of indwelling gastrointestinal decompression after gastrectomy.

METHODS: Medline, Embase, and the Cochrane Library were searched. We identified randomized controlled trials that compared individuals with or without gastrointestinal decompression after gastrectomy, and a meta-analysis was performed on data regarding the recovery time of gastrointestinal function, length of hospital stay, complications, and mortality using fixed effect and random effect models.

RESULTS: Eight randomized controlled trials that had enrolled 975 patients were included in the present study. The difference in the interval to oral intake (weighted mean difference 0.56, 95% confidence interval [CI] 0.16-0.96, P = 0.006) between the decompression group and nondecompression group was significant, but no significant differences were found in the interval to flatus (weighted mean difference 0.24, 95% CI -0.13 to 0.61, P = 0.20) or length of hospital stay (weighted mean difference 1.04, 95% CI -0.05 to 2.14, P = 0.06). Additionally, no significant differences were found in complications, including nausea or vomiting (odds ratio [OR] 1.23, 95% CI 0.57-2.65, P = 0.59), fever (OR 1.55, 95% CI 0.96-2.51, P = 0.07), pulmonary complications (OR 1.41, 95% CI 0.82-2.43, P = 0.22), anastomotic leakage (OR 1.15, 95% CI 0.55-2.40, P = 0.70), paralytic ileus or small bowel obstruction (OR 1.80, 95% CI 0.57-5.70, P = 0.32), intra-abdominal abscess (OR 1.08, 95% CI 0.50-2.34, P = 0.84), wound infection (OR 1.29, 95% CI 0.56-2.96, P = 0.55), or wound dehiscence (OR 1.47, 95% CI 0.43-4.95, P = 0.54) between the two groups. A sensitivity analysis of the pooled data from high-quality studies and studies with >20 cases per group showed that the length of hospital stay was prolonged significantly in the decompression group compared with the nondecompression group.

CONCLUSIONS: Routine gastrointestinal decompression after gastrectomy does not promote the recovery of gastrointestinal function or reduce the incidence of postoperative complications. In our series, decompression was correlated with a prolonged interval to oral intake, a longer duration of hospitalization, and increased patient discomfort.
