Purpose: The purpose of the systematic review and meta-analysis is to analyze the application value of the stoma support rods in loop enterostomy.
Methods: The studies on the application of stoma rods in loop enterostomy published from January 2000 to January 2020 were searched in the databases of PubMed, Embase, Cochrane library, and Clinical trials. All randomized controlled trials (RCTs) and cohort studies that observed the value of stoma rods were included according to inclusion criteria. The RevMan5.3 software was used for statistical analysis.
Results: A total of 1131 patients with loop enterostomy in six studies were included in this study; there were 569 cases in the experimental group and 562 cases in the control group. All six studies analyzed the effect of support rods on the incidence of stoma retraction; the meta-analysis showed that in a total of 32 patients, stoma retraction occurred, with a total incidence of about 2.8% in 1131 patients. The incidence of stoma retraction in the rod group was not significantly lower than that in the non-rod group, and the difference was not statistically significant (OR = 0.65, 95% CI 0.32~1.32, I2 = 0%, P = 0.23), and the studies were homogeneous. The incidences of stoma necrosis (OR = 6.41, 95% CI 2.22~18.55, I2 = 0%, P = 0.0006), peristomal dermatitis (OR = 2.93, 95% CI 2.01~4.27, I2 = 0%, P < 0.00001), and mucocutaneous separation (OR = 2.14, 95% CI 1.03~4.47, I2 = 0%, P = 0.04) were significantly increased in the rod group.
Conclusions: It is not recommended to routinely use stoma support rods in the clinical practice.
