Magnitude and predictors of unfavorable management outcome in surgically treated patients with intestinal obstruction in Ethiopia: a systematic review and meta-analysis

Abstract

BackgroundUnless an emergency surgical intervention is conducted, intestinal obstruction may result in high morbidity and mortality. In Ethiopia, the magnitude and predictors of unfavorable management outcomes in surgically treated patients with intestinal obstruction are highly variable and inconsistent. The aim of this study was; therefore, to estimate the overall prevalence of unfavorable management outcome and its predictors among surgically treated patients with intestinal obstruction in Ethiopia.MethodWe searched articles from databases from June 1, 2022, to August 30, 2022. Cochrane Q test statistics and I2 tests were applied. We used a random-effect meta-analysis model to overcome the impact of heterogeneity among the included studies. In addition, the association between risk factors and unfavorable management outcome in surgically treated patients with intestinal obstruction was investigated.ResultsThis study included a total of twelve articles. The pooled prevalence of unfavorable management outcome in surgically treated patients with intestinal obstruction was 20.22% (95% CI: 17.48–22.96). According to a sub-group analysis by region, Tigray region had the highest prevalence of poor management outcome, which was 25.78% (95% CI: 15.69–35.87). Surgical site infection was the most commonly reported symptom of poor management outcome (8.63%; 95% CI: 5.62, 11.64). The length of postoperative hospital stays (95% CI: 3.02, 29.08), duration of illness (95% CI: 2.44, 6.12), presence of comorbidity (95% CI: 2.38, 10.11), dehydration (95% CI: 2.07, 17.40), and type of intraoperative procedure (95% CI: 2.12, 6.97) were all significantly associated with unfavorable management outcome of intestinal obstruction among surgically treated patients in Ethiopia.ConclusionAccording to this study, the magnitude of unfavorable management outcome was high among surgically treated patients in Ethiopia. Unfavorable management outcome was significantly associated with the length of postoperative hospital stays, duration of illness, comorbidity, dehydration, and type of intraoperative procedure. Medical, surgical and public health measures are pivotal to reduce unfavorable management outcome in surgically treated intestinal obstruction patients in Ethiopia.
