A Systematic Review of Early versus Late Closure of Loop Ileostomy

INTRODUCTION: A Loop ileostomy is one of the most common techniques used in colorectal surgery to establish a reversible faecal diversion and bypass the large bowels, in order to protect either a downstream colorectal anastomosis or a coloanal anastomosis. However, it is a procedure that can cause a plethora of complications including long term ones such as the psychological effects. Currently, there is no consensus regarding the optimal time to perform closure of a loop ileostomy. Some studies suggested the early reversal of ileostomy procedure as a solution to reduce these complications. This study aims to review the available literature in order to ascertain the benefits behind early closure of loop ileostomy. METHODS: The literature was searched for all studies that included a comparison between the outcomes of early and late closure of loop ileostomy in terms of morbidity, mortality, or quality of life, where available. Early closure of loop ileostomy is defined as closure less than three months and late as more than three months, in accordance with conventional literature. The resultant articles were filtered using our inclusion and exclusion criteria. Finally, the remaining articles were assessed for quality and their results were compared to one another in order to draw our conclusions. Results and Discussion. The results were slightly inclined toward early closure of loop ileostomy. However, there were limitations of the studies reviewed, including the heterogenicity of studies, selection bias, lack of clear definition of measured outcomes, and small sample size. Taking that into consideration, the results of early closure of loop ileostomies in the selected patients were promising and require further investigation.
