Aim:
Prolonged postoperative ileus (PPOI) after colorectal surgery remains a leading cause of delayed postoperative recovery and prolonged hospital stay. Its exact incidence is unknown. The aim of this systematic review is to investigate the definitions and incidence of PPOI previously described.
Method:
MEDLINE, Embase and the Cochrane Database of Systematic Reviews (up to July 2014) were searched. Two authors independently reviewed citations using predefined inclusion and exclusion criteria.
Results:
The search strategy yielded 3233 citations; 54 were eligible, comprising 18 983 patients. Twenty-six studies were prospective [17 of these being randomized controlled trials (RCTs)] and 28 were retrospective. Meta-analysis revealed an incidence of PPOI of 10.3% (95% CI 8.4-12.5) and 10.2% (95% CI 5.6-17.8) for non-RCTs and RCTs, respectively. Significant heterogeneity was observed for both non-RCTs and for RCTs. The used definition of PPOI, the type of surgery and access (laparoscopic, open) and the duration of surgery lead to significant variability of reported PPOI incidence between studies. The incidence of PPOI is lower after laparoscopic colonic resection.
Conclusion:
There is a large variation in the reported incidence of PPOI. A uniform definition of PPOI is needed to allow meaningful inter-study comparisons and to evaluate strategies to prevent PPOI.

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
