Aim:
Reconstruction with an ileosigmoidal anastomosis (ISA) or ileorectal anastomosis (IRA) is a surgical option after a subtotal colectomy. Anastomotic leakage (AL) is a problematic complication and high rates have been reported, but there is limited understanding of the risk factors involved. The aim of this study was to assess the established and potential predictors of AL following ISA and IRA.
Method:
This was a retrospective cohort study including all patients who had undergone ISA or IRA at three Swedish referral centres for colorectal surgery between January 2007 and March 2015. Data regarding clinical characteristics, treatment and outcome were collected from medical records. Univariate and multivariate logistic regression models were used to determine the association between patient and treatment related factors and the cumulative incidence of AL.
Results:
In total, 227 patients were included. Overall, AL was detected amongst 30 patients (13.2%). Amongst patients undergoing colectomy with synchronous ISA or IRA (one-stage procedure), AL occurred in 23 out of 120 (19.2%) compared with seven out of 107 (6.5%) after stoma reversal with ISA or IRA (two-stage procedure) (P = 0.004). In addition, the multivariate analyses revealed a statistically significantly lower odds ratio for AL following a two-stage procedure (OR 0.10, 95% CI 0.03-0.41, P = 0.001).
Conclusions:
This study confirms high rates of AL following ISA and IRA. In particular, a synchronous procedure with colectomy and ISA/IRA carries a high risk of AL.

01:30Inflammatory Bowel Disease II: Crohn's Disease
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.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
01:27Inflammatory Bowel Disease I: Ulcerative Colitis
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...
