Background/Aim:
Although the frequency of small bowel obstructions after liver surgery is generally considered low, previous studies have followed-up patients for less than a year, thus the incidence of small bowel obstructions several years after surgery is unknown. Furthermore, the rise in laparoscopic surgeries and the use of adhesion prevention materials may influence the occurrence of small bowel obstructions. This study aimed to assess the incidence of small bowel obstructions within a five-year period following liver surgery and identify the associated risk factors.
Patients And Methods:
This case series analysis analyzed patients who underwent liver surgery between April 2012 and March 2014 from 32 participating hospitals. Multivariate analysis was conducted to examine risk factors for small bowel obstructions.
Results:
A total of 953 patients were included in the analysis, and the incidence of small bowel obstructions was 1.6%. The incidence was significantly higher at 3.4% for surgeries related to metastatic liver cancer compared to other types of surgeries. Laparoscopic surgery had no significant effect on the incidence of SBO (p=0.72). There was no significant difference in the incidence of small bowel obstructions between surgeries that employed adhesion prevention materials and those that did not. Multivariable analysis revealed that longer surgical time and re-operation were independent risk factors for small bowel obstructions.
Conclusion:
The incidence of small bowel obstructions following surgery for metastatic liver cancer is significantly higher compared to other liver surgeries. Neither laparoscopic surgery nor adhesion prevention materials reduce its occurrence. Longer surgical time and re-operation are independent risk factors for small bowel obstructions.

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...
