Purpose:
This study was performed to clarify the clinical features of ischemic colitis (IC) after colorectal cancer surgery.
Methods:
This study retrospectively reviewed the medical records of 35 patients with IC. Patients were divided into two groups: those who had undergone colorectal cancer surgery (POIC group, n = 13) and those who had not undergone colorectal cancer surgery (NOIC group, n = 22). Gangrenous colitis was seen in one patient in the POIC group, and transient colitis was seen in the remaining 34 patients.
Results:
Among the patients with transient colitis, there were significantly more patients without underlying diseases or promoting factors in the POIC group than in the NOIC group (P = 0.01). Abdominal pain was more frequently reported in the NOIC group than in the POIC group as both the initial symptom (P = 0.02) and throughout the disease course (P = 0.02). Ischemic changes occupying more than half the circumference of the intestinal wall were more frequently found in the NOIC group than in the POIC group (P = 0.03).
Conclusions:
Although transient POIC may occur without any underlying disease, severe symptoms rarely occur. However, if POIC occurs in a patient with severe underlying disease, then the occurrence of severe colitis should be considered.

Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

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.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...
