Objectives:
Colorectal perforation is associated with high morbidity and mortality rates after surgery. We investigated various clinical features of patients who underwent emergency surgery for colorectal perforation and explored the risk factors for postoperative complications and hospital mortality.
Methods:
Data from 147 patients who underwent surgery for colorectal perforation were retrospectively reviewed. We investigated various clinical and operative factors, including inflammation-based prognostic scores (IBPSs), and evaluated the risk factors for postoperative complications and hospital mortality due to colorectal perforation.
Results:
Among 147 patients, the most frequent postoperative complication was wound infection (32 cases, 21.8%), followed by intra-abdominal abscesses (27 cases, 18.4%) after surgery for colorectal perforation. Time from onset to surgery ≥ 2 days (Hazard ratio [HR] = 2.810, p = 0.0383) and prognostic nutritional index (PNI) < 30 (HR = 3.190, p = 0.0488) were identified as risk factors for intra-abdominal abscess, while neutrophil-lymphocyte ratio (NLR) < 6.15 (HR = 5.020, p = 0.0009) was identified as a risk factor for wound infection. Time from onset to surgery ≥ 2 days (HR = 7.713, p = 0.0492), severe postoperative complications (Clavien-Dindo grade ≥ IIIa) (HR = 10.98, p = 0.0281), and platelet-lymphocyte ratio (PLR) < 144 (HR = 18.84, p = 0.0190) were independent predictive factors for hospital mortality.
Conclusions:
Time from onset to surgery and IBPSs such as PNI, NLR, and PLR, may be associated with postoperative complications and hospital mortality due to colorectal perforation.

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...
