Purpose:
Postoperative management for colonic perforation is an important prognostic factor, but whether intensivists perform postoperative management varies between institutions.
Methods:
We investigated 291 patients with colonic perforation between 2018 and 2022. Patients were divided into those managed by an intensivists (ICU group; n = 40) and those not managed by an intensivists (non-ICU group; n = 251). We examined how management by intensivists affected prognosis using inverse probability weighting, and clarified which patients should consult an intensivists.
Results:
The ICU group showed a significantly higher shock index (1.15 vs. 0.75, p < 0.01), higher APACHE II score (16.0 vs. 10.0, p < 0.001), and more severe comorbidities (Charlson Comorbidity Index 5.0 vs. 1.0, p < 0.001) and general peritonitis (85% vs. 38%, p < 0.001). Adjusted risk differences were - 24% (-34% to -13%) for 6-month mortality rate. Six-month mortality was improved by ICU intensivist management in patients with general peritonitis (risk difference - 22.8; 95% confidence interval - 34 to -11); APACHE II score ≥20 (-0.79; -1.06 to -0.52); lactate ≥1.6 (-0.38; -0.57 to -0.29); shock index ≥1.0 (-40.01; -54.87 to -25.16); and catecholamine index ≥10 (-41.16; -58.13 to -24.19).
Conclusions:
Intensivists were involved in treating patients in poor general condition, but prognosis was extremely good. Appropriate case consultation with intensivists is important.

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...
