Background:
The aims of this study were to analyze the relationship between the different causes of immunosuppression (IMS) and diverticulitis.
Methods:
IMS patients admitted for colonic diverticulitis were included in the study. Patients were divided in 5 groups according to the reasons of IMS: group I, chronic corticosteroid therapy; group II, transplant patients; group III, malignant neoplasm disease; group IV, chronic renal failure; group V, others immunosuppressant treatment. Rate of emergency surgery, outcomes in terms of postoperative mortality, and recurrence rate after nonoperative management were analyzed according to the reason of IMS.
Results:
Emergency surgery was performed in 76 patients (39.3%). It was needed more frequently in group I. Overall, postoperative mortality was of 31.6% and recurrence rate after successful nonoperative management occurred in 30 patients (27.8%). No differences were observed among the groups.
Conclusions:
The rate of emergency surgery in IMS patients at the first episode of acute colonic diverticulitis is high. Elective surgery in IMS patients should be individually indicated according to persistence of symptoms or early recurrences.

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...

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...
