摘要

Background

Neutropenic enterocolitis is a serious gastrointestinal complication that can develop in patients undergoing chemotherapy or other immunosuppressive treatments. It is characterized by inflammation and necrosis of the bowel, and most commonly affects the cecum and ascending colon. Although individual case reports have described the features of NE, a comprehensive synthesis of all the published cases is required.

Methods

A systematic search of the literature databases was conducted to identify all NE case reports. Data on patient demographics, clinical presentation, diagnostic findings, treatment approaches, and outcomes were independently extracted by the five reviewers. Generalized estimating equations were used to examine the associations between variables.

Results

In total, 227 cases from 159 publications met the inclusion criteria. Most cases occur in patients with hematological cancers undergoing chemotherapy. Common presentations include abdominal pain, fever, and diarrhea. Imaging typically shows a thickening of the bowel wall. Broad-spectrum antibiotics and bowel rest were the primary initial treatment. The overall mortality rate was 33.5%. While statistical analyses did not find significant associations, factors showing clinically significant increased odds for mortality included sepsis, multiorgan failure, and isolated ileocecal valve involvement, potentially representing important prognostic indicators.

Conclusion

This systematic review and meta-analysis provides the largest consolidated analysis of NE cases. It identifies typical clinical features and helps characterize risk factors and prognostic indicators to aid in the early diagnosis and management of this potentially lethal complication.
