A temporary loop ileostomy affects renal function

Area of Science:

• Nephrology
• Gastroenterology
• Surgical Oncology

Background:

• Temporary loop ileostomies are common surgical procedures.
• Renal morbidity following ileostomy closure is not well-established.
• Identifying preoperative risk factors for renal impairment is crucial.

Purpose of the Study:

• To evaluate renal morbidity after temporary loop ileostomy.
• To identify preoperative risk factors associated with renal impairment post-ileostomy.

Main Methods:

• Retrospective study of 308 patients undergoing temporary loop ileostomy and closure.
• Serum creatinine and estimated glomerular filtration rate (eGFR) were measured before surgery and before closure.
• CKD-EPI formula was used to calculate eGFR.

Main Results:

• A significant decrease in eGFR was observed at ileostomy closure (89 to 83, p < 0.0001).
• The prevalence of renal impairment (eGFR <60) increased from 7.5% to 21% (p < 0.0001).
• Advanced age and hypertension were identified as preoperative risk factors for reduced eGFR.

Conclusions:

• Temporary loop ileostomy is associated with reduced renal function in most patients.
• Older and hypertensive patients are at higher risk for renal impairment.
• Consideration of alternative stoma types and careful patient selection are recommended for at-risk individuals.
