Beyond Immunosuppression: Defining Perioperative Risk in Transplant Patients Undergoing Colorectal and Small Bowel...

Area of Science:

• Gastrointestinal surgery
• Transplantation medicine
• Immunosuppression management

Background:

• Transplant recipients present unique perioperative challenges for colorectal and small bowel surgery due to immunosuppression and comorbidities.
• Risks associated with these procedures in transplant patients are not well-defined.

Purpose of the Study:

• To analyze the perioperative risks and outcomes of colorectal and small bowel surgery in transplant recipients.
• To identify independent risk factors for adverse outcomes in this patient population.

Main Methods:

• Retrospective analysis of 237 transplant recipients undergoing colorectal or small bowel surgery.
• Evaluation of patient characteristics (transplant type, time since transplant, immunosuppression, comorbidity index) and surgical details.
• Analysis of postoperative outcomes including ICU stay, mortality, length of stay, and major morbidity (Dindo-Clavien ≥ 3).

Main Results:

• Adverse outcomes were significantly higher in emergency versus elective surgeries (e.g., mortality 25.6% vs. 6.2%).
• Independent risk factors included emergency surgery, colorectal surgery, and heart transplantation.
• Prednisolone use was associated with a reduced risk of adverse outcomes (OR 0.28).

Conclusions:

• Transplant recipients face considerable perioperative risks, especially with emergency gastrointestinal surgery and after heart transplantation.
• Primary anastomosis may be feasible in selected patients, suggesting tailored surgical strategies.
• Specialized, multidisciplinary care is essential for optimizing outcomes in this vulnerable population.
