Early severe digestive complications after lung transplantation

Area of Science:

• Gastroenterology
• Thoracic Surgery
• Transplantation Medicine

Background:

• Lung transplantation (LT) is a life-saving procedure for end-stage lung disease.
• Early severe digestive complications (ESDC) can significantly impact post-transplant outcomes.
• Understanding the incidence and risk factors of ESDC is crucial for improving patient care.

Purpose of the Study:

• To describe and analyze the incidence of early severe digestive complications (ESDC) following lung transplantation (LT).
• To identify associated risk factors for ESDC after LT.
• To evaluate the impact of ESDC on early patient outcomes.

Main Methods:

• Retrospective study of 351 patients undergoing LT without cardiopulmonary bypass (CPB) from March 1988 to December 2009.
• ESDCs defined as gastrointestinal complications within 30 days post-LT or during initial hospitalization, jeopardizing survival or requiring invasive therapy.
• Analysis of patient characteristics, risk factors, and outcomes related to ESDC.

Main Results:

• ESDC occurred in 7.4% of patients, with acute cholecystitis being the most common type (38%).
• ESDC significantly prolonged hospitalization (96 days vs. 55 days, p < 0.0001) and led to death in 19% of affected patients.
• Older age and bilateral LT were identified as significant risk factors for ESDC.

Conclusions:

• ESDC represent a significant complication after LT without CPB, affecting 7.4% of patients.
• These complications are associated with prolonged hospital stays and increased mortality.
• Older recipient age and bilateral LT are key risk factors, informing recipient selection and procedural choices.
