Abstract:
BACKGROUND Postoperative pulmonary complications (PPCs) after orthotopic liver transplantation (OLT) are associated with poor postoperative survival. However, there are no standard criteria for diagnosis of PPCs. This retrospective study aimed to explore the reliability of the Melbourne Group Scale version 2 (MGS-2) for determining PPCs after OLT. MATERIAL AND METHODS A total of 121 patients were divided into 3 groups. In the PPC and non-PPC groups, PPCs were determined to be present or absent in accordance with both the MGS-2 and the conventional broad criteria for diagnosis of PPCs; in the potential-PPC group, PPCs were determined to be present only in accordance with the conventional broad criteria. The perioperative risk factors for PPCs and prognosis of patients in potential-PPC group were all compared with non-PPC groups and PPC groups. RESULTS The preoperative characteristics of patients in the potential-PPC group were similar to those in non-PPC group. The length of intensive care unit stay (2.26±0.22 vs. 4.75±0.47 days; P=0.017), duration of hospitalization (33.33±1.70 vs. 48.78±2.53 days; P<0.001), and treatment cost (28.01±1.78 vs. 38.35±1.85×10 000 yuan; P=0.018) were significantly less in the potential-PPC group than in the PPC group. Furthermore, in accordance with the MGS-2 criteria for diagnosis of PPCs, patients with PPCs showed poorer overall survival rates than those without (P=0.038). CONCLUSIONS The MGS-2 appears to be a more suitable and reliable tool for diagnosis of PPCs and to identify the post-OLT patients with poorer perioperative characteristics and prognosis.
Insights
The Melbourne Group Scale version 2 (MGS-2) reliably identifies postoperative pulmonary complications (PPCs) after liver transplants. This scale helps predict poorer patient outcomes and guides clinical decisions for better care.
Area of Science:
- Transplantation Surgery
- Pulmonary Medicine
- Critical Care Medicine
Background:
- Postoperative pulmonary complications (PPCs) significantly impact survival after orthotopic liver transplantation (OLT).
- Current diagnostic criteria for PPCs lack standardization, creating a need for reliable assessment tools.
- The Melbourne Group Scale version 2 (MGS-2) was developed to standardize PPC diagnosis.
Purpose of the Study:
- To evaluate the reliability of the Melbourne Group Scale version 2 (MGS-2) for diagnosing PPCs following OLT.
- To compare the MGS-2 diagnostic criteria with conventional broad criteria for PPCs.
- To assess the prognostic value of MGS-2 identified PPCs on patient outcomes.
Main Methods:
- A retrospective study involving 121 patients undergoing OLT.
- Patients were categorized into PPC, non-PPC, and potential-PPC groups based on MGS-2 and conventional criteria.
- Perioperative risk factors and prognosis were compared across groups.
Main Results:
- Patients identified with PPCs using MGS-2 exhibited significantly longer intensive care unit stays, hospitalizations, and higher treatment costs compared to those without PPCs.
- The MGS-2 criteria correlated with poorer overall survival rates in patients with PPCs.
- Preoperative characteristics of the potential-PPC group were similar to the non-PPC group, suggesting MGS-2's distinct diagnostic capability.
Conclusions:
- The MGS-2 is a suitable and reliable tool for diagnosing PPCs after OLT.
- MGS-2 aids in identifying post-OLT patients with adverse perioperative characteristics and prognosis.
- Standardized diagnosis of PPCs using MGS-2 can improve patient management and outcomes.
