Preoperative Risk Factors for 30-Day Reoperation in Patients Undergoing Hepatic Resections for Malignancy

Area of Science:

• Hepatobiliary Surgery
• Surgical Oncology
• Patient Safety

Background:

• Hepatic resections are generally safe procedures.
• Reoperation within 30 days of liver resection is a significant adverse event.
• Identifying predictive factors for reoperation is crucial for patient management.

Purpose of the Study:

• To identify preoperative risk factors associated with 30-day reoperation after hepatic resection for malignancy.
• To improve patient selection and expectation setting for liver resection surgery.

Main Methods:

• Retrospective analysis of 4812 patients undergoing liver resection for malignancy from 2005-2010 using the American College of Surgeons-National Surgical Quality Improvement Program (NSQIP) database.
• Identification of patients using CPT and ICD-9 codes.
• Univariate and multivariate logistic regression analysis to determine associations between preoperative characteristics and 30-day reoperation.

Main Results:

• Male gender, dependent functional status, intrahepatic primary biliary cancer, history of angina, and preoperative wound infection were significantly associated with increased risk of 30-day reoperation.
• Overall mortality was 2.7% and morbidity was 28.2% in the study cohort.

Conclusions:

• Preoperative risk factors significantly influence the likelihood of reoperation within 30 days following liver resection for cancer.
• Identifying these risk factors allows for better patient optimization and informed consent regarding potential complications.
