BACKGROUND: After liver resection, the in-hospital observation periods associated with minimal risks for complications and unplanned readmission remains unclear. This study aimed to assess changes in risks of complications over time.
METHODS: Surgical complexity of liver resection was stratified into grades I (low complexity), II (intermediate), and III (high). The cumulative incidence rate and risk factors for complication ≥ Clavien-Dindo grade II (defined as treatment-requiring complications) were assessed.
RESULTS: Of 581 patients, grade I, II, and III resections were performed in 81 (13.9%), 119 (20.5%), and 381 patients (65.6%). Complexity grades (I vs. III, hazard ratio [HR] 0.45, P = 0.007; II vs. III, HR 0.60, P = 0.011) and background liver status (HR 1.76, P = 0.004) were risk factors for treatment-requiring complications. The cumulative incidence rate of treatment-requiring complications was higher after grade III resection than grade I resection (38.1% vs. 16.1%, P < 0.001) or grade II resection (38.1% vs. 25.2%, P = 0.019). Without cirrhosis/chronic hepatitis, the cumulative incidence rate of treatment-requiring complications decreased to less than 10% on postoperative day (POD) 3 after grade I resection, POD 5 after grade II resection, and POD 10 after grade III resection.
CONCLUSION: Conditional complication risk analysis stratified by surgical complexity may be useful for optimizing in-hospital observation.
