Abstract

Background

Posthepatectomy liver failure (PHLF), the most serious complication after hepatectomy, may evoke multisystemic complications and even mortality. Despite numerous studies demonstrated the safety and efficacy of controlled low central venous pressure (CLCVP), the optimal central venous pressure (CVP) maintenance level during CLCVP and its relationship with PHLF remain controversial. Therefore, the present study aimed to evaluate the association between the lowest CVP maintenance level during CLCVP and PHLF.

Methods

755 patients who underwent laparoscopic hepatectomy at Sun Yat-Sen Memorial Hospital between January 2017 and March 2021 were recruited. Univariate and multivariate analyses were performed to determine the effect of the lowest CVP maintenance level on PHLF. After implementing propensity score matching (PSM) to equalize demographic confounders, univariate comparisons and subgroup analyses were conducted to investigate the impact of the lowest CVP maintenance level on PHLF in patients who underwent CLCVP.

Results

Univariate and multivariate analyses identified intraoperative lowest CVP maintenance level < 2 mmHg as an independent risk factor for PHLF (P = 0.041; OR, 0.520; 95% CI 0.277 to 0.974). Following 1:1 PSM in individuals who received CLCVP, the lowest CVP maintenance level < 2 mmHg was associated with heightened PHLF incidence (P = 0.048) and elevated intraoperative lactate level (P = 0.011). Subgroup analyses revealed that the above effect of the lowest CVP maintenance level occurred mainly in elderly individuals or those with prolonged portal blockade.

Conclusion

During laparoscopic hepatectomy, excessively low CVP maintenance level should be avoided to decrease the risk of tissue malperfusion and PHLF, especially in elderly or prolonged portal blockade patients.
