Impact of Intraoperative Gravity-Dependent Atelectasis Following Laparo scopic Liver Resection Performed in the Lateral Position

Laparoscopic liver resection (LLR) is currently an acceptable approach to surgery in select patients. The correlation between the intraoperative position and presence of gravity-dependent atelectasis (GDA) has been well discussed. However, LLR performed left half lateral position, relationship this GDA remains unclear. We evaluated extent which affects GDA. Furthermore, univariate multivariate analyses were identify potential risk factors for postoperative complications after with a special emphasis on by comparing various patient-, liver- surgeryrelated retrospective cohort. retrospectively 129 patients who underwent at Saitama Cancer Center Saitama, Japan, March 2011 July 2020. frequency duration investigated. divided cohort into groups without based cutoff value (≥ 5 days, n = 61 < 68, respectively). Using analysis, several independently assessed. Postoperative was observed (47%) lasted 1 8 days these mean 4.3 days. Multivariate logistic regression analysis revealed that or more (odds ratio [OR], 2.03; p 0.001) operating time > 388 minutes (OR, 5.31; independent LLR. incidence are considered useful predictors complications, should be assessed improve short-term outcomes undergoing
