Background/purpose: To investigate the safety of laparoscopic liver resections (LLRs) for high-risk patients (HRs) with preoperative comorbidities affecting the heart, lungs, kidneys, glucose tolerance, and central nervous system.
Methods: This retrospective study included 585 patients who had undergone total hepatectomies from 2006 to 2020. Among them, 239 patients underwent LLRs, and 349 underwent open liver resections (OLRs). The safety and validity of LLRs were analyzed by comparing outcomes and preoperative records between HRs and nonhigh-risk patients (nHRs). HRs were defined as patients with any type of chronic heart disease rated New York Heart Association II or higher, chronic obstructive pulmonary disease rated stage III or higher, chronic kidney disease rated stage III or higher, insulin-dependent diabetes mellitus, or cerebrovascular disease with neurological sequelae.
Results: A total of 117 LLRs (49.0%) were performed in HRs, and there were more patients with ASA class III or higher than nHRs. Complications of Clavien-Dindo classification grade 3b or higher were not observed in HRs and in only one nHR. Furthermore, no postoperative exacerbations of the five HRs factors were observed in either group.
Conclusions: Rigorous assessment of surgical indications and perioperative management can promote safe LLRs, even in HRs with comorbidities.
