Background: Post-hepatectomy liver failure (PHLF) is considered a main reason for death after major hepatectomy. The reported PHLF-related mortality differs largely and the data mainly originate from single centers. Aim: A retrospective, population-based register study was designed to evaluate the impact of PHLF on 90-day mortality after hepatectomy. Method: All patients who underwent liver resection in Sweden between 2005 and 2009 were retrospectively identified using the Swedish Hospital Discharge Registry. 30-and 90-day mortality were identified by linkage to the Registry of Causes of Death. Additional clinical data were obtained from the medical charts in all seven university hospitals in Sweden. PHLF was defined according to Balzan criteria (Bilirubin >50 mg/L and international normalized ratio >1.5) on postoperative day 5. Results: A total of 2461 liver resections were performed (2194 in university hospitals). 30-and 90-day mortality were 1.3% and 2.5%, respectively. 90-day mortality at university hospitals was 2.1% (n ¼ 46). In 41% (n ¼ 19) of these patients, PHLF alone or in combination with multi-organ failure was identified as cause of death. Between the PHLF and non-PHLF group, there was no significant difference regarding age, sex, American Society of Anesthesiologists-classification, or preoperative chemotherapy. Cholangiocarcinoma as indication for surgery, need for vascular reconstruction and an extended resection were significantly overrepresented in the PHLF-group. Between groups, the incidence of 50:50 criteria differed significantly already on postoperative day 3.
Conclusion:Overall mortality is very low after hepatectomy in Sweden. PHLF represents the single most important cause of death even in a population-based setting.
PurposeThe aim of this study was to investigate whether associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) can be used as an effective and safe rescue procedure in patients with colorectal liver metastases (CRLM) and insufficient effect on the future liver remnant (FLR) after previous portal vein occlusion (PVO).MethodsEleven patients with bilobar CRLM treated with neoadjuvant chemotherapy and previous PVO with insufficient effect on the FLR were analyzed retrospectively from a prospective database. FLR was evaluated with computed tomography volumetry 6 days after stage 1, and stage 2 was performed on day seven.ResultsSix days after stage 1, the median increase of the FLR was 209 ml (range 87–314, P < 0.001). This corresponded to a median FLR growth of 61.8 % (range 19.3–120) resulting in an FLR/BW ratio >0.5 % in all patients and successful subsequent removal of the tumor bearing liver (segments IV–VIII) in all patients with no 90-day mortality. No patient had a 3b-complication or more according to Clavien-Dindo. No patient developed severe posthepatectomy liver failure.ConclusionsThe powerful hypertrophy of the FLR associated with ALPPS seems to be maintained in patients with CRLM and previous failed PVO.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
