Abstract

Background: Following the publication of reports from landmark international consensuses (Louisville 2008 and Morioka 2014), minimally invasive hepatectomy became widely accepted as a legitimate alternative to open surgery. We aimed to compare the operative, hospitalization, and total economic costs of open (OLR) vs. laparoscopic (LLR) vs. robotic liver resection (RLR). Methods: We performed a systematic literature review (end-of-search date: July 3, 2020) according to the PRISMA statement. Random-effects meta-analyses were conducted. Quality assessment was performed with the Cochrane Risk of Bias tool for randomized controlled trials, and the Newcastle–Ottawa Scale for non-randomized studies. Results: Thirty-eight studies reporting on 3847 patients (1783 OLR; 1674 LLR; 390 RLR) were included. The operative costs of LLR were significantly higher than those of OLR, while subgroup analysis also showed higher operative costs in the LLR group for major hepatectomy, but no statistically significant difference for minor hepatectomy. Hospitalization costs were significantly lower in the LLR group, with subgroup analyses indicating lower costs for LLR in both major and minor hepatectomy series. No statistically significant difference was observed regarding total costs between LLR and OLR both overall and on subgroup analyses in either major or minor hepatectomy series. Meta-analyses showed higher operative, hospitalization, and total costs for RLR vs. LLR, but no statistically significant difference regarding total costs for RLR vs. OLR. Conclusion: LLR’s higher operative costs are offset by lower hospitalization costs compared to OLR leading to no statistically significant difference in total costs, while RLR appears to be a more expensive alternative approach. © 2021, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.

Abstract

Background: Biomarkers for the diagnostic classification of pancreatic cysts are urgently needed. Deregulated microRNA (miRNAs) expression is widespread in pancreatic cancer. We assessed whether aberrant miRNAs in pancreatic cyst fluid could be used as potential biomarkers for cystic precursor lesions of pancreatic cancer. Methods: Cyst fluid specimens were prospectively collected from 40 surgically resected pancreatic cysts, and small RNAs were extracted. The ‘mucinous’ cohort included 14 intraductal papillary mucinous neoplasms (including 3 with an associated adenocarcinoma) and 10 mucinous cystic neoplasms; the ‘nonmucinous’ cohort included 11 serous cystadenomas and 5 other benign cysts. Quantitative reverse transcription PCR was performed for five miRNAs (miR-21, miR-155, miR-221, miR-17-3p, miR-191), which were previously reported as overexpressed in pancreatic adenocarcinomas. Results: Significantly higher expression of miR-21, miR-221, and miR-17-3p was observed in the mucinous versus nonmucinous cysts (p < 0.01), with the mean relative fold differences being 7.0-, 7.9-, and 5.4-fold, respectively. Receiver operating characteristic curves demonstrated the highest median area under the curve for miR-21, with a median specificity of 76%, at a sensitivity of 80%. Conclusion: This pilot study demonstrates that profiling miRNAs in pancreatic cyst fluid samples is feasible and can yield potential biomarkers for the classification of cystic lesions of the pancreas.
