Application of the IDEAL framework in hepatopancreatobiliary surgery: a review of the literature

PURPOSE

To evaluate every stage of surgical innovation and generate high-quality research evidence, the IDEAL (Idea, Development, Exploration, Assessment, Long-term study) framework was developed. This study aimed to explore the application of the IDEAL framework in hepatopancreatobiliary surgery and identify factors limiting its dissemination.

METHODS

We conducted a citation search of 8 core IDEAL framework articles in PubMed, Embase, Web of Science, and Scopus databases from 2009 to 2022. Two independent reviewers screened and selected articles related to hepatopancreatobiliary surgery.

RESULTS

A total of 1621 articles were identified through citation search. Following screening, 132 articles were finally retained, including 75 original studies (57%) and 57 secondary studies (43%). Of the original studies, only 10 articles (13%) accurately applied the IDEAL framework in methodology, distributed as follows: 1 in pre-IDEAL stage (0), 2 in Idea stage (1), 7 in Development stage (2a), 1 in Exploration stage (2b), and no articles in Assessment and Long-term study stages (3, 4). In the secondary studies, 36 articles (63%) mentioned and discussed the IDEAL framework, and all supported its application.

CONCLUSIONS

The application of the IDEAL framework in hepatopancreatobiliary surgery is increasingly widespread, as evidenced by its substantial citation in numerous articles. However, the utilization of the IDEAL framework remains predominantly confined to the early stages of innovation in hepatopancreatobiliary surgery, coupled with instances of misapplication stemming from insufficient comprehension of the framework. Further efforts are necessary to extend the impact of the IDEAL framework and provide surgeons with comprehensive guidance for its judicious implementation.

The Future Liver Remnant : Definition, Evaluation, and Management

When considering patients for a major hepatectomy, one must carefully consider the volume of liver to be left behind and if additional procedures are necessary to augment its volume. This review considers the optimal volume of the future liver remnant (FLR) and analyzes the techniques of augmenting this volume, the various growth parameters to assess adequate growth of the FLR, as well as further management when there has been inadequate growth of the FLR.

ALPPS in right trisectionectomy: a safe procedure to avoid postoperative liver failure?

INTRODUCTION

To induce rapid hepatic hypertrophy and to reduce post-hepatectomy liver failure (PHLF), associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) has been recently developed for patients with a limited future liver remnant. The aim of this study was to further assess the perioperative risk of this procedure and its specific indications.

PATIENTS AND METHODS

The study was performed between November 2010 and April 2012 for patients undergoing right trisectionectomy by the ALPPS approach. Liver volume, intra- and postoperative complications, including PHLF, and residual tumour status were compared for patients with different diagnoses.

RESULTS

The interval between two operations in nine patients undergoing ALPPS was 13 days (median). Sufficient hepatic hypertrophy was achieved with a volume gain of 87.2 % (median). All patients underwent right trisectionectomy without residual tumours. In contrast to six patients with uneventful intra- and postoperative course, bile leak, vancomycin-resistant enterococcus infection, PHLF and sepsis developed in two of three patients with hilar cholangiocarcinoma as the preoperative diagnosis.

CONCLUSION

ALPPS leads to sufficient hepatic hypertrophy within 2 weeks, avoiding PHLF in most patients. In patients with hilar cholangiocarcinoma, ALPPS should be applied with extreme caution due to high morbidity and mortality.
