Clinical Scorecard: Evaluating the Effects of Minimally Invasive Right Hepatectomy in Living Liver Donation: A Meta-Analysis

At a Glance

Key Highlights

• A2ALDLT with right lobe donation is considered high risk, especially in Western countries.
• MILR has been proposed to reduce donor postoperative complications compared to OLR.
• This meta-analysis included 15 retrospective studies with 2094 donors (553 MILR, 1541 OLR).

Guideline-Based Recommendations

Diagnosis

• Careful donor selection and evaluation prior to right hepatectomy for A2ALDLT.

Management

• Consider MILR approach to potentially reduce operative risks and postoperative complications in right hepatectomy donors.
• Perform surgery in experienced centers with expertise in minimally invasive liver surgery.

Monitoring & Follow-up

• Monitor intraoperative parameters such as duration of surgery and blood loss.
• Postoperative monitoring of liver enzymes (AST, ALT) and complications using Dindo-Clavien classification.

Risks

• Right lobe donation carries significant donor risk; MILR aims to minimize these risks but requires further validation.
• Potential for conversion from MILR to open surgery should be anticipated.

Patient & Prescribing Data

Adults undergoing right hepatectomy for living liver donation in A2ALDLT.

MILR may decrease postoperative adverse events and hospitalization duration compared to OLR, but evidence is based on retrospective studies.

Clinical Best Practices

• Follow PRISMA guidelines for systematic review and meta-analysis when evaluating surgical approaches.
• Use standardized complication grading systems (e.g., Dindo-Clavien) for consistent outcome reporting.
• Perform data extraction and study selection with independent reviewers to minimize bias.
• Assess study quality using tools like Robins-I for non-randomized intervention studies.
• Apply appropriate statistical models based on heterogeneity (fixed or random effects).
