Correlation between anthropometric data and preparatory maneuvers difficulties during laparoscopic right liver...

Area of Science:

• Minimally Invasive Surgery
• Hepatobiliary Surgery
• Surgical Oncology

Background:

• Laparoscopic right liver resections (LRLR) present unique accessibility challenges.
• Previous studies suggest anthropometric data, beyond Body Mass Index (BMI), may predict surgical outcomes.
• Understanding factors influencing LRLR difficulty is crucial for surgical planning and patient safety.

Purpose of the Study:

• To investigate the correlation between specific anthropometric measurements and the difficulty encountered during preparatory maneuvers in LRLR.
• To determine if anthropometric data can predict challenges in liver mobilization and vessel isolation during LRLR.

Main Methods:

• Prospective study of 65 patients undergoing LRLR requiring full liver mobilization.
• Surgeons rated difficulty of liver mobilization (LM) and right hepatic vein isolation (RHVI) on a 5-point scale.
• Collected data included cranio-caudal liver diameter (CCliv), CHALLENGE Index (CCliv/abdomen diameter), and procedure times.

Main Results:

• Larger CCliv correlated with longer times for RHVI and LM.
• Higher CHALLENGE Index correlated with longer RHVI times and increased difficulty in RHV isolation.
• Liver manipulation difficulty increased with latero-lateral liver diameter; BMI showed no correlation with difficulty or maneuver times.

Conclusions:

• Anthropometric data, specifically liver and abdominal dimensions, are valuable predictors of preparatory maneuver difficulty in LRLR.
• These measurements can aid in anticipating surgical challenges, optimizing planning for LRLR.
• BMI is not a reliable predictor of difficulty in LRLR preparatory stages.
