Laparoscopic sleeve gastrectomy using the LiVac liver retractor system: technical report

Area of Science:

• Bariatric Surgery
• Surgical Technology
• Gastrointestinal Surgery

Background:

• Laparoscopic sleeve gastrectomy (LSG) requires clear exposure of the angle of His (AOH) for safe execution.
• Liver retraction is a critical step in achieving adequate AOH visualization during LSG.

Observation:

• A novel internal liver retractor, the LiVac, was evaluated for its utility in LSG procedures.
• The study involved the application of the LiVac in 20 patients undergoing LSG.

Findings:

• The LiVac device facilitated successful exposure of the AOH in all 20 patients.
• The mean operative time was 88 minutes, with no procedure-related complications or morbidities observed.
• Postoperative liver enzyme levels (AST and ALT) showed minimal changes, indicating no significant hepatic injury.

Implications:

• The LiVac represents a technically feasible and safe option for liver retraction in LSG.
• This device may enhance surgical efficiency and patient safety in laparoscopic bariatric procedures.
• Further studies can explore the long-term benefits and broader application of the LiVac in various laparoscopic surgeries.
