Butterfly Traction: A New Standardized Approach for Gallbladder Bed Detachment in Laparoscopic Cholecystectomy

Area of Science:

• Minimally Invasive Surgery
• Surgical Techniques
• Gastrointestinal Surgery

Background:

• Gallbladder bed detachment (GBB-D) in laparoscopic cholecystectomy (LC) lacks a standardized technique.
• Butterfly traction (BT) was developed to optimize GBB-D.
• This study evaluates the effectiveness and standardization potential of BT.

Purpose of the Study:

• To evaluate the effectiveness of butterfly traction (BT) for gallbladder bed detachment (GBB-D) in laparoscopic cholecystectomy (LC).
• To assess the potential of BT as a standardized technique for GBB-D.
• To compare surgical outcomes between BT and non-standardized (NS) methods.

Main Methods:

• A retrospective comparison of 102 laparoscopic cholecystectomy (LC) cases (50 BT group, 52 NS group).
• Data collected included operative times, bile contamination, and blood loss.
• Analysis focused on outcomes, particularly in higher difficulty cases (Tokyo Guidelines Grade B/C).

Main Results:

• The BT group showed significantly lower rates of bile contamination (4% vs. 17%) and blood loss (0g vs. 1g) compared to the NS group.
• BT was particularly effective in higher difficulty cases, reducing operative time, blood loss, and perforations.
• The BT technique demonstrated benefits even when performed by surgeons with less experience (≤5 years).

Conclusions:

• Butterfly traction (BT) significantly improves surgical outcomes in laparoscopic cholecystectomy (LC), reducing bile contamination and blood loss.
• BT shows strong potential as a standardized technique for gallbladder bed detachment (GBB-D), enhancing safety and efficacy.
• The technique is beneficial across varying surgeon experience levels and case complexities.
