Summary
Single-incision laparoscopic cholecystectomy (SILC) using a modified dome-down approach is feasible and safe. This technique improves visualization, potentially reducing bile duct injury risk during gallbladder removal.
Area of Science:
- Minimally Invasive Surgery
- Gastrointestinal Surgery
- Surgical Safety
Background:
- Single-incision laparoscopic cholecystectomy (SILC) may elevate bile duct injury risk due to limited operative exposure.
- The dome-down approach allows circumferential evaluation of the cystic duct before division, mitigating injury risks.
Purpose of the Study:
- To assess the feasibility and safety of SILC employing a modified dome-down technique.
- To evaluate the use of conventional laparoscopic instruments in this approach.
Main Methods:
- A single transumbilical incision with three 5-mm trocars was utilized.
- An extralong 30º laparoscope and transabdominal gallbladder fundus retraction were employed.
- Dissection proceeded retrograde from the gallbladder body to the porta hepatis, ensuring 360º visualization of the cystic duct junction.
Main Results:
- Sixteen patients (mean age 31) underwent the procedure for cholelithiasis or acute cholecystitis.
- Mean operative time was 80.3 minutes with minimal blood loss.
- All patients were discharged within 24 hours, with no complications and a nearly invisible umbilical scar at 1-month follow-up.
Conclusions:
- SILC with the modified dome-down approach is technically feasible using standard instruments.
- The technique offers excellent delineation of ductal anatomy, enhancing safety.
- This approach may reduce bile duct injury risk, particularly for surgeons new to SILC.
