Laparoscopic cholecystectomy using ultrasonically activated coagulating shears

Area of Science:

• Surgical Technology
• Minimally Invasive Surgery
• Gastrointestinal Surgery

Background:

• Ultrasonic energy is increasingly utilized for surgical cutting and coagulation.
• Laparoscopic cholecystectomy is a common procedure with various energy device options.
• Comparing new energy devices to established ones is crucial for optimizing surgical outcomes.

Purpose of the Study:

• To compare the effectiveness of ultrasonic energy versus monopolar electrosurgery in human laparoscopic cholecystectomy.
• To evaluate operative time, complications, and patient recovery between the two energy modalities.
• To determine if ultrasonically activated shears offer advantages over monopolar electrocautery.

Main Methods:

• A prospective randomized study involving 200 patients undergoing laparoscopic cholecystectomy.
• Patients were divided into two groups: Group A (monopolar electrocautery) and Group B (ultrasonically activated shears).
• Data collected included operating time, blood loss, bile leakage, drainage, fluid collections, and hospital stay.

Main Results:

• Ultrasonic shears group (Group B) had a shorter median operating time (37 min vs. 45 min) and significantly less blood loss (2 ml vs. 14 ml).
• Fewer patients in Group B required subhepatic drainage (26 vs. 37) and experienced bile leakage (0 vs. 3).
• Group B also showed fewer postoperative subhepatic fluid collections (1 vs. 5) and a shorter hospital stay (1.4 days vs. 1.9 days).

Conclusions:

• Ultrasonically activated coagulating shears are safer, easier, faster, and lead to less intraoperative and postoperative morbidity than monopolar electrocautery.
• This technology presents a superior option for laparoscopic cholecystectomy, enhancing patient safety and procedural efficiency.
• The study supports the adoption of ultrasonic shears for improved outcomes in gallbladder surgery.
