Laparoscopic common bile duct exploration versus open surgery: comparative prospective randomized trial.

Area of Science:

• Gastroenterology and Hepatobiliary Surgery
• Minimally Invasive Surgical Techniques
• Patient Safety and Outcomes

Background:

• Choledocholithiasis, or common bile duct stones, is a common condition requiring intervention.
• Traditional open common bile duct exploration carries risks and potential for complications.
• Advancements in laparoscopic surgery offer potential for improved patient outcomes.

Purpose of the Study:

• To compare the safety and efficacy of laparoscopic common bile duct (CBD) exploration versus open CBD exploration.
• To evaluate postoperative morbidity, mortality, and length of hospital stay between the two surgical approaches.

Main Methods:

• A prospective randomized trial involving 256 patients with CBD stones operated between 2005 and 2009.
• Patients were divided into two groups: laparoscopic CBD exploration (138 patients) and open CBD exploration (118 patients).
• Comorbidity assessed using the American Society of Anesthesiologists (ASA) score; preoperative imaging included ultrasound, ERCP, and MRCP.

Main Results:

• No statistically significant difference in patient comorbidity between groups.
• Mean operative time was 82 minutes for laparoscopic vs. 90 minutes for open procedures.
• Mean blood loss was significantly lower in the laparoscopic group (20 ml vs. 285 ml; p < 0.01).
• Postoperative complications were lower in the laparoscopic group (6.5%) compared to the open group (12.7%; p < 0.01).
• No mortality occurred in either group.

Conclusions:

• Laparoscopic CBD exploration is a highly efficient procedure with minimal morbidity and mortality.
• Laparoscopic approaches offer advantages over open operations regarding postoperative complications and hospital stay duration.
• Laparoscopic CBD exploration is a safe and beneficial treatment option for patients with common bile duct stones.
