Robotic extended cholecystectomy in gallbladder cancer

Area of Science:

• Surgical Oncology
• Minimally Invasive Surgery
• Robotic Surgery

Background:

• Minimally invasive surgery (MIS) for advanced gallbladder cancer (GBC) presents challenges in achieving complete oncologic resection.
• Robotic systems may overcome limitations of laparoscopic MIS in complex procedures like extended cholecystectomy.

Purpose of the Study:

• To evaluate the feasibility and benefits of using robotic systems for extended cholecystectomy in advanced GBC patients.

Main Methods:

• Retrospective analysis of 16 patients with suspected stage T2 or higher GBC undergoing robotic extended cholecystectomy (REC).
• Detailed description of surgical steps including trocar placement, lymph node dissection (stations 8, 9, 12, 13), and liver resection.

Main Results:

• Mean operation time was 198.3 minutes with median blood loss of 295 ml.
• All 16 patients achieved tumor-free resection margins; 11 had confirmed advanced GBC (stage T2+).
• Median hospital stay was 7 days with no perioperative mortality or 90-day recurrence.

Conclusions:

• Robotic systems are safe and effective for advanced GBC requiring extended cholecystectomy.
• REC facilitates oncologically sound lymph node dissection and contributes to faster patient recovery.
