Robotic Hepatic Bisegmentectomy (s4b+s5) and Hilar Lymphadenectomy for Incidental Gallbladder Cancer Using Glissonian Approach

BackgroundGallbladder carcinoma is a rare cancer with a poor prognosis and the most common biliary tract malignancy. This video shows robotic treatment of a patient with incidental gallbladder cancer diagnosed after laparoscopic cholecystectomy. The operation consisted of a robotic bisegmentectomy (liver segments 4b and 5) using a Glissonian approach and a hilar lymphadenectomy.MethodsA 73-year-old woman with no relevant history underwent a laparoscopic cholecystectomy at another hospital facility. The pathology revealed a gallbladder carcinoma. The patient was then referred for further treatment. Pathologic revision confirmed T2a carcinoma and staging was negative for distant metastases. The multidisciplinary team decided on a radical resection that will consist of a hilar lymphadenectomy and a frozen section of the cystic stump along the resection of segments 4b and 5. A robotic approach was proposed, and consent was obtained.ResultsThe operation time was 300 min and was performed 21 days after the cholecystectomy. Estimated blood loss was 120 mL with no transfusions required during or after the procedure. The postoperative recovery was uneventful, and the patient was discharged on the fourth postoperative day. The final pathology showed no residual disease in the liver specimen and no metastases among 16 removed lymph nodes.ConclusionsThe robotic approach is safe and feasible for radical treatment after incidentally discovered gallbladder cancer. The Glissonian approach is useful for anatomic resection of liver segments 4b and 5. This video can help oncologic surgeons to perform this challenging procedure.
