Laparoscopic Resection of Hilar Cholangiocarcinoma

Background: Surgical resection is the only curative treatment for hilar cholangiocarcinoma. Laparoscopic hepatectomy has been used to treat several types of liver neoplasms. However, technical issues have limited the adoption of laparoscopy for the treatment of hilar cholangiocarcinoma. To date there is only one report of minimally invasive procedure for hilar cholangiocarcinoma in the literature. The present video-assisted procedure shows a laparoscopic resection of hilar cholangiocarcinoma. Patient and Methods: A 43-year-old woman with progressive jaundice due to left-sided hilar cholangiocarcinoma was referred for treatment. The decision was to perform a laparoscopic left hepatectomy with lymphadenectomy and resection of extrahepatic bile ducts. Biliary reconstruction was performed using the hybrid method. Results: Operative time was 300 minutes with minimum blood loss and no need for blood transfusion. Recovery was uneventful, and the patient was discharged on postoperative Day 7. Pathology revealed a well-differentiated cholangiocarcinoma with negative lymph nodes and clear surgical margins. The patient is well with no signs of the disease 18 months after the procedure. Conclusions: Laparoscopic left hepatectomy with lymphadenectomy is safe and feasible in selected patients and when performed by surgeons with expertise in liver surgery and minimally invasive techniques. The use of a hybrid method may be needed for biliary reconstruction, especially in cases where position and size of remnant bile ducts may jeopardize the anastomosis. Further studies are still needed to confirm the benefit of this approach over conventional surgery for hilar cholangiocarcinoma.

Biliary tract schwannoma: A rare cause of obstructive jaundice in a young patient

Schwannoma is a tumor derived from Schwann cells which usually arises in the upper extremities, trunk, head and neck, retroperitoneum, mediastinum, pelvis, and peritoneum. However, it can arise in the gastrointestinal tract, including biliary tract. We present a 24-year-old male patient with obstructive jaundice, whose investigation with computed tomography abdomen showed focal wall thickening in the common hepatic duct, difficult to differentiate with hilar adenocarcinoma. He was diagnosed intraoperatively schwannoma of common bile duct and treated with local resection. The patient recovered well without signs of recurrence of the lesion after 12 mo. We also reviewed the common bile duct schwannoma related in the literature and evaluated the difficulty in pre and intraoperative differential diagnosis with adenocarcinoma hilar. Resection is the treatment of choice for such cases and the tumor did not recur in any of the resected cases. (C) 2012 Baishideng. All rights reserved.
