Clinical implication of surgical resection for recurrent biliary tract cancer: Does it work or not?

Although recent advances in imaging diagnosis, surgical techniques, and perioperative management can result in increased resectability and improved surgical outcomes, most resected patients still develop cancer recurrence. If patients develop cancer recurrence, their prognosis is very ominous. However, there have been some recent reports to show promising outcomes by aggressive surgical strategy in selected patients who developed cancer recurrence. Because there are various surgical procedures being selected at initial surgery in patients with biliary tract cancers, recurrent patterns after resection are very variable in each patient. However, surgical procedures might usually be very complicated and difficult if re‐surgical resection is considered in patients with recurrent biliary tract cancer, Therefore, surgical re‐resection could bring about high surgical morbidity and mortality rates in most previously reported series. Although re‐surgical resection might offer a chance of favorable outcome in selected patients with biliary tract cancers, these aggressive surgical approaches should be carried out in strictly selected patients by expert surgeons at high‐volume centers.
