Open versus laparoscopic portal lymphadenectomy in gallbladder cancer: is there a difference in lymph node yield?

In this analysis of national data, LN yield following laparoscopic resection for GBC was significantly lower than following open resection. Open resection is more frequently performed at academic centers, possibly to assure adequate oncologic resection. Enforcing consensus guidelines for lymphadenectomy in gallbladder cancer will optimize outcomes as minimally invasive approaches evolve.
