Tumor location of extrahepatic CCA does not independently predict cancer-specific survival after resection. We developed a nomogram, based on a prognostic model with lymph node status, microscopically residual tumor status of resection margins, and tumor differentiation grade, that predicted survival better than TNM staging.

Reviewing our results and the available literature, we believe that the outcome of surgery during pregnancy is not dictated by the type of procedure but by the type of disease. The gain for fetal outcome in the future most likely lies in the diagnostic pathway rather than the type of surgery.

A “swirl sign” on computerized tomography is an indicator of internal herniation through Petersen’s space and should prompt immediate diagnostic laparoscopy in patients following laparoscopic Roux-en-Y gastric bypass.

Clinical judgment of residual disease after primary cytoreductive surgery in patients with advanced-stage EOC shows limited accuracy. Given the poor interobserver reproducibility, prediction models could attribute to uniform treatment decisions and improve counseling.
