Refining the technique of hepatic parenchymal transection: combined saline-linked radiofrequency precoagulation and ultrasonic aspiration.
OBJECTIVE
With recognition of its benefits, there has been a trend towards minimizing blood loss during hepatic parenchymal transection but no one technique has been shown to be superior to another. We analyzed our experience with using a novel combined technique of saline-linked radiofrequency precoagulation and ultrasonic aspiration for hepatic parenchymal transection.


METHODS
This combined technique was used in 12 patients for parenchymal transection for metastatic hepatic disease and data was collected prospectively. Total blood loss, bile leaks, parenchymal transection time, hepatic pedicle clamp requirement and 30-day mortality were used as outcome measures.


RESULTS
Four minor and 8 major hepatic resections were performed in twelve patients of who two underwent a synchronous resection of the rectum. The median blood loss was 525 mL (IQR 312.5-1150) in these patients who had a median postoperative stay of 7 days (IQR 7-14). The median parenchymal transection time was 120 minutes (IQR 100-153.75). No patient required portal triad clamping at anytime and there was no mortality.


CONCLUSIONS
Combined technique of saline-link radiofrequency ablation and ultrasonic aspiration appears to be comparable to other techniques and should be considered as an alternative.
