Laparoscopic liver surgery

Great advances have occurred in the field of laparoscopic hepatic surgery. It is now clear that in experienced hands, the laparoscopic method of liver resection is as safe as an open procedure. The key phrase in this last sentence is "in experienced hands". The new devices that are available might make an inexperienced hepatic surgeon, well-trained in laparoscopic surgery, embark on hepatic resection without thorough knowledge of hepatic anatomy. The converse may also be true. As no criteria for credentialing of laparoscopic hepatic surgeons exist, the decision as to who is sufficiently trained to perform these procedures is left to individual hospital credentialing boards. While a certification procedure defined by leaders in this field and supported by surgical societies would be welcomed, the ability to achieve and enforce these guidelines appear to be more of a challenge. In addition, while most comparison studies in this area conclude by suggesting that a randomized, clinical trial would be needed to definitively arrive at an answer regarding the benefits of minimally invasive liver surgery compared with open surgery, it would likely be extremely difficult to accrue patients, given the data presented in articles regarding the success of laparoscopic hepatic resections. The authors conclude that an internationalregistry of all laparoscopic cases should b e established to insure patient safety and a mechanism for self-monitoring.
