Minimally invasive surgical approach to hepatic hemangioma

There are two major minimally invasive surgical methods for hepatic hemangioma, one is laparoscopic surgery, in which several small holes of 0.5-1.5 cm are cut in the abdomen to perform resection of hemangioma, liver lobes or liver segments through special laparoscopic instruments; the other can be ablation or interventional embolization, but the effect is relatively inferior. Interventional embolization is performed by inserting a guidewire through the femoral artery to the hepatic artery and the blood supplying artery of the hemangioma to embolize the blood supplying artery of the hemangioma, so that the hemangioma can slowly shrink. There is no way to achieve a cure with interventional therapy. After some vessels are blocked, a lot of collateral circulation will be re-established, so it is usually necessary to repeat interventional therapy several times, which is to inhibit the growth rate of hemangioma and let it shrink slowly. Ablation is an interventional technique that uses electrode catheters delivered through veins and arteries to specific locations in the liver, and then releases an electric current to cause coagulation and necrosis of the diseased tissue. The most important feature of radiofrequency ablation is that it is relatively simple to operate and has a high safety factor. The best treatment is still surgical excision.
