A patient with huge HCC who underwent repair of diaphragm with a right external oblique muscle because of combined resection is reported. The postoperative course was uneventful, including respiratory function. Combined resection of the diaphragm is sometimes necessary for the resection of HCC. Most defects are closed primarily. However, in patients with a large defect, reconstruction is necessary. In such cases two types of material are available: artificial materials like Teflon and biomaterials (external oblique muscle, latissumus dorsi muscle, etc). Compared with artificial materials, bio-materials have decreased risks of infection, abscess at the liver stump and so on. Among several bio-materials we prefer to use the external obilique muscle, because of the ease of making a muscle flap and repairing the diaphragm in the same operation field used for resection. Considering these advantages, repair of the diaphragm with the external oblique muscle is a useful method of surgery for huge HCC invading the diaphragm.
