[Clinical application of anatomic method of separation in hepatectomy].


OBJECTIVE To investigate the effectiveness of anatomic method of separation in hepatectomy methods of decreasing postoperative complication and mortality for liver cancer patients. METHODS The clinical data of 398 patients with liver malignant tumors, admitted in our hospital during 2001 to 2007, were retrospectively analyzed. The anatomic method group (group A) included 243 contiguous patients of liver cancer who received hepatectomy by anatomical method of separation, while the traditional method group (group B) included 155 patients of liver cancer who received hepatectomy by traditional method of separation during the same period. Blood loss and transfusion during operation, postoperative liver function, complication and mortality of operation, and postoperative hospital stay were compared between these two groups. RESULTS In group A, the tumor diameters ranged (6.02 +/- 3.24) cm, the operative blood loss was (445 +/- 240) ml, and 52 patients (24.3%) underwent blood transfusion [range: (520 +/- 280) ml]. No mortality and intraabdominal hemorrhage, liver function failure, or other severe complications were noted. Only 12 patients (4.9%) suffered mild complications. The postoperative hospital stay was (13.4 +/- 4.9) days. In group B, the tumor diameters ranged (5.84 +/- 2.93 cm, the operative blood loss was (1200 +/- 320) ml, and 53 patients (34.2%) underwent transfusion [range: (1400 +/- 623) ml]. Five patients (3.23%) died within 30 days after operation. The total complication morbidity was 16.1% (25/155). Five patients suffered intraabdominal hemorrhage and 5 experienced liver function failure. Postoperative hospital stay was (18.9 +/- 10.3) days. The volume of blood loss and transfusion in group A were significantly less than in group B (P < 0.05). Mortality, severe complications, and total complication morbidity were significantly lower in group A than in group B (P < 0.05, P < 0.01). The postoperative stay was also significantly shorter in group A than in group B (P < 0.05). CONCLUSION Anatomical method of separation is an effective method of hepatectomy with relatively low complication and mortality.
