    Notizen: Abstract In this study, the risk factors related to intraperitoneal septic complications occurring after hepatectomy (IPSCH) as well as the effect of various perioperative variables on the outcome of IPSCH between 1985 and 1990 were analyzed. Twenty-one of 211 patients (10.0%) developed IPSCH. The findings in the patients with IPSCH were compared with those in 190 patients without IPSCH. The significant variables associated with the development of IPSCH included a high incidence of accompanying chronic renal failure (14.3% vs 2.1%), a larger blood loss during surgery (2,130 vs 1,340 ml) as well as a greater amount of intraoperative blood replacement (1,130 vs 570 ml), and a greater weight of the resected liver (367 vs 233g). IPSCH occurred in 10 of 12 patients who had postoperative bile leakage. Eighteen patients (85.7%) with IPSCH were discharged from the hospital after non-operative management; however, the hospital death rate (14.3% vs 1.1%) was significantly higher in patients with IPSCH. This review suggests that the incidence of IPSCH has not decreased recently. Thus, to prevent IPSCH, at least following bile leakage, it is necessary to perform a careful division of the liver parenchyma followed by a bile leakage test, and when this complication occurs unexpectedly in patients who have a good functional reserve of the remnant liver, IPSCH can be effectively drained percutaneously under ultrasound guidance.

    Notizen: Abstract The regenerative capacity of the liver was assessed using a volumetric method on computed tomography in 21 adults: 16 underwent a standard right hepatic lobectomy for hepatocellular carcinoma, there were hepatic metastases in 3 others, and 2 suffered from other diseases. The patients' ages ranged from 33 to 68 years with a mean age of 57.0 years. The regeneration rate was expressed as the rate of the volume increase of the remnant left lobe compared with the preoperative volume of the left lobe. A univariate regression analysis showed that the portal pressure had a highly inverse correlation with the regeneration rate of the liver (r = −0.4753,P = 0.0397), while a multiple regression analysis demonstrated the correlation between the portal pressure, age, and the regeneration rate (multipler = 0.5640). The regeneration rate of the normal liver (97.6 ± 53.5%) was significantly higher than that of the chronic hepatitic (43.0 ± 40.7%), and also tended to be higher than that of the cirrhotic liver (51.5 ± 13.2%). However, there were no differences between chronic hepatitic and cirrhotic livers. The portal pressure before hepatectomy of the normal liver (149 ± 19 mmH2O) was significantly lower than those of chronic hepatitic (188 ± 38 mmH2O) and cirrhotic (245 ±78 mmH2O) livers. We thus conclude that the regenerative capacity of the liver following a right hepatic lobectomy could be estimated on the basis of both portal pressure and age. The regenerative capacity was also influenced by underlying liver diseases.

    Notizen: Abstract A retrospective analysis was made of 58 patients who unexpectedly developed multiple organ failure (MOF) following elective surgery, and the results were compared with those of 168 control patients who did not develop MOF. In 33 patients with liver cirrhosis, MOF was related to poor liver function, a low albumin level, excessive blood loss, many transfusions, and a high incidence of hypotension. MOF, rather than liver failure alone, was featured by postoperative bleeding and infection. In 15 patients with esophageal carcinoma, MOF was correlated with many transfusions, anastomotic leakage, and postoperative infection. In 10 patients who underwent surgery for an aortic aneurysm, poor renal function and extended anesthesia time were associated with MOF. These results indicate that to prevent MOF following elective surgery, it is important to: (1) Select patients for liver surgery according to their liver function, and minimize the risk of bleeding and infection, (2) avoid too many blood transfusions, and minimize the risk of leakage and infection in esophageal surgery, and (3) select patients for aortic surgery based on renal function and reduce the anesthesia time as much as possible.

    Notizen: Abstract The capabilities of computed tomography (CT), ultrasonography (US), and magnetic resonance (MR) imaging were studied in order to determine the role of each of these noninvasive examinations for estimating the T-factor of hepatocellular carcinomas (HCCs). Fifty-one patients with surgically proven HCCs received CT (50 patients), US (46 patients), and MR (44 patients). The images of CT, US, and MR were prospectively evaluated for main tumor size, intrahepatic metastases, and vascular invasion, which compose the T-factor of HCC, and compared to pathological results. The sizes of the main tumor were estimated correctly by all examinations. For estimating intrahepatic metastases, US (74%) and MR (73%) were superior to CT (65%). For estimating portal invasion, CT (79%) was superior to US (70%) and MR (66%), because CT could demonstrate the segmental staining caused by portal invasion. The estimates of hepatic venous invasion were difficult during any of the examinations. We conclude that presurgical evaluations of the T-factor require the use of US and CT or MR and CT.
