Severity of disease as main predictor for mortality in patients with pyogenic liver abscess

Background

The purpose of this study was to explore the relationship between severity of illness at admission and mortality of patients with pyogenic liver abscess (PLA).

Methods

Medical records from 298 PLA patients ≥18 years old were reviewed. Severity of illness at admission was evaluated with the Acute Physiology and Chronic Health Evaluation (APACHE) II and the simplified acute physiology score (SAPS) II scoring systems. Stepwise logistic regression and receiver-operating-characteristic curve analyses were performed.

Results

The case-fatality rate was 10%. Multivariate analysis showed that APACHE II (P = .0004), SAPS II (P = .0008), the presence of gas-forming abscess (P <.0001), and the presence of anaerobic infection (P <.0001) all were associated with mortality. The area under the receiver-operating-characteristic curve was .884 (95% confidence interval .842 to .918) for APACHE II and .857 (95% confidence interval .812 to .895) for SAPS II, which were not significantly different (P = .490). The optimal cutoff APACHE II value of ≥15 had a sensitivity of 77% and a specificity of 92%, with a 20.3-fold risk of mortality (P <.0001). The SAPS II cutoff value of ≥28 had a sensitivity of 74% and a specificity of 82%, with a 7.2-fold risk of mortality (P = .008).

Conclusions

Both the APACHE II and the SAPS II scoring methods are appropriate for assessing mortality of PLA patients.

Preparatory hepatic resection with right hepatic vein reconstruction for paracaval liver tumor

A liver tumor in the paracaval portion was very difficult to resect because of its anatomical situation. We therefore employed a technique using right hepatic vein (RHV) resection and reconstruction following the resection of segments VII/VIII with the paracaval portion. The patient was a 70-year-old man who had a hepatocellular carcinoma in the paracaval portion, and the root of the RHV was compressed by the tumor. Computed tomography (CT) during arterioportography under temporary balloon occlusion of the RHV demonstrated hypoattenuation of the entire posterior segment, meaning that RHV reconstruction following the resection of segments VII/VIII with RHV resection would be necessary. We performed the above-mentioned operation without any trouble. On mobilizing segments VI/V to the caudal direction after dissecting the distal RHV, the paracaval Glissons were easily exposed and dissected anteriorly from the first order of the right Glissonean sheath. Our preliminary surgical technique, based on IVR-CT, could provide a better surgical field and result in decreased operating time and decreased blood loss in paracaval liver malignancy.

Volumetric analysis predicts hepatic dysfunction in patients undergoing major liver resection

Liver-enhancing modalities, such as portal vein embolization, are increasingly employed prior to major liver resection to prevent postoperative liver dysfunction. Selection criteria for such techniques are not well described. This study uses CT-based volumetric analysis as a tool to identify patients at highest risk for postoperative hepatic dysfunction. Between July 1999 and December 2000, a total of 126 consecutive patients who were undergoing liver resection for colorectal metastasis and had CT scans at our institution were included in the analysis. Volume of resection was determined by semiautomated contouring of the liver on preoperative volumetrically (helical) acquired CT scans. Hepatic dysfunction was defined as prothrombin time greater than 18 seconds or serum bilirubin level greater than 3 mg/dl. Marginal regression was used to compare the predictive ability of volumetric analysis and the extent of resection. The percentage of liver remaining was closely correlated with increasing prothrombin time and bilirubin level (P < 0.001). After trisegmentectomy, 90% of patients with ≤s25% of liver remaining developed hepatic dysfunction, compared with none of the patients with more than 25% of liver remaining after trisegmentectomy (P < 0.0001). The percentage of liver remaining was more specific in predicting hepatic dysfunction than was the anatomic extent of resection (P = 0.003). Male sex nearly doubled the risk of hepatic dysfunction (odds ratio = 1.89, P = 0.027), and having ≤25% of liver remaining more than tripled the risk (odds ratio = 3.09, P < 0.0001). Hepatic dysfunction and ≤25% of liver remaining were associated with increased complications and length of hospital stay (P < 0.0001 and P = 0.0003, respectively). Preoperative assessment of future liver volume remaining distinguishes which patients undergoing liver resection will most likely benefit from preoperative liver enhancement techniques such as portal vein embolization.

Repeat hepatic resection as effective treatment for recurrent colorectal liver metastases

Background: Approximately 20–40% of patients who undergo liver resection for colorectal metastases develop recurrent disease confined to the liver. The goals of this study were to determine whether the survival benefit of repeat hepatic resection justified the potential morbidity and mortality. Methods: A retrospective review was performed on all patients who underwent liver resection for colorectal cancer metastases between 1983 and 1995 (N=202). Repeat liver resections were performed on 23 patients for recurrent metastases. Results: There were no operative deaths in the 23 patients, and the postoperative morbidity rate was 22%. The 5-year actuarial survival rate after repeat resection was 32%, with a median length of survival of 39.9 months. There were three patients who survived for >5 years after repeat resection. Sixteen patients (70%) developed recurrent disease at a median interval of 11 months after the second resection; 10 of these 16 patients (62%) had new hepatic metastases. No clinical or pathological factors were significant in predicting long-term survival. Conclusions: Repeat liver resection for recurrent colorectal metastases (a) can be performed safely with acceptable mortality and morbidity rates and (b) may result in long-term survival in some patients.Presented at the 49th Annual Cancer Symposium of The Society of Surgical Oncology, Atlanta, Georgia, March 21–24, 1996.     

A new scoring system to classify patients with colorectal liver metastases: proposal of criteria to select candidates for hepatic resection

Background Although many studies have reported the beneficial effects of hepatic resection for colorectal liver metastases on survival rates, it is still difficult to preoperatively select good candidates for hepatectomy.Methods Fifteen clinicopathological features, which were recognized only before or during surgery, were selected retrospectively in 81 consecutive patients in one hospital (Group I). These features were entered into a multivariate analysis to determine independent and significant variables affecting long-term prognosis after hepatectomy. Using selected variables, we created a scoring formula to classify patients with colorectal liver metastases to select good candidates for hepatic resection. The usefulness of the new scoring system was examined in a series of 70 patients from another hospital (Group II).Results Multivariate analysis, i.e., Cox regression analysis, showed that serosa invasion of primary cancers (P = 0.0720, risk ratio = 2.238); local lymph node metastases of primary cancers, i.e., Dukes C (P = 0.0976, risk ratio = 2.311); multiple nodules of hepatic metastases (P = 0.0461, risk ratio = 2.365); nodules of hepatic metastases greater than 5cm in diameter (P =0.0030, risk ratio = 4.277); and resectable extrahepatic distant metastases (P = 0.0080, risk ratio = 4.038) were significant and independent prognostic factors for poor survival after hepatectomy. Using thsee five variables, we created a new scoring formula to classify patients with colorectal liver metastases. Finally, our new scoring system classified patients in Group II and Group I well, according to long-term outcomes after hepatic resection.Conclusions Our new scoring system to classify patients with colorectal liver metastases is simple and useful in the preoperative selection of good candidates for hepatic resection.     

The development of a pyogenic liver abscess following radical resection of cholangiocellular carcinoma with ligation of the right hepatic artery: Report of a case

We present herein the case of a pyogenic liver abscess developing from hepatic ischemia caused by resection of the right hepatic artery when a left hemihepatectomy with caudate lobectomy and extrahepatic bile duct resection was performed for cholangiocellular carcinoma. Postoperative cholangiography revealed communication between the abscess cavity and the intrahepatic bile duct. The liver abscess was successfully treated by percutaneous transhepatic drainage. Thus, breakdown of the intrahepatic bile duct due to ischemia may play an important role in the development of a pyogenic liver abscess following hepatic arterial occlusion.     

Long-term outcomes after hepatic resection combined with radiofrequency ablation for initially unresectable multiple and bilobar liver malignancies

Background

Hepatic resection (HRE) combined with radiofrequency ablation (RFA) offers a surgical option to a group of patients with multiple and bilobar liver malignancies who are traditionally unresectable for inadequate functional hepatic reserve. The aims of the present study were to assess the perioperative outcomes, recurrence, and long-term survival rates for patients treated with HRE plus RFA in the management of primary hepatocellular carcinoma (HCC) and metastatic liver cancer (MLC).

Methods

Data from all consecutive patients with primary and secondary hepatic malignancies who were treated with HRE combined with RFA between 2007 and 2013 were prospectively collected and retrospectively reviewed.

Results

A total of 112 patients, with 368 hepatic tumors underwent HRE combined with ultrasound-guided RFA, were included in the present study. There were 40 cases of HCC with 117 tumors and 72 cases of MLC with 251 metastases. Most cases of liver metastases originated from the gastrointestinal tract (44, 61.1%). Other uncommon lesions included breast cancer (5, 6.9%), pancreatic cancer (3, 4.2%), lung cancer (4, 5.6%), cholangiocarcinoma (4, 5.6%), and so on. The ablation success rates were 93.3% for HCC and 96.7% for MLC. The 1-, 2-, 3-, 4-, and 5-y overall recurrence rates were 52.5%, 59.5%, 72.3%, 75%, and 80% for the HCC group and 44.4%, 52.7%, 56.1%, 69.4%, and 77.8% for the MLC group, respectively. The 1-, 2-, 3-, 4-, and 5-y overall survival rates for the HCC patients were 67.5%, 50%, 32.5%, 22.5%, and 12.5% and for the MLC patients were 66.5%, 55.5%, 50%, 30.5%, and 19.4%, respectively. The corresponding recurrence-free survival rates for the HCC patients were 52.5%, 35%, 22.5%, 15%, and 10% and for the MLC patients were 58.3%, 41.6%, 23.6%, 16.9%, and 12.5%, respectively.

Conclusions

HRE combined with RFA provides an effective treatment approach for patients with primary and secondary liver malignancies who are initially unsuitable for radical resection, with high local tumor control rates and promising survival data.     

Liver resection for hepatic metastases: 15 years of experience

Background/Purpose: Liver metastases, especially those from primary colorectal cancers, are treatable and potentially curable. Imaging techniques such as computed tomography, magnetic resonance, and ultrasonography have advanced in recent years and led to increased sensitivity and specificity in the diagnosis of liver metastases. Liver surgery also has been revolutionized in the past two decades. Dissection along nonanatomical lines has permitted the resection of multiple lesions that previously might have been considered unresectable. Methods: From 1986 to 2000, 181 patients underwent liver resection for hepatic metastasis from colorectal cancer. Of these, 56 patients underwent systematic anatomical major hepatic resection and 125 underwent nonanatomical limited resection. Results: Operative morbidity and mortality rates were higher in patients in whom anatomical procedures were performed. The overall 5-year survival rate of the 181 patients was 39.8%. Conclusions: An aggressive surgical procedure in patients with hepatic colorectal metastases is safe, and may prolong overall survival, and therefore should be considered in all patients with metastases confined to the liver.

Acute generalized peritonitis in adult African patients: Assessment of severity using APACHE II score

Background: Generalized surgical acute abdomen is a significant cause of morbidity and mortality in the Nigerian environment. Severity assessment is useful in order to prioritize treatment and reduce morbidity and mortality. High severity scores are often faced with high morbidity and mortality; these patients, often require more intensive treatment than those with low severity scores. The purpose of this study was to assess the severity of generalized surgical acute abdomen in adult patients using the Acute Physiological and Chronic Ill Health Evaluation (APACHE II) score. Methods: All patients (184) aged 16 years and above, admitted and operated for generalized acute abdomen over a period of 6 years from January 1993 to December 1998 were prospectively studied. Demographic, clinical, preoperative, operative and postoperative data on each patient were entered into a prepared proforma. Severity of illness was assessed using APACHE II parameters. Postoperative outcome and severity of illness were compared to determine the significance of severity of illness on postoperative outcome. Results: Thirty‐one patients (17%) died and 78 (42.4%) developed other postoperative complications. The APACHE II scores significantly correlated with the mortality and such other postoperative complications as residual intra‐abdominal abscess, abdominal sepsis, chest infection and faecal fistula (P < 0.05) and the duration of hospital stay (P < 0.05). The APACHE II scores ranged from 0 to 18, the mean score for survivors was 5.7, while it was 12.3 for those who did not survive. Only three (4%) patients who scored 0–5 died, six (9.4%) patients who scored 6–10, 15 (50%) patients who scored 11–15 and seven patients (87.5%) died who scored 16–20. Conclusion: The study showed that the severity of generalized peritonitis can be suitably assessed by APACHE II score in our environment and may serve as means of objective assessment of the quality of care. APACHE II score predicted mortality and morbidity in the patients studied. A further study is needed involving a larger number of patients to further validate our findings. We recommend to surgeons practicing in an environment similar to ours and to use the APACHE II scoring system in the assessment of patients with acute generalized peritonitis.

Admission lactate level and the APACHE II score are the most useful predictors of prognosis following torso trauma

BACKGROUND: Markers of dysoxic metabolism and scoring systems for triage have been widely used in critically injured patients. However, so far, no model is sufficiently reliable to predict the outcome in trauma victims. The purposes of the present study, therefore, were to determine whether a correlation exits between the main trauma scoring systems and the markers of dysoxic metabolism. Moreover, to assess if any of the admission parameters can be used to indicate outcome. METHODS: Sixty-four patients were included in this study. Admission data, including arterial lactate level, base deficit (BD), pH, revised trauma score (RTS), injury severity score (ISS), shock index (SI), and Acute Physiology and Chronic Health Evaluation (APACHE II), were collected and analysed by logistic regression analysis. Degree of association between continuous variables were calculated by either Pearson's or Spearman's correlation coefficient, where applicable. The dependence of lactate on two or more other variables was evaluated by multiple linear regression analysis. RESULTS: Logistic regression analysis showed that the fatal outcome following major torso trauma was principally associated with the APACHE II score and lactate. The specificity and the sensitivity of this logistic regression model was 94.6 and 79.2%, respectively. According to standardised linear regression coefficients, BD was the best single predictor of lactate, and APACHE II added a small amount of predictive power. The proportion of total variation in lactate level explained by base deficit, APACHE II and age is R2=85.2%. CONCLUSION: APACHE II score and the arterial lactate level are the most important determinants of clinical outcome in critically injured patients. A correlation exits between lactate and APACHE II and between lactate and base deficit.     

Management of involved or close resection margins in 120 patients with colorectal liver metastases: edge cryotherapy can achieve long-term survival

BACKGROUND: The liver resection margin is prognostically significant for patients with colorectal liver metastases. Management plans for patients with suboptimal resection margins have not been adequately addressed. This article reports the long-term results of edge cryotherapy in 120 patients with suboptimal resection margins. METHODS: A retrospective analysis of prospectively collected clinical data of 120 patients with suboptimal hepatic resection margins was performed. Morbidity, mortality, recurrence, and survival results were analyzed. RESULTS: The median length follow-up was 30 months (range 1 to 139). The median disease-free interval was 19 months (range 2 to 139). Cryosite, remaining liver, and extrahepatic recurrence rates were 10%, 36%, and 47%, respectively. The median survival was 39 months (range 1 to 139), and 1-, 3-, and 5-year survival rates were 89%, 55%, and 36%, respectively. Cryosite and extrahepatic recurrence were independently associated with a reduced survival outcome. COMMENTS: Edge cryotherapy to suboptimal liver resection margins can achieve a lower local recurrence rate and a longer survival advantage.
