Abstract
The nuances of determining resectability for liver tumors can be difficult to navigate, owing to the variety of primary and secondary malignancies involving the liver, the range of patient-specific factors to consider, and the hepatic anatomic and functional variability that seems inevitable. The basic principles, however, are simple;if surgery is deemed appropriate from an oncologic standpoint, the patient is in reasonably good health, and the tumor can be safely removed without compromising the integrity of the future remnant, nearly all patients will be candidates for resection.

Abstract
AIMS Staging laparoscopy has been recommended in the management of patients with colorectal liver metastases prior to hepatectomy in order to reduce the incidence and associated morbidity of futile laparotomies. The utility of staging laparoscopy has not been assessed in patients undergoing CT, PET-CT and MRI as standard preoperative staging. METHODS All patients undergoing attempted open hepatectomy for colorectal liver metastases between 1/4/2008 and 31/3/2012 were identified from a prospectively maintained research database. All patients who underwent futile laparotomy were identified, with demographics and operative notes subsequently analysed. RESULTS A total of 274 patients underwent attempted open hepatectomy during the study period. At laparotomy 12 (4.4%) patients were found to have irresectable disease. There were no unifying demographic factors within the patients undergoing futile laparotomy. CONCLUSIONS With modern imaging, the potential yield of staging laparoscopy is low. Staging laparoscopy should not be used routinely, but may have a role in the case of specific clinical concerns.

Abstract
INTRODUCTION Traditionally, rates of irresectable disease at laparotomy for colorectal liver metastases (CRLM) have ranged from 15 to 70%. Diagnostic laparoscopy has been shown to be effective at preventing nontherapeutic laparotomy in selected patients. The purpose of this study was to analyze the resectability rate and role of diagnostic laparoscopy in a contemporary cohort. METHODS Using a prospectively maintained database, we identified patients who were explored for presumed resectable CRLM. Clinical and pathologic data associated with the finding of irresectable disease were analyzed. RESULTS From 2008-2010, 455 patients were explored. Of these, 35 (7.7%) did not undergo a resection and/or ablation. Of the 35 patients with irresectable disease, 15 (43%) had disease limited to the liver, 17 (49%) had extrahepatic disease (EHD), and 3 (9%) had other reasons precluding resection. Of the whole cohort, 45 patients (9.9%) were found to have EHD, and 27 of these (60%) underwent complete resection or ablation. The only factor associated with irresectable disease was a prior history of EHD, which was present in 29% of those found irresectable versus 13% of those resected (p = 0.022). Diagnostic laparoscopy was performed in 55 patients. Four of these patients had irresectable disease, and three were spared unnecessary laparotomy. Therefore, the yield was 5% and the sensitivity 75%. CONCLUSIONS The finding of irresectable disease is a rare event with modern radiologic assessment and the expansion of indications for resection. Diagnostic laparoscopy has a low yield and should be considered if there is a history of EHD or suspicious findings on preoperative imaging.

The role of laparoscopy and laparoscopic ultrasound in the preoperative staging of patients with resectable colorectal liver metastases: a meta-analysis. Am J Surg 2012; 204:84-92.

Abstract
BACKGROUND The role of staging laparoscopy (SL) with laparoscopic ultrasound (LUS) in patients with resectable colorectal liver metastases (CRLM) remains controversial. METHODS A meta-analysis of all studies (from 1998 to the present) on the effect of SL/LUS in patients with potentially resectable CRLM with respect to alteration in surgical management was performed. RESULTS Twelve studies satisfied the inclusion criteria. A total of 1,047 patients underwent SL/LUS. The true yield of SL/LUS for CRLM was 19% (95% confidence interval [CI], 16%-22%), with a diagnostic odds ratio of 132 (95% CI, 56-310) and an overall sensitivity of 59% (95% CI, 53%-65%). Subgroup analysis for detection of other liver and peritoneal lesions showed a sensitivity of 59% (95% CI, 49%-67%) and 75% (95% CI, 63%-85%) respectively. There was major between-study heterogeneity for all analyses, with no obvious cause revealed by meta-regression. CONCLUSIONS The true benefit of using SL/LUS universally seems limited. It appears more useful as an adjunct in patients when peritoneal disease is suspected.

Abstract
PURPOSE Prognosis after resection of liver metastases of colorectal cancer is influenced by a variety of clinical factors. For more than 20 years, efforts have been made to restructure and simplify prognostic parameters into clinical scores. We evaluated the influence of various clinical and pathological factors on survival and recurrence and developed a simple model for risk stratification. METHODS We have analyzed a total of 13 prognostic factors in 382 consecutive and prospectively enrolled R0-resected patients and applied our data set to ten published prognostic scoring systems. Prognostic factors that influenced disease-specific and disease-free survival were included into a model clinical risk score. RESULTS The 5- and 10-year observed survival rates were 43% and 28%, respectively, for all 382 patients. The disease-specific 5- and 10-year survival rates were 49% and 37%, respectively; the 5- and 10-year recurrence rates were 68% and 70%, respectively. For patients with synchronous liver metastases, survival was not affected by the timing of liver resection. The prognosis after treatment of any recurrence was best after the accomplishment of a repeated R0 situation, independent of the location of the recurrence. In the multivariate analysis, the disease-specific survival and recurrence rates were statistically significantly influenced by more than three lymph node metastases of the primary tumor, more than two lesions within the liver, and the presence of extrahepatic tumor. CONCLUSIONS From these data, we have developed a simple score for the risk stratification which may be useful for future studies on interdisciplinary management of colorectal liver metastases.

Abstract
Up to 50% of patients with colorectal cancer will develop metastatic disease in the liver. While surgical extirpation remains the best option for long-term survival, several complementary modalities such as laparoscopy, radiofrequency ablation, and microwave coagulation have gained wide acceptance as primary and adjunct therapies for both resectable and unresectable disease. This review will focus on the application and outcome of these techniques in patients with colorectal liver metastases.

Abstract
OBJECTIVE [F-18]-Fluorodeoxyglucose-positron emission tomography (FDG-PET) is used increasingly in the work-up to surgery for patients with potentially resectable colorectal liver metastases. This study evaluates the clinical effectiveness, impact on health care resources and cost-effectiveness of adding FDG-PET to the diagnostic algorithm alongside a randomized clinical trial from a health care perspective. METHODS In a randomized clinical trial, the net monetary benefit (NMB) of FDG-PET added to conventional diagnostic work-up (CWU) was determined in patients with colorectal liver metastases. Seventy-five patients were included in each arm. Change in clinical management, futile laparotomies, preoperative findings and all relevant health care consumption were prospectively documented during 3 years. To assess health-related quality of life European Quality of Life-5 Dimensions was administered at the time of randomization, 3 and 6 weeks postoperatively, and every 3 months postoperatively for 3 years. Quality-adjusted life years (QALYs) were calculated based on European Quality of Life-5 Dimensions outcomes. RESULTS In adding FDG-PET, diagnostic performance increased and futile laparotomies were reduced by 38%. Both health-related quality of life and QALYs showed no significant difference between the CWU and PET groups. For CWU and PET groups costs were euro 92,836 and euro 81,776, respectively, accumulated in 3 years after randomization. NMB ranged from euro 1004 to euro 11,060 depending on the monetary value given to a QALY. When costs for chemotherapy were disregarded, costs amounted to euro 15,874 for CWU and euro 18,664 for PET group. CONCLUSION Additional costs of FDG-PET in the diagnostic work-up of patients with potentially resectable colorectal liver metastases were compensated by a reduction in futile laparotomies. The NMB analysis showed savings over a relevant range of willingness to pay for a QALY.

Abstract
Even after extensive preoperative assessment, staging laparoscopy may allow avoidance of non-therapeutic laparotomy in patients with radiographically occult metastatic or locally unresectable disease. Staging laparoscopy is associated with decreased postoperative pain, a shorter hospital stay and a higher likelihood of receiving systemic therapy compared to laparotomy but its yield has decreased with improvements in imaging techniques. Current uses of staging laparoscopy include the following: (1) In the staging of pancreatic adenocarcinoma, laparoscopic staging allows for the identification of sub-radiographic metastatic disease in locally advanced cancer in approximately 30% of patients and, in radiographically resectable cancer, may identify metastatic disease in 10%-15% of cases; (2) In colorectal liver metastases, selective use of laparoscopic staging in patients with a clinical risk score of over 2 identifies unresectable disease in approximately 20% of patients; (3) In hepatocellular carcinoma, laparoscopic staging could be selectively used in high-risk patients such as those with clinically apparent liver cirrhosis and in patients with major vascular invasion or bilobar tumors; and (4) In biliary tract malignancy, staging laparoscopy may be used in all patients with potentially resectable primary gallbladder cancer and in selected patients with T2/T3 hilar cholangiocarcinoma. Because of the decreasing yield of SL secondary to improvements in imaging techniques, staging laparoscopy should be used selectively for patients with pancreatic and hepatobiliary malignancy to avoid unnecessary non-therapeutic laparotomy and to improve resource utilization. Each individual surgeon should apply his or her threshold as to whether staging laparoscopy is indicated according to the quality of preoperative imaging studies and the availability of resources at their own institution.

Abstract
AIM Laparoscopy is an increasingly important tool in the staging and treatment for potentially resectable liver metastases. The clinical risk score (CRS) is useful in selecting patients for diagnostic laparoscopy before planning resection of colorectal metastases. This study evaluates the effect of staging laparoscopy (SL) combined with CRS. MATERIALS AND METHODS From January 2004 to December 2007, CRS evaluation and SL were performed in 65 consecutive patients with colorectal metastases, before planned open-exploration and resection. Patients were assigned to a CRS, which is based on 5 factors related to the primary tumor and the hepatic disease. This study was aimed at recognizing occult unresectable metastases, by combining laparoscopy and CRS. RESULTS Only 62 patients had a complete SL examination (3 were excluded for dense adhesions). A group of 24 patients was identified as unresectable, and 38 patients as resectable. In the latter group, 3 patients directly had laparoscopic treatment. In all, 38 patients underwent laparotomy (35 resectable, and 3 patients with dense adhesions that could not have a complete laparoscopic treatment).Resection was carried out in 30 of 38 (78.9%) cases, and the remaining 21% gave false-negative results. In all, there were 32 of 65 (49.2%) unresectable patients, and 75% of them were recognized by SL. CONCLUSIONS Laparoscopy identified the majority of patients with occult unresectable disease, improved resectability, and it should be a routine in patients being considered for potentially curative hepatic resection. The CRS, earlier shown to predict survival after hepatic resection, identifies high-risk patients, who are most likely to benefit from laparoscopy, and may improve resource utilization.

Abstract
BACKGROUND The aim of this study was to compare the risk scores of Fong et al., Nordlinger et al., and the TNM classification of colorectal liver metastases proposed by the UICC. METHODS Data from 282 consecutive patients undergoing 303 liver resections for metastatic colorectal cancer between 1995 and 2006 at the Department of Surgery, University of Erlangen were analyzed. The median follow-up time was 34 months. A curative (R0) resection was performed in 92% of the patients. RESULTS Applying the clinical risk score of Fong with preoperative data identified three risk groups. The survival rates between "low risk" (n = 22) and "intermediate risk" (n = 222) diverged (P = 0.073). The survival rates between "intermediate risk" and "high risk" (n = 59) differed significantly (P = 0.030). Using the risk scoring system of Nordlinger, patients were divided into two risk groups (i.e., "low risk" (n = 218) and "intermediate risk" (n = 68)). Significant differences in survival between the groups were noted (P = 0.012). Applying the clinical TNM classification of colorectal liver metastases revealed no significant differences in survival between the risk groups. CONCLUSIONS Our study found the clinical risk score developed by Fong et al. to be a reliable preoperative prognostic tool for selecting patients for surgical resection of colorectal liver metastases.

Abstract
BACKGROUND AND AIMS Right portal vein ligation (PVL) has its recognized role in inducing hypertrophy of future liver remnant (FLR) prior to major liver resection. The aim of this study was to evaluate the safety, feasibility, and effectiveness of laparoscopic right PVL and to explore its applications. METHODS Laparoscopic right PVL was employed either during staging laparoscopy when a right hepatic trisectionectomy was indicated, leaving a small (<25%) FLR (indication 1), or during a laparoscopic left hepatic lobectomy (left lateral sectionectomy) when a second-stage right hemihepatectomy was to follow (indication 2). A follow up cross-sectional liver imaging was performed 4-6 weeks later with liver volumetry to confirm hypertrophy of the FLR before proceeding to major hepatectomy. RESULTS Six patients (female, 5), 74-83 years old, underwent a laparoscopic right PVL, of whom 4 patients fulfilled indication 1 while 2 patients fulfilled indication 2. The median operating time for indication 1 was 60 minutes. There were no intra- or postoperative complications, and all procedures were completed laparoscopically. Repeat imaging of the liver demonstrated a median (range) hypertrophy of FLR of 24.5% (range, 20.7-33.1%). The right liver experienced atrophy. CONCLUSIONS In the hands of the experienced laparoscopic hepatobiliary surgeon, laparoscopic right PVL is feasible and safe, and induces adequate regeneration of the FLR. Laparoscopic right PVL has its applications at the time of staging laparoscopy in patients requiring a right hepatic trisectionectomy in the presence of a small FLR and as part of a staged liver resection in patients with bilobar liver disease that spares segments 1 and 4.

Abstract
UNLABELLED With the increasing possibilities for surgical treatment of colorectal liver metastases, careful selection of patients who may benefit from surgical treatment becomes critical. The addition of PET to (18)F-FDG may significantly improve conventional staging by CT. Up to now, definitive evidence that the addition of (18)F-FDG PET to conventional staging leads to superior clinical results and improved clinical management in these patients has been lacking. In this randomized controlled trial in patients with colorectal liver metastases, we investigated whether the addition of (18)F-FDG PET is beneficial and reduces the number of futile laparotomies. METHODS A total of 150 patients with colorectal liver metastases selected for surgical treatment by imaging with CT were randomly assigned to CT only (n = 75) or CT plus (18)F-FDG PET (n = 75). Patients were followed up for at least 3 y. The primary outcome measure was futile laparotomy, defined as any laparotomy that did not result in complete tumor treatment, that revealed benign disease, or that did not result in a disease-free survival period longer than 6 mo. RESULTS Patient and tumor characteristics were similar for both groups. The number of futile laparotomies was 34 (45%) in the control arm without (18)F-FDG PET and 21 (28%) in the experimental arm with (18)F-FDG PET; the relative risk reduction was 38% (95% confidence interval, 4%-60%, P = 0.042). CONCLUSION The number of futile laparotomies was reduced from 45% to 28%; thus, the addition of (18)F-FDG PET to the work-up for surgical resection of colorectal liver metastases prevents unnecessary surgery in 1 of 6 patients.

Abstract
Surgery is the treatment of choice in selected patients with hepatic colorectal metastases. Despite improvements in preoperative imaging, patients can undergo unnecessary nontherapeutic laparotomy. The aim of this study was to examine trends in nontherapeutic laparotomy rates in patients undergoing planned surgical therapy for hepatic colorectal metastases. Data from 530 operations (461 patients) undergoing potentially curative surgical therapy for colorectal liver metastases between 1994 and 2005 were analyzed. The incidence of nontherapeutic laparotomy was determined and factors associated with nontherapeutic laparotomy were identified. Overall, 49 nontherapeutic laparotomies were performed (9.2%). Higher nontherapeutic laparotomy rates were seen in patients with multiple metastases and tumor size >5 cm (both P < 0.05). Preoperative positron emission tomography (PET) imaging was associated with lower risk of nontherapeutic laparotomy [5.6% versus 12.4%, P = 0.009, odds ratio (OR) = 0.42]. At laparotomy, extrahepatic findings were the reason for nontherapeutic laparotomy in 44.9% of cases. The nontherapeutic laparotomy rate significantly decreased over time (14.9% for 1994-1997 versus 9.6% for 1998-2001 versus 4.7% for 2002-2005; P = 0.003). While patients in each time period were similar with regard to tumor specific factors, utilization of PET imaging (P < 0.001) as well as resection plus ablation (P = 0.004) increased over time. We conclude that prevalence of nontherapeutic laparotomy for patients undergoing surgical exploration for hepatic colorectal metastases has decreased significantly in recent years to less than 5%. The reasons for this trend are probably multifactorial and may include improved preoperative assessment, such as PET imaging, as well as salvage surgical options.

A subset of patients undergo laparoscopic intervention prior to PVE for staging purposes or to address the primary in Stage IV colon cancer. These patients usually undergo PVE as a subsequent additional procedure by the transhepatic route. The aim of this study was to assess the feasibility of portal vein ligation by the laparoscopic approach in suitable patients. MATERIALS AND METHODS A retrospective review of a prospectively maintained database was performed to identify patients that underwent laparoscopic portal vein ligation (LPVL). The demographic, clinical, radiographic, operative and volumetric details were collected to determine the feasibility of portal vein ligation. RESULTS A total of nine patients underwent LPVL as part of a two stage procedure in preparation for subsequent major hepatectomy. With a median age of 67 yrs, the diagnoses included: colorectal metastasis (five patients), cholangiocarcinoma (three patients) and hepatocellular carcinoma (one patient). The ligation involved the right portal vein in all and was performed with silk ligature (seven patients) and clips (two patients). Volumetric data was available in six patients which showed a mean increase from 209.1 cc+/-97.76 to 495.83 cc+/-310.91 (increase by 181.5%) In two patients, inadequate hypertrophy mandated later embolization by percutaneous technique. Five patients underwent subsequent major hepatic resection as planned. The remaining four patients were noted to have progression of disease that precluded the planned procedure. There were no complications associated with LPVL. CONCLUSIONS LPVL is feasible and can be safely performed. In a select group of patients, it may be considered as an alternative to subsequent embolization and thereby potentially absolve the need for an additional procedure with its attendant complications.

Abstract
BACKGROUND AND AIMS The aim of this retrospective study was to establish whether Fong's risk score can predict rate of resectability and whether laparoscopic exploration with ultrasonography can reduce the number of useless laparotomies to any extent. MATERIAL AND METHODS Fong's score was calculated for each of the 43 potential resectable patients. We analysed: the relation between score and resectability; the probability of unnecessary laparotomy with respect to each level of score; and which of the five Fong parameters was the most indicative of non-resectability. None of our patients was submitted to preoperative laparoscopic staging. RESULTS All patients with Fong's score 0 were submitted to liver resection, whereas only 76.9% with score 1, 58.3% with score 2, and 66.6% with score 3. No patients had score 4 and 5. "CEA level" is the parameter that best predicts the "non-resectability" of metastases. In the subgroup with score 0-1, laparoscopy would have spared 12% of unnecessary laparotomies, whereas in subgroup 2-3 this percentage would have risen to 38.9. CONCLUSIONS The above data allowed us to quantify statistically the risk associated with non-resectability of liver metastases in a directly proportional manner as the score progresses.
