Abstract
BACKGROUND Tumor resection in non-metastatic hepatocellular carcinoma (HCC) patients with adequate liver reserve offers a potential cure, but has a high 5-year recurrence rate. We analyzed the patterns of cancer relapse after partial hepatectomy to guide post-operative management. METHODS A total of 144 HCC patients (1996-2011) after partial hepatectomy were reviewed. Statistical correlations were determined using univariate and partition analyses. RESULTS A median follow-up of 20 months showed recurrence in 71 (49%) patients, and the median time to recurrence was 11.9 months. Vascular invasion (P<0.01) and number of lesions (P<0.01) predicted for recurrence. Histologic grade was not correlated with recurrence. Twenty-two (31%) patients developed both surgical margin (SM) and concurrent intrahepatic recurrences, and 28 (40%) had non-SM intrahepatic recurrences with no other signs of recurrence. On partition analysis, the risk of marginal recurrence in patients with SM <1 mm and SM ≥1 mm was 35% and 13.5% respectively. Approximately 57% of patients with intrahepatic recurrence had recurrence ≤2.5 cm from SM. CONCLUSIONS Intrahepatic recurrence after partial hepatectomy is common and is significantly associated with vascular invasion and tumor stage. About 57% of patients with intrahepatic relapse had a recurrence close (≤2.5 cm) to the SM. Additionally, patients with SM <1 mm have a higher recurrence rate and may benefit from adjuvant local therapy.

Abstract
BACKGROUND Liver resection and radiofrequency ablation (RFA) are two surgical options in the treatment of patients with colorectal liver metastases (CLM). The aim of this study was to analyze patient characteristics and outcomes after resection and RFA for CLM from a single center. METHODS Between 2000 and 2010, 395 patients with CLM undergoing RFA (n = 295), liver resection (n = 94) or both (n = 6) were identified from a prospective IRB-approved database. Demographic, clinical and survival data were analyzed using univariate and multivariate analyses. RESULTS RFA patients had more comorbidities, number of liver tumors and a higher incidence of extrahepatic disease compared to the Resection patients. The 5-year overall actual survival was 17 % in the RFA, 58 % in the Resection group (p = 0.001). On multivariate analysis, multiple liver tumors, dominant lesion >3 cm, and CEA >10 ng/ml were independent predictors of overall survival. Patients were followed for a median of 20 ± 1 months. Liver and extrahepatic recurrences were seen in 69 %, and 29 % of the patients in the RFA, and 40 %, and 19 % of the patients in the Resection group, respectively. CONCLUSIONS In this large surgical series, we described the characteristics and oncologic outcomes of patients undergoing resection or RFA for CLM. By having both options available, we were able to surgically treat a large number of patients presenting with different degrees of liver tumor burden and co-morbidities, and also manage liver recurrences in follow-up.

Abstract
BACKGROUND Surgical resection is the standard treatment for liver metastases, although for the majority of patients this is not possible. Stereotactic body radiotherapy (SBRT) is an alternative local-regional therapy. The purpose of this study was to evaluate the results of SBRT for secondary liver tumours from a combined multicentre database. METHODS Variables from patients treated with SBRT from four Academic Medical Centres were entered into a common database. Local tumour control and 1-year survival rates were calculated. RESULTS In total, 153 patients (91 women) 59 ± 8.4 years old with 363 metastatic liver lesions were treated with SBRT. The underlying primary tumour arose from gastrointestinal (GI), retroperitoneal and from extra-abdominal primaries in 56%, 8% and 36% of patients, respectively. Metastases, with a gross tumour volume (GTV) of 138.5 ± 126.8 cm(3) , were treated with a total radiation dose of 37.5 ± 8.2 Gy in 5 ± 3 fractions. The 1-year overall survival was 51% with an overall local control rate of 62% at a mean follow-up of 25.2 ± 5.9 months. A complete tumour response was observed in 32% of patients. Grade 3-5 adverse events were noted in 3% of patients. CONCLUSION Secondary liver tumours treated with SBRT had a high rate of local control with a low incidence of adverse events.

Abstract
INTRODUCTION Recurrent hepatocellular carcinoma (HCC) following liver transplantation (LT) carries a poor prognosis. The aim of our study was to assess the safety and efficacy of sorafenib in patients with recurrent HCC following LT. METHODS A prospectively maintained LT database was retrospectively analyzed for patients with recurrent HCC following LT between 2001 and 2011-34 patients. Patients were divided into two groups based on whether they were prescribed sorafenib (n = 17) or not prescribed sorafenib (n = 17). The primary endpoint was overall survival. RESULTS There were no significant differences between the two groups analyzed. Seventeen patients were on sorafenib for recurrent HCC, with a mean daily dose of ~444 mg. Mean duration of treatment was ~10 months. Side effects included: thrombocytopenia, diarrhea, rising transaminases, fatigue, hand-foot skin reaction, and nausea. Survival in the sorafenib vs. non-sorafenib group was greater at three-, six-, nine-, and 12-month intervals and overall survival. CONCLUSION Sorafenib can be well tolerated and safe in patients with recurrent HCC following LT and may be associated with a modest survival benefit. To our knowledge, this is the largest single-center retrospective analysis of patients prescribed sorafenib for recurrent HCC after LT.

Abstract
e15015 Background: Partial resection is the most common surgical management of primary hepatocellular carcinoma (HCC), yet long-term prognosis remains poor, with 3-year intrahepatic recurrence rates up to 80%. A percentage of these occur within close proximity to the original tumor site. We conducted a retrospective review of liver resections at the Cleveland Clinic to determine rates and patterns of close tumor failure to inform future treatment. Methods: 147 patients, identified from an IRB approved database, underwent partial hepatectomy for definitive treatment of HCC from 1996-2012. All were followed with CT or MRI for indications of recurrence, defined as characteristic or biopsy proven liver lesions absent from previous imaging. Patients were divided into two groups: local recurrence (≤2 cm from surgical margin, A) and non-local intrahepatic recurrence (>2 cm from surgical margin, B). Logistic regression modeling was used for statistical analysis. Results: 73 (49.7%) patients had tumor recurrence, within a median time of 11.9 months (range: 1.6-69.9 months). 5 (6.8%) had extrahepatic recurrences only and were excluded from analysis. Groups A (n=19) and B (n=49) were demographically comparable. Mean tumor size was 8.9 cm (range: 2.6-14.5 cm) and 7.5 cm (range: 1.5-20 cm) respectively. In Group A, 6 (32%) had local lesions exclusively and 13 (68%) had concurrent local and non-local intrahepatic failure. Vascular invasion correlated with overall recurrence (p = 0.01). Patients with local recurrence were more likely to have a single lesion at initial diagnosis (p = 0.02) and had a shorter median time to surgery (p = 0.02). Presence of cirrhosis, tumor size, grade, margin status and tumor rupture were not significant correlates. Conclusions: In our population, 49.7% of patients had HCC recurrence. 26% of these recurrences were local failures. Vascular invasion correlated with overall recurrence. A single lesion and shorter time from diagnosis to surgery were associated specifically with local recurrence. Our findings open the possibility of employing intra-operative and/or adjuvant radiation therapy, which have demonstrated good local control with limited toxicity in other cancers, for patients at increased risk of local failure of HCC.

Abstract
BACKGROUND Locoregional therapies (LRTs) are treatments to achieve local control of hepatocellular carcinoma (HCC). Correlation between radiologic response to LRT and degree of induced tumor necrosis is not well understood. The aim of this study was to evaluate different levels of radiologic response after pre-liver transplant (LT) LRT and its correlation with percentage of tumor necrosis on explanted histopathology. METHODS Institutional Review Board approved LT database was queried for treated HCC in patients undergoing LT. Radiologic response was evaluated to predict tumor necrosis in the explanted liver. Tumor response was evaluated 1 to 3 months after LRT with computed tomography or MRI via Response Evaluation Criteria in Solid Tumors (RECIST), and European Association for the Study of the Liver (EASL) guidelines. LRT was repeated as needed until time of LT. Histological tumor necrosis was graded as complete (100%), partial (50%-99%), or poor (<50%). RESULTS Between 2002 and 2011, 128 patients (97 men and 31 women) received pre-LT LRT including transarterial therapy (93), radiofrequency ablation (20), or combination of both (15). The mean age of the patients was 58+/-9 years. Their mean follow-up was 35+/-27 months. The median waitlist time was 55 days. One hundred (78%) patients had HCC within the Milan criteria at the initial radiologic diagnosis. Nineteen (15%) of the patients had complete tumor necrosis on histopathology analysis. Fifty (39%) of the patients exhibited partial necrosis, 52 (41%) showed poor or no necrosis and 7 (5%) showed progressive disease. The overall pre-LT radiologic staging was correlated with explant pathology in 73 (57%) of the patients. Underestimated tumor stage was noted in 49 (38%) patients, and overestimated tumor stage in 6 (5%) patients. The post-LT 3-year overall survival and disease free survival were 82% and 80%, and the rates for complete and partial tumor necrosis were 100% vs 78% (P=0.02) and 100% vs 75% (P=0.03), respectively. CONCLUSIONS In the current era, interpretation of radiologic response after LRT for HCC does not correlate accurately with histologic tumor necrosis. Total tumor necrosis is the goal of LRT; therefore, evolution in its performance is needed. Similarly, ways to predict therapy induced tumor necrosis via radiological investigation need to be improved.

Abstract
BACKGROUND Ventral hernia repair (VHR) with mesh performed concurrently with colorectal surgery is presumably associated with significant risks of infection and recurrence. The purpose of this study is to evaluate the outcomes of patients undergoing VHR with non-absorbable mesh (NAM) or biological mesh (BM) at the same time as open colorectal surgery. METHODS A retrospective review of short- and long-term outcomes for 25 patients undergoing repair of VHR with NAM or BM at the same time as an open colorectal procedure from 1991 to 2007 was performed. RESULTS The mean age of the patients was 50.8 ± 12.7 years. Fifteen patients (60 %) underwent VHR with NAM versus 10 (40 %) with BM at the time of colorectal surgery. Mean follow-up after surgery was 32.9 ± 38.2 months. Overall wound infection, mesh infection and hernia recurrence rates were 44, 36 and 36 %, respectively. There was no difference between the NAM and BM mesh repair groups in terms of operative indications (p = 0.23) and operations performed (p = 0.47). Both groups had similar gender, ASA score, age, BMI, operating time, hernia recurrence rate, wound infection and follow-up. CONCLUSIONS Although a proportion of patients who undergo concomitant use of mesh for VHR during colorectal resection has reasonable outcomes, there is a high associated risk of wound and mesh infection. Thus, a judicious decision regarding the use of mesh for hernia repair needs to be made on a case-by-case basis for patients undergoing open bowel surgery at the same time.

Abstract
AIM The role of biological therapy in perianal fistulas associated with Crohn's disease (CD) is uncertain as available data are confused and conflicting. In order to provide some clarity to the issue we have examined a large cohort of patients with perianal fistulas and CD and stratified them according to use of biological agents. METHOD Patients with perianal Crohn's fistulas treated between June 1999 and June 2009 were stratified according to use of biological agents and outcome was examined. Healing was defined as absence of fistula or drainage. Prior to surgery perianal sepsis was eradicated with drains or setons. Endpoints were defined as either complete healing, improvement (minimal symptoms and drainage) or unhealed, as noted at subsequent outpatient follow-up. Variables assessed were age, body mass index, smoking, perineal involvement with Crohn's granuloma and type of procedure. Fisher's exact test and χ(2) test were used for analysis. RESULTS Two hundred and eighteen patients had anal fistulas and CD. Mean follow-up was 3.2±3 years with mean age 38.8±12.2years and body mass index of 25.3±6. One hundred and seventeen patients (53.7%) underwent surgery alone (Group A) and 101 patients (46.3%) underwent surgery and biological immunomodulator treatments (Group B). Demographic data and CD history were similar between groups. Surgeries included seton drainge (n=90), fistulotomy (n=22), rectal advancement flap (n=39), fistulotomy plus seton (n=47) and others (n=20). Overall improvement in Group A was in 42 patients (35.9%) vs 72 patients (71.3%) in Group B (P=0.001). There was no significant difference in other studied variables between both groups. CONCLUSIONS There is a definite role for biological therapy as an adjuvant to surgery in patients with perianal fistulas and CD.

Abstract
OBJECTIVES Liver transplantation (LT) in Milan Criteria (MC) hepatocellular carcinoma (HCC) has excellent outcomes. Pre-transplant loco-regional therapy (LRT) has been used to downstage HCC to meet the MC. However, its benefit in patients with a brief waiting time to transplant remains unclear. This study evaluated outcomes in patients with short waitlist times to LT for MC-compliant HCC. METHODS Patients undergoing LT for MC HCC at either of two transplant centres between 2002 and 2009 were retrospectively evaluated for outcome. Patients for whom post-transplant follow-up amounted to <12 months were excluded. RESULTS A total of 225 patients were included, 93 (41.3%) of whom received neoadjuvant LRT. The median waiting time to transplant was 48 days. Mean post-transplant follow-up was 32.2 months. Overall and disease-free survival at 1 year, 3 years and 5 years were 93.1%, 82.4% and 72.6%, and 91.3%, 79.3% and 70.6%, respectively. There was no difference in overall (P= 0.94) and disease-free survival (P= 0.94) between groups who received and did not receive pre-LT LRT. There were also no disparities in survival or tumour recurrence among categories of patients (with single tumours measuring <3 cm, with single tumours measuring 3-5 cm, with multiple tumours). CONCLUSIONS Loco-regional therapy followed by rapid transplantation in MC HCC appears not to have an impact on post-transplant outcome.

Abstract
BACKGROUND An excess of 100 000 individuals are diagnosed with primary liver tumors every year in USA but less than 20% of those patients are amenable to definitive surgical management due to advanced local disease or comorbidities. Local therapies to arrest tumor growth have limited response and have shown no improvement on patient survival. Stereotactic body radiotherapy (SBRT) has emerged as an alternative local ablative therapy. The purpose of this study was to evaluate the tumor response to SBRT in a combined multicenter database. STUDY DESIGN Patients with advanced hepatocellular carcinoma (HCC, n = 21) or intrahepatic cholangiocarcinoma (ICC, n = 11) treated with SBRT from four Academic Medical Centers were entered into a common database. Statistical analyses were performed for freedom from local progression (FFLP) and patient survival. RESULTS The overall FFLP for advanced HCC was 63% at a median follow-up of 12.9 months. Median tumor volume decreased from 334.2 to 135 cm(3) (p < 0.004). The median time to local progression was 6.3 months. The 1- and 2-years overall survival rates were 87% and 55%, respectively. Patients with ICC had an overall FFLP of 55.5% at a median follow-up of 7.8 months. The median time to local progression was 4.2 months and the six-month and one-year overall survival rates were 75% and 45%, respectively. The incidence of grade 1-2 toxicities, mostly nausea and fatigue, was 39.5%. Grade 3 and 4 toxicities were present in two and one patients, respectively. CONCLUSION Higher rates of FFLP were achieved by SBRT in the treatment of primary liver malignancies with low toxicity.

Abstract
BACKGROUND The strongest predictor of tumor relapse after liver transplantation for hepatocellular carcinoma (HCC) is vascular invasion, appreciated only on explant analysis. High serum level of vascular endothelial growth factor (VEGF) is associated with worse outcomes after resection or locoregional therapies but its role in liver transplantation remains undefined. OBJECTIVE We report the first western prospective study exploring serum VEGF in HCC liver transplant patients, correlating pre-operative serum VEGF with poor prognostic histologic features during explant analysis. METHODS Between May 2008, and June 2010, 75 HCC patients underwent liver transplantation at our institution. Serum VEGF was measured every 3 months until liver transplantation and correlated with histopathologic findings on explant. RESULTS There was no significant correlation between pre-transplant serum VEGF levels and tumor burden (median 31.0 pg/mL vs. 42.5 pg/mL, p=0.33, for tumors within and beyond the Milan criteria, respectively). Pre-transplant VEGF levels were higher in poorly differentiated tumors compared to well to moderately differentiated tumors, but not statistically significant (median 49.0 pg/mL vs. 31.0 pg/mL, p=0.26). Pre-transplant VEGF did not correlate with vascular invasion (median 37.0 pg/mL vs. 31.0 pg/mL, p=0.35, in the presence and absence of vascular invasion, respectively). CONCLUSION Pre-operative serum VEGF fails to predict unfavorable histologic HCC features in patients undergoing liver transplantation. Role of serum VEGF in liver transplant HCC patients remains unclear.

Abstract
AIM We reviewed the functional results and quality of life (QOL) of patients who had had an ileoanal pouch (IPAA) for at least 15 years. METHOD Retrospective analysis was undertaken of data accrued prospectively into a pouch database since 1983. Patients who had retained an IPAA for at least 15 years were identified. Trends in IPAA function and QOL of the patients were determined over a time-period of 15 years after formation of the IPAA. Data were compared for patients who were < 35, 35-55 and > 55 years of age when the IPAA was formed. RESULTS Three hundred and ninety-six of a total of 3276 patients in the database (53% men, median age 36 years and median follow-up 17.1 years) underwent IPAA with at least 15 years of follow-up. The final pathology was ulcerative colitis in 78%; 66.4% of patients had a restorative proctocolectomy, 91.4% underwent temporary diversion, 59% had a J-pouch configuration and 63.1% a stapled anastomosis. The frequency of bowel movements remained the same over the follow-up period. There was an increase in the incidence of incontinence and urgency after 15 years with no significant change in dietary, social, work and sexual restrictions during follow-up. Patients in all three age groups experienced deterioration in pouch function at 15 years of follow up compared with the function at 5 years. The QOL of the patients remained high and stable. CONCLUSION There is a deterioration of pouch function after 15 years, irrespective of the age of the patient when the IPAA was formed. Despite this, QOL appears to be high for all patients who retain their pouch.

Abstract
BACKGROUND AND AIM The majority of patients who undergo orthotopic liver transplantation (OLT) for hepatocellular carcinoma (HCC) have a very good prognosis if the tumor is within the Milan criteria. However, 10-15% of patients will have reoccurrence after OLT. Currently, sorafenib is available for advanced HCC. The safety and efficacy of sorafenib in this population has not been reported. METHODS We retrospectively looked at 54 patients who received sorafenib for advanced HCC. Out of 54 patients, we analyzed 9 who received sorafenib after OLT for HCC reoccurrence at Cleveland Clinic. RESULT The median age at the time treatment with sorafenib was initiated was 59 years (range 46-77). Two patients received prior local therapy. Most of the toxicity was expected side effects from sorafenib except in 1 patient who developed hematological toxicity. Six patients required dose reduction secondary to toxicity. There were no unexpected complications from interaction with immunosuppressive medication. One patient achieved complete radiographic remission. Median survival from the start of sorafenib had not been reached at the time of writing; however, the 4-month survival rate is currently estimated to be 84 ± 15%, and 1 patient with lung reoccurrence has been treated for almost 18 months thus far. CONCLUSION Sorafenib can be used in patients with recurrent HCC after liver transplantation with tolerable toxicity; however, dose adjustment may be required. A larger prospective study is necessary to determine the efficacy of sorafenib in this group of patients.

Abstract
PURPOSE Rectovaginal fistula (RVF) repair can be challenging. Additionally, women may experience sexual dysfunction and psychosocial ramifications even after a successful repair. The aim of this study was to investigate variables looking for predictors of healing/failure and examine long-term quality-of-life (QOL) and sexual function in women with low RVF from obstetrical or cryptoglandular etiology METHODS From June 1997-2009, 268 women underwent RVF repair. Of those, 100 with obstetric or cryptoglandular etiology agreed to participate in this study. Healing, type of procedure, use of seton or stoma, number of previous procedures, smoking, age, body mass index (BMI), dyspareunia, QOL using SF-12, FIQL, IBS-QOL, and female sexual function index was obtained from our prospective database and telephone contact. Fisher's exact test, chi-square test, and multivariable-logistic-regression model were used to identify the variables associated with healing/failure. RESULTS Mean follow-up was 45.8 ± 39.2 months; mean age 42.8 ± 10.5 years; and BMI was 28.8 ± 7.6. Sixty (60%) fistulas were obstetric and 40 (40%) cryptoglandular and 68/100 patients (68%) healed. On multivariate analysis, treatment failure was related to a heavier BMI (p = 0.001) and number of repairs (p = 0.02). Looking at each type of repair, episioproctotomy had significant healing compared to the other choices (but was not significant on multivariate analysis). Forty-seven women were sexually active at follow-up and 12/47 (25.5%) reported dyspareunia. Fecal incontinence was reported preoperatively in 42 women, more often in those with obstetric-related RVF (76% vs. 24% p < 0.05). Healing was not affected by age, smoking, co-morbidities, preoperative seton, or stoma use. Fecal and sexual function and QOL were comparable between women with healed and unhealed RVF. CONCLUSION Patients with higher BMI and more repairs had a decreased healing rate following RVF repair. Despite surgical outcome, QOL and sexual function were surprisingly similar regardless of fistula healing.

Abstract
OBJECTIVE The aim of this study was to analyse the efficacy of the anal fistulae plug (Cook Surgisis AFP) for the management of complex anal fistulae. METHOD A review of patients with anal fistulae treated using Cook Surgisis AFP between October 2005 and 2007 was undertaken. Patient's demographics, fistulae aetiology and success rates were recorded. RESULTS Thirty-three patients underwent 49 plug insertions. The median age was 44.4 years; 18 females. The fistulae aetiology was cryptoglandular in 61% and Crohn's disease in 39%. The median follow up 221.5 days (range 44-684). Twenty-one patients had previous failed surgery. Twenty-eight patients had draining setons in situ at time of plug placement. The overall success rate was 8/32 patients (25%). Two of the 22 Crohn's fistulae healed (9.1%) and 9/26(34.6%) cryptoglandular fistulae healed. The reasons for failure were sepsis in 87% and plug dislodgement in 13%. Significant predictor factors for improved outcome were African-Americans patients (P = 0.009), and presence of seton (P = 0.05). CONCLUSIONS Anal fistulae plug was associated with a lower success rate than previously reported. Septic complications were the main reason for failure.

Abstract
This review describes our program and its outcomes and then provides an in-depth focuses into many of the unique aspects of our practice that have been important to the success of the program. These include a global appreciation for the impact and various presentations of chronic portal hypertension. We have sought to better understand and describe the various effects it can have on local allograft hemodynamics and graft survival. Intraoperative blood flow measurements of the hepatic artery and portal vein are important. Postoperative follow-up with Doppler ultrasound has been essential for both partial and whole grafts. A better understanding of systemic and graft hemodynamics has changed our clinical practice with regards to the intra- and post-operative management of the hepatic artery and portal vein. We have also focused on the issue of hepatocellular carcinoma, one of the major indications for liver transplantation. We have sought to better understand the heterogeneous clinical presentations of this disease and how to best approach them in a multidisciplinary fashion. Finally, we describe the various methods we have utilized to increase the number of hepatic grafts available for our patients. We have aggressively utilized all forms of grafts; living and deceased; partial and whole; and extended and standard criteria donors. We have done this with the focus on living donor safety and then concentrated on finding the best graft for the individual patient in the context of the national allocation systems in which we all work.

Abstract
PURPOSE Perineal wound complications have a significant impact on postoperative morbidity after excision of the rectum and anus. The aim of this study is to evaluate factors affecting perineal wound complications after primary closure of the wound following abdominoperineal resection. METHODS Data were reviewed from all patients who underwent abdominoperineal resection for rectal carcinoma between 1982 and 2007. Data pertaining to demographics, tumor characteristics, and use of preoperative neoadjuvant therapy were retrieved. Complications studied included delayed wound healing, wound infection, dehiscence, abscess or sinus, reoperation, and perineal hernias. Patients who developed perineal wound complications (Group A) were compared with the remaining patients (Group B) to evaluate factors associated with the development of perineal wound complications. RESULTS Six hundred ninety-six patients (59% male) met the inclusion criteria. The mean age was 63 years (standard deviation, 13), and the mean body mass index was 28.9 kg/m2 (standard deviation, 7.8). Two hundred seventy-three patients (39.2%) received neoadjuvant chemoradiation. The overall rate of wound complications was 16.2%, and reoperation was required in 5.2% of patients. Group A and Group B patients were similar with respect to age (P = 0.1), gender (P = 0.7), grade (P = 0.4), and stage of disease (P = 0.5). A greater proportion of Group A patients had associated comorbidity (P = 0.001), obesity (0.04), neoadjuvant chemoradiation (0.02), and intraoperative bleeding (0.04). In multivariate analysis, comorbidity was the only independent factor associated with the development of perineal complications (odds ratio, 1.8 (1.09-2.96)). CONCLUSIONS Most patients have perineal wound healing without complications after abdominoperineal resection. In multivariate analysis, comorbidity was the only significant factor that predicted perineal wound complications.

Abstract
BACKGROUND This study aimed to assess the number of lymph nodes (LNs) harvested after laparoscopic and open colorectal cancer resections. METHODS Between 1996 and 2007, 431 colorectal cancer patients underwent laparoscopic resection. During the periods of 1996-1997, 2002-2003, and 2006-2007, 243 patients undergoing laparoscopic colorectal cancer resection were matched 1-2 by age, operation, gender, operation date, body mass index (BMI), and tumor stage (TNM) to 486 patients undergoing open surgery. The numbers of examined and involved LNs were compared according to tumor location and year of surgery. RESULTS Colorectal cancer resections (243 laparoscopic and 486 open procedures) were performed for 729 patients (447 men) with a mean age of 66.2 +/- 12.3 years and a mean BMI of 28.5 +/- 7.3. The mean number of LNs per case was 24.8 +/- 20.6. The number of LNs retrieved did not differ between laparoscopic and open surgery (p = 0.4). A significant difference was observed between the number of involved LNs retrieved laparoscopically (2.2 +/- 3.8) and the number retrieved by open surgery (1.6 +/- 4; p = 0.03). There were significant differences between the numbers of LNs retrieved from the right colon (28.1 +/- 14.6), left colon (24.5 +/- 17.6), and rectum (19.1 +/- 15.1) (p < 0.001). There were significantly fewer examined LNs in laparoscopic than in open cases during 2002 and 2003 (p = 0.003). CONCLUSION Laparoscopic resection of colorectal cancer can achieve lymph node retrieval similar to that achieved by the open approach. In this era of new technology, laparoscopic lymph node harvest is becoming more optimized.

Abstract
Fibrolamellar hepatocellular carcinoma (FL HCC) is an uncommon variant of hepatocellular carcinoma occurring usually in non-cirrhotic livers. Hepatic resection or transplantation offers the only chance of cure. We reviewed our experience of surgery for FL HCC from 1985-1998. Twenty patients with FL HCC (13 females and 7 males) median age 27 years (range 12-69) were treated either by hepatic resection [n = 11; extended right hepatectomy (5), extended left hepatectomy (1), right hemihepatectomy (2), left hemihepatectomy (2), left lateral segmentectomy (1)] or, if the disease was non-resectable, by transplantation (n = 9). The median follow up was 25 months (1-63). The prognostic factors analysed included size [less than 5 cm (3 patients), more than 5 cm (17 patients)], number [solitary (16 patients), multiple (4 patients)], capsular invasion (6 patients), vascular invasion (11 patients) and lymph node invasion (6 patients). The overall survival at 1, 3 and 5 years was 89.5, 75 and 50%, respectively. The liver resection survival was better than liver transplantation survival at 3 years 100 vs 76%, respectively (P < 0.025). Although all prognostic factors analysed did not show a significant difference, there is tendency that tumour stage was the most significant for prognosis. Most of the patients in this study are young and presented without specific symptoms, with normal liver function range and had no tumour marker to help in diagnosis. As a result most of our patients were diagnosed late. However the outcome of surgical intervention was favourable.

Abstract
Hepatocellular carcinoma (HCC) is the sixth most common cancer of men and eleventh most common cancer of women world-wide. However, because almost every individual who develops liver cancer dies of the disease, HCC is the third most common cause of the cancer deaths in men and seventh most common in women. The treatment of choice for hepatocellular carcinoma remains surgical resection or liver transplantation, in carefully selected cases. In patients with hepatocellular carcinoma not amenable to surgical intervention a variety of different therapeutic interventions have been investigated. These include direct ablation of the tumour using agents such as ethanol or acetic acid, transcatheter arterial chemoembolization, or systemic chemotherapy. The evaluation of their efficacy is compromised by the paucity of adequately powered randomised clinical trials. The main challenge facing the research community over the next decade is to prioritise the most promising treatments and take these forward into multicentre controlled trials. Even if these fail to improve results, they will help reduce the variation in clinical practice by eliminating anecdotal treatment.

Abstract
Surgery remains the treatment of choice for hepatocellular carcinoma (HCC). For HCC without underlying cirrhosis resection remains the mainstay treatment option. Prognosis depends on the stage of the tumor. Survival appears to be better for small (less than 5 cm) solitary tumors with negative resection margins and absence of vascular invasion. At present, liver transplantation does not have an established role in the treatment of HCC in a non-cirrhotic liver. Because of the high recurrence rate, it should not be considered for more advanced disease which is not amenable to resection. The surgical approach in cirrhotics depends not only on the stage of the tumor but also on the liver functional reserve. Tumor size, presence of multifocal disease, and vascular invasion determine the risk of HCC recurrence after resection, and the functional stability of the liver determines both resectability and outcome. In societies in which transplantation is not available, small tumors will be treated with liver resection. The outcome in patients with well preserved liver function is relatively good, at least in the medium term. However, recurrent tumor and progressive hepatic decompensation have significant adverse effects on long-term survival. Poor functional reserve may be associated with significant perioperative mortality and lower survival due to progressive liver failure. In our opinion, for small cirrhosis-related HCCs, liver transplantation offers better long-term prospects than resection. Therefore, if liver transplantation is available as an option it should be considered as the treatment of choice, particularly for younger patients with otherwise good life expectancy.
