ABSTRACT

BACKGROUND: The relevance of laparoscopic resection of intrahepatic cholangiocarcinoma (ICC) remains debated. The aim of this study was to compare laparoscopic (LLR) and open (OLR) liver resection for ICC, with specific focus on textbook outcome and lymph node dissection (LND). METHODS: Patients undergoing LLR or OLR for ICC were included from two French, nationwide hepatopancreatobiliary surveys undertaken between 2000 and 2017. Patients with negative margins, and without transfusion, severe complications, prolonged hospital stay, readmission or death were considered to have a textbook outcome. Patients who achieved both a textbook outcome and LND were deemed to have an adjusted textbook outcome. OLR and LLR were compared after propensity score matching. RESULTS: In total, 548 patients with ICC (127 LLR, 421 OLR) were included. Textbook-outcome and LND completion rates were 22.1 and 48.2 per cent respectively. LLR was independently associated with a decreased rate of LND (odds ratio 0.37, 95 per cent c.i. 0.20 to 0.69). After matching, 109 patients remained in each group. LLR was associated with a decreased rate of transfusion (7.3 versus 21.1 per cent; P = 0.001) and shorter hospital stay (median 7 versus 14 days; P = 0.001), but lower rate of LND (33.9 versus 73.4 per cent; P = 0.001). Patients who underwent LLR had lower rate of adjusted TO completion than patients who had OLR (6.5 versus 17.4 per cent; P = 0.012). CONCLUSION: The laparoscopic approach did not substantially improve quality of care of patients with resectable ICC.

ABSTRACT

BACKGROUND: This study aimed to identify a subgroup of recipients at low risk of haemorrhage, bile leakage and ascites following liver transplantation (LT). METHODS: Factors associated with significant postoperative ascites (more than 10 ml/kg on postoperative day 5), bile leakage and haemorrhage after LT were identified using three separate multivariable analyses in patients who had LT in 2010-2019. A model predicting the absence of all three outcomes was created and validated internally using bootstrap procedure. RESULTS: Overall, 944 recipients underwent LT. Rates of ascites, bile leakage and haemorrhage were 34.9, 7.7 and 6.0 per cent respectively. The 90-day mortality rate was 7.0 per cent. Partial liver graft (relative risk (RR) 1.31; P = 0.021), intraoperative ascites (more than 10 ml/kg suctioned after laparotomy) (RR 2.05; P = 0.001), malnutrition (RR 1.27; P = 0.006), portal vein thrombosis (RR 1.56; P = 0.024) and intraoperative blood loss greater than 1000 ml (RR 1.39; P = 0.003) were independently associated with postoperative ascites and/or bile leak and/or haemorrhage, and were introduced in the model. The model was well calibrated and predicted the absence of all three outcomes with an area under the curve of 0.76 (P = 0.001). Of the 944 patients, 218 (23.1 per cent) fulfilled the five criteria of the model, and 9.6 per cent experienced postoperative ascites (RR 0.22; P = 0.001), 1.8 per cent haemorrhage (RR 0.21; P = 0.033), 4.1 per cent bile leak (RR 0.54; P = 0.048), 40.4 per cent severe complications (RR 0.70; P = 0.001) and 1.4 per cent 90-day mortality (RR 0.13; P = 0.004). CONCLUSION: A practical model has been provided to identify patients at low risk of ascites, bile leakage and haemorrhage after LT; these patients could potentially qualify for inclusion in non-abdominal drainage protocols.

ABSTRACT

INTRODUCTION: Among various reported techniques for inferior vena cava (IVC) reconstruction, the superiority of one technique over another has not been clearly established. This study aimed at reporting the technical aspects of caval reconstruction using peritoneal patch during extended liver resections. METHODS: All consecutive patients who underwent extended liver resection associated with anterolateral caval reconstruction using a peritoneal patch from 2016 to 2019 were included in this study. Technical insights, intra-operative details, short and long-term results were reported. RESULTS: Overall six patients underwent caval reconstruction using peritoneal patch under total vascular exclusion. Half of them required veno-venous bypass. Caval involvement ranged from 30 to 50% of the circumference and from 5 to 7 cm of the length of the IVC. Caval reconstructions was performed using a peritoneal patch harvested from the falciform ligament in four cases and from the right pre-renal peritoneum and right part of the diaphragm in one Case each. Three cases underwent associated reimplantation the remnant hepatic vein. Median intra-operative blood loss and TVE duration were 500 ml and 41 min, respectively. One case experienced a severe complication (liver failure leading to death). R0 resection was achieved in all patients. All patients had patent IVC and remnant hepatic vein at last follow-up and none was on long-term therapeutic anticoagulation. CONCLUSION: Caval reconstruction using a peritoneal patch in patients undergoing extended liver resection is feasible and cost-effective and associated with excellent long-term results.

ABSTRACT

BACKGROUND: Quantification of liver surface nodularity (LSN) on routine preoperative CT images allows detection of cirrhosis and clinically significant portal hypertension. This study aimed to assess the relevance of LSN in preoperative assessment of operative risks for patients with resectable hepatocellular carcinoma (HCC). METHODS: All patients undergoing hepatectomy for HCC between 2012 and 2017 were analysed retrospectively. LSN was assessed at the liver-fat interface on the left liver lobe on preoperative CT images. The feasibility of LSN quantification was assessed. The association between LSN and outcomes (severe complications and posthepatectomy liver failure (PHLF)) was evaluated by multivariable analysis and after propensity score matching. RESULTS: Among 210 patients, LSN measurement was successful in 187 (89·0 per cent). Among these, the median LSN score was 2·42 (i.q.r. 2·21-2·66) and 52·9 per cent had severe fibrosis, including 33·7 per cent with cirrhosis. LSN score increased with hepatic venous pressure gradient (P = 0·048), severity of steatosis (P = 0·011) and fibrosis grade (P = 0·001). LSN score was independently associated with severe complications (odds ratio (OR) 5·25; P = 0·006) and PHLF (OR 6·78; P = 0·003). After matching with respect to model for end-stage liver disease, aspartate aminotransferase-to-platelet ratio index and fibrosis-4 score, patients with a LSN score of 2·63 or higher retained an increased risk of PHLF (OR 5·81; P = 0·018). In the subgroup of patients without severe fibrosis, LSN was accurate in predicting severe complications (P = 0·005). Patients with (P = 0·039) or without (P = 0·018) severe fibrosis with increased LSN score had a higher comprehensive complication index score. Among patients with cirrhosis who had clinically significant portal hypertension, a LSN value below 2·63 ruled out the risk of PHLF. CONCLUSION: LSN measurement represents a practical tool that may allow improvement in the preoperative evaluation and management of patients with HCC.


ANTECEDENTES: La cuantificación de la nodularidad de la superficie hepática (liver surface nodularity, LSN) en las imágenes de la tomografía computarizada (TC) de rutina preoperatoria permite detectar la cirrosis y la hipertensión portal clínicamente significativa (clinically significant portal hypertension, CSPH). Este estudio tuvo como objetivo evaluar la relevancia de la LSN en la evaluación preoperatoria del riesgo quirúrgico en pacientes con carcinoma hepatocelular resecable (hepatocellular carcinoma, HCC). MÉTODOS: Todos los pacientes sometidos a hepatectomía por HCC entre 2012 y 2017 fueron analizados de forma retrospectiva. La LSN se evaluó en la interfase hígado-grasa en el lóbulo hepático izquierdo en la TC preoperatoria. Se evaluó la viabilidad de la cuantificación de la LSN. La asociación entre la LSN y los resultados (complicaciones graves e insuficiencia hepática poshepatectomía (post-hepatectomy liver failure, PHLF) se analizó en un análisis multivariable y después del método de emparejamiento por puntaje de propensión. RESULTADOS: Del total de 210 pacientes, la medición de la LSN fue exitosa en 187 (89,0%). En estos pacientes, la mediana de LSN fue de 2,42 (rango intercuartílico 2,21-2,66) y el 53,0% tenía fibrosis severa, incluyendo un 33,7% con cirrosis. La LSN aumentó con el gradiente de presión venosa hepática (P = 0,048), la gravedad de la esteatosis (P = 0,011) y el grado de fibrosis (P = 0,001). La LSN se asoció de forma independiente con complicaciones graves (razón de oportunidades, odds ratio, OR = 5,25; P = 0,006) y PHLF (OR = 6,78; P = 0,003). Después de emparejar para el modelo de enfermedad hepática terminal, el índice de relación aspartato amino transferase-plaquetas y el grado de fibrosis-4, los pacientes con LSN ≥ 2,63 mantuvieron un mayor riesgo de PHLF (OR = 5,81; P = 0,018). Dentro del subgrupo de pacientes sin fibrosis severa, la LSN fue precisa en predecir complicaciones graves (P = 0,005). Los pacientes con (P = 0,039) y sin (P = 0,018) fibrosis severa con aumento de la LSN tuvieron un índice de complicación global más alto. De los pacientes cirróticos con CSPH, un valor de LSN de 2,63 descartó el riesgo de PHLF. CONCLUSIÓN: La LSN representa una herramienta práctica, que puede permitir mejorar la evaluación preoperatoria y el manejo de pacientes con HCC.

ABSTRACT

BACKGROUND: The aim was to analyse the impact of cirrhosis on short-term outcomes after laparoscopic liver resection (LLR) in a multicentre national cohort study. METHODS: This retrospective study included all patients undergoing LLR in 27 centres between 2000 and 2017. Cirrhosis was defined as F4 fibrosis on pathological examination. Short-term outcomes of patients with and without liver cirrhosis were compared after propensity score matching by centre volume, demographic and tumour characteristics, and extent of resection. RESULTS: Among 3150 patients included, LLR was performed in 774 patients with (24·6 per cent) and 2376 (75·4 per cent) without cirrhosis. Severe complication and mortality rates in patients with cirrhosis were 10·6 and 2·6 per cent respectively. Posthepatectomy liver failure (PHLF) developed in 3·6 per cent of patients with cirrhosis and was the major cause of death (11 of 20 patients). After matching, patients with cirrhosis tended to have higher rates of severe complications (odds ratio (OR) 1·74, 95 per cent c.i. 0·92 to 3·41; P = 0·096) and PHLF (OR 7·13, 0·91 to 323·10; P = 0·068) than those without cirrhosis. They also had a higher risk of death (OR 5·13, 1·08 to 48·61; P = 0·039). Rates of cardiorespiratory complications (P = 0·338), bile leakage (P = 0·286) and reoperation (P = 0·352) were similar in the two groups. Patients with cirrhosis had a longer hospital stay than those without (11 versus 8 days; P = 0·018). Centre expertise was an independent protective factor against PHLF in patients with cirrhosis (OR 0·33, 0·14 to 0·76; P = 0·010). CONCLUSION: Underlying cirrhosis remains an independent risk factor for impaired outcomes in patients undergoing LLR, even in expert centres.


ANTECEDENTES: El objetivo de este estudio fue analizar el impacto de la cirrosis en los resultados a corto plazo después de la resección hepática laparoscópica (laparoscopic liver resection, LLR) en un estudio de cohortes multicéntrico nacional. MÉTODOS: Este estudio retrospectivo incluyó todos los pacientes sometidos a LLR en 27 centros entre 2000 y 2017. La cirrosis se definió como fibrosis F4 en el examen histopatológico. Los resultados a corto plazo de los pacientes con hígado cirrótico (cirrhotic liver CL) (pacientes CL) y los pacientes con hígado no cirrótico (non-cirrhotic liver, NCL) (pacientes NCL) se compararon después de realizar un emparejamiento por puntaje de propension del volumen del centro, las características demográficas y del tumor, y la extensión de la resección. RESULTADOS: Del total de 3.150 pacientes incluidos, se realizó LLR en 774 (24,6%) pacientes CL y en 2.376 (75,4%) pacientes NCL. Las tasas de complicaciones graves y mortalidad en el grupo de pacientes CL fueron del 10,6% y 2,6%, respectivamente. La insuficiencia hepática posterior a la hepatectomía (post-hepatectomy liver failure, PHLF) fue la principal causa de mortalidad (55% de los casos) y se produjo en el 3,6% de los casos en pacientes CL. Después del emparejamiento, los pacientes CL tendieron a tener tasas más altas de complicaciones graves (razón de oportunidades, odds ratio, OR 1,74; i.c. del 95% 0,92-0,41; P = 0,096) y de PHLF (OR 7,13; i.c. del 95% 0,91-323,10; P = 0,068) en comparación con los pacientes NCL. Los pacientes CL estuvieron expuestos a un mayor riesgo de mortalidad (OR 5,13; i.c. del 95% 1,08-48,6; P = 0,039) en comparación con los pacientes NCL. Los pacientes CL presentaron tasas similares de complicaciones cardiorrespiratorias graves (P = 0,338), de fuga biliar (P = 0,286) y de reintervenciones (P = 0,352) que los pacientes NCL. Los pacientes CL tuvieron una estancia hospitalaria más larga (11 versus 8 días; P = 0,018) que los pacientes NCL. La experiencia del centro fue un factor protector independiente de PHLF (OR 0,33; i.c. del 95% 0,14-0,76; P = 0,010) pacientes CL. CONCLUSIÓN: La presencia de cirrosis subyacente sigue siendo un factor de riesgo independiente de peores resultados en pacientes sometidos a resección hepática laparoscópica, incluso en centros con experiencia.

ABSTRACT

In Europe, the prevalence of metabolic syndrome (MS) has reached the endemic rate of 25%. Non-alcoholic fatty liver disease (NAFLD) is the hepatic manifestation of MS. Its definition is histological, bringing together the different lesions associated with hepatic steatosis (fat deposits on more than 5% of hepatocytes) without alcohol consumption and following exclusion of other causes. MS and NAFLD are implicated in the carcinogenesis of hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC). At present, HCC and ICC involving MS represent 15-20% and 20-30% respectively of indications for hepatic resection in HCC and ICC. Moreover, in the industrialized nations NAFLD is tending to become the most frequent indication for liver transplantation. MS patients combine the operative risk associated with their general condition and comorbidities and the risk associated with the presence and/or severity of NAFLD. Following hepatic resection in cases of HCC and ICC complicating MS, the morbidity rate ranges from 20 to 30%, and due to cardiovascular and infectious complications, post-transplantation mortality is heightened. The operative risk incurred by MS patients necessitates appropriate management including: (i) precise characterization of the subjacent liver; (ii) an accurately targeted approach privileging detection and optimization of treatment taking into account the relevant cardiovascular risk factors; (iii) a surgical strategy adapted to the histology of the underlying liver, with optimization of the volume of the remaining (postoperative) liver.

ABSTRACT

INTRODUCTION: The French Society of Gastro-Intestinal Surgery (SociétéFrançaisedeChirurgieDigestive) and the Association of hepato-bilio-pancreatic and transplantation surgery (AssociationdeChirurgieHépato-Bilio-PancréatiqueetTransplantation) requested that clinical practice recommendations be established with regard to operating room hygiene. METHODS: The literature was analyzed according to the High Authority of Health (HauteAutoritédesanté [HAS]) methodology and after consultation of the Cochrane and Medline databases. Pertinent references were selected, and supplementary references were hand-picked from the reference lists. Only English or French language papers were retained. The recommendations of learned societies and the World Health Organization were also considered. RESULTS: Recommendations were proposed with regard to pre-operative patient preparation, skin preparation, draping, wound edge protectors, surgeon hygiene, wound closure, and operating room environment. CONCLUSION: These clinical practice recommendations should guide and improve the daily practice of gastro-intestinal surgeons.

ABSTRACT

AIM: To describe the management of blunt liver injury and to study the potential relation between delayed complications, type of trauma mechanisms and liver lesions. PATIENTS AND METHODS: This is a retrospective single center study including 116 consecutive patients admitted with blunt liver injury between 2007 and 2015. RESULTS: Initial CT-scan identified an active bleeding in 33 (28%) patients. AAST (American Association for the Surgery of Trauma) grade was 1 to 3 in 82 (71%) patients and equal to 5 in 15 (13%) patients. Eighty (69%) patients had NOM, with a success rate of 96%. Other abdominal organ lesions were associated to invasive initial management. A follow-up CT-scan was useful to detect hepatic and extra-hepatic complications (46 complications in 80 patients), even without clinical or biological abnormalities. Subsequent hepatic complications such as bleeding, pseudo aneurysms, biloma and biliary peritonitis developed in 15 patients and were associated with the severity of blunt liver injury according to AAST classification (3.7±1.0 vs. 3.0±1.1, P=0.010). Total biliary complications occurred in 13 patients and were significantly more frequently observed in patients with injury of central segments 1, 4 and 9 (69% vs. 36%, P=0.033). CONCLUSIONS: Non-operative management is possible in most blunt liver injury with a success rate of 96%. A systematic CT-scan should be advocated during follow-up, especially when AAST grade is equal or superior to 3. Biliary complications should be suspected when lesions involve segments 1, 4 and 9.

ABSTRACT

BACKGROUND: In developing countries, most inguinal hernia repairs are performed using Bassini or Shouldice techniques resulting in higher recurrence rates than with mesh placement. Our study aimed to evaluate the postoperative course and quality of life of patients undergoing inguinal hernia repair with a polyester mosquito net meshes during non-governmental organization health campaigns in Cameroon. METHODS: Patients were prospectively included from January to November 2013. Meshes were made from a polyester non-impregnated mosquito net purchased at a local market in Yaounde and sterilized on site. RESULTS: The total cost of a mesh was 0.21 USD. Among the 41 patients included in the study, 33 (80.5%) were men, 30 (72%) were farmers and the median age was 52 (21-80) years. The time between the onset of symptoms and surgery was 24 (3-240) months. Eleven (26.8%) patients had a previous history of hernia repair: 4 (9.7%) had been operated on the contralateral side and 7 (17.1%) had a recurrence. No intraoperative event related to the meshes was recorded. Three patients (7.2%) had a postoperative uninfected scrotal seroma, and 1 patient (2.4%) experienced a superficial skin infection that was treated using local care and oral antibiotics. No allergic rejection or deep infection was observed. CONCLUSIONS: Meshes made from sterilized mosquito nets are safe and effective and provide a cost-effective alternative to commercially available meshes in countries with limited resources especially during non-governmental organization health campaigns.

ABSTRACT

BACKGROUND: Although recent reports have suggested potential benefits of the laparoscopic approach in patients requiring major hepatectomy, it remains unclear whether conversion to open surgery could offset these advantages. This study aimed to determine the risk factors for and postoperative consequences of conversion in patients undergoing laparoscopic major hepatectomy (LMH). METHODS: Data for all patients undergoing LMH between 2000 and 2013 at two tertiary referral centres were reviewed retrospectively. Risk factors for conversion were determined using multivariable analysis. After propensity score matching, the outcomes of patients who underwent conversion were compared with those of matched patients undergoing laparoscopic hepatectomy who did not have conversion, operated on at the same centres, and also with matched patients operated on at another tertiary centre during the same period by an open laparotomy approach. RESULTS: Conversion was needed in 30 (13·5 per cent) of the 223 patients undergoing LMH. The most frequent reasons for conversion were bleeding and failure to progress, in 14 (47 per cent) and nine (30 per cent) patients respectively. On multivariable analysis, risk factors for conversion were patient age above 75 years (hazard ratio (HR) 7·72, 95 per cent c.i. 1·67 to 35·70; P = 0·009), diabetes (HR 4·51, 1·16 to 17·57; P = 0·030), body mass index (BMI) above 28 kg/m(2) (HR 6·41, 1·56 to 26·37; P = 0·010), tumour diameter greater than 10 cm (HR 8·91, 1·57 to 50·79; P = 0·014) and biliary reconstruction (HR 13·99, 1·82 to 238·13; P = 0·048). After propensity score matching, the complication rate in patients who had conversion was higher than in patients who did not (75 versus 47·3 per cent respectively; P = 0·038), but was not significantly different from the rate in patients treated by planned laparotomy (79 versus 67·9 per cent respectively; P = 0·438). CONCLUSION: Conversion during LMH should be anticipated in patients with raised BMI, large lesions and biliary reconstruction. Conversion does not lead to increased morbidity compared with planned laparotomy.

ABSTRACT

GOAL: The aim of this study was to objectively analyze the characteristics of abstracts submitted to the annual joint congress of the SFCD (French Society of Digestive Surgery) and the ACBHT (Association of Hepato-biliary Surgery and Transplantation), in order to identify factors associated with acceptance for presentation at the Congress and of subsequent publication in a scientific journal. MATERIAL AND METHODS: All abstracts submitted between 2005 and 2012 were retrospectively reviewed. Univariate and multivariate analysis were perfomed to determine the factors associated with acceptance for presentation at the Congress and/or for subsequent publication in the medical literature (based on PubMed). RESULTS: The number of submissions increased from 128 in 2005 to 223 in 2012, i.e., an increase of 74.2%. Among the 1352 abstracts, 1106 (81.8%) were retrospective studies while only 15 (1.1%) were randomized controlled trials. The two principal themes were hepato-bilio-pancreatic surgery in 606 studies (44.8%) and colorectal surgery in 364 studies (26.9%). The overall rate of acceptance for the Congress was 49.9%, of which 21.0% were accepted for oral presentation. In multivariate analysis, the factors associated with acceptance for oral presentation were the geographic origin of the study (P<0.001), studies including >100 patients (P=0.01), and the prospective nature of the study (P=0.045). The rate of subsequent publication was 61.9% for studies accepted for oral presentation, 39.7% for studies accepted for poster presentation, and 25.9% for studies that were not accepted (P<0.001). In multivariate analysis, the factors associated with subsequent publication were geographic origin of the study (P=0.003), the experimental character of the study (P<0.001), and acceptance for presentation at the Congress (P<0.001). CONCLUSION: Only half of the studies submitted for presentation at the annual Congress of the SFCD/ACBHT are accepted; this nevertheless constitutes a quality measure associated with nearly a 50% chance of subsequent publication in the medical literature.

ABSTRACT

OBJECTIVES: To evaluate the influence of a biliary obstruction (BO) requiring biliary bypass on both short and long-term outcomes of patients undergoing Frey's procedure for chronic pancreatitis (CP). METHODS: From 1999 to 2010, 33 consecutive patients underwent Frey's procedure for CP in two centers. Seventeen (54%) patients underwent biliary bypass to treat an associated BO. Characteristics and outcomes of these patients were compared to those of 16 others without BO. RESULTS: Patients with BO had more severe disease including lower BMI and larger pancreatic head (4 cm vs. 6 cm, p = 0.021). The operative mortality was nil. Patients with BO experienced more overall postoperative complications (71% vs. 31%, p = 0.024) but similar major complication rates (18% vs. 6%, p = 0.316) compared to those without BO. After a median follow-up of 51 (1-96) months, 91% of the patients experienced either partial or complete relief of their symptoms and 36% exhibited deterioration of their endocrine function. Multivariate analysis revealed preoperative BO to be associated with long-term impairment of endocrine function (OR: 43.249; 95% CI 2.221-84.277; p = 0.013). CONCLUSION: In patients undergoing Frey's procedure for CP, associated BO can be safely managed using biliary bypass. However, the severity of CP in these patients is responsible for a higher risk of long-term endocrine insufficiency.

ABSTRACT

BACKGROUND: The incidence of metabolic syndrome-associated hepatocellular carcinoma (MS-HCC) is increasing. However, the results following liver resection in this context have not been described in detail. METHODS: Data for all patients with metabolic syndrome as a unique risk factor for HCC who underwent liver resection between 2000 and 2011 were retrieved retrospectively from an institutional database. Pathological analysis of the underlying parenchyma included fibrosis and non-alcoholic fatty liver disease activity score. Patients were classified as having normal or abnormal underlying parenchyma. Their characteristics and outcomes were compared. RESULTS: A total of 560 resections for HCC were performed in the study interval. Sixty-two patients with metabolic syndrome, of median age 70 (range 50-84) years, underwent curative hepatectomy for HCC, including 32 major resections (52 per cent). Normal underlying parenchyma was present in 24 patients (39 per cent). The proportion of resected HCCs labelled as MS-HCC accounted for more than 15 per cent of the entire HCC population in more recent years. Mortality and major morbidity rates were 11 and 58 per cent respectively. Compared with patients with normal underlying liver, patients with abnormal liver had increased rates of mortality (0 versus 18 per cent; P = 0·026) and major complications (13 versus 42 per cent; P = 0·010). In multivariable analysis, a non-severely fibrotic yet abnormal underlying parenchyma was a risk factor for major complications (hazard ratio 5·66, 95 per cent confidence interval 1·21 to 26·52; P = 0·028). The 3-year overall and disease-free survival rates were 75 and 70 per cent respectively, and were not influenced by the underlying parenchyma. CONCLUSION: HCC in patients with metabolic syndrome is becoming more common. Liver resection is appropriate but carries a high risk, even in the absence of severe fibrosis. Favourable long-term outcomes justify refinements in the perioperative management of these patients.

ABSTRACT

Surgery remains the best curative treatment for resectable patients with colorectal liver metastases. In patients initially considered unresectable, both refinements in surgical technique using portal vein occlusion or two-step resections and increased efficiency of chemotherapy regimen with the adjunction of antiangiogenics now allow secondary resection. Recent evidence suggests almost identical long-term survival in case of secondary downstaged lesions advocating an aggressive approach. However, these data lie on disparate and nonconsensual criteria for unresectability, which often do not gather technical and oncologic components together. Furthermore, both impaired general status and damaged underlying parenchyma as a consequence of prolonged chemotherapy to achieve resectability as well as the technical challenge required to perform adequate carcinologic resection could increase the operative risk in such patients. In our experience, a subgroup of slow chemo-responding initially unresectable patients who required preoperative liver volume modulation after ≥ 12 cycles of chemotherapy to achieve sufficient response experienced dramatically high operative risk which jeopardized postoperative chemotherapy and subsequently put these patients at increased risk of recurrence. Whether all patients preoperatively amenable to surgery using intensive chemotherapy and complex surgical strategy actually benefit from such an aggressive approach is a matter of ongoing debate, which needs a reappraisal.

ABSTRACT

PURPOSE: The purpose of this study is to review indications and results of surgical treatments of hepatocellular carcinoma (HCC). This tumor, which represents one of the most common malignancies worldwide, is characterized by its prominent development in patients with chronic liver disease (CLD). Liver transplantation (LT) is considered as the ideal treatment of limited HCC removing both tumor(s) and the pre-neoplasic underlying diseased liver. However, this treatment, which is not available in many countries, is restricted to patients with minimum risk of tumor recurrence under immunosuppression. The risk of recurrence is minimized in patients fulfilling the Milan criteria with a tendency to accept slight expansion of size in patients with favourable natural history and low AFP level. Increasing duration in the waiting list before LT leads several teams to use neoadjuvant therapies such as percutaneous ablation, TACE and liver resection. Liver resection in cirrhotic patients with good liver function remains the most available efficient treatment of patients with HCC. Better liver function assessment, understanding of the segmental liver anatomy with more accurate imaging studies and surgical technique refinements are the most important factors that have contributed to reduce mortality with an expecting 5 years survival of 70%. There is considerable interest in combined treatment associating resection and LT. Transplantable patients with good liver function should be considered for liver resection as primary therapy and for LT in case of tumor recurrence. This salvage strategy is refined using pathological analysis of the resected specimen which identifies histological pejorative factors allowing selecting patients who should transplanted before recurrence. CONCLUSIONS: The improvement of survival in HCC patients after surgical treatment results from refinements in surgical technique and better identification of adverse prognostic factors.
