RESUMO

The presence of a pre-existing or recent extra-hepatic solid tumor was considered for a long time as an absolute contraindication to liver transplantation, by fear of futility with an unacceptable increase in non-liver-related mortality. However, cancer-related mortality in solid malignancies is heterogeneous, and experts suggest that case-by-case multidisciplinary decisions should be made. Here, we report the cases of 3 patients with favorable oncological and liver outcome in patients with renal cell carcinoma detected during pre-transplant evaluation that nonetheless underwent liver transplantation.

RESUMO

GOAL OF THE STUDY: Concomitant liver metastases are discovered at the time of diagnosis in 25% of patients with colorectal cancers. The appropriate time to restore digestive continuity after stoma creation during rectal surgery has not yet been established. The objective of this study is to assess the morbidity of stoma reversal during the secondary hepatectomy procedure. PATIENTS AND METHODS: This was a single-center retrospective case-control study including patients who underwent ileostomy or colostomy reversal by a direct approach (REVERSAL group) compared to those who did not undergo stoma reversal (NON-REVERSAL group) during hepatic resection of rectal cancer metastasis between 2004 and 2016. Peri-operative data were collected. The primary outcome measure was the comprehensive complication index (CCI). The secondary outcomes were overall mortality, liver-related morbidity, duration of hospital stay and occurrence of gastrointestinal leaks. Statistical analysis was carried out using SPSS 23.0 software. RESULTS: Thirty liver resections were included; 14 in the REVERSAL group (female/male=11/19, age=60 years). No statistically significant difference was observed in the CCI scores (15 vs. 20.8; P=0.6). Complications occurred in 9 (64%) and 8 (50%) patients in the REVERSAL and NON-REVERSAL groups, respectively (P=0.48). No gastro-intestinal leaks or post-operative mortality occurred. CONCLUSION: Stoma reversal during hepatectomy for liver metastasis from a primary rectal cancer represents a safe alternative since post-operative outcome was not associated with additional morbidity in this series.

RESUMO

The hepatic compartment syndrome (HCS) corresponds to compression of the intraparenchymal liver tissue (intrahepatic pressure greater than the portal vein pressure, i.e. >10-15mmHg) caused by a subcapsular or intraparenchymal hematoma of the liver. It can lead to reversal of portal flow and hepatic parenchymal necrosis. We report the case of a patient who underwent a right radical nephrectomy by laparoscopy and who presented with HCS due to a subcapsular hematoma of the liver. Emergency decompression of the liver via laparotomy was performed, which allowed rapid clinical and laboratory improvement.

RESUMO

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.

RESUMO

Mesenteric and portal vein involvement is seen frequently in pancreatic neoplastic disease and requires venous resection to obtain clear surgical margins. If sufficient collateral circulation is present, venous resection can be performed without reconstruction and without substantial impact on venous drainage.

RESUMO

BACKGROUND: Biliary fistula is one of the most common complications after hepatectomy. This study evaluated the effect of transcystic biliary drainage during hepatectomy on the occurrence of postoperative biliary fistula. METHODS: This multicentre RCT was carried out from 2009 to 2016 in nine centres. Patients were randomized to transcystic biliary drainage or no transcystic drainage (control). Patients underwent hepatectomy (more than 2 segments) of non-cirrhotic livers. The primary endpoint was the occurrence of biliary fistula after surgery. Secondary endpoints were morbidity, postoperative mortality, duration of hospital stay, reoperation, readmission to hospital, and complications caused by catheters. Intention-to-treat and per-protocol analyses were performed. RESULTS: A total of 310 patients were randomized. In intention-to-treat analysis, there were 158 patients in the transcystic group and 149 in the control group. Seven patients were removed from the per-protocol analysis owing to protocol deviations. The biliary fistula rate was 5·9 per cent in intention-to-treat and 6·0 per cent in per-protocol analyses. The rate was similar in the transcystic and control groups (5·7 versus 6·0 per cent; P = 1·000). There were no differences in terms of morbidity (49·4 versus 46·3 per cent; P = 0·731), mortality (2·5 versus 4·7 per cent; P = 0·367) and reoperations (4·4 versus 10·1 per cent; P = 1·000). Median duration of hospital stay was longer in the transcystic group (11 versus 10 days; P = 0·042). The biliary fistula risk was associated with the width and length of the hepatic cut surface. CONCLUSION: This randomized trial did not demonstrate superiority of transcystic drainage during hepatectomy in preventing biliary fistula. The use of transcystic drainage during hepatectomy to prevent postoperative biliary fistula is not recommended. Registration number: NCT01469442 ( http://www.clinicaltrials.gov).


ANTECEDENTES: La fístula biliar es una de las complicaciones más comunes después de la hepatectomía. Este estudio evalúa el efecto del drenaje biliar transcístico durante la hepatectomía en la aparición de una fístula biliar postoperatoria. MÉTODOS: Este ensayo prospectivo aleatorizado y multicéntrico (Clinical Trial NCT01469442) con dos grupos de estudio (grupo transcístico versus grupo control) se llevó a cabo de 2009 a 2016 en 9 centros. Los pacientes fueron sometidos a una hepatectomía (≥ 2 segmentos) en hígados no cirróticos. El resultado principal fue la aparición de una fístula biliar después de la cirugía. Los resultados secundarios fueron la morbilidad, la mortalidad postoperatoria, la duración de la estancia hospitalaria, la reintervención, la necesidad de reingreso y las complicaciones causadas por los catéteres. Se realizaron análisis por intención de tratamiento y por protocolo. RESULTADOS: Un total de 310 pacientes fueron randomizados. Por intención de tratamiento, 158 pacientes fueron aleatorizados al grupo transcístico y 149 al grupo control. Siete pacientes fueron excluidos del análisis por protocolo por desviaciones del protocolo. La tasa de fístula biliar fue del 5,9% en el análisis por intención de tratamiento y del 6,0% en el análisis por protocolo. Esta tasa fue similar para el grupo transcístico y para el grupo control: 5,7% versus 6,0% (P = 1). No hubo diferencias en términos de morbilidad (49,4% versus 46,9%, P = 0,731), mortalidad (2,5% versus 4,7%, P = 0,367) y reintervenciones (4,4% versus 10,1%, P = 1). La mediana de la duración de la estancia hospitalaria fue mayor para el grupo transcístico (11 versus 10 días, P = 0,042). El riesgo de fístula biliar se correlacionó con el grosor y la longitud de la transección hepática. CONCLUSIÓN: Este ensayo aleatorizado no demuestra la superioridad del drenaje transcístico durante la hepatectomía para prevenir la fístula biliar. No se recomienda el uso de drenaje transcístico durante la hepatectomía para prevenir la fístula biliar postoperatoria.

RESUMO

BACKGROUND: The operative risk of hepatectomy under antiplatelet therapy is unknown. This study sought to assess the outcomes of elective hepatectomy performed with or without aspirin continuation in a well balanced matched cohort. METHODS: Data were retrieved from a multicentre prospective observational study. Aspirin and control groups were compared by non-standardized methods and by propensity score (PS) matching analysis. The main outcome was severe (Dindo-Clavien grade IIIa or more) haemorrhage. Other outcomes analysed were intraoperative transfusion, overall haemorrhage, major morbidity, comprehensive complication index (CCI) score, thromboembolic complications, ischaemic complications and mortality. RESULTS: Before matching, there were 118 patients in the aspirin group and 1685 in the control group. ASA fitness grade, cardiovascular disease, previous history of angina pectoris, angioplasty, diabetes, use of vitamin K antagonists, cirrhosis and type of hepatectomy were significantly different between the groups. After PS matching, 108 patients were included in each group. There were no statistically significant differences between the aspirin and control groups in severe haemorrhage (6·5 versus 5·6 per cent respectively; odds ratio (OR) 1·18, 95 per cent c.i. 0·38 to 3·62), intraoperative transfusion (23·4 versus 23·7 per cent; OR 0·98, 0·51 to 1·87), overall haemorrhage (10·2 versus 12·0 per cent; OR 0·83, 0·35 to 1·94), CCI score (24 versus 28; P = 0·520), major complications (23·1 versus 13·9 per cent; OR 1·82, 0·92 to 3·79) and 90-day mortality (5·6 versus 4·6 per cent; OR 1·21, 0·36 to 4·09). CONCLUSION: This observational study suggested that aspirin continuation is not associated with a higher rate of bleeding-related complications after elective hepatic surgery.

RESUMO

BACKGROUND: Biliary leakage remains a major cause of morbidity after liver resection. Previous prognostic studies of posthepatectomy biliary leakage (PHBL) lacked power, population homogeneity, and model validation. The present study aimed to develop a risk score for predicting severe PHBL. METHODS: In this multicentre observational study, patients who underwent liver resection without hepaticojejunostomy in one of nine tertiary centres between 2012 and 2015 were randomly assigned to a development or validation cohort in a 2 : 1 ratio. A model predicting severe PHBL (International Study Group of Liver Surgery grade B/C) was developed and further validated. RESULTS: A total of 2218 procedures were included. PHBL of any severity and severe PHBL occurred in 141 (6·4 per cent) and 92 (4·1 per cent) patients respectively. In the development cohort (1475 patients), multivariable analysis identified blood loss of at least 500 ml, liver remnant ischaemia time 45 min or more, anatomical resection including segment VIII, transection along the right aspect of the left intersectional plane, and associating liver partition and portal vein ligation for staged hepatectomy as predictors of severe PHBL. A risk score (ranging from 0 to 5) was built using the development cohort (area under the receiver operating characteristic curve (AUROC) 0·79, 95 per cent c.i. 0·74 to 0·85) and tested successfully in the validation cohort (AUROC 0·70, 0·60 to 0·80). A score of at least 3 predicted an increase in severe PHBL (19·4 versus 2·6 per cent in the development cohort, P < 0·001; 15 versus 3·1 per cent in the validation cohort, P < 0·001). CONCLUSION: The present risk score reliably predicts severe PHBL. It represents a multi-institutionally validated prognostic tool that can be used to identify a subset of patients at high risk of severe PHBL after elective hepatectomy.

RESUMO

PURPOSE: Management of infected abdominal wall defects is a subject of debate, and the use of prosthetic mesh repair is not recommended due to the dramatic rate of mesh infection. The aim of this prospective study was to determine the recurrence rate and long-term outcomes of repairing infected abdominal wall defects using the Strattice porcine acellular dermal matrix reinforcement through a single-stage surgical approach. METHODS: From August 2010 to May 2012, consecutive patients treated for infected abdominal wall defects using Strattice, a biologic prosthesis, were enrolled. All data were collected prospectively and all patients were followed for physical examination and CT scan evaluation. The primary outcome measure was the recurrence rate. RESULTS: Eighteen patients were enrolled and 14 were evaluable. Of these, eight patients had mesh infections and six had enterocutaneous fistulas. Median follow-up was 13 months (range, 3-22) and median length of hospitalization was 13 days (range, 4-56). The Strattice was placed in the intraperitoneal underlay position in 12 patients, and in the retro-rectus position for two. Post-operative complications included skin dehiscence (n = 3), wound infection (n = 2), skin necrosis (n = 1), and seroma (n = 2). At the end of follow-up, six patients (43 %) experienced abdominal wall defect recurrence. CONCLUSIONS: The utility of biologic prostheses to repair infected abdominal wall defects is controversial; however, currently, they remain the only alternative to a two-staged surgery. Prospective, randomized studies in larger populations of patients are necessary to fully determine the usefulness of biologic prostheses in this setting.

RESUMO

Our aim was to determine preoperative aerobic capacity (oxygen uptake [V'O2 ]) and prevalence of exercise oscillatory ventilation (EOV), underlying clinical characteristics of patients with EOV, and significance of reduced aerobic capacity and EOV in predicting mortality after liver transplantation. We prospectively studied 263 patients who underwent elective liver transplantation. Patients were followed up for 1 year. Despite minor impairment of resting cardiopulmonary function, preoperative aerobic capacity was reduced (peak V'O2 : 64 ± 19% predicted). EOV occurred in 10% of patients. Model for End-Stage Liver Disease score tended to be higher in patients with EOV compared to patients without, but failed to reach significance (p = 0.09). EOV patients had lower peak V'O2 and higher ventilatory drive. EOV was more frequent in nonsurvivors than in survivors (30% vs. 9%, p = 0.01) and was independently associated with posttransplant all-cause 1-year mortality. Reduced peak V'O2 best predicted the primary composite endpoint defined as 1-year mortality and/or prolonged hospitalization and early in-hospital mortality. Multivariate analysis revealed EOV (χ(2), 3.96; p = 0.04) and V'O2 (χ(2), 4.28; p = 0.04) as independent predictors of mortality and so-called primary composite endpoint, respectively. EOV and reduced peak V'O2 may identify high-risk candidates for liver transplantation, which would motivate a more aggressive treatment when detected.

RESUMO

INTRODUCTION: Gallbladder carcinoma is frequently discovered incidentally on pathologic examination of the specimen after laparoscopic cholecystectomy (LC) performed for presumed "benign" disease. The objective of the present study was to assess the role of excision of port-sites from the initial LC for patients with incidental gallbladder carcinoma (IGBC) in a French registry. METHODS: Data on patients with IGBC identified after LC between 1998 and 2008 were retrospectively collated in a French multicenter database. Among those patients undergoing re-operation with curative intent, patients with port-site excision (PSE) were compared with patients without PSE and analyzed for differences in recurrence patterns and survival. RESULTS: Among 218 patients with IGBC after LC (68 men, 150 women, median age 64 years), 148 underwent re-resection with curative intent; 54 patients had PSE and 94 did not. Both groups were comparable with regard to demographic data (gender, age > 70, co-morbidities), surgical procedures (major resection, lymphadenectomy, main bile duct resection) and postoperative morbidity. In the PSE group, depth of tumor invasion was T1b in six, T2 in 24, T3 in 22, and T4 in two; this was not significantly different from patients without PSE (P = 0.69). Port-site metastasis was observed in only one (2%) patient with a T3 tumor who died with peritoneal metastases 15 months after resection. PSE did not improve the overall survival (77%, 58%, 21% at 1, 3, 5 years, respectively) compared to patients with no PSE (78%, 55%, 33% at 1, 3, 5 years, respectively, P = 0.37). Eight percent of patients developed incisional hernia at the port-site after excision. CONCLUSION: In patients with IGBC, PSE was not associated with improved survival and should not be considered mandatory during definitive surgical treatment.

RESUMO

Hepatic artery (HA) rupture after liver transplantation is a rare complication with high mortality. This study aimed to review the different managements of HA rupture and their results. From 1997 to 2007, data from six transplant centers were reviewed. Of 2649 recipients, 17 (0.64%) presented with HA rupture 29 days (2-92) after transplantation. Initial management was HA ligation in 10 patients, reanastomosis in three, aorto-hepatic grafting in two and percutaneous arterial embolization in one. One patient died before any treatment could be initiated. Concomitant biliary leak was present in seven patients and could be subsequently treated by percutaneous and/or endoscopic approaches in four patients. Early mortality was not observed in patients with HA ligation and occurred in 83% of patients receiving any other treatment. After a median follow-up of 70 months, 10 patients died (4 after retransplantation), and 7 patients were alive without retransplantation (including 6 with HA ligation). HA ligation was associated with better 3-year survival (80% vs. 14%; p=0.002). Despite its potential consequences on the biliary tract, HA ligation should be considered as a reasonable option in the initial management for HA rupture after liver transplantation. Unexpectedly, retransplantation was not always necessary after HA ligation in this series.

RESUMO

BACKGROUND: Inevitable hepatitis C virus recurrence after liver transplantation, a major barrier to survival of the transplanted liver may be promoted by immunosuppression and by CD4(+)CD25(+) regulatory T cells (Treg). Treg cells are essential for the induction and maintenance of immunologic self-tolerance as well as transplant tolerance. Moreover, we have previously described low doses of cyclosporine (CsA) to inhibit Treg activity by inducing interleukin-2 and interfron-γ. We investigated here in, the effect of mycophenolate mofetil (MMF) and corticosteroids, usually used in combination with a calcineurin inhibitor on human CD4(+)CD25(+) Treg cells. METHODS: Human CD4(+)CD25(+) cells isolated from healthy donors were cultured in the presence of CsA +/- corticoids or MMF. Suppressive activity of regulatory T cells was assessed in mixed leukocyte reactions including CD25(+) solvents with autologous activated peripheral blood mononuclear cells (PBMC). RESULTS: MMF and dexamethasone inhibited PBMC and Treg proliferation in dose-dependent fashing, maintaining the suppressive activity of Treg cells. However, the association of corticoids with CsA could not reverse the inhibitory effects of CsA on Treg activity, unlike the MMF and CsA combination. CONCLUSION: We have previously shown CsA to significantly impair the function of CD4(+)CD25(+) Treg cells. Herein we reports that corticoids were not able to reverse this effect, whereas MMF couterbalanced it, suggesting that the combination of MMF with CsA maintains regulatory T cells activity promoting tolerance.

RESUMO

BACKGROUND: Hepatocellular carcinoma in noncirrhotic liver (NC-HCC) presents usually with large size, which is seen as a contraindication to liver transplantation (LT) or even resection. The objective of our single-center study was to identify prognostic factors following resection of large NC-HCCs and to subsequently devise a treatment strategy (including LT) in selected patients. METHODS: From 2000 to 2010, 89 patients who had hepatic resection for NC-HCC (large ≥ 8 cm in 52) were analyzed with regard to pathological findings, postoperative and long-term outcome. RESULTS: Five patients died postoperatively. After a mean follow-up of 35 ± 30 months, NC-HCC recurred in 36 patients (26/47 survivors in group 8 cm+, 10/37 in group 8 cm-; p = 0.007). Five-year overall (OS) and disease-free survival (DFS) rates were significantly worse for group 8 cm+ (43.4% vs. 89.2% and 39.3% vs. 60.7% for group 8 cm-, p < 0.05). Seven patients underwent re-hepatectomy and/or LT for isolated intrahepatic recurrence, with 5-year DFS of 57.1%. In a multivariate analysis, the factors associated with poor OS and DFS were vascular invasion and tumor size ≥ 8 cm in the overall population and vascular invasion, fibrosis and satellite nodules in group 8 cm+. Adjuvant transarterial chemotherapy was a protective factor in group 8 cm+. In 22 isolated NC-HCC cases with no vascular invasion or fibrosis, tumor size had no impact on five-year DFS (85%). CONCLUSIONS: Although patients with NC-HCC ≥ 8 cm had a poorer prognosis, the absence of vascular invasion or fibrosis was associated with excellent survival, regardless of the tumor size. In recurrent patients, aggressive treatment (including LT) can be considered.

RESUMO

Obesity has become a major public health concern. More and more patients with substantial obesity require surgery including complex hepatobiliary interventions. The morphology of these patients can make surgery difficult, especially in terms of exposure. We report the case of an obese patient who required a left hemihepatectomy for colorectal liver metastasis. It was very difficult to obtain adequate exposure; this problem was solved by transcutaneous introduction of the handle of a broad costal margin retractor. We describe this maneuver, which allowed us to carry out the intervention under excellent conditions.

RESUMO

BACKGROUND: Preoperative measurement of hepatic venous pressure gradient (HVPG) is not performed routinely before hepatectomy in patients with cirrhosis, although it has been suggested to be useful. This study investigated whether preoperative HVPG values and indirect criteria of portal hypertension (PHT) predict the postoperative course in these patients. METHODS: Between January 2007 and December 2009, consecutive patients with resectable hepatocellular carcinoma (HCC) in a cirrhotic liver were included in this prospective study. PHT was assessed by transjugular HVPG measurement and by classical indirect criteria (oesophageal varices, splenomegaly and thrombocytopenia). The main endpoints were postoperative liver dysfunction and 90-day mortality. RESULTS: Forty patients were enrolled. A raised HVPG was associated with postoperative liver dysfunction (median 11 and 7 mmHg in those with and without dysfunction respectively; P = 0·017) and 90-day mortality (12 and 8 mmHg in those who died and survivors respectively; P = 0·026). Oesophageal varices, splenomegaly and thrombocytopenia were not associated with any of the endpoints. In multivariable analysis, body mass index, remnant liver volume ratio and preoperative HVPG were the only independent predictors of postoperative liver dysfunction. CONCLUSION: An increased HVPG was associated with postoperative liver dysfunction and mortality after liver resection in patients with HCC and liver cirrhosis, whereas indirect criteria of PHT were not. This study suggests that preoperative HVPG measurement should be measured routinely in these patients.

RESUMO

BACKGROUND: Sorafenib increases median survival and time to radiological progression in patients with advanced hepatocellular carcinoma, but its benefit for Child-Pugh B patients remains uncertain. AIM: To evaluate the safety and efficacy of sorafenib in real-life clinical practice conditions and to assess the influence of Child-Pugh class B on safety and efficacy. METHODS: All patients treated with sorafenib for advanced hepatocellular carcinoma in our institution were included prospectively. Adverse events, overall survival and time to progression were recorded. A case control study was performed to compare outcome of patients with comparable stages of hepatocellular carcinoma, but a different Child-Pugh class. RESULTS: From March 2007 to May 2009, 120 patients were included. Overall survival was 11.1 months, Child-Pugh A patients (n=100) had significantly higher median survival than Child-Pugh B patients (n=20) (13 vs. 4.5 months, P=0.0008). In multivariate analysis, Child-Pugh class B, α-fetoprotein level and total size of lesions were independent predictive factors of death. Patients with radiological progression in the first 3 months had shorter median survival (5.4 vs. 17.4 months). In a case control study, time to symptomatic progression (2.5 vs. 3.6 months), frequency of adverse events and discontinuation of sorafenib were not correlated with Child-Pugh class. CONCLUSIONS: Patients with advanced hepatocellular carcinoma treated with sorafenib had a median survival of 11 months. Sorafenib therapy must be considered with caution in Child-Pugh B patients due to their poor survival. Radiological assessment of tumour progression at an early stage may be advantageous when tailoring sorafenib therapy.

RESUMO

BACKGROUND: Studies that compare laparoscopic to open liver resection for hepatocellular carcinoma (HCC) in cirrhotic patients are rare and may have suffered from low patient numbers. This work was designed to determine the impact of laparoscopic resection on postoperative and long-term outcomes in a large series of cirrhotic patients with hepatocellular carcinoma (HCC) compared with open resection. METHODS: From 2002 to 2009, 36 patients with chronic liver disease with complicating HCC were selected for laparoscopic resection (laparoscopic group, LG). The outcomes were compared with those of 53 patients who underwent open hepatectomy (open group, OG) during the same period in a matched-pair analysis. The two groups were similar in terms of tumor number and size and number of resected segments. RESULTS: Morbidity and mortality rates were similar in the two groups (respectively 25 and 0% in LG vs. 35.8 and 7.5% in OG; p = 0.3). Severe complications were more frequent in OG (13.2%) than in LG (2.8%; p = 0.09). Despite similar portal hypertension levels, complications related to ascites (namely evisceration or variceal bleeding) were fatal in 4 of 12 affected patients in OG but 0 of 5 cases in LG (p = 0.2). The mean hospitalization durations were 6.5 ± 2.7 days and 9.5 ± 4.8 days in LG and OG, respectively (p = 0.003). The surgical margins were similar in the two groups. Although there was a trend toward better 5-year overall survival in LG (70 vs. 46% in OG; p = 0.073), 5-year disease-free survival was similar (35.5 vs. 33.6%). CONCLUSIONS: Laparoscopic resection of HCC in patients with chronic liver disease has similar results to open resection in terms of postoperative outcomes, surgical margins, and long-term survival.

RESUMO

Liver metastases from endocrine tumors can reduce 5-year survival from 90% to 40% and, in cases of functional gastrointestinal endocrine tumors, lead to a carcinoid syndrome. Complete resection of cancerous disease should be considered in all cases. Indeed, after hepatectomy, prolonged survival (41-86% at five years) can be achieved, with low rates of surgery-related mortality (0-6.7%). Extended liver resection is required in most cases. Percutaneous portal embolization increases the volumetric feasibility of resection, and sequential hepatectomy techniques enable a two-stage resection of both bilobar metastases and the primary tumor. For carcinoid syndrome that does not respond to medical therapy, incomplete resection of liver metastases, by reducing tumor volume, may be indicated to reduce symptoms and halt the progression of carcinoid heart disease. In cases of non-resectable liver metastases in selected patients, liver transplantation can lead to 5-year survival rates as high as 77%.
