RESUMEN

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.

RESUMEN

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.

RESUMEN

PURPOSE: Best clinical management of severe caustic injury is still a subject of debate. Most surgical teams consider severe caustic injury as an indication for emergency surgery. But, under certain circumstances, conservative management is feasible, avoids the need for gastrectomy, and has a low mortality rate. Postponed reconstructive surgery is usually performed several months after caustic ingestion to restore intestinal continuity or to treat stricture sequelae. This study aimed to investigate long-term nutritional and quality of life (QoL) outcomes after reconstructive surgery for high-grade esophageal and gastric caustic injury. METHODS: Twenty-one patients were assessed for biological and nutritional parameters, physical findings, and quality of life surveys at least 25 months after reconstructive surgery among patients who have required emergency surgery (n = 10) and patients who did not undergo emergency surgery (n = 11). RESULTS: After median follow-up of 74 months (after caustic ingestion) and 67 months (after reconstructive surgery), patients who avoided emergency surgery experienced faster oral diet resumption (49 vs. 157 days, p = 0.004), less weight loss (0.3 vs. 20 kg, p = 0.002), greater body fat percentage (22 vs. 18 %, p = 0.046), better nutritional and physical status (SF12 PCS 51 vs. 43, p = 0.036), and less trouble eating (EORTC QLQ-OG 25 31 vs. 56, p = 0.01). CONCLUSIONS: Our study is the first to evaluate long-term nutritional and QoL outcomes, following severe caustic injury. It demonstrates better long-term nutritional outcomes and QoL in patients suitable for initial conservative management. These results support full functional recuperation of spared organs, even severely burned. In the absence of clinical or biological signs necessitating immediate surgery, conservative management should be advocated.

RESUMEN

BACKGROUND: Perioperative FOLFOX4 (oxaliplatin plus 5-fluorouracil/leucovorin) chemotherapy is the current standard in patients with resectable metastases from colorectal cancer (CRC). We aimed to determine whether a sequential chemotherapy with dose-dense oxaliplatin (FOLFOX7) and irinotecan (FOLFIRI; irinotecan plus 5-fluorouracil/leucovorin) is superior to FOLFOX4. The chemotherapy timing was not imposed, and was perioperative or postoperative. PATIENTS AND METHODS: In this open-label, phase III trial, patients with resectable or resected metastases were randomly assigned either to 12 cycles of FOLFOX4 (oxaliplatin 85 mg/m(2)) or 6 cycles of FOLFOX7 (oxaliplatin 130 mg/m(2)) followed by 6 cycles of FOLFIRI (irinotecan 180 mg/m(2)). Randomization was done centrally, with stratification by chemotherapy timing, type of local treatment (surgery versus radiofrequency ablation with/without surgery), and Fong's prognostic score. The primary end point was 2-year disease-free survival (DFS). RESULTS: A total of 284 patients were randomized, 142 in each treatment group. Chemotherapy was perioperative in 168 (59.2%) patients and postoperative in 116 (40.8%) patients. Perioperative chemotherapy was preferentially proposed for synchronous metastases, whereas postoperative chemotherapy was more frequently used for metachronous metastases. Two-year DFS was 48.5% in the FOLFOX4 group and 50.0% in the FOLFOX7-FOLFIRI group. In the multivariable analysis, more than one metastasis [hazard ratio (HR) = 2.15] and synchronous metastases (HR = 1.63) were independent prognostic factors for shorter DFS. Five-year overall survival (OS) rate was 69.5% with FOLFOX4 versus 66.6% with FOLFOX7-FOLFIRI. CONCLUSIONS: FOLFOX7-FOLFIRI is not superior to FOLFOX4 in patients with resectable metastatic CRC. Five-year OS rates observed in both groups are the highest ever reported in this setting, possibly reflecting the pragmatic approach to chemotherapy timing. CLINICAL TRIALS NUMBER: NCT00268398.

RESUMEN

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.

RESUMEN

OBJECTIVES: In France, organ donation refusal rates approach 32% of eligible brain deaths. Outright family refusal represents the primary barrier reason for declining organ donation. This retrospective study evaluated factors influencing this decision. MATERIAL AND METHODS: A retrospective chart review at Lille Hospital, France, was conducted on brain-death patients eligible for organ donation between 2010 and 2011. Data were collected regarding patient characteristics, death conditions and reasons for refusal based upon family interview. Descriptive statistic analyses were conducted to identify circumstances associated with family refusal. RESULTS: Of 227 eligible organ donors identified, 70 families (30.8%) refused organ donation. The most frequent reason for refusal was desire to keep the body's wholeness (46.3%), followed by religion (16.4%), mistrust of the medical community (13.4%), and revolt against society (6%). The most common causes of death associated with refusal were brutality and suddenness of death (44.8%), early age (23.9%), denial of death (17.9%), and the family culpability (11.9%). In 30% of cases, the family followed the deceased's wishes before his death. CONCLUSION: Family refusal remains a significant factor associated with the approximately one third of declined eligible organ donations. This retrospective analysis suggested that the most important cause for refusal was a desire to keep the body's wholeness, and the brutality and suddenness of the potential donor's death. Additional research addressing these factors, and their underlying causes, paired with measures to improve professional training and public awareness are warranted to improve organ donation rates.

RESUMEN

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.

RESUMEN

BACKGROUND: Indications for preoperative biliary drainage (PBD) in the context of hepatectomy for hilar malignancies are still debated. The aim of this study was to investigate current European practice regarding biliary drainage before hepatectomy for Klatskin tumours. METHODS: This was a retrospective analysis of all patients who underwent formal or extended right or left hepatectomy for hilar cholangiocarcinoma between 1997 and 2008 at 11 European teaching hospitals, and for whom details of serum bilirubin levels at admission and at the time of surgery were available. PBD was performed at the physicians' discretion. The primary outcome was 90-day mortality. Secondary outcomes were morbidity and cause of death. The association of PBD and of preoperative serum bilirubin levels with postoperative mortality was assessed by logistic regression, in the entire population as well as separately in the right- and left-sided hepatectomy groups, and was adjusted for confounding factors. RESULTS: A total of 366 patients were enrolled; PBD was performed in 180 patients. The overall mortality rate was 10·7 per cent and was higher after right- than left-sided hepatectomy (14·7 versus 6·6 per cent; adjusted odds ratio (OR) 3·16, 95 per cent confidence interval 1·50 to 6·65; P = 0·001). PBD did not affect overall postoperative mortality, but was associated with a decreased mortality rate after right hepatectomy (adjusted OR 0·29, 0·11 to 0·77; P = 0·013) and an increased mortality rate after left hepatectomy (adjusted OR 4·06, 1·01 to 16·30; P = 0·035). A preoperative serum bilirubin level greater than 50 µmol/l was also associated with increased mortality, but only after right hepatectomy (adjusted OR 7·02, 1·73 to 28·52; P = 0·002). CONCLUSION: PBD does not affect overall mortality in jaundiced patients with hilar cholangiocarcinoma, but there may be a difference between patients undergoing right-sided versus left-sided hepatectomy.

RESUMEN

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.

RESUMEN

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.

RESUMEN

STUDY OBJECTIVE: It has been demonstrated that mortality following pancreatectomy is correlated with surgical volume. However, up until now, no French study has focused on predictive factors to undergo pancreatectomy in low-volume centers. The objective of this study is to analyze the clinical characteristics, socio-economic status and medical density according to surgical volume and to analyze predictive factors for undergoing pancreatectomy in low-volume centers. PATIENTS AND METHODS: All patients who underwent pancreatectomy in France from 2012 to 2015 were identified fromthe PMSI database. Hopsitals were classified as low, intermediate and high volume (<10, 11-19, ≥20 resections/year, respectively). Clinical and socioeconomic data, travel distance and rurality were assesed to identify factors associated with undergoing pancreatectomy at low-volume hospitals. RESULTS: In overall, 12,333 patients were included. Those who underwent pancreatectomy in low-volume centers were more likely older, had high Charlson comorbidity index (CCI), had low socioeconomic status, and resided in rural locations.distance traveled by patients operated on in low-volume centers was significantly shorter (23 vs. 61km, P<0.001). In multivariable analysis, older age (P=0.04), CCI≥4 (P=0.008), short travel distance (P<0.001), low socio-economic status (P<0.001) and rurality (P<0.001) were associated withundergoing pancreatectomy in low-volume centers. CONCLUSION: Patients continue to undergo pancreatectomy at low-volume hospitals is due not only to clinical parameters, but also to socioeconomic and environmental factors. These factors should be taken into account in process of pancreatic surgery centralization.

RESUMEN

OBJECTIVES: Postoperative infections occur frequently after pancreaticoduodenectomy, especially in patients with bile colonization. Recommendations for perioperative anti-infectious treatment are lacking, and clinical practice is heterogenous. We have analyzed the effects of bile colonization and antibiotic prophylaxis on postoperative infection rates, types and therapeutic consequences. METHODS: Retrospective observational study in patients undergoing pancreaticoduodenectomy with intraoperative bile culture. Data on postoperative infections and non-infectious complications, bile cultures and antibiotic prophylaxis adequacy to biliary bacteria were collected. RESULTS: Among 129 patients, 53% had a positive bile culture and 23% had received appropriate antibiotic prophylaxis. Postoperative documented infection rate was over 40% in patients with or without bile colonization, but antibiotic therapy was more frequent in positive bile culture patients (77% vs. 57%, P=0,008). The median duration of antibiotic therapy was 11 days and included a broad-spectrum molecule in 42% of cases. Two-thirds of documented postoperative infections involved one or more bacteria isolated in bile cultures, which was associated with a higher complication rate. While bile culture yielded Gram-negative bacilli (57%) and Gram-positive cocci (43%), fungal microorganisms were scarce. Adequate preoperative antibiotic prophylaxis according to bile culture was not associated with reduced infectious or non-infectious complication rates. CONCLUSION: Patients undergoing pancreaticoduodenectomy experience a high rate of postoperative infections, often involving bacteria from perioperative bile culture when positive, with no preventive effect of an adequate preoperative antibiotic prophylaxis. Increased postoperative complications in patients with bile colonization may render necessary a perioperative antibiotic treatment targeting bile microorganisms. Further prospective studies are needed to improve the anti-infectious strategy in these patients.

RESUMEN

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%.

RESUMEN

Neoplastic gallbladder polyps (NGP) are rare; the prevalence in the overall population is less than 10%. NGP are associated with a risk of malignant degeneration and must be distinguished from other benign gallbladder polypoid lesions that occur more frequently. NGP are adenomas and the main risk associated with their management is to fail to detect their progression to gallbladder cancer, which is associated with a particular poor prognosis. The conclusions of the recent European recommendations have a low level of evidence, based essentially on retrospective small-volume studies. Abdominal sonography is the first line study for diagnosis and follow-up for NGP. To prevent the onset of gallbladder cancer, or treat malignant degeneration in its early phases, all NGP larger than 10mm, or symptomatic, or larger than 6mm with associated risk factors for cancer (age over 50, sessile polyp, Indian ethnicity, or patient with primary sclerosing cholangitis) are indications for cholecystectomy. Apart from these situations, simple sonographic surveillance is recommended for at least five years; if the NGP increases in size by more than 2mm in size, cholecystectomy is indicated. Laparoscopic cholecystectomy is possible but if the surgeon feels that the risk of intra-operative gallbladder perforation is high, conversion to laparotomy should be preferred to avoid potential intra-abdominal tumoral dissemination. When malignant NGP is suspected (size greater than 15mm, signs of locoregional extension on imaging), a comprehensive imaging workup should be performed to search for liver extension: in this setting, radical surgery should be considered.

Withdrawal of calcineurin inhibitors (CNI) followed by mycophenolate mofetil (MMF) monotherapy after liver transplantation (LT) remains controversial due to the increased risk of acute rejection and graft loss. The aim of the present study, performed in a large cohort of liver-transplanted patients with severe CNI-induced side effects, was to assess renal function recovery, and safety in terms of liver function, of complete CNI withdrawal and replacement by MMF monotherapy. Fifty-two patients treated with MMF monotherapy for CNI-induced toxicity were analyzed. Mean estimated glomerular filtration rate (eGFR) increased significantly during the period of MMF monotherapy, from 37 +/- 10 to 44.7 +/- 15 mL/min/1.73 m(2) at 6 months (p = 0.001) corresponding to a benefit of +17.4% in renal function. eGFR stabilized or improved in 86.5%, 81% and 79% of cases, and chronic renal dysfunction worsened in 13.5%, 19% and 21% of cases, at 6, 12 and 24 months after CNI withdrawal, respectively. Only two patients experienced acute rejection. MMF monotherapy may be efficient at reversing/stabilizing CRD, and appears relatively safe in terms of liver graft function in long-term liver-transplanted patients. However, clinicians must bear in mind the potential risk of rejection and graft loss, and should be very cautious in the management of such 'difficult-to-treat patients'.

RESUMEN

While the natural history and appropriate diagnostic and management practices are relatively well defined for hepatocellular carcinoma (HCC), data are scarce concerning the characteristic features and treatment modalities for recurrent HCC after liver transplantation. The time of recurrence appears to impact survival more significantly than localization, but to date, guidelines for therapeutic management of recurrent HCC have not been established. Data in the literature shows that late and unifocal recurrence has a better prognosis when treated by surgery or radiofrequency. In the event of early recurrence, surgery cannot be recommended due to the lack of evidence and the high risk of advanced disease. Systemic therapy can be discussed in a situation of multifocal recurrence. Proliferative signal inhibitors exhibit both immunosuppressive and antiproliferative properties and liver transplantation teams tend to introduce such treatment despite the lack of extensive data.

RESUMEN

Dermoid cysts involving the diaphragm are rare and their symptomatology is non-specific. CT is the principal diagnostic tool, but it may fail to distinguish whether a cyst is located above, below, or within the diaphragm. Surgical excision of dermoid cysts is recommended because of the possibility of malignant degeneration.

RESUMEN

BACKGROUND: To determine whether the timing of removal of abdominal drainage (AD) after pancreatoduodenectomy (PD) influences the 30-day surgical site infection (30-day SSI) rate. METHODS: A multicenter randomized, intention-to-treat trial with two parallel arms (superiority of early vs. standard AD removal on SSI) was performed between 2011 and 2015 in patients with no pancreatic fistula (PF) on POD3 after PD (NCT01368094). The primary endpoint was the 30-day SSI rate. The secondary endpoints were specific post-PD complications (grade BC PF), postoperative morbidity and risk factor of SSI, reoperation rate, 30-day mortality, length of drainage, length of stay and postoperative infectious complications. RESULTS: One hundred and forty-one patients were randomized: 71 in the early arm, 70 in the standard arm (70.2% of pancreatic adenocarcinomas; 91.5% of pancreatojejunostomies; 66.0% of bilateral drainages; feasibility: 39.9%). Early removal of drains was not associated with a significant decrease of 30-day SSI (14.1% vs. 24.3%, P=0.12). A lower rate of deep SSI was observed in the early arm (2.8% vs. 17.1%, P=0.03), leading to a shorter length of stay (17.8±6.8 vs. 21.0±6.1, P=0.01). Grade BC PF rate (5.6%), severe morbidity (17.7%), reoperation rate (7.8%), 30-day mortality (1.4%) and wound-SSI rate (7.8%) were similar between arms. After multivariate analysis, the timing of AD removal was not associated with an increase of 30-day SSI (OR=0.74 [95% CI 0.35-1.13, P=0.38]). CONCLUSION: In selected patients with no PF on POD3, early removal of abdominal drainage does not seem to increase or decrease surgical site infection's occurrence.

RESUMEN

Liver transplantation (LTx) for metastatic endocrine tumors (MET) remains controversial due to the lack of clear selection criteria. From 1989 to 2005, 85 patients underwent LTx for MET. The primary tumor was located in the pancreas or duodenum in 40 cases, digestive tract in 26 and bronchial tree in five. In the remaining 14 cases, primary location was undetermined at the time of LTx. Hepatomegaly (explanted liver > or =120% of estimated standard liver volume) was observed in 53 patients (62%). Extrahepatic resection was performed concomitantly with LTx in 34 patients (40%), including upper abdominal exenteration (UAE) in seven. Postoperative in-hospital mortality was 14%. Overall 5-year survival was 47%. Independent factors of poor prognosis according to multivariate analysis included UAE (relative risk (RR): 3.72), primary tumor in duodenum or pancreas (RR: 2.94) and hepatomegaly (RR: 2.63). After exclusion of cases involving concomitant UAE, the other two factors were combined into a risk model. Five-year survival rate was 12% for the 23 patients presenting both unfavorable prognostic factors versus 68% for the 55 patients presenting one or neither factor (p < 10(-7)). LTx can benefit selected patients with nonresectable MET. Patients presenting duodeno-pancreatic MET in association with hepatomegaly are poor indications for LTx.
