Prognostic risk factors in 113 patients undergoing cephalic duodenopancreatectomy for distal cholangiocarcinoma. GASTROENTEROLOGIA Y HEPATOLOGIA 2024; 47:448-456. [PMID: 37827384 DOI: 10.1016/j.gastrohep.2023.09.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/05/2023] [Revised: 06/25/2023] [Accepted: 09/22/2023] [Indexed: 10/14/2023]
Abstract
INTRODUCTION Distal cholangiocarcinoma is a malignant epithelial neoplasia that affects the extrahepatic bile ducts, below the cystic duct. No relevant relationship between perioperative factors and worse long-term outcome has been proved. OBJECTIVE To analyze the risk factors for mortality and long-term recurrence of distal cholangiocarcinoma in resected patients. MATERIALS AND METHODS A single-center prospective database of patients operated on for distal cholangiocarcinoma between 1990 and 2021 was analyzed in order to investigate mortality and recurrence factors. RESULTS One hundred and thirteen patients have undergone surgery, with mean actuarial survival of 100.2 (76-124) months after resection. The bivariate study did not show differences between patients depending on age or preoperative variables studied. When multivariate analysis was performed, the presence of affected adenopathy was a risk factor for long-term mortality. The presence of affected lymph nodes, tumor recurrence, and biliary fistula during the postoperative period implied worse actuarial survival when comparing the Kaplan-Meier curves. CONCLUSIONS The presence of affected lymph nodes influence the prognosis of the disease. The occurrence of biliary fistula during postoperative cholangiocarcinoma distal could aggravate long-term outcomes, a finding that should be reaffirmed in future studies.

The involvement of the hepatic artery is a risk factor for unresectability after neoadjuvant treatment in borderline pancreatic adenocarcinoma. Surg Oncol 2024; 52:102027. [PMID: 38113726 DOI: 10.1016/j.suronc.2023.102027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2023] [Revised: 11/27/2023] [Accepted: 12/05/2023] [Indexed: 12/21/2023]
Abstract
INTRODUCTION Borderline Resectable Pancreatic Ductal Adenocarcinoma (BR-PDAC) benefits from neoadjuvant treatment (NAT) with the intent of surgical salvage in the absence of disease progression during chemotherapy (CT) or chemoradiotherapy (CRT). Scarce literature exists about prognostic factors of resectability at the time of diagnosis or during neoadjuvant treatment, especially regarding vascular relationships. MATERIALS We reviewed our prospective BR-PDAC cohort to determine resectability predictors. We collected data about clinical baseline characteristics, vessels' involvement, type of NAT, CA19-9 evolution, and radiological outcome. We performed a descriptive analysis and a logistic regression model to define resectability predictors; we finally compared overall survival (OS) and progression-free survival (PFS) for those predictors. RESULTS One hundred patients started NAT, with a resection rate of 44 % (40 pancreaticoduodenectomies, 4 distal pancreatectomies). The most frequent vessel relationship was the abutment of the superior mesenteric artery (44 %), and 26 patients had ≥2 vessels involved. Prognostic factors of resectability were CA19-9 response >10 % (OR 3.07, p = 0.016) and Hepatic Artery involvement (OR 0.21, p = 0.026). Median overall survival was better for CA19-9 responders than for non-responders (20.9 months and 11.8 months respectively, p < 0.001), and similar to normalized CA19-9 (25.0 months, p = 0.48). There were no differences in terms of OS or PFS with the involvement of the HA (17.7 vs 17.1 months, p = 0.367; and 8.7 vs 12.0 months, p = 0.267). CONCLUSION The involvement of the Hepatic Artery seems to confer a worse prognosis regarding resectability. A decrease of only >10 % of CA19-9 is a predictive factor for resectability and better overall and progression-free survival.

Abstract
INTRODUCTION Delayed gastric emptying is one of the most frequent complications after pancreatoduodenectomy. METHODS We performed an analysis of risk factors for delayed gastric emptying on a prospective database of 390 patients operated on between 2013 and 2021. A comparative retrospective study was carried out between patients with and without delayed gastric emptying and subsequently a study of risk factors for delayed gastric emptying using univariate and multivariate logistic regression models. RESULTS The incidence of delayed gastric emptying in the overall series was 28%. The morbidity of the group was 63%, and postoperative mortality was 3.1%. Focusing on delayed gastric emptying, the median age (73 years vs 68 years, P < 0.001) and preoperative creatinine (75 vs 65.5, P < 0.001) were higher in the group with this complication. The study of risk factors showed that age over 60 years (P = 0.002) and pancreatic fistula (P < 0.001) were risk factors for delayed gastric emptying. CONCLUSION The presence of pancreatic fistula is confirmed as a risk factor for slow gastric emptying after pancreaticoduodenectomy. In addition, age over 60 years is shown to be a risk factor for slow gastric emptying.

Experience in the resection of the uncinate process of the pancreas: Indications and results. Literature review. Cir Esp 2023; 101:522-529. [PMID: 36283601 DOI: 10.1016/j.cireng.2022.10.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2022] [Revised: 07/25/2022] [Accepted: 08/21/2022] [Indexed: 06/16/2023]
Abstract
INTRODUCTION The aim of our study is to assess the accumulated experience in the use of uncinatectomy (UC) as a parenchymal-sparing pancreatectomy technique. METHOD We have carried out a observational and descriptive study including restrospectively all the patients undergoing UC at Hospital Universitary de Bellvitge (HUB) and an exhaustive review of the cases described in the english literature. RESULTS From 2003 to 2019, seven patients have been operated by UC in the HUB with a diagnostic orientation of pancreatic lesion considered premalignant. All patients have presented morbidity, mainly in the form of postoperative pancreatic fistula, and none of them have presented endocrine or exocrine pancreatic insufficiency. Currently, all patients are alive and without recurrence of neoplastic disease. Another 29 cases have been described in the literature. Of all the cases (36 patients), the approach was minimally invasive (laparoscopic or robotic) in 6 patients (16.7%), leading to a shorter hospital stay. The global incidence of pancreatic fistula is 50%, with a re-admission rate of less than 10%, but without requiring re-intervention. CONCLUSIONS UC is an infrequent and poorly standardized technique for the resection of benign lesions or those with low potential for malignancy located in the uncinate process of the pancreas. Although it is associated with equal or greater morbidity than standardized resection techniques, it offers excellent preservation of endocrine and exocrine pancreatic function, with the consequent long-term benefit in the patients life quality.

Predictive factors for resection and survival in type A borderline resectable pancreatic ductal adenocarcinoma patients after neoadjuvant therapy: A retrospective cohort study. Medicine (Baltimore) 2022; 101:e32126.

Abstract
INTRODUCTION Pancreatic cancer is the seventh leading cause of cancer-related death worldwide, and surgical resection with radical intent remains the only potentially curative treatment option today. However, borderline resectable pancreatic ductal adenocarcinomas (BR-PDAC) stand in the gray area between the resectable and unresectable disease since they are technically resectable but have a high probability of incomplete exeresis. Neoadjuvant treatment (NAT) plays an important role in ensuring resection success.Different survival prognostic factors for BR-PDAC have been well described, but evidence on the predictive factors associated with resection after NAT is scarce. This study aims to study if CA 19-9 plasmatic levels and the tumor anatomical relationship with neighboring vascular structures are prognostic factors for resection and survival (both Overall Survival and Progression-Free Survival) in patients with type A BR-PDAC. METHODS This will be a retrospective cohort study using data from type A BR-PDAC patients who received NAT in the Bellvitge University Hospital. The observation period is from January 2010 until December 2019; patients must have a minimum 12-month follow-up. Patients will be classified according to the MD Anderson Cancer Center criteria for BR-PDAC. DISCUSSION Patients with BR-PDAC have a high risk for a margin-positive resection. Serum Carbohydrate Antigen 19-9 plasmatic levels and vascular involvement stand out as disease-related prognostic factors.This study will provide valuable information on the prognostic factors associated with resection. We will exclude locally advanced tumors and expect this approach to provide more realistic resection rates without selecting those patients that undergo surgical exploration. However, focusing on an anatomical definition may limit the results' generalizability.

Delayed gastric emptying after classical Whipple or pylorus-preserving pancreatoduodenectomy: a randomized clinical trial (QUANUPAD). Langenbecks Arch Surg 2022; 407:2247-2258. [PMID: 35786739 PMCID: PMC9468034 DOI: 10.1007/s00423-022-02583-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2021] [Accepted: 06/04/2022] [Indexed: 10/29/2022]
Abstract
PURPOSE Pylorus-preserving pancreatoduodenectomy (PPPD) has been the gold standard for pancreatic head lesion resection for several years. Some studies have noted that it involves more delayed gastric emptying (DGE) than classical Whipple (i.e., pancreatoduodenectomy with antrectomy). Our working hypothesis was that the classical Whipple has a lower incidence of DGE. We aimed to compare the incidence of DGE among pancreatoduodenectomy techniques. METHODS This pragmatic, randomized, open-label, single-center clinical trial involved patients who underwent classical Whipple (study group) or PPPD (control group). Gastric emptying was clinically evaluated using scintigraphy. DGE was defined according to the International Study Group of Pancreatic Surgery (ISGPS) criteria. The secondary endpoints were postoperative morbidity, length of hospital stay, anthropometric measurements, and nutritional status. RESULTS A total of 84 patients were randomized (42 per group). DGE incidence was 50% (20/40, 95% confidence interval (95% CI): 35-65%) in the study group and 62% (24/39, 95% CI: 46-75%) in the control group (p = 0.260). No differences were observed between both groups regarding postoperative morbidity or length of hospital stay. Anthropometric measurements at 6 months post-surgery: triceps fold measurements were 12 mm and 16 mm (p = 0.021). At 5 weeks post-surgery, triceps fold measurements were 13 mm and 16 mm (p = 0.020) and upper arm circumferences were 26 cm and 28 cm (p = 0.030). No significant differences were observed in nutritional status. CONCLUSION DGE incidence and severity did not differ between classical Whipple and PPPD. Some anthropometric measurements may indicate a better recovery with PPPD. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT03984734.

Abstract
BACKGROUND There are no clearly defined indications for pancreas-preserving duodenectomy. The present study aimed to analyze postoperative morbidity and the outcomes of patients undergoing pancreas-preserving duodenectomy. METHODS Patients undergoing pancreas-preserving duodenectomy from April 2008 to May 2020 were included. We divided the series according to indication: scenario 1, primary duodenal tumors; scenario 2, tumors of another origin with duodenal involvement; and scenario 3, emergency duodenectomy. RESULTS We included 35 patients. Total duodenectomy was performed in 1 patient of adenomatous duodenal polyposis, limited duodenectomy in 7, and third + fourth duodenal portion resection in 27. The indications for scenario 1 were gastrointestinal stromal tumor (n = 13), adenocarcinoma (n = 4), neuroendocrine tumor (n = 3), duodenal adenoma (n = 1), and adenomatous duodenal polyposis (n = 1); scenario 2: retroperitoneal desmoid tumor (n = 2), recurrence of liposarcoma (n = 2), retroperitoneal paraganglioma (n = 1), neuroendocrine tumor in pancreatic uncinate process (n = 1), and duodenal infiltration due to metastatic adenopathies of a germinal tumor with digestive hemorrhage (n = 1); and scenario 3: aortoenteric fistula (n = 3), duodenal trauma (n = 1), erosive duodenitis (n = 1), and biliopancreatic limb ischemia (n = 1). Severe complications (Clavien-Dindo ≥ IIIb) developed in 14% (5/35), and postoperative mortality was 3% (1/35). CONCLUSIONS Pancreas-preserving duodenectomy is useful in the management of primary duodenal tumors, and is a technical option for some tumors with duodenal infiltration or in emergency interventions.

Abstract
INTRODUCTION Duodenal adenocarcinoma is a rare malignancy. Given the rarity of the disease, there is limited data related to resection results. The objective is to analyze results at our hospital after the curative resection of duodenal adenocarcinoma (DA). METHODS The variables were retrospectively collected from patients operated on between 1990 and 2017 at our hospital. RESULTS A total of 27 patients were treated. Twenty-three patients (85%) underwent pancreaticoduodenectomy, and 4 patients (15%) with tumors located in the third and fourth portions of the duodenum underwent segmental duodenal resection. The overall postoperative morbidity was 67% (18 patients). Postoperative mortality was 7% (2 patients); however, postoperative mortality related to surgery was 4% (1 patient). All patients had negative resection margins. A median of 18 lymph nodes (range, 0-38) were retrieved and evaluated, with a median of 1 involved node (range, 0-8). Median follow up was 23 (9-69.7) months. Actuarial overall survival was 62.2 (25.2-99.1) months. Actuarial disease-free survival was 49 (0-133) months. CONCLUSIONS The surgical treatment of duodenal adenocarcinoma is associated with a high morbidity, although it achieves considerable survival. Depending on the tumor location and if there is no pancreatic infiltration, segmental duodenal resection with negative margins is an alternative to cephalic pancreaticoduodenectomy.

Abstract
BACKGROUND Delayed gastric emptying (DGE) is the most important cause of an extended hospital stay after pancreatoduodenectomy. Reports suggest that a Roux-en-Y gastroenteric anastomosis may have lower incidence of DGE than a Billroth II reconstruction. The primary aim of this RCT was to compare Billroth II (single loop) and Roux-en-Y (double loop) after pancreatoduodenectomy to determine whether Roux-en-Y reconstruction is associated with a lower incidence of DGE. Secondary endpoints were postoperative complications. METHODS This was a randomized unblinded single-centre trial without masked evaluation of the main outcome. Patients undergoing pancreatoduodenectomy between 2013 and 2015 were randomized to undergo one of two types of gastroenteric anastomosis for reconstruction. RESULTS A total of 80 patients were randomized, 40 in each group. The incidence of DGE was the same in patients undergoing Billroth II or Roux-en-Y gastroenteric anastomosis (both 18 of 40 patients; P = 1·000). The grade of DGE was also similar in the Billroth II and Roux-en-Y groups (grade A, both 10 of 40; grade B, 5 of 40 versus 6 of 40; grade C, 3 of 40 versus 2 of 40; P = 0·962). The mortality rate was 3 per cent, with no significant difference between the two groups. There were no differences in the overall rate of postoperative morbidity, relaparotomy rate or duration of hospital stay. CONCLUSION The incidence and severity of DGE does not differ between single- or double-loop gastroenteric anastomosis performed after pancreatoduodenectomy. Registration number: NCT00915863 (http://www.clinicaltrials.gov).

Abstract
INTRODUCTION A borderline resectable group (APBR) has recently been defined in adenocarcinoma of the pancreas. The objective of the study is to evaluate the results in the surgical treatment after neoadjuvancy of the APBR. METHOD Between 2010 and 2014, we included patients with APBR in a neoadjuvant and surgery protocol, staged by multidetector computed tomography (MDCT). Treatment with chemotherapy was based on gemcitabine and oxaliplatin. Subsequently, MDCT was performed to rule out progression, and 5-FU infusion and concomitant radiotherapy were given. MDCT and resection were performed in absence of progression. A descriptive statistical study was performed, dividing the series into: surgery group (GR group) and progression group (PROG group). RESULTS We indicated neoadjuvant treatment to 22 patients, 11 of them were operated, 9 pancreatoduodenectomies, and 2 distal pancreatectomies. Of the 11 patients, 7 required some type of vascular resection; 5 venous resections, one arterial and one both. No postoperative mortality was recorded, 7 (63%) had any complications, and 4 were reoperated. The median postoperative stay was 17 (7-75) days. The pathological study showed complete response (ypT0) in 27%, and free microscopic margins (R0) in 63%. At study clossure, all patients had died, with a median actuarial survival of 13 months (9,6-16,3). The median actuarial survival of the GR group was higher than the PROG group (25 vs. 9 months; p < 0.0001). CONCLUSION The neoadjuvant treatment of APBR allows us to select a group of patients in whom resection achieves a longer survival to the group in which progression is observed. Post-adjuvant pancreatic resection requires vascular resection in most cases.

Abstract
There is a lack of data on incidental hepatocellular carcinoma (iHCC) in the setting of liver transplantation (LT) in human immunodeficiency virus (HIV)-infected patients. This study aims to describe the frequency, histopathological characteristics, and outcomes of HIV+ LT recipients with iHCC from a Spanish multicenter cohort in comparison with a matched cohort of LT patients without HIV infection. A total of 15 (6%) out of 271 patients with HIV infection who received LT in Spain from 2002 to 2012 and 38 (5%) out of the 811 HIV- counterparts presented iHCC in liver explants (P = 0.58). Patients with iHCC constitute the present study population. All patients also had hepatitis C virus (HCV)-related cirrhosis. There were no significant differences in histopathological features of iHCC between the 2 groups. Most patients showed a small number and size of tumoral nodules, and few patients had satellite nodules, microvascular invasion, or poorly differentiated tumors. After a median follow-up of 49 months, no patient developed hepatocellular carcinoma (HCC) recurrence after LT. HIV+ LT recipients tended to have lower survival than their HIV- counterparts at 1 (73% versus 92%), 3 (67% versus 84%), and 5 years (50% versus 80%; P = 0.06). There was also a trend to a higher frequency of HCV recurrence as a cause of death in the former (33% versus 10%; P = 0.097). In conclusion, among LT recipients for HCV-related cirrhosis, the incidence and histopathological features of iHCC in HIV+ and HIV- patients were similar. However, post-LT survival was lower in HIV+ patients probably because of a more aggressive HCV recurrence. Liver Transplantation 23 645-651 2017 AASLD.

Abstract
INTRODUCTION The treatment of patients with non-functioning pancreatic neuroendocrine tumours (NFPNET) is resection in locally pancreatic disease, or with resectable liver metastases. There is controversy about unresectable liver disease. METHODS We analysed the perioperative data and survival outcome of 63 patients who underwent resection of NFPNET between 1993 and 2012. They were divided into 3 scenarios: A, pancreatic resection (44patients); B, pancreatic and liver resection in synchronous resectable liver metastases (12patients); and C, pancreatic resection in synchronous unresectable liver metastases (6patients). The prognostic factors for survival and recurrence were studied. RESULTS Distal pancreatectomy (51%) and pancreaticoduodenectomy (38%) were more frequently performed. Associated surgery was required in 44% of patients, including synchronous liver resections in 9patients. Two patients received a liver transplant during follow-up. According to the WHO classification they were distributed into G1: 10 (16%), G2: 45 (71%), and G3: 8 (13%). The median hospital stay was 11days. Postoperative morbidity and mortality were 49% and 1.6%, respectively. At the closure of the study, 43 (68%) patients were still alive, with a mean actuarial survival of 9.6years. The WHO classification and tumour recurrence were risk factors of mortality in the multivariate analysis. The median actuarial survival by scenarios was 131months (A), 102months (B), and 75months (C) without statistically significant differences. CONCLUSIONS Surgical resection is the treatment for NFPNET without distant disease. Resectable liver metastases in well-differentiated tumours must be resected. The resection of the pancreatic tumour with unresectable synchronous liver metastasis must be considered in well-differentiated NFPNET. The WHO classification grade and recurrence are risk factors of long-term mortality.

Abstract
INTRODUCTION The specific questionnaire Liver Disease Quality of Life (LDQOL) is a valid tool for measuring quality of life (QOL) and has been used to show that liver transplantation (LT), which is an effective treatment for end-stage liver disease, may improve QOL. OBJECTIVES This study aims to identify aspects of QOL that improve after LT and those that do not. PATIENTS AND METHODS Patients accepted for LT were invited to answer the LDQOL at baseline and after transplantation at 6 and 12 months. LDQOL contains the 36-item Short Form Health Survey (SF-36) and 12 specific dimensions. Responsiveness was assessed using the paired Student t test. RESULTS The study included a cohort of 156 patients, 73% males, of an average age of 53 (26-67) years, with the following common indications: tumor (35%), hepatitis C (23%), and alcohol-related (21%) liver disease. Mean scores showed a statistically significant (P < .05) improvement after 1 year in 6 of 8 SF-36 dimensions, in the physical component summary score, and in 7 of 12 disease-specific dimensions. The two dimensions that showed no improvement in the SF-36 dimensions were "social functioning" and "vitality," whereas the specific dimensions to not improve were "sleep problems," "social interaction," "activities of daily living," and "concerns about the future." CONCLUSION Findings suggest that perceived QOL after LT improves but could be further enhanced with the use of specific programs for amending sleep disorders and physical aspects.

Human immunodeficiency virus infection does not worsen prognosis of liver transplantation for hepatocellular carcinoma. Hepatology 2016; 63:488-98. [PMID: 26516761 DOI: 10.1002/hep.28321] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/24/2015] [Accepted: 10/21/2015] [Indexed: 12/19/2022]
Abstract
UNLABELLED The impact of human immunodeficiency virus (HIV) infection on patients undergoing liver transplantation (LT) for hepatocellular carcinoma (HCC) is uncertain. This study aimed to assess the outcome of a prospective Spanish nationwide cohort of HIV-infected patients undergoing LT for HCC (2002-2014). These patients were matched (age, gender, year of LT, center, and hepatitis C virus (HCV) or hepatitis B virus infection) with non-HIV-infected controls (1:3 ratio). Patients with incidental HCC were excluded. Seventy-four HIV-infected patients and 222 non-HIV-infected patients were included. All patients had cirrhosis, mostly due to HCV infection (92%). HIV-infected patients were younger (47 versus 51 years) and had undetectable HCV RNA at LT (19% versus 9%) more frequently than non-HIV-infected patients. No significant differences were detected between HIV-infected and non-HIV-infected recipients in the radiological characteristics of HCC at enlisting or in the histopathological findings for HCC in the explanted liver. Survival at 1, 3, and 5 years for HIV-infected versus non-HIV-infected patients was 88% versus 90%, 78% versus 78%, and 67% versus 73% (P = 0.779), respectively. HCV infection (hazard ratio = 7.90, 95% confidence interval 1.07-56.82) and maximum nodule diameter >3 cm in the explanted liver (hazard ratio = 1.72, 95% confidence interval 1.02-2.89) were independently associated with mortality in the whole series. HCC recurred in 12 HIV-infected patients (16%) and 32 non-HIV-infected patients (14%), with a probability of 4% versus 5% at 1 year, 18% versus 12% at 3 years, and 20% versus 19% at 5 years (P = 0.904). Microscopic vascular invasion (hazard ratio = 3.40, 95% confidence interval 1.34-8.64) was the only factor independently associated with HCC recurrence. CONCLUSIONS HIV infection had no impact on recurrence of HCC or survival after LT. Our results support the indication of LT in HIV-infected patients with HCC.

Abstract
A retrospective cohort multicenter study was conducted to analyze the risk factors for tumor recurrence after liver transplantation (LT) in cirrhotic patients found to have an intrahepatic cholangiocarcinoma (iCCA) on pathology examination. We also aimed to ascertain whether there existed a subgroup of patients with single tumors ≤2 cm ("very early") in which results after LT can be acceptable. Twenty-nine patients comprised the study group, eight of whom had a "very early" iCCA (four of them incidentals). The risk of tumor recurrence was significantly associated with larger tumor size as well as larger tumor volume, microscopic vascular invasion and poor degree of differentiation. None of the patients in the "very early" iCCA subgroup presented tumor recurrence compared to 36.4% of those with single tumors >2 cm or multinodular tumors, p = 0.02. The 1-, 3- and 5-year actuarial survival of those in the "very early" iCCA subgroup was 100%, 73% and 73%, respectively. The present is the first multicenter attempt to ascertain the risk factors for tumor recurrence in cirrhotic patients found to have an iCCA on pathology examination. Cirrhotic patients with iCCA ≤2 cm achieved excellent 5-year survival, and validation of these findings by other groups may change the current exclusion of such patients from transplant programs.

Abstract
BACKGROUND The detection and diagnosis of neuroendocrine tumors (NETs) is challenging. Endoscopic ultrasonography (EUS) has a significant role in the detection of NETs suspected from clinical manifestations or imaging techniques, as well as in their precise localization and cytological confirmation using EUS-Fine-needle aspiration-puncture (FNA). OBJECTIVE To assess the usefulness and precision of EUS-FNAP in the differential diagnosis and confirmation of NETs, in a retrospective review of our experience. PATIENTS AND METHODS in a total of 55 patients with suspected NETs who underwent radial or sectorial EUS, 42 tumors were detected in 40 cases. EUS-FNA using a 22G needle was performed for 16 cases with suspected functional (hormonal disorders: 6 cases) and non-functional NETs (10 cases). Ki 67 or immunocytochemistry (ICC) testing was performed for all.There was confirmation in 9 cases (5 female and 4 male) with a mean age of 51 years (range: 41-81 years).All tumors were located in the pancreas except for one in the mediastinum and one in the rectum, with a mean size of 19 mm (range: 10-40 mm). RESULTS There were no complications attributable to FNA. Sensitivity was 100% and both precision and PPV were 89%, as a false positive result suggested a diagnosis with NET during cytology that surgery finally revealed to be a pancreatic pseudopapillary solid tumor. CONCLUSIONS EUS-FNA with a 22G needle for NETs has high sensitivity and PPV at cytological confirmation with few complications.

Abstract
It is accepted that for achieving a successful liver transplantation one of the most important points is the arterial revascularization of the graft. Sometimes the recipient's hepatic artery is not suitable for anastomosis. In this review, we will discuss the different options to deal with a compromised arterial tree in cadaveric orthotopic liver transplantation with whole graft.

Abstract
PURPOSE To compare the postoperative results of various preservative surgery (PS) techniques with those of two types of pancreatoduodenectomy (PD). METHODS The subjects of this study were 65 patients treated surgically for chronic pancreatitis, or benign or borderline tumors. We defined PS as any of the following: duodenum-preserving pancreatic head resection (DPPHR), uncinatectomy (UC), and cystic tumor enucleation (EN). The two types of PD were Whipple pancreatoduodenectomy (WPD) and pylorus-preserving pancreatoduodenectomy (PPPD). RESULTS Benign lesions were treated with PD in 41 patients and PS in 24 patients. Whipple pancreatoduodenectomy was performed in 17 patients, PPPD in 24, DPPHR in 20, EN in 3, and UC in 1. The main indication for surgery was chronic pancreatitis (66%). Delayed gastric emptying (DGE) was seen in 41% of patients in the PD group but none in the PS group (P = 0.04). However, there were no differences between the two groups in the incidence of pancreatic fistulas or other complications. Reoperation was required in five of the PD patients, but none of the PS patients. CONCLUSION Surgical techniques for preserving pancreatic tissue are effective for carefully selected patients with benign pancreatic disorders.

Abstract
BACKGROUND The use of prophylactic antibiotics in acute severe necrotizing pancreatitis is controversial. METHODS Prospective, randomized, placebo-controlled, double-blind study was carried out at Bellvitge Hospital, in Barcelona, Spain. Among 229 diagnosed with severe acute pancreatitis, 80 had evidence of necrotizing pancreatitis (34/80 patients were excluded of the protocol). Forty-six patients without previous antibiotic treatment with pancreatic necrosis in a contrast-enhanced CT scan were randomly assigned to receive either intravenous ciprofloxacin or placebo. Five patients were secondarily excluded, and the remaining 41 patients were finally included in the study (22 patients received intravenous ciprofloxacin and 19 patients placebo). RESULTS Comparing the 22 with intravenous ciprofloxacin and 19 with placebo, infected pancreatic necrosis was detected in 36% and 42% respectively (p = 0.7). The mortality rate was 18% and 11%, respectively (p = 0.6). No significant differences between both treatment groups were observed with respect to variables such as: non-pancreatic infections, surgical treatment, timing and the re-operation rate, organ failure, length of hospital and ICU stays. CONCLUSION The prophylactic use of ciprofloxacin in patients with severe necrotizing pancreatitis did not significantly reduce the risk of developing pancreatic infection or decrease the mortality rate. The small number of patients included in this study should be considered.

Abstract
BACKGROUND Splanchnic thrombosis is a surgical challenge in liver transplantation (LT). The aim of this study was to analyze our experience in the management of portal vein thrombosis, and its influence on evolution. AIM The aim of this study was to analyze our experience in the management of portal vein thrombosis, and its influence on evolution. PATIENTS AND METHODS Between 1999 and 2004, 366 liver transplants were performed in 335 patients. Forty-two patients [12.5%: portal vein thrombosis (PVT) group] had portal thrombosis at the time of LT. We analyzed the technical aspects and compared their evolution with a group of patients without portal thrombosis (n = 293; no-PVT group). Retransplantations were excluded. RESULTS Of the 42 patients with thrombosis, 18 had partial thrombosis and 16 complete thrombosis [six included the proximal superior mesenteric vein (SMV) and in two the whole splanchnic system]. In 12 cases, usual T-T anastomosis was performed and in 16 cases a thrombectomy was carried out; there were five cases of anastomosis at confluence of the SMV, five cases of anastomosis to a collateral vein, three cases of venous graft, and one case of cavoportal hemitransposition. The operative time was higher in PVT group (417 +/- 103 min vs. 363 +/- 83; p = 0.0005), as RBC transfusion (2.4 +/- 3.1 vs. 1.9 +/- 2.3; p = 0.04), and hospital stay (20.9 +/- 14.9 d vs. 15.1 +/- 10.6; p = 0.002). However, there were no differences in hospital mortality (4% vs. 7.8%; p = 0.98), primary dysfunction (4.8% vs. 7.8%; p = 0.44), or three-yr-actuarial survival (75% vs. 77%; p = 0.95). The incidence of post-transplant thrombosis was higher in the PVT group (15% vs. 2.4%; p = 0.0005). CONCLUSIONS Portal thrombosis is associated with greater operative complexity and rethrombosis, but has no influence on overall morbidity and mortality.

Abstract
INTRODUCTION Surgery that preserves the duodenopancreatic region has become well-established in chronic pancreatitis (CP) and some groups have begun to use these techniques to treat benign tumors and even those with uncertain potential malignancy. However, the technical complexity of this type of intervention may be greater than that of cephalic duodenopancreatectomy and complications may be even more frequent and consequently the indications for these procedures are debated. The aim of this study was to evaluate the experience accumulated at our center over the past few years in the use of pancreatic surgery preserving the duodenopancreatic region (PS). MATERIAL AND METHODS. Between 1996 and 2006, we carried out PS in 24 patients with disease localized in the head of the pancreas. PS was defined as any of the following techniques: resection of the head of the pancreas with duodenal preservation (RHPDP), uncinatectomy (UC) and cystic tumor enucleation (EN). RESULTS RHPDP was performed in 20 patients (83%), UC in 1 (4%) and EN in 3 (13%). Surgery was performed for CP in 11 patients, serous cystoadenoma in 4, intraductal papillary mucinous tumor in 5 and miscellaneous injuries in the four remaining patients. Overall, the series showed 54% morbidity with no post-operative mortality. The median length of postoperative hospital stay was 11 days (7-43). CONCLUSION After analyzing the experience accumulated over the years, showing nil mortality and acceptable morbidity, we believe that the use of these 3 techniques for preserving the pancreatic parenchyma is useful when their suitability is rigorously indicated. Subsequent studies should look in depth at improving quality of life and physiological effects, depending on the technique used.

Abstract
BACKGROUND Cold ischemia time and the presence of postoperative hepatic arterial thrombosis have been associated with biliary complications (BC) after liver transplantation. An ABO-incompatible blood group has also been suggested as a factor for predisposal towards BC. However, the influence of Rh nonidentity has not been studied previously. MATERIALS Three hundred fifty six liver transplants were performed from 1995 to 2000 at our hospital. BC incidence and risk factors were studied in 345 patients. RESULTS Seventy patients (20%) presented BC after liver transplantation. Bile leakage (24/45%) and stenotic anastomosis (21/30%) were the most frequent complications. Presence of BC in Rh-nonidentical graft-host cases (23/76, 30%) was higher than in Rh-identical grafts (47/269, 17%) (P=0.01). BC was also more frequent in grafts with arterial thrombosis (9/25, 36% vs 60/319, 19%; P=0.03) and grafts with cold ischemia time longer than 430 min (26/174, 15% vs 44/171, 26%; P=0.01). Multivariate logistic regression confirmed that Rh graft-host nonidentical blood groups [RR=2(1.1-3.6); P=0.02], arterial thrombosis [RR=2.6(1.1-6.4); P=0.02] and cold ischemia time longer than 430 min [RR=1.8(1-3.2); P=0.02] were risk factors for presenting BC. CONCLUSION Liver transplantation using Rh graft-host nonidentical blood groups leads to a greater incidence of BC.

Abstract
OBJECTIVE To evaluate the efficacy, amount of hemorrhage, biliary leakage, complications, and postoperative evolution after fibrin glue sealant application in patients undergoing liver resection. SUMMARY BACKGROUND DATA Fibrin sealants have become popular as a means of improving perioperative hemostasis and reducing biliary leakage after liver surgery. However, trials regarding its use in liver surgery remain limited and of poor methodologic quality. PATIENTS AND METHODS A total of 300 patients undergoing hepatic resection were randomly assigned to fibrin glue application or control groups. Characteristics and debit of drainage and postoperative complications were evaluated. The amount of blood loss, measurements of hematologic parameters liver test, and postoperative evolution (particularly involving biliary fistula and morbidity) was also recorded. RESULTS Postoperatively, no differences were observed in the amount of transfusion (0.15 +/- 0.66 vs. 0.17 +/- 0.63 PRCU; P = 0.7234) or in the patients that required transfusion (18% vs. 12%; P = 0.2), respectively, for the fibrin glue or control group. There were no differences in overall drainage volumes (1180 +/- 2528 vs. 960 +/- 1253 mL) or in days of postoperative drainage (7.9 +/- 5 vs. 7.1 +/- 4.7). Incidence of biliary fistula was similar in the fibrin glue and control groups, (10% vs. 11%). There were no differences regarding postoperative morbidity between groups (23% vs. 23%; P = 1). CONCLUSIONS Application of fibrin sealant in the raw surface of the liver does not seem justified. Blood loss, transfusion, incidence of biliary fistula, and outcome are comparable to patients without fibrin glue. Therefore, discontinuation of routine use of fibrin sealant would result in significant cost saving.

Abstract
PURPOSE This study was designed to investigate survival after curative resection of colorectal liver metastases in patients with expanded indications. METHODS A total of 501 patients had 545 liver resections for metastatic colorectal cancer. There were no predefined criteria for resectability with regard to the number or size of the tumors, locoregional invasion, or extrahepatic disease, except that resection had potential to be complete and macroscopically curative. All patients who had curative hepatic resection were advised to start postoperative adjuvant chemotherapy. RESULTS A total of 259 patients had expanded indications (52 percent), including 14 with liver metastases >10 cm, 194 with bilateral deposits, 140 with four or more liver metastases, and 73 with extrahepatic disease. The overall actuarial survival rates at one, three, five, and ten years were 88, 67, 45, and 36 percent, respectively, for patients with classic indications and 84, 53, 34, and 24 percent, respectively, for patients with expanded indications (P = 0.0009). In the group of expanded indications, there were more patients who received preoperative than postoperative chemotherapy: 72 (28 percent) vs. 18 (7 percent; P < 0.0001), and 148 (70 percent) vs. 131 (61 percent; P = 0.0466). In a multivariate analysis, four or more liver metastases and extrahepatic disease were independent predictors of poor outcome. Adjuvant chemotherapy significantly improved survival (P = 0.0002). CONCLUSIONS This study suggested that liver resection should be indicated in patients with expanded indications. The extent of the benefits of preoperative and postoperative chemotherapy needs to be quantitated.

Abstract
OBJECTIVES To highlight an infrequent occurrence using a series of clinical cases with symptoms and signs, and specific radiological findings allowing its diagnosis and treatment, which is in most cases successful. PATIENTS AND METHODS A descriptive and retrospective study of patients diagnosed by computed tomography scanning and then treated with surgery in the Pancreas and Biliary Unit of a University Hospital from March 1999 to September 2005. RESULTS There were 6 female patients with a mean age of 33.5 years (range 11-72). Most common signs included pain and a palpable mass in the abdomen. Three patients were diagnosed by computed tomography scanning, and a differential diagnosis with a neuroendocrine tumor was performed for the remaining three subjects. Surgical treatment was adapted to each patient according to the findings and images seen in their computed tomography scans. Biopsy results confirmed the presumed diagnoses, and showed one case of solid pseudopapillary carcinoma of the pancreas. Average hospital stay was of 18.16 days (range 8-30). Mortality rate was 0%. No recurrences occurred during follow-up for 46.3 months on average (range 12-76). CONCLUSIONS The presence of a huge mass in the pancreas of a young female should prompt suspicion for a solid pseudopapillary tumor. Given its low malignant potential, and the presence of specific radiographic patterns, its diagnosis should be accurate, as radical surgical treatment is effective.

Abstract
OBJECTIVE To determine perioperative factors related to postoperative renal dysfunction in patients receiving liver transplants who had normal renal function before surgery. PATIENTS AND METHODS We analyzed the cases of 189 consecutive patients. Patients with hepatorenal syndrome and previously diagnosed renal insufficiency were excluded, as were patients undergoing a second transplant operation. Postoperative renal dysfunction was diagnosed when creatinine levels exceeded 1.5 mg x dL(-1) in the first postoperative week. Multivariate analysis of preoperative variables (patient characteristics; Child-Pugh score; status with the United Network for Organ Sharing; and sodium, coagulation, hemoglobin, and creatinine levels); intraoperative variables (blood product units required, duration of surgery, reperfusion syndrome, surgical technique, and crystalloids required); and postoperative variables (hemodialysis or filtration, reoperation, mortality, creatinine levels at 6 and 12 months). RESULTS One hundred fifty patients with normal kidney function were included. Postoperative renal dysfunction developed in 45 (30%). Differences between patients with and without postoperative renal dysfunction were found for weight; sex; Child-Pugh score; blood transfusion requirements (mean [SD] of 2.36 [2.4] units of packed red cells in the group of patients with renal dysfunction vs 1.3 [1.8] in the patients with normal function); and reperfusion syndrome (26 [66.7%] patients with renal dysfunction and 35 [21.5%] without). The last 2 variables continued to be significantly correlated with renal dysfunction in the multivariate analysis with a relative risk of 1.25, (95% confidence interval [CI], 1.01-1.55) for units of blood transfusion and 2.41 (95% CI, 1.04-5.57) for reperfusion syndrome. Renal replacement therapy was used in 4 patients (2.7%). Mortality rates were similar. At 6 and 12 months, 26 (17.3%) and 18 (12%) patients had renal dysfunction. CONCLUSIONS Acute renal dysfunction is a frequent complication following a liver transplant and it is associated with transfusion of more units of blood products even when the average transfusion amount is not large.

Abstract
BACKGROUND The outcome of surgical treatment of hepatocellular carcinoma (HCC) could be improved by applying patient selection criteria based on tumoral aggressiveness. Here we analyzed the prognostic role of the expression of several genes involved in cell-cycle regulation in a group of patients with HCC. METHODS We retrospectively studied 93 patients (67 transplanted and 26 resections) treated between 1996 and 2000. In micro-thick sections from paraffin-embedded tumoral tissues, the expression of p53, pRb, p16, and cyclin D1 was analyzed. A logistic regression model was used to detect factors related to vascular invasion. A Cox regression model was applied to identify pathologic and molecular factors with the capacity to predict the recurrence of HCC. RESULTS Only tumor size>3 cm (odds ratio [OR]: 3.4; 95% CI: 1.2-9.9; P=0.019) and pRb expression (OR: 4.1; 95% CI: 1.02-17; P=0.053) were associated with an increased risk of vascular invasion. The regression model applied to the group of transplanted patients showed three factors that were independently related to recurrence: vascular invasion (OR 7.5; 95% CI: 1.1-51.8; P=0.039); pRb expression (OR: 11; 95% CI: 1.2-96.9; P=0.03); and p16 expression (OR: 69.7; 95% CI: 5.1-9448; P=0.001). In the group of resected patients, pRb expression was associated with higher risk of recurrence only in the univariate analysis (P=0.037). The multivariate analysis showed tumor size>3 cm (OR: 57.5; 95% CI: 1.1-51.8; P=0.039) and vascular invasion (OR: 6.1; 95% CI: 1.05-35.3; P=0.044) to be significantly associated with recurrence. CONCLUSIONS Of the molecular factors studied, only pRb expression was useful as a predictive factor of vascular invasion in patients with HCC, and also of recurrence in transplanted patients with this carcinoma. pRb expression may be relevant to consider when selecting patients for resection and when identifying transplanted patients with a high risk of recurrence.

Abstract
OBJECTIVE To evaluate the feasibility, safety, efficacy, amount of hemorrhage, postoperative complications, and ischemic injury of selective clamping in patients undergoing minor liver resections. SUMMARY BACKGROUND DATA Inflow occlusion can reduce blood loss during hepatectomy. However, Pringle maneuver produces ischemic injury to the remaining liver. Selective hemihepatic vascular occlusion technique can reduce the severity of visceral congestion and total liver ischemia. PATIENTS AND METHODS Eighty patients undergoing minor hepatic resection were randomly assigned to complete clamping (CC) or selective clamping (SC). Hemodynamic parameters, including portal pressure and the hepatic venous pressure gradient (HVPG), were evaluated. The amount of blood loss, measurements of liver enzymes alanine aminotransferase (ALT), aspartate aminotransferase (AST), and postoperative evolution were also recorded. RESULTS No differences were observed in the amount of hemorrhage (671 +/- 533 mL versus 735 +/- 397 mL; P = 0.54) or the patients that required transfusion (10% versus 15%; P = 0.55). There were no differences on postoperative morbidity between groups (38% versus 29%; P = 0.38). Cirrhotic patients with CC had significantly higher ALT (7.7 +/- 4.6 versus 4.5 +/- 2.7 mukat/L, P = 0.01) and AST (10.2 +/- 8.7 versus 4.9 +/- 2.1 mukat/L; P = 0.03) values on the first postoperative day than SC. The multivariate analysis demonstrated that high central venous pressure, HVPG >10 mm Hg, and intraoperative blood loss were independent factors related to morbidity. CONCLUSIONS Both techniques of clamping are equally effective and feasible for patients with normal liver and undergoing minor hepatectomies. However, in cirrhotic patients selective clamping induces less ischemic injury and should be recommended. Finally, even for minor hepatic resections, central venous pressure, HVPG, and intraoperative blood loss are factors related to morbidity and should be considered.
