RESUMO
Knowledge of ectopic insulinomas comes from single cases. We performed a systematic review through PubMed, Web of Science, Embase, eLibrary and ScienceDirect of all cases reported in the last four decades. We also describe one unreported patient. From 28 patients with ectopic insulinoma, 78.6% were female and mean age was 55.7 ± 19.2 years. Hypoglycaemia was the first symptom in 85.7% while 14.3% complained of abdominal pain or genital symptoms. Median tumour diameter was 27.5 [15-52.5] mm and it was localised by CT (73.1%), MRI (88.9%), [68Ga]Ga-DOTA-exedin-4 PET/CT (100%), 68Ga-labelled-DOTA-conjugated somatostatin analogue PET/TC (100%), somatostatin receptor scintigraphy (40%) and endoscopic ultrasound (50%). Ectopic insulinomas were located at duodenum (n = 3), jejunum (n = 2), and one respectively at stomach, liver, appendix, rectum, mesentery, ligament of Treitz, gastrosplenic ligament, hepatoduodenal ligament and splenic hilum. Seven insulinomas were affecting the female reproductive organs: ovary (n = 5), cervix (n = 2) and remaining tumours were at retroperitoneum (n = 3), kidney (n = 2), spleen (n = 1) and pelvis (n = 1). 89.3% underwent surgery (66.7% surgery vs. 33.3% laparoscopy) and 16% underwent an ineffective pancreatectomy. 85.7% had localized disease at diagnosis and 14.3% developed distant metastasis. Median follow-up time was 14.5 [4.5-35.5] months and mortality was reported in 28.6% with median time until death of 60 [5-144] months. In conclusion, ectopic insulinomas are presented as hypoglycaemia with female preponderance. Functional imaging [68Ga]Ga-DOTA-exedin-4 PET/CT and 68Ga-labelled-DOTA-conjugated somatostatin analogue PET/TC have very high sensitivity. Clinicians should be alert to the possibility of extra-pancreatic insulinomas when classic diagnostic tests and intraoperative pancreas exploration failed to locate the tumour.

INTRODUCTION: The main objective of this study was to analyse the results of the surgical treatment of ampullary neuroendocrine tumours (NET) based on transduodenal ampullectomy and pancreatoduodenectomy, in a reference centre in hepatobiliopancreatic pathology. METHOD: Retrospective, observational study, including all patients operated on for pancreatic and/or duodenal NET in a reference unit of hepatobiliopancreatic pathology and prospectively registered between January 1st, 1993 and September 30th, 2021. For those parameters not present, retrospective research was performed. Demographic, clinical, analytical and pathological data were analysed. A descriptive study was carried out. Overall and disease-free survival was calculated using Kaplan-Meier curves and the Log-Rank test. RESULTS: Of 181 patients operated on for pancreatic and/or duodenal NET, only 9 were located in the ampulla of Vater, which represents 4.9% of all pancreatic and/or duodenal NET. Pancreatoduodenectomy (PD) was performed in 6 patients, while 3 patients underwent transduodenal ampullectomy (TDA). Longer surgical time and more postoperative complications were observed in the PD group. There were no differences in hospital stay. Overall and disease-free survival at 5 years in the PD group compared to ATD was 83.3% vs. 100% and 50% vs. 100%, respectively. CONCLUSIONS: Ampullary NET without locoregional involvement or risk factors, can be treated by conservative surgeries such as transduodenal ampullectomy.

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.

INTRODUCTION: Intrahepatic cholangiocarcinoma is a primary liver neoplasm whose only curative treatment is surgery. The objective of this study was to determine the prognostic factors for survival of intrahepatic cholangiocarcinoma treated surgically with curative intent. METHODS: Sixty-seven patients who had been treated surgically for this neoplasm were collected at Bellvitge University Hospital between 1996 and 2017. Epidemiological, clinical, surgical, anatomopathological, morbidity, mortality and survival data have been analysed. RESULTS: Postoperative study reflects our centre's experience in the surgical treatment of intrahepatic cholangiocarcinoma over a period of 21 years. Lymphadenectomy was associated with increased morbidity, and vascular invasion in the pathological study was the most important risk factor in the survival analysis. CONCLUSIONS: This study reflects our centre's experience in the surgical treatment of intrahepatic cholangiocarcinoma over a period of 21 years. Lymphadenectomy was associated with increased morbidity, and vascular invasion in the pathological study was the most important risk factor in the survival analysis.

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.

INTRODUCTION: Chronic pain in chronic pancreatitis is difficult to manage. The objective of our study is to assess the control of pain that is refractory to medical treatment in patients with an inflammatory mass in the head of the pancreas, as well as to compare the two surgical techniques. METHODS: A retrospective study included patients treated surgically between 1989 and 2011 who had been refractory to medical treatment with inflammation of the head of the pancreas. An analysis of the short and long-term results was done to compare patients who had undergone pancreaticoduodenectomy (PD) and/or resection of the head of the pancreas with duodenal preservation (RHPDP). RESULTS: 22 PD and 12 RHPDP were performed. Postoperative complications were observed in 14% of patients, the most frequent being delayed gastric emptying (14.7%) and pancreatic fistula (11.7%). No statistically significant differences were found in terms of surgical technique. Pain control was satisfactory in 85% of patients, 43% presented de novo diabetes mellitus, and 88% returned to their work activities. Fourteen patients died during follow-up, 7 due to malignancies, and some were related to tobacco use and alcohol consumption. The overall 5 and 10 year survival rates were 88% and 75% respectively. CONCLUSION: Cephalic resection in patients with intractable pain in chronic pancreatitis is an effective therapy that provides good long-term results in terms of pain control, with no significant differences between the two surgical techniques. Patients with chronic pancreatitis have a high mortality rate associated with de novo malignancies.

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.

Several techniques have been proposed for liver transplantation with inadequate hepatic artery (HA) anastomosis. We aimed to analyze outcomes of arterial reconstruction with the splenic artery (SA). This was a prospective study of our experience with recipients who underwent arterial anastomosis on the SA compared with patients who underwent standard HA. We included 54 patients in the SA group and 1405 in the HA group. Patients in SA group were more frequently retransplantation (31% vs. 8%; P = 0.001), required more transfusion (11 ± 12 vs. 6 ± 9.9 PRC; P = 0.001), had longer surgeries (424 ± 95 vs. 394 ± 102 min; P = 0.03), and longer hospital stays (28 ± 29 vs. 20 ± 18 days; P = 0.002). There were no differences in vascular and biliary complications (15% and 7%; P = 0.18; and 32% and 23%; P = 0.32), primary dysfunction (11% and 9%; P = 0.74), reoperation (12% and 10%; P = 0.61), postoperative mortality (13% and 7%; P = 0.12) and 5 years survival (66% vs. 63%; P = 0.71). Following primary transplantation, there were no differences. The outcomes of arterial reconstruction using the recipients' SA in adult liver transplantation are comparable to those for standard HA reconstruction after a first transplant.

BACKGROUND: The aim of this study was to evaluate whether the placement of a coaxial double-pigtail plastic stent (DPS) within a lumen-apposing metal stent (LAMS) may improve the safety of endoscopic ultrasound (EUS)-guided drainage of pancreatic fluid collections (PFCs). METHODS: This was a retrospective cohort study including patients with PFCs and an indication for transmural drainage. Two strategies (LAMS alone or LAMS plus DPS) were used at the endoscopist's discretion. RESULTS: A total of 41 patients were treated (21 LAMS alone; 20 LAMS plus DPS). The characteristics of the PFCs, and the technical and clinical success rates did not differ between groups. The LAMS alone group had a significantly higher rate of adverse events than the LAMS plus DPS group (42.9â% vs. 10.0â%; Pâ=â0.04). Bleeding was the most frequent adverse event observed. CONCLUSIONS: The addition of a coaxial DPS to LAMS was associated with a lower rate of adverse events in EUS-guided drainage of PFCs.

INTRODUCTION: The need for fluoroscopy guidance in patients undergoing endoscopic ultrasound-guided transmural drainage (EUS-TMD) of peripancreatic fluid collections (PFCs) remains unclear. AIMS: The aim of this study was to compare general outcomes of EUS-TMD of PFCs under fluoroscopy (F) vs fluoroless (FL). METHODS: This is a comparative study with a retrospective analysis of a prospective and consecutive inclusion database at a tertiary centre, from 2009 to 2015. All patients were symptomatic pseudocyst (PSC) and walled-off pancreatic necrosis (WON). Two groups were assigned depending on availability of fluoroscopy. The groups were heterogeneous in terms of their demographic characteristics, PFCs and procedure. The main outcome measures included technical and clinical success, incidences, adverse events (AEs), and follow-up. RESULTS: Fifty EUS-TMD of PFCs from 86 EUS-guided drainages were included during the study period. Group F included 26 procedures, PSC 69.2%, WON 30.8%, metal stents 61.5% (46.1% lumen-apposing stent) and plastic stents 38.5%. Group FL included 24 procedures, PSC 37.5%, WON 62.5%, and metal stents 95.8% (lumen-apposing stents). Technical success was 100% in both groups, and clinical success was similar (F 88.5%, FL 87.5%). Technical incidences and intra-procedure AEs were only described in group F (7.6% and 11.5%, respectively) and none in group FL. Procedure time was less in group FL (8min, p=0.0341). CONCLUSIONS: Fluoroless in the EUS-TMD of PFCs does not involve more technical incidences or intra-procedure AEs. Technical and clinical success was similar in the two groups.

INTRODUCTION: Pancreaticoduodenectomy (PD) is usually contraindicated in chronic liver disease. The objective of the present study was to analyze PD results in cirrhotic patients, and compare them with non-cirrhotic ones. METHODS: Between 1994 and 2014 we prospectively collected all patients with a PD for periampullar neoplasms in Hospital Universitari de Bellvitge. We registered preoperative, intraoperative and postoperative variables. We defined patients undergoing PD with liver cirrhosis as the study group (CH group), and those without liver cirrhosis as the control group (NCH group). A case/control study was performed (1/2). RESULTS: We registered 15 patients in the CH group, all with good liver function (Child A), and included 30 patients in NCH group. The causes of hepatopathy were HCV (60%) and alcoholism (40%). For the 3 moments studied, the CH group had a lower blood platelet count and a higher prothrombin ratio, compared with NCH group. Postoperative morbidity was 60% and mean postoperative stay was 25±19 days, with no differences in terms of complications between CH group and NCG group (73% vs. 53%, P=.1). Presence of ascites was higher in the CH group compared with NCH group (28 vs. 0%, P<.001). There were no differences in terms of hemorrhage or pancreatic fístula. Four patients of the CH group and 2 patients of the NCH group were reoperated on (26.7 vs. 6.7%, P=.1). There was no postoperative mortality. CONCLUSIONS: PD is a safe procedure in cirrhotic patients with good liver function although it presents high morbidity.

There is conflicting evidence favoring both the use of human serum (HS) and of human serum albumin (HSA) in human islet culture. We evaluated the effects of HS versus HSA supplementation on 1) in vitro ß-cell viability and function and 2) in vivo islet graft revascularization, islet viability, ß-cell death, and metabolic outcome after transplantation. Islets isolated from 14 cadaveric organ donors were cultured for 3 days in CMRL 1066 medium supplemented with HS or HSA. After 3 days in culture, ß-cell apoptosis was lower in HS group (1.41 ± 0.27 vs. 2.38 ± 0.39%, p = 0.029), and the recovery of islets was 77 ± 11% and 54 ± 1% in HS- and HSA-cultured groups, respectively. Glucose-stimulated insulin secretion (GSIS) was higher in HS group (29.4, range 10.4-99.9, vs. 22.3, range 8.7-70.6, p = 0.031). In vivo viability and revascularization was determined in HS- and HSA-cultured islets transplanted into the anterior chamber of the eye of Balb/c mice (n = 14), and ß-cell apoptosis in paraffin-embedded mouse eyes. Islet viability and ß-cell apoptosis were similar in both groups. Revascularization was observed in one graft (HS group) on day 10 after transplantation. Islet function was determined in streptozotocin (STZ)-diabetic nude mice (n = 33) transplanted with 2,000 IEQs cultured with HS or HSA that showed similar blood glucose levels and percentage of normoglycemic animals over time. In conclusion, human islets cultured in medium supplemented with HS showed higher survival in vitro, as well as islet viability and function. The higher in vitro survival increased the number of islets available for transplantation. However, the beneficial effect on viability and function did not translate into an improved metabolic evolution when a similar number of HSA- and HS-cultured islets was transplanted.

BACKGROUND: Endoscopic management of walled-off pancreatic necrosis (WOPN) is an area of great interest with many still unanswered questions, including the role of mechanical necrosectomy versus irrigation. The aim of this study was to evaluate a new method of endoscopic transmural necrosectomy. METHODS: Patients with WOPN after necrotizing pancreatitis, who underwent endoscopic transmural necrosectomy using a lumen-apposing metal stent with vigorous irrigation sessions, were prospectively recruited between September 2011 and August 2014. Initial endoscopic session was performed by EUS-guided drainage and lavage sessions by flushing saline through the stent. Technical and clinical success rates, number of repeat interventions, and adverse events were analyzed. RESULTS: Twelve patients with 13 WOPN collections (median size 12.4 ± 2.94 cm) underwent endoscopic treatment. Clinical success was achieved in 100 % of cases after a median of three sessions per patient (range 2-8). The median length of hospitalization was 15.9 days. Median procedure time of the access session was 31 ± 10.16 min. No adverse events (AE) were described during the procedures or 24 h after. There were four AE (two infections and two bleedings) between sessions, but only two were severe (16.6 %). There was no need for surgery, and no mortalities occurred. Mean time to stent retrieval was 9 ± 3.4 weeks. Mean follow-up was 13 months with only one recurrence at 12 months after stent removal. CONCLUSIONS: This new variant of irrigation endoscopic transmural necrosectomy without mechanical debridement helps to simplify the technique, is feasible, and has excellent outcomes in WOPN treatment.

BACKGROUND AND AIMS: When ERCP fails, EUS-guided interventional techniques may be an alternative. The aim of this study was to evaluate the general outcomes and safety of EUS-guided methylene blue cholangiopancreatography in patients with failed ERCP in benign biliopancreatic diseases. METHODS: Patients with benign biliopancreatic diseases and failed ERCP were included. EUS-guided cholangiopancreatography plus injection of methylene blue was performed, and then ERCP using coloring agent flow as an indicator of papilla orifice was performed. Procedures were prospectively collected in this observational, single-center study. Technical success, clinical success, and adverse events were analyzed retrospectively. RESULTS: Eleven patients were included (10 choledocholithiasis, 1 pancreatic stricture). The main reason for failed ERCP was an unidentifiable papilla. EUS-guided ductal access with cholangiopancreatography and papilla orifice identification was obtained in all cases. Technical success and clinical success rates of 91% were achieved, with successful biliopancreatic drainage in 10 patients. Adverse events included 1 peripancreatic abscess attributed to a precut, which was successfully treated. No adverse events were related to the first EUS-guided stage. CONCLUSION: EUS-guided cholangiopancreatography with methylene blue injection seems to be a feasible and helpful technique for treatment in patients with benign biliopancreatic diseases with previous failed ERCP because of an undetectable papilla.

UNLABELLED: Organ shortage has forced transplant teams to progressively expand the acceptance of marginal donors. METHODS: We performed a comparative analysis of the post-transplant evolution depending on donor age (group I: less than 70 years old (n=474) vs. group II: 70 or more years old [n=105]) over a 10 year period (2002-2011). RESULTS: Donors over 70 years old were similar to donors less than 70 years old in terms of ICU stay, gender, weight, laboratory results, and use of vasoactive drugs. However, the younger donor group presented with cardiac arrest more often (GI: 14 vs. GII: 3%, P=.005). There were no differences in initial poor function (GI: 6% vs. GII: 7,7%; P=.71), ICU stay (GI: 2.7±2 vs. GII: 3.3±3.8, P=.46), hospital stay (GI: 13.5±10 vs. GII: 15.5±11, P=.1), or hospital mortality (GI: 5.3 vs. GII: 5.8%, P=.66) between receptors of more or less than 70 year old grafts. After a median follow up of 32 months, no differences were found in the incidence of biliary tract complications (GI: 17 vs. GII: 20%, P=.4) or vascular complications (GI: 11 vs. GII: 9%, P=.69). The actuarial 5 year survival was similar for both study groups (GI: 70 vs. GII: 76%, P=.54). CONCLUSIONS: In our experience, the use of grafts from donors older than 70 years, when other risk factors are avoided (cold ischemia, steatosis, sodium levels), does not worsen the results of liver transplantation on the short or long term.

Venous outflow is critical to the success of liver transplantation (LT). In domino liver transplantation (DLT), the venous cuffs should be shared between the donor and the recipient, and the length can be compromised. The aim of this study was to describe and compare the technical options for outflow reconstruction used at our institution. This was a retrospective analysis of 39 consecutive DLT recipients between January 1997 and May 2013. Twenty-seven men and 12 women (mean age, 61.8 ± 4.3 years) underwent LT and consented to receive a liver from a donor with familial amyloid polyneuropathy (FAP). The main indications were hepatocellular carcinoma and hepatitis C virus cirrhosis. All recipients underwent transplantation by a piggyback technique. Liver procurement in the FAP donors was performed with the classic technique in 22 patients and with the piggyback technique in the last 17. In these latter cases, for vascular outflow reconstruction, a cadaveric venous graft was interposed between the hepatic vein (HV) stump of the FAP liver and the recipient HV in 11 cases (28%). Since 2011, we have employed arterial grafts to be interposed between the vessels stumps: a tailored arterial graft in 5 patients and an aortic graft in 1 case. There was no postoperative mortality. Arterial and portal complications presented in 2 (5.1) and 4 patients (10.3), respectively. Postoperative outflow complications (post-LT subacute Budd-Chiari syndrome) occurred in 4 patients, and all of them had received a venous interposed graft for reconstruction. The incidence of outflow complications tended to be higher among patients with venous grafts than those with arterial graft interposition. Overall patient survival at 1, 3, 5, and 10 years was 97%, 79%, respectively. Arterial grafts constitute a feasible and safe option for vascular outflow reconstruction in DLT because they are associated with a relatively low incidence of complications. The recently proposed Bellvitge arterial graft technique should be added to the current range of available surgical modalities.

INTRODUCTION: Surgery is the accepted treatment for infected acute pancreatitis, although mortality remains high. As an alternative, a staged management has been proposed to improve results. Initial percutaneous drainage could allow surgery to be postponed, and improve postoperative results. Few centres in Spain have published their results of surgery for acute pancreatitis. OBJECTIVE: To review the results obtained after surgical treatment of acute pancreatitis during a period of 12 years, focusing on postoperative mortality. MATERIAL AND METHODS: We have reviewed the experience in the surgical treatment of severe acute pancreatitis (SAP) at Bellvitge University Hospital from 1999 to 2011. To analyse the results, 2 periods were considered, before and after 2005. A descriptive and analytical study of risk factors for postoperative mortality was performed RESULTS: A total of 143 patients were operated on for SAP, and necrosectomy or debridement of pancreatic and/or peripancreatic necrosis was performed, or exploratory laparotomy in cases of massive intestinal ischemia. Postoperative mortality was 25%. Risk factors were advanced age (over 65 years), the presence of organ failure, sterility of the intraoperative simple, and early surgery (< 7 days). The only risk factor for mortality in the multivariant analysis was the time from the start of symptoms to surgery of<7 days; furthermore, 50% of these patients presented infection in one of the intraoperative cultures. CONCLUSIONS: Pancreatic infection can appear at any moment in the evolution of the disease, even in early stages. Surgery for SAP has a high mortality rate, and its delay is a factor to be considered in order to improve results.

OBJECTIVE: To analyse the indications and results of pancreatic metastasis resection in a university hospital. PATIENTS AND METHODS: An analysis was performed on a prospective database from 1990 to 2010. The clinical-pathological and perioperative details, as well the follow-up results were analysed. RESULTS: Of the 710 pancreatic resections performed, 7 cases (0.99%) were due to a metastasis in the pancreas. The mean age of the patients was 53.3 years (20-77 years), and 5 were male and 2 were women. Five (70%) patients were asymptomatic. The origin of the metastasis was: colon (n=3), kidney (n=2), jejunum (n=1), and testicle (n=1). In 4 cases they were situated in the head, 2 in the tail, and one in the body. The metastases were metachronous in 4 (57%) patients and the disease free interval was 29 months (17-48). There were 3 cases (43%) of synchronous metastases, with a mean recurrence-free time of 14 months, and survival of 21.6 months. This was lower than that of patients with metachronous metastases, which was 27.8 months and with a survival of 32 months, respectively. The overall disease free interval and survival was 21.85 months and 27.5 months, respectively. CONCLUSION: Resection of pancreatic metastases can extend survival in selected patients.
