Abstract
BACKGROUND AND AIMS The pre-operative determination of resectability of pancreatic and peri-ampullary neoplasia assists the selection of patients for surgical or non-surgical treatment. This study investigated whether the addition of laparoscopy with laparoscopic ultrasound to dual-phase helical CT could improve the accuracy of assessment of resectability. PATIENTS AND METHODS Prospective study of 305 patients referred to a single unit for consideration of pancreatic resection who underwent dual-phase helical CT scanning +/- laparoscopy with laparoscopic ultrasound. Data were collected on patient demographics, CT findings, assessment of operability, laparoscopic assessment (LA), surgical procedures and histology. RESULTS LA was undertaken in 239/305 patients, 190 of whom were considered CT resectable, and 49 CT unresectable. Of the 190 CT resectable patients, LA correctly identified unresectability in 28 (15%: metastases in 15; vascular encasement in 6; anaesthesia for laparoscopy found 7 unfit for major resection) and incorrectly in 2 (vascular encasement), but did not identify unresectability in 33; LA correctly confirmed resectability in the remainder (prediction improved, chi(2) = 9.73, p < 0.01). Of the 49 CT unresectable patients, LA correctly identified resectability in 4, and incorrectly in 12, and correctly identified unresectability in the remaining 33. Sixty-six of the 305 patients did not undergo LA, of whom 23 underwent resection. CONCLUSION When added to dual-phase helical CT, laparoscopy with laparoscopic ultrasound provides valuable information that significantly improves the selection of patients for surgical or non-surgical treatment.

Abstract
INTRODUCTION Knowledge of microbiology in the prognosis of patients with necrotizing pancreatitis is incomplete. AIM This study compared outcomes based on primary and secondary infection after surgery for pancreatic necrosis. METHOD From a limited prospective database of pancreatic necrosectomy, a retrospective case note review was performed (October 1996 to April 2003). RESULTS 55 of 73 patients had infected pancreatic necrosis at the first necrosectomy. 25 of 47 patients had resistant bacteria to prophylactic antibiotics (n = 21) or did not receive prophylactic antibiotics (n = 4), but this was not associated with a higher mortality (9 of 25) compared to those with sensitive organisms (4 of 22). Patients with fungal infection (n = 6) had a higher initial median (95% CI) APACHE II score compared to those without (11 (9-13) verus 8.5 (7-10), p = 0.027). Five of six patients with fungal infection died compared to 13 of 47 who did not (p = 0.014). With the inclusion of secondary infections 21 (32%) of 66 patients had fungal infection with 10 (48%) deaths compared to 11 (24%) of 45 patients without fungal infection (p = 0.047). CONCLUSION Whether associated with primary or secondary infected pancreatic necrosis, fungal but not bacterial infection was associated with a high mortality.

Abstract
BACKGROUND The outcome of pancreatic resection for chronic pancreatitis in patients with preoperative opioid use is not well described. METHODS During 1997 to 2003, 112 of 231 patients referred with chronic pancreatitis underwent pancreatic resection. The outcome of patients who had preoperative opioid use (N=46) was compared with those without (N=66). RESULTS Patients who used opioids presented at a younger age and had a younger age of symptom onset, longer symptom duration, more hospitalizations, a higher frequency of diabetes mellitus, a higher pain score, and more restriction in daily activity (all P<.05). Twenty-one (46%) patients with opioid use had a total pancreatectomy compared with 9 (14%) without opioid use (P=.0002); the 21 patients also had a higher frequency of postoperative bleeding and early reoperation (8 vs 2, P<.02; 11 vs 3, P=.003, respectively). Mortality and overall morbidity was not significantly different between the 2 groups (4 vs 1, 27 vs 34, respectively). Pain scores improved postoperatively in both groups (P=.001) and was not significantly different between the groups from 12 months onward (median follow-up of 12 months, range, 3-60 months). Twenty percent of patients who used preoperative opioids however reverted to morphine use compared with 6% of patients who had not used opioids. CONCLUSIONS Patients who used opioids had more advanced disease than patients without opioid use, accounting for part of the postoperative morbidity. Although long-term pain relief was comparable between the 2 groups, maintaining opioid withdrawal was more problematic in those with preoperative opioid use. Earlier referral for resection may be warranted in this group of patients.

Abstract
Pancreatic hamartoma is a rare benign lesion and may be mistaken for a malignancy, as demonstrated by two cases. The first case was a 29-year-old man who presented with a 7-month history of intermittent upper abdominal pain, nausea and vomiting and a 15-kg weight loss. CT and MRI revealed a mass in the head of the pancreas. The second case was a 62-year-old man who presented with a 2-year history of intermittent abdominal pain, vomiting and a 25-kg weight loss. Although positron emission tomography was normal, CT revealed thickening of the duodenal wall and endoluminal ultrasonography revealed a tumour in the head of the pancreas. Both patients recovered from uneventful Kausch-Whipple pancreatoduodenectomy (in the first patient, it was pylorus-preserving), and in each case the histological diagnosis was hamartoma. Pancreatic hamartoma can present with vague, non-specific symptoms which, despite modern diagnostic tools, can be difficult to diagnose. Surgical resection with histopathological examination is required to confirm the diagnosis.

Abstract
BACKGROUND Pancreatic fistula remains a significant problem in pancreatic disease, trauma and surgery. Whilst improved diagnostic and treatment techniques, including endoscopic approaches, have resulted in considerably improved outcomes, surgical intervention remains an important aspect of treatment but has been relatively poorly documented. AIMS The aims were to review the recent world literature on the relative incidence of pancreatic fistula and the results of surgical treatment. RESULTS The pancreatic fistula rate following partial pancreato-duodenectomy was 421 (12.9%) in 3,268 patients in 13 large series; 80 (13.0%) in 671 patients after left pancreatectomy in 6 large series, and 28 (11.9%) in 243 patients after pancreatic trauma in 4 recent series. The success rate of surgical procedures for external pancreatic fistulae was 101 (90.2%) in 112 patients with an overall mortality of 7 (6.3%) reported in 9 series. For internal pancreatic fistulae the success rate of surgical treatment was 61 (92%) in 66 patients with an overall mortality of 6 (9%) reported in 7 series. CONCLUSIONS The treatment of established pancreatic fistula remains challenging. Although surgical treatment is reserved for patients who have failed all other treatments, the success rate is 90-92% but with a mortality of 6-9%.

Abstract
BACKGROUND Pancreatoblastoma is a rare tumour mainly presenting in childhood but also in adults. OBJECTIVES The aim was to determine the clinical course of pancreatoblastoma by an analysis of reported cases. METHODS Patients with pancreatoblastoma were identified from Medline and combined with patients identified from the Royal Liverpool University Hospital. RESULTS There were 153 patients with a median (range) age at presentation of 5 (0-68) years and a male:female ratio of 1.14:1. The most frequent site was the head of pancreas (48/123, 39%). The median and 5-year (95% CI) survival rates were 48 months and 50% (37-62%) respectively. At presentation there were 17 (17%) out of 101 patients with metastases, the liver being the commonest site (15/17, 88%). On univariate analysis, factors associated with a worse prognosis were synchronous (p = 0.05) or metachronous metastases (p < 0.001), non-resectable disease at presentation (p < 0.001) and age > 16 years at time of presentation (p = 0.02). On multivariate analysis, resection (p = 0.006) and metastases post-resection (p = 0.001) but not local recurrence influenced survival. CONCLUSIONS Pancreatoblastoma is one of the pancreatic tumours with a relatively good prognosis. The treatment of choice is complete resection with long-term follow-up aiming to treat any early local recurrence or metastasis.

Abstract
The two main types of hereditary pancreatic neuroendocrine tumours are found in multiple endocrine neoplasia type 1 (MEN-1) and von Hippel-Lindau disease (VHL), but also in the rarer disorders of neurofibromatosis type 1 and tuberous sclerosis. This review considers the major advances that have been made in genetic diagnosis, tumour localization, medical and surgical treatment and palliation with systemic chemotherapy and radionuclides. With the exception of the insulinoma syndrome, all of the various hormone excess syndromes of MEN-1 can be treated medically. The role of surgery however remains controversial ranging from no intervention (except enucleation for insulinoma), intervening for tumours diagnosed only by biochemical criteria, intervening in those tumours only detected radiologically (1-2 cm in diameter) or intervening only if the tumour diameter is > 3 cm in diameter. The extent of surgery is also controversial, although radical lymphadenectomy is generally recommended. Pancreatic tumours associated with VHL are usually non-functioning and tumours of at least 2 cm in diameter should be resected. Practice guidelines recommend that screening in patients with MEN-1 should commence at the age of 5 years for insulinoma and at the age of 20 years for other pancreatic neuroendocrine tumours and variously at 10-20 years of age for pancreatic tumours in patients with VHL. The evidence is increasing that the life span of patients may be significantly improved with surgical intervention, mandating the widespread use of tumour surveillance and multidisciplinary team management.

Abstract
Abstract
Background
The aim was to evaluate the outcome of major resection for chronic pancreatitis in patients with and without vascular involvement.
Methods
Of 250 patients with severe chronic pancreatitis referred between 1996 and 2003, 112 underwent pancreatic resection. The outcome of 17 patients (15·2 per cent) who had major vascular involvement was compared with that of patients without vascular involvement.
Results
The 95 patients without vascular involvement had resections comprising Beger's operation (39 patients), Kausch–Whipple pancreatoduodenectomy (28), total pancreatectomy (25) and left pancreatectomy (three). Twenty-five major vessels were involved in the remaining 17 patients. One or more major veins were occluded and/or compressed producing generalized or segmental portal hypertension, and three patients also had major arterial involvement. Surgery in these patients comprised Beger's operation (eight), total pancreatectomy (five), Kausch–Whipple pancreatoduodenectomy (two) and left pancreatectomy (two). Perioperative mortality rates were significantly different between the groups (two of 95 versus three of 17 respectively; P = 0·024). There were similar and significant improvements in long-term outcomes in both groups.
Conclusion
Resection for severe chronic pancreatitis in patients with vascular complications is hazardous and is associated with an increased mortality rate. Vascular assessment should be included in the routine follow-up of patients with chronic pancreatitis, to enable early identification of those likely to develop vascular involvement and prompt surgical intervention.

Abstract
BACKGROUND Non-alcoholic duct destructive chronic pancreatitis is a rare entity with specific pathological features. The majority of the patients are from Japan. We report a case with involvement of the distal bile duct, the gallbladder, the duodenum and the ampulla, and present a review of patients from Europe and the USA since 1997. CASE PRESENTATION A 56-year-old man presented with a 3-month history of mild acute pancreatitis and obstructive jaundice, followed by increasing weight loss, lethargy and epigastric pain. CT showed a mass in the head of the pancreas. ERCP demonstrated a smooth stricture of the intra-pancreatic main bile duct and an irregular, incomplete, stricture in the main pancreatic duct. A pancreatic cancer could not be reliably excluded, and, therefore, he underwent a pylorus-preserving Kausch-Whipple's pancreatoduodenectomy. RESULTS Histopathology showed typical peri-ductal T cell-rich lymphoplasmacellular and eosinophilic infiltration of the pancreas, with involvement of the distal bile duct but, also, unusual inflammatory infiltration of the gallbladder, the duodenum and the ampulla. CONCLUSION The inflammatory process in non-alcoholic duct-destructive chronic pancreatitis can affect the entire pancreato-biliary region and mimics pancreatic cancer. Currently, there are no definitive criteria for pre-operative diagnosis, so it is very difficult for one to avoid resection.

Abstract
BACKGROUND Reports of synchronous or metachronous double kidney-pancreas cancers are very rare. METHODS We present 2 patients with renal cell carcinoma and synchronous (1 patient) or metachronous (1 patient) primary pancreatic ductal adenocarcinoma. The patients underwent resection for both cancer types with a worthwhile outcome. RESULTS The appearance of different primaries in an individual may indicate a genetic predisposition to different neoplasms. The study of double primary cancers is important because it might provide understanding of a shared genetic basis of different solid tumors. CONCLUSIONS The association between these two cancers demands more detailed epidemiological and molecular investigation. From a clinical viewpoint a resectional policy is recommended.

Abstract
BACKGROUND The aim of this study was to identify factors associated with death after surgery in patients with extensive pancreatic necrosis. METHODS Sixty-four patients who underwent pancreatic necrosectomy between 1996 and 2002 were studied. RESULTS The median age was 60.5 (95 per cent confidence interval (c.i.) 57 to 64) years and 40 patients (62.5 per cent) were tertiary referrals. The initial median Acute Physiology And Chronic Health Evaluation (APACHE) II score was 9 (95 per cent c.i. 7.9 to 10.1) and there were 21 deaths (32.8 per cent). Twenty-eight patients (43.8 per cent) underwent minimally invasive retroperitoneal pancreatic necrosectomy (MIRP) and the remainder had open pancreatic necrosectomy (OPN); 44 (72.1 per cent) of 61 patients had infected pancreatic necrosis at the time of the first procedure. Seven patients who underwent MIRP died compared with 14 after OPN (P = 0.240). Patients who died were older than those who survived, with higher APACHE II scores at presentation, and before and after surgery (P = 0.001). Survivors had significantly longer times to surgery than those who died (P = 0.038). All 21 patients who died required intensive care compared with 26 of 43 survivors (P < 0.001). Thirty of 36 patients who had the OPN procedure required intensive care compared with only 17 of 28 patients who had MIRP (P = 0.042). Logistic regression analysis showed that only postoperative APACHE II score was an independent predictor of increased mortality (P = 0.031). CONCLUSION Advanced age and increasing APACHE II score, and a need for postoperative intensive care, were the most important predictors of outcome after pancreatic necrosectomy.

Abstract
INTRODUCTION Open surgery for pancreatic necrosis is associated with considerable morbidity and mortality. We report the results of a recently developed minimally invasive technique that we adopted in 1998. METHODS A descriptive explanation of the approach is given together with the results of a retrospective analysis of patients who underwent a minimally invasive retroperitoneal pancreatic necrosectomy (MIRP) between August 1998 and April 2002. PATIENTS There were 24 patients with a median (range) age of 61 (29-75) years. The initial median (range) APACHE II score was 8 (2-21). All patients had infected pancreatic necrosis with at least 50% pancreatic necrosis. In three patients it was not possible to complete the first MIRP because of technical reasons. RESULTS A total of 88 procedures were performed with a median (range) of 4 (0-8) per patient. Twenty-one (88%) patients developed 36 complications during the course of their illness. Five patients required an additional open procedure: 2 for subsequent distant collections, 2 for bleeding and 1 for persisting sepsis and a distant abscess. Six (25%) patients who had MIRP died. The median (range) post-operative hospital stay was 51 (5-200) days. CONCLUSIONS MIRP is a new technique that has shown promising results, and could be preferable to open pancreatic necrosectomy in selected patients. However, unresolved issues remain to be overcome and the exact role of MIRP in the management of pancreatic necrosis has yet to be defined.

Abstract
Pancreatic cancer is a common, highly lethal disease that is rising in incidence. Chemotherapy based on 5-fluorouracil (5-FU) has been shown to prolong survival in advanced pancreatic cancer. Gemcitabine improves major symptoms and survival outcomes compared with bolus 5-FU. Many novel small molecules are being widely and actively researched. These compounds are based on classical mechanisms of action as well as biological therapies targeting novel cellular survival pathways, and include fluoropyrimidines, nucleoside cytidine analogues, platinum analogues, topoisomerase-inhibitors, antimicrotubule agents, proteasome inhibitors, vitamin D analogues, arachidonic acid pathway inhibitors, histone deacytylator inhibitors, farnesyltransferase inhibitors and epidermal growth factor receptor therapies. Adjuvant chemotherapy has also demonstrated the best survival outcomes following resection compared to other adjuvant or neo-adjuvant strategies such as radiation-based treatments. These benefits are superimposed on the dramatic increase in resectability rates and reduction in post-operative mortality achieved by centralisation of treatment in high-volume speciality centres. Newer 'small-molecule' drugs as well as the latest 'large-molecule' biological agents hold considerable promise for the future. Real advances are anticipated over the next five years but are dependent on large randomised controlled trials for success.

Abstract
Many clinicians prefer to avoid surgery in patients with carcinoid neoplasia, because of its slow growth and relatively favourable prognosis. Nevertheless, the commonest cause of death in patients with carcinoid is advanced metastatic disease, and both clinical and epidemiological data indicate that the more effectively the disease is ablated, the more long-lasting the benefit. Multidisciplinary management of patients with carcinoid must consider inherited risk, possible multiple carcinoids and/or synchronous non-carcinoid cancer, and the use of a range of investigations that also evaluate the 10% of patients with carcinoid syndrome with or without valvular heart disease. Although primary size is correlated with the presence of nodal with or without liver metastases, carcinoid tumours <1 cm in diameter may be metastatic at presentation, particularly those arising within the small intestine. In the jejunum and ileum, resection of all sizes of carcinoid with local and regional nodes is preferred, to prevent nodal dissemination causing mesenteric ischaemia with or without infarction. Resection of nodal metastases should be undertaken in those with persistent or recurrent nodal disease if possible. Appendiceal and right colonic carcinoids are most effectively treated by right hemicolectomy with local and regional nodal clearance, as for adenocarcinoma. However, for most appendiceal carcinoids which are <1 cm in diameter and non-invasive, appendicectomy alone is sufficient. For appendiceal carcinoids 1-2 cm in diameter, histopathological assessment helps to determine the need for hemicolectomy. Liver resection has been followed by prolonged 5 year survival in several series and is recommended in appropriate patients to attempt cure or to debulk metastatic disease. Liver transplantation has had only qualified success in highly selected patients without extra-hepatic disease in whom other therapies have failed.

Abstract
Abstract
Background
Total pancreatectomy may be warranted in patients with advanced chronic pancreatitis in whom partial resection has failed and in those with end-stage pancreatic function. A new operation, duodenum- and spleen-preserving total pancreatectomy, is described.
Methods
Nineteen consecutive patients with chronic pancreatitis who had duodenum- and spleen-preserving total pancreatectomy were studied.
Results
There were 15 men and four women with a median age of 40 (range 29–64) years. The aetiology was alcohol misuse in nine, hereditary pancreatitis in five and idiopathic in five patients. All patients had chronic intractable abdominal pain. Six had undergone pancreatic surgery previously and one had had multiple coeliac plexus blocks. There were ten postoperative complications in five patients, and one hospital death. The median hospital stay was 25 (range 10–84) days. There was a reduction in pain (P < 0·001) and analgesic use (P < 0·001) after surgery, and weight gain was noted at 12 and 24 months (P < 0·001). Nine patients required readmission to hospital, four because of surgical complications: adhesional obstruction in one, biliary stricture in two and duodenal obstruction in one. In the other five patients (four of whom had long-standing pre-existing diabetes mellitus) readmission was for better control of pain (three patients), diabetes mellitus (two), and diabetes-associated diarrhoea (two) or gastropathy (one).
Conclusion
Duodenum- and spleen-preserving total pancreatectomy has a role in selected patients with medically intractable pain from chronic pancreatitis.

Abstract
BACKGROUND Severe acute pancreatitis leads to a systemic inflammatory response characterized by widespread leucocyte activation and, as a consequence, distant lung injury. In CC chemokines the first two cysteine residues are adjacent to each other. The aim of this study was to evaluate the effect of Met-RANTES, a CC chemokine receptor antagonist, on pancreatic inflammation and lung injury in caerulein-induced acute pancreatitis in mice. METHODS Acute pancreatitis was induced in mice by hourly intraperitoneal injection of caerulein. Met-RANTES was administered either 30 min before or 1 h after starting caerulein injections, and pancreatic inflammation and lung injury were assessed. There were five groups of eight mice each including controls. RESULTS Treatment with Met-RANTES had little effect on caerulein-induced pancreatic damage. Met-RANTES, however, reduced lung injury when given either before administration of caerulein (mean(s.e.m.) lung myeloperoxidase (MPO) 1.47(0.19) versus 3.70(0.86)-fold increase over control, P = 0.024; mean(s.e.m.) microvascular permeability 1.15(0.05) versus 3.57(0.63) lavage to plasma fluorescein isothiocyanate-labelled albumin fluorescence ratio (L/P) per cent, P = 0.002) or after caerulein administration (lung MPO 1.96(0.27) versus 3.65(0.63)-fold increase over control, P = 0.029; microvascular permeability 0.94(0.04) versus 2.85(0.34) L/P per cent, P < 0.001). CONCLUSION Treatment with Met-RANTES reduces lung damage associated with caerulein-induced pancreatitis in mice. Chemokine receptor antagonists may be of use for the treatment of the systemic complications of acute pancreatitis.

Abstract
The results from pancreatic ductal adenocarcinoma appear to be improving with increased resection rates and reduced postoperative mortality reported by specialist pancreatic cancer teams. Developments with medical oncological treatments have been difficult, however, due to the fundamentally aggressive biological nature of pancreatic cancer and its resistance to chemotherapy coupled with a relative dearth of randomised controlled trials. The European Study Group for Pancreatic Cancer (ESPAC)-1 trial recruited nearly 600 patients and is the largest trial in pancreatic cancer. The results demonstrated that the current best adjuvant treatment is chemotherapy using bolus 5-fluorouracil with folinic acid. The median survival of patients randomly assigned to chemoradiotherapy was 15.5 months and is comparable with many other studies, but the median survival in the chemotherapy arm was 19.7 months and is as good or superior to multimodality treatments including intra-operative radiotherapy, adjuvant chemoradiotherapy and neo-adjuvant therapies. The use of adjuvant 5-fluorouracil with folinic acid may be supplanted by gemcitabine but requires confirmation by ongoing clinical trials, notably ESPAC-3, which plans to recruit 990 patients from Europe, Canada and Australasia. Major trials such as ESPAC-1 and ESPAC-3 have set new standards for the development of adjuvant treatment and it is now clear that such treatment in this field has the potential to significantly improve both patient survival and quality of life after curative resection.

Abstract
Recent advances have been made in the treatment of pancreas cancer. Specialized pancreas centres have reported an increasing rate of resections with reduced postoperative mortality. On account of the highly aggressive nature of pancreas cancer, there is a great challenge in identifying effective therapy concepts for advanced stages of the cancer as well as for the development of resection-associated measures. As large-scale, randomised, controlled studies are lacking, the additive therapy concepts after resection do not have a sufficiently scientific basis. The ESPAC-1 study, which included 600 patients, surpassed all previous studies on adjuvant therapy for pancreas cancer. This study has shown,for example, that the most promising adjuvant chemotherapy with 5-fluorouracil and folic acid leads to an equal if not better result than the multimodal regimen. This regimen can be superseded with the use of Gemcitabine, which will be evaluated in the ESPAC-3 study that includes 990 patients from various European countries including Germany, as well as from Canada and Australia. Participation in the large, phase-3 study therefore plays a key role in the continued development of the management of pancreas cancer.

Abstract
Abstract
Background
The accuracy of laparoscopic ultrasonography in staging pancreatic and periampullary tumours in a referral unit was determined and its use for the subgroup of tumours of stage T3 or greater was assessed.
Methods
From a larger series of staging laparoscopies 22 patients with pancreatic lesions and five with periampullary tumours who were being considered for resection were staged with laparoscopy and laparoscopic ultrasonography. Only patients with computed tomography (CT) or magnetic resonance imaging (MRI) scans indicating potentially or equivocally resectable disease were included. The laparoscopist was blinded to the results of CT and MRI. Laparoscopy and laparoscopic ultrasonography were undertaken according to a standard protocol using a B & K Medical Diagnostic Ultrasound System 3535 with a colour flow Doppler module. Ascitic fluid was sent for cytology and metastatic disease was biopsied. Results were recorded on a pro forma which included an assessment of resectability. In the case of large tumours this included an assessment of the potential for a positive resection margin or the need for portal vein resection to obtain tumour clearance. The decision to pursue resection was made by the consultant surgeon, based on all the information available including that from laparoscopic ultrasonography. No patient was denied a surgical exploration on the basis of local irresectability determined only by laparoscopic ultrasonography. The predictions regarding resectability were compared with findings at open surgery and with histology.
Results
Assessment of irresectability by laparoscopic ultrasonography resulted in nine true positives, 16 true negatives, no false positives and one false negative. For pancreatic adenocarcinoma there were eight true positives, 13 true negatives and one false negative. Among the pancreatic group ten of 13 tumours correctly predicted as resectable were stage T3 or greater (Union Internacional Contra la Cancrum, 1997). Of those predicted to be irresectable, all eight were T3 or greater. Among this latter group three were predicted to be irresectable on the basis of local factors alone, two on the basis of metastatic disease alone and three on the basis of both local factors and metastases. Overall, for detection of irresectable disease laparoscopic ultrasonography had a positive predictive value of 100 per cent, a negative predictive value of 94 per cent and an accuracy of 96 per cent. Accuracy was 95 per cent for both the pancreatic tumour subgroup and the T3 pancreatic subgroup.
Conclusion
Laparoscopic ultrasonography was accurate for predicting irresectability in this group of referred patients. The technique was also accurate for the subgroup with T3 or greater pancreatic tumours.

Abstract
Abstract
Background
The aim of the study was to quantify the risk of surgical intervention in families with hereditary pancreatitis referred to the European Registry of Hereditary Pancreatitis and Familial Pancreatic Cancer (EUROPAC).
Methods
Recruitment to EUROPAC started in 1997; families were considered if two or more members had chronic pancreatitis of unknown aetiology. Families were tested for protease serine 1 (PRSS1) mutations using polymerase chain reaction restriction digestion, sequencing the PRSS1 gene-screened negative families. Clinical information about surgical intervention was obtained from family members and referring clinicians, and the cumulative incidence of surgical intervention in the N291 and R122H mutation groups was determined with the Kaplan–Meier method.
Results
Forty-four families had the R122H mutation, 21 the N291 mutation, and 31 were negative for both. Some 14 (35 per cent) of 40 patients (median age 26·5 (95 per cent confidence interval (c.i.) 21·5–36·3) years) with the N291 mutation had an operative procedure for complications of pancreatitis, compared with 21 (25 per cent) of 83 patients (median age 24 (95 per cent c.i. 13·8–35·8) years) with the R122H variant. This resulted in a cumulative lifetime risk for surgical intervention of 0·6 (95 per cent c.i. 0·5–0·8) for the R122H mutation and 0·6 (0·5–0·8) for the N291 mutation (P = 0·11, log rank test).
Conclusion
Hereditary pancreatitis carries a significantly increased risk of surgical intervention in this cohort of patients, which equates to an estimated lifetime risk of around 60 per cent. The risk of surgery appears to be independent of PRSS1 mutation type.

Abstract
Abstract
Background
The aim of the study was to evaluate the initial results with a new technique of minimally invasive pancreatic necrosectomy (MIPN).
Methods
A retrospective audit was carried out of pancreatic necrosectomies performed on one unit from October 1996. Patients were divided into two groups: those admitted before November 1998 who underwent a conventional open necrosectomy and those admitted after this date who were considered for treatment with MIPN.
Results
Thirty-one patients underwent pancreatic necrosectomy, of which 20 cases were tertiary referrals. Thirteen patients (median age 51 (range 33–77) years; ten men, three women) admitted before November 1998 underwent a conventional open technique; seven of these patients died. Since then, 18 patients (median age 59 (range 33–74) years; ten women, eight men) have undergone necrosectomy, 12 by MIPN (median of 3 (range 1–6) procedures) and six by an open technique. Reasons for using an open technique included a left renal adenocarcinoma (one patient), poor access route (three patients) and failure to insert a guidewire under computed tomographic control (two patients). There were two deaths during this later period (P < 0·05, Fisher's exact test in comparison with the earlier time period). In patients who were discharged there was no difference in length of stay in the intensive treatment unit (median 5 (range 0–24) versus 5 (range 0–84) days) or in-hospital stay (median 66 (range 29–159) versus 75 (range 31–202) days) between the two time periods.
Conclusion
A minimally invasive approach provides a promising alternative to open pancreatic necrosectomy.

Abstract
Abstract
Background
Pancreatic cancer affects 8–12 per 100 000 population per year in Europe. Following resection, the long-term survival rate is only 10–15 per cent and the role of adjuvant treatment is uncertain. The aims of the study were to answer two questions: (1) whether there is a role for chemoradiation (40 Gy and 5-fluorouracil (5-FU), and (2) whether there is a role for chemotherapy (5-FU–folinic acid (FA)) weekly).
Methods
A multicentre European prospective randomized controlled trial was organized by the European Study Group for Pancreatic Cancer (ESPAC). A 2 × 2 factorial design was used, asking both questions of the same patient, and a pragmatic design asking only one of the two questions of each patient. The data were reviewed at regular intervals by the Independent Data and Safety Monitoring Committee (IDSMC).
Results
Some 531 patients with pancreatic ductal adenocarcinoma were randomized from 80 clinicians in 11 countries. Randomization was stratified by resection margin involvement; 82 per cent of patients were negative. Some 239 patients (45 per cent) are alive to date, at a median follow-up of 9 (interquartile range 1–24) months. Preliminary results show no evidence of a benefit for chemoradiation treatment (median survival 14 months with chemoradiation versus 15·7 months without; P = 0·24). There is some evidence of a survival benefit for patients having chemotherapy (median survival 19·5 months versus 13·5 months with no chemotherapy; P = 0·003). The effect is reduced when taking into account whether patients received radiotherapy (P = 0·01), indicating that radiotherapy may reduce the overall benefit of the chemotherapy. The IDSMC recommended closing recruitment to the chemoradiotherapy arm.
Conclusion
There is no role for adjuvant chemoradiotherapy in pancreatic cancer, but there may be a role for chemotherapy. ESPAC-3 is now randomizing between (1) surgery alone, (2) 5FU–FA and (3) gemcitabine.
