RESUMEN
BACKGROUND: Survival rates after surgery and adjuvant chemotherapy for pancreatic ductal adenocarcinoma (PDA) remain low. Selected patients with portal/superior mesenteric vein (PV) involvement undergo PV resection at pancreaticoduodenectomy (PD). This study analyses outcomes for PD with/without PV resection in patients with PDA. METHODS: A retrospective analysis of prospectively collected data on patients requiring PD for histologically proven adenocarcinoma between 1/1997 and 9/2009 identified 326 patients with PDA, with 51 requiring PD with PV resection. Patients were analyzed in two groups: PD + PV resection vs. PD alone. Multivariate analysis was used to identify predictive variables influencing survival and the Kaplan-Meier method to estimate patient survival. RESULTS: Mean age for patients with PV resection was 66.4 (range 46-80) years, 47% were male. Both groups had similar patient demographics, perioperative and tumor characteristics. Postoperative morbidity was similar for patients with and without PV resection (27.5 vs. 28.4%). 30-day mortality was significantly higher in patients with PV resection (13.7%) vs. PD alone (5.1%). Overall survival however was similar in both groups (median PD alone 14.8 months vs. 14.5 months PD + PV). Multivariate analysis identified age, tumor grading, stay on the ICU and lack of chemotherapy as independent risk factors for reduced long-term survival. CONCLUSION: In carefully selected patients, PV resection results in similar long-term survival compared to PD alone. In selected patients, PV infiltration may be considered a sign of anatomical proximity of the tumor, rather than only a sign of increased tumor aggressiveness.

INTRODUCTION: Surgical sphincteroplasty (SS) for sphincter of Oddi dysfunction (SOD) can be performed primarily or following failed endoscopic therapy. The role of SS in an era of endoscopic management is unclear. This study presents long-term follow-up of patients who had undergone SS at a tertiary referral unit. METHODS: Patients were identified from a departmental database and sent post-operative questionnaires to review pain scores and satisfaction with the procedure. Indications, pre-operative interventions and complications were recorded. RESULTS: Seventeen patients underwent SS over 13 years. Thirteen patients had objective features of biliary obstruction (delayed excretion of isotope or elevated sphincter pressures). The positive predictive value, sensitivity and specificity of morphine 99mTc-TBIDA in this series was 100, 100 and 92%, respectively. There were 12 responders of whom all but one had symptomatic improvement. Median follow-up was 5.1 years. Pain was significantly lower following SS (16 ± 9 vs. 67 ± 11; p = 0.003) and median satisfaction with the procedure was high (95%). CONCLUSIONS: Excellent symptomatic pain relief following SS can be achieved in carefully selected patients. Manometry does not appear to be essential for diagnosing SOD and morphine provocation hepatic scintigraphy was used to reliably identify patients who would benefit from SS.

BACKGROUND: Right posterior sectoral bile duct (RPSD) anomalies seen in up to 8% of the population rarely are injured at laparoscopic cholecystectomy. Paucity of data on the management of these injuries led the authors to conduct this study aimed at reviewing management strategies for laparoscopic RPSD injuries at a specialist center. METHODS: Of 221 patients, 15 (6.7%; 4 men; mean age, 51 years; range, 21-75 years) treated between 1992 and 2009 for injuries to the RPSD were followed up for a median of 58 months (range, 7-208 months). Case notes, imaging, and follow-up data were reviewed. RESULTS: The RPSD injury was immediately recognized in 3 (20%) of the 15 patients, whereas in the remaining patients, biliary injury was suspected on day 1 (range, 1-18 days) due to bile leak/biloma. The diagnosis of RPSD injury was made by a combination of investigations including endoscopic retrograde cholangiopancreatography (ERCP) (n = 11), drain tube cholangiogram (n = 10), on-table cholangiogram (n = 3), and nuclear scan (n = 3). An intact common bile duct and absence of RPSD were identified on cholangiography (ERCP and on-table cholangiogram), whereas drain tube cholangiogram demonstrated a leaking RPSD in all cases. The majority of the patients (8/15, 53%) were managed nonoperatively with combined percutaneous drainage and endoscopic stenting, whereas six patients (40%) were managed with biliary reconstruction (immediate: n = 2; delayed 14-87 days: n = 4). Clinical and radiologic confirmation of complete cessation of bile leak was demonstrated 56 days (range, 7-62 days) after injury. The long-term outcome included a dilated right duct system with transient elevation of liver function tests in two patients (1 each in the nonoperative and surgical management groups), whereas the remaining patients all remain well at this writing. CONCLUSION: Bile leak in the presence of an intact common duct shown on cholangiogram should raise the suspicion of an RPSD injury. Expertise is needed to interpret the absence of RPSD in these cases. Drain tube cholangiogram is an important adjunctive investigation. In selected cases, the results of nonoperative management alone is comparable with the results of reconstruction.

AIM: The aim of this retrospective study was to analyse the outcome following hepatic resection for metastatic STS and to identify factors predicting survival. METHODS: All patients who underwent hepatic resection for metastatic STS between August 1997 and April 2009 were included. The data was obtained from a prospectively maintained database. Patients' demographics, clinico-pathological parameters, overall survival and the factors predicting survival were analysed. RESULTS: Thirty-six patients underwent hepatic resection for metastasis, with a median age of 58 years. The predominant site of primary tumour was the gastro-intestinal tract (50%). Leiomyosarcoma was the most common histological type (54%). The median interval between the primary and metastatic resections was 17 months. Thirteen patients had synchronous tumours. 24 patients had major liver resections and 10 patients had bi-lobar disease. The median number of liver lesions resected was 1(1-6) and the median maximum diameter was 11 cm (1-26 cm). R0 resection was performed in 31 patients. The 1-, 3- and 5-year overall survival from the time of metastasectomy was 90.3%, 48.0% and 31.8% respectively, with a median survival of 24 months. Factors associated with poor survival on univariate analysis were the presence of high grade tumours (p = 0.04), primary leiomyosarcoma (p = 0.01) and positive resection margin of liver metastasis (p = 0.04), whilst multivariate analysis predicted primary leiomyosarcoma as a risk factor for poor survival (p = 0.01). CONCLUSION: Hepatic resection for metastatic STS appears to be valuable in carefully selected patients with acceptable long-term survival. The aim of surgery must be an R0 resection to offer a chance of cure.

BACKGROUND: Bile duct injuries after laparoscopic cholecystectomy often cause long-term morbidity, with a number of patients resorting to litigation. The present study aimed to analyze risk factors for litigation and to quantify the subsequent medicolegal burden. METHODS: A total of 67/106 patients (26 male) with major laparoscopic cholecystectomy bile duct injuries (LCBDI) and a minimum 2-year follow-up, replied to a questionnaire covering patient perception toward the complication, physical/psychological recovery, and subsequent litigation. These data were collated with prospectively collected data related to the LCBDI and subsequent management, and a multivariate regression model was designed to identify potential risk factors associated with litigation. RESULTS: Most patients felt they had been inadequately informed prior to surgery [47/67 (70%)] and after the LCBDI [50/67 (75%)], and a majority remained psychologically traumatized at the time of evaluation [50/67 (75%)]. Of these, 22 patients had started litigation by means of a "letter of demand" (LOD; n = 10) or prosecution (n = 12). Nineteen (19/22%) cases have been closed in favor of the plaintiff. There was no difference between the awards for LOD versus prosecution cases, and average compensation was £40,800 versus £89,875, respectively (p = n.s). On multivariate analysis, age < 52 years (p = 0.03), associated vascular injury (p = 0.014), immediate nonspecialist repair (p = 0.009), and perceived incomplete recovery following LCBDI (p = 0.017) were identified as independent predictors for possible litigation. CONCLUSIONS: On the basis of the present study, nearly one third of patients with major transectional LCBDI are likely to resort to litigation. Younger patients and those in whom repair is attempted prior to specialist referral are likely to initiate litigation.

BACKGROUND: The shortage of donor livers has led to increased utilization of steatotic marginal livers. Bioelectrical impedance analysis (BIA) uses the principles of electric current flows through tissue, with less resistance offered if the water content is high and the opposite in the presence of fat. Our hypothesis was that liver steatosis would result in an increased resistance to current flow, and correlate with the degree of liver steatosis. METHODS: Before studying cadaveric donor livers for transplantation, this study was performed in patients undergoing liver resection. A total of 37 patients undergoing liver resection for cancer were analysed with BIA, using a handheld, specially calibrated Maltron BIA analyser (BioScan 915) with modified tertrapolar electrodes. These electrodes were applied to the liver surface and resistance was recorded. To validate the results of BIA, a liver biopsy was performed. Histopathology was graded quantitatively as no steatosis, mild, moderate, or severe steatosis according the percentage of fat as well as qualitatively by type of fat (micro and macrovesicular). RESULTS: Bioelectric resistance showed a correlation with macroveiscular steatosis (P = .03). CONCLUSION: BIA is a simple, noninvasive technique and its use should be explored in donor livers to assess steatosis.

Gangliocytic paragangliomas are rare tumors located in the gastrointestinal tract that are considered to be benign. They are composed of spindle-shaped cells, epithelioid cells, and ganglion-like cells. They usually present with abdominal pain, and/or gastrointestinal bleeding, and occasionally with obstructive jaundice. We report a case of obstruction in a 17-year-old female, which on histology was found to be a gangliocytic paraganglioma, with an extremely unusual presentation. Intraoperatively, the patient was found to have local tumor extension and regional lymph node invasion, and so she underwent a pylorus-preserving pancreaticoduodenectomy, with local lymph node clearance. We discuss the management of this unusual case and review the literature.

INTRODUCTION: Carcinoma of the ampulla of Vater is said to carry a significantly better prognosis than pancreatic ductal adenocarcinomas arising in the pancreatic head. However, it is uncertain as to whether this is due to the fact that they have differing oncological characteristics or simply an earlier presentation as a result of the exophytic morphology of ampullary lesions causing obstruction of the bile ducts. METHODS: All patients undergoing pancreaticoduodenectomy between January 1998 and December 2004 were identified from a prospectively maintained database. Patients with a pathologically confirmed ampullary (AMP) tumour were compared to those with a carcinoma of the head of the pancreas (HOP). Tumour characteristics including size, stage and degree of differentiation were analysed as were survival data. RESULTS: 71 AMP and 144 HOP tumours were resected during the period studied and had full histology reports available for assessment. The median diameter of the AMP tumours was significantly less than those of the HOP (2 cm vs. 3 cm; p = 0.04). The T stage distribution differed significantly between the AMP and HOP tumours in favour of the former (Stages I--10 vs. 0 (p = 0.03); II--29 vs. 13 (p = 0.04); III--25 vs. 121 (p = 0.01); IV--7 vs. 10). The number of resection specimens with positive lymph nodes was lower in the AMP group (31 vs. 121; p = 0.03) as was the prevalence of vascular invasion (33 vs. 114; p = 0.006) and neural invasion (23 vs. 134; p = 0.009). There was no difference in the degree of differentiation of the AMP and HOP tumours. The 5-year survival rates were significantly better in the AMP group at 60% vs. 20% (p = 0.008). Subdivision of AMP carcinoma into polypoid (60%) and ulcerating (40%) lesions revealed a non-significant survival advantage in favour of polypoid tumours at (64% vs. 60%; p = 0.07) at 5 years. CONCLUSIONS: The outcome of resection for AMP is significantly better than for pancreatic ductal adenocarcinomas arising in the periampullary region. Although the anatomical position of AMP tumours may contribute to this survival advantage, the HOP tumours exhibit more adverse histological features suggesting that they are different diseases and hence the difference in survival.

BACKGROUND: Needle biopsy of a suspicious liver lesion could guide management in the setting of equivocal imaging and serology, although it is not recommended generally because there is the possibility of tumour dissemination outside the liver. The incidence of needle track seeding following biopsy of a suspicious liver lesion is ill-defined, however. METHODS: A systematic review and meta-analysis of observational studies published before March 2007 was performed. Studies that reported on needle tract seeding following biopsy of suspicious liver lesions were identified. Lesions suspected of being hepatocelleular cancer (HCC) were considered. Data on the type of needle biopsy, diagnosis, incidence of needle track seeding duration to seeding, follow-up and impact on outcome were tabulated. RESULTS: Eight studies identified by systematic review on biopsy of HCC were included in a meta-analysis. The pooled estimate of a patient with seeding per 100 patients with HCC was 0.027 (95% confidence interval (CI) 0.018 to 0.040). There was no difference whether a fixed or random effects model was used. Q was 4.802 with 7 degrees of freedom, p = 0.684; thus the observed heterogeneity was compatible with variation by chance alone. The pooled estimate of a patient with seeding per 100 patients per year was 0.009 (95% CI 0.006 to 0.013), p = 0.686. CONCLUSIONS: In this systematic review we have shown that the incidence of needle tract tumour seeding following biopsy of a HCC is 2.7% overall, or 0.9% per year.

AIM: To report the prevalence and outcome of cholangiocarcinoma arising in primary sclerosing cholangitis for a British tertiary referral centre. METHODS: All patients diagnosed with primary sclerosing cholangitis and concurrent cholangiocarcinoma were identified from a prospectively maintained departmental database, and the mode of presentation, management and outcome were determined. RESULTS: Of 370 patients with primary sclerosing cholangitis, 48 patients (13%) were diagnosed with a cholangiocarcinoma within a median time of 0.51 months (range: 0-73.12) from presentation to the unit. Mode of presentation included: inoperable tumours (n = 14); incidental findings in transplant hepatectomy specimens (n = 13); primary sclerosing cholangitis follow-up (n = 9); transplant work-up (n = 5); transplant waiting list (n = 5); suspected tumour confirmed at transplant (n = 1), and incidental finding at cholecystectomy (n = 1). The diagnosis was confirmed by: radiology-guided biopsy (n = 27); MRI (n = 3); CT (n = 2); laparoscopy or laparotomy (n = 2), and frozen section at transplant (n = 1). Management consisted of: transplantation (n = 14, including 1 abandoned); hepatic resection (n = 8), and palliation through stenting (n = 26). The overall median survival of the cohort was 4.9 months (range: 0.09-104.5). Median survival ranged from 2.6 months (range: 0.09-35.3) for palliation to 7.6 months (range: 0.6-99.6) for transplantation and 52.8 months (range: 3.7-104.5) for resection. There was no difference in survival between the transplant and resection groups (p = 0.14). CONCLUSIONS: Cholangiocarcinoma is a common finding in primary sclerosing cholangitis and regular screening of this cohort of patients at referring centres is advocated to detect early tumours, as surgical treatment at an early stage offers significantly better outcomes for this cohort of patients.

INTRODUCTION: The objective of this study was to determine the outcome of on table repair of iatrogenic bile duct injuries (IBDIs) following laparoscopic cholecystectomy, by specialist hepatobiliary surgeons as an outreach service. PATIENTS AND METHODS: Prospectively collected data on IBDI managed as an outreach service, was analysed retrospectively. The Strasberg classification was used to define types of injury. RESULTS: There were 22 patients. Twenty (91%) had type E 'classical' excision injuries, two had types B and D. Two type E cases had co-existent vascular injury both with right hepatic artery injuries; one also had a co-existent portal vein injury. A Roux-en-Y hepaticojejunostomy was used to repair the IBDI in 21 (95%) patients. One type D injury had duct repair over a T-tube. No attempt was made to reconstruct the injured hepatic arteries, while the portal vein injury was primarily repaired. The median follow-up was 210 days (range, 47-1088 days). Two patients developed bile leak and cholangitis while another developed transient jaundice. There were no postoperative mortalities. All patients were followed up at our centre. CONCLUSIONS: Repair of IBDI as an outreach service by specialist surgeons is feasible and safe, with minimal disruption to the patient pathway. Prompt recognition and definitive management may help reduce complaints and medicolegal litigation.

AIM: To compare the effects of preoperative chemotherapy on liver parenchyma morphology, as well as morbidity and mortality after liver resection for colorectal liver metastases. METHODS: Prospectively collected data on 173 patients undergoing liver resection for CLM between 1/2003 and 9/2005 was analysed in three groups: A: preoperative oxaliplatin (Ox, n=70); B: other chemotherapeutic agents (OC, n=60); and C: surgery alone without chemotherapy (SA, n=43). Blood transfusion, hospital stay, operative procedure, peak postoperative bilirubin levels, complications and histopathology of the resected liver were compared. RESULTS: Intra-operative blood transfusion requirement (34%) and biliary complications (16%) was higher in patients receiving oxaliplatin-based chemotherapy (p=0.01 and p=0.06, respectively). Oxaliplatin-based chemotherapy was also associated with sinusoidal dilatation of mild grade in 52.8% vs. 26.6% and 23.3% patients (p=0.007 and p=0.004) in other groups, respectively. Steatosis was similarly distributed across the study group. Postoperative mortality was 2, 1 and 4 patients, respectively (p=ns). CONCLUSION: Oxaliplatin-based preoperative chemotherapy is associated with vascular alterations in the liver parenchyma without significantly increasing the risk of steatosis, or postoperative morbidity and mortality.

AIMS: To report seven cases of epithelioid haemangioendothelioma (EHE) of the liver, a rare, low-grade malignant neoplasm of vascular origin that have been treated in our institution. MATERIALS AND METHODS: Patients with ages ranging from 25 to 60 years presenting mainly with non-specific symptoms, such as right upper quadrant abdominal pain or weight loss. The tumours presented as multiple, nodular lesions involving both lobes of the liver. This type of tumour is often difficult to diagnose, with the final diagnosis being established only by histological examination. The key to diagnosis was the demonstration of cells containing factor VIII-related antigen. RESULTS: Five patients underwent orthotopic liver transplantation (OLT), four of whom are alive at a median follow up 38 months (11-88 months). One patient died of recurrent of disease at 88 months. Two patients did not receive an OLT since they presented with extrahepatic metastatic disease; they died at 21 and 25 months from diagnosis. CONCLUSION: Orthotopic liver transplantation may be considered as a potentially curative treatment for this rare form of tumour when the disease is confined to the liver.

INTRODUCTION: Management of pancreatic leak and haemorrhage is complex with high mortality rates. In this study, the results of completion pancreatectomy which was performed as a last resort option were analysed. PATIENTS AND METHODS: 25 patients who had completion pancreatectomy from among 677 patients who had pancreatoduodenectomy or distal pancreatectomy over a period of 18 years were analysed in terms of the indications for completion pancreatectomy, outcome and survival data. RESULTS: Indications for completion pancreatectomy include pancreatic leak in 12 patients (48%), both bleeding and pancreatic leak in 8 (32%), and haemorrhage alone in 5 (20%) patients. 18 (72%) patients also had splenectomy. Median ITU stay was 4 and 8 days for those who survived and died post-completion pancreatectomy, respectively. 36% patients had septicaemia and 32% patients had multiple organ failure. 12 patients survived the operation with a median survival of 52 months. CONCLUSION: 25 (3.6%) patients required surgical intervention for pancreatic complications. The incidence of splenectomy was 84.6% in those who died after completion pancreatectomy compared to 58.3% of those who survived (Fisher's exact test two-sided 0.20). Despite significant morbidity and mortality, completion pancreatectomy has a role in the management of post-pancreatic surgical complications.

AIM: To document the prevalence and to evaluate the management strategies of haemorrhagic complications following pancreaticoduodenectomy (PD). METHODS: All patients who underwent PD from 1/2000 to 10/2005 and experienced at least one episode of haemorrhage during the 30 first days postoperatively were recorded. Etiology of haemorrhage, treatment strategy and mortality rate were recorded and analyzed. RESULTS: A total of 362 patients underwent PD during this period and 32 (8.8%) had haemorrhage postoperatively of whom 15 died (47% mortality rate). Primary intraluminal haemorrhage was recorded in 13 patients, primary intra-abdominal haemorrhage in 5 patients and secondary haemorrhage in 14 patients. Successful management of haemorrhage with angioembilization occurred in 2 patients in the study group. Statistical analysis revealed sepsis and sentinel bleed as risk factors for post-PD haemorrhage and pancreatic leak and sentinel bleed as risk factors for secondary haemorrhage (p < 0.05). CONCLUSIONS: Haemorrhage after PD is a life-threatening complication. Sepsis, pancreatic leak, and sentinel bleed are statistical significant factors predicting post-PD haemorrhage. Sentinel bleed is not statistically significant associated with postoperative mortality, but with the onset of secondary haemorrhage. The effectiveness of therapeutic angioembolization was not demonstrated in our study.

BACKGROUND: Diabetes after total pancreatectomy is commonly described as 'brittle' with most series reporting outcomes after resection for pancreatitis alone. The aim of this study was to determine glycaemic control in patients resected for benign and malignant disease. METHODS: A retrospective analysis of all patients undergoing total pancreatectomy (1989-2003) from a single institution was done. Data of diabetic control were obtained from case notes, general practitioners and telephonic consultation. Comparison was made against a matched type 1 diabetic population. RESULTS: Forty-seven patients with a median age of 59 years (range 17-85 years) and median follow-up of 50 months (range 5-136 months) were identified. Thirty-five underwent primary resection with 11 receiving completion procedures. Thirty were for malignancy (19 deceased) and 17 for benign/indeterminate histology (2 deceased). Thirty-three patients were available for detailed follow-up. There was no significant difference between median HbA(1c) of the study group and the control (8.2% versus 8.1%). The majority of patients reported diabetic control and daily performance as excellent or good. Resection for pancreatitis gave poorer subjective control (p < 0.05) than those resected for malignancy. Two patients required in-patient treatment for diabetic complications, with no deaths related to diabetes observed. CONCLUSION: Diabetes after total pancreatectomy is not necessarily associated with poor glycaemic control and in the majority results in equivalent biochemical control compared to a normal type 1 diabetic population.

OBJECTIVES: The object of our study was to report on the experience with vascular resections at pancreatectomy in two European specialist hepatopancreatobiliary centres and evaluate outcome and prognostic factors. PATIENTS AND METHODS: From 1989 to 2002, 45 patients (21 men, 24 women) underwent pancreatectomy for a pancreatic mass: Whipple's procedure (n=33), total pancreatectomy (n=10) or left splenopancreatectomy (n=2), along with a vascular resection, i.e. venous (n=39), arterial (n=1) or venous + arterial (n=5). RESULTS: Operative mortality was nil, postoperative mortality was 2.2% (n=1); 34 patients had an uneventful postoperative course. Reoperations were performed for portal vein thrombosis (n=1), pancreatic leak (n=1), gastric outlet syndrome (n=1) and gastrointestinal bleeding (n=1). In all, 43 patients had cancer on pathology examination, with retropancreatic invasion in 72% and lymph node extension in 62.8%. Resection was R0 in 21 cases. Vessel wall invasion was present in 13 cases and 19 had perivascular invasion. Disease-free survival (DFS) at 1, 2 and 3 years was 36.0%, 15.0% and 12.0%, respectively. Median DFS length was 8.7 months (95% CI: 7.2; 10.2). Overall survival rates were 56.6%, 28.9% and 19.2%, respectively. Median survival length was 14.2 months (95% CI: 9.8; 18.6). A multivariate analysis of prognostic variables identified tumour location (other than head of pancreas), neoadjuvant chemotherapy and advanced disease stage as adverse factors for DFS. CONCLUSION: Survival and DFS rates of these patients are comparable to those without vascular resection. Tumour localization, tumour stage, neoadjuvant treatment and tumour recurrence are explanatory variables of survival. Tumour localization, tumour stage and neoadjuvant treatment were explanatory variables for DFS. However, the type and extent of vascular resections as well as vessel wall invasion does not affect survival and DFS.
