A comparative study of risk factors for pancreatic fistula after pancreatoduodenectomy or distal pancreatectomy.

BACKGROUND: Evidence associates various biometric and histological variables such as steatosis and absence of fibrosis as risk factors for post-operative pancreatic fistula (POPF) after pancreatoduodenectomy (PD). Following distal pancreatectomy (DP), the association between these factors and POPF is less clear. This study of patients, drawn from the same background population, undergoing PD or DP at a single centre is a comparative study of the risk factors for POPF after these two operations. METHODS: Associations between POPF and patient characteristics, pre-operative blood tests, data from pre-operative computed tomography (CT) imaging, assessment of histological steatosis and fibrosis were explored. RESULTS: 26/107 (24%) and 26/90 (29%) patients developed POPF after PD and DP respectively. Absence of fibrosis was associated with POPF (p < 0.001) after PD and its presence correlated with pancreatic duct width (p < 0.001). Steatosis was not associated with POPF (p = 0.910). Multivariable analysis showed pancreatic duct width (p = 0.016) and fibrosis (p = 0.025) to be independent predictors of POPF after PD. The only variable associated with POPF after DP was underlying pathology (p = 0.005). CONCLUSION: Pancreatic duct width is the most important variable related to POPF after PD and is correlated with fibrosis. Steatosis was not related to POPF. In contrast, after DP POPF appears to be related to the underlying disease.

Vasculobiliary complications following adult right lobe split liver transplantation from the perspective of reconstruction techniques.

Split liver transplantation (SLT) compensates for the organ shortage and provides an alternative solution for recipients disadvantaged by a smaller body size. Variations in the hepatic arterial anatomy and reconstructive techniques may lead to more technical complications, and we sought to analyze the incidence and risk factors of vasculobiliary complications with respect to reconstructive techniques. We identified 171 adult right lobe SLT procedures and 1412 whole liver transplantation (WLT) procedures between January 2000 and June 2012 and compared the results of these 2 groups. In the SLT group, arterial reconstruction techniques were classified into 4 subgroups (I-IV), and biliary reconstruction was classified into 2 groups [duct-to-duct (DD) anastomosis and Roux-en-Y hepaticojejunostomy (RH)]. Specific surgical complications were analyzed against reconstruction techniques. The overall incidence of vascular and biliary complications in the SLT group was greater than that in the WLT group (P = 0.009 and P = 0.001, respectively). There was no difference in hepatic artery thrombosis (HAT), but we saw a tendency toward early HAT in the presence of multiple hepatic arteries supplying the right lobe graft (group IV; 20%) in comparison with the other arterial reconstruction groups (P = 0.052). No difference was noticed in the overall incidence of biliary complications in either DD or RH recipients across 4 arterial reconstruction groups. When the arterial reconstruction involved a right hepatic artery (groups II and III) combined with a DD biliary anastomosis, there was a significant preponderance of biliary complications (P = 0.04 and P = 0.01, respectively). There was no survival difference between SLT and WLT grafts. In conclusion, the complications of SLT are directly related to arterial and biliary reconstruction techniques, and this classification helps to identify high-risk reconstructive techniques.

Etiology and management of hepatic artery thrombosis after adult liver transplantation.

Hepatic artery thrombosis (HAT) represents a major cause of graft loss and mortality after liver transplantation. It occurs in up to 9% of adult recipients. The early diagnosis of HAT decreases septic complications, multiorgan failure, and graft loss, and there are better outcomes after treatment. In this study, we reviewed 102 episodes of HAT, which were classified as early hepatic artery thrombosis (E-HAT) when they were diagnosed within the first 21 days after transplantation. The overall incidence of HAT was 7%: 31 episodes (30.4%) were identified as E-HAT, and 71 episodes (69.6%) were identified as late hepatic artery thrombosis (L-HAT). Graft dysfunction was the commonest presentation (30 cases or 29%). Most E-HAT cases were managed with retransplantation (74%), whereas early revascularization was carried out for only 13% with a 75% success rate. The incidence of retransplantation for L-HAT was only 41%, whereas 32% were too ill for relisting and eventually died. Successful conservative management was noted for 13 of the 102 patients (13%) with collateralization and good hepatic perfusion, with biliary complications encountered in 7 cases (54%) subsequently. A multivariate analysis showed that previous episodes of HAT, the number of arterial anastomoses, and a low donor weight were independent risk factors for E-HAT, whereas a history of upper abdominal operations (non-HAT), a previous history of HAT, a low donor weight, and a recipient age < 50 years were independent risk factors for L-HAT. The graft survival rates for HAT patients were 52%, 36.6%, and 27.4% at 1, 3, and 5 years, whereas the corresponding rates were 81.4%, 81.2%, and 76.4% for non-HAT patients. In conclusion, prompt revascularization for E-HAT patients decreases the incidence of serious, irreversible septic complications and graft loss and improves overall outcomes. A significant number of L-HAT patients do not require further intervention despite the high incidence of ischemic cholangiopathy.

Increasing the donor pool: consideration of prehospital cardiac arrest in controlled donation after circulatory death for liver transplantation.

Donor warm ischemia has implications for outcomes after liver transplantation (LT) using organs from donation after circulatory death (DCD) donors. Prehospital cardiac arrest (PHCA) before donation may generate a further ischemic insult. The aim of this single-center study of 108 consecutive DCD LT procedures was to compare the outcomes of PHCA and non-PHCA cohorts. A review of a prospectively collected database of all DCD grafts transplanted between January 2007 and October 2011 was undertaken to identify donors who had sustained PHCA. The unit policy was to consider such donors when transaminase levels were ≤4 times the normal range and had an improving trend. Twenty-six of the 108 DCD transplants were from DCD donors with PHCA, and 82 were in the non-PHCA cohort. A comparative analysis of the PHCA and non-PHCA cohorts showed better short-term results (a low incidence of acute kidney injury) for the PHCA group but satisfactory long-term results for both groups with no significant differences in graft or patient survival between them. In conclusion, a careful donor selection policy for including PHCA DCD donors with normalized liver function tests or transaminase levels ≤ 4 times the norm resulted in successful transplantation and could boost the donor pool with no adverse outcomes.

Live liver donation, ethics and practitioners: 'I am between the two and if I do not feel comfortable about this situation, I cannot proceed'.

This paper discusses the views of 17 healthcare practitioners involved with transplantation on the ethics of live liver donations (LLDs). Donations between emotionally related donor and recipients (especially from parents to their children) increased the acceptability of an LLD compared with those between strangers. Most healthcare professionals (HCPs) disapproved of altruistic stranger donations, considering them to entail an unacceptable degree of risk taking. Participants tended to emphasise the need to balance the harms of proceeding against those of not proceeding, rather than calculating the harm-to-benefits ratio of donor versus recipient. Participants' views suggested that a complex process of negotiation is required, which respects the autonomy of donor, recipient and HCP. Although they considered that, of the three, donor autonomy is of primary importance, they also placed considerable weight on their own autonomy. Our participants suggest that their opinions about acceptable risk taking were more objective than those of the recipient or donor and were therefore given greater weight. However, it was clear that more subjective values were also influential. Processes used in live kidney donation (LKD) were thought to be a good model for LLD, but our participants stressed that there is a danger that patients may underestimate the risks involved in LLD if it is too closely associated with LKD.

How severe is diabetes after total pancreatectomy? A case-matched analysis.

OBJECTIVES: Total pancreatectomy (TP) is associated with significant morbidity and mortality. The severity of postoperative diabetes and existence of 'brittle diabetes' are unclear. This study sought to identify quality of life (QoL) and diabetes-specific outcomes after TP. METHODS: Patients who underwent TP were matched for age, sex and duration of diabetes with patients with type 1 diabetes. General QoL was assessed using the European Organization for Research and Treatment of Cancer (EORTC) core quality of life questionnaire QLQ-C30 and the PAN26 tool. Diabetes-specific outcomes were assessed using the Problem Areas in Diabetes (PAID) tool and an assessment of diabetes-specific complications and outcomes. RESULTS: A total of 123 patients underwent TP; 88 died (none of diabetic complications) and two were lost to follow-up. Of the remaining 33 patients, 28 returned questionnaires. Fourteen general and pancreas-specific QoL measurements were all significantly worse amongst the TP cohort (QLQ-C30 + PAN26). However, when diabetes-specific outcomes were compared using the PAID tool, only one of 20 was significantly worse. HbA1c values were comparable (P = 0.299), as were diabetes-related complications such as hypoglycaemic attacks and organ dysfunction. CONCLUSIONS: Total pancreatectomy is associated with impaired QoL on general measures compared with that in type 1 diabetes patients. Importantly, however, there was almost no significant difference in diabetes-specific outcomes as assessed by a diabetes-specific questionnaire, or in diabetes control. This study does not support the existence of 'brittle diabetes' after TP.

A preoperative predictive score of pancreatic fistula following pancreatoduodenectomy.

BACKGROUND: Various factors are related to the occurrence of postoperative pancreatic fistula (POPF) following pancreatoduodenectomy (PD). Some of the strongest are identified intra- or postoperatively, which limits their utility in predicting this complication. The preoperative prediction of POPF permits an individualized approach to patient consent and selection, and may influence postoperative management. This study sought to develop and test a score to predict POPF. METHODS: A post hoc analysis of a prospectively maintained database was conducted. Consecutive patients were randomly selected to modelling and validation sets at a ratio of 2 :1, respectively. Patient data, preoperative blood tests and physical characteristics of the gland (assessed from preoperative computed tomography images) were subjected to univariate and multivariate analysis in the modelling set of patients. A score predictive of POPF was designed and tested in the validation set. RESULTS: Postoperative pancreatic fistula occurred in 77 of 325 (23.7%) patients. The occurrence of POPF was associated with 12 factors. On multivariate analysis, body mass index and pancreatic duct width were independently associated with POPF. A risk score to predict POPF was designed (area under the receiver operating characteristic curve: 0.832, 95% confidence interval 0.768-0.897; P < 0.001) and successfully tested upon the validation set. CONCLUSIONS: Preoperative assessment of a patient's risk for POPF is possible using simple measurements. The present risk score is a valid tool with which to predict POPF in patients undergoing PD.

Intercurrent infection predicts mortality in patients with late hepatic artery thrombosis listed for liver retransplantation.

Liver retransplantation for late hepatic artery thrombosis (HAT) is considered the treatment of choice for select patients. Nevertheless, there is a paucity of data to aid decision making in this setting. The aims of this single-center study of patients listed for late HAT were (1) to determine variables associated with wait-list mortality, (2) to describe survival after retransplantation, and (3) to determine variables associated with mortality after retransplantation. Seventy-eight patients were diagnosed with late HAT (incidence = 3.9%). Of the 49 patients listed for retransplantation, 9 died on the waiting list and 36 were retransplanted. The estimated 1-year survival after listing for retransplantation was 53.7%. Only multidrug-resistant (MDR) bacteria-positive cultures were predictive of wait-list mortality (P = 0.01). After retransplantation, the estimated 1- and 5-year patient survival was 71.9% and 62.5%, respectively. Increasing Model for End-Stage Liver Disease score (overall P = 0.007), MDR bacteria-positive cultures (P = 0.047), and continued antibiotic therapy (P = 0.001) at the time of retransplantation were risk factors for post retransplant death. In conclusion, patients who undergo liver retransplantation for late HAT have satisfactory outcomes. However, the presence of active infection and MDR bacteria-positive cultures should be taken into account when risk stratifying such patients.

Liver transplantation for acute intermittent porphyria is complicated by a high rate of hepatic artery thrombosis.

Acute intermittent porphyria (AIP) is an autosomal-dominant condition resulting from a partial deficiency of the ubiquitously expressed enzyme porphobilinogen deaminase. Although its clinical expression is highly variable, a minority of patients suffer recurrent life-threatening neurovisceral attacks despite optimal medical therapy. Because the liver is the major source of excess precursor production, liver transplantation (LT) represents a potentially effective treatment for severely affected patients. Using data from the U.K. Transplant Registry, we analyzed all transplants performed for AIP in the United Kingdom and Ireland. Between 2002 and 2010, 10 patients underwent LT for AIP. In all cases, the indication for transplantation was recurrent, biochemically proven, medically nonresponsive acute attacks of porphyria resulting in significantly impaired quality of life. Five patients had developed significant neurological morbidities such as paraplegia before transplantation. The median follow-up time was 23.4 months, and there were 2 deaths from multiorgan failure at 98 days and 26 months. Eight recipients were alive for 3.2 to 109 months after transplantation. Complete biochemical and symptomatic resolution was observed in all patients after transplantation. However, there was a high rate of hepatic artery thrombosis (HAT; 4/10), with 1 patient requiring regrafting. The effects of previous neuronal damage such as joint contractures were not improved by transplantation. Thus, impaired quality of life in the surviving patients was usually a result of preoperative complications. Refractory AIP is an excellent indication for LT, and long-term outcomes for carefully selected patients are good. There is, however, an increased incidence of HAT in these patients, and we recommend routine antiplatelet therapy after transplantation.

Aetio-pathogenesis and the management of spontaneous liver bleeding in the West: a 16-year single-centre experience.

BACKGROUND: Spontaneous liver bleeding (SLB) is a rare but potentially fatal complication. In contrast to the East, various benign pathologies are the source of SLB in the West. An accurate diagnosis and a timely implementation of appropriate treatment are crucial in the management of these patients. The present study presents a large Western experience of SLB from a specialist liver centre. METHODS: A retrospective analysis of patients presented with SLB between January 1995 and January 2011. RESULTS: Sixty-seven patients had SLB, 44 (66%) were female and the median age at presentation was 47 years. Abrupt onset upper abdominal pain was the presenting symptom in 65 (97%) patients. The aetiology for SLB was hepatic adenoma in 27 (40%), hepatocellular carcinoma (HCC) in 17 (25%) and various other liver pathologies in the rest. Emergency treatment included a conservative approach in 42 (64%), DSA and embolization in 6 (9%), a laparotomy and packing in 6 (9%) and a liver resection in 11 (16%) patients. Eleven (16%) patients had further planned treatments. Seven (10%) died during the same admission but the mortality was highest in patients with HELLP syndrome. At a median follow-up of 54 months all patients with benign disease are alive. The 1-, 3- and 5-year survival of patients with HCC was 59%, 35% and 17%, respectively. CONCLUSION: SLB is a life-threatening complication of various underlying conditions and may represent their first manifestation. The management should include initial haemostasis followed by appropriate staging investigations to provide a definitive treatment for each individual patient.

Specialist early and immediate repair of post-laparoscopic cholecystectomy bile duct injuries is associated with an improved long-term outcome.

INTRODUCTION: A majority of bile duct injuries (BDI) sustained during laparoscopic cholecystectomy require formal surgical reconstruction, and traditionally this repair is performed late. We aimed to assess long-term outcomes after repair, focusing on our preferred early approach. METHODS: A total of 200 BDI patients [age 54(20-83); 64 male], followed up for median 60 (5-212) months were assessed for morbidity. Factors contributing to this were analyzed with a univariate and multivariate analysis. RESULTS: A total of 112 (56%) patients were repaired by specialist hepatobiliary surgeons [timing of repair: immediate, n = 28; early (<21 days), n = 43; and late (>21 days) n = 41], whereas 45 (22%) underwent repair by nonspecialist surgeons before specialist referral [immediate, n = 16; early, n = 26 and late, n = 03]. Outcomes after immediate and early repairs were comparable to late repairs when performed by specialists [recurrent cholangitis:11%, 12%, and 10%; P = 0.96, NS; re-stricture:18%,5%, and 29%; P = 0.01; nonsurgical intervention: 14%, 5%, and 24%; P<0.03; redo surgery: 4%, 2%, and 5%; P = 0.81, NS; overall morbidity: 21%, 14%, and 39%; P<0.02]. On multivariate analysis, immediate and early repairs done by nonspecialist surgeons were independent risk factors (P < 0.05) for recurrent cholangitis [50% and 27%], re-stricturing (75% and 61%), redo reconstructions (31% and 61%), and overall morbidity (75% and 84%). CONCLUSION: Immediate and early repair after BDI results in comparable, if not better long-term outcomes compared to late repair when performed by specialists.

Preoperative localisation and surgical management of insulinoma: single centre experience.

BACKGROUND: The majority of insulinomas are benign, small and intrapancreatic. Preoperative localisation is important to plan the surgical management. METHODS: We retrospectively analysed our data on the preoperative imaging, type of surgery and histopathological features of the operated patients with an insulinoma from January 1993 to March 2010. Univariate and multivariate analyses were performed to detect the predictive factors for survival following surgery. RESULTS: Forty patients were operated on for insulinoma, of which 33 were benign and 7 were malignant. The sensitivity of preoperative computed tomogram scan, magnetic resonance imaging and endoscopic ultrasound, for localising the lesions was 62, 82 and 94%, respectively. Enucleation was performed in 21 (52.5%) patients, and remaining had pancreatic resection. Hepatic resection was performed in 2 and liver transplantation in 1 patient. Morbidity and perioperative mortality was 17 (42.5%) and 1 (2.7%), respectively. The overall 5- and 10-year survival was 89 and 86.5%, respectively. The presence of metastases was found to be an independent predictor of poor survival on multivariate analysis. CONCLUSION: Preoperative computed tomogram/magnetic resonance imaging and endoscopic ultrasound are sensitive in localizing the majority of insulinomas. Surgery offers a good long-term survival, even in patients with malignant insulinoma.

Outcomes comparing a pancreaticogastrostomy (PG) and a pancreaticojejunostomy (PJ) after a pancreaticoduodenectomy (PD).

BACKGROUND: The advantage of a pancreaticogastrostomy (PG) over a pancreaticojejunostomy (PJ) after a pancreaticoduodenectomy (PD) is not clear. AIM: The aim of the present study was to compare the pancreatic fistula (PF, defined according to the International Study Group for Pancreatic Fistula classification) rate and other complications between both methods. METHODS: Retrospective analysis of prospectively collected data of 424 [median: 65 years (17-83)] patients who underwent PG (239, 56.4%) and PJ (185, 43.6%) reconstruction between January 2005 and December 2009. RESULTS: PF occurred in 55 (23.5%) in the PG and 30 (16.2%, P= 0.067) patients in the PJ group. Grade A PF occurred in 19 (7.9%), B in 22 (9.2%) and C in 14 (5.8%) in the PG compared with 5 (2.7%), 12 (6.5%) and in 13 (7.0%), respectively, in the PJ group. The median hospital was 10 days in both groups. The morbidity was higher in the PG group (108, 45.2 vs. 62, 33.5%, P= 0.015). However, there was no significant difference in the 90-day mortality between both groups (PG-17, 7.0% vs. PJ-16, 8.6%, P= 0.558). CONCLUSION: There was no difference in the overall PF rate, hospital stay and overall mortality between PG and PJ reconstruction methods. However, the grade A PF rate was higher in the PG group.

Pulmonary thromboembolism in liver transplantation: a retrospective review of the first 25 years.

The evidence on the state of 'haemostasis' at the time of liver transplantation (LT) is conflicting, with recent publications that suggest a hypercoagulable state, in contrast to traditionally held views. These findings raise the issue of thrombo-embolic complications after LT, an area of interest which has received little attention in recent published literature. We therefore conducted a retrospective review of our experience of 3000 liver transplants over 25 years. Our prospective transplant database was reviewed to find all patients who were suspected to have had a pulmonary embolism (PE) during or following LT. Paediatric transplants were excluded. A part of this database was cross referenced against hospital records to corroborate its accuracy. Clinical records of all these patients were reviewed and relevant aspects collated and analyzed. Following exclusion of the paediatric recipients, 2 149 adults were reviewed to find 36 patients in whom a PE was suspected (median age 49), 21 of whom were within 90 days of transplant (median duration 22 days). PE was ruled out in 10, unconfirmed in two, confirmed in eight patients; and in one, air embolism was found. All PEs occurred in hospital, but aetiology of liver failure was varied. Of note, two patients died of an on-table PE and one patient of chronic rejection/disease recurrence (Primary Sclerosing Cholangitis). The remaining five are still alive (median survival of 65 months). Although thromboprophylaxis is now routine in our unit, its use in these patients could not be confirmed from records available. Fifteen PE were suspected and confirmed after 90 days from transplant (six within, and nine out with the first year). Acute PE in the setting of LT has an incidence rate in our series of 0.37% that would appear to be lower than previously reported and lower than one would expect after a 'major complex' category operation. This potentially suggests that the overall haemostatic function in these patients is still weighted towards hypocoagulation with the resultant risk of excessive bleeding. Aetiology of liver disease did not seem to confer a higher risk in our series. The prognosis after post-operative PE appears good although sudden death due to an on-table embolism is a rare but significant risk.

A reaudit of specialist-managed liver trauma after establishment of regional referral and management guidelines.

BACKGROUND: An earlier liver trauma audit (52 patients) noted that 50% were surgically managed at referring hospitals with a high morbidity and mortality, after which a regional referral and management algorithm was implemented in 2001. This study aims to reaudit specialist-managed liver trauma outcomes. METHODS: Prospective analysis of 99 patients (68 male) treated for liver injury (LI) between 2001 and 2008. Patient characteristics, management, and outcome results of these were compared with the results of previous audit. LI severity was determined by computed tomography, operative findings, and classified according to liver Organ Injury Scale. RESULTS: As implementation of guidelines, referrals increased from 5.2 patients/yr to 14.1 patients/yr, while LI profile was unchanged. Fewer patients were managed surgically with lower surgical intervention at referring hospitals (26 of 52 [50%] vs. 29 of 77 [38%]; p = 0.2). There has been a decrease in liver resection rates (14 of 26 [54%] vs. 3 of 37 [8%]; p = 0.0001]), overall mortality rate (12 of 52 [23%] vs. 11 of 99 [11%]; p = 0.059), and postoperative deaths. CONCLUSION: This reaudit confirms the role of nonoperative management of liver trauma. Early use of computed tomography scan with specialist discussion, selective use of perihepatic packing, and transfer to a specialist unit should be standard practice in the management of complex liver trauma.

Liver retransplantation in adults: a single-centre, 25-year experience.

BACKGROUND: Retransplantation is the only form of treatment for patients with irreversible graft failure. The aim of this study was to analyse a single centre's experience of the indications for and outcomes of retransplantation. METHODS: A total of 196 patients who underwent liver retransplantation using 225 grafts, between January 1982 and July 2007, were included in the study. The following parameters were analysed: patient demographics; primary diagnosis; distribution of retransplantation over different time periods; indications for retransplantation; time interval to retransplantation, and overall patient and graft survival. RESULTS: Of the 2437 primary orthotopic liver transplantations, 196 patients (8%) required a first regraft, 23 patients (1%) a second regraft and six patients (0.25%) a third regraft. Autoimmune hepatitis was the most common primary diagnosis for which retransplantation was required (12.7% of primary transplantations). The retransplantation rate declined from 12% at the beginning of our programme to 7.6% at the end of the study period. The most common indication for retransplantation was hepatic artery thrombosis (31.6%). Nearly two-thirds of the retransplantations were performed within 6 months of the primary transplantation. The 1-, 3-, 5- and 10-year patient survival rates following first retransplantation were 66%, 61%, 57% and 47%, respectively. Five-year survival after second retransplantation was 40%. None of the patients have yet survived 3 years after a third regraft. Donor age of < or =55 years and a MELD (Model for End-stage Liver Disease) score of < or =23 were associated with better outcome following retransplantation. CONCLUSIONS: First retransplantation was associated with good longterm survival. There was no survival benefit following second and third retransplantations. A MELD score of < or =23 and donor age of < or =55 years correlated with better outcome following retransplantation.

Longitudinal quality of life data can provide insights on the impact of adjuvant treatment for pancreatic cancer-Subset analysis of the ESPAC-1 data.

The European Study Group for Pancreatic Cancer (ESPAC-1) study is the largest study of adjuvant treatment for pancreatic ductal adenocarcinoma to date and confirmed a survival advantage for adjuvant chemotherapy but not for chemoradiation. The importance of parallel evaluation of survival and quality of life (QoL) has been recognized as fundamental and the aim was to assess QoL and quality adjusted survival. A longitudinal QoL study on a subset of ESPAC-1 patients who prospectively completed the EORTC QLQ C-30 questionnaire during treatment and follow-up. An integrated quality-survival product method was used to adjust any treatment effect on survival by a function of measured QoL, calculated over a restricted 24-month-period (QALM-24). Three hundred and sixteen patients completed 1,201 questionnaires. There were no differences between treatment groups in dimension scores at baseline (randomization). For the chemotherapy group, the mean Quality Adjusted Life Months over 24 months (QALM-24) was 9.6 (95% CI: 8.7, 11.2) months compared with the mean QALM-24 of 8.6 (95% CI: 7.6, 10.5) months for the no chemotherapy group. For the chemoradiation group, the mean QALM-24 was 7.1 (95% CI: 6.0, 9.0) months compared with the mean QALM-24 of 8.1 (95% CI: 7.0, 10.0) months for the no chemoradiation group. The previously reported survival advantage supporting the use of adjuvant chemotherapy is maintained when adjusted using quality adjusted survival methodology. Chemotherapy provided on average an additional 1.0 quality-adjusted life months within a restricted 2-year time period from the time of resection.

Long-term outcome after sequential resections of liver and lung metastases from colorectal carcinoma.

BACKGROUND: Surgical resection of colorectal liver metastases (CLM) is an established form of treatment. Limited data exists on the value of sequential hepatic and pulmonary metastasectomy. We analysed patients who underwent sequential liver and lung resections for CLM. METHODS: A total of 910 patients who underwent liver resection for CLM between January 2000 and December 2007, were analysed to identify patients with resectable pulmonary metastases (n= 43; 4.7%). Patient demographics, overall survival and survival difference between synchronous and metachronous pulmonary metastasectomy groups were compared. In addition, outcomes in the 'liver and lung resection' group were compared with a matched group of 'liver resection only' patients (matched for age, primary disease stage, interval to liver resection and liver disease stage). RESULTS: Forty-three patients (median age 62, range 43-83 years, 22 males) underwent sequential liver and lung resection. A total of 36 patients underwent major hepatic resections, 18 patients had bilobar disease and the median number of liver lesions resected was 3 (range 1-5 lesions). Ten patients had synchronous liver and lung metastases. The median interval between liver and lung metastasectomy was 25 months (range 2-88 months). A total of two patients underwent major lobectomies, three patients had bilateral disease and the median number of lung lesions resected was one (range 1-3). The 1-, 3- and 5-year overall survival rates after first metastasectomy were 100%, 87.1% and 53.9%, respectively, with a median survival of 42 months. PATIENTS: Undergoing metachronous pulmonary metastasectomy had better 1-, 3- and 5-year survival rates than those with synchronous disease (100%, 88.9% and 60.9% vs. 100%, 75% and 0%, respectively; P= 0.02, log rank test). There was no significant survival difference between the 'liver and lung resection' and the 'liver resection only' groups. CONCLUSION: Sequential liver and lung resection for CLM is associated with good long-term survival in selected patients, except in those presenting with synchronous lung and liver metastases.

Wrap choice during fundoplication.

Gastro-oesphageal reflux disease is an increasing health burden. The mainstay of treatment has conventionally been medical therapy but since the introduction of laparoscopic surgery laparoscopic anti-reflux surgery has been increasingly used for intractable symptoms or in patients unwilling to take long term medication. The Nissen 360 degree wrap has traditionally been considered the gold standard operation but can be associated with significant complications. These complications include "gas bloat" and dysphagia and can occur relatively frequently. Various modifications have been described to the original operation and some of these have been described. In addition alternative wraps have been described which seem to have a reduced incidence of complications associated with their use. This editorial discusses the various types of wrap that can be performed and the minimum requirements of the surgical technique. The evidence from a recent meta-analysis of the randomised data has suggested that an anterior wrap is associated with a lower rate of complications and gives just as good control of reflux symptoms. The advantages and disadvantages of an anterior wrap are discussed. The lack of long term follow up data concerns some practitioners and at the moment the choice of wrap carried out still rests with the individual surgeon.
