The clinical implication of minimally invasive versus open pancreatoduodenectomy for non-pancreatic periampullary cancer: a systematic review and individual patient data meta-analysis.

BACKGROUND: Most studies on minimally invasive pancreatoduodenectomy (MIPD) combine patients with pancreatic and periampullary cancers even though there is substantial heterogeneity between these tumors. Therefore, this study aimed to evaluate the role of MIPD compared to open pancreatoduodenectomy (OPD) in patients with non-pancreatic periampullary cancer (NPPC). METHODS: A systematic review of Pubmed, Embase, and Cochrane databases was performed by two independent reviewers to identify studies comparing MIPD and OPD for NPPC (ampullary, distal cholangio, and duodenal adenocarcinoma) (01/2015-12/2021). Individual patient data were required from all identified studies. Primary outcomes were (90-day) mortality, and major morbidity (Clavien-Dindo 3a-5). Secondary outcomes were postoperative pancreatic fistula (POPF), delayed gastric emptying (DGE), postpancreatectomy hemorrhage (PPH), blood-loss, length of hospital stay (LOS), and overall survival (OS). RESULTS: Overall, 16 studies with 1949 patients were included, combining 928 patients with ampullary, 526 with distal cholangio, and 461 with duodenal cancer. In total, 902 (46.3%) patients underwent MIPD, and 1047 (53.7%) patients underwent OPD. The rates of 90-day mortality, major morbidity, POPF, DGE, PPH, blood-loss, and length of hospital stay did not differ between MIPD and OPD. Operation time was 67 min longer in the MIPD group (P = 0.009). A decrease in DFS for ampullary (HR 2.27, P = 0.019) and distal cholangio (HR 1.84, P = 0.025) cancer, as well as a decrease in OS for distal cholangio (HR 1.71, P = 0.045) and duodenal cancer (HR 4.59, P < 0.001) was found in the MIPD group. CONCLUSIONS: This individual patient data meta-analysis of MIPD versus OPD in patients with NPPC suggests that MIPD is not inferior in terms of short-term morbidity and mortality. Several major limitations in long-term data highlight a research gap that should be studied in prospective maintained international registries or randomized studies for ampullary, distal cholangio, and duodenum cancer separately.

Liver transplantation for HCC: validation of prognostic power of the RETREAT score for recurrence in a UK cohort.

BACKGROUND: The Risk Estimation of Tumor Recurrence After Transplant (RETREAT) score as a prognostic index for recurrence has been reported previously and has not been validated outside the USA. Our study has validated the score in a single center UK cohort of patients being transplanted for HCC. METHODS: LT for HCC between 2008 and 2018 at our center were analyzed. Recurrence-free survival (RFS) was compared by the RETREAT score and validated using Net Reclassification Improvement (NRI) by comparing it to Milan criteria. RESULTS: 346 adult HCC patients were transplanted of whom 313 were included. 28 (8.9%) had a recurrence. Summation of largest diameter and total number of viable tumors (HR = 1.19, p < 0.001), micro-/macro-vascular invasion (HR = 3.74, p = 0.002) and AFP>20 ng/ml (HR = 3.03, p = 0.005) were associated with recurrence on multivariate analysis. RFS decreased with increasing RETREAT score (log-rank p = 0.016). RETREAT performed better than Milan with significant NRI at 1- and 2-years post-transplant (0.43 (p = 0.004) and 0.38 (p = 0.03) respectively). CONCLUSION: LT outcomes using the revised UK criteria are equivalent to Milan criteria. Further, RETREAT score was validated as a prognostic index for the first time in a UK cohort and may assist risk stratification, selection for adjuvant therapies and guide surveillance.

Pure laparoscopic versus open donor hepatectomy for adult living donor liver transplantation - A systematic review and meta-analysis.

BACKGROUND: Pure laparoscopic donor hepatectomy (PLDH) for adult living donor liver transplantation (LDLT) remains controversial. The aim of this study was to undertake a systematic review and meta-analysis of donor outcomes following PLDH for adult LDLT. MATERIALS AND METHODS: Systematic review in line with the meta-analysis of observational studies in epidemiology guidelines. RESULTS: Eight studies were included in the systematic review and six in the meta-analysis. A total of 575 donors underwent PLDH for adult LDLT. The mean donor age was 32.8 years with a BMI of 23.4 kg/m2 and graft weight of 675 g. The mean operative time was 353 min and the conversion rate was 2.8% (n = 16). Overall morbidity was 10.8% with 1.6% major complications (Clavien-Dindo grade 3b), zero mortality and 9.0 days length of stay (LOS). The meta-analysis demonstrated that the operative time was significantly shorter for the open donor hepatectomy group (mean difference 29.15 min; P = 0.006) and the LOS was shorter for the PLDH group (mean difference -0.73 days; P = 0.02), with a trend towards lesser estimated blood loss in PLDH group. However, no difference between the two groups was noted in terms of overall morbidity or major complications. CONCLUSIONS: Perioperative outcomes of PLDH are similar to the standard open approach in highly specialised centers with trend towards lesser blood loss and overall shorter hospital stay. Careful donor selection and standardisation of the technique are imperative for the successful implementation and adoption of the procedure worldwide.

A matched-pair analysis of laparoscopic versus open pancreaticoduodenectomy: oncological outcomes using Leeds Pathology Protocol.

BACKGROUND: Laparoscopic pancreaticoduodenectomy (LPD) is a safe procedure. Oncological safety of LPD is still a matter for debate. This study aimed to compare the oncological outcomes, in terms of adequacy of resection and recurrence rate following LPD and open pancreaticoduodenectomy (OPD). METHODS: Between November 2005 and April 2009, 12 LPDs (9 ampullary and 3 distal common bile duct tumors) were performed. A cohort of 12 OPDs were matched for age, gender, body mass index (BMI) and American Society of Anesthesiologists (ASA) score and tumor site. RESULTS: Mean tumor size LPD vs OPD (19.8 vs 19.2 mm, P=0.870). R0 resection was achieved in 9 LPD vs 8 OPD (P=1.000). The mean number of metastatic lymph nodes and total number resected for LPD vs OPD were 1.1 vs 2.1 (P=0.140) and 20.7 vs 18.5 (P=0.534) respectively. Clavien complications grade I/II (5 vs 8), III/IV (2 vs 6) and pancreatic leak (2 vs 1) were statistically not significant (LPD vs OPD). The mean high dependency unit (HDU) stay was longer in OPD (3.7 vs 1.4 days, P<0.001). There were 2 recurrences each in LPD and OPD (log-rank, P=0.983). Overall mortality for LPD vs OPD was 3 vs 6 (log-rank, P=0.283) and recurrence-related mortality was 2 vs 1. There was one death within 30 days in the OPD group secondary to severe sepsis and none in the LPD group. CONCLUSIONS: Compared to open procedure, LPD achieved a similar rate of R0 resection, lymph node harvest and long-term recurrence for tumors less than 2 cm. Though technically challenging, LPD is safe and does not compromise oncological outcome.

Laparoscopic Versus Open Hemihepatectomy: The ORANGE II PLUS Multicenter Randomized Controlled Trial.

PURPOSE: To compare outcomes after laparoscopic versus open major liver resection (hemihepatectomy) mainly for primary or metastatic cancer. The primary outcome measure was time to functional recovery. Secondary outcomes included morbidity, quality of life (QoL), and for those with cancer, resection margin status and time to adjuvant systemic therapy. PATIENTS AND METHODS: This was a multicenter, randomized controlled, patient-blinded, superiority trial on adult patients undergoing hemihepatectomy. Patients were recruited from 16 hospitals in Europe between November 2013 and December 2018. RESULTS: Of the 352 randomly assigned patients, 332 patients (94.3%) underwent surgery (laparoscopic, n = 166 and open, n = 166) and comprised the analysis population. The median time to functional recovery was 4 days (IQR, 3-5; range, 1-30) for laparoscopic hemihepatectomy versus 5 days (IQR, 4-6; range, 1-33) for open hemihepatectomy (difference, -17.5% [96% CI, -25.6 to -8.4]; P < .001). There was no difference in major complications (laparoscopic 24/166 [14.5%] v open 28/166 [16.9%]; odds ratio [OR], 0.84; P = .58). Regarding QoL, both global health status (difference, 3.2 points; P < .001) and body image (difference, 0.9 points; P < .001) scored significantly higher in the laparoscopic group. For the 281 (84.6%) patients with cancer, R0 resection margin status was similar (laparoscopic 106 [77.9%] v open 122 patients [84.1%], OR, 0.60; P = .14) with a shorter time to adjuvant systemic therapy in the laparoscopic group (46.5 days v 62.8 days, hazard ratio, 2.20; P = .009). CONCLUSION: Among patients undergoing hemihepatectomy, the laparoscopic approach resulted in a shorter time to functional recovery compared with open surgery. In addition, it was associated with a better QoL, and in patients with cancer, a shorter time to adjuvant systemic therapy with no adverse impact on cancer outcomes observed.

Increased morbidity in overweight and obese liver transplant recipients: a single-center experience of 1325 patients from the United Kingdom.

Obesity levels in the United Kingdom have risen over the years. Studies from the United States and elsewhere have reported variable outcomes for obese liver transplant recipients in terms of post-liver transplant morbidity, mortality, and graft survival. This study was designed to analyze the impact of the body mass index (BMI) on outcomes following adult liver transplantation. Data from 1994 to 2009 were retrieved from a prospectively maintained database. Patients were stratified into 5 World Health Organization BMI categories: underweight (<18.5 kg/m(2)), normal weight (18.5-24.9 kg/m(2)), overweight (25.0-29.9 kg/m(2)), obese (30.0-34.9 kg/m(2)), and morbidly obese (≥35.0 kg/m(2)). The primary outcome was an evaluation of graft and patient survival, and the secondary outcome was an assessment of postoperative morbidity. Bonferroni correction was applied with statistical significance set at P < 0.012. Kaplan-Meier curves were used to study the effects of BMI on graft and patient survival. A total of 1325 patients were included in the study: underweight (n = 47 or 3.5%), normal-weight (n = 643 or 48.5%), overweight (n = 417 or 31.5%), obese (n = 145 or 10.9%), and morbidly obese patients (n = 73 or 5.5%). The rate of postoperative infective complications was significantly higher in the overweight (60.7%, P < 0.01) and obese recipients (65.5%, P < 0.01) versus the normal-weight recipients (50.4%). The morbidly obese patients had a longer mean intensive care unit (ICU) stay than the normal-weight patients (4.7 versus 3.2 days, P = 0.03). The mean hospital stay was longer for the overweight (22.4 days, P < 0.001), obese (21.3 days, P = 0.04), and morbidly obese recipients (22.4 days, P = 0.047) versus the normal-weight recipients (18.0 days). There was no difference in death-censored graft survival or patient survival between the groups. In conclusion, this is the largest and only reported UK series on BMI and outcomes following liver transplantation. Overweight and obese patients have significantly increased morbidity in terms of infective complications after liver transplantation and, consequently, longer ICU and hospital stays.

Results of pancreatic surgery in the elderly: is age a barrier?

BACKGROUND: By 2033, the number of people aged 85 years and over in the UK is projected to double, accounting for 5% of the total population. It is important to understand the surgical outcome after a pancreatic resection in the elderly to assist decision making. METHODS: Over a 9-year period (from January 2000 to August 2009), 428 consecutive patients who underwent a pancreatic resection were reviewed. Data were collected on mortality, complications, length of stay and survival. Patients were divided into two groups (younger than 70 and older than 70 years old) and outcomes were analysed. RESULTS: In all, 119 (27.8%) patients were ≥ 70 years and 309 (72.2%) patients were < 70 years. The median length of stay for the older and younger group was 15 days (range 3-91) and 14 days (range 3-144), respectively. The overall mortality was 3.4% in the older group and 2.6% in the younger group (P = 0.75). The older cohort had a cumulative median survival of 57.3 months (range 0-119), compared with 78.7 months (range 0-126) in the younger cohort (P < 0.0001). In patients undergoing a pancreatic resection for ductal adenocarcinoma and cholangiocarcinoma there was a significant difference in survival with P-values of 0.043 and 0.003, respectively. For ampullary adenocarcinoma, the older group had a median survival of 47.1 months compared with 68.3 months (P = 0.194). CONCLUSION: Results from this study suggest that while elderly patients can safely undergo a pancreatic resection and that age alone should not preclude a pancreatic resection, there is still significant morbidity and mortality in the octogenarian subgroup with poor long-term survival with the need for quality-of-life assessment.

The positive impact of the COVID 19 pandemic on organ utilisation in liver transplantation.

Background: As the world recovers from the aftermath of devastating waves of an outbreak, the ongoing Coronavirus disease 2019 pandemic has presented a unique perspective to the transplantation community of ''organ utilisation'' in liver transplantation, a poorly defined term and ongoing hurdle in this field. To this end, we report the key metrics of transplantation activity from a high-volume liver transplantation centre in the United Kingdom over the past two years. Methods: Between March 2019 and February 2021, details of donor liver offers received by our centre from National Health Service Blood & Transplant, and of transplantation were reviewed. Differences in the activity before and after the outbreak of the pandemic, including short term post-transplant survival, have been reported. Results: The pandemic year at our centre witnessed a higher utilisation of Donation after Cardiac Death livers (80.4% vs. 58.3%, p = 0.016) with preserved United Kingdom donor liver indices and median donor age (2.12 vs. 2.02, p = 0.638; 55 vs. 57 years, p = 0.541) when compared to the pre-pandemic year. The 1- year patient survival rates for recipients in both the periods were comparable. The pandemic year, that was associated with increased utilisation of Donation after Cardiac Death livers, had an ischaemic cholangiopathy rate of 6%. Conclusions: The pressures imposed by the pandemic led to increased utilisation of specific donor livers to meet patient needs and minimise the risk of death on the waiting list, with apparently preserved early post-transplant survival. Optimum organ utilisation is a balancing act between risk and benefit for the potential recipient, and technologies like machine perfusion may allow surgeons to increase utilisation without compromising patient outcomes.

Laparoscopic versus open resections in the posterosuperior liver segments within an enhanced recovery programme (ORANGE Segments): study protocol for a multicentre randomised controlled trial.

BACKGROUND: A shift towards parenchymal-sparing liver resections in open and laparoscopic surgery emerged in the last few years. Laparoscopic liver resection is technically feasible and safe, and consensus guidelines acknowledge the laparoscopic approach in the posterosuperior segments. Lesions situated in these segments are considered the most challenging for the laparoscopic approach. The aim of this trial is to compare the postoperative time to functional recovery, complications, oncological safety, quality of life, survival and costs after laparoscopic versus open parenchymal-sparing liver resections in the posterosuperior liver segments within an enhanced recovery setting. METHODS: The ORANGE Segments trial is an international multicentre randomised controlled superiority trial conducted in centres experienced in laparoscopic liver resection. Eligible patients for minor resections in the posterosuperior segments will be randomised in a 1:1 ratio to undergo laparoscopic or open resections in an enhanced recovery setting. Patients and ward personnel are blinded to the treatment allocation until postoperative day 4 using a large abdominal dressing. The primary endpoint is time to functional recovery. Secondary endpoints include intraoperative outcomes, length of stay, resection margin, postoperative complications, 90-day mortality, time to adjuvant chemotherapy initiation, quality of life and overall survival. Laparoscopic liver surgery of the posterosuperior segments is hypothesised to reduce time to functional recovery by 2 days in comparison with open surgery. With a power of 80% and alpha of 0.04 to adjust for interim analysis halfway the trial, a total of 250 patients are required to be randomised. DISCUSSION: The ORANGE Segments trial is the first multicentre international randomised controlled study to compare short- and long-term surgical and oncological outcomes of laparoscopic and open resections in the posterosuperior segments within an enhanced recovery programme. TRIAL REGISTRATION: ClinicalTrials.gov NCT03270917 . Registered on September 1, 2017. Before start of inclusion. PROTOCOL VERSION: version 12, May 9, 2017.

Index admission laparoscopic cholecystectomy for patients with acute biliary symptoms: results from a specialist centre.

BACKGROUND: Index admission laparoscopic cholecystectomy (ALC) is the treatment of choice for patients admitted with biliary symptoms but is performed in less than 15% of these admissions. We analysed our results for ALC within a tertiary hepatobiliary centre. METHODS: Data from all cholecystectomies carried out under the care of the two senior authors from 1998 to 2008 were prospectively collected and interrogated. RESULTS: 1710 patients underwent cholecystectomy of which 439 (26%) were ALC. Patients operated on acutely did not have a significantly different complication rate (P= 0.279; 4% vs.3%). Factors predicting complications were abnormal alkaline phosphatase (ALP) (P= 0.037), dilated common bile duct (CBD) (P= 0.026), cholangitis (P= 0.040) and absence of on table cholangiography (OTC) (P= 0.011). There were no bile duct injuries. Patients undergoing ALC had a higher rate of conversion to an open procedure (P < 0.001:10% vs.3%). The proportion of complicated disease was higher in the ALC group (P < 0.001; 70% vs.31%). Only complicated disease (P= 0.006), absence of OTC (P < 0.001) and age greater than 65 years (P < 0.001) were predictive of conversion on multivariate analysis. CONCLUSIONS: Laparoscopic cholecystectomy can be performed safely in patients with acute biliary symptoms and should be considered the gold standard for management of these patients thus avoiding avoidable readmissions and life-threatening complications. A higher conversion rate to an open procedure must be accepted when treating more complicated disease. It is the severity of disease rather than timing of surgery which most probably predicts complications and conversions.

A Novel Technique for Pancreatic Stump Closure: Clip Ligation of the Duct and Associated Suturing of Pancreas.

Pancreatic fistula (PF) remains the primary source of morbidity after distal pancreatectomy (DP). There is currently no optimal stump closure technique to reduce PF rates. We present a novel technique for pancreatic stump closure using Clip Ligation of the duct and Associated Suturing of Pancreas (CLASP). Five patients (three females) with a median age of 65 years underwent DP and splenectomy for pancreatic body or tail tumour using the CLASP technique. Four of those operations were done laparoscopically. Only one patient developed grade A PF. No other postoperative complications were noticed. The mean length of stay was 5.4 days. The CLASP technique was applicable in both laparoscopic and open distal pancreatectomy. The key points include mobilisation of the pancreatic body from the retroperitoneum and division of the parenchyma with energy device. The technique of pancreatic stump closure involves the isolation of the pancreatic duct (PD), application of a double ligaclip on the proximal duct, division of the PD and finally suturing of the pancreatic stump. The CLASP technique is an effective and safe alternative technique to the current traditional methods of pancreatic stump closure.

Trinational Study Exploring the Early Impact of the COVID-19 Pandemic on Organ Donation and Liver Transplantation at National and Unit Levels.

BACKGROUND: The coronavirus disease (COVID-19) pandemic is stressing healthcare services to an unprecedented extent. There is anecdotal evidence of reduction in organ donation and transplantation activity across the world. METHODS: The weekly organ donation and liver transplant numbers over a 3-month period (Feb 17, 2020, till May 17, 2020) for the United States, United Kingdom, and India were compared with their previous year's activity. Liver transplant activity in 6 centers from these countries with varying local COVID-19 caseload was also compared. RESULTS: The COVID-19 pandemic has led to a significant contraction in organ donation and liver transplantation in all 3 countries. Peak reduction ranged from 25% in the United States to over 80% in the United Kingdom and India. The reduction was different for deceased donor and living donor liver transplantation and varied between centers within a country. There was early evidence of recovery of deceased donation in the United States and United Kingdom and resumption of living donor liver transplantation activity in India toward the end of the study period. A number of policy changes were undertaken at national and transplant center levels to ensure safe transplantation despite significant redirection of resources to combat the pandemic. CONCLUSIONS: There was a substantial reduction in organ donation and liver transplantation activity across the 3 countries with signs of recovery toward the end of the study period. Multiple factors including COVID-19 severity, stress on resources and influence of regulatory agencies and local factors are responsible for the reduction and recovery.

The role of neoadjuvant chemotherapy or chemoradiotherapy for advanced gallbladder cancer - A systematic review.

BACKGROUND: Neoadjuvant chemotherapy for advanced gallbladder cancer (GBC) has recently been proposed as an alternative to adjuvant chemotherapy, with potential increase in resectability rate and overall survival. AIM: To undertake a systematic review and critical appraisal of available literature on the use of neoadjuvant chemotherapy (NACT) or chemoradiotherapy (NACRT) in the treatment of advanced GBC. METHODS: Systematic review carried out in line with the Meta-analysis Of Observational Studies in Epidemiology guidelines. Primary outcomes were clinical benefit rate (CBR) of neoadjuvant therapy, defined as percentage of complete response, partial response and stable disease, resectability rate and R0 resection. Secondary outcomes were overall and disease-free survival. RESULTS: 8 studies met the inclusion criteria (n = 474), of which 398 (84.0%) received NACT and 76 (16.0%) received NACRT. 133 of 434 patients (30.6%) had progressive disease despite NACT or NACRT. The CBR was 66.6%. 17% of the patients who responded to chemotherapy did not proceed to surgery. 50.4% of the patients were considered suitable for surgical resection, of which 191 (40.3%) underwent curative resection. The R0 rate for the whole cohort was 35.4%. Overall survival ranged from 18.5 to 50.1 months for those who underwent curative resection versus 5.0-10.8 months for non-resected group. CONCLUSIONS: There is insufficient data to support the routine use of NACT or NACRT in advanced GBC, as this has only benefited a third of whole cohort, who eventually achieved a R0 resection. Future studies should be in the form of randomized controlled trials to investigate the role of neoadjuvant therapy in advanced GBC.

Papillary adenoma of the distal common bile duct associated with a synchronous carcinoma of the peri-ampullary duodenum.

CONTEXT: Benign tumours of the biliary tract are an extremely rare group of neoplasms. The diagnosis of these rare tumours is established on histopathological analysis following resection. Coincidence of a biliary adenoma of the distal common bile duct and a synchronous adenocarcinoma of the peri-ampullary duodenum has never been reported in the literature. CASE REPORT: We report a case of a papillary adenoma in the common bile duct in a 75-year-old female, who had synchronous invasive adenocarcinoma of the peri-ampullary duodenum. CONCLUSION: Isolated papillary adenoma of the bile duct is extremely rare, and in this unusual case it coincided with a peri-ampullary duodenal adenocarcinoma. However, this is a rare instance of an incidental finding within the distal bile duct following pancreaticoduodenectomy for curative treatment of a peri-ampullary adenocarcinoma.

Results following surgical resection for malignant pancreatic neuroendocrine tumours. A single institutional experience.

OBJECTIVE: The aim of the study was to present clinical outcomes of patients with malignant pancreatic neuroendocrine tumours (NET) following surgical resection with curative intent. Clinical and pathological factors that influenced the outcomes were also analysed. DESIGN: Retrospective case note study. PATIENTS: All patients with pancreatic NET that underwent surgery over a 7-year period (1999-2006). RESULTS: Twelve patients were identified with a median age at diagnosis of 54 years (range: 24-79 years). Common presenting symptoms include abdominal pain (n=8) and weight loss (n=3). Overall morbidity was 25% with one post-operative death. The median follow-up period was 41 months (range: 9-156 months). The overall 2- and 5-year actuarial survival rates were 88% and 70%, respectively. The overall survival was better in patients treated with surgery compared to patients managed medically (P<0.001). The disease-free survival rates were 62% at 2 and 5 years, respectively. Recurrent disease occurred in four patients and the median disease-free interval was 6 months (range: 3-14 months). On univariate analysis, angio-invasion (P=0.015) and degree of differentiation (P=0.024) were associated with developing recurrent disease. CONCLUSION: Surgical resection of malignant pancreatic NET results in good long-term survival in selected patients.

Ampullary carcinoma associated with an annular pancreas.

CONTEXT: Annular pancreas is an uncommon congenital abnormality. Co-existence of this condition with a pancreaticobiliary malignancy is an exceptionally rare occurrence. CASE REPORT: We present a case report of a 78-year-old woman with jaundice due to an ampullary carcinoma associated with an annular pancreas treated by pancreaticoduodenectomy. CONCLUSIONS: A collection of previously reported cases is reviewed together with the relevant literature. Obstructive jaundice is an uncommon feature of annular pancreas; hence the possibility of co-existent pancreaticobiliary malignancy should be excluded.

Pancreatic and peripancreatic tuberculosis mimicking malignancy.

CONTEXT: There are a variety of differential diagnoses for an abnormal mass arising from the pancreas of which isolated pancreatic or peripancreatic tuberculosis is an extremely rare diagnosis with a variety of elusive presentations. CASE REPORT: We report such a case which masqueraded as malignancy in 43-year-old man presenting with jaundice, weight loss and new onset diabetes. CONCLUSIONS: Tuberculosis should be considered as a differential diagnosis to an obscure pancreatic mass which may result in local complications amenable to surgery.

Total laparoscopic pancreaticoduodenectomy and reconstruction for a cholangiocarcinoma of the bile duct.

BACKGROUND: In this paper, we report on our experience with a totally laparoscopic pancreatico-duodenectomy performed for a cholangiocarcinoma of the lower third of the bile duct. METHODS: The patient was placed in the steep reverse Trendelenberg, Lloyd-Davis position. The procedure was performed with six laparoscopic ports, using similar steps to the open approach, with the use of an ultrasonic cutting and coagulating instrument for dissection and endoscopic linear stapling devices for the bile duct, intestinal, and gastroduodenal artery division. Reconstruction was done on a single loop by an intracorporeally sutured pancreaticojejunostomy, hepaticojejunostomy, and a stapled gastroenterostomy. The resection specimen was placed in a bag and retrieved through a 5-cm Pfannenstiel incision. RESULTS: Histology confirmed a T3 N1 R0 cholangiocarcinoma with the involvement of 1 of 17 lymph nodes. Twelve months following surgery, he remains well, having completed a course of adjuvant chemotherapy. CONCLUSIONS: Although the operation was technically demanding, it can be safely performed with a good oncologic result.

Outcomes after major hepatectomy in elderly patients.

BACKGROUND: We aimed to study the early and longterm outcomes of patients 70 years and older undergoing major liver resections, and compare the results with patients below the age of 70 years. STUDY DESIGN: All patients undergoing major liver resection (defined as three segments or more) from January 1993 to June 2004 were included. Patients were studied in two groups: 70 years of age and older (group E, elderly) and less than 70 years old (group Y, young). Early outcomes and longterm survival were analyzed. RESULTS: A total of 517 patients underwent major liver resection: group E, n=127; group Y, n=390 patients. There was no difference in operative mortality (group E, 7.9%; group Y, 5.4%; p=0.32) or postoperative morbidity (p=0.22) between the groups. Overall and disease-free survivals were not notably different for all patients (59% versus 57%, p=0.89; 60% versus 55%, p=0.28, respectively) or for a subgroup of patients with colorectal liver metastases (61% versus 55%, p=0.76; 60% versus 47%, p=0.07) in groups E versus Y, respectively. In multivariable analysis, American Society of Anesthesiologists grade 3 (p=0.024, hazard ratio [HR]=1.59, versus grade 1, 95% CI=1.06 to 2.39) and intraoperative transfusion>3 U (p<0.0005, HR=2.56, 95% CI=1.84 to 3.56) were predictors for overall survival. More than three tumors (p=0.025, HR=1.41, 95% CI=1.04 to 1.90) and redo resection (p=0.001, HR=2.80, 95% CI=1.51 to 5.19) were predictors of disease-free survival. CONCLUSIONS: Major liver resections can be safely performed in patients 70 years of age or older, with early results and survival similar to those in the younger than 70 age group. American Society of Anesthesiologists grade 3 and intraoperative transfusions>3 U were predictors for overall survival, and more than three tumors and redo resection were predictors for disease-free survival.
