The effects of Share 35 on the cost of liver transplantation.

On June 18, 2013, the United Network for Organ Sharing (UNOS) instituted a change in the liver transplant allocation policy known as "Share 35." The goal was to decrease waitlist mortality by increasing regional sharing of livers for patients with a model for end-stage liver disease (MELD) score of 35 or above. Several studies have shown Share 35 successful in reducing waitlist mortality, particularly in patients with high MELD. However, the MELD score at transplant has increased, resulting in sicker patients, more complications, and longer hospital stays. Our study aimed to explore factors, along with Share 35, that may affect the cost of liver transplantation. Our results show Share 35 has come with significantly increased cost to transplant centers across the nation, particularly in regions 2, 5, 10, and 11. Region 5 was the only region with a median MELD above 35 at transplant, and cost was significantly higher than other regions. Several other recipient factors had changes with Share 35 that may significantly affect the cost of liver transplant. While access to transplantation for the sickest patients has improved, it has come at a cost and regional disparities remain. Financial implications with proposed allocation system changes must be considered.

Kidney clamp, perfuse, re-implant: a useful technique for graft salvage after vascular complications during kidney transplantation.

Although intra-operative vascular complications during renal transplantation are rare, injuries associated with prolonged ischemia may lead to graft threatening early and late complications. This series describes a novel technique for intra-operative repair of vascular complications in five patients over a three-yr period. The method consists of rapid graft nephrectomy and re-preservation of the graft with cold University of Wisconsin solution, which allows for controlled/precise back table repair of the vascular injury without incurring prolonged warm ischemia time. In three cases, the donor renal vein (2) and donor renal artery (1) were damaged and required back table reconstruction. In two cases, the recipient iliac artery needed reconstruction. Three of the five cases used deceased donor iliac vessels from another donor for reconstruction. Two patients required postoperative dialysis for delayed graft function for three to nine d (average six d) and two patients had slow graft function. All grafts were functioning at 17 months (mean) after transplant, with a median serum of 1.61 mg/dL (0.74-3.69). This series demonstrates the effectiveness of kidney clamp, perfuse, resuscitate as an effective intra-operative technique to salvage grafts after vascular injury. Although the grafts may suffer from delayed or slow graft function, excellent long-term function is attainable.

ECD kidney transplantation outcomes are improved when matching donors to recipients using a novel creatinine clearance match ratio (CCMR).

Improved outcomes have been associated with various methods of size matching between expanded criteria (ECD) donors and recipients. A novel method for improved functional based matching was developed utilizing manipulation of Cockcroft-Gault estimated creatinine clearances for donor and recipient. We hypothesized that optimal clearance-based matches would have superior outcomes for both immediate graft function and long-term graft survival. For the analysis, recipients of ECD kidneys in the Scientific Registry of Transplant Recipients (SRTR) transplanted between October 1, 1987 and August 31, 2011 were included. Univariate and multivariate analyses predicted the hazard ratio of graft failure and the odds ratio of requiring dialysis within the first week. A total of 25,640 ECD kidney transplants were analyzed. On multivariate analysis, higher creatinine clearance match ratio (CCMR) was associated with increased graft failure and odds of requiring dialysis within the first week (comparing highest ratio quintile versus lowest ratio quintile: HR 1.43, p < 0.001; OR 2.08, p < 0.001). This study suggests that ECD kidneys have improved outcomes when the recipient/donor CCMR is optimized.

Reasons for COVID-19 Vaccine Hesitancy Among Patients Listed for Solid Organ Transplants.

BACKGROUND: Patients listed for solid organ transplants (LSOTP) are at high risk for severe COVID-19 outcomes. Despite national guidelines recommending COVID-19 vaccination for LSOTP, vaccine hesitancy and underuse are reported in this population; however, reasons for this finding have not been examined thoroughly. METHODS: This single-center retrospective survey analysis aimed to characterize reasons for COVID-19 vaccine hesitancy among 110 heart, liver, and kidney patients LSOTP who had not received all the recommended vaccine doses at the time of the study. Survey questions also investigated experiences with influenza vaccination. RESULTS: Fifty-four patients (49.1%) responded to the telephone survey. The most common reasons for vaccine hesitancy were perceived lack of research in vaccine development (31%), fear of vaccine-related side effects (22%), and belief that the vaccine was unnecessary (20%). Of the respondents, 35% reported changing their vaccine perception after being listed for a transplant, most commonly attributing this to a perception that the COVID-19 vaccine is not safe for transplant recipients (32%). Gender differences in hesitancy reasons were observed, with males more likely to delay vaccination until after transplantation, although this difference was not significant (P = .07). Despite these findings, 54% of all respondents reported receiving annual influenza vaccines consistently. CONCLUSION: Despite their risk, patients LSOTP show significant hesitancy toward COVID-19 vaccines owing to perceived safety and necessity issues. The results of this study can inform targeted educational efforts to address and rectify misconceptions and concerns about COVID-19 vaccination among patients LSOTP. Future studies focused on larger, more diverse cohorts are needed to expand our understanding of and address vaccination hesitancy among this vulnerable patient population.

Call me Ishmael: addressing the white whale of team communication in the operating room with labelled surgical caps at an academic medical centre.

INTRODUCTION: Effective communication in the operating room (OR) is crucial. Addressing a colleague by their name is respectful, humanising, entrusting and associated with improved clinical outcomes. We aimed to enhance team communication in the perioperative environment by offering personalised surgical caps labelled with name and provider role to all OR team members at a large academic medical centre. MATERIALS AND METHODS: This was a quasi-experimental, uncontrolled, before-and-after quality improvement study. A survey regarding perceptions of team communication, knowledge of names and roles, communication barriers, and culture was administered before and after cap delivery. Survey results were measured on a 5-point Likert Scale; descriptive statistics and mean scores were compared. All cause National Surgical Quality Improvement Project (NSQIP) morbidity and mortality outcomes for surgical specialties were examined. RESULTS: 1420 caps were delivered across the institution. Mean survey scores increased for knowing the names and roles of providers around the OR, feeling that people know my name and feeling comfortable communicating without barriers across disciplines. The mean score for team communication around the OR is excellent was unchanged. The highest score both before and after was knowing the name of an interdisciplinary team member is important for patient care. A total of 383 and 212 providers participated in the study before and after cap delivery, respectively. Participants agreed or strongly agreed that labelled surgical caps made it easier to talk to colleagues (64.9%) while improving communication (66.0%), team culture (60.5%) and patient care (56.8%). No significant differences were noted in NSQIP outcomes. CONCLUSIONS: Personalised labelled surgical caps are a simple, inexpensive tool that demonstrates promise in improving perioperative team communication. Creating highly reliable surgical teams with optimal communication channels requires a multifaceted approach with engaged leadership, empowered front-line providers and an institutional commitment to continuous process improvement.

Endoscopic treatment of anastomotic biliary strictures after living donor liver transplantation: outcomes after maximal stent therapy.

BACKGROUND: Living-donor liver transplantation (LDLT) has emerged as a viable strategy in an era of organ shortage. However, biliary strictures are a common complication of LDLT, and these strictures frequently require surgical revision after unsuccessful endoscopic therapy. The optimal endoscopic treatment for anastomotic biliary strictures (ABSs) after LDLT is undefined. OBJECTIVE: To determine the outcome of an aggressive endoscopic approach to ABSs after LDLT that uses endoscopic dilation followed by maximal stent placement. DESIGN: A retrospective study. SETTING: A tertiary-care academic medical center. PATIENTS: Forty-one patients with a diagnosis of ABS. INTERVENTIONS: Endoscopic retrograde cholangiography with balloon dilation and maximal stenting. MAIN OUTCOME MEASUREMENTS: Stricture resolution, stricture recurrence, and complication rates. RESULTS: Of 110 LDLTs completed, a biliary stricture developed after transplantation in 41 (37.3%), which included 38 patients with duct-to-duct anastomosis. The median (interquartile range [IQR]) follow-up time is 74.2 (2.5-120.8) months. Among them, 23 (60.5%) were male, and 20 (52.6%) had bile leakage associated with ABSs. The median time (IQR) to the development of an ABS after LDLT was 2.1 (1.2-4.1) months. Endoscopic retrograde cholangiography was attempted as initial therapy in all patients: 32 were managed entirely by endoscopic therapy, and 6 required initial percutaneous transhepatic cholangiography (PTC) to cross the biliary stricture, with endoscopic therapy performed thereafter. A median (IQR) of 4.0 (3.0-5.3) endoscopic interventions and 7.0 (4.0-10.3) stents were required to resolve the stricture. The time from the first intervention to stricture resolution was 5.3 (range 3.8-8.9) months. Biochemical markers including aspartate transaminase (76 vs 39 U/L, P = .001), alanine transaminase (127.5 vs 45.5 U/L, P < .001), alkaline phosphatase (590 vs 260 IU/L, P < .001), and total bilirubin (2.57 vs 1.73 mg/dL, P = .017) significantly improved after intervention. Recurrent stricture was observed after initial treatment in 8 (21%) patients. All recurrences were successfully re-treated endoscopically. All patients have been managed without surgical revision or retransplantation, resulting in 100% success by an intention-to-treat analysis. LIMITATIONS: Retrospective study, small sample size. CONCLUSIONS: In this series, aggressive endoscopy-based treatment with maximal stent placement strategy allows 100% resolution of all duct-to-duct ABSs after LDLT without the need for surgical intervention or retransplantation.

Acute Fulminant Hepatic Failure in 23-Year-Old Female Taking Homeopathic Remedy.

Homeopathic remedies made primarily from eggshells, and therefore calcium, can be marketed for treatment of back pain and vaginal discharge. We present a case of a 23-year-old otherwise healthy woman who presented with acute liver failure (ALF) ultimately requiring liver transplantation as a result of taking increased doses of a homeopathic product with the primary ingredient of eggshells. Although relatively uncommon compared with medications such as acetaminophen, herbal supplements have been reported to cause drug-induced liver injury (DILI), thought to be primarily due to contaminants. This is the first known report of DILI resulting from a homeopathic product with the primary ingredient of eggshells, and it demonstrates the importance of early ALF recognition and treatment, as well as the importance of practicing caution when using homeopathic supplements.

Case Bias Case Basis: Expanding Morbidity and Mortality Conference to Examine the Impact of Disparities in Surgical Care.

INTRODUCTION: Originally designed as a forum to discuss adverse patient events, Surgery Morbidity & Mortality Conference (M&M) has evolved into an integral tool within surgical education where trainees at all levels are taught to critically examine decision-making. Others have expanded the scope of subsets of M&M conferences to include additional factors that influence patient outcomes, such as social determinants of health, implicit bias and structural policies that contribute to health disparities. In this study, we implemented a disparities-based discussion into our surgical department's weekly M&M conference and examined the effect(s) on participants' understanding and perceptions of key disparities in access to surgical care. METHODS: An anonymous electronic survey was sent to attendees of the Department of Surgery's M&M conference including faculty, residents and medical students prior to implementation of the intervention. The survey queried perceptions of the presence and impact of disparities in access to surgical care and how these are addressed at the study institution. The standard presenter slide template was updated to include a "Disparities Factors" section within the "Reasons for Complication" slide. After over 1 year, a postintervention survey was sent to conference attendees that included the same questions as the initial survey, as well as new questions related to the intervention. Descriptive statistics were performed on survey results, and comparisons were made for paired pre-post items. RESULTS: Eighty conference attendees completed the pre-intervention survey, and 70 completed the postintervention survey (22 [27.5%]; 22 [31.4%] attendings, 24 [30.0%]; 21 [30.0%] residents, 34 [42.5%]; 27 [38.6%] medical students respectively). Socioeconomics and language were most commonly identified both pre- and postintervention as the most important factors contributing to disparities in care experienced by patients at the study institution. Respondents agreed disparities in access significantly impact surgical care, and there was an increase in the number of respondents who reported feeling that disparities are being addressed postintervention. A total of 69% (n = 48) of respondents thought that integrating discussion of disparities in access to surgical care into M&M improved their understanding of the role these disparities play, 66% (n = 46) felt that their own thinking or practice changed regarding patient disparities, 84% (n = 59) reported integrating these discussions of disparities into M&M has been helpful overall. CONCLUSION: The inclusion of a disparities discussion in weekly M&M conference has led to positive change at the study institution, fostering a more comprehensive and socially conscious dialogue within the Department of Surgery. Survey respondents agreed that disparities exist in access to surgical care, and that the intervention improved their perceptions of how the study institution addresses disparities. Respondents felt that the integration of a disparities discussion was overall helpful, improved their knowledge of disparities in access to surgical care, and impacted their plans to address disparities in their own practices.

Surgical pit crew: initiative to optimise measurement and accountability for operating room turnover time.

BACKGROUND AND OBJECTIVES: Turnover time (TOT), defined as the time between surgical cases in the same operating room (OR), is often perceived to be lengthy without clear cause. With the aim of optimising and standardising OR turnover processes and decreasing TOT, we developed an innovative and staff-interactive TOT measurement method. METHODS: We divided TOT into task-based segments and created buttons on the electronic health record (EHR) default prelogin screen for appropriate staff workflows to collect more granular data. We created submeasures, including 'clean-up start', 'clean-up complete', 'set-up start' and 'room ready for patient', to calculate environmental services (EVS) response time, EVS cleaning time, room set-up response time, room set-up time and time to room accordingly. RESULTS: Since developing and implementing these workflows, measures have demonstrated excellent staff adoption. Median times of EVS response and cleaning have decreased significantly at our main hospital ORs and ambulatory surgery centre. CONCLUSION: OR delays are costly to hospital systems. TOT, in particular, has been recognised as a potential dissatisfier and cause of delay in the perioperative environment. Viewing TOT as one finite entity and not a series of necessary tasks by a variety of team members limits the possibility of critical assessment and improvement. By dividing the measurement of TOT into respective segments necessary to transition the room at the completion of one case to the onset of another, valuable insight was gained into the causes associated with turnover delays, which increased awareness and improved accountability of staff members to complete assigned tasks efficiently.

Early patient and liver allograft outcomes from donation after circulatory death donors using thoracoabdominal normothermic regional: a multi-center observational experience.

Background: Donation after circulatory death (DCD) liver allografts are associated with higher rates of primary non-function (PNF) and ischemic cholangiopathy (IC). Advanced recovery techniques, including thoracoabdominal normothermic regional perfusion (TA-NRP), may improve organ utilization and patient and allograft outcomes. Given the increasing US experience with TA-NRP DCD recovery, we evaluated outcomes of DCD liver allografts transplanted after TA-NRP. Methods: Liver allografts transplanted from DCD donors after TA-NRP were identified from 5/1/2021 to 1/31/2022 across 8 centers. Donor data included demographics, functional warm ischemic time (fWIT), total warm ischemia time (tWIT) and total time on TA-NRP. Recipient data included demographics, model of end stage liver disease (MELD) score, etiology of liver disease, PNF, cold ischemic time (CIT), liver function tests, intensive care unit (ICU) and hospital length of stay (LOS), post-operative transplant related complications. Results: The donors' median age was 32 years old and median BMI was 27.4. Median fWIT was 20.5 min; fWIT exceeded 30 min in two donors. Median time to initiation of TA-NRP was 4 min and median time on bypass was 66 min. The median recipient listed MELD and MELD at transplant were 22 and 21, respectively. Median allograft CIT was 292 min. The median length of follow up was 257 days. Median ICU and hospital LOS were 2 and 7 days, respectively. Three recipients required management of anastomotic biliary strictures. No patients demonstrated IC, PNF or required re-transplantation. Conclusion: Liver allografts from TA-NRP DCD donors demonstrated good early allograft and recipient outcomes.

Laparoscopic bilateral native nephrectomies with simultaneous kidney transplantation.

UNLABELLED: Study Type--Therapy (case series) Level of Evidence 4. What's known on the subject? and What does the study add? Extirpation of polycystic kidneys for various medical reasons has been performed using many different approaches in attempts to limit morbidity from such a large operation. In indicated patients, it has usually been offered in a staged approach with renal transplantation to avoid graft complications. We published the first case of simultaneous laparoscopic bilateral native nephrectomy with kidney transplant in 2008. The present study shows our continued experience with offering this minimally invasive, single surgery alternative. The results are comparable to a staged laparoscopic approach with significantly shorter total hospital stay and one recovery for the patient and his/her family. OBJECTIVE: • To analyse the perioperative outcomes of native bilateral laparoscopic nephrectomy (BLN) with simultaneous kidney transplantation. PATIENTS AND METHODS: • From November 2000 to April 2011, 37 patients were seen for renal failure secondary to autosomal-dominant polycystic kidney disease (ADPKD) and underwent renal transplant with native nephrectomies at a single tertiary academic centre. • In all, 15 patients underwent BLN for ADPKD followed by simultaneous kidney transplantation. • The other 22 patients underwent BLN for ADPKD with kidney transplant performed at a separate setting. • Demographic data, perioperative outcomes, complications regardless of need for intervention, and graft function were analysed in both groups. RESULTS: • The combined surgery was completed without intraoperative complication in all cases. • The median total operative duration was 372 min, estimated blood loss was 300 mL with two patients requiring transfusion, and the median (range) hospital stay was 5 (3-7) days. • All patients had immediate graft function with additional relief of compressive symptoms. • In comparison to our staged cohort, the simultaneous group had a significantly shorter total hospital stay. • All other outcomes and complication rates were comparable. CONCLUSION: • In ADPKD, a less invasive laparoscopic approach for native nephrectomies with simultaneous renal transplant offers comparable morbidity without graft compromise and the convenience of one operation and one recovery for the patient.

A Novel Fellowship in Perioperative Administration, Quality and Informatics: A Pilot Experience for Training Surgical Leaders.

Value-based, outcome-oriented care supported with innovative technology is the future of surgery. We established a novel fellowship in Perioperative Administration, Quality, and Informatics. The aim is to equip future surgeon scholars with the requisite knowledge base and skillset to serve as institutional leaders capable of transforming surgical healthcare delivery. The model was designed as a project-based, "operations-focused" education with supplemental didactics and mentored by surgical leaders and institutional executives. We describe our initial experience, successes, and challenges such that a similar model may be replicated elsewhere.

Understanding the Impact of Pneumonia and Other Complications in Elderly Liver Transplant Recipients: An Analysis of NSQIP Transplant.

Despite an increasing demand for liver transplantation in older patients, our understanding of posttransplant outcomes in older recipients is limited to basic recipient and graft survival. Using National Surgical Quality Improvement Program Transplant, we tracked early outcomes after liver transplantation for patients >65. METHODS: We conducted a retrospective analysis of patients in National Surgical Quality Improvement Program Transplant between March 1, 2017 and March 31, 2019. Recipients were followed for 1 y after transplant with follow-up at 30, 90, and 365 d. Data were prospectively gathered using standard definitions across all sites. RESULTS: One thousand seven hundred thirty-one adult liver transplants were enrolled; 387 (22.4%) were >65 y old. The majority of older recipients were transplanted for hepatocellular carcinoma. The older cohort had a lower lab Model for End-Stage Liver Disease and was less likely to be hospitalized at time of transplant. Overall, older recipients had higher rates of pneumonia but no difference in intensive care unit length of stay (LOS), total LOS, surgical site infection, or 30-d readmission. Subgroup analysis of patients with poor functional status revealed a significant difference in intensive care unit and total LOS. Pneumonia was even more common in older patients and had a significant impact on overall survival. CONCLUSIONS: By targeting patients with hepatocellular carcinoma and lower Model for End-Stage Liver Diseases, transplant centers can achieve nearly equivalent outcomes in older recipients. However, older recipients with poor functional status require greater resources and are more likely to develop pneumonia. Pneumonia was strongly associated with posttransplant survival and represents an opportunity for improvement. By truly understanding the outcomes of elderly and frail recipients, transplant centers can improve outcomes for these higher-risk recipients.

Six-minute walk distance predicts mortality in liver transplant candidates.

The 6-minute walk distance (6MWD) is a simple test measuring global physical function. It is commonly used to predict mortality in patients with cardiac and pulmonary diseases, but it is also useful in assessing the functional status of patients with a variety of other medical conditions. We sought to determine (1) the characteristics of the 6MWD in patients listed for liver transplantation (LT), (2) the existence of a relationship between the 6MWD and the quality of life, and (3) the relationship between the 6MWD and survival in LT candidates. The 6MWD was prospectively measured in all patients listed for LT. The 6MWD was determined when the listed Model for End-Stage Liver Disease (MELD) score was ≥ 15. Patients were followed until LT, death, removal from the wait list, or the end of the study period. Quality of life was assessed with the Short Form 36 (SF-36). In 121 patients, the mean 6MWD was 369 ± 122 m; it was not related to age, height, weight, body mass index, albumin level, or etiology of liver disease and showed a moderate correlation with the physical component score (PCS) on the SF-36 (r = 0.4) and a moderate inverse correlation with the native MELD score (r = -0.61). In an unadjusted analysis, a high native MELD score, a low 6MWD, and a low PCS were associated with mortality, with only the 6MWD retaining significance after adjustment for covariates. Each 100-m increase in the 6MWD was significantly associated with increased survival (hazard ratio = 0.48, P = 0.0001), with 6MWD < 250 m being associated with an increased risk of death (P = 0.0001). In conclusion, the 6MWD is significantly reduced in patients awaiting LT and is inversely correlated with the native MELD score. A pretransplant 6MWD < 250 m is a risk for death on the wait list.

Living donor liver transplantation in polycystic liver disease.

In the current Model for End-Stage Liver Disease system, patients with polycystic liver disease (PCLD) who have a poor quality of life secondary to their massive hepatomegaly are no longer competitive for a deceased donor liver transplant if their liver function is well preserved. Traditionally, a caval resection has been advocated in these patients because of the difficulty of the hepatectomy with hepatomegaly, which makes living donation impossible. This series looks at 3 patients who underwent a caval sparing hepatectomy and subsequent living donor liver transplantation (LDLT) for PCLD. Graft and patient survival was 100%, and there were few complications in either donors or recipients. LDLT is an ideal option for patients with PCLD and preserved liver function but poor quality of life.

Laparoscopic and hand-assisted distal pancreatectomy.

With the increased use of CT, discovering incidental pancreatic lesions has become commonplace. Lesions in the distal pancreas lend themselves well to laparoscopic resection. We reviewed our experience with laparoscopic distal pancreatectomy. During the study period, 32 distal pancreatectomies were performed. There were 20 females. Mean patient age was 58.0 years (range, 23-83 years) and mean body mass index was 29.9 Kg/m2 (range, 19.9-44.7 Kg/m2). Technique was laparoscopic (25) or hand-assisted (seven) with one conversion in each group. The spleen was preserved in six patients (18.8%). Mean operative time overall was 238 minutes (range, 140-515 minutes); hand-assisted was 222 minutes and laparoscopic was 254 minutes. Estimated blood loss averaged 221 mL (range, 50-1800 mL). Mean tumor size was 2.7 cm (range, 0.6-7 cm). Tumor pathology was serous cystadenoma (10), neuroendocrine tumor (six), mucinous cystic neoplasm (four), intrapapillary mucinous neoplasm (four), adenocarcinoma (three), other (four), and solid pseudopapillary neoplasm (one). Mean length of stay was 5 days (range, 3-11 days). Complications were pancreatic fistula (six), wound infection (two), pulmonary embolism (one), pancreatitis (one), myocardial infarction (one), postoperative bleed from combined laparoscopic bilateral oophorectomy (one), and pancreatic stump staple line bleed requiring reoperation (one). There were no perioperative deaths. All pancreatic fistulas resolved with conservative management.

Combined resection of the liver and the inferior vena cava for hydatid disease.

Hydatid disease can result in cystic liver disease. If a conservative treatment fails, these cysts require resection. Involvement of the inferior vena cava requiring resection for hydatid disease is unusual. We present a case of hydatid disease with complete caval obstruction and resultant portal hypertension that required combined liver resection and inferior vena cava replacement.

Surgical management of gallbladder carcinoma: a review.

Gallbladder cancer is a relatively unusual, but often lethal malignancy. Surgical management has historically been palliative only; however, with the advancement of techniques in hepatobiliary surgery, varying extents of surgical intervention have been advocated for cure. This article reviews the current approach to the surgical management of gallbladder cancer and discusses the rationale for an aggressive approach to this disease.

Portal vein resection for hilar cholangiocarcinoma.

Hilar cholangiocarcinoma remains a difficult challenge for the surgeon. Achieving negative surgical margins when resecting this relatively uncommon tumor is technically demanding as a result of the close proximity of the bile duct bifurcation to the vascular inflow of the liver. A recent advance in surgical treatment is the addition of portal vein resection to the procedure. Resection of the portal vein increases the number of patients offered a potentially curative approach but is technically more difficult and may increase the risk of the procedure. This study reviews the results of portal vein resection for hilar cholangiocarcinoma. Between 1998 and 2005, 60 patients underwent potentially curative resections of hilar cholangiocarcinoma. Mean patient age was 64 +/- 12 years (range, 24-85 years). Liver resections performed along with biliary resection included 49 trisegmentectomies (37 right, 12 left) and 10 lobectomies (8 left, 2 right). One patient had only the bile duct resected. Four patients also had simultaneous pancreaticoduodenectomy performed. Twenty-six patients required portal vein resection and reconstruction to achieve negative margins, 3 of which also required reconstruction of the hepatic artery. Operative mortality was 8 per cent with an overall complication rate of 40 per cent. Patients who underwent portal vein resection had an operative mortality of 4 per cent, which was not different from the 12 per cent mortality in patients who did not undergo portal vein resection (P = 0.39). There was no difference in actuarial patient survival between patients who underwent portal vein resection and those who did not (5-year survival 39 per cent vs. 41 per cent, P = not significant). Negative margins were achieved in 80 per cent of cases and were associated with improved survival (P < 0.01). Five-year actuarial survival in patients undergoing resection with negative margins was 45 per cent. There was no difference in margin status or long-term survival between those patients who underwent portal vein resection and those who did not. Only negative margin status was associated with improved survival by multivariate analysis. Portal vein resection for hilar cholangiocarcinoma is safe and allows a chance for long-term survival in otherwise unresectable patients.
