Purpose: Bilateral native nephrectomies are needed in ESRD patients with select indications in a pre-transplant setting. Yet, the perioperative morbidity is significant in this population. Herein we evaluate the efficacy and utility of r-SABN., Method: A total of 12 patients were consented at a single center. Of 12 patients, 3 patients did not meet study criteria and were excluded. Preoperative, perioperative, and postoperative data were prospectively collected from 9 patients from electronic health records and administered postoperative surveys. Patients were assessed at 30-180 days postoperatively for follow-up., Results: Mean operative time was 204.3 ± 59.7 min (142.0-314.0) and estimated blood loss during operation was 94.4 ± 87.3 ml (25.0-300.0). The mean length of hospital stay was 2 ± 0.7 days (1-3) for all patients. Total post-operative opioid usage was normalized to morphine dose equivalents (MDE) and calculated to be 56.1 ± 30.4 mg (30.8-101.8). Patients experienced a fourfold and tenfold respective increase in weekly structural and incidental physical activity from 30 to 180 days postoperatively. There were no procedure related intraoperative or postoperative complications reported in the cohort., Conclusion: Overall, r-SABN afforded the patients low morbidity. Longitudinal studies are in progress to further assess the efficacy and outcome of this procedure. In a single-center study, we demonstrate r-SABN is viable and provides a novel tool for treatment of ESRD patients requiring this procedure., (© 2020.

Background: Small bowel obstructions (SBOs) are common following a large intra-abdominal operation; however, SBOs caused by bezoars are unreported in patients following liver-kidney transplantation procedures, particularly in adults., Case Summary: A 65-year-old Caucasian female presented with nausea and nonbilious emesis during her postoperative course following a simultaneous liver-kidney transplantation. She developed worsening nausea and vomiting with significant abdominal distension and obstipation. Computed tomography imaging showed a marked abnormal dilation of multiple small bowel loops with a distinct transition point that was suggestive of a small bowel obstruction. An exploratory laparotomy revealed a foreign body in the intestinal track approximately 30 cm from the ileocecal valve. The foreign body was extracted and identified as a bezoar with hair follicles and old digestive contents. Following the operation, the patient demonstrated rapid clinical improvement with resolution of nausea, emesis, and progress in bowel motility., Conclusion: SBOs caused by bezoars can occur immediately following a liver-kidney transplantation and should not be discounted as a diagnosis., Competing Interests: Conflict-of-interest statement: The author(s) have no conflict(s) of interest to disclose., (©The Author(s) 2020.

Purpose: In patients with loin pain hematuria syndrome (LPHS), a response to percutaneous renal hilar blockade (RHB) and a multidisciplinary team (MDT) evaluation predicts patient's potential renal auto-transplantation (RAT) success., Methods: A pain assessment was performed using a 0-10 numeric pain rating scale prior to a percutaneous RHB under CT guidance. If the pain score was reduced > 50% immediately after the RHB, patients were evaluated for RAT by a MDT. Pre-operative and 1-year post-operative quality-of-life surveys were administered to each RAT patient., Results: 43 LPHS patients were referred for RHB. Of the 38 patients who received a RHB, 31 had > 50% reduction in pain scores. Pre- and post-RHB mean pain scores were 6/10 and 0.7/10, respectively, in patients who had > 50% reduction in pain. 22 of the patients who responded favorably then proceeded to RAT. Twelve patients had at least 1-year follow-up after RAT. All patients had a meaningful decrease in their pain. Mean pain score at 1 year was 0.8/10 for an 85% overall reduction in pain. 92% of patients experienced a ≥ 50% reduction in pain at 1 year. Mean Beck Depression Inventory (BDI) score (0-66) 1 year after RAT decreased from 25.2 pre-op (moderate depression) to 12.8 post-op (minimal depression)., Conclusions: A MDT approach utilizing a RHB should be considered as a tool to select appropriate LPHS patients for RAT to achieve long-term success in reducing chronic pain and depression while increasing quality of life.

Opioid exposure is a concern after live donation for kidney transplant. We theorized that an enhanced recovery after surgery pathway (ERAS) using pregabalin preoperatively to desensitize nerves followed by the nonsteroidal anti-inflammatory drug ketorolac, during and after surgery, can control pain, thus requiring less perioperative narcotics. The aim of this study was to determine if the use of a nonopioid analgesic ERAS protocol for donor nephrectomies could decrease the use of narcotics without an increase in complications compared with standard of care (SOC). This is a single-center, prospective, double-blind, randomized clinical trial involving a total of 62 patients undergoing nephrectomy for live donor kidney transplant. Length of hospital stay (LOS) was significantly reduced by 10% in the ERAS group versus the SOC-plus-placebo group. Morphine dose equivalents were significantly reduced by 40% in the study group versus the SOC-plus-placebo group. The use of this nonopioid analgesic ERAS pathway for donor nephrectomies decreased the use of narcotics without an increase in complications compared with SOC. There was significantly reduced LOS and less narcotic use in the study group versus the SOC-plus-placebo group.

Background: Local hemostatic agents have a role in limiting bleeding complications associated with liver resection., Methods: In this randomized, phase III study, we compared the efficacy and safety of Fibrin Sealant Grifols (FS Grifols) with oxidized cellulose sheets (Surgicel®) as adjuncts to hemostasis during hepatic resections. The primary efficacy endpoint was the proportion of patients achieving hemostasis at target bleeding sites (TBS) within 4 min (T 4 ) of treatment application. Secondary efficacy variables were time to hemostasis (TTH) at a later time point if re-bleeding occurs and cumulative proportion of patients achieving hemostasis by time points T 2 , T 3 , T 5 , T 7 , and T 10 ., Results: The rate of hemostasis by T 4 was 92.8% in the FS Grifols group (n = 163) and 80.5% in the Surgicel® group (n = 162) (p = 0.01). The mean TTH was significantly shorter (p < 0.001) in the FS Grifols group (2.8 ± 0.14 vs. 3.8 ± 0.24 min). The rate of hemostasis by T 2 , T 5 , and T 7 was higher and statistically superior in the FS Grifols group compared to Surgicel®. No substantial differences in adverse events (AE) were noted between treatment groups. The most common AEs were procedural pain (36.2 vs. 37.7%), nausea (20.9 vs. 23.5%), and hypotension (14.1 vs 6.2%)., Conclusions: FS Grifols was safe and well tolerated as a local hemostatic agent during liver resection surgeries. Overall, data demonstrate that the hemostatic efficacy of FS Grifols is superior to Surgicel® and support the use of FS Grifols as an effective local hemostatic agent in these surgical procedures.

Biliary mucoceles after deceased donor liver transplantation are a rarity, and mucoceles mimicking a gallbladder from the recipient remnant cystic duct have not been described until this case. We describe a 48-year-old male who presented with right upper quadrant pain and was found to have a recipient cystic duct mucocele 3 mo after receiving a deceased donor liver transplant. We describe the clinical presentation, laboratory and imaging findings (including the appearance of a gallbladder), multidisciplinary approach and surgical resolution of this mucocele originating from the recipient cystic duct, and a review of the literature., Competing Interests: Conflict-of-interest statement: The authors declare that there is no conflict of interest regarding the publication of this article.

Aortorenal bypass is an effective and durable therapy for autoimmune-induced renovascular hypertension. However, when technical and patient factors preclude this option, renal autotransplantation can be a viable alternative. We present a 32-year-old woman who underwent aortobi-iliac bypass with left renal autotransplantation for malignant hypertension secondary to Takayasu arteritis. This is the first description of using machine preservation with a continuous pulsatile perfusion pump to maintain renal preservation before reimplantation. Our method proved safe to the patient and allowed for protection of the organ from prolonged warm ischemia and intraoperative hypoperfusion during a complex reconstruction., (Copyright © 2014 Elsevier Inc.

Cardiac surgery and liver transplantation (LT) are rarely performed at the same time, because of the potential risks of coupling two such complex surgical procedures [1-3]. This combined surgery is typically reserved for patients with structural heart disease, including multivessel obstructive coronary artery disease and severe valvular disease with heart failure and end-stage liver disease, in whom the untreated organ may decompensate if only one organ is addressed [4]. Combined aortic valve replacement (AVR) and LT is the rarest of such combined surgery, with only ten cases published previously. We present the first reported case of combined minimally invasive AVR and LT and review the literature on similar combined surgery.

Background: Involvement of the IVC has traditionally been considered a relative contraindication to resection for advanced tumors of the liver. Combined resection of the liver and IVC for malignancy can be performed safely and results in long-term survival in select patients., Study Design: Sixty patients undergoing hepatic and IVC resection by the primary author from 1996 to 2012 were reviewed. Median age was 52 years. Resections were carried out for cholangiocarcinoma (n = 26), hepatocellular carcinoma (n = 16), colorectal metastases (n = 13), gastrointestinal stromal tumor (n = 2), hepatoblastoma (n = 2), and squamous cell carcinoma (n = 1). Resections performed included 27 right and 5 left trisegmentectomies and 25 right and 3 left lobectomies, including the caudate lobe. Ex vivo procedures were performed in 6 patients using veno-venous bypass and the other 54 procedures were performed using varying degrees of vascular isolation. In situ cold perfusion of the liver was used in 8 patients. The IVC was reconstructed using a tube graft (n = 38) primarily (n = 8) or with patches (n = 14)., Results: There were 5 perioperative deaths (8%). Three patients died of liver failure, 1 patient died of pulmonary hemorrhage, and 1 patient died of massive pulmonary embolism. Nine patients had evidence of postoperative liver failure that resolved with supportive management. Three patients required temporary dialysis. With a median follow-up of 31 months, 14 patients have died of recurrent malignancy between 22 and 44 months, and an additional 4 patients are alive with disease at 16 to 33 months. Actuarial 1- and 5-year survival rates were 89% and 35%, respectively., Conclusions: Inferior vena cava involvement by malignancy does not obviate liver resection. The procedure's increased risk is balanced by the possible benefits, given the lack of alternative curative approaches., (Copyright © 2013 American College of Surgeons. Published by Elsevier Inc.

Purpose: Hepatitis C (HCV) is the most common liver disease in patients transplanted with hepatocellular carcinoma (HCC) in the West. We examined predictors of HCC recurrence in liver transplant recipients with HCV., Methods: From 1997 to 2006, 53 patients with HCC and HCV underwent liver transplantation. Pre-and post-operative data (including liver biopsies 4 months post-transplant) were collected. Differences between HCC recurrence and non-recurrence groups were detected by Student's t test or chi-square test. Data were analyzed as predictors of HCC recurrence by logistic regression multivariate analysis. Cumulative survival was analyzed by Kaplan-Meier curves and compared by the log-rank test., Results: Eleven of 53 patients (20.8%) developed HCC recurrence at a median interval of 15 months (2 to 55 months). Median Histology Activity Index (HAI) of liver biopsies, AST, and ALT at 4 months were significantly greater in patients with HCC recurrence. Independent predictors of HCC recurrence were HAI ≥ 4 at 4 months, ALT ≥ 100 at 4 months, and vascular invasion. Patients with HCC recurrence had significantly decreased survival., Conclusions: In this preliminary study, Histology Activity Index and ALT at 4 months, as well as vascular invasion, predicted HCC recurrence in liver transplant recipients with HCV.

Objectives: The benefit of a solid-organ transplant experience during general surgical training has been questioned recently. In 2008, in response to an American Board of Surgery (ABS) directive, a survey was conducted by the Association of Program Directors in Surgery (APDS) in coordination with the American Society of Transplant Surgeons (ASTS) to determine the perceived value of a transplant surgery rotation to program directors and residents. With the aim of providing additional insight, we conducted a separate study, independent of the ABS and ASTS, to ascertain resident perceptions regarding the specific skill sets that they acquire during their transplant surgery rotations and their applicability to other surgical subspecialties., Methods: A preliminary, 51-item, web-based questionnaire was completed by 69.6% of residents in nationally accredited general surgery programs who accessed the survey. The results were examined using appropriate statistical methods to determine associations between answers., Results: Although only 16.6% of participants responded that they were considering a career in transplantation, 63.4% answered that the skill sets acquired during this rotation would assist them in their surgical careers regardless of their chosen specialty. Most (65.5%) respondents answered that the techniques learned were directly applicable to other specialties, such as vascular, urologic, trauma, and hepatobiliary surgery. Free response questions indicated that the most common criticisms of this rotation were the limited amount of operative participation, lack of teaching by attendings, and lifestyle limitations., Conclusions: The results of this study indicate that surgery residents are conflicted regarding their transplant surgery experience but regard it as a beneficial addition to their training. Most respondents indicated also that these skills were transferable directly to other surgical specialties., (Copyright © 2012 Association of Program Directors in Surgery. Published by Elsevier Inc.

Current liver allocation policy in the United States grants liver transplant candidates with stage T2 hepatocellular carcinoma (HCC) a priority Model for End-Stage Liver Disease (MELD) score of 22, regardless of age. Because advanced age may portend an increase in all-cause mortality after transplantation for any diagnosis, the aim of this study was to examine overall posttransplant survival in elderly patients with HCC versus younger cohorts. Based on Organ Procurement and Transplantation Network data, Kaplan-Meier 5-year survival rates were compared. Recipients undergoing primary liver transplantation were stratified into cohorts based on age (<70 or ≥ 70 years) and the receipt of MELD exception points for HCC. Log-rank and Wilcoxon tests were used for statistical comparisons. In 2009, 143 transplants were performed for patients who were 70 years old or older. Forty-two percent of these patients received a MELD exception for HCC. Regardless of the diagnosis, the overall survival rate was significantly attenuated for the septuagenarians versus the younger cohort. After 5 years of follow-up, this disparity exceeded 10% to 15% depending on the populations being compared. The 1-, 2-, 3-, 4-, and 5-year actuarial survival rates were 88.4%, 83.2%, 79.6%, 76.1%, and 72.7%, respectively, for the patients who were younger than 70 years and 81.1%, 73.8%, 67.1%, 61.9%, and 55.2%, respectively, for the patients who were 70 years old or older. Five-year survival was negatively affected for patients with HCC who were younger than 70 years; this disparity was not observed for patients with HCC who were 70 years old or older. In conclusion, although patients who are 70 years old or older compose a small fraction of transplant recipients in the United States, patients in this group undergoing transplantation for HCC form an even smaller subset. Overall, transplantation in this age group yields outcomes inferior to those for younger cohorts. However, unlike patients who are less than 70 years old and receive MELD exception points, overall liver transplant survival is not affected by HCC at an advanced age., (Copyright © 2012 American Association for the Study of Liver Diseases.)

Background and Aims: The aim of this retrospective study is to assess the impact of calcineurin inhibitors on hepatitis C virus recurrence following liver transplantation., Methods: A total of 396 patients underwent liver transplantation for hepatitis C virus-induced liver disease between 1991 and 2005 at a single center. We examined the pre- and post-operative characteristics of patients who received either cyclosporine (n = 126) or tacrolimus (n = 270) as maintenance immunosuppression. In addition, we compared the postoperative course, including patient, graft and hepatitis C virus recurrence-free survival between the two groups., Results: There were no significant differences between the two groups in either post-operative hepatitis C virus-ribonucleic acid or histological fibrosis score (performed within 6 months after transplant per protocol). The graft and patient survivals did not differ between the two groups (logrank p = 0.34 and 0.15, respectively). Histologic hepatitis C virus recurrence-free survival, however, was significantly higher in the cyclosporine group than in the tacrolimus group (55.4 vs. 30.8% at 1 year, 18.6 vs. 10.3% at 3 years, 16.7 vs. 8.1% at 5 years, p < 0.001)., Conclusions: Patients transplanted for hepatitis C virus and treated with cyclosporine versus tacrolimus may have a higher recurrence-free survival.

Caroli's disease (including Caroli's syndrome) is a rare autosomal recessive disorder of the liver characterized by diffuse cystic dilatation of the intrahepatic bile ducts. The disease may present at any age and is characterized by recurrent episodes of biliary obstruction, cholangitis, hepaticolithiasis, and liver abscesses. Caroli's syndrome is further associated with congenital hepatic fibrosis and portal hypertension. Patients with recurrent complications or cirrhosis may die because of recurrent infection, portal hypertension, liver failure, or cholangiocarcinoma. Liver transplantation is the treatment of choice for these complicated patients. Here we describe the youngest reported patient with Caroli's syndrome treated successfully using liver transplantation and review the recent literature., (Copyright © 2011 Elsevier Inc.

Aim: The aim of this study is to clarify the association between hepatitis C virus (HCV) infection and post-transplant lymphoproliferative disease (PTLD) in the liver allograft., Methods: Of the 933 adults who underwent liver transplantation (LT) between 1990 and 2005, 10 patients developed PTLD. Seven of the 10 patients that were HCV(+) (group 1) were compared with three HCV-negative recipients (group 2)., Results: The mean time between LT and PTLD was 24.5 months. There were no differences between in Epstein-Barr virus antibody status or tumor lymphocyte subsets. In five of the seven HCV-positive recipients who developed PTLD, PTLD recurred preferentially in the liver allograft, whereas none of the three HCV-negative patients who developed PTLD did so in the liver (71.4 vs. 0%, respectively, P=0.038). In all five patients with graft PTLD, HCV recurred within 12 months followed by PTLD. There were significant differences between groups 1 and 2 in mean lymphocyte infiltrate scores (6.0±2.1 vs. 2.0±0.7, P=0.037), fibrosis stage (2.4±0.5 vs. 0.7±0.5, P=0.029), and frequency of lymphoid follicles in portal areas (33.6±14.8% vs. 1.1±2.3%, P=0.0002)., Conclusion: When PTLD occurs in patients with HCV recurrence after LT, it does so preferentially in the liver allograft.

Background: Vascular reconstruction along with major liver resection in the setting of liver dysfunction caused by biliary obstruction can be associated with increased risk. The purpose of this report is to assess the role of portal vein resection and reconstruction in the surgical management of hilar cholangiocarcinoma., Study Design: Ninety-five patients with hilar cholangiocarcinoma who underwent resection between 1999 and 2010 were reviewed. Liver resections performed along with biliary resection included 84 trisegmentectomies (63 right, 21 left) and 11 lobectomies (8 left, 3 right). Thirteen patients also had simultaneous pancreaticoduodenectomy performed. Forty-two patients underwent portal vein resection and reconstruction. Five patients required reconstruction of the hepatic artery. Preoperative portal vein embolization was used in 38 patients., Results: Patients undergoing resection had a 5% mortality rate, with an overall morbidity rate of 36%. Patients who underwent portal vein resection had perioperative mortality and morbidity similar to those who did not have portal vein resection. Median survival was 38 months (95% CI, 29-51 months), with a 5-year survival rate of 43%. There was no difference in long-term survival between those patients who had portal vein resection and those that did not. Negative margins were achieved in 84% of cases and were associated with improved survival (p < 0.01). Five-year survival rate in patients undergoing R0 resection was 50%. Patients with positive lymph nodes appeared to have a worse 5-year survival rate than patients with node-negative status (23% versus 49%); however, only negative margin status was associated with improved survival by multivariate analysis., Conclusions: Surgical resection of hilar cholangiocarcinoma that requires resection of the portal vein can be performed safely and should not be a contraindication to resection., (Copyright © 2011 American College of Surgeons.

Background: Combined resection of both the liver and pancreas for malignancy remains a controversial procedure. To many, the need for such an extended procedure implies an extent of disease that is usually not amenable to surgical control, and the extent of the procedure exposes the patients to substantial operative risks. The purpose of this study was to assess our results with combined resection of the liver and pancreas., Study Design: Forty patients underwent combined liver and pancreas resection from 1996 to 2009. Patient ages ranged from 39 to 69 years (mean 53 years). Underlying diagnoses were neuroendocrine tumor (13), cholangiocarcinoma (13), gallbladder carcinoma (9), gastrointestinal stromal tumor (3), colorectal cancer (1), and metastatic ocular melanoma (1). Pancreatic resections included 26 pancreaticoduodenectomies (PD) and 14 distal pancreatic resections. Liver resections included 18 trisectionectomies (13 right, 5 left), 10 lobectomies (8 right, 2 left), and 12 segmental resections., Results: There was no perioperative mortality. One patient who underwent PD with right trisegmentectomy for gallbladder cancer developed postoperative liver failure that improved with supportive management. Two patients developed bile leaks that resolved with conservative management. One patient developed a pancreatic leak/hemorrhage and required a completion pancreatectomy. Mean hospital stay was 14 days (range 7 to 42 days). Median follow-up was 30 months (range 3 to 76 months). Patients undergoing resection for neuroendocrine tumors had a better 5-year survival than those with hepatobiliary malignancies (100% vs 37% p = 0.01)., Conclusions: Combined resection of the liver and pancreas can be performed safely. The need for combined partial hepatectomy and pancreatectomy to remove malignancy should not be considered a contraindication to resection in selected patients., (Copyright 2010 American College of Surgeons.

Introduction: Strategies to reduce red blood transfusion utilization in cancer patients undergoing operation are needed., Hypothesis: Postoperative epoetin alfa (40,000 units subcutaneous on postoperative days 1 and 7) is associated with improved hematologic parameters in patients undergoing major abdominal surgery for malignancy., Materials and Methods: Prospective, blinded, randomized trial of epoetin alfa (40,000 units subcutaneous on postoperative days 1 and 7) versus placebo in patients undergoing major abdominal operation for malignancy. Primary endpoints were immature reticulocyte fraction, reticulocyte count, and hemoglobin, which were measured on postoperative days 4, 7, and between 14 and 20. Secondary endpoints were transfusions and complications in the 2 groups., Results: Forty patients were enrolled. There were no significant differences in immature reticulocyte fraction (P = 0.78), reticulocyte count (P = 0.42), or hemoglobin (0.35) in patients randomized to receive epoetin alfa versus placebo. There was no significant difference in red blood cell transfusion rate or postoperative complications in patients who received epoetin alfa compared with placebo., Discussion: The use of postoperative epoetin alfa (40,000 units subcutaneous on postoperative days 1 and 7) in patients undergoing major operation for abdominal or pelvic malignancy is not supported by this randomized trial.

We present a case of a 10-month-old boy with BA who developed HCC and was treated with liver transplantation. A four-month-old boy was referred to our institution because of persistent jaundice, hepatomegaly, and coagulopathy. He had been treated for the diagnosis of neonatal hepatitis at an outside hospital. He was evaluated and was accepted as a liver transplant candidate, and was subsequently transplanted with a deceased donor liver allograft at the age of 10 months. His native liver showed established cirrhosis because of BA with one focus of moderately differentiated HCC, measuring 0.7 cm in a diameter with microscopic vascular invasion in pathological study. The postoperative course was uneventful, and he is well without recurrence four months after liver transplantation. The occurrence of HCC in a child under one yr old is extremely rare, and only three cases are reported so far including our case.

Purpose: 17-(demethoxy), 17-allylamino geldanamycin (17-AAG) suppresses growth in some cancers by inhibiting Heat shock protein 90 (Hsp90). We examined the effects of 17-AAG-mediated Hsp90 inhibition on human hepatocellular carcinoma (HCC) growth in vitro and in vivo., Methods: Human HCC cell lines, Hep3B and HuH7, were exposed to 17-AAG and cell viabilities and apoptosis were determined. Cell cycle profiles were analyzed and the G(2)/M cell cycle checkpoint proteins cdc2 and cyclin B1 were examined. Studies were performed to determine whether 17-AAG-mediated cdc2 decrease was due to altered gene expression, transcription, or protein degradation. The effects of 17-AAG on Hep3B and HuH7 xenograft growth in athymic nude mice were also examined., Results: Hep3B and HuH7 treated with 17-AAG versus untreated controls showed decreased cell viability and increased apoptosis. Cells treated with 17-AAG also showed an increased fraction in G(2)/M phase and an associated decrease in cdc2 through protein degradation rather than through other mechanisms. Hsp90 inhibition by 17-AAG also decreased HCC xenograft growth in association with decreased cdc2 expression., Conclusions: 17-AAG-mediated inhibition of Hsp90 abrogates human HCC cell growth in vitro and in vivo through cdc2 decrease, which in turn induces G(2)/M cell cycle arrest and apoptosis. Hsp90 is a mediator of HCC growth and survival and its inhibition may serve as a potential treatment.

Management of hepatocellular carcinoma in the early cirrhotic remains controversial. The exact role of liver transplantation versus resection remains to be determined. The following short review attempts to present the evidence for the respective roles of liver transplantation versus liver resection in early stage HCC.

Objective: The purpose of this study was to assess indebtedness among academic surgeons and its repercussions on personal finances, quality of life, and career choices., Summary Background Data: The influence of educational debt on academic surgical career choices and quality of life is unknown. We hypothesized that educational debt affects professional choices and quality of life., Methods: A web-based survey was designed to assess respondent demographics, educational and consumer indebtedness, and the influence of educational debt on career choices and quality of life among academic surgeons., Results: Five hundred fifty-five surgeons responded (20.6% response rate). Two hundred seventy-four (66%) respondents finished postgraduate training with educational debt, 139 (34%) reported no debt, and 142 (26%) did not respond. Among those with educational debt, mean educational debt was $90,801 and mean noneducational consumer debt was $32,319. Individuals without educational debt reported a mean of $15,104 of noneducational consumer debt (P < 0.001) and had higher mean salaries (P = 0.017) versus those with educational debt. Eighty-seven percent of respondents with educational debt would make the same career choice again. However, 35% acknowledged it placed a strain on their relationship with their significant other, 48% felt it influenced the type of living accommodations they could afford, and 29% reported it forced their significant other to work. Alarmingly, 32% of academic surgeons would not recommend their career choice to their children or medical students., Conclusions: Many academic surgeons reported that their educational debt affected their academic productivity, career choices, and quality of life. Consequently, efforts to mitigate the impact of educational debt on academic surgeons are required to ensure medical students continue to pursue academic surgical careers.

Gallbladder duplication is a rare congenital biliary anomaly with different morphologies depending on events at embryogenesis. This case report describes a symptomatic duplicate gallbladder arising from the left intrahepatic duct 10 years after an open cholecystectomy: this is the rarest form of gallbladder duplication. The symptoms resolved following a second open cholecystectomy. This case illustrates the importance of preoperative imaging, intraoperative cholangiography, and a high index of suspicion of anomalous gallbladder anatomy in the diagnosis and management of this rare condition. We discuss the classification of anomalous gallbladder anatomy and review previous cases, to propose a modification of the common classification scheme.

The atrophy-hypertrophy complex (AHC) refers to the controlled restoration of liver parenchyma following hepatocyte loss. Different types of injury (e.g., toxins, ischemia/reperfusion, biliary obstruction, and resection) elicit the same hypertrophic response in the remnant liver. The AHC involves complex anatomical, histological, cellular, and molecular processes. The signals responsible for these processes are both intrinsic and extrinsic to the liver and involve both physical and molecular events. In patients in whom resection of large liver malignancies would result in an inadequate functional liver remnant, preoperative portal vein embolization may increase the remnant liver sufficiently to permit aggressive resections. Through continued basic science research, the cellular mechanisms of the AHC may be maximized to permit curative resections in patients with potentially prohibitive liver function.

Background: The definition of what is unresectable in liver surgery is controversial. Problems that many believe render patients unresectable can currently be resected using advanced techniques of liver surgery. This study assesses liver resection in patients who were unresectable with standard liver resection but were potentially resectable using an aggressive approach to liver surgery., Study Design: From 1997 to 2007, 830 adult patients undergoing hepatectomy were reviewed. Patients were categorized as having unresectable disease by standard resection if the disease could not be resected without resection of the IVC, hepatic vasculature, or because of tumor extent., Results: One hundred sixteen patients were initially believed to have unresectable disease but went on to laparotomy. Eighteen patients were unresectable at operation, although 98 patients were resected. Seventy-eight trisectionectomies; 18 lobectomies; 1 mesohepatectomy; and 1 segment 5, 6 resection, combined with pancreaticoduodenectomy, nephrectomy, and colectomy, were performed. Fourteen patients also had pancreatic resections. Vascular reconstructions were performed on the IVC (n = 35), hepatic veins (n = 21), portal vein (n = 34), and hepatic artery (n = 5). Hypothermic perfusion of the liver was used in 12 patients (4 ex vivo, 8 in situ cold perfusion). Patients undergoing resection had 6% mortality with a morbidity of 35%. Median survival was 37 months (95% CI, 34-42 months). Five-year actuarial survival was 32%., Conclusions: Patients with liver tumors considered "unresectable" by standard liver resection should be considered for resection with an aggressive approach to liver surgery. Five-year survival of approximately one-third of patients can be expected.

Background: While the main effect of hepatitis C virus (HCV) is hepatitis, HCV is also known to cause a variety of systemic immunologic inflammatory abnormalities. The effect of HCV infection on the biliary tract after liver transplantation (LT) is not well understood. The aim of the current study is to determine if recurrence of hepatitis C affects biliary complications after LT, with special reference to late biliary anastomotic strictures (LBAS)., Methods: A total of 688 consecutive adult LT recipients with a choledochocholedochostomy without T-tube placement between 1990 and 2005 were reviewed. Biliary anastomotic stricture was confirmed by endoscopic retrograde cholangiopancreatography. LBAS was defined as stricture that occurred 30 days or more after LT. Early HCV recurrence was defined as recurrence within 6 months after LT., Results: LBAS occurred in 55 patients (8% of total). Patients with HCV infection had a higher occurrence of LBAS than non-HCV patients (11% vs. 5%, P=0.0093). Among HCV patients, those with early HCV recurrence had an exceedingly high rate of LBAS (16%). In multivariate analyses, early recurrence of hepatitis C (P<0.0001), as well as occurrence of hepatic artery thrombosis (P=0.0018) and prolonged cold ischemic time (P=0.034), were independent risk factors affecting LBAS. Among HCV patients, those with LBAS had a significantly higher hepatitis activity index score (3.1 vs. 1.4, P<0.0001) and fibrosis stage (0.9 vs. 0.4, P<0.0001) as compared to patients without LBAS., Conclusion: Patients with early recurrence of HCV have increased occurrence of late biliary anastomotic stricture after liver transplantation.

Listeria monocytogene is a well-recognized cause of bacteremia in immunocompromised individuals, including solid organ transplant recipients, but has been rarely reported following orthotopic liver transplantation. We describe a case of listeria meningitis that occurred within a week after liver transplantation. The patient developed a severe headache that mimicked tacrolimus encephalopathy, and was subsequently diagnosed with listeria meningitis by cerebrospinal fluid culture. The infection was successfully treated with three-week course of intravenous ampicillin. Recurrent hepatitis C followed and was successfully treated with interferon alfa and ribavirin. Fourteen cases of listeriosis after orthotopic liver transplantation have been reported in the English literature. Most reported cases were successfully treated with intravenous ampicillin. There were four cases of listeria meningitis, and the mortality of them was 50%. Early detection and treatment of listeria meningitis are the key to obtaining a better prognosis.

Background: Liver transplantation (LT) from controlled donation after cardiac death (DCD) donors has increased steadily during the past decade because of the donor shortage in the United States. Although early reports of LT from DCD donors provided evidence for acceptable outcomes, long-term graft and patient survival rates from these procedures have been reviewed only recently., Methods: From February 1990 to June 2006, 1209 LTs were performed from donation after brain death (DBD) donors, and 24 were performed from DCD donors at our institution. Detailed review of donor and recipient characteristics, and survival rates were evaluated in the two groups., Results: One- and 3-year patient survival was similar in both groups, (DCD 86.8%, 81.7% vs. DBD 84.0%, 76.0%, respectively; P=0.713). Graft survival appeared inferior in the DCD group compared with the DBD group at 1 year (69.1% vs. 78.7%) and 3 years (58.6% vs. 70.2%), but there was no statistical difference (P=0.082). There were no significant differences in hepatic artery thrombosis, portal vein thrombosis, primary nonfunction, and biliary stricture between the two groups. All cases with biliary stricture in DCD group finally led to graft loss, and all survived with retransplantation., Conclusion: The outcome of LT from DCD donors remains acceptable in our institution. Although biliary complication rate was similar in two groups, the consequence of this complication in DCD was more severe and often led to graft loss. Close observation of biliary complications after LT from DCD donors would be beneficial.

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.

Background: Patients with hepatic and pulmonary metastases from colorectal cancer (CRC) may benefit from aggressive surgical therapy. We examined the longterm outcomes of patients who underwent both lung and liver resections for colorectal metastases over a 10-year period., Study Design: Four hundred twenty-three hepatectomies were performed for metastatic CRC between 1992 and 2002 at two university-affiliated hospitals. Patients who underwent both lung and liver resections for metastatic CRC were studied. Demographic, perioperative, and survival data were evaluated by retrospective chart review. Disease-free survival (DFS) and overall survival (OS) were evaluated by Kaplan-Meier analysis and survival curves were compared using the log-rank test., Results: Thirty-nine patients underwent both lung and liver resections for metastatic CRC. Eleven patients (28%) underwent staged liver and lung metastasectomy from synchronously identified metastases. Twenty-eight patients (72%) underwent sequential metastasectomy because of recurrent disease. The median disease-free and overall survivals after initial metastasectomy were 19.8 and 87 months, respectively. Serial metastasectomy was common in this patient population. The mean number of metastasectomies performed was 2.6 per patient (range 1 to 4). There was no difference in overall survival for patients with synchronous versus metachronous presentation of liver and lung metastases (p=0.45). The site of first recurrence after initial metastasectomy was, most commonly, the lung (n=19, 49%), followed by the liver (n=8, 21%). Nineteen patients (49%) underwent subsequent resections for recurrences. Seven patients (18%) underwent 2 or more liver resections for recurrent disease, and 12 (31%) underwent multiple lung resections., Conclusions: An aggressive multidisciplinary surgical approach should be undertaken for recurrent CRC metastases. In selected patients, serial metastasectomy for recurrent metastatic disease is safe and results in excellent longterm survival after CRC resection.

Background: Early recurrence (ER) (<1 year) after liver resection is one of the most important factors that impact the prognosis of patients with hepatocellular carcinoma (HCC). We sought to determine factors associated with ER of HCC and examine the outcomes thereafter., Study Design: From March 2001 to June 2003, 56 patients underwent hepatic resection for HCC at University of Toronto and were prospectively followed with median followup of 24 months. Patients with ER were compared with those who remained disease free for more than 1 year. Patient characteristics, tumor stage, and operative procedures were evaluated for their prognostic significance by univariate and multivariable analysis. Time to recurrence and time to death were analyzed using Kaplan-Meier survival curves and compared using log-rank analysis., Results: The initial procedure in all patients was surgical hepatectomy. ER occurred in 21 patients (38%), 31 (55%) remained disease free for more than 1 year, and 4 (7%) were omitted from evaluation because of early (<30 days) death. Median survival after initial hepatic resection for those with ER was 27 months, and 2-year survival was 54%. There were no deaths in the group that remained disease free for more than 1 year (100% 2-year survival, p < 0.05). By multivariate analysis, vascular invasion and positive microscopic margins were significant predictors when all 4 variables were considered in the model (p < 0.05). After ER, 11 of 21 patients (52%) underwent additional therapy with significant improvement in median survival (33 months) compared with those not eligible for conventional therapy (18 months, p = 0.05)., Conclusions: ER after liver resection for HCC is the leading cause of death during the first 2 years after potentially curative resection. ER will develop in approximately 75% of patients with either vascular invasion or positive margins. For patients with these predictive factors additional treatment might be advised.

Background: Complete resection offers the only potential cure for ampullary carcinoma. We analyzed factors that contribute to treatment failure and survival in patients who underwent pancreaticoduodenectomy for ampullary carcinoma., Study Design: We retrospectively reviewed all patients who underwent pancreaticoduodenectomy between August 1994 and August 2003 for ampullary carcinoma. Demographic, clinical, and pathologic data were collected. Chi-square analysis was used for categorical data and the t-test was used for continuous variables. Kaplan-Meier analyses were compared using the log-rank test to examine patient survival., Results: Forty-three patients (24 men) aged 63.7 +/- 11.4 years (standard deviation) were followed for a mean of 23.9 months (median 660 days, range 18 to 2,249 days). Jaundice (n = 33) and weight loss (n = 13) were the most common presenting symptoms. Stage (p < 0.01) and degree of differentiation (p < 0.029) were significant predictors of failure by univariate analysis. But only stage (p < 0.04) was a significant predictor by multivariate analysis. Further analysis revealed that nodal status (p < 0.001), but not tumor grade, was a significant predictor of treatment failure. Neither demographic nor clinical variables were significant predictors. Five-year overall and disease-free survival rates were 67.4% and 51.4%, respectively. Both metastases and disease recurrence had significant impact on patient survival., Conclusions: Tumor stage is associated with treatment failure after pancreaticoduodenectomy for ampullary carcinoma and may identify candidates for adjuvant therapy. Because an aggressive surgical approach can be adopted safely with the best chance for cure, we recommend that pancreaticoduodenectomy be offered to all patients with ampullary tumors when malignancy or dysplasia is in question.

The shortage of deceased organ donors has created a need for right lobe living donor liver transplantation (RLDLT) in adults. Concerns regarding donor safety, however, necessitate continuous assessment of donor acceptance criteria and documentation of donor morbidity. We report the outcomes of our first 101 donors who underwent right lobectomy between April 2000 and November 2004. The cohort comprised 58 men and 43 women with a median age of 37.8 years (range: 18.6-55 years); median follow-up is 24 months. The middle hepatic vein (MHV) was taken with the graft in 55 donors. All complications were recorded prospectively and stratified by grade according to Clavien's classification. Overall morbidity rate was 37%; all complications were either grade 1 or 2, and the majority occurred during the first 30 days after surgery. Removal of the MHV did not affect morbidity rate. There were significantly fewer complications in the later half of our experience. All donors are well and have returned to full activities. With careful donor selection and specialized patient care, low morbidity rates can be achieved after right hepatectomy for living donor liver transplantation.

Background: Whether peritoneal dialysis is a risk factor for the development of intra-abdominal infection (IAI) after simultaneous pancreas kidney (SPK) transplantation is controversial., Methods: We investigated the incidence of IAI, and patient and pancreas graft survival rates of 120 patients that received SPK between November 1995 and August 2003. All patients were dialysis-dependent prior to transplantation; mean duration of peritoneal dialysis (PD; n=52) and hemodialysis (HD; n=68) was 20+/-15 months and 23+/-16 months, respectively., Results: IAI developed in five PD and six HD patients (P=0.88). The time of diagnosis of IAI and the spectrum of organisms cultured were similar in the two groups of patients. Age, duration of dialysis, and method of exocrine drainage did not have a significantly impact on infection rate. Patient and pancreas graft survival rates were 92.3% and 88.4% in the PD group and 95.5% and 92% HD group (p=ns) after a mean follow-up of 42+/-27 months and 39+/-27 months, respectively. Overall patient and pancreas graft survival was not significantly affected by IAI., Conclusions: PD does not adversely affect IAI rate and is a safe mode of dialysis for patients awaiting SPK transplantation.

Background: The value of magnetic resonance cholangiography (MRC) in assessing potential adult-to-adult living liver transplant (ALDLT) donors remains poorly defined. The purpose of this study is to determine the accuracy of MRC in assessing biliary anatomy with intraoperative confirmation., Methods: A prospective cohort of 30 ALDLT donors who underwent right hepatectomy from October 2000 to July 2003 was evaluated. MRC was performed using a heavily T2 weighted radial slab technique. MRC was interpreted preoperatively by a radiologist and a surgeon and compared with the intraoperative biliary findings in all patients derived from cholangiography (IOC) and bile duct exploration. The sensitivity, specificity, and positive and negative predictive values of MRC for aberrant biliary anatomy were calculated., Results: MRC suggested normal, aberrant, and indeterminate biliary anatomy in 16, 12, and 2 donors, respectively. IOC revealed normal and aberrant biliary anatomy in 17 and 13 patients, respectively. MRC demonstrated biliary anatomy accurately in 27 of 30 patients. The sensitivity, specificity, positive predictive, and negative predictive values of MRC in detecting aberrant biliary anatomy were 92%, 100%, 100%, and 94%, respectively., Conclusions: Preoperative MRC accurately depicts biliary anatomy in potential ALDLT donors and may guide the intraoperative management of the biliary tract.

As the population ages, the transplant community will continue to see "elderly" patients with end-stage kidney disease who are seeking transplantation. In this report we describe long-term outcomes of 315 primary kidney transplants performed at the University of Florida in recipients aged > or = 60 years and compare them to results from 3 younger recipient cohorts. Among recipients > or = 60 years, patient survival was significantly worse than for younger recipients but no differences in graft or death-censored graft survival were seen. We suspect that although patient survival was worst in the oldest group, there were likely other causes of graft loss within the younger groups that balanced the effects of death on graft survival in the oldest group. Among recipients aged > or = 60 years, patient survival at 10 years was 55% for living-donor kidney recipients and 46% for deceased-donor kidney recipients. African-American recipients had a higher risk of mortality and graft loss in all age groups after deceased donor kidney transplantation but not after living donor transplantation. Delayed graft function negatively impacted outcomes among all recipients and the adverse effects were greater after deceased donor than living donor transplantation. These effects were also seen within the oldest recipient age group. Increased donor age was a significant risk factor for death and graft loss among all age groups after deceased donor kidney transplantation but not among living-donor kidney recipients. More specifically, recipients aged > or = 60 years who received kidneys from donors > or = 60 years demonstrated significantly worse outcomes when compared to those receiving donor kidneys < 60 years. The presence of diabetes mellitus in recipients > or = 60 years was not a significant risk factor for mortality or graft loss after transplantation. Acceptable results can be obtained after kidney transplantation in recipients aged > or = 60 years. Future investigations should focus on improving recipient selection in the elderly population, identifying strategies to minimize DGF in deceased donor kidneys, understanding all variables involved in the risk associated with recipient race, and increasing living donor transplantation across all age groups.

We report a case of a 13-year-old girl with trichotillomania. A plain abdominal radiograph and axial CT scan revealed a well-defined mass within the stomach. Gastrotomy was performed and a 19 x 11 x 2-cm trichophytobezoar was delivered intact.
