Long-term outcome after living donor liver transplantation compared to donation after brain death in autoimmune liver diseases: Experience from the European Liver Transplant Registry.

Knowledge of living donor liver transplantation (LDLT) for autoimmune liver diseases (AILDs) is scarce. This study analyzed survival in LDLT recipients registered in the European Liver Transplant Registry with autoimmune hepatitis, primary biliary cholangitis, primary sclerosing cholangitis (PSC) and the non-autoimmune disorder alcohol-related cirrhosis. In total, 29 902 individuals enrolled between 1998 and 2017 were analyzed, including 1003 with LDLT. Survival from >90 days after LDLT for AILDs in adults was 85.5%, 74.2%, and 58.0% after 5, 10, and 15 years. Adjusted for recipient age, sex, and liver transplantation era, adult PSC patients receiving LDLT showed increased mortality compared to donation after brain death (DBD) (hazard ratio [HR] = 1.95, 95% confidence interval [CI] = 1.36-2.80, p < .001). Pediatric PSC patients showed also increased mortality >90 days after LDLT compared to DBD (HR = 3.00, 95% CI 1.04-8.70, p = .043). Multivariate analysis identified several risk factors for death in adult PSC patients receiving LDLT including a male donor (HR = 2.49, p = .025). Adult PSC patients with LDLT versus DBD conferred increased mortality from disease recurrence (subdistribution hazard ratio [subHR] = 5.36, p = .001) and biliary complications (subHR = 4.40, p = .006) in multivariate analysis. While long-term outcome following LDLT for AILD is generally favorable, PSC patients with LDLT compared to DBD might be at increased risk of death.

Perceptions of porta-celiac vascular models for hepatic surgery and their use in residency training.

BACKGROUND: Primary aspect of hepatic navigation surgery is the identification of source vascular details to preserve healthy liver which has a vascular anatomy quite challenging for the young surgeons. The purpose was to determine whether three-dimensional (3D) vascular pattern models of preoperative computed tomography (CT) images will assist resident-level trainees for hepatic surgery. METHODS: This study was based on the perception of residents who were presented with 5 different hepatic source vascular patterns and required to compare their perception level of CT, and 1:1 models in terms of importance of variability, differential of patterns and preoperative planning. RESULTS: All residents agree that models provided better understanding of vascular source and improved preplanning. Five stations provided qualitative assessment with results showing the usefulness of porta-celiac models when used as anatomical tools in preplanning (p = 0.04), simulation of interventional procedures (p = 0.02), surgical education (p = 0.01). None of the cases had scored less than 8.5. Responses related to understanding variations were significantly higher in the perception of the 3D model in all cases, furthermore 3D models were more useful for seniors in more complex cases 3 and 5. Some open-ended answers: "The 3D model can completely change the operation plan" One of the major factors for anatomical resection of liver transplantation is the positional relationship between the hepatic arteries and the portal veins. CONCLUSION: The plastic-like material presenting the hepatic vascularity enables the visualization of the origin, pattern, shape, and angle of the branches with appropriate spatial perception thus making it well-structured.

The Relationship Between Nutritional Status, Performance Status, and Survival Among Pancreatic Cancer Patients.

Aim: The purpose of this study was to identify the nutritional and performance status of Pancreatic Cancer (PanCa) patients and to determine the relationship between these parameters and their survival time.Material and Methods: Ninety-six PanCa patients [59.6% F, 61.4% M; mean age: 60.7 (min:28, max:80) years] were followed up for 6-24 months. The Patient Generated Subjective Global Assessment (PG-SGA) and Eastern Comparative Oncology Group (ECOG) scale were performed. Anthropometric measurements [height, weight, mid-upper arm circumference (MUAC), calf circumference (CC) and triceps skin fold thickness (TSF)], hand grip strength (HGS) were recorded. Survival analyses were conducted using Kaplan-Meier curves.Results: Malnutrition was observed in 85.5% (n = 82) and 54.2% of all patients had poor performance status. A positive correlation was observed between malnutrition and ECOG scale of the patients (P < .01). Antropometric measurements for women and men, respectively, were 34.4 ± 3.03-34.6 ± 3.43 cm for CC; 26.9 ± 3.47-26.05 ± 3.37 cm for MUAC; 20.5 ± 6.3-13.02 ± 7.7 mm for TSF; - 31.02 ± 7.64-20.13 ± 6.04 kg for HGS. Survival time of patients with SGA-A and B was 38.0 ± 6.6 months and of those with SGA-C was 12.0 ± 3.1 months (P = .000).Conclusion: Malnutrition negatively affected both performance status and survival time among PanCa patients.

Predictive Factors for Survival in Children Receiving Liver Transplants for Wilson's Disease: A Cohort Study Using European Liver Transplant Registry Data.

Liver transplantation (LT) is a rescue therapy for life-threatening complications of Wilson's disease (WD). However, data on the outcome of WD patients after LT are scarce. The aim of our study was to analyze a large pediatric WD cohort with the aim of investigating the longterm outcome of pediatric WD patients after LT and to identify predictive factors for patient and transplant survival. This is a retrospective cohort study using data of all children (<18 years) transplanted for WD enrolled in the European Liver Transplant Registry from January 1968 until December 2013. In total, 338 patients (57.6% female) transplanted at 80 different European centers (1-26 patients per center) were included in this study. The median age at transplantation was 14.0 years (interquartile range [IQR], 11.2-16.1 years); patients were followed up for a median of 5.4 years (IQR, 1.0-10.9 years) after LT. Overall patient survival rates were high with 87% (1-year survival), 84% (5-year survival), and 81% (10-year survival); survival rates increased considerably with the calendar year (P < 0.001). Early age at LT, living donation, and histidine tryptophan ketoglutarate preservation liquid were identified as risk factors for poor patient survival in the multivariate analysis. LT is an excellent treatment option for pediatric patients with WD and associated end-stage liver disease. Longterm outcome in these patients is similar to other pediatric causes for LT. Overall patient and graft survival rates improved considerably over the last decades. To improve future research in the field, the vast variability of allocation strategies should be harmonized and a generally accepted definition or discrimination of acute versus chronic WD needs to be found.

Survival of children after liver transplantation for hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) in childhood differs from adult HCC because it is often associated with inherited liver disease. It is, however, unclear whether liver transplantation (LT) for HCC in childhood with or without associated inherited disease has a comparable outcome to adult HCC. On the basis of data from the European Liver Transplant Registry (ELTR), we aimed to investigate if there are differences in patient and graft survival after LT for HCC between children and adults and between patients with underlying inherited versus noninherited liver disease, respectively. We included all 175 children who underwent LT for HCC and were enrolled in ELTR between 1985 and 2012. Of these, 38 had an associated inherited liver disease. Adult HCC patients with (n = 79) and without (n = 316, matched by age, sex, and LT date) inherited liver disease served as an adult comparison population. We used multivariable piecewise Cox regression models with shared frailty terms (for LT center) to compare patient and graft survival between the different HCC groups. Survival analyses demonstrated a superior longterm survival of children with inherited liver disease when compared with children with HCC without inherited liver disease (hazard ratio [HR], 0.29; 95% CI, 0.10-0.90; P = 0.03) and adults with HCC with inherited liver disease (HR, 0.27; 95% CI, 0.06-1.25; P = 0.09). There was no survival difference between adults with and without inherited disease (HR, 1.05; 95% CI, 0.66-1.66; P = 0.84). In conclusion, the potential survival advantage of children with an HCC based on inherited disease should be acknowledged when considering transplantation and prioritization for these patients. Further prospective studies accounting for tumor size and extension at LT are necessary to fully interpret our findings. Liver Transplantation 24 246-255 2018 AASLD.

Progress in surgical and nonsurgical approaches for hepatocellular carcinoma treatment.

BACKGROUND: Hepatocellular carcinoma (HCC) is a complex and heterogeneous malignancy, frequently occurs in the setting of a chronically diseased organ, with multiple confounding factors making its management challenging. HCC represents one of the leading causes of cancer-related mortality globally with a rising trend of incidence in some of the developed countries, which indicates the need for better surgical and nonsurgical management strategies. DATA SOURCES: PubMed database was searched for relevant articles in English on the issue of HCC management. RESULTS: Surgical resection represents a potentially curative option for appropriate candidates with tumors detected at earlier stages and with well-preserved liver function. The long-term outcome of surgery is impaired by a high rate of recurrence. Surgical approaches are being challenged by local ablative therapies such as radiofrequency ablation and microwave ablation in selected patients. Liver transplantation offers potential cure for HCC and also correction of underlying liver disease, and minimizes the risk of recurrence, but is reserved for patients within a set of criteria proposed for a prudent allocation in the shortage of donor organs. Transcatheter locoregional therapies have become the palliative standard allowing local control for intermediate stage patients with noninvasive multinodular or large HCC who are beyond the potentially curative options. The significant survival benefit with the multikinase inhibitor sorafenib for advanced HCC has shifted the direction of research regarding systemic treatment toward molecular therapies targeting the disregulated pathways of hepatocarcinogenesis. Potential benefit is suggested from simultaneous or sequential multimodal therapies, and optimal combinations are being investigated. Despite the striking progress in preclinical studies of HCC immunotherapy and gene therapy, extensive clinical trials are required to achieve successful clinical applications of these innovative approaches. CONCLUSION: Treatment decisions have become increasingly complex for HCC with the availability of multiple surgical and nonsurgical therapeutic options and require a comprehensive, multidisciplinary approach.

Prevention and acute management of biliary injuries during laparoscopic cholecystectomy: Expert consensus statement.

Gallstone disease is very common and laparoscopic cholecystectomy is one of the most common surgical procedures all over the world. Parallel to the increase in the number of laparoscopic cholecystectomies, bile duct injuries also increased. The reported incidence of bile duct injuries ranges from 0.3% to 1.4%. Many of the bile duct injuries during laparoscopic cholecystectomy are not due to inexperience, but are the result of basic technical failures and misinterpretations. A working group of expert hepatopancreatobiliary surgeons, an endoscopist, and a specialist of forensic medicine study searched and analyzed the publications on safe cholecystectomy and biliary injuries complicating laparoscopic cholecystectomy under the organization of Turkish Hepatopancreatobiliary Surgery Association. After a series of e-mail communications and two conferences, the expert panel developed consensus statements for safe cholecystectomy, management of biliary injuries and medicolegal issues. The panel concluded that iatrogenic biliary injury is an overwhelming complication of laparoscopic cholecystectomy and an important issue in malpractice claims. Misidentification of the biliary system is the major cause of biliary injuries. To avoid this, the "critical view of safety" technique should be employed in all the cases. If biliary injury is identified intraoperatively, reconstruction should only be performed by experienced hepatobiliary surgeons. In the postoperative period, any deviation from the expected clinical course of recovery should alert the surgeon about the possibility of biliary injury.

Turkish HPB Surgery Association consensus report on hepatic cystic Echinococcosis (HCE).

Objectives: Cystic Echinococcosis (CE) is one of the important problems of the Eurasian region. We aimed to prepare a consensus report in order to update the treatment approaches of this disease. This study was conducted by Turkish HPB Surgery Association. Material and Methods: This study was conducted with the modified Delphi model. For this purpose, we conducted a three-stage consensus-building approach. Results: Six topics, including diagnosis, medical treatment, percutaneous treatment, surgical treatment, management of complications and posttreatment follow-up and recurrences in HCE were discussed. Conclusion: The expert panel made recommendations for every topic.

Life-threatening abdominal injury during a soccer game: a rare clinical case.

Soccer (football) is a popular sport worldwide and can result in severe abdominal injuries. Nevertheless, the necessity of surgical intervention for abdominal organ injuries has been reported rarely. We report a case who was injured during a soccer game who underwent abdominal surgery. Distal subtotal pancreatectomy, splenectomy, cholecystectomy, and choledochotomy + T-tube drainage were performed. He was discharged on the postoperative seventh day without any complication.

Fat replacement of the malignant pancreatic tissue after neoadjuvant therapy.

Pancreatic lipomatosis is characterized as massive lipid infiltration of the pancreatic tissue. Although its etiology is ill defined; obesity, diabetes mellitus, chronic pancreatitis, hereditary pancreatitis, and conditions that cause pancreatic ductal obstruction, for example tumors and stones, are related to its pathogenesis. Recently, with the increased use of computerized tomography and magnetic resonance imaging, it has become possible to observe the fat replacement of the pancreas. Herein, we report a 60-year-old man complaining of abdominal pain and weight loss. Preoperative work-up revealed a locally advanced (Stage III) pancreatic adenocarcinoma. Multimodal treatment was carried out and a 100% complete response was detected after neoadjuvant therapy. The patient underwent a standard pancreaticoduodenectomy, without complications. The tissue pathology revealed lipomatosis of the pancreas. He was disease-free and symptom-free at 1 year follow-up. To our knowledge, this is the first report in the literature of pancreatic head carcinoma with total fat replacement of the pancreas after neoadjuvant chemoradiotherapy.

Postoperative gemcitabine alone and concurrent with radiation therapy in locally advanced pancreatic carcinoma.

AIMS AND BACKGROUND: To evaluate the treatment results of gemcitabine alone and concurrent with radiotherapy after R0/R1 resection of locally advanced pancreatic cancer. METHODS AND STUDY DESIGN: From 1999 to 2005, 55 patients with stage II resected pancreatic cancer treated with gemcitabine-based radiochemotherapy were retrospectively evaluated. Initially, one cycle of induction gemcitabine was administered and followed by weekly gemcitabine concurrent with radiotherapy. After the completion of radiochemotherapy, patients received 3 additional courses of gemcitabine. RESULTS: Thirteen patients were stage IIA and 42 were stage IIB. Forty-six patients (83.6%) had R0 and 9 patients (16.4%) had R1 resection. All of the patients received induction chemotherapy and radiotherapy, all but 3 received concurrent radiochemotherapy, and 46 (84%) patients received maintenance chemotherapy. During induction, concurrent and maintenance phases of the protocol, 11%, 13.5% and 19.5% of the patients had at least one > or = grade 3 toxicity, respectively. Within a median 47 months (range, 34-105) of follow-up, 4 (7.3%) patients had isolated local recurrence, 5 (9%) patients had local recurrence and distant metastases, and 27 (49%) had only distant metastases. Median disease-free survival and overall survival were 13 (range, 4-105) and 19 months (range, 6-105), respectively. In multivariate analysis, nodal stage, AJCC stage and number of lymph nodes dissected were the significant factors affecting disease-free survival whereas Karnofsky performance status was the only significant factor for overall survival. CONCLUSIONS: The prognosis for pancreatic cancer remains poor despite adjuvant radiochemotherapy. More aggressive treatments should be considered in patients with unfavorable prognostic factors.

Xanthogranulomatous pancreatitis treated by duodenum-preserving pancreatic head resection.

BACKGROUND: Xanthogranulomatosis is an idiopathic, rare process in which lipid-laden histiocytes are deposited at various locations in the body. We present two cases who were treated by duodenum-preserving pancreatic head resection and eventually diagnosed as having xanthogranulomatous pancreatitis. METHODS: A 30-year-old caucasian man was admitted to our clinic for vague abdominal pain and epigastric dullness. Magnetic resonance cholangiopancreatography and endoscopic retrograde pancreatography suggested the existence of chronic pancreatitis. Another 34-year-old caucasian woman was admitted to our clinic because of right upper quadrant pain. Magnetic resonance cholangiopancreatography demonstrated a dilatation and stone of the main pancreatic duct. Based on a diagnosis of chronic pancreatitis, pancreatic head resection was planned and a laparotomy was performed in both of cases. RESULTS: In both cases, duodenum-preserving pancreatic head resection was performed. Macroscopic and microscopic findings revealed xanthogranulomatous inflammation, which led to a diagnosis of xanthogranulomatous pancreatitis. CONCLUSION: Although this type of pancreatitis is extremely rare, it is important to keep it in mind for a differential diagnosis because it may simulate chronic pancreatitis or a malignant tumor on imaging.

Gallstone ileus as an unexpected complication of cholelithiasis: diagnostic difficulties and treatment.

BACKGROUND: Gallstone ileus is a rare complication of cholelithiasis, mostly in the elderly. The aim of this study was to evaluate our experience with 12 gallstone ileus cases and discuss current opinion as reported in the literature. METHODS: Data of 12 patients operated between January 1998 and January 2008 with gallstone ileus were retrospectively studied. RESULTS: There were 12 cases (9 F, 75%; 3 M, 25%) with a mean age of 63.6 (50-80) years. Median duration of symptoms before admission to the hospital was 4.1 (1-15) days. Preoperative diagnosis was made in only five cases (41.6%). Enterolithotomy was done in nine cases (75%). Enterolithotomy and resection of the small intestine--required for decubital necrosis from the gallstone--was performed in one case (8.3%). In one case (8.3%), enterolithotomy was completed in one stage with cholecystectomy and closure of the fistula during acute surgery, and in another case (8.3%), enterolithotomy + primary suturing of the jejunal perforation was performed. There were two (16.6%) perioperative mortalities. CONCLUSION: Gallstone ileus remains a diagnostic challenge despite advances in imaging techniques, and pre-operative diagnosis is often delayed. Gallstone ileus should be suspected in all cases admitted to the emergency service with acute intestinal obstruction with a history of cholelithiasis, especially in the elderly and females.

Solid pseudopapillary neoplasms of the pancreas: Case series with a review of the literature.

BACKGROUND/AIMS: The solid pseudopapillary neoplasms are quite rare tumors of the pancreas, comprising roughly 1-2% of all pancreatic neoplasms. It has a low malignant potential and usually affects young females. Despite increasing number of articles in the last decade, there is still debate on the pathogenesis, malignant potential and optimal surgical strategy for the solid pseudopapillary neoplasms. MATERIALS AND METHODS: Medical recordings of 326 patients who were operated due to pancreatic mass were retrospectively analyzed. Patient demographics, presenting symptoms, surgical and pathologic characteristics of the tumor, postsurgical course, long-term survival, and other relevant data were extracted from patients' charts. RESULTS: Majority of the patients were female in consistency with the classic data in the literature. All the patients underwent curative intent resections. Tumors were commonly localized in the tail of the pancreas making distal pancreatectomy the most commonly performed surgical procedure. Mean tumor diameter was 5.8 centimeters with tumor sizes ranging from 1 to 19 cm. CONCLUSION: The solid pseudopapillary neoplasms of the pancreas is a rare tumor with low malignant potential, which is more common in females of reproductive age, with abdominal pain being their most common presentation. The short-term outcomes in patients following surgical R0 resection are excellent. However, proximal placement of the tumor and female gender may have slightly worse prognosis. We hope that our findings from a series of patients represent a contribution to the existing literature on SPN, and authors declare their willingness to provide further details for future meta-analyses.

Biliary intraductal papillary mucinous neoplasia: three case reports.

Intrahepatic cholangiocarcinoma is subdivided as mass-forming, periductal-infiltrating, and intraductal-growing types. Intraductal-growing type is an entity described in recent years as mucin-producing intrahepatic cholangiocarcinoma or intrahepatic (biliary) intraductal papillary mucinous neoplasia (b-IPMN). b-IPMN is classified as adenoma, borderline tumor, carcinoma in situ, and carcinoma, from benign to malignant. Using a different classification, b-IPMNs are subdivided into intestinal, pancreatobiliary, gastric, or oncocytic based on morphology of the cells forming the lesion and expression of MUC1, MUC2, and MUC5 gene proteins in the mucin family. The clinical and histopathological features of b-IPMN diagnosed in three cases are presented herein. Case 1 was classified as borderline. Case 2 was diagnosed as carcinoma in situ. Case 3 had large invasive areas, and was diagnosed as carcinoma. In all three cases, immunohistochemical investigation revealed MUC1 and MUC5AC to be positive, and MUC2 to be negative. We present herein three cases diagnosed with the clinical and pathological findings of a new entity in the literature, b-IPMN, and we discuss the macroscopic, histological, and immunohistochemical features.

Can hyperbaric oxygenation decrease doxorubicin hepatotoxicity and improve regeneration in the injured liver?

BACKGROUND/PURPOSE: Portal vein embolization is used in the treatment of hepatocellular cancer, with the purpose of enhancing resectability. However, regeneration is restricted due to hepatocellular injury following chemotherapeutics (e.g. doxorubicin). The aim of this study was to investigate whether hyperbaric oxygenation (HBO) can alleviate the hepatotoxicity of chemotherapy and improve regeneration in the injured liver. METHODS: Rats were allocated to four experimental groups. Group I rats were subjected to right portal vein ligation (RPVL); rats in groups II and III were administered doxorubicin prior to RPVL, with group III rats being additionally exposed to HBO sessions postoperatively; group IV rats was sham-operated. All rats were sacrificed on postoperative day 7, and liver injury was assessed by measuring alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels. Protein synthetic ability was determined based albumin levels and liver regeneration by the mitotic index (MI). RESULTS: The AST and ALT values of group II rats were significantly higher than those of group I, but not those of group III. Rats treated with doxorubicin and HBO (groups II and III) showed slightly but not significant differences in albumin levels than those subjected to only RPVL or sham-operated. The MI was significantly increased in groups I, II, and III, with the MI of group III rats significantly higher than those of group I rats. CONCLUSIONS: Based on our results, we conclude that HBO treatment has the potential to diminish doxorubicin-related hepatotoxicity and improve regeneration in the injured liver.

The effects of the Pringle maneuver on the pancreas: can octreotide be protective?

OBJECTIVE: The aim of this study was to evaluate the negative effects of the Pringle maneuver on pancreatic tissue with respect to the time of performing the maneuver. Moreover, the efficacy of octreotide therapy on pancreatic changes at the time of the Pringle maneuver was assessed. ANIMALS: Fifty male Wistar Albino rats were randomized into 5 groups. DESIGN: The groups were formed as follows: Group A: sham operation, Group B: Pringle maneuver for 30 min plus octreotide (PM30-OCT), Group C: Pringle maneuver for 60 min plus octreotide (PM60-OCT) and Group D: Pringle maneuver for 30 min plus 0.9 % saline solution (PM30-SS), Pringle maneuver for 60 min plus 0.9 % saline solution (PM60-SS, Group E). MAIN OUTCOME MEASURES: Blood samples for the evaluation of both amylase and lipase levels were taken via the portal vein. Levels of glutathione, glutathione reductase, catalase, myeloperoxidase, nitric oxide, xanthine oxidase, malondialdehyde, tumour necrosis factor alpha (TNF-alpha), and interleukin-1 beta (IL-1 beta) were assessed in the excised pancreatic tissue. RESULTS: In the octreotide-treated groups, the catalase level was significantly higher in Group B (PM30-OCT) as compared to Group C (PM60-OCT). Amylase, lipase, NO and IL-1 beta levels were higher in Group C (PM60-OCT). In the saline solution-treated groups, the catalase level was significantly higher in Group E (PM60-SS) than in Group D (PM30-SS) while nitric oxide and glutathione levels were found to be significantly lower in Group E (PM60-SS) than in Group D (PM30-SS). Comparison of those groups using the Pringle maneuver for 30 minutes, the octreotide-treated group (Group B, PM30-OCT) was found to have a higher degree of edematous change than the saline-treated group (Group D, PM30-SS). Among the treatment groups, TNF-alpha expression decreased with increasing occlusion time. CONCLUSION: In this study, pancreatic damage and the duration of the Pringle maneuver are directly proportional to each other. Moreover, the administration of octreotide prior to the Pringle maneuver contributed to the pancreatic damage.

Prognostic Value of Metastatic Lymph Node Ratio in Pancreatic Cancer.

Lymph node involvement in pancreatic adenocancer is one of the strongest predictors of prognosis. However, the extent of lymph node dissection is still a matter of debate and number of dissected nodes varies widely among patients. In order to homogenize this diverse group of patients and more accurately predict their prognosis, we aimed to analyze the effect of metastatic lymph node ratio as an independent prognostic factor. We retrospectively analyzed medical recordings of 326 patients with pancreatic cancer who were treated in a tertiary medical oncology center over a 10-year period. Both in univariate and multivariate analyses, metastatic lymph node ratio proved to be a strong predictor of prognosis which was unaffected from heterogeneity of our patient population and can be used to facilitate predict prognosis of patients who underwent lymph node dissection to various extents and with future studies it can emerge as a successful tool for creating prognostic subgroups of the disease.

A new technique of biliary reconstruction after "high hilar resection" of hilar cholangiocarcinoma with tumor extension to secondary and tertiary biliary radicals.

BACKGROUND: Radical operation for hilar cholangiocellular carcinoma, including extended hepatic resection, seems to improve prognosis by increasing the surgical curability rate. Nevertheless, high postoperative morbidity and mortality have been reported in patients with obstructive jaundice. We describe the technique of "high hilar resection" and a modification of bilioenteric anastomosis for drainage of the multiple secondary or tertiary biliary radicals. METHODS: Ten patients with advanced hilar cholangiocellular carcinoma underwent a high hilar resection with complete parenchymal preservation, and the biliary drainage was reconstructed by a sheath-to-enteric hepaticojejunostomy. Because of the technical difficulty caused by anastomosis line in the range of the biliary sheath, a modification was performed by dividing the biliary apertures of segments 5 and 4b. RESULTS: A high hilar resection was successfully performed, and all patients were discharged from the hospital in good condition. No patient died postoperatively. The proximal resection margin was tumor-free in all patients. One patient died after 29 months of peritoneal carcinomatosis. None of the patients developed local recurrence around the hepaticojejunostomy. The remaining nine patients are alive after a mean follow-up of 28.8 months after surgery without any signs of recurrence. CONCLUSION: In highly selected patients with advanced hilar cholangiocellular carcinoma, a high hilar resection is technically safe and oncologically justifiable. In combination with our new technique of sheath-to-enteric anastomosis, the patients considerably benefit from the preservation of liver parenchyma with low postoperative morbidity and very short in-hospital stay.

Management of iatrogenic bile duct injuries: Multiple logistic regression analysis of predictive factors affecting morbidity and mortality.

OBJECTIVE: Iatrogenic bile duct injuries remain a challenge for the surgeons to overcome. The predictive factors affecting morbidity and mortality are important for determining the best management modality. MATERIAL AND METHODS: The patients who referred to Ege University Faculty of Medicine after laparoscopy associated iatrogenic bile duct injury are grouped according to Strasberg-Bismuth classification system. The type and number of prior attempts, concomitant complications, and treatment modalities are analyzed using the SPSS version 18 (IBM, Chicago, IL, USA). The variables with p<0.10 were considered for univariate analysis and then evaluated for predictive factors by forward Logistic Regression method using multiple logistic regression analysis. RESULTS: According to the analysis of 105 patients who were referred during 2004-2014, the type and number of prior attempts are considered predictive factors in sepsis. In multiple logistic regression analysis, abscess formation, concomitant vascular injury, and serum bilirubin level are significantly effective in predicting mortality. CONCLUSION: The management of iatrogenic bile duct injuries should be carefully planned with a multidisciplinary approach. The predictive factors affecting morbidity and mortality are important in determining the best modality for managing iatrogenic bile duct injuries. Abscess formation, vascular injury, and serum bilirubin level are the potential risk factors. Therefore, we can strongly recommend immediate assessment of patients for prompt diagnosis and referring to an HPB center, to avoid further injuries.
