Routine End-ischemic Hypothermic Oxygenated Machine Perfusion in Liver Transplantation From Donors After Brain Death: A Randomized Controlled Trial.

OBJECTIVE: To assess whether end-ischemic hypothermic oxygenated machine perfusion (HOPE) is superior to static cold storage (SCS) in preserving livers procured from donors after brain death (DBD). BACKGROUND: There is increasing evidence of the benefits of HOPE in liver transplantation, but predominantly in the setting of high-risk donors. METHODS: In this randomized clinical trial, livers procured from DBDs were randomly assigned to either end-ischemic dual HOPE for at least 2 hours or SCS (1:3 allocation ratio). The Model for Early Allograft Function (MEAF) was the primary outcome measure. The secondary outcome measure was 90-day morbidity (ClinicalTrials. gov, NCT04812054). RESULTS: Of the 104 liver transplantations included in the study, 26 were assigned to HOPE and 78 to SCS. Mean MEAF was 4.94 and 5.49 in the HOPE and SCS groups ( P =0.24), respectively, with the corresponding rates of MEAF >8 of 3.8% (1/26) and 15.4% (12/78; P =0.18). Median Comprehensive Complication Index was 20.9 after transplantations with HOPE and 21.8 after transplantations with SCS ( P =0.19). Transaminase activity, bilirubin concentration, and international normalized ratio were similar in both groups. In the case of donor risk index >1.70, HOPE was associated with significantly lower mean MEAF (4.92 vs 6.31; P =0.037) and lower median Comprehensive Complication Index (4.35 vs 22.6; P =0.050). No significant differences between HOPE and SCS were observed for lower donor risk index values. CONCLUSION: Routine use of HOPE in DBD liver transplantations does not seem justified as the clinical benefits are limited to high-risk donors.

Liver Transplantation for Unresectable Calcifying Nested Stromal Epithelial Tumor: Case Report With a 1-Year Follow-Up and Review of Literature.

Introduction: Calcifying nested stromal epithelial tumor (CNSET) is an extremely rare diagnosis among patients treated for primary hepatic neoplasms. There are only 45 cases reported worldwide. Histopathological characteristics are well-demarcated nests of spindle and epithelioid cells in a dense desmoplastic stroma with variable calcification and ossification. It is mostly diagnosed in children and young females. Treatment strategies implemented for the management of CNSET include radiofrequency ablation, transarterial chemoembolization, surgical resection, adjuvant and neoadjuvant chemotherapy, and liver transplantation. Given the small number of available cases, there are still no established standards of treatment for this neoplasm. Case Presentation: A 28-year-old female diagnosed with CNSET presented mild abdominal pain, with normal laboratory values. The tumor was initially deemed unresectable, therefore, the patient was disqualified from liver resection. Further deterioration of the patient's clinical condition and local tumor progression led to qualification for liver transplantation. The patient underwent liver transplantation 1 year following initial diagnosis and a 12 months recurrence-free period was observed. During the course of treatment, she did not receive systemic chemotherapy, radiotherapy, or loco-regional treatment. Conclusion: Multiple strategies have been implemented for the treatment of CNSET, with liver resection providing the best outcomes. Transarterial chemoembolization, radiofrequency ablation, and radiotherapy are reported to be insufficient in the management of this tumor. Various chemotherapy regimens turned out to be ineffective as well. There have been only eight reported cases of patients undergoing liver transplantation for CNSET, with tumor recurrence in two cases. CNSET appears to be a neoplasm with low malignancy potential, although an aggressive progression has subsequently been reported. Further investigation is still required in this field.

Early results of the implementation of laparoscopic major liver resection program.

BACKGROUND: Laparoscopic liver resections offer potential benefits but may require advanced laparoscopic skills and are volume dependent. METHODS: This retrospective study included 12 patients who underwent major laparoscopic resection and 24 patients after open major liver resection for liver malignancy in the time period between September 2020 and May 2021. The primary outcomes were complications according to Clavien-Dindo classification and duration of hospital stay. RESULTS: Median duration of hospital stay in laparoscopic resection group (6 days) was significantly shorter than in open resection group (8 days) (p = 0.046). Complications classified as grade II or higher were significantly less frequent in the laparoscopic resection group (2 patients) versus open resection group (13 patients) (p = 0.031). CONCLUSIONS: Although laparoscopic major liver resections should be limited to expert hepatobiliary centers and are characterized by long learning curve, this approach may offer favorable short-term outcomes even during launching a new program.

Incisional Surgical Site Infections After Mass and Layered Closure of Upper Abdominal Transverse Incisions: First Results of a Randomized Controlled Trial.

OBJECTIVE: To compare the early results of mass and layered closure of upper abdominal transverse incisions. SUMMARY OF BACKGROUND DATA: Contrary to midline incisions, data on closure of transverse abdominal incisions are lacking. METHODS: This is the first analysis of a randomized controlled trial primarily designed to compare mass with layered closure of transverse incisions with respect to incisional hernias. Patients undergoing laparotomy through upper abdominal transverse incisions were randomized to either mass or layered closure with continuous sutures. Incisional surgical site infection (incisional-SSI) was the primary end-point. Secondary end-points comprised suture-to-wound length ratio (SWLR), closure duration, and fascial dehiscence (clinicatrials.gov NCT03561727). RESULTS: A total of 268 patients were randomized to either mass (n=134) or layered (n=134) closure. Incisional-SSIs occurred in 24 (17.9%) and 8 (6.0%) patients after mass and layered closure, respectively (P =0.004), with crude odds ratio (OR) of 0.29 [95% confidence interval (95% CI) 0.13-0.67; P =0.004]. Layered technique was independently associated with fewer incisional-SSIs (OR: 0.29; 95% CI 0.12-0.69; P =0.005). The number needed to treat, absolute, and relative risk reduction for layered technique in reducing incisional-SSIs were 8.4 patients, 11.9%, and 66.5%, respectively. Dehiscence occurred in one (0.8%) patient after layered closure and in two (1.5%) patients after mass closure (P >0.999). Median SWLR were 8.1 and 5.6 (P <0.001) with median closure times of 27.5 and 25.0 minutes (P =0.044) for layered and mass closures, respectively. CONCLUSIONS: Layered closure of upper abdominal transverse incisions should be preferred due to lower risk of incisional-SSIs and higher SWLR, despite clinically irrelevant longer duration.

Long-Term Health-Related Quality of Life in Living Liver Donors.

BACKGROUND In living donor liver transplantation (LDLT), 2 patients undergo surgery, and the advantages and disadvantages for both patients should be considered. This study evaluated the long-term quality of life in living liver donors, and its impact on their activities of daily living focusing on mood and mental health. MATERIAL AND METHODS In total, 101 living liver donors (69 female and 32 male patients, median age of 36.8 years) were surveyed at a median time of 61.8 months after liver donation (range 7-169 months). The generic Short Form Health Survey (SF-36), the Patient Health Questionnaire 9 (PHQ-9), and the Questionnaire of Physical Activity (IPAQ) were used. The results of SF-36 were compared to a matched control group (n=72) using the Wilcoxon test; the SF-36, the PHQ-9, and the IPAQ scores were analyzed using Spearman's rank correlation. Linear regression model was used to check for dependencies between variables of interest. The IPAQ results were compared between the study group and the general Polish population. RESULTS There were no significant differences in the SF-36 domains between the study group and control group except body pain, which was higher in the living liver donor group (P<0.05). In 30.6% of patients, the PHQ-9 survey revealed mood disturbances. The PHQ-9 scores were higher in female-donors (P<0.05). Both summary scores of the SF-36 correlated to the PHQ-9 (P<0.001). In 89.1% of patients, physical activity was below the population norm and was lower in female donors than in male donors (P<0.01). CONCLUSIONS LDLT had no impact on donors' physical and mental health. Physical activity of living liver donors was lower than that of the general population. The SF-36 and the IPAQ measures seem to be reliable in the care of living liver donors. The PHQ-9 survey results and the inclination to depression of female living liver donors requires further study.

Successful Hepatoatrial Anastomosis During a Consecutive Liver Retransplant in the Same Patient Shows Good Long-Term Results: Case Report and 2-Year Follow-Up.

Liver retransplant is the last and only treatment for patients with irreversible graft failure. It is recognized as a high-risk procedure; thus surgical difficulties are multiplied with every successive liver transplant. Liver retransplant is a demanding technical procedure for the surgeon, with no guarantee of postoperative and long-term survival. Here, we report a 29-year-old male patient who underwent a liver transplant in April 2009 due to primary sclerosing cholangitis with overlapping autoimmune hepatitis. The patient underwent liver retransplant in May 2012 due to graft failure. A second liver retransplant was performed in April 2013 using the classical technique. An inflammatory process involving the inferior vena cava and diaphragm forced the surgeon to open the pericardium from the diaphragm and clamp the cuff of the right atrium to perform a hepatoatrial anastomosis of the inferior vena cava. The next steps were performed as for a typical liver transplant. Postoperative stay was free of complications and was not prolonged. Immunosuppression regimen was kept standard. During our follow-up of more than 32 months, the patient continued to show good results. A consecutive hepatectomy in the same recipient is associated with an increased risk of intraoperative complications. When excessive adhesions limit a safe and functioning cavocaval anastomosis, a hepatectomy with the excision of the intrahepatic inferior vena cava and end-to-end anastomosis through a pericardial window for the extension of the recipient's' vena cava cuff are feasible options. We found that a hepatoatrial anastomosis does not impair good overall outcomes and long-term results.

Good outcome following liver transplantation using pericardial-peritoneum window for hepato-atrial anastomosis to overcome advanced hepatic alveolar echinococcosis and secondary Budd-Chiari Syndrome - a case report.

BACKGROUND: This report presents a case of a 57- year old female with advanced Hepatic Alveolar Echinococcosis causing a secondary Budd-Chiari Syndrome due to infiltration of the suprahepatic inferior vena cava treated successfully by liver transplantation. CASE PRESENTATION: A temporary veno-venous bypass was introduced, but a typical end to end cavo-caval anastomosis wasn't possible in this case. In order to access a disease free part of the inferior vena cava, an oval window of the diaphragm was excised, providing communication between the peritoneum and pericardium. A vascular clamp was placed onto the right atrium which allowed for an atrial-caval anastomosis. The remainder of hepatectomy was performed in a conventional manner. In the post-operative period and during the 18 month follow-up there were no complications. The patient remains in good general condition with optimal graft function. CONCLUSIONS: A hepato-atrial anastomosis with a pericardial-peritoneum window during liver transplantation is feasible and extends the curability potential for patients with advanced Hepatic Alveolar Echinococcosis considered for liver transplantation.

Expression of resistin in the liver of patients with non-alcoholic fatty liver disease.

Adipokines are cytokines that presumably connect the pathologies of metabolic syndrome. One of the adipokines is resistin, the role of which in insulin resistance, obesity, and non-alcoholic fatty liver disease (NAFLD) needs to be determined. Liver biopsy specimens were obtained intraoperatively from 214 obese patients. Histological assessment was based on NAFLD activity score according to Kleiner. Statistical analysis involved semi-quantitive immunohistochemistry assessment of resistin staining and: NAFLD status in obese patients compared with a non-obese control group, selected clinical data (age, sex, body mass index - BMI), selected biochemical data, comorbidities (hypertension, type 2 diabetes mellitus, dyslipidaemia), and metformin treatment in patients with type 2 diabetes mellitus. Resistin expression was observed in the histiocytes of inflammatory infiltrate, Kupffer cells, and histiocytes surrounding the hepatocytes with steatosis. There was a positive correlation between the total expression of resistin and: (1) NAFLD advancement (NAFLD Activity Score- NAS), (2) AST, ALT, BMI, glucose, insulin, Homeostasis Model Assessment (HOMA), LDH, GGT, triglycerides (TG), and glycated haemoglobin (HbA1c). Resistin expression was more intense in patients with type 2 diabetes mellitus and dyslipidaemia and less intense in the control group. Resistin probably plays a role in the pathogenesis of hepatic insulin resistance and aggravates pathologic changes in the liver of patients with NAFLD.

Is there a rationale for aggressive breast cancer liver metastases resections in Polish female patients? Analysis of overall survival following hepatic resection at a single centre in Poland.

INTRODUCTION: Breast cancer (BC) makes up nearly 26% of malignant tumours worldwide and is the leading cause of cancer-related deaths in European women. With approximately 18,000 new cases of BC diagnosed in Polish women annually, breast cancer liver metastasis (BCLM) is respectively an increasing issue. Recent data found in literature indicates improved survival following liver resection with systemic therapy. OBJECTIVE: The aim of study was to evaluate surgical treatment in patients with isolated BCLM. MATERIALS AND METHOD: During 2009-2013, a retrospective study was undertaken and 30 cases analysed. From nearly 2,000 liver resections performed, 11 female patients at the mean age of 59.18 years with BCLM were qualified for surgery. RESULTS: The median time between primary and secondary treatment was 3.5 years (1-7). One patient (9.1%) presented an extrahepatic lesion - bone metastasis. The left lobe, right lobe and both lobes of the liver were affected, respectively, in 3 (27.3%), 4 (36.4%) and 4 (36.4%) patients. 5 patients (45.5%) presented single hepatic lesion, in contrast to the maximum number of lesions which equalled 6 in the right lobe. Average hospitalisation period was 13.27 days and discharge on the 11.3 postoperative day. One-year survival was 72.7% (8 patients); therefore, three-year survival was 36.4% (4 patients). CONCLUSIONS: Oncological centres should assess BCLM patients more openly and qualify them for hepatic resection along with adjuvant systemic treatment in order to improve overall survival. This, however, needs to be studied in a multicentre randomized trial.

Surgical treatment of GERD. Comperative study of WTP vs. Toupet fundoplication - results of 151 consecutive cases.

INTRODUCTION: Gastroesophageal reflux disease (GERD) is recognized as one of the most common disorders of the upper gastrointestinal tract (GIT). The best choice of management for advanced GERD is laparoscopic surgery. AIM: To compare and evaluate the results of surgical treatment of GERD patients operated on using two different techniques. MATERIAL AND METHODS: Between 2001 and 2012, 353 patients (211 female and 142 male), aged 17-76 years (mean 44), underwent laparoscopic antireflux surgery. The study included patients who underwent a Toupet fundoplication or Wroblewski Tadeusz procedure (WTP). RESULTS: The mean age of the group was 47.77 years (17-80 years). Forty-nine (32.45%) patients had severe symptoms, 93 (61.58%) had mild symptoms and 9 (5.96%) had a single mild but intolerable sign of GERD. Eighty-six (56.95%) patients had a Toupet fundoplication and 65 (43.04%) had a WTP. The follow-up period was 18-144 months. The average operating time for Toupet fundoplication and the WTP procedure was 164 min (90-300 min) and 147 min (90-210 min), respectively. The perioperative mortality rate was 0.66%. The average post-operative hospitalization period was 5.4 days (2-16 post-operative days (POD) = Toupet) vs. 4.7 days (2-9 POD = WTP). No reoperations were performed. No major surgical complications were identified. CONCLUSIONS: Wroblewski Tadeusz procedure due to a low percentage of post-operative complications, good quality of life of patients and a zero recurrence rate of hiatal hernia should be a method of choice.

Intraoperative salvage endoscopy performed during orthotopic liver transplantation due to esophageal bleeding.

INTRODUCTION: Liver transplantation (LTx) is a widely accepted method of treatment for end stage liver diseases. There are many reports on the management of gastrointestinal bleeding (GIB) after LTx, however the number of studies concerning salvage endoscopic procedures during LTx are scarce. AIM: We present our material of intraoperative endoscopic procedures due to GIB during LTx. MATERIAL AND METHODS: During this period there were 4 females and 1 male at the mean age of 52.2 (35-65) years who underwent LTx and 1 patient had Re-LTx. All patients were Child-Pugh group C and mean MELD score was 17.75. Esophageal and/or gastric varices were present before surgery in all patients but only 1 female patient didn't experience GIB prior to LTx. Variables such as operating time, cold ischemic time, blood loss, blood transfusion, PLT count, international normalized ratio, albumin levels were similar in all patients thus making it statistically insignificant as the cause of GIB. RESULTS: In all cases a single IOE was necessary and bleeding from ruptured varices succumbed to endoscopic ligation. In 2 patients besides trials of ligating the varix, histoacryl was put in use which proved success. In both these last female patients the endoscopic physician had to insert a Danis stent. A follow up endoscopy was performed on the 7-10 POD. CONCLUSIONS: Intra-operative endoscopy performed during LTx does not interrupt surgery. Performed as soon as possible results in less future endoscopic interventions due to GIB. Intraoperative endoscopy may be considered as a salvage procedure and should be performed in the shortest possible time.

Transarterial Chemoembolization Prior to Liver Transplantation in Patients with Hepatocellular Carcinoma.

BACKGROUND: Transarterial chemoembolization (TACE) induces ischemic tumor necrosis, which is intensified by regional chemotherapy. By reducing the active tumor tissue, it can be assumed that patients on the waiting list for liver transplantation may benefit from this locoregional treatment. The aim of this study was to assess the relevance of TACE in hepatocellular carcinoma (HCC) patients before liver transplantation. MATERIAL AND METHODS: A retrospective analysis was performed on data of 229 patients who were transplanted for HCC. A group of 75 patients were treated with TACE prior to liver transplantation. Tumor necrosis related to pretransplantation locoregional treatment was assessed in an explanted liver and classified into extensive (51-100%), moderate (26-50%) and limited (<25%) grades. Five-year recurrence-free survival was estimated using the Kaplan-Meier method and compared using the log-rank test. RESULTS: In total, 143 HCC lesions were treated with TACE. Extensive necrosis was found in 63 (44.0%) tumors. Moderate and limited necrosis were observed in 42 (29.4%) and 38 (26.6%) tumors, respectively. In 36 (58.1%) explanted livers, every tumor was classified as extensively necrotic. The 5-year recurrence-free survival was estimated as 81.6% in the group not treated with TACE prior to liver transplantation (TACE-) and as 73.1% in the TACE+ group (p=0.169). Among patients not fulfilling the Milan criteria, 5-year recurrence-free survival was 63.1% in TACE- and 65.1% in TACE+ (p=0.656). CONCLUSIONS: In conclusion, TACE prior to liver transplantation is effective in inducing tumor necrosis. However, evidence of benefits in long-term results after liver transplantation requires further confirmation.

Acetaminophen (Paracetamol) induced acute liver failure - A social problem in an era of increasing tendency to self-treatment.

INTRODUCTION: The widespread availability of medication without prescription, so-called over the counter (OTC), and the rapid development of health consciousness of Poles is associated with broad access to medical information in the mass media. This causes patients to recognize their own disease, cancel doctor's appointments, and begin self-treatment. This time and money-saving behavior, often signaled by pain, usually leads to the treatment of symptoms alone, without seeking the cause of the disease.The aim of the study was to present life-threatening paracetamol poisoning, and the treatment of acute liver failure. MATERIAL AND METHODS: In 2002-2014, 35 patients were hospitalized due to acute paracetamol poisoning: 17 female and 18 male patients aged between 17-59 (mean 32.3 years). Patients were treated in the surgical intensive care unit, where their parameters of liver and renal function were continuously monitored. If there was no improvement in the liver function, patients underwent albumin dialysis with the Prometheus system and were qualified for liver transplantation (LTx). RESULTS: 26 patients were treated pharmacologically and 7 out of 9 patients who underwent LTx were dialyzed. Overall, 11 patients had 26 albumin dialysis in total; 4 patients died - 1 post-transplant and 3 pre-transplant. CONCLUSIONS: Paracetamol is the cause of many poisonings resulting from the lack of public awareness about toxic interactions with alcohol, and suicide attempts. Acetaminophen-induced acute liver failure concerns a small percentage of patients but can be successfully treated with albumin dialysis, and in extreme cases by liver transplantation.

Endoscopic Treatment of Early Biliary Complications in Liver Transplant Recipients.

BACKGROUND: The most common complications following liver transplantation (LTx) concern the biliary ducts. Potential early complications are biliary leaks and anastomotic strictures of the bile duct. The aim of this study was to evaluate the efficacy of endoscopic treatment of early biliary complications in liver transplant recipients after end-to-end biliary anastomosis. MATERIAL AND METHODS: From January 2011 to December 2013, 475 patients underwent LTx at our Department. There were 101 endoscopic procedures performed in total during this period, out of which 67 were related to biliary complications in 44 patients, while the remaining procedures were carried out due to gastrointestinal bleeding. We established a timeframe of up to 3 months postoperatively as the early biliary complication period. With the selected criteria we retrospectively analyzed medical records of 24 liver recipients who underwent endoscopic treatment due to early biliary complications. The outcome of endoscopic treatment was statistically analyzed and categorized as a technical and clinical success. RESULTS: During this period there were 38 endoscopic procedures in the analyzed group of patients treated due to early biliary complications. The results were: successful balloon dilation alone was performed in 2 patients with no further need of treatment, implantation of plastic stents was performed initially in 13 patients, but 7 patients required further stenting with larger caliber plastic stents (PS). Self-expandable metal stents (SEMS) were initially placed in 7 patients during this period overall. One patient was treated due to hemobilia. In 1 case endoscopic retrograde cholangiopancreatography (ERCP) was unfeasible and the patient required surgical intervention. In 1 case a PS was exchanged for an SEMS. Six patients with satisfactory cholangiography images had the stent removed during the second ERCP. CONCLUSIONS: In consideration of the stabilized rate of biliary complications following LTx, an advanced transplant center cannot function without an experienced endoscopist. For early biliary leaks and anastomotic strictures, ERCP is the primary treatment.

Surgical treatment of gall-bladder cancer.

Despite the aggressive nature and poor prognosis of gall-bladder cancer there is a group of patients who can achieve significant benefits from a radical surgical treatment. The possibility of obtaining long-term survival, even in case of patients with locally advanced cancer and metastases to regional lymph nodes, prompts to verify nihilistic approach to the treatment of this disease. Obviously such therapy can and should be performed only in centers specializing in hepatobiliary surgery. Due to the high recurrence rate, most of which are systemic, the hope of improving treatment outcomes should be sought in the use of combination therapy, based on a new chemotherapy and chemoradiotherapy regimens with the addition of targeted therapy. Unfortunately, the current application of these methods did not bring the expected benefits.

Minilaparoscopic cholecystectomy - the new non-visible scars technique. Preliminary report of first series.

INTRODUCTION: Surgery without scars is the dream of many patients and surgeons as well. It includes many new laparoscopic techniques (LESS, SILS, hybrid NOTES), but data concerning common bile duct (CBD) lesions are unavailable. AIM: To establish the new technique of minilaparoscopic cholecystectomy (MCh): non-visible scar intervention without increasing the risk of CBD lesions. MATERIAL AND METHODS: Forty consecutive patients with symptomatic gallbladder lithiasis were qualified for elective laparoscopic cholecystectomy (LCh) using one 10/11 mm umbilical port, one 5 mm right suprapubic port and two minilaparoscopic, disposable, no-port graspers. There were 26 women and 14 men, with the mean age 56 (17-72) years and with the average body mass index 28 (18-33) kg/m(2). CO2 Veress 15 mm Hg pneumoperitoneum was performed after transumbilical incision, and the first 10/11 mm port was inserted at the beginning for the 5 mm laparoscope and finally for typical instruments. Next under camera control, a 5 mm trocar was inserted in the right 'bikini line'. To this port the laparoscope was relocated from the umbilicus, and under its control two minilaparoscopic, disposable, non-port graspers were introduced after small, 2 mm skin incisions in the right anterior axillary line and in the right mesogastrium to catch the gallbladder. Next through the umbilical port, using typical instruments, the cystic duct and artery were dissected, clipped and cut. The gallbladder was removed through the umbilical port whole. RESULTS: There was no conversion to open cholecystectomy. In 5 cases drainage of the gallbladder lodge was necessary through a 5 mm port in the right bikini line. The time of the intervention ranged from 90 min during the introduction of the new method to 50 min for the last procedures. No postoperative complications were observed, and all patients were discharged at the same time as after conventional LCh. CONCLUSIONS: Two-port laparoscopic cholecystectomy performed with two minilaparoscopic no-port graspers does not increase the risk of CBD lesions. It provides an excellent cosmetic effect and is very convenient for the surgeon like typical LCh.

Multiple plastic stents for benign extrahepatic biliary strictures: report of a case.

The etiology of benign bile duct strictures is heterogeneous. Many of them may be secondary to intraoperative injury such as injuries occurring during laparoscopic cholecystectomy. The spectrum of symptoms at presentation varies from subclinical disease with elevation of liver function tests to complete biliary obstruction with jaundice and hyperbilirubinemia or external biliary fistula in the case of bile duct injury. Long-term consequences may lead to secondary biliary cirrhosis. This publication reports a case of a 49-year-old woman with symptomatic gallstone disease who underwent a laparoscopic cholecystectomy in November 2006. She underwent endoscopic retrograde cholangio-pancreatography due to jaundice, fever and abdominal pain. Then she underwent left hemi-hepatectomy in October 2008 and transplantation of the liver in January 2014. Traditionally, surgical repair has been the preferred approach in benign biliary strictures, but there is an increasing trend for use of minimally invasive endoscopic therapy in these patients.

Management of Giant Hepatic Hemangioma in Atypical Localization; Report of a Case and Literature Review.

Hemangiomas are the most common benign primary hepatic neoplasms, often being incidentally discovered. In most of the cases they are small and asymptomatic. It is widely accepted that clinical intervention is indicated only for symptomatic hemangiomas. We present a case of an asymptomatic giant hemangioma managed by enucleation due to its atypical localization. The hemangioma, originally located in segment 5, was now described in Computer Tomography (CT) Imaging as separating the gallbladder from the liver parenchyma. A careful evaluation of images revealed proximity to the portal vein (PV), right hepatic artery (RHA), right hepatic duct (RHD) and right branch of the portal vein (RBPV). Thus, in the case of an emergent operation, surgical maneuvers in the area of the altered hepatic anatomy and proximity to the hemangioma itself, would in fact increase the risk endangering the patient's life. After patient's consent, a surgical enucleation en block with the gall-bladder was performed. It is of great importance that specifically selected, asymptomatic patients diagnosed with a giant hemangioma, with the above mentioned or similar localization should be considered for surgical treatment.

Evolution Of The Results Of 1500 Liver Transplantations Performed In The Department Of General, Transplant And Liver Surgery Medical University Of Warsaw.

UNLABELLED: Liver transplantation is a well-established treatment of patients with end-stage liver disease and selected liver tumors. Remarkable progress has been made over the last years concerning nearly all of its aspects. The aim of this study was to evaluate the evolution of long-term outcomes after liver transplantations performed in the Department of General, Transplant and Liver Surgery (Medical University of Warsaw). MATERIAL AND METHODS: Data of 1500 liver transplantations performed between 1989 and 2014 were retrospectively analyzed. Transplantations were divided into 3 groups: group 1 including first 500 operations, group 2 including subsequent 500, and group 3 comprising the most recent 500. Five year overall and graft survival were set as outcome measures. RESULTS: Increased number of transplantations performed at the site was associated with increased age of the recipients (p<0.001) and donors (p<0.001), increased rate of male recipients (p<0.001), and increased rate of piggyback operations (p<0.001), and decreased MELD (p<0.001), as well as decreased blood (p=0.006) and plasma (p<0.001) transfusions. Overall survival was 71.6% at 5 years in group 1, 74.5% at 5 years in group 2, and 85% at 2.9 years in group 3 (p=0.008). Improvement of overall survival was particularly observed for primary transplantations (p=0.004). Increased graft survival rates did not reach the level of significance (p=0.136). CONCLUSIONS: Long-term outcomes after liver transplantations performed in the Department of General, Transplant and Liver Surgery are comparable to those achieved in the largest transplant centers worldwide and are continuously improving despite increasing recipient age and wider utilization of organs procured from older donors.

Endoscopic treatment of gastric varices bleeding with the use of n-butyl-2 cyanoacrylate.

INTRODUCTION: Oesophageal varices and gastric varices are naturally-formed, pathological portosystemic shunts that occur in patients with portal hypertension. Gastric varices are responsible for about 10% of variceal bleeding; however, they are also the cause of massive haemorrhage, often with dramatic progress. AIM: To assess the results of endoscopic treatment of gastrointestinal bleeding from oesophageal and gastric varices using tissue glue Histoacryl. MATERIAL AND METHODS: From January 2013 to May 2015 170 patients underwent a total of 244 obliterations with the administration of tissue glue due to gastroesophageal varices. We analysed 35 patients who received urgent endoscopic intervention due to life-threatening gastric variceal bleeding. RESULTS: Thirty-five patients underwent 47 endoscopic procedures of haemorrhage management. Immediate haemostasis was achieved in 32 (91.4%) patients. In 3 (8.6%) cases endoscopy failed. In 2 patients a Linton tube was applied before secondary endoscopy. A single trans jugular portosystemic shunt (TIPS) was performed. Permanent haemostasis during the first endoscopy was achieved in 26 (74%) patients. Six (17%) patients presented recurrent bleeding 1-4 days following the initial treatment. Three patients had a splenic artery embolisation performed. One of the embolised patients required surgery, and a splenectomy was carried out. CONCLUSIONS: If this kind of therapy is unavailable at the time, it is advised that one of the conventional methods of controlling bleeding is used, introducing basic life support and transporting the patient to a specialist centre with adequate endoscopic facilities, radiological possibilities of endovascular intervention, and surgical treatment of liver transplantation.
