Opis:
The aim of the study was to present early outcomes of liver resection using laparoscopic technique. Material and methods. Retrospective analysis of patients who underwent liver resection using laparoscopic method was conducted. The analyzed group included 23 patients (11 women and 12 men). An average patient age was 61.3 years (37 – 83 years). Metastases of the colorectal cancer to the liver were the cause for qualification to the procedure of 15 patients, metastasis of breast cancer in 1 patient and primary liver malignancy in 5 patients. The other 2 patients were qualified to the liver resection to widen the surgical margins due to gall-bladder cancer diagnosed in the pathological assessment of the specimen resected during laparoscopic cholecystectomy, initially performed for other than oncology indications. Results. Hemihepatectomy was performed in 11 patients (9 right and 2 left), while the other 12 patients underwent minor resection procedures (5 metastasectomies, 4 nonanatomical liver resections, 1 bisegmentectomy, 2 resections of the gall-bladder fossa). An average duration of the surgical procedure was 275 minutes 65 – 600). An average size of the resected tumors was 28 mm (7 – 55 mm). In three cases conversion to laparotomy occurred, caused by excessive bleeding from the liver parenchyma. Postoperative complications were found in 4 patients (17.4%). Median hospitalization duration was 6 days (2 – 130 days). One patient (4.3%) was rehospitalized due to subhepatic abscess and required reoperation. Histopathology assessment confirmed radical resection (R0) in all patients in our group. Conclusion. Laparoscopic liver resections seem to be an interesting alternative in the treatment of focal lesions in the liver.

Opis:
Experimental research on liver transplantation was introduced in Poland by Waldemar Olszewski and his team in 1972. Not until 15 years later, in 1987, did Stanisław Zieliński in Szczecin and Marian Pardela in Katowice make an attempt of transplanting liver in humans. In 1989 another attempt was made by Jacek Pawlak and Marek Krawczyk in Warsaw. The first successful liver transplantation in Poland was performed in 1990 by Piotr Kaliciński at the Children’s Memorial Health Institute, Warsaw. Also, in early 1990s the attempts were made by Jerzy Polański in Warsaw and Piotr Szyber in Wrocław. In the next years, liver transplantations were connected with three centers in Szczecin and were associated with the following persons: Roman Kostryka, Maciej Wójcicki and Samir Zeaira. In Warsaw, 1994, Jacek Pawlak, Bogdan Michałowicz and Krzysztof Zieniewicz performed another successful liver transplantation. The program started to develop rapidly and is still up and running. In 2000, Wojciech Rowiński and Marek 
Pacholczyk created another liver transplant center in Warsaw, while in 2005 Lech Cierpka and Robert Król did the same in Katowice. In the following years, liver transplantation was initiated by Maciej Słupski in Bydgoszcz (2017) and Zbigniew Śledziński in Gdańsk (2018). In the developing liver transplant centers, an exceptional contribution was made by Paweł Nyckowski, Jacek Pawlak, Krzysztof Zieniewicz, Waldemar Patkowski, Tadeusz Wróblewski, Rafał Paluszkiewicz, Marek Pacholczyk, Andrzej Chmura, Maciej Kosieradzki and Marek Krawczyk – all employed by the Medical University of Warsaw. In Wrocław, Dariusz Patrzałek and Paweł Chudoba were very active in the field of liver transplantations. In 1996, the Organizing-Coordinating Center for Transplantation POLTRANSPLANT was brought to life and at first was directed by Janusz Wałaszewski, then by Roman Danielewicz and Artur Kamiński. In 1999, Piotr Kaliciński and Marek Krawczyk started the program for liver fragment harvesting and transplantation from living donors. Until the end of 2016, 4186 liver transplantations including 314 liver transplants from living donors were performed in Poland. Currently there are three active centres in Warsaw, namely Pediatric Surgery and Transplantation Surgery, Children’s Memorial Health Institute; Department of General, Transplant and Liver Surgery, Medical University of Warsaw; 
Department of General and Transplant Surgery, Medical University of Warsaw. Other active centres in Poland are Department of General and Transplant Surgery, Provincial Hospital in Szczecin, Department of General, Vascular and Transplant Surgery, Medical University of Silesia, Katowice, Department of Vascular, General and Transplant Surgery in Wrocław. Liver transplant programs have also been initiated at the Department of Liver and General Surgery, Bydgoszcz, and Department of General, Endocrine and Transplant Surgery, Medical University of Gdańsk.

Opis:
Liver is the most common location of the colorectal cancer metastases occurrence. Liver resection is the only curative method of treatment. Unfortunately it is feasible only in 25% of patients with colorectal liver metastases, often because of the extensiveness of the disease. The aim of the study was to evaluate the predictive value of total tumor volume, size and number of colorectal liver metastases in patients treated with right hemihepatectomy. Material and methods. A retrospective analysis was performed in a group of 135 patients with colorectal liver metastases, who were treated with right hemihepatectomy. Total tumor volume was estimated based on the formula (4/3)πr3. Moreover, the study included an analysis of data on the number and size of tumors, radicality of the resection, time between primary tumor resection and liver resection, pre-operative blood serum concentration of carcinoembryonal antigen (CEA) and carcinoma antigen Ca19-9. The predictive value of the factors was evaluated by applying a Cox proportional hazards model and the area under the ROC curve. Results. The univariate analysis has shown the predictive value of size of the largest tumor (p=0.033; HR=1.065 per each cm) on the overall survival, however no predictive value of number of tumors (p=0.997; HR=1.000) and total tumor volume (p=0.212; HR=1.002) was observed. The multivariate analysis did not confirm the predictive value of the size of the largest tumor (p=0.141; HR=1.056). In the analysis of ROC curves, AUROC for the total tumor volume, the size of the largest tumor and the number of tumors were 0.629, 0.608, 0.520, respectively. Conclusions. Total tumor volume, size and number of liver metastases are not independent risk factors for the worse overall survival of patients with colorectal liver metastases treated with liver resection, therefore increased values of these factors should not be a contraindication for surgical treatment

Opis:
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.

Opis:
Background: Gallstone disease (GSD) and nonalcoholic fatty liver disease (NAFLD) are connected with a high prevalence in the general population and they share common risk factors for their occurrence. Limited literature with inconsistent results is available, suggesting a potential association between these lifestyle-induced diseases. Liver biopsy is the gold standard for diagnosing NAFLD. The aim of this study was (1) to identify the prevalence of asymptomatic NAFLD or NASH in liver biopsy; (2) to identify the association of hypercholesterolemia with NAFLD in patients undergoing laparoscopic cholecystectomy (LC). Methods: This is a prospective observational study conducted on patients who underwent LC for symptomatic gallstones in the Department of General Surgery, Post Graduate Institute of Medical Education and Research, Chandigarh, India, from 1st July 2013 to 31st December 2014. All included patients had ultrasonography (USG) and the following parameters tested: serum triglycerides (TG), cholesterol, low density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C). A wedge liver biopsy was obtained from free edge of the right liver lobe during LC and all biopsy specimens were analyzed by a single pathologist. Results: Among 101 patients included in the study, dyslipidemia was present in 49.50%. There was no association between NAFLD and serum cholesterol, TG or LDL-C (P, 0.428, 0.848, 0.371 respectively). NAFLD was confirmed in liver biopsy in 21.8% of patients but none had fibrosis or cirrhosis on biopsy. No complications were observed following liver biopsy. Conclusions: Liver biopsy during LC gives an opportunity to diagnose the disease at an early and reversible stage. It is feasible, safe and cost effective.

Opis:
Liver resection is essential part of colorectal cancer liver metastases (CLM) treatment. Mean 5-year overall survival after resection achieves 30-45%. There are many factors influencing long-term outcomes, and among them the inflammatory response to tumor plays an important role. The aim of the study was evaluation of outcomes and treatment safety of patients with metastatic colorectal cancer to the liver with estimation of prognostic factors. Material and methods. 130 consecutive patients (70 men and 60 women) operated in MSC Institute and Cancer Center in Gliwice from 2001 to 2009 due to colorectal liver metastases were analysed. Age of the patients ranged from 33 to 82 years (median 60 years). 96 (74%) patients underwent potentially radical resection, and in remaining 34 (26%) was performed radiofrequency ablation (RFA) alone or combined with the resection. In the resection group 37 right hepatectomies, 11 left hepatectomies, 28 segmentectomies and 20 metastasectomies were performed. Disease-free survival (DFS) and overall survival (OS) were statistically analysed using the Kaplan-Meier method. Factors determining DFS and OS were analysed using Cox regression model. Results. In the resection group the 3- and 5-years OS was 64,5% and 46,6% respectively, and the 3- and 5-years DFS was 32% and 30,5% respectively. In the RFA group the 3- and 5-years OS was 33% and 9,5%. Statistically significant prognostic factors in the resection group in uni- and multivariate analysis were: grade and nodal involvement of the primary tumor, diameter of metastatic focus, positive and narrow (<1 mm) resection margins, preoperative fibrinogen level, preoperative neutrophil to lymphocyte ratio and leukocyte amount of the peripheral blood. The perioperative mortality rate was 3%. Conclusions. Liver resection due to colorectal liver metastases is a safe and effective method resulting in high survival rates. We confirmed some generally accepted prognostic factors influencing longterm outcomes and shown the impact of inflammatory response. We also confirmed the hypothesis that preoperative plasma fibrinogen level influences outcomes after liver resection due to CLM.

The aim of the study was to analyze indications and results of the first one thousand liver transplantations at Chair and Clinic of General, Transplantation and Liver Surgery, Medical University of Warsaw.Material and methods. Data from 1000 transplantations (944 patients) performed at Chair and Clinic of General, Transplantation and Liver Surgery between 1994 and 2011 were analyzed retrospectively. These included 943 first transplantations and 55 retransplantations and 2 re-retransplantations. Frequency of particular indications for first transplantation and retransplantations was established. Perioperative mortality was defined as death within 30 days after the transplantation. Kaplan-Meier survival analysis was used to estimate 5-year patient and graft survival.Results. The most common indications for first transplantation included: liver failure caused by hepatitis C infection (27.8%) and hepatitis B infection (18%) and alcoholic liver disease (17.7%). Early (< 6 months) and late (> 6 months) retransplantations were dominated by hepatic artery thrombosis (54.3%) and recurrence of the underlying disease (45%). Perioperative mortality rate was 8.9% for first transplantations and 34.5% for retransplantations. Five-year patient and graft survival rate was 74.3% and 71%, respectively, after first transplantations and 54.7% and 52.9%, respectively, after retransplantations.Conclusions. Development of liver transplantation program provided more than 1000 transplantations and excellent long-term results. Liver failure caused by hepatitis C and B infections remains the most common cause of liver transplantation and structure of other indications is consistent with European data.

Opis:
The quality of liver assessment in an oncological patient plays an important role in the selection of a proper type of medical intervention. Diagnostic techniques commonly used in liver imaging are still far from perfect. Intraoperative liver evaluation using an intraabdominal ultrasound probe remains an important tool for proper assessment of this organ. The aim of the study was to evaluate suitability of this intraoperative diagnostic method for detection of primary and secondary neoplastic pathologies of the liver. Material and methods. Between March 2010 and the end of December 2011, we performed intraoperative ultrasound examinations of the liver during 220 of 461 laparotomies carried out for oncological reasons. Results. In 72 patients (33%), intraoperative ultrasonography using an intraabdominal probe revealed neoplastic pathologies in the liver. In 16 patients (7%), the pathologies had not been observed in the preoperative imaging examinations. In 7 cases (3%), the detected tumors were impalpable and invisible in macroscopic examination routinely performed during laparotomy. The time of performing preoperative liver examinations did not affect the detection of previously unrecognized liver tumors (p > 0.05). We found progression in the number of liver tumors in 28 patients (39%). In 20 patients (9%), the primary surgical plans were changed intraoperatively. Conclusions. Liver examination using an intraabdominal ultrasound probe is a useful tool for assessment of neoplastic disease progression. The procedure allows proper choice of an optimal treatment regime and decreases the risk of performing an unnecessary oncological invasive procedure.

Introduction: Resection is an optimal way of treatment of hepatic tumors and metastasis from another organs. Operational injury may influence on patients body composition examined by bioelectrical impedance (BIA). Analysis of parameters may be helpful in identifying early changes indicating of deterioration in nutritional status. Aim of the study: was to assess changes in body composition of patients before and after resection of liver tumors and potential radiofrequency ablation of lesions. Material and methods: The study included a group of 50 patients of the Department of General, Gastroenterological and Oncological Surgery, Medical University of Warsaw, who were qualified for radical surgical treatment of tumors within the liver. Data on water content, fat, muscle and cell mass were analyzed. Results: Comparing data obtained from patients before and after intervention in the liver, statistically significant (p < 0.05) loss of intracellular water, muscle mass, cell mass as well as adipose tissue was demonstrated. The phase angle value in these patients also significantly changed, decreasing by an average of 0.61°. On the other hand, the increase in content was noted in the case of extracellular water. Conclusions: Surgical intervention within the liver causes noticeable, unfavorable changes in the body composition, as evidenced by the reduction in the value of muscle mass, as well as cellular mass, resulting in a decrease in the phase angle. Bioelectric impedance is a suitable method for assessing changes in body composition of patients undergoing liver resection and is useful in clinical practice. It is advisable to conduct further research in the group of patients undergoing invasive treatment of the liver due to: an increasing number of such operations and centers where this type of surgical intervention is performe.

Intraabdominal hemorrhage remains one of the most frequent surgical complications after liver transplantation. The aim of the study was to evaluate risk factors for intraabdominal bleeding requiring reoperation and to assess the relevance of the reoperations with respect to short- and long-term outcomes following liver transplantation. Material and methods. Data of 603 liver transplantations performed in the Department of General, Transplant and Liver Surgery in the period between January 2011 and September 2014 were analyzed retrospectively. Study end-points comprised: reoperation due to bleeding and death during the first 90 postoperative days and between 90 postoperative day and third post-transplant year. Results. Reoperations for intraabdominal bleeding were performed after 45 out of 603 (7.5%) transplantations. Low pre-transplant hemoglobin was the only independent predictor of reoperation (p=0.002) with the cut-off of 11.3 g/dl. Postoperative 90-day mortality was significantly higher in patients undergoing reoperation as compared to the remaining patients (15.6% vs 5.6%, p=0.008). Post-transplant survival from 90 days to 3 years was non-significantly lower in patients after reoperation for bleeding (83.3%) as compared to the remaining patients (92.2%, p=0.096). Nevertheless, multivariable analyses did not reveal any significant negative impact of reoperations for bleeding on short-term mortality (p=0.589) and 3-year survival (p=0.079). Conclusions. Surgical interventions due to postoperative intraabdominal hemorrhage do not appear to affect short- and long-term outcomes following liver transplantation. Preoperative hemoglobin concentration over 11.3 g/dl is associated with decreased risk of this complication, yet the clinical relevance of this phenomenon is doubtful.

The aim of the study was to evaluate the possibility to use live anesthetized pigs as a model for laparoscopic liver resection. During two days laparoscopy course two trainees were operating on two live animals performing exposure of the liver, Pringle manoeuver, division of liver ligaments, dissecting of the structures inside the hepatoduodenal ligament, dissection of the hepatic veins and left lateral liver sectionectomy. Exposure of the liver and Pringle manoeuver were performed correctly within 50 and 35 minutes. Left lateral sectionectomy has been performed correctly within 2 hours. The full dissection of the hepatoduodenal ligament and exposure of the hepatic veins were judged as insufficient by experienced laparoscopic tutors. There was one injury to the suprahepatic vena cava that was managed laparoscopically. The porcine model can be used as an advanced training for laparoscopic liver surgery.

Opis:
Background: Liver metastases of differentiated thyroid cancers (DTC) are uncommon. Surgery has proven to be effective in patients with 131I-negative hepatic lesions. Here, we present two patients who underwent liver resection for metastatic DTC. Case presentation: The first patient is a 36-year-old woman who reported with 70-mm hepatic metastases of papillary thyroid cancer. After primary treatment of cancer, she was disease-free for 8 years when the elevation of TSH levels resulted for the need to search for metastasis. Notably, the 131I SPECT did not show any lesions. The CT scan revealed an 80mm diameter mass in the liver. Histology confirmed metastasis of thyroid cancer. Lack of iodine uptake and the size of lesion excluded treatment with radioactive iodine. Radical resection of the metastasis was performed with good short- and long-term postoperative result. The second patient is a 65-year-old man previously treated for follicular thyroid cancer. When a iodine-negative 70mm diameter metastasis was detected within the liver, he was referred for surgery. Extended right hepatectomy was performed. In a 12-months follow-up, he remained stable, with no signs of recurrence. Conclusions: These two cases show that resection of hepatic metastases of DTC is an option even in the case of large lesions. Given the effectiveness and safety of liver surgery, we reckon that it should be the treatment of choice when possible. The decision to perform surgical treatment should be based on analysis of the ability to perform radical and safe resection.

Opis:
This study presented a septic shock occurring with striking speed during the percutaneous drainage of a large abscess of the liver in an 18-year-old female patient after an appendectomy performed 3 months earlier using the laparoscopic method because of its phlegmonous and gangraenosus inflammation. The post-operative course was complicated by increased suppuration in places after removal of the trocars. After including the intravenous antibiotic therapy and under the USG control, the percutaneous drainage of the abscess was performed. While withdrawing the guide of the drainage catheter set, the symptoms of septic shock occurred. The pharmacological treatment was applied with continuation of the antibiotic therapy till a negative result of microbiological tests was obtained and the normalization of life parameters. The patient was not qualified for treatment in the ICU. She was discharged in a generally good condition after 24 days of hospitalization. In the case of this patient, the drain covered with the content of the abscess may have contact with the adjacent tiny blood vessels, which may have contributed to the systemic inflammatory response syndrome that was linked with fast-developing sceptic shock.

Opis:
Introduction: Bleeding from esophageal varices is a serious clinical condition in hemophilia patients due to congenital deficiency or lack of clotting factors VIII (in hemophilia A) and IX (in hemophilia B), decreased clotting factor II, VII, IX, X synthesis in the course of chronic liver disease and hipersplenic thrombocytopenia. The aim of this study was to assess the efficacy and safety of endoscopic sclerotherapy in acute esophageal variceal bleeding and in secondary prophylaxis of hemorrhage. The aim was also to investigate the optimal activity of deficiency factors VIII or IX and duration of replacement therapy required to ensure proper hemostasis after sclerotherapy procedures. Material and methods: 22 hemophilia patients (A-19, B-4) with coexistent liver cirrhosis and active esophageal variceal bleeding treated with endoscopic sclerotherapy were subjected to prospective analysis. The patients who survived were qualified to repeated sclerotherapy procedures every 3 weeks within secondary prophylaxis of bleeding (investigated group). A 3-day substitution therapy enhanced the infusion of the deficient or lacking factor in doses allowing to reach 80-100% of normal value activity of factor VIII on the 1st day and 60-80% in the next two days. The desired activity of factor IX was 60-80% and 40-60% respectively. The control group consisted of 20 non-hemophiliac patients with liver cirrhosis comparable in terms of age, sex, stage of advancement of liver cirrhosis, who underwent the same medical proceedings as the investigated group. Results: Active esophageal bleeding was stopped in 21 of 22 (95%) hemophilia patients. Complications were observed in 3 patients; 2 patients died. The rate of hemostasis, complications and deaths in the control group were comparable and no statistical differences were found. In hemophilia patients subjected to secondary prophylaxis of hemorrhage, in 18 of 20 (80%), complete eradication of esophageal varices was achieved after 4 to 7 sclerotherapy procedures in 1 patient (average 5.4). Recurrent bleeding was observed in 15% of patients, complication in 20%; 1 patient died. Time lapse from bleeding to eradication was 12-21 weeks (average 15.2). In the control group the rate of variceal eradication, complication and deaths was comparable and no statistical differences were found. The usage of factor VIII concentrates was as follows: in hemophilia A, in a severe form - 80.9 U/kg b.w./day, in hemophilia A in a severe form with an inhibitor <5 BU – 95.2 U/kg b.w./day, in mild form – 64.2 U/kg b.w./day and in severe hemophilia B – 91.6 U/kg b.w./day. Conclusions: Sclerotherapy is an effective method in the management of esophageal variceal bleeding in hemophilia patients. It is also effective for total eradication of varices when applied as a secondary prophylaxis of hemorrhage. In our opinion, a 3-day replacement therapy at the applied doses is sufficient to ensure hemostasis and avoid bleeding complications.

Opis:
The authors present the case of a female patient with a tumor of segment VII of the liver, which was postoperatively identified as a tuberculous granuloma. The patient was admitted for elective surgery for a liver tumor, which had been diagnosed a few months before. Computed tomography and nuclear magnetic resonance were performed, based on which focal nodular hyperplasia was suspected. Thirteen years prior to admission the patient had undergone a transurethral resection of superficial bladder carcinoma, followed by adjuvant intravesical Bacillus Calmette-Guérin (BCG-therapy). Upon surgery, segment VII of the liver was resected; postoperative course was uneventful. After the identification of granuloma, the patient was referred to a phthysiatric clinic for further diagnostics and treatment. The authors have deemed this case worthy of reporting primarily due to the exceptionally long period between the completion of BCG therapy and the onset of hepatic tumor.
