The impact of obesity on the outcome of severe SARS-CoV-2 ARDS in a high volume ECMO centre: ECMO and corticosteroids support the obesity paradox.

PURPOSE: The aim was to verify the impact of obesity on the long-term outcome of patients with severe SARS-CoV-2 ARDS. MATERIALS AND METHODS: The retrospective study included patients admitted to the high-volume ECMO centre between March 2020 and March 2022. The impact of body mass index (BMI), co-morbidities and therapeutic measures on the short and 90-day outcomes was analysed. RESULTS: 292 patients were included, of whom 119(40.8%) were treated with veno-venous ECMO cannulated mostly (73%) in a local hospital. 58.5% were obese (64.7% on ECMO), the ECMO was most frequent in BMI > 40(49%). The ICU mortality (36.8% for obese vs 33.9% for the non-obese, p = 0.58) was related to ECMO only for the non-obese (p = 0.04). The 90-day mortalities (48.5% obese vs 45.5% non-obese, p = 0.603) of the ECMO and non-ECMO patients were not significantly influenced by BMI (p = 0.47, p = 0.771, respectively). The obesity associated risk factors for adverse outcome were age <50 (RR 2.14) and history of chronic immunosuppressive therapy (RR 2.11, p = 0.009). The higher dosage of steroids (RR 0.57, p = 0.05) associated with a better outcome. CONCLUSIONS: The high incidence of obesity was not associated with worse short and long-term outcomes. ECMO in obese patients together with the use of steroids in the later stage of ARDS may improve survival.

Extrahepatic bile duct malignancies.

INTRODUCTION: Biliary tract malignancies belong to very aggressive malignancies of the gastrointestinal tract. The only radical treatment is surgical resection which is possible only in a limited number of cases due to late diagnosis. The aim of this report was to present the experience of our own department with the diagnosis and treatment of these tumours. METHODS: In the years 2005-2021 radical (R0) resection was performed in 27 (28.4%) patients, the same number were managed only symptomatically and in 41 (43.2%) patients we used biliary stenting and external-internal drainage as the definitive procedure. Adjuvant oncological treatment was indicated in 16 (59.3%) of the radically operated and 49 (72.1%) of the non-operated patients. RESULTS: Median overall survival and median progression-free survival in the operated patients were 19.9 months and 15.7 months, respectively. Overall survival in the operated patients was significantly better (p.

Radiofrequency ablation of colorectal liver metastases.

INTRODUCTION: Radical liver resection is the only method for the treatment of patients with colorectal liver metastases (CLM); however, only 20-30% of patients with CLMs can be radically treated. Radiofrequency ablation (RFA) is one of the possible methods of palliative treatment in such patients. METHODS: RFA was performed in 381 patients with CLMs between 01 Jan 2001 and 31 Dec 2018. The mean age of the patients was 65.2±8.7 years. The male to female ratio was 2:1. Open laparotomy was done in 238 (62.5%) patients and the CT-navigated transcutaneous approach was used in 143 (37.5%) patients. CLMs.

Therapy of liver cysts - experience of the Department of Surgery, University Hospital in Pilsen 20092018.

INTRODUCTION: Liver cysts are present in about 5% of the population and are asymptomatic in most cases. Currently, liver cystic lesions are disco-vered arbitrarily during imaging assessments of the abdomen indicated for unrelated reasons. The final findings vary from solitary cysts to multiple lesions or eventually the polycystic liver disease which can result in liver transplantation. Most cases are congenital. In the case of a symptomatic manifestation, pressure pain in the upper right quadrant is the predominant symptom. The therapy is surgical; laparoscopic approach is preferred. METHODS: A retrospective evaluation of the sample of 55 patients was conducted. The patients had been surgically treated at the Department of Surgery, University Hospital in Pilsen, from 01 Jan 2009 to 21 Dec 2017. The evaluation covered basic demographic data, the size of the dominant cyst, complications, hospitalization length, any relapse of the disease, etc. Results: In the presented period 62 surgeries of symptomatic liver cysts were performed, 55 of them by laparoscopy. The mean age of the patients was 61.7 years (32-83 years), women predominated (N=54, i.e. 87.1%). Complications occurred in 8 patients (12.9%); the most common was a bile leak. The mean length of hospitalisation was 4.5 days (2-20 days). In the follow-up period, 41 patients (66.1%) remained without any recidivism. CONCLUSION: Currently, the treatment of symptomatic liver cysts is laparoscopic, with fenestration being the standard approach. Due to potential complications centres with experience in liver surgery are prioritized.

Growth of colorectal liver metastases is not accelerated by intraportal administration of stem cells after portal vein embolization.

INTRODUCTION: Future liver remnant volume (FLRV) is a crucial factor impacting resectability of colorectal liver metastases (CLM). In case of low FLRV, augmentation can be done by performing portal vein embolization (PVE). However, there is a risk of progression of CLM between PVE and resection. Intraportal application of autologous hematopoietic stem cells (HSC) is a possibility to accelerate the growth of FLRV. The effect of thus applied SC on CLM progression still remains unclear, though. METHODS: 63 patients underwent PVE between 2003 and 2015. In 20 patients a product with HSC was applied intraportally on the first day after PVE (PVE HSC group). HSC were gained from peripheral blood (10 patients) or bone marrow (10 patients). FLRV and volume of liver metastases (VLM) were evaluated by CT volumetry. The gained data were statistically evaluated in relation to the disease free interval (DFI), overall survival (OS), achievement of CLM resectability and progression of extrahepatic metastases. We compared the PVE HSC group with the group of patient undergoing simple PVE. RESULTS: No significant difference in FLRV and VLM growth was observed between the study groups. The percentage of exploratory laparotomies was smaller in the group with PVE and HSC application. Patients with simple PVE had a significantly higher incidence of extrahepatic metastases during follow up. We did not observe any significant differences in DFI and OS between the groups. CONCLUSION: HSC application did not accelerate CLM growth in comparison with PVE alone. PVE and HSC application had a higher percentage of patients undergoing liver resection and a lower incidence of extrahepatic metastases.

[Use of viscoelastic methods in surgery]. / Vyuzití viskoelastických metod v chirurgii.

INTRODUCTION: Major liver resections are associated with high morbidity and mortality. The main causes of this fact include a significant blood loss which may be associated with this surgical procedure. Hemocoagulation disorder, diagnosed by standard laboratory tests, is very frequent in the postoperative period and often requires the administration of blood derivatives. Several recent studies, however, have questioned the presence of such coagulopathy when viscoelastic methods are used to assess the coagulation process. The studies have concluded that that the coagulation disorder only exists at a laboratory level, the coagulation process itself being unaffected, and no therapeutic intervention is therefore needed. The use of viscoelastic methods may play a crucial role in deciding whether or not to correct the assumed coagulation disorder. METHOD: Our study was designed as a prospective observational study. Data were collected in the Surgical Intensive Care Unit during one year (1 January - 31 December 2016). The study included 18 patients who underwent major liver resection. When coagulation disorder was diagnosed using standard coagulation tests in the postoperative period, we performed a ROTEM examination. The results of the standard and ROTEM examination were then compared. RESULTS: Out of the total of 18 patients enrolled in the study, a coagulopathy was diagnosed in 15 cases (83%) using standard coagulation tests. In these patients, we performed rotational tromboelastometry (ROTEM) which did not show any coagulation disorder. CONCLUSION: Our study has demonstrated that when viscoelastic methods are used to evaluate the function of blood clotting in patients after major hepatic surgery, no coagulopathy has been found as opposed to the evaluation with standard blood clotting tests. Unnecessary transfusions of blood derivatives can be avoided as well as all risks linked to their administration. Viscoelastic methods of coagulation assessment (ROTEM, TEG) help provide a detailed insight into the coagulation process and our observations have shown that they should play a significant role in the postoperative assessment of patients following major hepatic resections.Key words: ROTEM - viscoelastic methods - coagulopathy.

[Liver hemangiomas - when is invasive treatment indicated?] / Hemangiomy jater - kdy indikovat invazivní lécbu?

INTRODUCTION: Liver hemangiomas are the most common benign tumors of the liver. Most are asymptomatic and are found accidentally by ultrasonography, computed tomography or magnetic resonance imaging of the abdomen. Liver hemangiomas usually do not need any treatment. Nevertheless, symptomatic, giant hemangiomas can be indicated for surgery, embolization or thermoablation. The aim of this study was to define based on our own experience and on the literature when and what treatment option should be indicated in patients suffering from liver hemangioma. METHOD: In the last five years 37 patients with giant hemangiomas indicated for invasive treatment were enrolled in the study. The mean size of the hemangiomas was 67 mm (45-221 mm). Multiple hemangiomas were present in 11 (29.7%) patients. Enucleation was performed in 15 (40.5%), non-anatomical liver resection in three, (8.1%), left lobectomy in one (2.7%) and exploratory laparotomy for a suspected malignant liver tumor in two (5.4%) patients where malignancy was excluded based on contrast enhanced peroperative ultrasonography. Percutaneous transarterial embolization (TAE) was performed in 16 (43.2%) patients. RESULTS: There was zero mortality. A hematoma in the resection line, with spontaneous regression was present in two (10.5%) patients after the surgery. The post-embolization syndrome was presented in three (16.7%) patients after TAE. Progression of the hemangioma was seen in three (28.8%), regression in six (37.5%) patients, and in seven (43.8%) patients the finding remained stable in the interval of 14 years after TAE. CONCLUSION: Conservative approach is can be applied in most liver hemangiomas, especially in small, asymptomatic lesions. Liver surgery is indicated in giant symptomatic or growing hemangiomas with the diameter over 10 cm or in non-specific lesions where the preoperative diagnosis is uncertain. We recommend enucleation as the method of choice, or non-anatomic liver resection. TAE is indicated in high-risk patients and can be repeated if the hemangioma progresses. The use of other methods such as radiofrequency ablation needs to be verified in large clinical studies.Key words: liver hemangiomas - treatment methods.

[Rare malignant tumors of the appendix: surgical treatment of liver metastases case reports]. / Vzácné maligní nádory apendixu: lécba metastáz do jater kazuistiky.

INTRODUCTION: Tumors of appendix vermiformis are quite rare; they represent only about 0.4% of gastrointestinal tract tumors. They can be both benign and malignant (primary or secondary). Carcinoid is the most common tumor of the appendix. The symptoms can include nothing but non-specific abdominal pain, or on the contrary they can imitate inflammatory acute abdomen. Liver metastases are associated with an advanced stage of malignancy; their surgical treatment is presented rarely in the literature. The aim of this publication is to present two cases with different results of surgical treatment of liver metastases with the primary tumor located in the appendix. CASES: The first patient is a 50 years old female who underwent right hepatectomy for liver metastases of Goblet-cell carcinoid of the appendix in 2013 and died six months later due to tumor progression. The second patient is a 58 years old male, still alive, undergoing repeated liver and lung resections and RFA from 2009 due to metastases from appendix carcinoma. CONCLUSION: Examples of dissemination of malignant appendix tumors to the liver need to be evaluated individually. In indicated cases, surgical treatment of liver metastases is justifiable.Key words: tumors of appendix liver metastases surgical treatment.

[Liver metastases of malignant melanoma - utility of resection or radiofrequency ablation]. / Jaterní metastázy maligního melanomu - mají resekce nebo radiofrekvencní ablace smysl?

INTRODUCTION: Incidence of cutaneous and uveal forms of malignant melanoma (MM) has increased significantly in the population in the last years. Biological behavior of both these forms of MM is different and is associated with the development of liver metastases. The prognosis of patients with MM liver metastases is generally poor. The authors seek to consider the sense and the possibilities of surgical treatment of MM liver metastases. METHOD: Seven patients with liver metastases of MM were operated on in the Hepatobiliary Center of the Department of Surgery, University Hospital in Pilsen during the last ten years. Four patients suffered from the uveal and three from the cutaneous form of MM. Mean age of the patients was 58.8 years. R0 liver resection was performed in 3, and radiofrequency ablation in 1 patient. In the remaining 3 patients the operation finished by exploratory laparotomy due to tumor progression. RESULTS: Two patients died in the interval of 6 and 25 months after liver surgery for tumor dissemination. Two patients continue to show disease free survival, currently of 22 and 28 months. CONCLUSION: Liver metastases of MM have a very poor prognosis. Surgical treatment indicated by the multidisciplinary team provides, together with further multimodal treatment, a chance for long-term survival and its indication is justified in selected patients.Key words: malignant melanoma - liver metastases - surgical treatment.

[The Influence of Palliative Chemotherapy on the Quality of Life of Patients with Gastric Cancer]. / Vliv paliativní chemoterapie na kvalitu zivota nemocných s karcinomem zaludku.

BACKGROUND: Gastric cancer is a malignant disease with a poor prognosis. The incidence of gastric cancer in the Czech Republic in 2013 was 14.34 cases per 100,000 citizens. Unfortunately, most patients are dia-gnosed with advanced stage disease and therefore undergo palliative treatment. Some patients undergo surgery and a very small percentage undergo palliative chemotherapy. The five year survival rate for those with advanced gastric cancer ranges from 5-15%. METHODS: This is a prospective study of patients undergoing chemotherapy for advanced gastric cancer. The aim was to assess the quality of life of those undergoing chemotherapy. RESULTS: The results showed that chemotherapy reduced the quality of life for these patients. DISCUSSION: Although palliative chemotherapy prolonged time to progression, it had little impact on overall survival. Conversely, chemotherapy reduced quality of life. Thus, clinicians and patients must decide whether to begin palliative chemotherapy. The final decision should be made by the patient after discussion with the treating clinician. CONCLUSION: Treatment of patients with gastric cancer must be undertaken on an individual basis. Those undergoing palliative treatment must play an active role in the decision process regarding chemotherapy and assess the potential benefits and drawbacks. Because chemotherapy treatment has a detrimental effect on quality of life, the decision should be based on factors that predict the likely therapeutic effect of chemotherapy. A definitive decision can then be made as to whether chemotherapy is indicated.

[Predictive and prognostic factors of gastric cancer]. / Prediktivní a prognostické faktory karcinomu zaludku.

INTRODUCTION: Gastric cancer is a frequent malignant disease with poor prognosis. Most patients undergo only palliative treatment. Chemotherapy is another alternative but its effect differs in individual patients. METHOD: This is retrospective study. We enrolled 54 patients (N=54) according to the inclusion criteria. We performed quantification of gene expression of selected genes and some microRNA from tumour tissue, which was used for the diagnosis. Statistical analysis of the data was performed. RESULTS: We demonstrated a predictive value of gene expression of thynidylate synthase in tumour tissue for a therapeutic effect of chemotherapy based on 5-Fluorouracil or Capecitabine. At the same time, we demonstrated a predictive value of miR181, miR150, mir192 and miR342 microRNA levels from the tumour tissue. In addition, we succeeded to demonstrate a predictive value of miR221, miR224, miR520 and miR375 microRNA levels for a therapeutic effect of chemotherapy based on platinum derivates. CONCLUSION: Thanks to the use of efficient therapy predictors, we can distinguish those patients who will profit from chemotherapy from patients where an effect cannot be expected. Thanks to personified oncology therapy the quality of life of some patients can be improved while reducing the costs of the therapy by avoiding inefficient chemotherapy. Only an early diagnosis of gastric cancer can reverse the adverse prognosis of patients with this disease. KEY WORDS: gastric cancer - microRNA - prognostic markers - predictive markers.

[Comparison of percutaneous and open approach to radiofrequency ablation of colorectal liver metastases in Teaching Hospital Pilsen in 20012015]. / Porovnání perkutánní a otevrené radiofrekvencní ablace metastáz kolorektálního karcinomu ve FN Plzen v letech 20012015.

INTRODUCTION: Radiofrequency ablation (RFA) is a well-established method for palliative therapy of unresectable liver tumors. We use an open or percutaneous approach for the treatment of colorectal liver metastases (CLM). METHOD: Clinical data of patients undergoing percutaneous or open RFA for CLM between January 2001 and January 2015 were included in the retrospective study. We evaluated clinical factors for overall survival (OS), no evidence of disease (NED) and non-ablation in relation to tumor sizes and numbers, type of approach and type of used probes. RESULTS: 147 patients underwent RFA for CLM in this time period. Mean age was 65 years. 168 RFAs were performed in total. OS was influenced by a high number of censors. OS for the first and third years was 93.6% and 61% with no statistical differences between the percutaneous and open approach. NED was significantly shorter in patients with the percutaneous approach. NED was not influenced neither by size nor number of the lesions. A higher risk of non-ablation was observed as statistically significant in patients with percutaneous RFA. A higher, although not statistically significant, risk of non-ablation was also observed for larger metastases. Patients with percutaneous RFA showed a shorter stay in the hospital and fewer complications. CONCLUSION: RFA is an alternative approach to the treatment of unresectable CLM. In our study the open approach was associated with a lower risk of non-ablation. Percutaneous RFA showed a lower risk of complications and a shorter stay in the hospital. KEY WORDS: radiofrequency ablation percutaneous RFA colorectal liver metastases CLM palliative therapy.

[Granulomatous inflammation in differential diagnosis of hepatobiliary malignancy]. / Granulomatózní zánety v diferenciální diagnostice malignit hepatobiliárního traktu - kazuistiky.

UNLABELLED: The authors present two case reports to demonstrate wide differential diagnosis of granulomatous disorders of the hepatobiliary tract. Isolated granulomatous disorders are very rare in this area. Differantial diagnosis includes infectious and systemic diseases or chemical irritation. Granulomas often immitate malignant tumors and the surgeon could be first to diagnose this disease during liver resection or cholecystectomy. KEY WORDS: granulomatous inflammation hepatic granuloma non-specific inflammation liver resection cholecystectomy.

[Castleman disease - unusual finding after operation of retroperitoneal tumor of young patient]. / Castlemanova choroba - neobvyklý nález pri operaci tumoru retroperitonea u mladého nemocného.

UNLABELLED: Castleman disease is rare diagnosis. It was first mentioned in literature in 1954 by doctor Castleman and Lown. It is rare sickness which primary affects lymfatic nodes. There are four histo-morfologic subtypes and two clinic manifestations (uni and mulicentric). Comon clinical picture is simple lymfadenopathy of neck, medistinal a retroperitonal lymfatic nodes. Signs of this disease are heterogenic and depend on histological subtype. Also prognosis depends on type of illness. It should take place as benign diagnosis (unicentric form) but also can be potencionally malignant form which shlould exacerbate to malignant lymfoproliferation (multicentric form). Authors present the case of 29 years old men with clinical manifestation (jundice, intermitent bowel obstruction) of lagre retroperitoneal tumor in subhepatal localization. The treatment was radical surgical extirpation, surgery was without complications. Definitive histological diagnosis was confirmed as hyaline-vascular type of Castleman disease. Because the patient´s clinical form was multicentric, he is now undergoing adjuvant oncological treatment. KEY WORDS: Castleman disease reproperitoneal tumor.

Surgical treatment of gastric cancer.

UNLABELLED: Gastric cancer is a malignant disease which has generally a very bad prognosis. The frequency of occurence of this disease in the population is dependent on the age and localisation. Most frequently, this disease has occured in Japan, China, countries of South Africa and Eastern Europe for a long time but men are more likely to suffer from this disease than women witha ratio of 2 : 1. METHODS: We retrospectively evaluated the group of patients who had been treated in our complex oncology center in the course of five years RESULTS: We treated 572 patients with gastric cancer in five years period. 218 patients of the total number were admitted, 185 patients of all hospitalized patients were operated (85 %). 53 patients of our group of hospitalized patients underwent adjuvant oncology therapy (24 %). Overall, five-year survival was 18.4 % in our group, the median survival time was 12.9 months. CONCLUSION: Radical surgery is considered to be the only treatment modality which can lead to patient´s cure under optimal conditions. Complex care for patients with gastric carcinoma should be centralized in big centers. Personalized oncological treatment should be a way how to get better results (Tab. 2, Fig. 5, Ref. 14).

[Cerebral salt wasting syndrome (CSWS) - rare case from a surgical department]. / Cerebral salt wasting syndrom (CSWS) - nezvyklá kazuistika z chirurgického pracoviste

INTRODUCTION: Cerebral salt wasting syndrome (CSWS) is one of several possible causes of the development of hyponatraemia in patients with severe cranial trauma associated with intracranial bleeding and brain oedema. Other possible causes of post-traumatic hyponatraemia include the syndrome of inappropriate antidiuretic hormone secretion (SIADH). CASE HISTORY: The authors present the case of a twenty-five-year-old polytraumatized female patient who was treated in our department and who was diagnosed with cerebral salt wasting syndrome. CONCLUSION: In patients with severe cranial trauma and subsequent hyponatraemia, CSWS should be considered. It is crucial to distinguish between CSWS and SIADH as wrongly selected treatment can have serious or even fatal impacts for a gravely injured patient.

[Pulmonary metastases - 12-year experience with surgical therapy]. / Plicní metastázy - dvanáctileté zkusenosti s chirurgickou lécbou.

INTRODUCTION: Nowadays, radical surgical therapy of selected secondary pulmonary tumours is a generally accepted therapeutic procedure that has been proven to extend long-term survival of the patients with acceptable perioperative morbidity and mortality. The authors present a retrospective analysis of a set of patients who underwent surgery for pulmonary metastases of various tumours in a 12-year period. MATERIAL AND METHODS: In 2001-2012, 159 patients with secondary pulmonary tumours were operated on at the authors department, of whom 80 were men; the median age was 65 years. Solitary metastases were present in 112 patients (70.4%); the other patients had multiple metastases; 24 patients (15.1 %) suffered from bilateral involvement, and 6 patients (3.8%) suffered from relapsed metastatic disease after previous radical surgery. Colorectal carcinoma metastases were diagnosed in most cases (75 people - 47.2%). The median disease-free period from the surgery of the primary tumour was 27 months in the patient set. RESULTS: In total, 166 unilateral (87.4%) and 24 bilateral surgeries were performed using one- or two-stage procedure (12.6%). Precise laser excisions represented the most common type of surgery (59 procedures - 31.1%). In total, 296 metastases were radically resected, and 13 were treated using radiofrequency ablation. Perioperative morbidity was 13.2% with a zero lethality rate. 90 operated patients (56.6%) still survive after the metastasectomy, with median survival of 44 months. The overall 3-year survival in the set was 59%, and 5-year survival was 39%. The number of metastases is a statistically significant factor affecting survival in the patient cohort with colorectal carcinoma metastases, the risk of death being 2.7 times higher in patients with 2 and more colorectal carcinoma metastases. 68 patients (42.8%) live without progression of the disease after the metastasectomy, with the median disease-free interval of 29 months. In total, 43% of the patients were free of any signs of relapse or disease progression for 3 years, and 27% for 5 years. The risk of disease progression is 2.1 times higher in patients with 2 and more metastases of any tumour, and for colorectal carcinoma this risk is 2.3 times higher. CONCLUSION: The achieved results confirm the positive role of pulmonary metastasectomy in disseminated tumour therapy. The number of metastases is the decisive prognostic factor affecting both long-term survival of operated patients and their DFI.

Feasibility of cerebral blood flow and oxygenation monitoring by continuous transcranial Doppler combined with cerebral oximetry in a patient with refractory cardiac arrest treated by extracorporeal life support.

The adequacy of cerebral blood flow and the level of regional oxygen saturation during CPR and early post-resuscitation phases assuring favorable neurological outcome are not known. We demonstrate the feasibility of cerebral blood flow and oxygenation monitoring by a continuous transcranial Doppler combined with cerebral oximetry in a patient with refractory cardiac arrest treated by extracorporeal life support.

[Liver and pulmonary metastases of the colorectal carcinoma - the experience of the Department of Surgery, University Hospital in Pilsen]. / Jaterní a plicní metastázy kolorektálního karcinomu - zkusenosti Chirurgické kliniky FN v Plzni.

INTRODUCTION: Liver and pulmonary metastases of the colorectal carcinoma develop in about 20-70%, resp. in 10-22% patients with the colorectal carcinoma. Their treatment is still a matter of discussion. The aim of our study was to evaluate the results of surgical treatment as a part of the multimodal approach. MATERIAL AND METHODS: 30 patients with liver and pulmonary colorectal metastases were operated on between 2002 and 4/2013. The average age was 62.8 ± 10.7 years. 19 patients had metachronous and 11 synchronous metastases. The liver metastases preceded pulmonary in 14 cases, and vice versa in 5 patients. Both types of metastases developed in seven patients simultaneously. Liver resection was performed in 23, radiofrequency ablation (RFA) in 7 patients. Laser pulmonary metastasectomy was performed in 15, pulmonary resection in 14 and RFA in one patient. The liver procedure preceded pulmonary in 25 patients. 73.3% patients had adjuvant oncological treatment. RESULTS: 30 days mortality rate was 3.3% (N=1) for the actinomycotic sepsis complicated with MRSA infection. Morbidity rate was 10%. Recurrence of liver metastases developed in 6 patients. RFA was performed in all patients. The median of overall and disease free survival was 6.9, resp. 1.1 years. CONCLUSION: Surgical treatment as a part of the multimodal treatment is the only radical treatment for patients with liver and pulmonary metastases. It offers good long-term results.

[Double gallbladder - a rare congenital variation]. / Duplikatura zlucníku - vzácný nález.

Double gallbladder, a congenital anatomic variation, represents approximately 2% of all congenital anatomic variations of the gastrointestinal tract, its incidence amounting to about 25 in 100 000. It has several types classified according to Boyden's criteria. The diagnostic method of first choice is ultrasonography. When the patient has no health complaints and cholecystolithiasis is present, no special treatment measures are required. The treatment option in symptomatic cholecystolithiasis is laparoscopic cholecystectomy. Only a few cases of double or triple gallbladder, in contrast to the high number of cholecystectomies, have been published in literature. The authors present a case of double gallbladder where the diagnosis was established more than three years after laparoscopic cholecystectomy
