Abstract
INTRODUCTION Minimally-invasive surgical methods have been becoming ever more common also in the segment of pancreatic surgery. The aim of this paper was to analyze the current state of minimally-invasive surgery in the Czech Republic and the justification and potential of implementing such procedures. METHODS Analysis of high volume centers using healthcare providers´ and payers´ data. RESULTS Thirteen pancreatic surgical centers meet the proposed criteria for being called a high volume center - a center of highly specialized care in pancreatic surgery based on the annual number of at least 17 major resections of the pancreas. According to data from healthcare payers, laparoscopy was used in 0.6%-65.7% of procedures in individual centers. However, these are not resection procedures. The centers themselves report a significantly smaller number of minimally-invasive pancreatic resection procedures. The actual numbers of minimally-invasive resection procedures in the current system are practically impossible to verify. The potential for implementing minimally-invasive pancreatic surgery in the Czech Republic can be estimated based on the identification of candidate patients. CONCLUSION Due to the fragmentation of this operative segment, its costs and small numbers of patients suitable for minimally-invasive pancreatic surgery even among high volume centers, the implementation rate of these methods is very slow. The need to centralize this segment of care appears to be very urgent from all points of view.

Abstract
Hemobilia is a rare condition defined as bleeding in the biliary tract. The clinical presentation is variable. The typical manifestation consists of jaundice, upper gastrointestinal bleeding, and right upper quadrant abdominal pain. This set of symptoms is known as "Quincke's triad." It is present in only 22%-35% of cases. Post-traumatic hemobilia is an extraordinarily rare condition occurring in only 6% of the patients with hemobilia. In general, it occurs in less than 0.2% of patients with liver trauma. A delay in the development of bleeding after liver trauma is frequent. Early diagnosis is essential because massive bleeding into the biliary tract is a potentially life-threatening condition. We present a case of a patient with massive hemobilia developed 12 days after blunt abdominal trauma. Computed tomography angiography showed two pseudoaneurysms in hepatic segments V and VIII with contrast medium extravasation. We successfully performed digital subtraction angiography with selective transcatheter arterial embolization of the leaking segment VIII pseudoaneurysm. Embolization of the pseudoaneurysm in segment V was technically impracticable. Our article provides a review of the published literature focussing on the prevalence, diagnostics, and treatment of post-traumatic hemobilia.

Abstract
OBJECTIVES The vascular supply to the neck and body of the pancreas is highly variable. The dorsal pancreatic artery is the dominant artery feeding this area. The aim of this study was to describe the vascular supply of postresection pancreatic remnants after pancreaticoduodenectomy. Patients with hazardous anatomical arrangement may be at a higher risk of postresection remnant ischemia and postoperative pancreatic fistula development. METHODS The modified Whipple procedure was performed on 20 cadaveric donors. The macroscopic anatomical supply of the postresection pancreatic remnant of each donor was evaluated. RESULTS The arterial supply of the postresection remnant was highly variable. In 30% of cases (6/20), the dorsal pancreatic artery was cut during the pancreatoduodenectomy or it was missing. In these cases, the area of the pancreaticojejunostomy construction was fed only through anastomoses between the transverse pancreatic artery and the pancreatic branches of the splenic artery. CONCLUSIONS In 30% of cases, the arterial supply of the postresection pancreatic remnant was dependent on inconstant intraparenchymal arterial anastomoses. These patients may be at a higher risk of postoperative pancreatic fistula development.

Abstract
The role of radiotherapy in borderline resectable (BRPC) and locally advanced pancreatic carcinoma (LAPC) remains controversial. In our study, we retrospectively evaluated 48 patients with BRPC (14; 29.2%) and LAPC (34; 70. 8%) who underwent 6-8 cycles of induction mFOLFIRINOX chemotherapy alone (23; 47.9%) or 4-6 cycles of mFOLFIRINOX followed by hypofractionated radiotherapy (up to the total dose of 39.9 Gy in 15 fractions) (25; 52.1%). Survival parameters were evaluated using the Gehan-Breslow-Wilcoxon Test and compared by using the long-rank test. The addition of radiotherapy was not associated with better survival (16.9 months for chemotherapy only versus 15.9 months for the combined therapy; p=0.486), as well as for both subgroups (13.5 months vs. 18.3 months; p=0.679) and (20.7 months vs. 13.8 months; p=0.425) for BRPC and LAPC, respectively. A higher resection rate was seen in the BRPC group compared to the LAPC group (43% vs. 17.6%, respectively). Our study revealed a significantly higher rate of lung metastases in patients after the combination therapy compared to those treated by chemotherapy only (19% vs. 0%, respectively; p=0.045). Such a borderline result, however, prevents us from drawing clear conclusions about whether this is an artifact caused by the low number of patients or whether radiotherapy leads to a selection of stem cells with a predilection to the generalization to the lungs.

Abstract
BackgroundPostoperative pancreatic fistula is one of the most dreaded complications following pancreatic resections with Grade C the most severe. Several possible types of surgical intervention are available but to date, none of them have clearly shown superiority. This study aims to compare different surgical approaches.MethodsA retrospective analysis of patients who underwent revision surgery for postoperative pancreatic fistula between 2008 and 2020 was performed. Three surgical approaches were compared: open drainage; a disconnection of the pancreaticojejunostomy; and salvage total pancreatectomy. The data of nine monitored parameters were collected. Selected parameters were statistically analyzed and compared.ResultsA total of 54 patients were included. Eighteen patients underwent open drainage, 28 had disconnections of the pancreaticojejunostomy and eight had salvage total pancreatectomy. Statistically significant differences were observed in the time of Intensive Care Unit stay, the number of surgical interventions, 90-day mortality, the number of administered blood transfers and treatment costs. Open drainage showed to be superior in each category. The difference in long-term survival also slightly favored simple drainage.ConclusionOpen drainage procedure showed to be superior to other types of interventions in most of the monitored parameters. Disconnection of the pancreaticojejunostomy and a salvage total pancreatectomy had similar results, which correlated with the surgical burden of these interventions.

Abstract
BACKGROUND/OBJECTIVES The dorsal pancreatic artery is the main artery of the body and tail of the pancreas. Its origin and branching is highly variable. The aim of this study was to perform a meta-analysis to generate pooled prevalence data on the presence and origin of the dorsal pancreatic artery. Clinically important aspects of the dorsal pancreatic artery were summarised during the literature review. METHODS Major medical databases were searched. Data on the presence and point of origin of the dorsal pancreatic artery were extracted and quantitatively synthesised. The obtained data of anatomical based studies and computed tomography based studies were statistically analysed. RESULTS In total, 30 studies, comprising 2322 anatomical and computed tomography based cases were included. The dorsal pancreatic artery was present in 95.8% of cases. It originated from the splenic artery in 37.6% of cases, common hepatic artery in 18.3% of cases, coeliac trunk in 11.9% of cases and the superior mesenteric artery in 23.9% of cases. Other rare origins were present in 2.77% of cases. Multiple dorsal pancreatic arteries were found in 1,7% of cases. There was no significant difference in the presence or origin of the dorsal pancreatic artery between anatomical and computed tomography based studies. CONCLUSION The dorsal pancreatic artery is present in the vast majority of cases. Its origin and branching are highly variable. Multiplicity of the dorsal pancreatic artery is infrequent.

Abstract
The trend of minimally invasive surgery expands even into the most technically demanding areas, including HPB surgery. Faster recovery and elimination of surgical site infections achieved with a minimally invasive approach provides, in addition to a better quality of life, the possibility of starting adjuvant treatment earlier. However, evidence of non-inferiority of short-term and oncological results compared to open surgery is required. In minimally invasive distal pancreatectomy, there is sufficient evidence to suggest that it as the method of choice for benign tumors and low-grade malignancies. For pancreatic cancer, the long-term results so far appear to be equivalent, although this still needs to be confirmed by ongoing randomized controlled trials (RCT). Enucleation of accessible lesions is also a suitable procedure for the minimally invasive approach. In contrast, in pancreaticoduodenectomy, available evidence does not demonstrate a clear benefit of the minimally invasive approach. Safety concerns still remain, and not even formal training has been successful in eliminating the consequences of the long learning curve for perioperative outcomes. Robotic approach appears to be more promising than laparoscopy for pancreaticoduodenectomy. Key words: pancreaticoduodenectomy distal pancreatectomy minimally invasive - laparoscopic robotic.

Abstract
INTRODUCTION Ischemic complications are a notable cause of morbidity in patients after pancreatic head resections. Stenosis of celiac axis in patients undergoing pancreatoduodenectomy requires further perioperative attention. CASE REPORT We present a patient with pancreatic head malignancy scheduled for Whipple procedure in the setting of hemodynamically significant celiac axis stenosis. Despite release of the artery from compression by median arcuate ligament, elevation of liver function tests on the first postoperative day was noted. Endovascular stenting was performed on the same day with significant radiological improvement and subsequent normalization of laboratory values. The patient had no further postoperative complications. CONCLUSION Fast recognition of ischemic complications after pancreatic head resection is crucial. Even postoperatively, endovascular intervention might be a feasible treatment modality of celiac axis stenosis in selected patients who undergo pancreatoduodenectomy.

Abstract
Multiple Endocrine Neoplasia (MEN) is a condition in which several endocrine organs of an individual are affected by adenoma, hyperplasia and less often carcinoma, either simultaneously or at different stages of life. Two existing syndromes, MEN1 and MEN2 (2A, 2B), in literature is also mentioned MEN4, are associated also with other non-endocrine disorders. MEN1 (Wermer syndrome) affects the pituitary, parathyroid, and pancreatic area. 95 % of patients show very early manifestation of hyperparathyroidism, often before 40 years of age. Multiple adenomas gradually involve all four parathyroid glands. The first clinical sign of MEN1 includes recurrent nephrolithiasis. The second most frequent manifestation of MEN1 is pancreatic area (pancreas, stomach and duodenum), again multiple malignancies of varying degree which can metastasize. Most often gastrinomas and insulinomas are involved. Pituitary adenomas occur in about one third of MEN1 patients and tend to be larger and less responsive to treatment. Tumors appearing most often are prolactinomas, tumors producing growth hormone, or afunctional adenomas. The other endocrine tumors include carcinoids and adrenal lesions. In the last year we have registered four MEN1 syndrome patients in our center and one patient has been already followed since 2008. In four out of five patients, nephrolithiasis after 30 years of age was the first clinical symptom, but only one of theses cases resulted in MEN1 diagnosis. In all patients, the clinical symptoms intensified and the diagnosis was established between 36 and 40 years of age. A crutial factor is a cooperation with the urology examination of kidney stones formation in young individuals with nephrolithiasis in order to reveal the potential cases of MEN1 syndrome very early on. Consider the MEN1 genetic diagnostics if recurrent primary hyperparathyroidism or recurrent gastroduodenal ulcer disease appear in patients under 40 years of age.Key words: carcinoid - gastrinoma - hyperparathyroidism - insulinoma - MEN1 - multiple endocrine neoplasia - nefrolithiasis - neuroendocrine tumor - pancreatic area - pituitary gland.

Abstract
INTRODUCTION Irreversible electroporation (IRE) is a quite novel method of tissue ablation. Its mechanism of action that does not use thermal energy is the most important feature of the method. Current experience with IRE in animal studies and in clinical practice are summarized in the paper. In particular, the paper is focused on using IRE in locally advanced pancreatic carcinoma. METHOD The basic principle of IRE is that it causes micropores in the phospholipid membrane of cells. This leads to an impairment of cellular homeostasis and programmed cell death - apoptosis. Because of absence of protein denaturation this method spares tubular structures like vessels and ducts. This is the key feature that allows to use IRE in the pancreas where common thermic ablative procedures cannot be used for difficult anatomic circumstances and resulting injury of surrounding structures. PRE-CLINICAL AND CLINICAL STUDIES: The ability to spare vascular structures and ducts was confirmed in many animal studies. Subsequently, IRE was safely utilized also in human liver, pancreas, lung and kidneys. IRE in the treatment of advanced pancreatic cancer: Most experience with IRE ablation has been gathered for locally advanced pancreatic carcinoma where clinical studies published in the recent 5 years have provided encouraging results. CONCLUSION Irreversible electroporation is a safe method used to decrease tumour mass in pancreatic cancer. Further studies are needed to determine its therapeutic efficiency.

Abstract
INTRODUCTION Cystic lesions of the pancreas (CLP) are of different origin and behaviour. Mucinous lesions with the risk of invasive cancer represent an important subgroup. The key point in differential diagnosis of CLP is to distinguish malignant and benign lesions and also correct indication for surgery in order to minimize the impact of serious complications after resection. Different and unsatisfying predictive values of each of the examinations make proper diagnosis challenging. We focused on overall diagnostic accuracy of preoperative imaging and analytic studies. We studied the accuracy of distinguishing between non-neoplastic vs. neoplastic and bening vs. malignant lesions. MATERIAL AND METHODS We retrospectively analyzed all of the patients (N=72) with CLP (median of age 58 years, range 22-79) recommended for surgery. CT, EUS, ERCP, MRCP findings, cytology and aspirate analysis were used to establish preoperative diagnosis. Finally, preoperative diagnoses were compared with postoperative pathological findings to establish overall accuracy of preoperative assessment. RESULTS During 5 years, 72 patients underwent resection for CLP. We performed 66 (92%) resection and 6 (8%) palliative procedures with 32% morbidity and 7% of one hospital stay mortality. All the patients were examined by CT and EUS. FNA was performed in 44 (61%) patients. Cytology was evaluable in 39 (88%) cases. ERCP was done in 40 (55%) patients. Pathology revealed non-neoplastic CLP in 25 (35%) and neoplastic lesions in 47 (65%) specimens. Mucinous lesions accounted for 25%. Malignant or potentially malignant CLP were found in 37 (51%) patients. Sensitivity, specificity and diagnostic accuracy of preoperative diagnosis for distinguishing between inflammatory and neoplastic, and benign and malignant was 100%, 46%, 85% and 61%, 61%, 44%, respectively. CONCLUSION Correct and accurate preoperative assessment of CLP remains challenging. Despite the wide range of diagnostic modalities, the definitive preoperative identification of malignant or high-risk CLP is inaccurate. Because of this, a significant portion of the patients undergo pancreatic resection for benign or inflammatory lesions that are not potentially life-threatening. Possible serious complications after pancreatic surgery are the main reason for precise selection of patients with cystic affections recommended for surgery.

Abstract
INTRODUCTION Intrahepatic lithiasis (IHL) has a low incidence rate in countries with high social-economical level, with mostly secondary ethiology. The commonest signs include: cholangoitis, obstruction icterus, liver absces and secondary biliary cirrhosis. Although a wide range of treatment methods is available, in some cases, surgical management is the only alternative. METHODS The authors present two case reviews of IHL patients. The first case includes a 56-year old male, unsuccessfuly operated in another clinic. The patient was referred to the author's clinic for a relaps of septic complications. He underwent extensive revision of his bile ducts up to the segmental bile duct level with a mechanical removal of concrements, introduction of the T-drain and postoperative cholangiography for secondary IHL of the left hepatic duct. A resection procedure was not indicated due to absence of the liver parenchyma impairment. The other patient, a 77-year old male, underwent left lateral bisegmentectomy for a primary IHL of the SII and SIII liver segments with signs of irreversible bile duct impairment, which could not be managed endoscopically. RESULTS No complications during the first patient's postoperative course were recorded. A postoperative Day 7 cholangiographic examination detected free intrahepatic bile ducts. The patient has not shown any signs of a IHL relaps. The second patient's postoperative course was complicated by biliary secretion from the drain, which was managed endoscopically. A histological examination confirmed the preoperative diagnosis. CONCLUSION IHL which cannot be managed by endoscopy or other procedures, is indicated for surgery. The type of the surgical procedure depends on the extent of the intrahepatic bile duct and liver parenchyma impairment.
