[Pancreatic cancer with liver metastases: is it possible to improve survival by resection of oligopersistent primary tumor following neoadjuvant chemotherapy?] / Májáttétes pancreasrák: meghosszabbítható-e a túlélés az oligoperzisztens primer daganat neoadjuváns kemoterápiát követo reszekciójával?

The prognosis of pancreatic cancer is one of the worst of all cancers. Though the routine use of modern targeted and immunotherapy is still pending, the recently applied new chemotherapy combinations resulted in obvious improvement in the clinical management of pancreatic cancer. Adjuvant treatment followed by radical operation can increase the survival of the patients, moreover, neoadjuvant therapy for locally advanced tumors is associated with higher resectability rate. However, in metastatic disease only palliative chemotherapy could be indicated due to the dismal prognosis. The introduction of new chemotherapy combinations produced a major evolution by extending the median survival time of these patients. According to recent publications, even complete remission of the metastases can be achieved by the palliative chemotherapy, justifying a radical operation. This approach can be more advantageous, compared to patients treated with chemotherapy only. Reporting our two primary metastatic cases, we also endorse this new approach. The clinical significance of complex management is justified in the case of oligopersistence which is traditionally treated only with palliative systemic therapy.

Novel Noninvasive Paraclinical Study Method for Investigation of Liver Diseases.

Based on a prior university patent, the authors developed a novel type of bioimpedance-based test method to noninvasively detect nonalcoholic fatty liver disease (NAFLD). The development of a new potential NAFLD diagnostic procedure may help to understand the underlying mechanisms between NAFLD and severe liver diseases with a painless and easy-to-use paraclinical examination method, including the additional function to detect even the earlier stages of liver disease. The aim of this study is to present new results and the experiences gathered in relation to NAFLD progress during animal model and human clinical trials.

Krónikus pancreatitis miatt végzett pancreasfej-resectiós mutéteink elemzése.

Introduction: In case of chronic pancreatitis with inflammatory enlargement of the pancreatic head, several operations exist for the treatment, such as the Beger-, Frey-, Whipple-procedures and the Berne modification. A comparison of the results of these procedures is presented in this study. In addition to this, innovations in pancreatojejunal and biliodigestive anastomosis are also described. Material and Methods: 231 pancreatic head resections were carried out between 1991 and 2021. The data were retrospectively evaluated. Late results were also examined using questionnaires. Results: The Berne modification and the Frey-procedure were more advantageous, than the Whipple- and the Beger-operation in terms of operating time, need for transfusion (P < 0,001), while regarding, the postoperative intensive care unit and total hospital stay both procedures were more favourable, than the Whipple one (P < 0,001). The early morbidity rate was the highest after the Whipple-procedure (P = 0,004). These differences were statistically significant. The reoperation and mortality rates were comparable between the groups. The quality of life of the patients was acceptable, nevertheless in the majority of the cases the alcohol and nicotine abuse was not stopped. Conclusion: The Frey-operation and the Berne modification were the most advantageous, regarding the early postoperative outcomes. However the latter one is preferable, due to its simplicity. During these procedures a single layer continuous suture technique was used for the pancreatojejunal anastomosis, and an extrapancreatic biliodigestive anastomosis is recommended for the solution of cholestasis. due to the superior results.

Changes in Oncological Surgical Principles Driven by Advances in Preoperative Treatments.

From a surgical point of view, the development of preoperative oncological treatment has had a profound effect on the surgical treatment trends of cancer as well as on the outcomes of cancer patients. Consequently, these changes have challenged formerly entrenched oncological surgical principles. In our short report, we aimed to summarize the main shifts regarding the surgical principles of cancer treatment due to the development of preoperative oncological therapy in recent years. As a result of successful preoperative treatment, surgeons may perform less radical surgeries, the required free resection margin has been narrowed down to a few millimeters in dimension and preoperative treatment is justified in both definitely resectable tumors and in oligometastatic tumors as well. For prognosis assessment, the post-preoperative oncological treatment stage is now considered decisive, rather than the pretreatment stage as previously thought. Other changes include the introduction of the watch and wait strategy and the reverse order of treatment of the primary tumor and metastasis. Observing the continuously improving outcomes of cancer patients and the developments in oncological treatment modalities, a further expansion of the indication of preoperative treatments is to be expected.

[Robotic-assisted laparoscopic Heller-Dor's cardiomyotomy and fundoplication for achalasia]. / Achalasia miatt végzett robotasszisztált laparoszkópos cardiomyotomia és fundoplicatio (Heller­Dor-mutét).

INTRODUCTION: The outcomes of surgical interventions for achalasia treatment improved with the advent of minimally invasive surgery. Robotic-assisted Heller-Dor's (RAHD) procedure established over the last years, provides important advantages to surgeons, such as binocular three-dimensional vision and improvement of fine motor control. METHOD: Between October and December of 2022, first in Hungary, 3 patients (37-year-old man, 55- and 72-year-old women) underwent RAHD procedure for achalasia at the Clinical Centre of the University of Pécs using the da Vinci Xi system. RESULTS: RAHD procedure was feasible without any particular problems and the postoperative course of all three patients was uneventful. The operation times were 198, 204 and 238 minutes, including 23, 19 and 14 minutes for the setup time of the robot. By the last patient, due to an accompanying hiatal hernia, an additional hiatal reconstruction was also performed. In the first 2 cases, the patients were discharged on the 4th postoperative day, while in the last case, with the additional hiatal reconstruction, the patient was emitted on the 6th postoperative day. DISCUSSION: There are several published studies about RAHD cardiomyotomy. The general conclusion is that, in experienced hands, RAHD procedure is easy to perform, ensures a meticulous esophageal and gastric myotomy, allowing to visualize and divide each muscle fiber with a significantly lower rate of mucosal perforations. However, by RAHD procedure, the overall costs are higher, including a longer operation time during the learning curve. At the same time, the avoidance of mucosal lacerations and their possible consequences has to be weighed against the higher overall costs. CONCLUSION: Laparoscopic cardiomyotomy is the first standard upper-gastrointestinal operation where a clear advantage of the use of a surgical robot has been proven. Thus, wherever this equipment is available, it should be preferred for this procedure. Orv Hetil. 2023; 164(14): 542-547.

Use of blood products during the first months of COVID-19 pandemic period: A single center report.

The novel coronavirus (SARS-CoV-2) outbreak exerted a serious effect on healthcare. Between 1st of January and May 31, 2020 due to the special regulations in Hungary, the number of reported COVID-19 infections were relatively low (3876 cases). The inpatient and outpatient care and the blood supply were significantly affected by the implemented regulations. The aim of this study was to evaluate the use of blood products amid the first five months of the pandemic situation. This investigation has observed a significant reduction of hospitalizations (37.35%). Analyzing individually the included units, pre-transfusion hemoglobin concentrations of transfused patients presented slight modifications, which were not statistically significant. The special regulations resulted major changes in the frequency of diagnoses at admissions in case of the Department of Surgery, while in case of the other specialities (Division of Hematology and Department of Anesthesiology and Intensive Therapy), there were no major changes compared to pre-pandemic period. Considering each department separately, transfused red blood cell concentrates (RBC) per patient, and the proportion of transfused patients did not change significantly. However, the combination of these modifications resulted in the significant decrease in RBC transfusions (p < 0.0001) compared to the pre-pandemic baseline. With regard to platelet and fresh frozen plasma (FFP), their usage was significantly reduced (44.40% platelet concentrates and 34.27% FFP). Our results indicate that the pandemic had an important effect on the blood product usage at the included departments by introducing different patient care policies and the temporary deferral of the elective surgical interventions. Despite the challenging circumstances of blood collection and blood product supply, the hospitalized patients received adequate care.

[Complications of esophageal reconstruction]. / A nyelocsopótlás szövodményei.

Esophageal cancer is the most common cause of esophageal resections. Esophageal replacement is still a significant challenge for surgeons, because complications can be expected in over 50% and death also occurs between 4-7%. Complications can be divided into early and late categories and into general and specific complications. From a surgical point of view, early and late specific complications are the most important aspects. Between 1993 and 2012, 540 esophageal resections were performed due to malignant tumors at the Department of Surgery, Medical Center of the University of Pécs. Stomach was used for replacement in 445 cases, colon in 38 cases, and jejunum in 57 cases. The anastomosis with stomach replacement was located to the neck in 275 cases and to the thorax in 170 cases. The colon was pulled up to the neck in each case. There were 29 cases of free jejunal replacements located to the neck, and 28 cases with a Roux-loop reconstruction located to the thorax. In the case of gastric replacement, anastomotic insufficiency developed in 55 cases, graft necrosis occurred in 8 cases, and early anastomosis stricture developed in 30 cases. These numbers are 3 conduit necrosis and 2 strictures in cases of colonic replacements. There was one anastomosis failure in the case of a thoracic jejunum replacement. Also one conduit necrosis was observed in the free jejunal neck transplantation group. Among late special complications, dysphagia is the most important, the causes of which were found in the order of frequency: anastomotic stricture, conduit obstruction, peptic and ischemic stricture, foreign body, local recurrence, functional causes, new malignant tumor in the esophageal remnant after resection and malignant tumor emerging in the replaced organ. Causes may overlap each other, and their treatment may be conservative, endoscopic or surgical. Surgical treatment is usually the last option to restore the ability to swallow and can present a significant challenge even to experienced centers. Orv Hetil. 2023; 164(7): 243-252.

Dysphagia After Esophageal Replacement and Its Treatment.

Dysphagia occurs temporarily or permanently following esophageal replacement in at least half of the cases. Swallowing disorder, in addition to severe decline in the quality of life, can lead to a deterioration of the general condition, which may lead to death if left untreated. For this reason, their early detection and treatment are a matter of importance. Between 1993 and 2012, 540 esophageal resections were performed due to malignant tumors at the Department of Surgery, Medical Center of the University of Pécs. Stomach was used for replacement in 445 cases, colon in 38 cases, and jejunum in 57 cases. The anastomosis with a stomach replacement was located to the neck in 275 cases and to the thorax in 170 cases. The colon was pulled up to the neck in each case. There were 29 cases of free jejunal replacements located to the neck and 28 cases with a Roux loop reconstruction located to the thorax. Based on the literature data and own experience, the following were found to be the causes of dysphagia in the order of frequency: anastomotic stenosis, conduit obstruction, peptic and ischemic stricture, foreign body, local recurrence, functional causes, new malignant tumor in the esophageal remnant, and malignant tumor in the organ used for replacement. Causes may overlap each other, and their treatment may be conservative or surgical. The causes of many dysphagic complications might be prevented by improving the anastomosis technique, by better preservation the blood supply of the substitute organ, by consistently applying a functional approach, and by regular follow-up.

Endoluminal Suture-technique for the Stomach Closure of an Experimental Model.

BACKGROUND/AIM: In the modern minimally invasive era, diagnostic and therapeutic endoscopic interventions are one of the most emerging fields. For the new operational techniques, it is a major aim to develop reliable instruments, such as suturing devices for flexible endoscopes. The aim of this study was to assess the feasibility of a safe and reproducible suturing technique with an endoluminal suturing device. MATERIALS AND METHODS: The evaluation of the technique was performed in twenty explanted special prepared porcine stomachs. Three different techniques were compared, single stitches, figure-of-eight, or Z-pattern and running sutures in terms of suturing time and bursting pressure. After verification of the reliability of the method, a 3 cm long full thickness incision on the stomach was closed with the endoscopic suturing device in four surviving animals. RESULTS: In our ex vivo studies, we have shown that the figure of 8 or Z- technique is the most optimal for stomach closure without considerable time-cost, thus this technique was chosen as the standard method for the in vivo study. The endoscopic stomach wall suturing was successful in all four cases, the postoperative period was uneventful and ended on the tenth postoperative day with autopsy. CONCLUSION: With the applied suturing device, the endoscopic suturing of the stomach is safe and reproducible, thus a human application may also be justified.

The Effect of Trimetazidine on Diathermy-related Thermic Injury of the Rat Liver.

BACKGROUND/AIM: Owing to new oncotherapy modalities, the importance of an R0 resection decreased in the last decade; however, liver metastasis of colorectal cancer significantly decreases survival. Furthermore, to prevent cardiovascular disease, more and more patients are treated with anti-ischemic drugs, which may influence oncologic treatments in such patients. This study aimed to examine the effect of Trimetazidine on liver surface injury after spray diathermy. MATERIALS AND METHODS: We performed standard liver resections with resection-margin spray coagulation in 36 rats on both liver lobes. In all procedures, a Pringle maneuver was performed on the right lobe, while on the left lobe, no vessel occlusion was applied. Half of the animals were on Trimetazidine therapy. In 12 animals, histologic samples were taken immediately after operation, while 12 animals were terminated 1 week later, and the remaining 12 animals 3 weeks later. After standard HE staining, histologic analysis was performed. RESULTS: When diathermy was used, a coagulation zone appeared. Destruction was slightly wider in case of Trimetazidine therapy (745.75 vs. 680.04 µm). In cases of 1-week-surviving animals, a necrotic zone was observed under the coagulated tissue, and a fibrotic zone appeared after 3 weeks. In TMZ medicated animals, the destruction zone was significantly thinner (645.08 vs. 893.76 µm; p<0.001) and the necrosis zone showed the same difference (2,430.05 vs. 3,238.45 µm; p<0.001). CONCLUSION: Administration of Trimetazidine can reduce the extent of thermic necrosis. Furthermore, a great effort should be applied to achieve R0 resection in patients on anti-ischemic therapy.

The development of one-day surgical care in Hungary between 2010 and 2019.

BACKGROUND: The constant increase in the utilization of one-day surgical care could be identified since more than a decade in most of European countries. Initially, according to the international rankings, the exploitation of one-day surgery in Hungary was not really significant. In 2010, the Hungarian policy makers intended to increase one-day surgical care as a priority strategy. The aim of our study was to analyze the evolution of the Hungarian one-day surgical care during the last decade in DRG- based performance financing system in Hungary. METHODS: The dataset of the research was provided by the National Health Insurance Fund Administration of Hungary. The most important indicators related to the one-day surgical care were compared to inpatient care (market share, number of cases, and DRG cost-weights). To discover the impact of one-day surgical care to the utilization of inpatient treatment, the number of hospitalized days was also analyzed. RESULTS: Between 2010 and 2019, the market share of one-day surgical cases increased from 42, to 80%. Simultaneously the constant increase of one-day surgical cases, the number of hospitalized days were decreased in inpatient care by 17%. The value of Case Mix Index has also increased, approximately by 140%, which could confirm that more complex interventions are being conducted in one-day surgical care as well. CONCLUSIONS: Due to the comprehensive health policy strategy related to the dissemination of one-day surgical care in Hungary, several important performance indicators were improved between 2010 and 2019. Given that Hungary belongs to the low- and middle-income countries, the results of the study could be considerable even in an international comparison.

Changes in surgical principles as a result of modern, effective, perioperative treatments / A sebészeti elvek változása a modern, hatékony, perioperatív onkológiai kezelések következményeként

Oncology has evolved to a great extent over the last quarter of century. The significant success is multifactorial, including primary and secondary prevention, the development of diagnostics, new methods of chemo-and radiotherapy, and the integration of basic research results into practice. From the point of view of surgery, the establishing and widespread practical application of the principles of preoperative oncotherapy played a major role in this development. Between 1997 and 2005, 44 patients with gastric cancer and 102 patients with borderline resectable or irresectable esophageal cancer received perioperative treatment at the Department of Surgery of the University of Pecs. The response rate was above 50% in both groups and complete pathological remission was achieved in 3 patients with gastric cancer and 17 patients with esophageal cancer. Based on our own experience and literature data, the development of seven new principles in surgical oncology were observed as the result of a very successful preoperative oncologic treatment. The desired free resection margin was reduced to the millimeter dimension in many cancer cases. Thus so-called organ-preserving procedures were made possible. Regarding the prognosis, the stage after the treatment became determinant. Complete histopathological remission could also be achievable in patients with oligometastases. In the case of a complete remission, the watch and wait tactics emerged as an option. Along the preoperative treatment of resectable colorectal liver metastases, there is no need to strive for complete remission. The treatment order of the primary tumor and its metastases can be reversed. Based on the improving results of oncology treatments, a reduction in surgical activity in the treatment of cancer patients is expected.

Effect of triclosan-coated sutures for abdominal wound closure on the incidence of abdominal wound dehiscence: a protocol for an individual participant data meta-analysis.

INTRODUCTION: Acute abdominal wound dehiscence (AWD) or burst abdomen is a severe complication after abdominal surgery with an incidence up to 3.8%. Surgical site infection (SSI) is the biggest risk factor for the development of AWD. It is strongly suggested that the use of triclosan-coated sutures (TCS) for wound closure reduces the risk of SSI. We hypothesise that the use of TCS for abdominal wound closure may reduce the risk of AWD. Current randomised controlled trials (RCTs) lack power to investigate this. Therefore, the purpose of this individual participant data meta-analysis is to evaluate the effect of TCS for abdominal wound closure on the incidence of AWD. METHODS AND ANALYSIS: We will conduct a systematic review of Medline, Embase and Cochrane Central Register of Controlled Trials for RCTs investigating the effect of TCS compared with non-coated sutures for abdominal wound closure in adult participants scheduled for open abdominal surgery. Two independent reviewers will assess eligible studies for inclusion and methodological quality. Authors of eligible studies will be invited to collaborate and share individual participant data. The primary outcome will be AWD within 30 days after surgery requiring reoperation. Secondary outcomes include SSI, all-cause reoperations, length of hospital stay and all-cause mortality within 30 days after surgery. Data will be analysed with a one-step approach, followed by a two-step approach. In the one-step approach, treatment effects will be estimated as a risk ratio with corresponding 95% CI in a generalised linear mixed model framework with a log link and binomial distribution assumption. The quality of evidence will be judged using the Grading of Recommendations Assessment Development and Evaluation approach. ETHICS AND DISSEMINATION: The medical ethics committee of the Amsterdam UMC, location AMC in the Netherlands waived the necessity for a formal approval of this study, as this research does not fall under the Medical Research involving Human Subjects Act. Collaborating investigators will deidentify data before sharing. The results will be submitted to a peer-reviewed journal. PROSPERO REGISTRATION NUMBER: CRD42019121173.

The characteristics and prognostic role of acute abdominal on-admission pain in acute pancreatitis: A prospective cohort analysis of 1432 cases.

INTRODUCTION: Pain is the most common symptom in acute pancreatitis (AP) and is among the diagnostic criteria. Therefore, we aimed to characterize acute abdominal pain in AP. METHODS: The Hungarian Pancreatic Study Group prospectively collected multicentre clinical data on 1435 adult AP patients between 2012 and 2017. Pain was characterized by its intensity (mild or intense), duration prior to admission (hours), localization (nine regions of the abdomen) and type (sharp, dull or cramping). RESULTS: 97.3% of patients (n = 1394) had pain on admission. Of the initial population with acute abdominal pain, 727 patients answered questions about pain intensity, 1148 about pain type, 1134 about pain localization and 1202 about pain duration. Pain was mostly intense (70%, n = 511/727), characterized by cramping (61%, n = 705/1148), mostly starting less than 24 h prior to admission (56.7%, n = 682/1202). Interestingly, 50.9% of the patients (n = 577/1134) had atypical pain, which means pain other than epigastric or belt-like upper abdominal pain. We observed a higher proportion of peripancreatic fluid collection (19.5% vs. 11.0%; p = 0.009) and oedematous pancreas (8.4% vs. 3.1%; p = 0.016) with intense pain. Sharp pain was associated with AP severity (OR = 2.481 95% CI: 1.550-3.969) and increased mortality (OR = 2.263, 95% CI: 1.199-4.059) compared to other types. Longstanding pain (>72 h) on admission was not associated with outcomes. Pain characteristics showed little association with the patient's baseline characteristics. CONCLUSION: A comprehensive patient interview should include questions about pain characteristics, including pain type. Patients with sharp and intense pain might need special monitoring and tailored pain management. SIGNIFICANCE: Acute abdominal pain is the leading presenting symptom in acute pancreatitis; however, we currently lack specific guidelines for pain assessment and management. In our cohort analysis, intense and sharp pain on admission was associated with higher odds for severe AP and several systemic and local complications. Therefore, a comprehensive patient interview should include questions about pain characteristics and patients with intense and sharp pain might need closer monitoring.

Esophageal adenocarcinoma: What can be the cause of substantially rising incidence? / Nyelocso-adenocarcinoma: Mi lehet az oka az incidencia jelentos növekedésének?

Összefoglaló. Az 1970-es évek elott a nyelocsorákok csupán 1-3%-a volt adenocarcinoma. A 70-es évek közepétol a nyelocso-adenocarcinoma mutatta a legnagyobb növekedést az összes malignus daganat közül, és a 90-es évek közepétol már meghaladta a laphámrákok elofordulási gyakoriságát a nyugati világban. Ma a nyelocso-adenocarcinoma relatív incidenciája Magyarországon 34,7%, míg a nyugati világban már 60% körül van. A nyelocso-adenocarcinoma etiológiájában meghatároztak néhány kockázati tényezot, így a gastrooesophagealis refluxot, a Barrett-nyelocsövet, a kóros kövérséget, a dohányzást és a csökkeno Helicobacter pylori fertozöttséget. Ezek a tényezok azonban jelen voltak már a 70-es évek elott is. A kövérség elofordulásának gyakorisága és a következményes gastrooesophagealis reflux megduplázódott az elmúlt 40 évben, de ez egyedül nem magyarázza az adenocarcinomák szaporodásának ütemét. Egy új, hatékony savcsökkento gyógyszercsoportnak, a H2-receptor-blokkolóknak a bevezetésére 1976-ban került sor, és ez egybeesik a szokatlanul nagy incidencianövekedéssel. Tom DeMeester teóriája szerint a savcsökkento kezelés által létrehozott pH-változás okozhatja a refluxátum carcinogenitasának fokozódását. A Barrett-oesophagus és a nyelocso-adenocarcinoma etiológiájában, megelozésében és kezelésében számos ellentmondás és vitás kérdés tapasztalható, különösen a protonpumpagátló gyógyszerek (PPI-k) hosszú távú használata körül. A PPI-k hatásossága a gyógyszer túlzott alkalmazásához vezetett nem mindig megfelelo indikációban, kitéve a betegeket potenciális kockázatoknak. Összefoglalva, a nyelocso-adenocarcinoma drámai növekedésében biztosan szerepet játszik az elhízás és a refluxbetegség ezzel párhuzamos terjedése. Fontos továbbá a H. pylori fertozöttség csökkenése, és új szempont a hatásos savcsökkento szerek széles köru alkalmazása, melyek a refluxátumban okozott pH-változással erosíthetik a carcinogenesist. Orv Hetil. 2021; 162(51): 2040-2046. Summary. Before the 1970s, only 1-3% of esophageal cancers were adenocarcinoma. Since the mid-70s, the incidence of esophageal adenocarcinoma has shown the greatest increase compared to all other cancer types and overtook squamous carcinoma incidence in the mid-90s in the Western countries. Today, the relative incidence of esophageal adenocarcinoma in Hungary is 34.7% and around 60% in the Western countries. Some risk factors for esophageal adenocarcinoma have been identified such as gastroesophageal reflux disease, Barrett's esophagus, obesity, smoking and decreased prevalence of Helicobacter pylori infection, but these risk factors were already present before the 70s. The prevalence of obesity and the consequentially developed gastroesophageal reflux has doubled during the last 40 years, but it does not explain alone the dramatic rise in the esophageal adenocarcinoma incidence. The H2 blockers, as new effective antisecretory medication, were introduced in 1976, coinciding in time with the substantial rise of esophageal adenocarcinoma. According to the DeMeester theory, the change in the pH of gastric refluxate caused by acid suppression enhances its carcinogenic potential. There are a lot of controversies among the prevention, etiology and treatment of Barrett's esophagus and esophageal adenocarcinoma, especially regarding the long-term use of proton pump inhibitors (PPIs), an even more effective group of acid suppressors. The effectiveness of PPIs has led to an overuse exceeding its regular indications with little benefit, exposing patients to a number of potential risks. In conclusion, in the dramatic rise of the esophageal adenocarcinoma incidence, obesity accompanied by reflux disease and the decreased incidence of H. pylori infection certainly play important roles. The introduction of modern antisecretory drugs in the treatment of acid-related diseases promoting carcinogenesis, arises as a new consideration. Orv Hetil. 2021; 162(51): 2040-2046.

Esophagoplasty with hybrid-supercharged jejunum / Nyelocsopótlás hybrid, supercharged jejunummal

Introduction: In this case report an esophageal resection due to cancer was performed with a primary left colonic replacement, as the stomach was resected previously. Due to graft necrosis, the necrotized section of the colon was removed. One year later a long jejunal segment with a combined blood supply was used for secondary reconstruction. Even after the ligation of three straight branches, the Roux loop was not long enough to reach up to the neck, however the division of the arcade between the 2nd and 3rd straight branches lengthened it satisfyingly. Blood supply to the region of the farthest branch was provided from the internal mammary artery and venous drainage was provided by a saphenous vein graft to the external jugular vein. The continuity of the jejunal graft was preserved. The patient recovered uneventfully. If neither the stomach nor the colon routinely used for esophageal replacement are available due to anatomical reasons, previous surgeries, or complications, jejunal replacement can be the last resort. Jejunum is only suitable for safe esophageal replacement by either free transplantation or by supercharging. The procedure when a combined blood supply is provided for the jejunal replacement was named the hybrid-supercharged method.

Effect of SARS-CoV-2 pandemic on blood product usage at the University of Pécs / A SARS-CoV-2-pandémia hatása a vérkészítmény-felhasználásra a Pécsi Tudományegyetemen.

Összefoglaló. Bevezetés: A COVID-19-világjárvány betegellátásra gyakorolt hatása hazánkban is jelentos. A vérellátást nehezítette a járványügyi intézkedések következményeként a véradási események elmaradása, a csökkent véradási hajlandóság, továbbá a nehezen megítélheto vérkészítményigény . A "Patient Blood Management" irányelveinek az orvosi gyakorlatban történo egyre szélesebb köru alkalmazása elosegíti az optimális vérkészítmény-felhasználást a transzfúziók lehetoség szerinti elkerülésével. Célkituzés és módszer: Vizsgálatunk célja a Pécsi Tudományegyetem Klinikai Központjának Janus Pannonius Klinikai Tömbjében a vérkészítmény-felhasználás változásainak felmérése volt a 2020. év elso öt hónapjában. Eredmények: A járványügyi intézkedéseket követo idoszakban szignifikánsan csökkent a hospitalizált betegeknek (34,08%), a transzfúziót igénylo betegeknek (39,69%) és a felhasznált vörösvérsejt-készítményeknek (46,41%) a száma, valamint az egy betegre jutó felhasznált vörösvérsejt-koncentrátum átlaga (2,61-rol 1,97-re) is. Közel 30%-os arányban csökkent a felhasznált friss fagyasztott plazma egységeinek és a thrombocytakoncentrátumoknak a száma is. Következtetés: A szigorú korlátozások életbe léptetését követoen a nehézségek ellenére sikerült elegendo mennyiségu vérkészítményt biztosítani a betegeknek. Az Országos Vérellátó Szolgálat Pécsi Regionális Vérellátó Központja munkatársainak és a klinikusok erofeszítéseinek köszönhetoen a vérkészítményigény és -kínálat között új egyensúly alakult ki, mely megfelelo ellátást biztosított a feltétlenül szükséges transzfúziók kivitelezéséhez. Orv Hetil. 2021; 162(43): 1717-1723. INTRODUCTION: The impact of COVID-19 pandemic on patient care is pronounced also in Hungary. Blood supply was hindered by the reduction of public blood donation events, the reduced willingness to donate, and the difficult predictability of blood product demand as a result of the epidemiological regulations. The wider application of Patient Blood Management guidelines in the medical practice will promote optimal blood product utilization by avoiding transfusions where possible. OBJECTIVE AND METHOD: The aim of our study was to assess the changes in the usage of blood products in the first five months of 2020 at the Clinical Center of the University of Pécs, Janus Pannonius Clinical Building. RESULTS: In the period following the epidemiological measures, we found reduction in the number of hospitalized patients (34.08%), in the number of patients requiring transfusion (39.69%) and in the number of red blood cell products used (46.41%). The number of transfused red blood cell concentrates per patient was also significantly reduced (from 2.61 to 1.97) in this period. The number of transfused fresh frozen plasma units and platelet concentrates also decreased by approximately 30%. CONCLUSION: After the implementation of the strict restrictions, despite the difficulties, it was possible to provide patients with sufficient blood products. Due to the efforts of both the Regional Blood Transfusion Center of Pécs of the Hungarian National Blood Transfusion Service and of the clinicians, a new balance was established between the demand and the supply of blood products, which provided adequate care for the necessary transfusions.

A pandemic recap: lessons we have learned.

On January 2020, the WHO Director General declared that the outbreak constitutes a Public Health Emergency of International Concern. The world has faced a worldwide spread crisis and is still dealing with it. The present paper represents a white paper concerning the tough lessons we have learned from the COVID-19 pandemic. Thus, an international and heterogenous multidisciplinary panel of very differentiated people would like to share global experiences and lessons with all interested and especially those responsible for future healthcare decision making.
