    Abstract Intraductal papillary mucinous neoplasms (IPMN) play an important role mongst exocrine tumours of the pancreas due to several causes. Although they count for only 1% of all the tumours, they represent some 20-30% of all cystic neoplasms, a histologically defined group that has gained a lot of attention lately. IPMNs of the main or the secondary (branch) pancreatic ducts have remarkably different rates of malignant transformation, prognosis and thus indication for surgery. Prognosis of a ductal carcinoma developing from IPMN does not differ from classic ductal adenocarcinoma, with a very poor (10%) 5-year survival rate. However, prognosis of IPMN can still be regarded favourable, because the above rate can be as high as 70% if the tumour is non-invasive. This fact leads to the importance of diagnosing and resecting IPMN before its malignant transformation into an invasive carcinoma.

    Abstract Colorectal cancer (CRC) is the third most common malignant tumor and resection remains the key element in its treatment. The correction of preoperative malnutrition reduces morbidity and mortality. Our study demonstrates a nutritional state mass screening protocol to steer nutritional support. Two hundred fifty-nine patients with planned colorectal resection were prospectively enrolled. Preoperative telemedicinal assessment determined the risk of malnutrition using Nutritional Risk Screening 2002 (NRS 2002) score. Patients with a score ≥3 were offered optimized oral nutritional supplement. Three groups were investigated. Group I (NRS 2002 < 3,

    Titelübersetzung Tartós SARS-CoV-2-PCR-pozitivitáshoz társuló, lokoregionálisan előrehaladott emlődaganat komplex onkológiai kezelése.
    Abstract Összefoglaló. A COVID-19 mortalitását a súlyos társbetegségek, közöttük bizonyos daganatos betegségek is növelik. Immunszuppresszív hatásuk miatt felmerülhet a citotoxikus kezelések rizikónövelő hatása is. Ugyanakkor az onkológiai terápia megszakítása vagy halasztása, különösen az agresszívebb, kiterjedtebb és fiatalkorban jelentkező daganatok esetében ronthatja a kórjóslatot. Egy 39 éves nőbeteg esetét ismertetjük. A járvány során késlekedve felismert, lokoregionálisan kiterjedt emlődaganat miatt primer szisztémás kemoterápiában részesült. A kezelés 5. ciklusa során enyhe légúti tünetek kapcsán, az onkológiai ambulancián SARS-CoV-2-fertőzése igazolódott. Kemoterápiás kezelését felfüggesztettük. A diagnózistól számított 3. napon tünetmentessé vált, ám SARS-CoV-2-PCR-pozitivitása még a 43. napon is fennállt. A 19. napon hormongátló kezelést indítottunk. Az 51. napon mastectomia és axillaris block dissectio történt. A 82. napon a megszakított kemoterápiát a hormongátló kezelés leállítását követően G-CSF-profilaxis mellett újraindítottuk. A kezelés során fertőzéses szövődményt nem észleltünk. Kemoterápia és műtét SARS-CoV-2-fertőzött, tünetmentes daganatos betegnél szövődménymentesen végezhető elhúzódó virológiai pozitivitás esetén, felszabadító vizsgálat nélkül is. A daganatos betegek koronavírus-fertőzése esetén az onkológiai protokolltól történő eltérés egyénre szabott optimalizálásával és a multidiszciplináris team szorosabb együttműködésével az infektológiai és az onkológiai kockázat együttes alacsonyan tartása is megvalósítható. Orv Hetil. 2021; 162(16): 611-614. Summary. Mortality of COVID-19 is increased when certain co-morbidities, among others advanced malignancies are present. Deleterious effect of cytotoxic therapy, related to its immunosuppressive effect, may also be hypothesised. However, postponing or cancelling oncologic treatment, especially in younger patients with advanced and more aggressive tumors may worsen the prognosis. The case of a 39-year-old female patient is presented, who was diagnosed with loco-regionally advanced breast cancer during the pandemic. Primary systemic chemotherapy was started. The patient presented with acute respiratory tract symptoms during the fifth cycle and subsequently SARS-CoV-2 infection was diagnosed. Chemotherapy was cancelled. Symptoms resolved in three days after diagnosis. SARS-CoV-2 PCR remained positive up to day 43. Antihormonal therapy was introduced on day 19 and she underwent mastectomy with axillary lymph node dissection on day 51. Chemotherapy was reset postoperatively on day 82 with prophylactic G-CSF protection. No adverse event was observed throughout the treatment. Cytotoxic chemotherapy and surgery can be successfully delivered in breast cancer patients with prolonged asymptomatic SARS-CoV-2 PCR positivity, even without negative swab result. Individual optimisation of the therapy may require deviations from standard protocols. Closer multidisciplinary cooperation may contribute to the minimisation of both oncologic and infectious risks.

    Titelübersetzung Diagnosis and management of blunt pancreatic trauma.
    Abstract The management of thoracic and abdominal organ injuries has very thorough and extensive literature, including evidence-based protocols. Pancreatic trauma stands as an exception. Blunt or penetrating trauma of the pancreas is rather rare (less than 2% of all trauma cases, approximately 3-12% of all abdominal trauma), leading to the lack of high-level evidences regarding its treatment. Damage of the pancreas parenchyma can cause substantial morbidity and mortality, therefore it is essential to separate cases where conservative treatment suffices from those that need surgical approach. This study aims to review the conclusions of relevant articles of the past decades concerning the management of both adult and childhood pancreatic trauma. Classifications and their reliability are revised. We enlist scaling systems that can help in making decision whether to operate or to treat conservatively, from physical examination to diagnostic measures and complications. To date, the treatment principles of pancreatic trauma are not based either on prospective or on randomised trials. The database search of studies retrieved only retrospective and/or small case cohorts, case reports and expert opinions (levels 4 and 5 of evidence). However, it is a generally accepted conviction that the damage of the main pancreatic duct determines if the pancreatic injury is of low or high grade. Available classifications are based on the same principle. Conservative treatment is feasible given that the patient is hemodinamically stable and the pancreatic duct is unimpaired. If duct lesion is discovered, adult cases are to be treated with minimally invasive (percutaneous or endoscopic) measures or surgically (including reconstruction, resection and drainage). The management of childhood injuries has controversial literature. Many arguments can be enumerated on the operative as also on the non-operative approach, this confusion is to be clarified in the future. The highest morbidity rates are derived from the late diagnosis of the pancreatic duct, while increased mortality is seen in the polytrauma patient groups. Levels 1-2 evidence-based recommendations are needed, but planning of strong trials is critically limited due to the small number of cases and the heterogeneity of the relevant patient groups.

    Abstract Background: There is no consensus regarding the role of mechanical bowel preparation (MBP) and oral antibiotic prophylaxis (OABP) in reducing postoperative complications in colorectal surgery. The aim of this study was to examine the effect of OABP given in addition to MBP in the setting of a prospective randomized trial.
    Methods: Patients awaiting elective colorectal surgery in four Hungarian colorectal centres were included in this multicentre, prospective, randomized, assessor-blinded study. Patients were randomized to receive MBP with or without OABP (OABP+ and OABP- groups respectively). The primary endpoints were surgical-site infection (SSI) and postoperative ileus. Secondary endpoints were anastomotic leak, mortality, and hospital readmission within 30 days.
    Results: Of 839 patients assessed for eligibility between November 2016 and June 2018, 600 were randomized and 529 were analysed. Trial participation was discontinued owing to adverse events in seven patients in the OABP+ group (2.3 per cent). SSI occurred in eight patients (3.2 per cent) in the OABP+ and 27 (9.8 per cent) in the OABP- group (P = 0.001). The incidence of postoperative ileus did not differ between groups. Anastomotic leakage occurred in four patients (1.6 per cent) in the OABP+ and 13 (4.7 per cent) in the OABP- (P = 0.02) group. There were no differences in hospital readmission (12 (4.7 per cent) versus 10 (3.6 per cent); P = 0.25) or mortality (3 (1.2 per cent) versus 4 (1.4 per cent); P = 0.39).
    Conclusion: OABP given with MBP reduced the rate of SSI and AL after colorectal surgery with anastomosis, therefore routine use of OABP is recommended.
