Background: Roux-en-Y reconstruction excludes the afferent limb and the biliopancreatic system from conventional endoscopic access. Postoperative problems in these excluded gastrointestinal systems are therefore often dealt with surgically. We investigated the usefulness of the therapeutic double-balloon enteroscope to perform interventional endoscopic procedures in the excluded segment of the gastrointestinal tract after Roux-en-Y reconstruction. Methods: 30 procedures were performed in 22 patients with Roux-en-Y reconstruction after enterobiliary anastomosis, gastrectomy or bariatric gastric bypass. All procedures were performed with the therapeutic double-balloon enteroscope, under general anesthesia and with fluoroscopic control. Results: ERCP at the enterobiliary anastomosis was successful in 90% (n = 10) of the procedures. ERCP at the intact papilla was successful in 60% (n = 5). Enterocutaneous fistula closure after (sub)total gastrectomy was performed in 2 procedures. Successful diagnostic procedures encompassed intubation of the excluded stomach after bariatric gastric bypass (89%, n = 9) or the afferent limb after Roux-en-Y reconstruction (75%, n = 4). The overall success rate in accessing the aimed excluded segment with the double-balloon enteroscope was 87%. Interventional procedures were able to avoid surgery in 65%. One retroperitoneal perforation occurred during ERCP which was conservatively treated. Conclusions: Excluded gastrointestinal segments after Roux-en-Y reconstruction can be accessed with a substantial success rate using double-balloon enteroscopy. Therapeutic interventions like ERCP can prevent surgery in the majority of patients.

Faced with difficulty discriminating between placenta and myometrium in a patient with three previous caesarean sections, MRI provided definitive diagnosis of caesarean scar pregnancy, allowing for a save and uneventful planned surgical procedure.

Laparotomy was scheduled a few days later, and a bowel-like mass was found, which did not connect with the gastrointestinal tract and its mesentery. Enteric duplications are non-malignant, rare (1:4500) congenital anomalies that may vary greatly in presentation, size, location and symptoms. Associated anomalies are common; screening is appropriate.3 Thus, infected enteric duplication cysts are rare, but should be considered in the differential diagnosis of unidentified abdominal mass with signs of obstruction and/or infection.

Purpose The aim of this study is to evaluate whether previously reported post-mortem CT findings in drowning can reliably distinguish drowning from asphyxiation by any other manner. Materials and methods Cases ( n  = 14) were corpses with cause of death determined as drowning by concordant autopsy findings and physical and circumstantial evidence. Controls ( n  = 11) were corpses in which the cause of death was defined as asphyxiation by any other manner than submersion in a liquid. Images were evaluated for the presence of fluid in paranasal sinuses, mastoid air cells and lower airways, frothy foam in the upper airways, ground-glass opacity of the lung parenchyma, the height of the right hemi-diaphragm, the interpulmonary distance at the level of the aortic valve, the mean density of intracardiac blood, and gastric and esophageal contents. Descriptive statistics, Fisher’s exact test, and Student’s t test were used when appropriate. Results Only the height of the right hemi-diaphragm differed significantly ( p  = 0.045) between cases (mean 5.4) and controls (mean 4.3). Other findings were not significantly different between both groups. Conclusion Our results indicate that it is not possible to reliably distinguish drowning from non-drowning asphyxiation on CT, because many findings in drowning were also present in non-drowning asphyxiation. CT indicators for drowning as the cause of death should therefore be defined with great caution, keeping in mind that they are not specific to only a single cause of death.

We describe two neonates with a liver abscess after umbilical venous catheterisation. The first case was a female neonate, born at 32 weeks of gestation. After persistence of elevated inflammatory parameters, an abscess in the right lobe of the liver was diagnosed. Percutaneous drainage under CT guidance was performed. The aspirated pus grew Staphylococcus epidermidis. Inflammatory parameters normalised after 27 days of antimicrobial therapy (vancomycin, cefotaxim, rifampicin). The second case was in a male neonate, born at 29 weeks of gestation. Percutaneously aspirated pus from the liver abscess was cultured and remained sterile. The patient received antimicrobial therapy (vancomycin, cefotaxim, amikacin) for 26 days and was cured with conservative treatment. hepatic abscess should be considered in any infant with an umbilical catheter-associated sepsis and persistent inflammatory response in spite of adequate antimicrobial therapy, especially when signs of abdominal infection are present.

Cell therapies, including tumor antigen-loaded dendritic cells used as therapeutic cancer vaccines, offer treatment options for patients with malignancies. We evaluated the feasibility, safety, immunogenicity, and clinical activity of adjuvant vaccination with Wilms’ tumor protein (WT1) mRNA-electroporated autologous dendritic cells ( WT1 -mRNA/DC) in a single-arm phase I/II clinical study of patients with advanced solid tumors receiving standard therapy. Disease status and immune reactivity were evaluated after 8 weeks and 6 months. WT1 -mRNA/DC vaccination was feasible in all patients, except one. Vaccination was well tolerated without evidence of systemic toxicity. The disease control rate and overall response rate among a total of 39 evaluable patients were 74.4% and 12.8%, respectively. Median overall survival (OS) was 43.7 months among 13 patients with glioblastoma multiforme, 41.9 months among 12 patients with metastatic breast cancer, and 48.8 months among 10 patients with malignant pleural mesothelioma, comparing favourably with historical controls reported in the literature. OS was longer in patients with stable disease at 8 weeks and disease control at 6 months versus patients without disease control at either time point. Disease control and higher OS were associated with antigen-specific type 1 CD4 + and/or CD8 + T-lymphocyte responses, mainly induced by WT1 -mRNA/DC vaccination. Antigen-nonspecific type 2 CD8 + T-cell responses were common before WT1 -mRNA/DC vaccination but did not show any association with clinical outcome. Collectively, these data indicate that WT1 -mRNA/DC vaccination is feasible, safe, and immunogenic and shows clinical activity in patients with advanced solid tumors, suggesting that it has the potential to help improve their survival.

The ESO-ESSO-ESTRO Multidisciplinary Course in Oncology is intended to fill the gap of the undergraduate fragmented oncology education, to provide insight into all theoretical and practical aspects of oncology, and to encourage future professional choices towards an oncology discipline. Students are exposed to (a) preclinical cancer topics; (b) natural history of the disease; (c) laboratory diagnostic tests; (d) medical, radiation, surgical, and palliative treatment; and (e) direct or through multidisciplinary patients’ approach. Students are obliged to attend (i) all theoretical lectures, (ii) clinical case presentations, (iii) laboratories and ward visits, and (iv) to prepare and present a specific project under supervision. Participation is limited to 24 medical students who are selected through a competitive application process. Between 2016 and 2019, 96 students from 29 countries have attended. Data analysis derived from a given questionnaire demonstrates that most of the participants have declared that (1) they have achieved their expectations and objectives, (2) they have highly rated both clinical and non-clinical teaching oncological topics, and (3) they have been stimulated in developing a professional career in the field of oncology.

We report a 3.5-month-old boy with polysplenia syndrome who demonstrated hemiazygos continuation of the inferior vena cava, extrahepatic biliary atresia, multiple splenunculi, bowel malrotation, and the rare finding of brainstem and cerebellar hypoplasia. A possible pathogenesis for cerebellar hypoplasia in this syndrome is suggested after review of the literature. The importance of seeking associated anomalies in biliary atresia, which may be possible indicators of polysplenia syndrome, is stressed since these patients need appropriate management when surgery is considered.

Somatostatin receptor (SSTR) imaging with gallium 68 (Ga-68) 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA)-peptide positron emission tomography/computed tomography (PET/CT) has been introduced in clinical routine for the diagnosis and staging of neuroendocrine tumors (NETs) with high SSTR expression. Although it has high sensitivity for NETs, there are some known diagnostic pitfalls one should be aware of. We present a case of suspected NET where Ga-68 DOTA-NaI3-octreotide (NOC) PET/CT showed several abdominal lesions with high SSTR expression suggesting malignancy. On magnetic resonance imaging, the differential diagnosis of the lesions also included splenosis. Subsequent splenic scintigraphy with technetium-99m phytate showed uptake in all suspicious lesions, and biopsy confirmed the diagnosis of splenosis. Splenic scintigraphy with single-photon emission computed tomography/CT can be a helpful noninvasive diagnostic tool when splenosis is suspected on Ga-68 DOTA-peptide PET/CT.
