ABSTRACT
Mycotic aortic aneurysm is a rare entity, manifesting with nonspecific symptoms of abdominal pain, fever, general malaise. We present a case of an 83-years-old-man, with hematemesis, generalized abdominal pain, and a six-month history of constipation, anorexia, and involuntary weight loss. Upper endoscopy revealed an erosion with oozing hemorrhage and hemostasis was performed. Later he developed a hemorrhagic shock. Abdominal computed tomography disclosed a 3,7x2,5x- 2,5cm aneurysm of the abdominal aorta with an aortoduodenal fistula, inducing an inflammatory plastron that encompassed the descending colon and duodenum. The inflammatory plastron prompted partial duodenal and colonic obstruction and led to an atypical presentation of an aortic aneurysm. Mycotic aneurysms complicated with aorto-enteric fistulas are potentially life-threatening conditions. We highlight the rarity of this case, as the clinical manifestations were prolonged and atypical. The goal is to drive awareness to maintain a high clinical suspicion, as early detection is critical to avoid a tragic outcome.

BACKGROUND: Hospital nutrition is a major public health problem, as up to 50% of hospitalized patients suffer from undernutrition. Adequate nutritional support (NS) decreases morbidity/mortality, shortens the length of stay, and reduces costs. We aimed to evaluate the engagement of Portuguese gastroenterology departments in NS, especially in artificial nutrition (AN). METHODS: Cross-sectional multicentric study, using an online survey sent to 31 Portuguese gastroenterology departments. RESULTS: Nine centers were involved, and all departments were engaged in NS activities. The most performed nutrition technique was endoscopic gastrostomy and not all departments had the expertise to perform all nutrition procedures, namely, endoscopic jejunostomy. Two departments had an AN outpatient clinic. Five centers were involved in hospital nutrition committees. Only four performed systematic nutritional evaluation of every patient on admission. Two departments developed research in the nutrition field. An increase staff and nutrition training were pointed out as suggestions to improve NS. CONCLUSIONS: This study outlines a broad picture of NS/AN in Portuguese gastroenterology departments. Medical nutritional training and increasing nutrition teams' staff may contribute to developing NS/AN. Multidisciplinary management of nutrition-related disorders is of utmost importance, and gastroenterologists are expected to be at the core of hospital nutrition.

Benign biliary strictures comprise a heterogeneous group of diseases. The most common strictures amenable to endoscopic treatment are post-cholecystectomy, post-liver transplantation, related to primary sclerosing cholangitis and to chronic pancreatitis. Endoscopic treatment of benign biliary strictures is widely used as first line therapy, since it is effective, safe, noninvasive and repeatable. Endoscopic techniques currently used are dilation, multiple plastic stents insertion and fully covered self-expandable metal stents. The main indication for dilation alone is primary sclerosing cholangitis related strictures. In the vast majority of the remaining cases, temporary placement of multiple plastic stents with/without dilation is considered the treatment of choice. Although this approach is effective, it requires multiple endoscopic sessions due to the short duration of stent patency. Fully covered self-expandable metal stents appear as a good alternative to plastic stents, since they have an increased radial diameter, longer stent patency, easier insertion technique and similar efficacy. Recent advances in endoscopic technique and various devices have allowed successful treatment in most cases. The development of novel endoscopic techniques and devices is still ongoing.
ABSTRACT
Actinomycosis is a rare disorder caused by an anaerobic gram-positive bacillus (Actinomyces), predominantly by the Actinomyces israelii species. Only 20% of cases show an abdominal manifestation, the appendix and ileocecal valve being the most frequent locations. Definitive diagnosis is based on microbiological cultures, microscopy or macroscopy examination. Nevertheless, histological examination of the percutaneous biopsy and blood microbiological cultures are rarely positives. Preoperative diagnosis is hampered by the lack of specific clinical and imaging manifestations, which often mimic malignancy. The rate of preoperative diagnosis is less than 10%, however, the outcome is excellent, with a low mortality rate. The authors describe the case of a patient who was diagnosed with primary hepatic actinomycosis only by a histological examination of the surgical specimen of left hepatectomy extended to segments V and VIII, for suspected malignant lesion. This case demonstrates the difficulties in diagnosing hepatic actinomycosis.
A actinomicose é uma entidade clínica rara, causada por uma bactéria anaeróbia gram-positiva (Actinomyces), predominantemente da espécie Actinomyces israelii. Apenas em 20% dos casos apresenta manifestação abdominal, sendo o apêndice e a válvula ileocecal as localizações mais frequentes. Os autores descrevem o caso de um doente em que foi feito o diagnóstico de actinomicose hepática primária apenas pelo exame histológico da peça cirúrgica de hepatectomia esquerda alargada aos segmentos V e VIII, por suspeita de lesão maligna. Este caso demonstra a dificuldade diagnóstica da actinomicose hepática. O diagnóstico pré-operatório é dificultado pela falta de manifestações clínicas e imagiológicas específicas, muitas vezes simulando doença maligna. Para além disso, as culturas e o exame histológico de biópsia percutânea raramente são positivos. A taxa de diagnóstico pré-operatório é inferior a 10%, contudo o prognóstico é bom, apresentando uma taxa de mortalidade de cerca de 7,6%.
