Intramural Hematoma of the Esophagus After Thrombolysis for Ischemic Stroke

Intramural dissecting hematoma is an unusual esophageal condition with a threatening presentation but excellent prognosis when managed conservatively.We report the case of an 88-year-old woman who developed an intramural hematoma of the esophagus after intravenous thrombolysis for an acute ischemic stroke. Before thrombolysis, nasogastric intubation was attempted unsuccessfully. She was kept on nil by mouth, intravenous hydration, proton pump inhibitor, antiemetics,and an antibiotic initiated 2 days before for periodontal disease. The esophageal hematoma regressed, and she resumed oral diet asymptomatically.To our knowledge, this is the first report of this type of lesion after thrombolysis for an ischemic stroke. A brief discussion and literature review are presented.

Endoscopic Treatment of Early Gastric Obstruction After Sleeve Gastrectomy: Report of Two Cases

Morbid obesity is an epidemic and complex disease which imposes a multidisciplinary approach. Laparoscopic sleeve gastrectomy has become a frequent procedure given its effi- cacy and safety compared to other surgical options. However, it isn’t free from complications. Lax gastric fixation or incorrect positioning of the stomach during surgery can result in early gastric outlet obstruction caused by a volvulus-like mechanism by rotation of the stomach around its anatomic axes. This report refers to two cases of post sleeve gastric torsion resulting in persisting vomiting after initiating oral intake. The diagnosis was confirmed by upper gastrointestinal-contrast study and gastroscopy. In both cases, a fully covered self-expandable metallic stentwas insertedwhich prompted the gastric lumen to become permeable resulting in symptomatic resolution. The stents were removed endoscopically aftertwo and three months. Beyond more than three years offollow-up,the patients remain asymptomatic and no recurring ‘‘stenosis’’ was noticed.In these cases the use offully covered self-expandable metallic stents demonstrated to be effective and safe in the treatment of post sleeve gastric torsion.

Colecistite Acalculosa Aguda por Salmonella Enteriditis numa Criança com Gripe A (H1N1)v

A colecistite aguda acalculosa é uma entidade pouco frequente na idade pediátrica e uma complicação rara da enterocolite por salmonelas não tifóides. A co-infecçãocom o virus influenza A (H1N1)v nunca foi previamente descrita. Caso Clinico: Rapaz de 10 anos de idade, previamente saudável, com febre elevada, cefaleias , mialgias, vómitos e diarreia. a RT-PCR para virus influenza A, subtipo H1N1v foi postiva no exsudado nasofaríngeo mas não foi prescrito oseltamivir. Ao quinto dia da doença por persistência do quadro clinico com agravamento da sintomatologia gastrointestinal recorreu à urgência. Foi internado com sinais de desidratação grave, insuficiência pré-renal aguda e oligúria, tendo-se procedido a analgesia , antipiréticos e hidratação endovenosa. Foi isolada Salmonella Enteriditis nas coproculturas. Ao 9º dia de doença houve agravamento da dor abdominal associando-se sinal de Murphy. A ecografia abdominal revelou sinais de colecistite aguda e adenopatia a comprimir infundíbulo da vesicula biliar tendo-se iniciado antibioterapia. Os sintomas persisitiram durante cinco dias, verificando-se posterior evolução clinica favorável. Discussão: A etiologia da colecistite acalculosa foi provavelmente multifatorial para a qual contribuíram a febre, a desidratação, os analgésicos, o jejum prolongado e a infecção por salmonela, cujo ciclo envolve a via biliar. A compressão pelos gânglios hipertrofiados na sequência da infecção H1N1v foi provavelmente um fator adicional, sendo questionável se a terapêutica prévia com oseltamivir teria modificado o prognóstico.
