EUS-guided hepaticogastrostomy in multimetastatic liver disease - an effective approach for biliary drainage that may complement ERCP.

A 36-year-old male was diagnosed with a metastasized colon adenocarcinoma causing obstructive jaundice. Magnetic resonance cholangiography showed a dominant lesion causing hilar stenosis. The patient was submitted to endoscopic retrograde cholangiopancreatography (ERCP), nevertheless it was just possible to place a single uncovered self-expandable metallic stent (SEMS) in the right lobe. Although cholestasis significantly improved, safe levels for oncologic therapy were not reached. EUS-guided hepaticogastrostomy was proposed to complement ERCP biliary drainage. Using a forward-viewing echoendoscope and a transgastric approach, EUS-guided puncture of a dilated left intrahepatic duct at segment III was accomplished with a 19G needle (EchoTip ProCore®) that allowed passage of a 0.035 guidewire. A 6F cystotome and biliary dilators (5Fr+8.5Fr) were used for needle tract dilation. A partially-covered SEMS (GIOBOR™ 8x100mm) could be deployed under endoscopic and fluoroscopic control, being placed 3cm inside the gastric lumen. No associated complications were observed after the procedure.

Metastatic melanoma: an uncommon cause of upper gastrointestinal bleeding.

Melanoma gastrointestinal metastases are rare and represent a late stage of malignant disease with the jejunum and ileum being the most common locations followed by stomach, colon and duodenum. We present a case of a patient with past history of cutaneous melanoma treated twelve years before, in remission. The patient developed upper gastrointestinal bleeding due to metastatic melanoma in the duodenum.

Duodenal angiolipoma: a rare tumor causing recurrent upper gastrointestinal bleeding.

Duodenal angiolipoma is a rare adipocytic tumor, with non-specific symptoms precluding an early diagnosis. We present a case of a 67-year-old female admitted due to upper gastrointestinal bleeding. The upper endoscopy and endoscopic ultrasound evaluation showed a subepithelial lesion in the third portion of the duodenum. Endoscopic excision was performed using a standard polypectomy technique after endoloop placement. Histopathology was compatible with duodenal angiolipoma. The authors highlight duodenal angiolipoma as a rare adipocytic tumor potentially causing gastrointestinal bleeding, which can be safely treated with endoscopic excision.

Fatal Case of Progressive Mpox in a Patient with AIDS-Viral Enteropathy and Malabsorption Demanding the Use of Full Parenteral ARV and Endovenous Cidofovir.

We report a fatal case of disseminated mpox infection that progressed over more than three months in an HIV-infected patient with acquired immunodeficiency syndrome (AIDS). Mucocutaneous, pleuropulmonary, central nervous system, and gastrointestinal involvement was documented. This course of disease resembles progressive vaccinia, a formerly reported disease caused by uncontrolled replication of smallpox vaccination orthopoxviruses in immunosuppressed patients. Severe small bowel involvement jeopardized normal oral tecovirimat and antiretroviral therapy absorption. This problem prompted the use of full parenteral antiretrovirals and endovenous cidofovir. Although a remarkable decrease in HIV viral load occurred in six days, mpox infection continued to progress, and the patient died of septic shock. This case offers new clinical insights on the presentation of severe disease in AIDS patients. Moreover, this case alerts for the need for prompt therapy initiation in patients at risk of ominous clinical progression.

A Case of Anti-Caspr2 Autoimmune Encephalitis Associated with Adenocarcinoma of the Lung.

Autoimmune encephalitis (AIE) is an inflammatory brain condition with multiple aetiologies but is mainly associated with paraneoplastic syndromes. Several antibodies described in AIE are being investigated in relation to different cancers, including antibodies against Contactin-associated protein-like 2 (Caspr2), which have been associated with thymoma but very rarely with lung cancer. The authors present the case of a 72-year-old man with cardiovascular risk factors, who presented with a 3-week history of left hemichorea following a first unprovoked seizure the week before, with no other signs or symptoms. The patient was submitted to extensive aetiological investigation, testing positive for anti-Caspr2 antibodies in the cerebrospinal fluid. AIE was diagnosed after other possible causes had been excluded. A PET scan showed signs of abnormal metabolism, with a lung biopsy confirming lung adenocarcinoma. This case highlights a very rare association and the importance of a thorough aetiological investigation for neurological complaints. LEARNING POINTS: Neurological complaints require a thorough aetiological investigation, and positive findings on imaging studies must be carefully examined.Anti-Caspr2 antibodies are classically associated with Morvan syndrome, but other neurological presentations must also be considered.Anti-Caspr2 autoimmune encephalitis may be the primary presentation of lung adenocarcinoma.

An Uncommon Cause of Acute Pancreatitis in a Patient With COVID-19.

Drug-induced pancreatitis is a rare though important condition that remains a diagnostic challenge. Most of the evidence relies on case reports, and clinicians should consider a high suspicion of the diagnosis after ruling out other causes. In particular, steroids are frequently used drugs that have recently been associated with acute pancreatitis. The authors present the case of a 60-year-old female admitted to the emergency room with a fever and shortness of breath. The SARS-CoV-2 test was positive, and the chest radiography was suggestive of COVID-19 pneumonia. The patient started dexamethasone because of respiratory failure. On Day 7, she developed epigastric pain radiating to the back and the amylase level was greater than 10 times the upper reference limit (1354 U/L). A detailed evaluation of the medical history, along with the exclusion of other possible etiologies confirmed the diagnosis of steroid-induced pancreatitis. Supportive care and cessation of the offending drug led to the resolution of symptoms. As steroids are used as part of the treatment of most COVID-19 patients, this case suggests the need to consider this entity, as a delay in the diagnosis may result in complications and prolonged hospital stay.

Pyogenic Liver Abscess and Delayed Massive Gastrointestinal Bleeding Following Endoscopic Retrograde Cholangiopancreatography (ERCP): Association of Two Rare Complications.

A liver abscess (LA) is the most common type of visceral abscess. While biliary tract disorders are its most common etiology, clinicians should also consider less frequent causes such as iatrogenic complications due to certain interventions. One of these unusual causes is related to endoscopic retrograde cholangiopancreatography (ERCP) with endoscopic sphincterotomy (ES), a usually safe procedure that carries some risk of complications. We present the case of a 71-year-old female with a history of choledocholithiasis who underwent ERCP with ES without any immediate complications; she was discharged after 24 hours and readmitted three days later to the emergency room with fever and abdominal pain. An abdominal CT showed a liver abscess. Blood cultures were positive for Escherichia coli, Streptococcus anginosus, and Enterococcus faecalis, and the patient was started on directed antibiotic therapy with ampicillin, benzylpenicillin, and metronidazole. On day 17, due to hematochezia with hemodynamic instability, an urgent upper gastrointestinal endoscopy was performed, which revealed late post-ES bleeding, refractory to conventional endoscopic therapy. An ERCP was performed to control the bleeding by using a biliary fully covered self-expandable metal stent (FCSEMS), which was removed four weeks later. The follow-up CT showed a significant reduction of LA and the patient was discharged. This case highlights the association of two uncommon complications of ERCP: a LA and a major late post-ES bleeding. Clinicians should maintain a high index of suspicion for these complications in daily practice.

Clinical Nutrition in Portuguese Gastroenterology Departments: A Multicentric Study.

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.
