Chronic Intestinal Failure and Short Bowel Syndrome in Adults: The State of the Art.

Background: Short bowel syndrome (SBS) is a devastating malabsorptive condition and the most common cause of chronic intestinal failure (CIF). During the intestinal rehabilitation process, patients may need parenteral support for months or years, parenteral nutrition (PN), or hydration/electrolyte supplementation, as a bridge for the desired enteral autonomy.

Summary: Several classification criteria have been highlighted to reflect different perspectives in CIF.

Steroid-Refractory Acute Severe Ulcerative Colitis in Infliximab-Experienced Patients.

Acute severe ulcerative colitis (ASUC) is a potentially life-threatening complication of ulcerative colitis (UC) that can lead to significant morbidity and mortality, with a substantial number of patients needing colectomy. Infliximab (IFX) has been increasingly used as a rescue therapy for patients who have failed intravenous steroids and has been more frequently used as an induction and maintenance therapy in moderate-to-severe UC. Therefore, the number of patients admitted with ASUC previously exposed to IFX has been increasing, raising additional challenges in the medical management of these patients to avoid emergent colectomy.

Malignancy and mass-forming phenotypes of IgG4-related disease: a challenging diagnosis.

Mass-forming phenotypes of IgG4-related disease (IgG4-RD) mimic malignancy and histological confirmation can be challenging. A woman in her 70s with HIV infection presented with painless obstructive jaundice and weight loss. Magnetic resonance imaging was suggestive of unresectable cholangiocarcinoma.

Quality of death in patients in advanced chronic liver disease and cancer patients managed by gastroenterologists in Portugal: are we doing it right?

Introduction: The incidence of chronic progressive diseases is rising and investment on quality of death and dying is of utmost importance to minimize physical and emotional suffering. There is still a gap in palliative care (PC) between patients with cancer and those with advanced chronic liver disease (ACLD). Our objectives were to characterize clinical attitudes and therapeutic interventions and to evaluate the differences in end-of-life care between inpatients with cancer and ACLD under gastroenterology care.

Narrow Band Imaging versus White Light for the Detection of Sessile Serrated Colorectal Lesions: A Randomized Clinical Trial.

Background: Colorectal cancer (CRC) is a leading cause of cancer. The detection of pre-malignant lesions by colonoscopy is associated with reduced CRC incidence and mortality. Narrow band imaging has shown promising but conflicting results for the detection of serrated lesions.

Doomed for carcinomatosis? An unusual presentation of abdominal tuberculosis.

A 35-year old male from Brazil presented with intermittent abdominal pain. Abdominal computed tomography revealed a nodule adjacent to splenic hilum and multiple abdominal nodules, suspicious of carcinomatosis. The patient underwent gastroscopy and endoscopic ultrasound (EUS), that revealed an ill-defined hypoechogenic lesion adjacent to the spleen and two hypoechogenic subepithelial lesions located in the 4th layer of the stomach and duodenal bulb.

Early intervention with biologic therapy in Crohn´s disease: how early is early?

Background: Early biologic therapy within the first 18-24 months after diagnosis is associated with improved clinical outcomes in Crohn's disease [CD]. However, the definition of the best time to initiate biologic therapy remains unclear. We aimed to assess if there is an optimal timing for early biologic therapy initiation.

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).

Groove Pancreatitis: Clinical Cases and Review of the Literature.

Introduction: Groove pancreatitis (GP) is a type of chronic segmental pancreatitis that affects the pancreatoduodenal groove area, and it is often misdiagnosed. Outflow obstruction of the minor papilla associated with alcohol consumption seems to be the main pathophysiological mechanism, and it affects mainly middle-aged males. Symptoms include nausea and postprandial vomiting from gastric outlet obstruction, weight loss, and abdominal pain.

Aggressive Colorectal Cancer in an Inflammatory Bowel Disease Patient following Treatment with Vedolizumab: A Case Report.

Introduction: The increased risk of bowel cancer in patients with inflammatory bowel disease can be related with the extent, duration and severity of inflammation or with the cancer immune surveillance interference of immunosuppressive drugs used in inflammatory bowel disease treatment. Therefore, the risk-benefit ratio associated with long-term therapeutic strategies should be based on the patient's age, sex, comorbidities and disease phenotype.

Case Report: We present the case of a 76-year-old man with a history of melanoma stage Clark III and steroid-dependent left-sided colitis, refractory to mesalamine and thiopurines, with a diagnosis of a multifocal colorectal adenocarcinoma shortly after clinical and endoscopic remission 1 year after starting vedolizumab.

Secondary Sclerosing Cholangitis in a Critically Ill Patient with Severe SARS-CoV-2 Infection: A Possibly Emergent Entity during the Current Global Pandemic.

A 46-year-old woman without previous history of hepatobiliary disease was admitted to the intensive care unit due to SARS-CoV-2 infection. Admission blood tests revealed impending hyperinflammation in the context of systemic inflammatory response syndrome. She required 12 days of mechanical ventilation and vasopressor support.

Inflammatory Bowel Disease Patients' Perspectives during COVID-19 Pandemic: Results from a Portuguese Survey.

Introduction: Patients with inflammatory bowel disease (IBD) do not seem to be at increased risk of infection by SARS-CoV-2, but there is a concern whether immunosuppressive therapy may be associated with more severe disease. Several clinical practice recommendations have been published to help guide IBD care during the COVID-19 pandemic. Nonetheless, few studies have addressed patients' perspectives and fears.

Participation in clinical trials increases the detection of pre-malignant lesions during colonoscopy.

Background: colorectal adenoma detection has been associated with the effectiveness of cancer prevention. Clinical trials have been designed to determine the role of several interventions to increase the detection of pre-malignant lesions. We hypothesized that colonoscopy in the setting of clinical trials has a higher pre-malignant lesion detection rate.

COVID-19 in Gastroenterology Departments: The Impact of the First Wave.

Introduction: Coronavirus disease 2019 (COVID-19) is a global pandemic that has severely affected health care systems around the world. During the emergency state declared in Portugal in the months of March and April 2020, there was a severe reduction in medical activity in order to reduce the pressure on health systems. This study aimed to assess the impact of COVID-19 in gastroenterology departments across Portugal and the strategies developed to overcome this challenge.

Preoperative enteral nutrition in adults with complicated Crohn's disease: Effect on disease outcomes and gut microbiota.

Objectives: The use of exclusive enteral nutrition (EEN) in patients with Crohn's disease (CD) before surgical resection can reduce disease activity and improve nutritional status. The mechanism of EEN action is unclear, but it might involve modulation of the intestinal microbiota. The aim of this study was to evaluate the effects (namely changes in gut microbiota) of preoperative EEN in adults with complicated CD referred to surgery.

Adenoma Detection Rate: I Will Show You Mine if You Show Me Yours.

Background: Colorectal cancer (CRC) is the first cause of cancer-related mortality in Portugal. CRC screening reduces disease-specific mortality. Colonoscopy is currently the preferred method for screening as it may contribute to the reduction of CRC incidence.

Trends in net survival from stomach cancer in six European Latin countries: results from the SUDCAN population-based study.

Gastric cancers are a clinical challenge. The aim of the SUDCAN collaborative study was to compare the net survival from gastric cancer between six European Latin countries (Belgium, France, Italy, Portugal, Spain and Switzerland) and explore the trends in net survival and in the dynamics of the excess mortality rates (EMRs) up to 5 years after diagnosis. The data were extracted from the EUROCARE-5 database.

Non-anesthesiologist administration of propofol sedation for colonoscopy is safe in low risk patients: results of a noninferiority randomized controlled trial.

Background And Study Aims: Propofol provides the best sedation in colonoscopy. The safety of non-anesthesiologist administration of propofol (NAAP) is still a matter of debate. The aim of the current study was to evaluate sedation safety, colonoscopy quality, and patient satisfaction with NAAP.

Acute lower gastrointestinal bleeding management in Portugal: a multicentric prospective 1-year survey.

Introduction: Acute lower gastrointestinal bleeding (ALGIB) is a common event, which consumes considerable human and economic resources. Its incidence is expected to rise in the coming years due to an increasing aging population.

Patients And Methods: Multicentric prospective analysis of patients was carried out with ALGIB in 13 Portuguese hospitals from April 2008 to May 2009, using a protocol designed by the French Association Nationale des Hépato-Gastroentérologues des Hôpitaux Généraux.
