Endoscopic ultrasound-guided drainage of a pelvic abscess - An alternative use of lumen-apposing metallic stents.

The use of lumen-apposing metal stent is well defined for endoscopic ultrasound-guided drainage of pancreatic collections (e.g. WON). However, it is not yet a well-established approach in the management of postsurgical collections. We present an alternative application of LAMS for EUS drainage of pelvic abscess, showing that it is a safe and minimally invasive technique, with excellent clinical results. This technique should be considered as a drainage alternative in these scenarios due to its lower morbidity and mortality, opening a new era in the approach to these lesions.

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.

Predictors for incomplete response to ursodeoxycholic acid in primary biliary cholangitis. Data from a national registry of liver disease.

BACKGROUND: The current standard of treatment in primary biliary cholangitis (PBC) is ursodeoxycholic acid (UDCA), although a considerable proportion of patients show incomplete response resulting in disease progression. OBJECTIVE: This study aimed to assess the prevalence of incomplete response to UDCA and determine associated patients' characteristics. METHODS: Patients with PBC as main diagnosis were included from a national multicentric patient registry-Liver.pt. Main endpoints included incomplete response to UDCA treatment according to Barcelona, Paris I and Paris II criteria, Globe and UK PBC scores and the association between baseline characteristics and incomplete response according to Paris II criteria. RESULTS: A total of 434 PBC patients were identified, with a mean age of 55 years and 89.2% females. Nearly half of patients were asymptomatic at diagnosis and 93.2% had positive anti-mitochondrial antibodies. Almost all patients (95.6%) had been prescribed at least one drug for PBC treatment. At the last follow-up visit, 93.3% were under treatment of which 99.8% received UDCA. Incomplete response to UDCA was observed in 30.7%, 35.3%, 53.7% and 36.4% of patients according to Barcelona, Paris I, Paris II criteria and Globe score, respectively. After adjusting for age and sex, and accordingly to Paris II criteria, the risk for incomplete biochemical response was 25% higher for patients with cirrhosis at diagnosis (odds ratio [OR] = 1.25; 95% confidence interval [95%CI]: 1.02-1.54; p = 0.033) and 35% (95%CI:1.06-1.72; p = 0.016) and 5% (OR = 1.05; 95%CI:1.01-1.10; p = 0.013) for those with elevated gamma-glutamyl transferase (GGT) and alkaline phosphatase (ALP). CONCLUSION: A considerable proportion of patients showed incomplete biochemical response to UDCA treatment according to Paris II criteria. Cirrhosis, elevated GGT and ALP at diagnosis were identified as associated risk factors for incomplete response. Early identification of patients at risk of incomplete response could improve treatment care and guide clinical decision to a more careful patient monitorization.

Hepatic osteodystrophy in cirrhosis due to alcohol-related liver disease.

INTRODUCTION: hepatic osteodystrophy, including osteoporosis, is an abnormal bone metabolism related with chronic liver diseases. Osteoporosis is associated with an increased risk of bone fractures, with a significant impact on morbidity, mortality and healthcare costs. Nevertheless, bone disorders tend to be undervalued in cirrhosis due to alcohol-related liver disease (ALD cirrhosis). This study aimed to assess the prevalence of hepatic osteodystrophy and osteoporosis in ALD cirrhosis. METHODS: a prospective observational study was performed that included patients with ALD cirrhosis, between September 2017 and December 2018. Bone mineral density was determined by dual energy X-ray absorptiometry at the lumbar spine and the femoral neck. Hepatic osteodystrophy was defined as a T-score below -1 SD and osteoporosis as a T-score below -2.5 SD. RESULTS: ninety-four patients were included; 24.5 % (n = 23) had prior fragility fractures and ten patients suffered new osteoporotic fractures during the study period. Hepatic osteodystrophy was diagnosed in 79.8 % (n = 75) and osteoporosis in 21.3 % (n = 20) of cases. Patients with hepatic osteodystrophy presented significantly worse Child-Turcotte-Pugh (p < 0.05) and Model for End-Stage Liver Disease (MELD-sodium) scores (p = 0.01). According to the multivariate analysis, lower body mass index (BMI) (OR = 0.787, 95 % CI: 0.688-0.901, p = 0.001) and vitamin D deficiency (OR = 6.798, 95 % CI: 1.775-26.038, p = 0.005) were significantly and independently associated with hepatic osteodystrophy. Patients with osteoporosis also had a lower BMI (p = 0.01). Female patients and those with prior fragility fractures were more likely to suffer from osteoporosis (p < 0.05). CONCLUSION: our study revealed a high prevalence of hepatic osteodystrophy and osteoporosis in patients with ALD cirrhosis (particularly in those with a lower BMI) and a concerning high rate of fragility fractures. Bone mineral density should be assessed in order to allow for an early diagnosis and the implementation of preventive measures.

Should patients with symptomatic cholelithiasis before 30 years of age be tested for ABCB4 gene mutations?

BACKGROUND AND AIMS: Low phospholipid-associated cholelithiasis syndrome (LPAC) is characterized by recurrent symptomatic cholelithiasis in young adults associated with ABCB4 gene mutations. Current diagnosing criteria are complex and heterogeneous, making this a largely underdiagnosed entity. Also, although recommended, genetic testing is not necessary for the diagnosis and its real advantages are not clear. The aim of our study was to explore the prevalence of ABCB4 mutations in symptomatic patients with cholelithiasis before the age of 30. METHODS: We conducted a multicentric prospective cohort study including patients with symptomatic cholelithiasis presenting before 30 years of age in 4 Portuguese centres between January 2017 and December 2019. ABCB4 gene was analyzed by next generation sequencing (NGS) including all exons and flanking regions. In 17/32 patients ABCB11 and ATP8B1 variants were also analyzed by NGS. RESULTS: Thirty-two patients were included (75% females, median age of symptom onset was 23 ± 5 years). We found that 8/32 (25%) patients had mutations in ABCB4 gene, 3/17 (18%) in ATP8B1 gene and 1/17 (6%) in ABCB11 gene. 44% (8/18) of patients with LPAC syndrome criteria had identified variants, while the prevalence of mutations in patients with symptoms onset before 30 as sole criteria was 29%. CONCLUSION: Our results suggest that LPAC should be systematically suspected and investigated in patients with symptomatic cholelithiasis before age of thirty, but genetic testing should only be attempted in patients complying with the more stringent LPAC criteria.

A rare case of diarrhea and ascites.

BACKGROUND: Eosinophilic enterocolitis is a rare condition included in the spectrum of the eosinophilic gastrointestinal disorders. Diagnosis is based on clinical presentation combined with an increase infiltration of eosinophils in the gastrointestinal tract, in the absence of other secondary causes of eosinophilic infiltration. CASE PRESENTATION: We report a case of a 22-year-old male with eosinophilic enterocolitis presenting with malabsorption syndrome (diarrhea, vomiting, weight loss), bowel wall thickening, and ascites. Secondary causes of intestinal eosinophilia were excluded, and diagnosis was established in a timely manner. Treatment plan included a 6-food elimination diet and corticosteroid therapy, with clinical remission after 2 weeks of therapy. The patient remains asymptomatic after 12 months of follow-up, with no relapse.
