RESUMEN
OBJECTIVES: Portal hypertensive polyps (PHPs) are incompletely characterized lesions that can be found in the distal stomach of patients with portal hypertension. We aimed to delineate clinical factors associated with the appearance of these rare polyps. MATERIAL AND METHODS: We conducted a cross-sectional study of a cohort with 513 cirrhotic patients comparing patients with and without PHP using descriptive analyses and multivariable logistic regression. To address the problem of missing values, in particular for HVPG and liver stiffness, we used multiple imputation of missing values. RESULTS: The prevalence of macroscopically diagnosed PHP was 3.3% (95% confidence interval 2.0 - 5.4%). In 53% of cases, the correct classification was missed on index gastroscopy. Patients with PHP were older at gastroscopy (65 years vs. 59), had higher hepatic venous pressure gradients (HVPG, 28 mmHg vs. 19 mmHg), higher transient elastography (TE) measurements (50.7 kPa vs. 21.8 kPa) and more often had previous rubber band ligations (RBL, 64.7% vs. 25.8%). The multivariable logistic regression on the outcome macroscopically diagnosed PHP estimated an odds ratio (OR) for HPVG of 1.13 (CI 0.95-1.34), increased liver stiffness of 1.03 (1.00 - 1.07) and previous RBL of 3.84 (1.24 - 11.88), respectively. CONCLUSION: The prevalence of PHPs in the stomach was higher than assumed in previous studies and misclassification was commonly observed. The appearance of these rare polyps is associated with previous RBL and may correlate with severity of PH. Thus, PHPs may be regarded as marker for relevant PH, but clinical significance of these polyps is still uncertain.

Single water swallow (SWS) high-resolution manometry (HRM) may miss relevant esophageal motility disorders. Solid test meal (STM) during HRM and lately the functional lumen imaging probe (FLIP) have been shown to be of diagnostic value in the assessment of motility disorders. We aimed to assess the diagnostic yield of STM and FLIP in non-obstructive dysphagia (NOD). Patients assessed for dysphagia with both HRM and FLIP between April 2016 and August 2019 were analyzed for signs of non-obstructive EGJ outflow obstruction (EGJOO) according to Chicago Classification 3.0 (CCv3) and CC adapted for the use with solid swallows (CC-S), followed by an individual group-specific analysis. Five subjects without dysphagia served as control group. Standard HRM- and FLIP-values as well as esophagograms and Eckardt Scores were analyzed. Forty-two patients were identified (male/female, 14/36, median age 62). Twenty-five (59.5%) were diagnosed with EGJOO during STM only (= SWS-negative patients; CC-S). The EGJ distensibility index (EGJ-DI) of symptomatic patients was significantly lower compared to the control group (p = 0.006). EGJ-DI was < 3mm2/mmHg in 67% and 88% of patients diagnosed according to CC-S and CCv3, respectively. The IRP during STM showed a significant association to the corresponding EGJ-DI values (p < 0.001). Seventy-six percent of patients received treatment because of additional STM evaluation with a favorable clinical response rate of 89%. STM and FLIP identify EGJOO in symptomatic patients with normal SWS during HRM. STM resembles an inexpensive and clinically meaningful option to diagnose motility disorders and helps to select patients for interventional treatment.

BACKGROUND AND AIMS: The role of decreased pyloric distensibility in gastroparesis as measured by the endolumenal functional luminal imaging probe (EndoFLIP) has been receiving increasing attention. In this study, we present clinical outcomes to pyloric dilation with the esophageal FLIP (EsoFLIP) in regard to gastric emptying, symptom evolution, and FLIP metrics. METHODS: Patients evaluated for gastroparesis (gastric emptying studies of t1/2 ≥180 minutes during 13C-octanoic acid breath test and/or gastric remnants during gastroscopy after a sufficient fasting period) were scheduled for EsoFLIP controlled pyloric dilation. Pre- and postprocedural gastric emptying studies, questionnaires (Patient Assessment of Upper GI Symptoms Severity Index [PAGI-SYM; including the Gastroparesis Cardinal Symptom Index] and Patient Assessment of Quality of Life Index [PAGI-QOL]), and FLIP metrics were documented. Dilation was conducted according to a self-developed algorithm. RESULTS: Forty-six patients were analyzed (72% women; median age, 39 years [range, 18-88]). Etiologies of gastroparesis were diabetic in 10 patients (22%), idiopathic in 33 (72%), and postoperative in 3 (6%). Postprocedural gastric emptying time decreased from a median of 211 minutes to 179 minutes (P = .001). In accordance, pyloric distensibility, PAGI-SYM, PAGI-QOL, and Gastroparesis Cardinal Symptom Index values improved significantly. After a median follow-up of 3.9 months, 57% of all treated patients with returned questionnaires reported improved symptoms. CONCLUSIONS: Pyloric EsoFLIP controlled dilation shows value in the treatment of gastroparesis, both subjectively and objectively. Long-term follow-up to assess efficacy and comparative trials are warranted.

BACKGROUND AND AIM: Previous studies have shown a reduction of gastrointestinal symptoms in irritable bowel syndrome (IBS) patients following a low FODMAP diet (LFD). It remains unknown which disorders of gut-brain interaction (DGBI) patients would benefit most from LFD. We aimed to analyze LFD response regarding a preceding nutrient challenge test (NCT). METHODS: Data of 110 consecutive DGBI patients undergoing NCT and LFD between August 2015 and August 2018 were analyzed retrospectively. LFD response was assessed by changes in IBS Symptom Severity Score (IBS-SSS). In mixed-effects linear regression models, the impact of hydrogen values and abdominal symptoms during NCT, performed with 30-g lactulose and 400-mL liquid test meal, on IBS-SSS changes were analyzed. RESULTS: Low FODMAP diet induced a significant IBS-SSS reduction of 78 points (95% confidence interval [CI] 50-96; P < 0.001). Patients with higher NCT-induced hydrogen increase during proximal intestinal transit had a significantly better LFD response (-66 IBS-SSS reduction per 10-ppm hydrogen increase, 95% CI -129 to -4, P = 0.045). Additionally, the higher the NCT-induced maximum hydrogen increase during mid-distal and distal intestinal transit, the better are the responses to LFD (-6 IBS-SSS per 10-ppm maximum delta hydrogen, 95% CI -11 to -1, P = 0.040). There was no association of LFD response with abdominal symptom generation during NCT. CONCLUSIONS: Our study is the first one analyzing and demonstrating significant associations between NCT results and LFD response. These findings are of high clinical importance, as they identify a subgroup of DGBI patients that may profit most from a restrictive LFD as first-line therapy.

BACKGROUND AND STUDY AIMS: Alveolar echinococcosis, an orphan zoonosis affecting the liver, is of increasing concern worldwide. Most symptomatic cases present at an advanced and inoperable stage, sometimes with biliary obstruction prompting biliary tract interventions. These are, however, associated with a high risk of infectious complications. The aim of this retrospective study was to compare the effectiveness and safety of conservative and interventional treatment approaches in patients with newly diagnosed alveolar echinococcosis and biliary obstruction. PATIENTS AND METHODS: Alveolar echinococcosis patients treated at two referral centres in Switzerland, presenting with hyperbilirubinaemia (total bilirubin >1.5 Upper Limit of Normal) at diagnosis were included, unless another underlying aetiology, i.e. common bile duct stones or decompensated cirrhosis, was identified. Patients were divided into two groups, according to whether they initially received a biliary tract intervention. The primary endpoint was normalisation of bilirubin levels within a 6-month period. Secondary endpoints included, among others, the occurrence of early and late biliary complications, the need for biliary tract interventions during follow-up and overall duration of hospital stays for treatment initiation and for biliary complications. RESULTS: 28 patients were included in this study, of whom 17 received benzimidazole therapy alone and 11 additionally received a biliary tract intervention. Baseline characteristics did not differ between groups. All but one patient in each group achieved the primary endpoint (p=0.747). Biliary tract intervention was associated with faster laboratory improvement (t1/2 1.3 vs 3.0 weeks), but also with more frequent early biliary complications (7/11 vs 1/17, p=0.002) and longer initial hospital stay (18 days vs 7 days, p=0.007). CONCLUSION: Biliary obstruction in patients with newly diagnosed alveolar echinococcosis can be treated effectively with benzimidazole therapy alone. Biliary tract intervention, on the other hand, is associated with a high complication rate and should probably be reserved for patients with insufficient response to benzimidazole therapy.

Background: Treatment of refractory ascites remains challenging. We evaluated the safety and efficacy of permanent tunneled peritoneal catheters (PTPC) in this condition. Methods: We retrospectively analyzed consecutive patients in palliative situations in a tertiary referral center. Safety parameters, symptom relief, and survival were assessed. Results: Seventy patients were included from February 2012 to January 2021. Ninety percent had ascites due to malignancy, 10% due to end-stage liver disease. The technical procedure was successful in all cases; no deaths occurred. Procedure-related infections were rare and only observed in patients without peri-interventional antibiotics. Most patients experienced symptom relief (76%) and were satisfied with the device (83%). Survival after PTPC was relatively short (median 19 days). Discussion: PTPC is a safe option for refractory ascites in palliative settings with symptom relief in the majority of patients and should be considered early after onset of ascites. Periprocedural antibiotic prophylaxis may be considered to avoid procedure-related infections.

We report the case of a 63-year-old female patient with liver cirrhosis who presented with symptoms of severe hypoalbuminaemia and diarrhoea. After ruling out other causes of hypoalbuminaemia and confirmation of an elevated faecal α-1 antitrypsin clearance, the diagnosis of protein-losing enteropathy (PLE) could be established. Since PLE is a syndrome caused by various diseases, classified into erosive and non-erosive gastrointestinal diseases or lymphatic obstruction, an extensive work-up was necessary, establishing the final diagnosis of Crohn's disease.

OBJECTIVE: While single sugar tests are controversially discussed, combination tests with meals are gaining more attention. The aim of this study was to analyze the impact of adding a test meal to lactulose hydrogen breath tests (LHBT) on hydrogen values and abdominal symptoms in patients with functional gastrointestinal disorders (FGIDs). METHODS: Data of 81 FGID patients between 2014-2018 were analyzed. Patients underwent LHBT with 30 g lactulose + 300 mL water and a nutrient challenge test (NCT) including 400 mL liquid test meal + 30 g lactulose. To statistically assess the effect of a test meal on abdominal symptoms and H2, mixed-effect models were used. RESULTS: Adding a test meal to LHBT showed a significant increase in nausea [odds ratio (OR) 1.4; 95% confidence interval (CI), 1.1-1.7], decrease in abdominal pain (OR 0.7; 95% CI, 0.6-0.9), borborygmi (OR 0.5; 95% CI, 0.4-0.6), diarrhea (OR 0.4; 95% CI, 0.3-0.6), and H2 production (estimate -5.3, SE 0.7, P < 0.001). The effect on bloating was only significant in functional dyspepsia, irritable bowel syndrome-functional dyspepsia mixed type and functional abdominal pain/bloating (OR 0.1; 95% CI, 0.0-0.2; OR 1.7; 95% CI, 1.2-2.3 resp OR 4.4; 95% CI, 1.8-10.6). CONCLUSIONS: Significant effects on abdominal symptoms and H2 production by adding a test meal to LHBT in FGID patients are shown. Increased occurrence of nausea may be caused by gastric/duodenal hypersensitivity; decreased H2, diarrhea and borborygmi by slower and more physiologic gastric emptying resulting in later arrival of the test substance in the bowel. We recommend NCTs instead of LHBT to more physiologically represent FGID patients' meal-induced burden.

Enteral feed bezoars are difficult to treat and can lead to serious adverse events. There is no standardized treatment approach and various strategies have been suggested. We herein describe three cases of successful dissolutions of feed bezoars consisting of Promote® Fibre Plus with sodium bicarbonate 8.4% in critically ill patients. To provide the rationale for this approach, the effect of sodium bicarbonate 8.4% on enteral feed concretions was studied in vitro. First, Promote® Fibres Plus was incubated with hydrochloric acid with gradually decreasing pH values to establish a pH at which the solution solidifies. The resulting enteral feed concretion was exposed to sodium bicarbonate 8.4% and Coca Cola®. All patients were successfully treated with sodium bicarbonate 8.4% without the need of lengthy or repeat endoscopies. In vitro, Promote® Fibres Plus solidifies when acidified below a pH of 4.6. The resulting enteral feed concretions dissolved when exposed to sodium bicarbonate 8.4%. Incubation with Coca Cola® had no effect. We provide evidence that enteral feed bezoars consisting of Promote® Fibres Plus can be efficiently and safely treated with sodium bicarbonate 8.4% offering a new approach for daily patient care.

BACKGROUND: Achalasia is a chronic esophageal motility disorder characterized by impaired relaxation of the lower esophageal sphincter, determined by an elevated integrated relaxation pressure (IRP > 15 mm Hg) and absent peristalsis. Goal of treatment is facilitation of flow across the EGJ but minimizing postinterventional reflux. A new advanced hydraulic dilation technology, the esophageal functional luminal imaging probe (EsoFLIP), allows dynamic monitoring of hollow organ dimensions while performing hydraulic dilation. The aim of our study was to evaluate the treatment response after single EsoFLIP dilation in achalasia patients. METHODS: Dilation was performed under endoscopic control with the EsoFLIP device using a self-developed dilation algorithm. Symptom scores were assessed by the Eckardt score (ES) before and 1-4 weeks after intervention. Esophageal emptying before and after intervention was recorded with timed barium esophagogram. KEY RESULTS: We studied 28 consecutive untreated achalasia patients (8 female) with a median age of 43 years (range 19-82 years) undergoing their first dilation performed with the EsoFLIP, aiming at a maximum dilation diameter of 25 mm. Total ES was significantly reduced from 7 at baseline to 2 postintervention (P < .001). The median height of the barium column after 5 minutes was significantly reduced from 4.5 cm at baseline to 1.7 cm (P = .0087). No major complications occurred. CONCLUSIONS & INFERENCES: We found good efficacy in both subjective and objective short-term treatment outcome after singular EsoFLIP dilation in treatment-naive achalasia patients. Our findings suggest that EsoFLIP is a promising dilation technology that should be further studied in a larger, controlled setting with longer follow-up.
