Introduction

Malnutrition, sarcopenia, and frailty constitute the three vertices of a nutrition-status-determined physio-pathological triangle constantly featuring and dramatically burdening the prognosis of advanced chronic liver disease (ACLD) patients.
Dysgeusia is defined by a distortion of the sense of taste whose prevalence, relationship with the progression of the disease, and the direct contribution to malnutrition (and consequently, sarcopenia-frailty) in ACLD have never been systematically explored.

Aims & Methods

This observational study aimed to explore the prevalence of dysgeusia in a cohort of ACLD patients and evaluate the impact of this disorder on appetite levels and nutritional status (malnutrition, sarcopenia, and frailty), as well as to prospectively estimate the repercussions of dysgeusia-induced impaired nutritional status on liver-related events (LREs) occurrence. For this purpose, 40 controls, 50 chronic-liver disease-affected individuals staging initial-mild fibrosis (<F3), and 150 ACLD patients of various etiologies were enrolled. Anthropometrical, biochemical, clinical, and nutritional [European Prospective Investigation into Cancer and Nutrition (EPIC) questionnaire] data were collected. The opportunely modified Chemotherapy-induced Taste Alteration Scale (CITAS) questionnaire was used to assess the dysgeusia. Child-Pugh (CP) and Liver Frailty Index (LFI) calculations, Liver Stiffness Measurement (LSM), and Bioelectrical Impedance Analysis (BIA) were performed. Skeletal Muscle Mass (SMM) index (SMMI) (SMM/height²) < 7 kg/m² (male) and < 5.7 kg/m² (female) defined sarcopenia. ACLD patients were 3 years followed up semiannually and LREs (including ascites, hepatic encephalopathy, and bleeding) were collected.

Results

The prevalence of dysgeusia was significantly higher in ACLD (68%) in comparison to <F3 (8%) individuals and controls (5%) and in decompensated ACLD (dACLD) than compensated (cACLD) (54% vs 6%) patients (all p<0.0001). In line, CITAS-dysgeusia severity positively correlated with CP (R:0.81), as well as with the levels of appetite impairment (R:0.93) (both p<0.0001). Logistic regression analysis, appropriately weighted for factors notoriously impacting food intake in ACLD patients (low-sodic diet, drugs/supplements taken, physical activity frequency, occurrence of encephalopathy and ascites episodes in the previous 2 weeks), revealed the level of impairment of the appetite as a factor significantly associated with dysgeusia [HR: 2.12; p:0.02]. Compared to no-dysgeusia-affected dACLD (p:0.03), dysgeusia-affected dACLD patients (dys-dACLD) showed a decreased daily protein intake, reduced Free Fat Mass % (p<0.0001), and SMMI (p<0.0001: p:0.04), in contrast with increased LFI (p<0.0001). Consistently, dys-dACLD patients showed a higher prevalence (59% vs 39%) of sarcopenia (p:0.0002). The Kaplan-Meier Log-Rank Test analysis on LREs occurrence showed HR:3.53 [95% C.I: 1.58-4.92] for dys-dACLD individuals.

Conclusion

The prevalence of dysgeusia, increasing in parallel to the worsening of liver disease, promoted sarcopenia-frailty pictures, negatively influencing ACLD patients' outcomes.

Introduction

Complete excision of upper gastrointestinal sub-epithelial lesions (SELs) eliminates diagnostic uncertainty, obviates the need for surveillance and may be necessary for definitive diagnosis and management. Current guidelines lack precision and cohesion, and surgery is associated with significant morbidity. Herein, we describe and report on the outcomes of our SEL algorithm for endoscopic (SAFE) resection.

Aims & Methods

SELs were enrolled prospectively over 115 months until March 2023. All underwent axial (CT) imaging and endoscopic-ultrasonography (EUS) to exclude a large exophytic component or invasion into local structures, and assess for muscularis propria involvement.

Results

106 SELs were resected (mean age 60.6±13.4, 51.9% male; 41 oesophageal, 65 gastric). Oesophageal SELs underwent ESD (n=22) or STER if MP involvement was suspected (n=19). Gastric SELs underwent STER (n=6 at cardia), ESD (n=47) or exposing-EFTR (n=12). Technical success was 97.6% and 92.3% respectively. Five (7.7%) were completed laparoscopically due to deep and broad full-thickness involvement. Five (7.7%) required laparoscopic gastrotomy and surgical retrieval after successful resection and closure due to a large lesion size (mean 47 mm). There was no delayed bleeding, perforation or recurrence at a median of 13 months.

Conclusion

Upper GI SELs are effectively and safely treated by endoscopic resection. The SAFE approach provides a framework that facilitates structured decision-making. Oesophageal SELs suspected to involve the MP should undergo STER. Gastric SELs can be best managed by ESD with a view to proceed to exposing-EFTR. A laparoscopic UGI surgeon should be available in case surgical retrieval of the specimen or laparoscopic completion is required.

Introduction

Upper gastrointestinal bleeding (UGIB) remains one of the major emergencies. However, predicting the presence and degree of UGIB before endoscopy is still inaccurate. Therefore, the development of an accurate and non-invasive method is required. The purpose of this study was to discover potential metabolic biomarkers for UGIB using an in vitro digestion model, liquid chromatography-mass spectrometry (LC-MS) and gas chromatography-mass spectrometry (GC-MS).

Aims & Methods

Blood samples from 30 healthy volunteers were collected. To simulate UGIB , blood samples underwent either simulated gastric phase in vitro digestion (Blood + simulated gastric fluid (SGF)) or both simulated gastric and intestinal phase (Blood + SGF + simulated intestinal fluid (SIF)). Using untargeted metabolomics approaches with LC-MS and GC-MS metabolomic profiles and volatile organic compounds (VOC) profiles of digested blood were analyzed. Compounds that distinguish between undigested blood and digested blood were sorted out to screen potential biomarkers for UGIB.

Results

From the LC-MS analysis of the undigested blood (Control) and digested blood; blood that was digested with SGF (Blood + SGF) and blood that was digested with both SIF and SGF (Blood + SGF + SIF), a total of 47 metabolites were identified. The levels of 42 (7 from Blood + SGF and 37 from Blood + SGF + SIF) metabolites had significantly higher levels (p < 0.05, Log2(FC) > 2) in the digested blood as compared to the Control.
By analyzing extracted VOCs respectively in Control groups and metabolized samples(Blood+SGF and Blood + SGF + SIF) through GC-MS, 16 compounds were identified as statistically significant. Among them, three compounds appeared at higher levels in the Blood + SGF than the Control(p<0.05, Log2(FC) > 2). In addition, three compounds showed higher levels in the Blood + SGF + SIF than the Control.

Conclusion

With metabolomic approaches, we have detected 63 statistically significant compounds (47 compounds by LC-MS, 16 compounds by GC-MS). Specific features with the considerable possibilities to be biomarkers for UGIB were found. Through in-depth understanding of metabolic pathways and further investigation in clinical settings, discovered features could be utilized to diagnose UGIB in an accurate and non-invasive manner.

Introduction

Endoscopic retrograde cholangiopancreatography (ERCP) is a minimally invasive endoscopic procedure that is crucial for pancreato-biliary diseases and selective cannulation is the most important step. However, even an experienced endoscopist can face cannulation failure in up to 15-30% of cases in the first ERCP when standard methods alone are used.¹ Many studies suggested the various needle knife fistulotomy or papillotomy as an alternative technique in difficult cannulation cases.^2,3 However, needle knife papillotomy (NKP), which is modified technique with needle knife has not been evaluated well.

Aims & Methods

To evaluate the clinical outcomes and adverse events of bile duct cannulation by NKP, we performed a retrospective review on medical records of all ERCP cases in Sheikh Khalfia Specialty Hospital, UAE. For six years, Sphincterotomy (SPT) naïve patients except altered-anatomy cases were enrolled and their procedure times, cannulation success rates, radiation exposures, and adverse events were measured between the procedure time matched two cohort group of SPT only and rescue NKP.

Results

In total 416 ERCP cases, 43 procedure time matched cases were selected among 352 (84.7%) SPT only cohort and 43 cases from 64 rescue NKP cohort. Biliary cannulation was succeeded in all cases (100%) by using SPT cannulation with rescue NKP technique without failure. There was no differences in cumulative radiation doses, cannulation time, and adverse event rates in rescue NKP group compared to SPT only group: Post-ERCP hyperamylasemia/hyperlipasemia (16.5% vs. 34.8%, p=0.080), pancreatitis (3.9% vs. 4.3%, p=0.883), cholangitis (4.7% vs. 4.3%, p=0.695), and no perforation case was noticed in both groups.

Conclusion

The SPT with rescue NKP technique can be used in the difficult biliary cannulation cases during ERCP safely and effectively.
