Special Issue Information

Dear Colleagues,

In recent years, there have been significant advances in the diagnosis and treatment of gastrointestinal diseases, and this Special Issue aims to showcase some of the most innovative and promising approaches in this field. As gastrointestinal diseases are a broad category of disorders, the scope of this issue includes a wide range of related topics.

One area of focus is the development of new diagnostic tools and methods for detecting gastrointestinal diseases: from exploring the use of artificial intelligence and machine learning algorithms, to analyzing medical images and identifying early signs of cancer and other gastrointestinal diseases through laboratory analysis and biomarkers. Other areas of interest comprise the analysis of the microbiome to diagnose and monitor gastrointestinal diseases, the study of antimicrobial resistance, and the potential of using wearable technology to monitor patients' symptoms and vital signs in real time.

In terms of treatment, there are also exciting new developments in the gastroenterology field, such as the emergence of immunotherapy as a promising approach for gastrointestinal cancers, and researchers are exploring methods to tailor these treatments to individual patients' unique genetic and molecular profiles. Nevertheless, studies focusing on endoscopic procedures with diagnostic and therapeutic purposes are also of interest.

Background and Objectives: Diminutive polyps present a unique challenge in colorectal cancer (CRC) prevention strategies. This study aims to assess the characteristics and variables of diminutive polyps in a Romanian cohort, intending to develop a combined resect-and-retrieve or resect-and-discard strategy that reduces the need for an optical diagnosis. Materials and Methods: A prospective cohort study was conducted at two endoscopy centers in Romania from July to December 2021. Adult patients undergoing colonoscopies where polyps were identified and resected were included. Endoscopic procedures employed advanced diagnostic features, including blue-light imaging (BLI) and narrow-band imaging (NBI). Logistic regression analysis was utilized to determine factors impacting the probability of adenomatous polyps with high-grade dysplasia (HGD). Results: A total of 427 patients were included, with a mean age of 59.42 years (±11.19), predominantly male (60.2%). The most common indication for a colonoscopy was lower gastrointestinal symptoms (42.6%), followed by screening (28.8%). Adequate bowel preparation was achieved in 87.8% of cases. The logistic regression analysis revealed significant predictors of HGD in adenomatous polyps: age (OR = 1.05, 95% CI: 1.01–1.08, p = 0.01) and polyp size (>5 mm vs. ≤5 mm, OR = 4.4, 95% CI: 1.94–10.06, p < 0.001). Polyps classified as Paris IIa, Ip, and Isp were significantly more likely to harbor HGD compared to the reference group (Is), with odds ratios of 6.05, 3.68, and 2.7, respectively. Conclusions: The study elucidates significant associations between the presence of HGD in adenomatous polyps and factors such as age, polyp size, and Paris classification. These findings support the feasibility of a tailored approach in the resect-and-discard and resect-and-retrieve strategies for diminutive polyps, potentially optimizing CRC prevention and intervention practices. Further research is warranted to validate these strategies in broader clinical settings. Full article

In response to rising concerns over multidrug resistance patterns in acute cholangitis patients, this retrospective study was conducted at the Emergency County Hospital Timisoara, Romania, encompassing patients treated between August 2020 and August 2023. The study aimed to investigate the influence of prior interventions, specifically sphincterotomy (with or without stent placement), on the current clinical and microbiological profiles of acute cholangitis patients. By differentiating between patients with a history of sphincterotomy and the endoscopic retrograde cholangiopancreatography (ERCP)-naïve, we assessed the resistance of bacterial strains to antibiotics by the Tokyo Guidelines 2018, using bile cultures from 488 patients. The study identified various multidrug-resistant organisms, with a total multidrug resistance incidence of 19.9%. Significant variations were observed in the distribution of specific microorganisms and resistance patterns across different intervention groups. Patients with previous interventions, particularly those with both sphincterotomy and stent, exhibited elevated white blood cells (WBC) and C-reactive protein (CRP) levels in comparison to their ERCP-naïve counterparts. This group also presented a striking prevalence of two bacteria in their bile cultures at 50.0%, compared to 16.1% in ERCP-naïve individuals. Regarding multidrug resistance, the prior sphincterotomy with stent placement had a prevalence of 50.0%. The presence of ESBL bacteria was also significantly higher in the same group at 28.7%, contrasting with the 8.9% in ERCP-naïve patients. Additionally, the same group had a higher burden of Klebsiella spp. infections, at 37.2%, and Enterococcus spp. at 43.6%. On the antibiotic resistance front, disparities persisted. Piperacillin/Tazobactam resistance was notably more rampant in patients with a previous sphincterotomy and stent, registering at 25.5% against 11.1% in the ERCP-naïve group. This study underscores a substantial discrepancy in multidrug resistance patterns and antibiotic resistance among acute cholangitis patients with previous manipulation of the bile ducts, without expressing significant differences by the type of stent used.

Anal fistulas often cause significant impairment to patients’ health-related quality of life (HRQOL). This cross-sectional study aimed to compare the HRQOL between patients with anal fistulas with inflammatory bowel disease (IBD) and those without, hypothesizing significant differences in HRQOL scores between these groups. The secondary objectives were to identify specific aspects of life quality most affected and explore potential variables influencing HRQOL. The study was conducted at the Clinical Emergency Hospital “Pius Brinzeu” in Timisoara, Romania, using a convenience sample of 175 adult patients diagnosed with anal fistulas, stratified into IBD and non-IBD groups. Quality of life was evaluated at initial hospital admission and three months post-treatment using four questionnaires: SF-36, GIQLI, HADS, and the WHOQOL-BREF. Initial SF-36 scores were marginally lower in the IBD group, with mean physical and mental scores of 52.0 and 54.5, respectively. Both groups showed an improvement after intervention, but the mean difference was higher in the IBD group, with an increase of 1.1 in physical score. Initial GIQLI scores were significantly lower in the IBD group (110) compared to the non-IBD group (116). Post-intervention, the mean scores increased to 116 and 121, respectively. HADS scores suggested higher anxiety levels in the non-IBD group (7.5 vs. 6.1), although depression scores were similar. Post-intervention, anxiety scores decreased more substantially in the non-IBD group (−0.9 vs. −0.3). The WHOQOL-BREF scores were lower across all domains for the IBD group at the initial test (physical health: 12.4, psychological health: 14.9, social relationships: 14.4, environment: 13.0). Post-intervention, scores increased marginally in the IBD group (physical health: 12.7, psychological health: 15.9, social relationships: 14.1, environment: 13.8) but varied in the non-IBD group. HRQOL, as measured by multiple questionnaires, is impacted differently in anal fistula patients with and without IBD. These findings highlight the importance of a tailored approach to managing this patient population to improve their quality of life post-treatment. Full article

The gastrointestinal tract is home to trillions of diverse microorganisms collectively known as the gut microbiota, which play a pivotal role in breaking down undigested foods, such as dietary fibers. Through the fermentation of these food components, short-chain fatty acids (SCFAs) such as acetate, propionate, and butyrate are produced, offering numerous health benefits to the host. The production and absorption of these SCFAs occur through various mechanisms within the human intestine, contingent upon the types of dietary fibers reaching the gut and the specific microorganisms engaged in fermentation. Medical literature extensively documents the supplementation of SCFAs, particularly butyrate, in the treatment of gastrointestinal, metabolic, cardiovascular, and gut-brain-related disorders. This review seeks to provide an overview of the dynamics involved in the production and absorption of acetate, propionate, and butyrate within the human gut. Additionally, it will focus on the pivotal roles these SCFAs play in promoting gastrointestinal and metabolic health, as well as their current therapeutic implications. Full article

Surgical resection remains the cornerstone of curative treatment for intrahepatic cholangiocarcinoma (iCCA), but this option is only available to a small percentage of patients. For patients with unresectable iCCA, systemic therapy with gemcitabine and platinum-based agents represents the mainstay of treatment; however, the armamentarium has grown to include targeted molecular therapies (e.g., FGFR2 inhibitors), use of adjuvant therapy, liver transplantation in select cases, immunotherapy, and locoregional liver-directed therapies. Despite advances, iCCA remains a challenge due to the advanced stage of many patients at diagnosis. Furthermore, given the improving options for systemic therapy and the fact that the majority of iCCA patients succumb to disease progression in the liver, the role of locoregional therapies has increased. This review will focus on the expanding role of interventional radiology and liver-directed therapies in the treatment of iCCA. Full article

Thermal ablation, including microwave ablation, has become increasingly important in the management of many solid tumors, including primary and metastatic tumors of the liver, kidney, and lung. However, its adoption to treat pancreatic lesions has been slowed due to concerns about potential adverse events. The success of radiofrequency ablation (RFA) in inoperable pancreatic cancers paved the way for its use in pancreatic neuroendocrine tumors and pancreatic cystic neoplasms (PCLs). In the last decade, other thermal ablation techniques, like microwave ablation, have emerged as alternatives to RFA. Microwaves, with frequencies ranging from 900 to 2450 MHz, generate heat by rapidly oscillating water molecules. Microwave ablation’s advantage lies in its ability to achieve higher intra-lesion temperatures and uniform heating compared with RFA. Microwave ablation’s application in pancreatic cancer and pancreatic neuroendocrine tumors has demonstrated promise with similar technical success to RFA. Yet, concern for peri-procedure complications, as well as a dearth of studies comparing RFA and microwave ablation, emphasize the need for further research. No studies have evaluated microwave ablation in PCLs. We herein review thermal ablation’s potential to treat pancreatic lesions. Full article

Celiac disease (CD) is an immune-mediated enteropathy caused by exposure to gluten and related prolamins in genetically susceptible individuals. It is a complex genetic disorder with multiple contributing genes. Linkage studies have identified several genomic regions that probably contain CD susceptibility genes. The most important genetic factors are HLA-DQ2 and DQ8. Several known environmental triggers promote the onset of CD at any age after gluten introduction in individuals with a genetic background, such as viral infections and intestinal dysbiosis. Recent publications have described the interference of the intestinal microbiome in gluten metabolism, modulation of local immune reactions, and in maintaining normal gut permeability. These results have promoted further lines of research on the benefit of probiotic administration to prevent disease onset or alleviate clinical symptoms along with a gluten-free diet (GFD). The relationship between gut microbiome changes and the onset of CD is incompletely understood, still being the subject of current research. This narrative review analyzes the interplay between environmental factors, intestinal microbiome alterations, and the course of CD. Furthermore, this review sets out to discuss if modulation of intestinal microflora with pre- and probiotics along with a GFD could represent a reliable therapeutic target for celiac patients.

Background: Myocardial infarction is currently the leading cause of death worldwide, followed by malignant neoplasms. The presence of both within the same patient obviously increases the risk of death, as many coronary events are detected in patients diagnosed with cancer. Diagnosis of an occult digestive cancer in the acute phase of myocardial infarction is most frequently prompted by a hemorrhagic complication. Case summary: This case features an 81-year-old male patient diagnosed with acute myocardial infarction, treated with primary percutaneous intervention (PCI), who developed post-stenting hemorrhagic complications in the first 24 h due to the presence of two different concomitant malignant neoplasms. The outcome was favorable in the acute phase, even if de-escalation therapy was given immediately post-stenting, and intrastent residual thrombotic risk was high. Conclusions: The presence of bleeding complications in patients with acute myocardial infarction should mobilize resources in search of a neoplastic cause, especially a digestive one. However, other locations should be looked for, depending on the source of bleeding. Full article

Collision tumors, although rare, characterized by two distinctive (morphological, as well immunohistochemical) and spatially independent tumor components at the same location, are always puzzling for clinicians, pathologists, and patients because they do not fit into the usual approaches, being neither diagnostic nor therapeutic. Reviewing the specialized literature, to date, collision tumors have been reported in multiple locations such as the skin, esophagus, stomach, intestine, liver, kidney, bladder, adrenal gland, or thyroid. We report a case of coexistence at the same site of a malignant tumor of the ascending colon and a benign tumor emerging from the peritoneal lining, initially thought by the surgeon to be right-sided serosal carcinomatosis. But histopathological examination reveals that those multiple serosal nodules were benign granular cell tumors that have collided with highly aggressive transparietal signet-ring colon carcinoma. These results put the patient’s prognosis and therapeutic strategy in a different light than the clinical and intraoperative evaluation. Full article

VIPomas are a type of neuroendocrine tumor that independently produces vasoactive intestinal peptide (VIP). VIPomas causing watery diarrhea, hypokalemia, and achlorhydria (WDHA) syndrome are not frequently observed in adult patients without pancreatic ailments. However, in children, the occurrence of a VIPoma originating in the pancreas is exceedingly uncommon. Instead, WDHA syndrome is more commonly associated with neurogenic tumors that secrete VIP, often located in the retroperitoneum or mediastinum. Among infants, chronic diarrhea is a prevalent issue that often necessitates the attention of pediatric gastroenterologists. The underlying causes are diverse, and delays in arriving at a definitive diagnosis can give rise to complications affecting the overall well-being of the child. The authors present the case of an infant with chronic watery diarrhea, subocclusion manifestations, mild hypokalemia, and metabolic hyperchloremic acidosis secondary to a VIPoma in the retroperitoneum that was diagnosed via abdominal ultrasound and tomography. The laboratory results revealed lowered potassium levels and an excessive secretion of VIP. Following the surgical removal of the tumor, the diarrhea resolved, and both electrolyte levels and the imbalanced hormone levels returned to normal. Immunohistochemical examination confirmed the diagnosis of ganglioneuroblastoma, with N-MYC negative on molecular biology tests. We present the clinical and histo-genetic aspects of this rare clinical entity, with a literature review. Full article
