Summary

Gastrointestinal disease is a very common and frequently occurring disease, with a wide range of types and a total incidence of about 20% of the population. The cause of gastrointestinal disease is the imbalance between the protective mechanism and the injury mechanism of the human body. While traditional medicine kills harmful bacteria in the stomach, it also kills the beneficial bacteria necessary for the stomach. Although the symptoms are alleviated and inflammation is eliminated, the reduction of beneficial bacteria reduces the gastrointestinal immunity. Once the drug is stopped, it is easy to re-infect. There are many reasons for stomach problems, including genetics, environment, diet, drugs, bacterial infections, etc., as well as smoking and excessive alcohol consumption. This collection of entries aims to collect various items related to the topic of gastrointestinal diseases, such as clinical care, case cases, disease research, etc., to help people increase their knowledge and understanding of this common disease

Diet for Gut Microbiota and Dyslipidemia
Diet is understood to be the most important determinant in shaping the microbiota ecosystem as balanced diets of fruits and vegetables are shown to increase gut bacterial richness and diversity. As such, lifestyle changes specifically through dietary interventions represent an effective therapeutic modality for dyslipidemia by creating targeted and beneficial changes in gut microbial composition. Although many dietary choices influence the composition of the gut microbiota, two particular diets have been studied extensively and can lead to significant, yet opposite effects. In this section, the metabolic changes seen in Western Diet (WD)-induced dyslipidemia followed by the role of plant-based diets was first described,  such as the Mediterranean diet (MD) play in optimizing gut microbial composition to restore defective metabolic states.

The Mediterranean Diet and Inflammatory Bowel Diseases
The Mediterranean diet is considered one of the healthiest dietary patterns worldwide, thanks to a combination of foods rich mainly in antioxidants and anti-inflammatory nutrients. Many studies have demonstrated a strong relationship between the Mediterranean diet and some chronic gastrointestinal diseases, such as inflammatory bowel diseases.

Role of Endoscopy in Upper Gastrointestinal Cancers
Upper gastrointestinal (GI) malignancy is a leading cause of cancer-related morbidity and mortality. Upper endoscopy has an established role in diagnosing and staging upper GI cancers, screening for pre-malignant lesions, and providing palliation in cases of advanced malignancy. New advances in endoscopic techniques and technology have improved diagnostic accuracy and increased the therapeutic potential of upper endoscopy.

Secondary Primary Cancer after Primary Gastric Cancer
Advances in cancer screening and early detection, as well as improvements in surgical techniques and therapeutics, have contributed to decreasing gastric cancer mortality. The number of gastric cancer survivors continues to rise; however, long-term follow-up has revealed an increase in the risk of post-gastrectomy symptoms or other health problems, such as extra-gastric secondary primary cancer (SPC), in these survivors. The characteristics of SPC are of increasing interest to both treatment providers and gastric cancer survivors.

Field of Submucosal Endoscopy
Submucosal endoscopy (third-space endoscopy) can be defined as an endoscopic procedure performed in the submucosal space. This procedure is novel and has been utilized for delivery to the submucosal space in a variety of gastrointestinal diseases, such as a tumor, achalasia, gastroparesis, and subepithelial tumors. The main submucosal endoscopy includes peroral endoscopic myotomy, gastric peroral endoscopic myotomy, Zenker peroral endoscopic myotomy, submucosal tunneling for endoscopic resection, and endoscopic submucosal tunnel dissection. Submucosal endoscopy has been used as a viable alternative to surgical techniques because it is minimally invasive in the treatment and diagnosis of gastrointestinal diseases and disorders.

Deep Learning in Liver Transplantation
Liver transplantation outcomes have improved. Looking for the best Donor-Recipient matching (D-R matching) as always been a challenge for the liver transplantation surgeons. Most of the proposed scores based on conventional biostatistics are not good classifiers of a problem that is considered “unbalanced.” The implementation of artificial intelligence in medicine has experienced exponential growth. Deep learning, a branch of artificial intelligence with capability to handle a large number of variables with speed and multi-objective analysis. Artificial neural networks and random forests are the most widely used deep-learning classifiers in this field. Both classifiers have been able to show a high predictive ability in the graft survival of a D-R pair compared to traditional classifiers. There are even researchers that have successfully created a matching model based on one of them.

R1 Resection of LIver Metastas in Colorectal Cancer
 Achieving an R0 hepatic resection, optimally with more than 1 mm of clear margin, should always be the goal. In the era of the aggressive multimodality treatment of liver metastatic colorectal cancer, an R1 resection might be the cost of increasing the pool of patients finally eligible for resection. The majority of literature reports have highlighted the detrimental effect of R1 resections on local recurrence and overall survival. There are indeed studies that degraded the prognostic handicap as a consequence of an R1 resection in selected patients and highlighted the presence of RAS mutations, the response to chemotherapy, and, in general, factors that reflect the biology of the disease as important, if not the determinant, prognostic factors. In these patients, the aggressive disease biology seems to outperform the resection margin status as a prognostic factor, and the recorded differences between R1 and R0 resections are equalized.

Interstitial Cells of Cajal
The interstitial cells of Cajal (ICC) represent a particular network formed by some peculiar cells that were first described by the great neuroanatomist, S. Ramon y Cajal. The ICC have become a fascinating topic for scientists, arousing their curiosity; as a result, there is a vast number of published articles related to the ICC. Everybody widely accepts that the ICC represent the pacemaker of the gastrointestinal tract and are highly probable to be the origin cells for gastrointestinal tumors (GISTs).

Diagnostic Methods in H. pylori Infection
Helicobacter pylori (H. pylori) develops potentially life-threatening conditions in adults if not appropriately treated. Helicobacter pylori is a common human pathogen that was first described in the stomach many years ago.

Extracellular Vesicles as a Biomarker in Liver Disease
Extracellular vesicles (EVs) are membrane-derived vesicles released by a variety of cell types, including hepatocytes, hepatic stellate cells, and immune cells in normal and pathological conditions. Depending on their biogenesis, there is a complex repertoire of EVs that differ in size and origin. EVs can carry lipids, proteins, coding and non-coding RNAs, and mitochondrial DNA causing alterations to the recipient cells, functioning as intercellular mediators of cell–cell communication (auto-, para-, juxta-, or even endocrine). The use of EVs as biomarkers in liver disease development are described.
