Background: Several locoregional treatments approaches, including thermoablation, have been tested for the treatment of intrahepatic cholangiocarcinoma (ICC) and have shown encouraging results. However, data are heterogeneous in terms of tumor number, size, and ablation technique. Objective: The aim of this study was to investigate the efficacy and prognostic factors in ICC treated by monopolar radiofrequency (RF) or microwave ablation (MW). Methods: This was a retrospective study including patients treated with RF or MW for ICC in six participating centers. DFS and OS were evaluated by the Kaplan–Meier method and prognostic factors by log-rank test and Cox modeling. Results: From January 2015 to October 2023, 24 patients with 31 nodules were treated with RFA or MW. Overall, 70% had chronic liver disease, with 50% at cirrhosis stage. The median size of lesions was 17 mm (6–35 mm). After a median follow-up of 33 months (5–85), the median DFS was 10.5 months. The median OS was 40.8 months. On univariate and multivariate analysis, only lesion size > 17 mmwas associated with a poor OS (HR 3.09; IC [1.02; 9.37] (p = 0.04). Conclusions: Monopolar radiofrequency or microwave ablation is an alternative to surgery for small ICCs. Tumors < 17 mm were associated with better OS....
This study reviews the recent progress of generative artificial intelligence for gastrointestinal disease (GID) from detection to diagnosis. The source of data was 16 original studies in PubMed. The search terms were ((gastro* [title]) or (endo* [title])) and ((GAN [title/abstract] or (transformer [title/abstract]). The eligibility criteria were as follows: (1) the dependent variable of gastrointestinal disease; (2) the interventions of generative adversarial network (GAN) and/or transformer for classification, detection and/or segmentation; (3) the outcomes of accuracy, intersection of union (IOU), structural similarity and/or Dice; (3) the publication period of 2021–2023; (4) the publication language of English. Based on the results of this study, different generative artificial intelligence methods would be appropriate for different tasks for the early diagnosis of gastrointestinal disease. For example, patch GAN (accuracy 91.9%) in the case of classification, bi-directional cycle GAN (structural similarity 98.8%) in the case of data generation and semi-supervised GAN (Dice 89.4%) in the case of segmentation. Their performance indicators reported varied within 87.1–91.9% for accuracy, 83.0–98.8% for structural similarity and 86.6–89.4% for Dice. Likewise, vision transformer (accuracy 96.9%) in the case of classification, multi-modal transformer (IOU 79.5%) in the case of detection and multi-modal transformer (Dice 89.5%) in the case of segmentation. Their performance measures reported registered a variation within 85.7–96.9% for accuracy, 79.5% for IOU and 77.8–89.5% for Dice. Synthesizing different kinds of generative artificial intelligence for different kinds of GID data would further the horizon of research on this topic. In conclusion, however, generative artificial intelligence provides an effective, non-invasive decision support system for the early diagnosis of gastrointestinal disease from detection to diagnosis....
Background/Objectives: Lymphocytic esophagitis is a rare inflammatory disease of the esophagus, first described in 2006. Since that time, interest in this disease entity has steadily increased, yet specific data on the etiology of the disease are still lacking. Lymphocytic esophagitis co-occurs with esophageal motility disorders, Crohn’s disease, hypersensitivity (allergy, asthma), the use of certain medications, or immune disorders. Risk factors include smoking and alcohol abuse. The disease is more prevalent in women, developing predominantly within the sixth decade of life. The most important symptom is dysphagia, with odynophagia, epigastric, and chest pain or heartburn being less common. No particular endoscopic presentation is pathognomonic for lymphocytic esophagitis, the findings not infrequently resembling those of eosinophilic esophagitis. Conclusions: There is great need for an international consensus defining strict histopathological criteria for the diagnosis of lymphocytic esophagitis as well as relevant diagnostic and therapeutic management. This review paper presents the current state of knowledge on lymphocytic esophagitis....
Acute upper gastrointestinal hemorrhage is a highly prevalent clinical condition, with the majority of cases representing acute non-variceal upper gastrointestinal hemorrhage. With the advancement of modern medicine, endoscopy has become an indispensable tool in the diagnosis and treatment of various diseases. In order to achieve optimal results in the endoscopic treatment of non-variceal upper gastrointestinal bleeding, it is essential to make an accurate and timely diagnosis and select the most appropriate treatment method. This article introduces the definition of acute non-variceal upper gastrointestinal bleeding (ANVUGIB) and the importance of endoscopic treatment for this disease. It then presents an overview of various assessment systems for ANVUGIB and an overview of endoscopic advances in thermal coagulation, mechanical hemostasis, and topical pharmacological injection hemostasis for three aspects of ANVUGIB-related bleeding. In particular, this article discusses the therapeutic efficacy and safety of different treatment options for non-variceal upper gastrointestinal bleeding, as well as the advantages and limitations of these treatment options in managing this disease....
Background: The role of metabolic dysfunction-associated steatotic liver disease (MASLD) in sleeve gastrectomy (SG)-related outcomes remains uncertain. In this study, we aimed to assess the influence of preoperative biopsy-proven MASLD and its stages on weight loss after SG. Methods: One hundred sixty-three patients with obesity undergoing SG with concomitant intraoperative liver biopsy were followed up for 1 year. Fifty-eight participants were categorized as no MASLD, thirty-eight as metabolic dysfunction-associated steatotic liver (MASL), and sixty-seven as metabolic dysfunction-associated steatohepatitis (MASH). Percentage total weight loss (%TWL) and percentage excess weight loss (%EWL) 1 year after SG were calculated for the different groups. We also evaluated the association between preoperative MASLD (and its stages) and weight loss, after adjusting for potential confounders. Results: Significant differences among groups were detected in %EWL (p = 0.004, ANOVA test), but not in %TWL (p = 0.079). However, significant differences in %TWL were found when MASH and no MASH (i.e., participants with MASL and participants without MASLD) groups were compared (27.3 ± 9.9 vs. 30.7 ± 9, respectively, p = 0.025). In the linear regression model for predicting %EWL 1 year after SG, the presence of MASH was independently associated with a lower %EWL, after adjusting for age, sex, baseline body mass index (BMI), and baseline glycated hemoglobin (HbA1c) (Beta −7.1; 95% CI −13.6, −0.5; p = 0.035). The presence of MASLD, liver fibrosis, or advanced liver fibrosis (≥F2) was also associated with lower %EWL after SG in crude models, although they did not remain significant after adjusting for these confounders. The presence of MASH was inversely related to %TWL, although the association did not remain significant after adjustment (Beta −2.7; 95% CI −5.7, 0.2; p = 0.069). Conclusions: MASH may be independently associated with lower %EWL 1 year after SG in patients with obesity....
