Résumé
Purpose@#The purpose of this study is to determine the effect of group education reflecting unmet needs led by Nurse Practitioners (NPs) on essential knowledge regarding chemotherapy for cancer patients and their families undergoing chemotherapy. @*Methods@#Conducted at a tertiary general hospital in Seoul from December 30, 2020, to April 30, 2022, this study, which is based on a one group pre-post design, involved 104 cancer patients and their families. It assessed differences in knowledge regarding chemotherapy and satisfaction levels by means of participation through video-based group education led by NPs. The data were analyzed with SAS version 9.4 using paired t-tests and multiple logistic regression analysis. @*Results@#The average score of knowledge regarding chemotherapy increased from 80.0 to 89.8 (p<.001). In multivariable logistic regression analysis, being less than 50 years old (adjusted Odds Ratio [aOR]=13.56, 95% Confidence Interval [CI]: 1.76~10.20) and having a college degree or higher (aOR=3.99, 95% CI: 1.15~13.82) were associated with an increase in knowledge regarding chemotherapy. Satisfaction with participation in the group education program was also reported to be high. @*Conclusion@#This study aimed to develop and implement a group education program for cancer patients and their families undergoing chemotherapy, assess changes in knowledge levels, and investigate satisfaction with the program. As a result of the study, the average score of patients who received the group education program increased; thus, it is an effective method for improving the degree of knowledge about the daily life of cancer patients and the management of side effects.
Résumé
Mycoses refer to infectious diseases caused by fungi. Fungal infections are rare and mainly occur as opportunistic infections in immunocompromised patients. Candida species are the most common cause of mycosis; however, members of the order Mucorales or genus Aspergillus may also cause serious fungal infections in immunocompromised hosts. Fungal infections of the gastrointestinal (GI) tract can be asymptomatic or may present with abdominal pain, bloating, diarrhea, or GI bleeding. Although rare, thorough understanding of fungal infections of the upper GI tract encountered in real-world clinical settings can enable early diagnosis and prompt initiation of treatment to improve patient prognosis.

Objectives@#Epidemiological studies have shown an inverse association between Helicobacter pylori infection and ulcerative colitis (UC). In this study, we investigated the protective effects of H. pylori infection on the severity of UC. @*Methods@#This single-center study included 316 patients with newly diagnosed UC based on findings of colonoscopy and upper endoscopy for H. pylori evaluation between January 1994 and December 2015. Patients’ medical records were retrospectively reviewed, and severity of UC was assessed based on endoscopic findings, clinical symptoms, treatment regimens, and Mayo scores. @*Results@#The prevalence of H. pylori infection in patients with UC was 74/316 (23.4%). Based on upper endoscopic findings, the percentage of patients with duodenal ulcers was significantly higher in the H. pylori positive group than that in the H. pylori negative group (27.0% vs. 11.6%, p=0.022). Disease extent and endoscopic severity showed no significant intergroup difference (p=0.765 and p=0.803, respectively). Endoscopic severity was unaffected by the H. pylori infection status, based on the extent of endoscopically documented disease and endoscopic findings. Furthermore, UC-related symptom severity assessed on the basis of stool frequency, rectal bleeding severity, and rate of admission necessitated by UC aggravation was not associated with H. pylori infection (p=0.185, 0.144, and 0.182, respectively). Use of steroids as induction therapy for severe UC did not differ with regard to H. pylori infection (p=0.327). No intergroup difference was observed in disease severity of UC classified using the Mayo score (p=0.323). @*Conclusions@#H. pylori infection was detected in approximately 25.0% of patients with UC. However, the H. pylori infection status was not associated with the severity of UC based on endoscopic disease activity, patients’ symptoms, steroid use, or the Mayo clinic score.
Résumé
Patients frequently report that stress causes or exacerbates gastrointestinal (GI) symptoms, indicating a functional relationship between the brain and the GI tract. The brain and GI tract are closely related embryologically and functionally, interacting in various ways. The concept of the brain–gut axis was originally established in the 19th and early 20th centuries based on physiological observations and experiments conducted in animals and humans. In recent years, with the growing recognition that gut microbiota plays a vital role in human health and disease, this concept has been expanded to the brain–gut–microbiota axis. The brain influences the motility, secretion, and immunity of the GI tract, with consequent effects on the composition and function of the gut microbiota. On the other hand, gut microbiota plays an essential role in the development and function of the brain and enteric nervous system. Although knowledge of the mechanisms through which the gut microbiota influences distant brain function is incomplete, studies have demonstrated communication between these organs through the neuronal, immune, and endocrine systems. The brain–gut–microbiota axis is an essential aspect of the pathophysiology of functional GI disorders such as irritable bowel syndrome, and is also involved in other GI diseases, including inflammatory bowel disease. This review summarizes the evolving concept of the brain–gut–microbiota axis and its implications for GI diseases, providing clinicians with new knowledge to apply in clinical practice.

Background/Aims@#Transcatheter arterial embolization (TAE) is useful for management of uncontrolled upper gastrointestinal (UGI) bleeding. We investigated clinical outcomes of TAE for non-variceal bleeding from benign UGI diseases uncontrolled with endoscopic intervention. @*Methods@#This retrospective study performed between 2017 and 2021 across four South Korean hospitals. Ninety-two patients (72 men, 20 women) who underwent angiography were included after the failure of endoscopic intervention for benign UGI disease- induced acute non-variceal bleeding. We investigated the factors associated with endoscopic hemostasis failure, the technical success rate of TAE, and post-TAE 30-day rebleeding and mortality rates. @*Results@#The stomach (52/92, 56.5%) and duodenum (40/92, 43.5%) were the most common sites of bleeding. Failure of endoscopic procedures was attributable to peptic ulcer disease (81/92, 88.0%), followed by pseudo-aneurysm (5/92, 5.4%), and angiodysplasia (2/92, 2.2%). Massive bleeding that interfered with optimal visualization of the endoscopic field was the most common indication for TAE both in the stomach (22/52, 42.3%) and duodenum (14/40, 35.0%). Targeted TAE, empirical TAE, and exclusive arteriography were performed in 77 (83.7%), nine (9.8%), and six patients (6.5%), respectively. The technical success rate, the post-TAE 30-day rebleeding rate, and the overall mortality rate were 100%, 22.1%, and 5.8%, respectively. On multivariate analysis, coagulopathy (OR, 5.66; 95% CI, 1.71~18.74; P=0.005) and empirical embolization (OR, 5.71; 95% CI, 1.14~28.65; P=0.034) were independent risk factors for post-TAE 30-day rebleeding episodes. @*Conclusions@#TAE may be useful for acute non-variceal UGI bleeding. Targeted embolization and correction of coagulopathy can improve clinical outcomes.
Résumé
Background/Aims@#Esophageal perforation is associated with high mortality and morbidity in patients presenting to the emergency department (ED) with esophageal injury. We investigated the effectiveness of initial CT scan in patients with esophageal injury to determine the risk factors for complications. @*Methods@#Patients admitted through the ED for evaluation of esophageal injuries between January 2001 and May 2020, were investigated. Demographic data, etiological factors, comorbidities, treatment administered, and outcomes were collected. Esophageal injury was graded based on the following CT criteria: (a) normal, (b) pneumomediastinum, (c) mediastinitis, fluid collection, abscess, or overt esophageal wall injury, and (d) pleural effusion, subcutaneous emphysema, or pneumothorax. Grade 2 was defined as microperforation and grades 3 and 4 as overt perforation. @*Results@#Of 281 patients with esophageal injury, 38 had CT-documented overt perforations and 20 had microperforations. Foreign body-induced injury (n=37), Boerhaave syndrome (n=12), and chemical injury (n=3) were common causes of esophageal injury. Complications occurred in 24 (8.5%) patients. Risk factors for complications were age ≥65 years (OR 4.14, 95% CI 1.18~14.56, P=0.027), cerebrovascular disease (OR 8.58, 95% CI 1.13~65.19, P=0.038), Boerhaave syndrome (OR 12.52, 95% CI 2.07~75.68, P=0.006), chemical injury (OR 15.72, 95% CI 3.67~67.28, P<0.001), and CT-documented grade 4 perforation (OR 15.75, 95% CI 4.39~56.55, P<0.001). @*Conclusions@#Initial CT-based grading in the ED are useful for predicting potential complications and for managing patients with esophageal injury and suspected perforation.
Résumé
Purpose@#The impact of the interval between previous endoscopy and diagnosis on the treatment modality or mortality of undifferentiated (UD)-type gastric cancer is unclear. This study aimed to investigate the effect of endoscopic screening interval on the stage, cancerrelated mortality, and treatment methods of UD-type gastric cancer. @*Materials and Methods@#We reviewed the medical records of newly diagnosed patients with UD gastric cancer in 2013, in whom the interval between previous endoscopy and diagnosis could be determined. The patients were classified into different groups according to the period from the previous endoscopy to diagnosis (<12 months, 12–23 months, 24–35 months, ≥36 months, and no history of endoscopy), and the outcomes were compared between the groups. In addition, patients who underwent endoscopic and surgical treatment were reclassified based on the final treatment results. @*Results@#The number of enrolled patients was 440, with males representing 64.1% of the study population; 11.8% of the participants reported that they had undergone endoscopy for the first time in their cancer diagnosis. The percentage of stage I cancer at diagnosis significantly decreased as the interval from the previous endoscopy to diagnosis increased (65.4%, 63.2%, 64.2%, 45.9%, and 35.2% for intervals of <12 months, 12–23 months, 24–35 months, ≥36 months, and no previous endoscopy, respectively, P<0.01). Cancer-related mortality was significantly lower for a 3-year interval of endoscopy (P<0.001). @*Conclusions@#A 3-year interval of endoscopic screening reduces gastric-cancer-related mortality, particularly in cases of UD histology.
Résumé
Idiopathic spontaneous intraperitoneal hemorrhage is both rare and potentially fatal. The incidence of gastroepiploic artery rupture, especially a non-aneurysmal rupture, is extremely low. We report the case of an elderly woman who was mistakenly diagnosed with procedure-related bleeding after gastroscopy. A 0.3 cm polyp was identified and removed during the procedure. The patient later developed shock due to which gastroscopy was repeated; however, no unusual findings were observed. Therefore, abdominopelvic computerized tomography was performed and gastroepiploic artery rupture was detected. Transcatheter arterial embolization was immediately performed without laparotomy, without any complications. The bleeding was controlled, and the patient was discharged after embolization. It is important to acknowledge the possibility of spontaneous rupture of the visceral arteries in elderly individuals with hypertension or atherosclerosis, especially in the event of sudden abdominal pain or shock immediately after an endoscopic procedure. This is the first case report of idiopathic spontaneous rupture of the right gastroepiploic artery successfully managed by transcatheter arterial embolization in South Korea.

Résumé
Early detection of gastric cancer is crucial because the survival rate can be improved through curative treatment. Although surgery and gastrectomy with lymph node dissection remain as the gold standard for curative treatment, early gastric cancer (EGC) with negligible risk of lymph node metastasis can be treated with endoscopic resection (ER), such as endoscopic submucosal dissection. Among gastric cancers, undifferentiated-type cancer is distinguished from differentiated-type cancer in various aspects in terms of clinical features and pathophysiology. The undifferentiated-type cancer is also known to be associated with an aggressive behavior and a poor prognosis. Therefore, the indication of ER for undifferentiated EGC is limited compared with differentiated-type. Recent studies have reported that ER for undifferentiated EGC is safe and shows favorable short- and long-term outcomes. However, it is necessary to understand the details of the research results and to selectively accept them. In this review, we aimed to evaluate the current practice guidelines and the short-term and long-term outcomes of ER for undifferentiated type EGC.
