The efficacy of vonoprazan-based dual and triple therapy vs. lansoprazole-based triple therapy in the treatment of H. pylori infection was largely consistent regardless of age, sex, race, ethnicity, BMI, alcohol intake, smoking status, and study drug compliance.
Endoscopic submucosal dissection (ESD) has become the treatment of choice for many superficial gastric neoplasms. Clinical outcomes are increasingly comparable between Japanese and Western series; however, data are lacking on the validity of risk stratification tools in Western cohorts. We aimed to evaluate clinical outcomes, explore risk stratification, and compare our data with published Western series.
We conducted a retrospective, observational cohort study in a single tertiary referral center over a 13-year period. Primary outcomes were rates of en bloc, complete (R0) and curative resection. Secondary outcomes included adverse events, recurrence, metachronous lesions, eCura grades, and ESGE criteria. A comparative analysis was performed with existing published series from Western centers.
Totally 112 patients were included in the study cohort. 50.9% were male, 87.5% Caucasian, and median age was 75.5 years (IQR 14.3 years). Lesions were predominantly antral (36.6%) or body (35.7%); median size 20 mm (IQR 15 mm). Rates of en bloc, R0 resection, and curative resection were 96.4%, 89.3%, and 78.6% (identical between eCura and ESGE), respectively. Adverse events occurred in 5.8%, recurrence in 0%, and metachronous lesions in 9.9%. Our data compared favorably with a review existing Western series, which illustrates increasing adoption of ESD and stable outcomes over time.
ESD represents a safe and effective method of treatment for gastric neoplasia in the Western setting. This study highlights the potential for excellent outcomes in a single center with a heterogeneous patient cohort and supports the use of eCura in guiding post procedural management.
Pollen exposure may induce seasonal onset of eosinophilic esophagitis. However, whether serum pollen-specific immunoglobulin E positivity can predict such seasonal eosinophilic esophagitis onset remains unclear. Here, we aimed to evaluate the association between pollen-specific immunoglobulin E positivity and the seasonal onset of eosinophilic esophagitis during the pollen dispersal period.
We seasonally classified eosinophilic esophagitis patients and compared their clinical and endoscopic findings. Seasonal trends with respect to the positivity rate of serum pollen-specific immunoglobulin E were examined. Pollens such as alder, cedar, cypress, birch, orchard grass, timothy, ragweed, and mugwort were evaluated. We classified patients into two groups: tested positive or negative for each pollen-specific immunoglobulin E. We then evaluated whether the positivity of each pollen-specific immunoglobulin E was associated with the seasonal onset of eosinophilic esophagitis during the pollen dispersal period.
We included 122 patients diagnosed with eosinophilic esophagitis between 2010 and 2019. Among them, 31 (25.4%), 42 (34.4%), 29 (23.8%), and 20 (16.4%) patients were diagnosed during spring, summer, fall, and winter, respectively. No significant differences were observed in clinical and endoscopic findings across seasons. No significant seasonal trends were observed in the positivity rate of each pollen-specific immunoglobulin E. The positivity rate of alder-specific immunoglobulin E was significantly associated with the seasonal onset of eosinophilic esophagitis (P < 0.01). However, the positivity rates of other pollen-specific immunoglobulin E were not associated with the seasonal onset of eosinophilic esophagitis.
Serum alder-specific immunoglobulin E positivity was associated with the seasonal onset of eosinophilic esophagitis.
A 73-year-old female with metastatic renal cell carcinoma (RCC) presented with melena and lethargy. She was found to be iron deficient with a hemoglobin of 101 g/L. Her gastroscopy found six irregular pedunculated non-bleeding polyps, 10–20 mm in diameter. Histopathology of the resected polyp returned as metastatic clear cell renal cell carcinoma. Gastric metastases from any primary malignancy are rare and metastatic RCC accounts for only 7% of these tumors. Furthermore, while RCC commonly metastasises to the lung, bone and lymph nodes, metastasis to the gastrointestinal tract is extremely rare, occurring in <1% of patients. Presentation of RCC as a gastric polyp is usually a late event, and on average occurs 6.7 years after initial diagnosis of RCC. Therefore, this case highlights a rare but important late complication of RCC, presenting as gastrointestinal bleeding secondary to gastric metastases.
This study explored the use of transperineal intestinal ultrasound (TPIUS) for assessment of ulcerative colitis (UC) in pregnancy. 8 pregnant women with UC underwent TP-US, clinical assessment and fecal calprotectin. TP-IUS was well tolerated and feasible with adequate rectal views obtained in all trimesters of pregnancy. No correlation between TP-IUS, clinical, or biochemical rectal disease activity assessment was found in this small cohort. Further studies are required to define the optimal technique and references ranges in the pregnant population.
HCV is marked by genetic diversity that impacts disease progression and outcome. Using the NHANES data from 266 HCV-infected adults (2011–2020), this study infers that genotype 1a is the most prevalent (60.2%). Genotype 3 was associated with higher transaminase levels, though not statistically significant. These findings suggest a more aggressive phenotype for genotype 3. Despite pan-genotypic treatment guidelines, this underscores the importance of continued HCV genotype surveillance and consideration for genotype-specific treatment and monitoring strategies.
Chronic constipation negatively impacts work productivity and patients' quality of life. This retrospective study assessed the correlation between symptoms of chronic constipation and work/activity impairment with and without the use of laxative treatment.
This cross-sectional, observational, web-based survey was conducted using the Work Productivity and Activity Impairment-Chronic Constipation Questionnaire and included Japanese patients with chronic constipation receiving prescribed medication. Outcomes of interest included total work productivity and activity impairment and their correlation with constipation symptoms.
Among the 2351 analyzed patients (mean [SD] age, 51.7 [13.8] years), 80.7% were females, 63.3% had a disease duration of ≥10 years, and 1424 were working. The averages of total activity impairment, total work productivity impairment, presenteeism, and absenteeism were 39.2%, 33.9%, 31.2%, and 5.0%, respectively. The annual work productivity loss per patient was estimated to be 1.343 million Japanese Yen. Symptoms that had a statistically significant positive correlation with total work impairment (P < 0.05) were abdominal discomfort/nausea, abdominal pain, abdominal bloating, and unpredictable defecation timing. Total activity impairment was significantly (P < 0.05) affected by abdominal discomfort/nausea, abdominal bloating, abdominal pain, incomplete defecation, unpredictable defecation timing, loss of defecation desire, and straining. Work productivity and daily activity had improved in 71.2% and 72.6% of patients, respectively, after they received treatment.
Symptoms of constipation, particularly abdominal symptoms and unpredictable defecation timing, can have a negative impact on work productivity and daily activity. Treatment focused on these symptoms may reduce the socio-economic burden of chronic constipation in Japan.
A submucosal heterotopic gastric gland (SHGG) is characterized by benign ectopic gastric tissue within the submucosa. Neoplasms arising from SHGGs are rare, and their definitive diagnosis via endoscopic biopsy is often challenging. We report the case of a 74-year-old man undergoing screening esophagogastroduodenoscopy, which revealed a subepithelial lesion with a central orifice in the upper body of the stomach. Endoscopic submucosal dissection (ESD) was performed because the endoscopic biopsy revealed a suspected pyloric gland adenoma. Pathological examination of the resected specimen confirmed SHGG with focal dysplasia. The patient recovered uneventfully and remained free of recurrence over a 5-year follow-up period. This case highlights the utility of ESD in both the treatment and accurate pathological diagnosis of neoplasms arising from SHGGs.
Endoscopic retrograde cholangiopancreatography (ERCP) is the gold standard in managing malignant biliary obstruction. The success of ERCP has limitations, whereas surgical biliary bypass and percutaneous transhepatic approaches, as alternative modalities, come with significant costs, longer durations, and higher levels of mortality and morbidity. Endoscopic ultrasonography (EUS)-guided biliary drainage with two approaches, hepaticogastrostomy (EUS-HGS) and choledochoduodenostomy (EUS-CDS), is a favored and evolving alternative modality. This study aims to compare the efficacy and safety of EUS-HGS and EUS-CDS. We conducted a systematic review and meta-analysis by searching PubMed, ScienceDirect, Cochrane Library, and Scholar databases up to August 2023, based on the 2020 PRISMA guidelines. We identified randomized and nonrandomized studies comparing the efficacy and safety of EUS-HGS and EUS-CDS. Outcome measures included technical and clinical success, side effects, and mean procedure time. Nine nonrandomized studies and two randomized controlled trials involving 537 patients (225 EUS-HGS, 312 EUS-CDS) were analyzed. No difference was found in technical success (OR, 0.83; 95% CI, 0.41–1.68; I2 = 0%) and clinical success between the two procedures (OR, 0.96; 95% CI, 0.51–1.81; I2 = 9.94%). Side effects were significantly higher in EUS-HGS (OR, 2.01, 95% CI, 1.14–3.59; I2 = 0%). No significant difference in mean procedure time was observed between the two procedures (0.13; 95% CI, −0.15–0.41; I2 = 34.89%). There are differences in efficacy and safety between EUS-HGS and EUS-CDS. EUS-CDS has a faster procedure time, lower risk of side effects, and ease of puncture during the procedure.
Inflammatory bowel disease (IBD) is a progressive condition where ongoing inflammation in the gastrointestinal tract can lead to complications such as strictures, and fistulae. The long-term outcomes of newly diagnosed patients under current medical therapy can be used to plan health service provision and guide patients.
Prospective population-based data on all incident patients diagnosed with IBD in Canterbury was gathered in 2014 (n = 205). The medical records of these patients were followed for medication use, disease progression, hospitalization, surgery and mortality, in the 10 years since their diagnosis. Survival analysis and cox regression determined characteristics associated with earlier time to these outcomes.
Medical records of 184 IBD patients were able to be retrieved. Immunomodulators were used by 62% and biologics by 35%; hospitalization occurred for 42% and surgery for 15%. Montreal phenotype progression occurred for 21 and 7% of the cohort died. Younger age at diagnosis hazard ratio (HR) 2.1 (95% confidence interval [CI] 1.1–4.0) and Crohn's disease HR 1.7 (95% CI 1.1–2.6) was associated with immunomodulator use. Younger age was also associated with biologic use HR 2.9 (95% CI 1.2–6.9). Male gender was associated with surgery HR 2.8 (95% CI 1.2–6.4). Perianal disease at diagnosis (14.7%) was associated with immunomodulator use HR 2.58 (95% CI 1.44–4.59) and Montreal phenotype progression HR 2.93 (95% CI 1.10–7.77).
In the 10 years since diagnosis disease progression and treatment escalation occurred for most of this population-based cohort. Earlier intervention for patients with higher-risk characteristics may improve long-term outcomes reducing the burden on health systems.
