18. Efficacy of Step‐Down Therapy Using Vonoprazan for Symptomatic Mild Reflux Esophagitis.

Author

Ochiai, Yorinari, Kikuchi, Daisuke, Hoteya, Shu, and Ricci, Chiara

Abstract

Objective: Patient‐reported outcomes (PROs) are becoming pivotal in managing gastroesophageal reflux disease (GERD). Current Japanese guidelines for GERD recommend vonoprazan (VPZ) as a treatment option for mild reflux esophagitis (RE). However, it has been hypothesized that 4 weeks of VPZ 20 mg is not always necessary for mild RE if the treatment outcome is based on patient symptoms. This study is aimed at elucidating the efficacy of a new tapering therapeutic strategy (step‐down therapy) using VPZ for symptomatic mild RE based on PRO. Methods: This multicenter retrospective study examined VPZ's efficacy for step‐down therapy between October 2021 and November 2022. Included were 63 consecutive patients from the outpatient clinics of Toranomon Hospital and Toranomon Hospital Kajigaya with symptoms associated with RE (frequency scale for the symptoms of GERD (FSSG) scores ≥ 8 points) and mild RE classified as the Los Angeles Classification Grade A or B. Step‐down therapy was defined as a treatment period of 28 days. VPZ 20 mg was administered as the initial treatment. Afterward, patients were allowed to step down to VPZ 10 mg if their symptoms improved, and VPZ could be discontinued if symptoms disappeared. If symptoms worsened, the dosage could be increased from 10 to 20 mg VPZ, or VPZ could be restarted at 20 mg after discontinuation. Results: The proportion of patients whose FSSG scores decreased by ≥ 3 points with step‐down therapy was 76.2% (48/63 patients). The median FSSG scores before and after step‐down therapy were 13 (range, 8–35) and 7 (range, 0–29), respectively (p < 0.01). Overall, 71.4% (45/63) of the patients stepped down from 20 to 10 mg VPZ, and 46% (29/63) of the patients discontinued VPZ. Conclusion: Step‐down therapy using VPZ may be a viable treatment option for symptomatic patients with mild RE. [ABSTRACT FROM AUTHOR]

Abstract

Aim: We conducted a multicenter study on classical laparoscopic and endoscopic cooperative surgery (LECS) and LECS‐related procedures to retrospectively clarify the safety, problems, and mid‐term outcomes of these methods after their coverage by the national health insurance. Methods: A total of 201 patients who underwent classical LECS/LECS‐related procedures for gastric submucosal tumors (G‐SMTs) in 21 institutions affiliated with the Laparoscopy Endoscopy Cooperative Surgery Study Group from April 2014 to March 2016 were included. Data was retrospectively obtained from the patients' charts. Results: The most common surgical procedure was classical LECS (155 patients, 77.1%), non‐exposed endoscopic wall inversion surgery (22 patients, 11.4%), a combination of laparoscopic and endoscopic approaches to neoplasia with non‐exposure technique (16 patients, 8%), and closed LECS (two patients, 1%). Only six (3%) patients underwent LECS with gastrostomy. The mean operative time and blood loss were 188.4 (70–462) minutes and 23.3 (0–793) g, respectively. Ten (5%) patients developed postoperative complications (Clavien–Dindo classification grade II or higher). Two patients needed reoperation due to postoperative bleeding or anastomotic leakage. All tumors were resected with negative margins. A total of 127 (63.2%) patients underwent follow‐up observations for over 36 months, one of whom had a recurrence of peritoneal dissemination and one had poor oral intake. Conclusion: Classical LECS and LECS‐related procedures for G‐SMTs have favorable short/mid‐term outcomes. We conducted a multicenter study on classical laparoscopic and endoscopic cooperative surgery (LECS) and LECS‐related procedures to retrospectively clarify the safety, problems, and mid‐term outcomes of these methods after their coverage by the national health insurance.

Subjects
*GASTROESOPHAGEAL reflux, *PARIETAL cells, *LOGISTIC regression analysis, *ANTACIDS, *UNIVARIATE analysis
Abstract

Background and Aim: Since the first report of gastric adenocarcinoma of the fundic‐gland type in 2010, the clinicopathological characteristics of gastric neoplasm of the fundic‐gland type (GNFG) have become clearer; however, their risk factors remain unclear. This exploratory study aimed to identify the risk factors for GNFG. Methods: We conducted a single‐center, retrospective, matched case–control study using medical information recorded at our health management center from January 2014 to July 2023. During this period, 39 240 people underwent upper gastrointestinal endoscopy. GNFG were extracted as cases and matched to controls, according to age and sex, in a 1:8 ratio, excluding those with a history of gastrointestinal surgery and those with a history or comorbidity of cancer. Univariate analysis was used to compare patient background and endoscopic findings. Multivariable analysis was performed, adjusting for factors with P values < 0.1 and antacid use. Results: A total of 20 GNFG cases and 160 matched healthy controls were included. In the univariate analysis, only reflux esophagitis was significantly more common in GNFG (40.0% vs 18.1%; P = 0.036). Factors antacids and duodenitis had P values < 0.1. Logistic regression analysis was performed, adjusting for antacids, reflux esophagitis, and duodenitis. Antacids and reflux esophagitis were the independent risk factors for GNFG (odds ratio = 3.68 [95% confidence interval: 1.04–11.91] and 3.25 [95% confidence interval: 1.11–9.35]). Conclusions: Although the sample of patients with GNFG was small, antacids and reflux esophagitis were identified as a risk factor. The pathogenesis of antacids and reflux esophagitis may be involved in the development of GNFG. [ABSTRACT FROM AUTHOR]

Subjects

Abstract

Introduction: We investigated the factors associated with synchronous multiple early gastric cancers and determined their localization. Methods: We analyzed 8,191 patients who underwent endoscopic submucosal dissection for early gastric cancers at 33 hospitals in Japan from November 2013 to October 2016. Background factors were compared between single-lesion (n = 7,221) and synchronous multi-lesion cases (n = 970) using univariate and multivariate analyses. We extracted cases with two synchronous lesions (n = 832) and evaluated their localization. Results: Significant independent risk factors for synchronous multiple early gastric cancer were older age (≥75 years old) (odds ratio [OR] = 1.257), male sex (OR = 1.385), severe mucosal atrophy (OR = 1.400), tumor localization in the middle (OR = 1.362) or lower region (OR = 1.404), and submucosal invasion (OR = 1.528 [SM1], 1.488 [SM2]). Depressed macroscopic type (OR = 0.679) and pure undifferentiated histology OR = 0.334) were more common in single early gastric cancers. When one lesion was in the upper region, the other was more frequently located in the lesser curvature of the middle region. When one lesion was in the middle region, the other was more frequently located in the middle region or the lesser curvature of the lower region. When one lesion was in the lower region, the other was more frequently located in the lesser curvature of the middle region or the lower region. Conclusion: Factors associated with synchronous multiple early gastric cancer included older age, male sex, severe mucosal atrophy, tumor localization in the middle or lower region, and tumor submucosal invasion. Our findings provide useful information regarding specific areas that should be examined carefully when one lesion is detected. [ABSTRACT FROM AUTHOR]

Abstract

Background and Aim: Perforation is one of the most important complications of endoscopic submucosal dissection (ESD) for early gastric cancer (EGC). Several studies have examined risk factors for intraoperative and delayed perforations, but most were retrospective analyses with small numbers of patients. Methods: This study represents a secondary analysis of a Japanese multicenter prospective cohort study. We investigated the factors associated with each type of perforation using 9015 patients with 9975 EGCs undergoing ESD between July 2010 and June 2012. Results: Intraoperative perforation occurred in 198 patients (2.2%) with 203 lesions (2.0%), necessitating emergency surgery for four lesions (0.04% [2.0%, 4/203]). Delayed perforation occurred in another 37 patients (0.4%) with 42 lesions (0.4%), requiring emergency surgery for 12 lesions (0.12% [28.6%, 12/42]). Factors showing significant independent correlations with intraoperative perforation were upper or middle third of the stomach; remnant stomach or gastric tube; procedure time ≥100 min; tumor size >35 mm; body mass index (BMI) < 18.5 kg/m2; and ≥72 years. Factors showing significant independent correlations with delayed perforation were procedure time ≥60 min; BMI < 18.5 kg/m2; ≥75 years; ulceration; and tumor size >20 mm. Intraoperative perforation occurred most frequently at the greater curvature in the upper third of the stomach (7.9%), whereas delayed perforation occurred most frequently at the greater curvature in the middle third (1.2%). Conclusion: This multicenter prospective cohort study clarified the risk and risk factors of intraoperative and delayed perforation related to ESD for EGCs, providing information to help endoscopists reduce perforation.
