Ando et al. provide the first direct comparison of endoscopic full-thickness resection (EFTR) and laparoscopic and endoscopic cooperative surgery (LECS) for gastric SMTs in Japan [<span>1</span>]. This comparison should be viewed against different regional paths of development. LECS is established in Japan, whereas extensive experience with exposed EFTR has accumulated in China [<span>2, 3</span>]. Europe and the United States have pursued a more device-driven path, including non-exposed “close-and-resect” EFTR and full-thickness endoscopic suturing systems [<span>2, 4</span>]. These approaches represent different solutions to the same challenge: achieving oncologically sound and mechanically reliable full-thickness resection while remaining minimally invasive.</p><p>After propensity score matching, 21 patients in each group were compared. Macroscopic complete resection was achieved in all patients, and there was no significant difference in the pathological R0 resection rate (91% for EFTR vs. 100% for LECS). EFTR required a substantially shorter procedure time (93 vs. 161 min) and fewer participating physicians (3 vs. 5), together with less blood loss, a shorter post-treatment hospital stay, and lower procedure-related and total hospitalization costs [<span>1</span>]. However, the study should not be interpreted as showing that EFTR is generally superior to LECS. The study included highly selected lesions 3 cm or smaller without ulceration and excluded extraluminal growth-type lesions, and EFTR was performed at expert centers by endoscopists with extensive endoscopic submucosal dissection (ESD) experience. Furthermore, whereas the EFTR group was treated in 2023–2024, the LECS group dated back to 2008, making temporal differences and residual selection bias unavoidable [<span>1</span>]. Costs were evaluated under different Japanese reimbursement schemes, without direct comparison of actual device costs; the reported cost advantage should therefore be interpreted cautiously.</p><p>The first question, therefore, may not be “EFTR or LECS?” but rather “Does this lesion actually need to be resected?” The updated Asian consensus guidelines recommend, in principle, obtaining a histological diagnosis before deciding on treatment, preferably by endoscopic ultrasonography-guided fine-needle aspiration or biopsy (EUS-FNA/FNB), and allow active surveillance for selected gastric GISTs smaller than 2 cm without apparent high-risk features [<span>5</span>]. Tumor characteristics, procedural risk, and patient preference should also be considered [<span>5</span>]. In clinical practice, patient age and comorbidities also influence whether surveillance or intervention is appropriate. Availability of minimally invasive treatment alone should not determine whether a small gastric SMT is resected.

ARMS and ARMA, which were developed as endoscopic procedures for managing gastro-esophageal reflux disease (GERD) since 12 years and pioneered by Inoue H, were compared to the so-called ARMP and ARMP-V [<span>1, 2</span>]. Before starting any commentaries in this Editorial, we have not to forget that ESGE guidelines about Endoscopic management of motility disorders, stated in 2020 “ESGE recommends against the use of Anti Reflux Mucosectomy (ARMS) in routine clinical practice in the treatment of GERD” [<span>3</span>]. However these ESGE guidelines were provided 6 years ago and it could be postulated that any endoscopic treatment for GERD should be analyzed according to the following criteria: Is it a procedure Simple, Efficient, Cost-effective and Safe, namely SECS criteria?</p><p>Yamamoto et al. included 251 patients in a retrospective study with propensity-score matching. These new techniques or improvement changed the concept of mucosectomy previously performed with EMR, ESD or plasma argon to mucoplasty [<span>1</span>]. With ARMP, a mucosal resection on the gastric side of the lesser curve with complete closure with either prong clips or suturing (which was more demanding) was done. The goal was to eliminate the so-called “dead space” below the esogastric junction. A “derivated procedure” was ARM-V where the authors were adding an uvula-like valve after mucosal resection by ESD to anchor a flap.</p><p>We can easily imagine that these improved techniques are clearly more demanding. This is confirmed by an increase of the procedure time from 49.3 mn to 74.6 mn. Moreover, by pooling the ARMS/ARMA results versus ARMP/ARMV results, they found similar postoperative quality of life (QOL) and no significant difference regarding the acid exposure-time (AET 35.1% vs. 45.7%). However, the ARMP/ARMV clearly decreased the rate of adverse events from 25.5% to 5.3%.

Therefore, patients with refractory GERD or PPI dependency with side-effects or contraindications could be candidates for these noninvasive procedures that we could call ARMI for anti-reflux mucosal interventions.

[<span>1</span>] recently reported the development and evaluation of a newly designed endoscope-holding device (scope-holder) intended to reduce the physical burden of flexible endoscopy. Twenty-six participants (17 clinical endoscopists and 9 individuals without a medical background) completed a standardized ex vivo marking task with and without the device in randomized order. In the overall cohort, assistance reduced electromyographic (EMG) activity in the biceps brachii, trapezius, and flexor carpi ulnaris, lowered the National Aeronautics and Space Administration Task Load Index (NASA-TLX), and shortened procedure time. The results are encouraging. What deserves closer attention, however, is not only the magnitude of the effect but also the reasoning that produced the device.</p><p>The clinical problem is well established. A recent systematic review and meta-analysis of 30 studies involving 7646 gastrointestinal endoscopists estimated a pooled career-long prevalence of endoscopy-related injury of 62.5%, albeit with marked heterogeneity [<span>2</span>]. In Japan, a cross-sectional study linked longer monthly exposure to therapeutic procedures, including lower gastrointestinal endoscopic submucosal dissection, with site-specific musculoskeletal symptoms [<span>3</span>]. Ergonomic endoscopy has since been framed as a multilevel discipline [<span>4</span>], and the American Society for Gastrointestinal Endoscopy has issued a dedicated guideline on the prevention of endoscopy-related injury [<span>5</span>]. Behavioral measures such as posture training ask the endoscopist to adapt, whereas workstation optimization and assistive devices seek to reshape the environment or equipment around the operator. For the latter, design choices become consequential.</p><p>Support devices are themselves an established idea. An ergonomically designed endoscope holder evaluated using surface EMG in 15 laparoscopic surgeons reduced activity in several upper-limb and trunk muscles [<span>6</span>], and an endoscope support device tested during simulated colonoscopy reduced load on the left wrist extensors [<span>7</span>]. These devices were designed primarily to reduce physical load, and in such systems, the available range of motion is necessarily shaped by the supporting mechanism. A recurring trade-off is reduced physical load at the cost of maneuverability, a tolerable compromise for relatively static tasks but a potential limitation in therapeutic endoscopy, where repeated scope repositioning is required. Nagano et al. reversed this sequence in what may be described as a kinematics-informed design, in which the device's permitted motion is derived from measured endoscopist movement rather than assumed. They first quantified how clinical endoscopists actually move, tracking left-hand trajectories during 25 upper gastrointestinal procedures, then defined the device's movement envelope as the observed mean ±2 SD along three axes and engineered ","PeriodicalId":159,"journal":{"name":"Digestive Endoscopy","volume":"38 9","pages":""},"PeriodicalIF":3.6,"publicationDate":"2026-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/den.70293","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149018852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This produces the characteristic two-toned appearance on histology, with intraepithelial splitting, parakeratosis and often minimal inflammation, and strips or sheets of sloughed mucosa at endoscopy. On rare occasions patients cough up or vomit tubular mucosal casts.

Most series describe older adults, with reported median ages in the sixth to eighth decade and a female predominance in the majority of cohorts.

This strategy is supported by substantial evidence showing that established pathological risk factors identify patients at increased oncological risk and that additional surgery is associated with improved long-term outcomes, including disease-specific survival (DSS) and overall survival (OS), in appropriately selected patients [<span>2</span>]. A recent meta-analysis by Chen et al. demonstrated that surgical resection was associated with improved DSS compared to local resection, although this benefit became more apparent only after prolonged follow-up [<span>3</span>]. The 5-year DSS rates were similar between the two groups (96.7% vs. 98.3%), whereas a more substantial difference emerged after 10 years (86.9% vs. 97.1%). In contrast, the corresponding differences in OS remained relatively modest (86.3% vs. 94.5% at 5 years and 72.9% vs. 84.4% at 10 years), reflecting the influence of competing mortality. These findings suggest that the oncological benefits of surgery accumulate gradually over time and may not be fully realized in older adults with limited life expectancy and a high risk of competing mortality. In a real-world setting, among patients aged ≥ 80 years with high-risk pT1 colorectal cancer, there was no significant difference in OS between patients managed with endoscopic resection alone and those who underwent additional surgery when treatment was selected based on the patients' overall condition and surgical tolerability [<span>4</span>].
