Objectives

Endoscopic ultrasonography (EUS)-guided radiofrequency ablation has recently been introduced as one of the management strategies for small pancreatic neuroendocrine neoplasms (PNENs). However, prospective data on its safety and efficacy remain limited.

Methods

This prospective pilot study was conducted at Okayama University Hospital from May 2023 to December 2024. Patients with grade 1 PNENs ≤15 mm, confirmed by EUS-guided fine-needle aspiration, were included. The primary endpoint was safety (adverse events [AEs] evaluated according to the 2010 guidelines of the American Society for Gastrointestinal Endoscopy. Severe AEs were defined as moderate or higher in American Society for Gastrointestinal Endoscopy grading and grade ≥3. Secondary endpoints included efficacy (complete response on contrast-enhanced computed tomography at 1 and 6 months), treatment details, device failure, diabetes mellitus exacerbation, and overall survival at 6 months.

Results

Five patients with non-functional PNENs (median age: 64 years; median tumor size: 10 mm) were treated. AEs occurred in two patients (40%, 2/5), although none was severe. Both patients developed asymptomatic pseudocysts, one experienced mild pancreatitis, and both resolved with conservative treatment. The complete response rates on contrast-enhanced computed tomography at one and 6 months were 100%. The median procedure time was 16 min without any device failure, and the median hospitalization was 5 days. None of the patients developed new-onset or worsening diabetes mellitus. The 6-month overall survival rate was 100%.

Conclusion

EUS-guided radiofrequency ablation demonstrated a high complete response rate with no severe AEs in this pilot study, suggesting a minimally invasive option for small, low-grade PNENs (jRCTs062230014).

Severe esophageal strictures resulting from chemoradiotherapy pose persistent therapeutic challenges despite the availability of treatments such as endoscopic balloon dilation and medications. Hyperbaric oxygen therapy (HBOT) has emerged as a promising treatment option for refractory radiation-induced injury to several organs. Herein, we present the case of a 79-year-old male patient with refractory radiation-induced ulcerative esophageal strictures after chemoradiotherapy. Despite multiple interventions, including endoscopic balloon dilation, steroids, and proton-pump inhibitors, the patient remained unable to tolerate oral intake. HBOT was initiated, leading to significant improvement in the esophageal ulcers and strictures within 1 month. HBOT was well tolerated; the patient experienced a sustained improvement in his quality of life. Two years after HBOT, esophagogastroduodenoscopy confirmed persistent improvement in esophageal ulcers and strictures. This case highlights the potential of HBOT as a therapeutic option for ulcerative esophageal strictures unresponsive to conventional treatments.

Objectives

E-learning with video content was created to improve trainees’ biliary cannulation techniques; this study aimed to evaluate its educational effect prospectively.

Methods

E-learning program was conducted using videos demonstrating biliary cannulation for 24 papillae, targeting trainees with 2–6 years of experience in endoscopic retrograde cholangiopancreatography. Ten consecutive cases of biliary cannulation for native papillae performed by trainees were prospectively assessed before and after the e-learning, respectively. The primary outcome was the difficult biliary cannulation rate; the secondary outcomes included a comprehension score assigned by the trainer for each biliary cannulation (maximum of 6 points), trainee failure rate, and adverse events incidence.

Results

Eleven trainees participated in the e-learning program. The overall and per-trainee analyses showed no significant differences in the difficult biliary cannulation rate, trainee failure rate, and adverse event incidence before and after e-learning. However, the overall analysis showed a significant increase in comprehension scores after e-learning (median 4 vs. 5, < 0.01) and the per-trainee analysis revealed that the rate of comprehension score ≥5 increased significantly after e-learning (= 0.02). Comprehension score <5 (odds ratio: 4.31, < 0.01) and endoscopic retrograde cholangiopancreatography experience <3 years (odds ratio: 2.15, p = 0.01) were independent risk factors for difficult biliary cannulation. Additionally, the difficult biliary cannulation incidence showed a negative correlation with the comprehension score (< 0.01).

Conclusions

E-learning using video content did not result in a reduction in the difficult biliary cannulation rate. However, it significantly enhanced procedural understanding, indicating its potential to support future acquisition of biliary cannulation skills.

Objectives

Endoscopic full-thickness resection for gastric submucosal tumors is gradually gaining popularity, and secure and amenable closure is key to its success. This study aimed to compare the reopenable clip over-the-line method with the purse-string method for defect closure after endoscopic full-thickness resection for gastric submucosal tumors.

Methods

This historical control trial included 37 consecutive patients with 37 gastric submucosal tumors, who underwent endoscopic full-thickness resection between January 2021 and July 2024. All lesions were resected en bloc. After excluding three patients who underwent non-full-thickness resection, 34 patients were analyzed. Post-endoscopic full-thickness resection defects were closed using the purse-string method (n = 18) until 2022 and the reopenable clip over-the-line method (n = 16) from 2023.

Results

The median (interquartile range) time for defect closure was longer in the reopenable clip over-the-line method group of 33 (31–57) min than in the purse-string method group of 26 (24–35) min (p = 0.013). The visual analog scale pain score at the umbilical region was lower (p = 0.048) after the reopenable clip over-the-line method than after the purse-string method. In the reopenable clip over-the-line method group, post-procedural abdominal pain was confined to the epigastrium, whereas it extended to the umbilical or left lateral regions in the purse-string method group. The reopenable clip over-the-line method group commenced the diet (p = 0.001) and discharged (p = 0.024) earlier than the purse-string method group.

Conclusions

Reopenable clip over-the-line method facilitated secure post-endoscopic full-thickness resection defect closure, reduced post-procedural abdominal pain, and shortened the fasting and hospitalization periods after endoscopic full-thickness resection in gastric submucosal tumors.

Objectives

We present an update on the (peroral endoscopic myotomy (POEM) difficulty score [PDS] by introducing a novel knife with waterjet functionality.

Methods

This is a retrospective review of patients who underwent POEM between May 2018 and July 2023 at the Kingston Health Sciences Center. Demographic and procedural variables were compared using descriptive and inferential statistics.

Results

One hundred thirty-nine consecutive POEMs were included in the study. Seventy-four (56.7% male; aged 56.7 ± 16.5 years) complex achalasia (CA) and 65 (55.4% female; aged 47.3 ± 20.2 years) non-CA POEM procedures were performed. PDS correlates moderately with procedural efficiency with a correlation coefficient of 0.595 (Spearman's p < 0.001). The mean efficiency for non-CA was 3.3 ± 1.2 min/cm compared to CA as follows: type III 3.3 ± 1.3 min/cm; prior myotomy 5.3 ± 2.3 min/cm; ≧4 prior procedures 4.0 ± 1.7 min/cm; sigmoid type 5.2 ± 2.4 min/cm. The median PDS for non-CA was 1 (1–5). In comparison, the median PDS for CA is as follows: type III 3 (2–4); prior myotomy 4 (3–5); ≧4 prior procedures 3 (1.25–4); sigmoid type 3 (2–4). PDS excluding the presence of spastic contractions correlated better with procedural velocity, with a correlation coefficient of 0.645 (Spearman's p < 0.001).

Conclusions

PDS continues to moderately correlate with procedural efficiency using the novel knife. The presence of spastic contractions correlated poorly with procedural efficiency. Thus, it may be omitted in further studies.

Foreign body ingestion, though rare, poses significant health risks, with 10%–20% of cases requiring endoscopic intervention. This article presents a novel case of a 16-year-old female who ingested a cigarette lighter, leading to abdominal pain and radiographic confirmation of a gastric foreign body. Initial attempts at retrieval using grasping forceps and snares were unsuccessful due to the object's size and shape, risking potential complications. We employed a dual-channel endoscope utilizing a push-pull technique with two snares, one capturing the blunt end and the other the sharp edge of the lighter. This method facilitated safe extraction through the gastroesophageal junction without causing trauma. This case highlights the efficacy of dual snares in the endoscopic retrieval of challenging foreign bodies and emphasizes the importance of appropriate techniques in preventing complications during such procedures.

Objectives

Choledocholithiasis is the leading cause of biliary pancreatitis and biliary sepsis. Endoscopic retrograde cholangiopancreatography (ERCP) is considered a minimally invasive treatment for choledocholithiasis. However, diagnostic ERCP should be avoided. We conducted a prospective trial in high-risk choledocholithiasis patients based on the American Society for Gastrointestinal Endoscopy (ASGE) 2019 criteria to investigate the diagnostic accuracy of the current guideline.

Methods

This multicenter, prospective cohort study included 240 consecutive patients. The primary outcome was the performance of the criteria in predicting choledocholithiasis. The secondary outcome was a percentage reduction in diagnostic ERCP when endoscopic ultrasound was used in tandem with ERCP in individuals without ascending cholangitis.

Results

The overall criteria revealed a positive common bile duct (CBD) stone in 87.1% of patients. Regarding the diagnostic performance of each criterion, ascending cholangitis had a specificity of 67.7% and a positive predictive value (PPV) of 90.2%; total bilirubin >4 mg/dL and dilated CBD had a specificity of 74.2% and a PPV of 55.6%; and CBD stone on ultrasound/cross-sectional imaging had a specificity of 58.1% and a PPV of 89.2%. Of the 138 patients without ascending cholangitis who met the other two high-risk criteria and were sent for EUS first, 21 cases (15.2%) were able to avoid a diagnostic ERCP.

Conclusions

The current ASGE 2019 criteria yield acceptable choledocholithiasis diagnostic accuracy. Using endoscopic ultrasound to confirm CBD stones before ERCP can help almost half of patients with the specific condition of total bilirubin >4 mg/dL and dilated CBD to avoid diagnostic ERCP.

Objectives

Achalasia is an esophageal motility disorder of unknown etiology. However, no studies have determined the populations in which sleep problems occur and whether they are improved by peroral endoscopic myotomy (POEM). We investigated the rate of sleep problems assessed by GERD-Q (AGQ) in achalasia patients, evaluated whether POEM improves these issues, and identified factors associated with sleep improvement after POEM.

Methods

We retrospectively analyzed the data of patients who were diagnosed with achalasia and who underwent POEM at a single institution between March 2016 and December 2020. We examined the Eckardt symptom score and the GERD-Q before and 3 months after POEM to assess the presence of sleep problems (AGQ) and other symptoms. The univariate logistic regression analysis was performed to identify factors associated with sleep problem (AGQ) improvement after POEM.

Results

A total of 177 patients were included. The average age was 52.6 ± 17.2 years. Preoperatively, dysphagia (172 [97.2%]), regurgitation (123 [69.5%]), sleep problems (AGQ; 110 [62.1%]), chest pain (102 [57.6%]), and weight loss (83 [46.9%]) were observed. Before POEM, 62.1% of patients experienced sleep problems (AGQ) compared with 9.6% after POEM (p < 0.0001). Postoperative dysphagia and regurgitation were significant factors determining whether patients continued to experience sleep problems (AGQ) after POEM.

Conclusions

Sleep problems (AGQ) were the third most common symptom in > 60% of patients with achalasia. Improving dysphagia and regurgitation using the POEM procedure improved sleep problems (AGQ).

目的:贲门失弛缓症是一种病因不明的食管运动障碍。然而,没有研究确定发生睡眠问题的人群,以及是否可以通过经口内窥镜肌切开术(POEM)改善睡眠问题。我们调查了用GERD-Q (AGQ)评估的贲门失弛缓症患者的睡眠问题发生率,评估POEM是否改善了这些问题,并确定了POEM后与睡眠改善相关的因素。方法:回顾性分析2016年3月至2020年12月在一家机构诊断为贲门失弛缓症并接受POEM治疗的患者的数据。我们在诗前和诗后3个月检查了Eckardt症状评分和GERD-Q,以评估睡眠问题(AGQ)和其他症状的存在。采用单变量logistic回归分析,确定与POEM术后睡眠问题(AGQ)改善相关的因素。结果:共纳入177例患者。平均年龄52.6±17.2岁。术前,吞咽困难(172例[97.2%]),反流(123例[69.5%]),睡眠问题(AGQ;110例(62.1%)、胸痛102例(57.6%)、体重减轻83例(46.9%)。在POEM治疗前,62.1%的患者有睡眠问题(AGQ),而POEM治疗后为9.6% (p)。结论:睡眠问题(AGQ)是60%贲门失弛缓症患者的第三大常见症状。改善吞咽困难和反流使用POEM程序改善睡眠问题(AGQ)。

Background and aims

Computer-aided detection software (CADe) has shown promising results in real-time polyp detection, but a limited head-to-head comparison of the available CADe systems has been performed. Moreover, such systems have not been compared to endoscopists using standardized videos. This study aims to compare the performance of three CADe systems in detecting polyps, employing a novel standardized methodology.

Methods

Videos from 300 colonoscopies conducted at Oslo University Hospital were analyzed. Short video clips (20–45 s) presenting normal mucosa or polyps were randomly selected. These videos were then streamed through each CADe system from Medtronic, Olympus, and Augere Medical. Each system featured diverse configurations, resulting in a total of six software settings. Sensitivity and false positivity (FP) were assessed by comparing the CADe systems to both the mean of the systems and pairwise between them. Furthermore, the systems’ performance was compared to the performance of five endoscopists.

Results

CADe systems’ sensitivity ranged between 84.9% and 98.7%, with statistically significant differences observed between the systems, both in comparison to the mean and to each other. FP rates ranged between 1.2% and 5.6%, also differing statistically significantly between the systems. The CADe systems achieving the highest sensitivity also exhibited the highest FP. Statistically significant differences in the alert delay were observed between different CADe systems and endoscopists.

Conclusions

This study highlights significant differences between commercially available CADe software regarding sensitivity and FP, but a superior performance compared to endoscopists. The software with the highest sensitivity also exhibited the highest FP, highlighting the need for further refinement.

背景和目的:计算机辅助检测软件(CADe)在实时息肉检测方面显示出有希望的结果,但是对可用的CADe系统进行了有限的头对头比较。此外,这种系统还没有与使用标准化视频的内窥镜医生进行比较。本研究旨在比较三种CADe系统在检测息肉方面的性能,采用一种新的标准化方法。方法:对奥斯陆大学医院300例结肠镜检查录像进行分析。随机选取正常黏膜或息肉的短视频片段(20-45秒)。然后,这些视频通过美敦力、奥林巴斯和奥吉尔医疗的CADe系统进行流式传输。每个系统都有不同的配置,总共有六个软件设置。灵敏度和假阳性(FP)通过将CADe系统与系统的平均值和它们之间的两两比较来评估。此外,将该系统的性能与五名内窥镜医师的性能进行了比较。结果:CADe系统的敏感性在84.9% ~ 98.7%之间,两种系统之间的差异具有统计学意义,无论是与平均值比较还是彼此之间的差异。计划生育率在1.2%到5.6%之间,在不同的系统之间也有统计学上的显著差异。获得最高灵敏度的CADe系统也表现出最高的FP。在不同的CADe系统和内镜医师之间观察到警报延迟的统计学显著差异。结论:本研究强调了市售CADe软件在敏感性和FP方面的显著差异,但与内窥镜医师相比性能优越。具有最高灵敏度的软件也显示出最高的FP,强调需要进一步改进。
