Definitive chemoradiotherapy (CRT) with its significant efficacy and safety in esophageal cancer is reserved for patients with unresectable tumor or those who decline surgery. However, the incidence of locoregional failure or recurrence after definitive CRT remains high. Although esophagectomy is the standard treatment for locoregional failure or recurrence, this approach is associated with high mortality and morbidity. A 56-year-old man diagnosed with esophageal squamous cell carcinoma who refused to undergo surgery received definitive CRT. An endoscopy for response assessment performed after 2 months revealed a residual lesion, which was completely resected by salvage endoscopic submucosal dissection. To the best of our knowledge, endoscopic resection in locoregional failure or recurrence after definitive CRT is very rarely reported, and there are no guidelines or consensus to date. Here, we report a case of successful salvage endoscopic resection of residual lesion after definitive CRT.

Purpose: Expanded indications for endoscopic submucosal dissection (ESD) in early gastric cancer (EGC) remain controversial due to the potential risk of undertreatment after adequate lymph node dissection (LND). Regional LND (RLND) is a novel technique used for limited lymphadenectomy to avoid gastrectomy. This study established the safety and effectiveness of RNLD as an additional treatment option after ESD for expanded indications. Materials and Methods: A total of 69 patients who met the expanded indications for ESD were prospectively enrolled from 2014 to 2017. The tumors were localized using intraoperative esophagogastroduodenoscopy (EGD) before RLND. All patients underwent RLND first, followed by conventional radical gastrectomy with LND. The locations of the preoperative and intraoperative EGD were compared. Pathologic findings of the primary lesion and the RLND status were analyzed. Results: The concordance rates of tumor location between the preoperative and intraoperative EGD were 79.7%, 76.8%, and 63.8% according to the longitudinal, circumferential, and regional locations, respectively. Of the 4 patients (5.7%) with metastatic LNs, 3 were pathologically classified as beyond the expanded indication for ESD and 1 had a single LN metastasis in the regional lymph node. Conclusions: RLND is a safe additional option for the treatment of EGC in patients meeting expanded indications after ESD.

Purpose: Minimal change esophagitis (MCE) is a reflux disease without mucosal breaks, known to be partially associated with abnormal gastric motor function. Electrogastrography (EGG) is commonly applied to assess gastric motor function in a noninvasive fashion. We aimed to determine the relationship between MCE and gastric myoelectrical activity (GME) recorded on EGG in children. Methods: We retrospectively assessed the records of 157 children without underlying disease who underwent both EGG and upper gastrointestinal endoscopy at Gachon University Gil Medical Center between January 2010 and June 2015. The children were stratified according to the appearance of the esophagus (normal vs. MCE). Between-group differences in EGG parameters and their correlation with each MCE finding were statistically analyzed. Results: Only the power ratio, one of the EGG parameters analyzed, differed significantly between the two groups (MCE, $1.68{\pm}3.37$ vs. normal, $0.76{\pm}1.06$; p<0.05), whereas the other parameters, such as dominant frequency, dominant power, and the ratio of abnormal rhythm, showed no differences. Among children with MCE, significant correlations were noted between erythema and power ratio (p<0.05), friability and postprandial dominant frequency (p<0.05), and edema and/or accentuation of mucosal folds and pre-prandial frequency (p<0.05). Helicobacter pylori infection correlated with postprandial arrhythmia (MCE, $33.59{\pm}15.52$ vs. normal, $28.10{\pm}17.23$; p<0.05). EGG parameters did not differ between children with normal esophagus and those with biopsy-proven chronic esophagitis. Conclusion: In children with MCE, gastric dysmotility may affect the development of MCE, manifesting as EGG abnormalities. H. pylori infection may also affect GME. However, larger prospective investigations are needed to confirm these findings.

Background/Aims: Endoscopic submucosal dissection (ESD) has been established as a treatment modality for superficial esophageal squamous cell carcinoma (ESCC). Long-term follow-up data are lacking in Western countries. The aim of this study was to analyze long-term survival in a Western center. Methods: Patients undergoing ESD for ESCC were included. The analysis was performed retrospectively using a prospectively collected database. Results: R0 resection rate was 96.7% (59/61 lesions in 58 patients). Twenty-seven patients (46.6%) fulfilled the curative resection criteria (M1/M2) (group A), 11 patients (19.0%) had M3 lesions without lymphovascular invasion (LVI) (group B), and 20 patients (34.5%) had lesions with submucosal invasion or LVI (group C). Additional treatment was recommended after non-curative resection. It was not performed in 20/31 patients (64.5%), mainly because of comorbidities (75%). Twenty-nine out of 58 (50.0%) patients died during a mean follow-up of 3.7 years. Death was related to ESCC in 17.2% (5/29) of patients. The disease-specific survival rate after curative resection was 100%. Overall survival rates after 5 years were 61.5%, 63.6% and 28.1% for groups A, B, and C, respectively. The overall survival was significantly worse after non-curative resection (p=0.038). Conclusions: Non-curative resection is frequent after ESD for ESCC in Western patients. The long-term prognosis is limited and mainly determined by comorbidity. Early diagnosis and pre-interventional assessments need to be improved.

Background/Aims: This study aimed to determine whether vitamin C in addition to indomethacin decreases the occurrence and severity of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) occurrence and severity. Methods: This randomized clinical trial included patients undergoing ERCP. The participants were administered either rectal indomethacin (100 mg) plus an injection of vitamin C (500 mg) or rectal indomethacin (100 mg) alone just before ERCP. The primary outcomes were PEP occurrence and severity. The secondary amylase and lipase levels were determined after 24 hours. Results: A total of 344 patients completed the study. Based on intention-to-treat analysis, the PEP rates were 9.9% for indomethacin plus vitamin C plus indomethacin and 15.7% for indomethacin alone. Regarding the per-protocol analysis, the PEP rates were 9.7% and 15.7% in the combination and indomethacin arms, respectively. There was a remarkable difference between the two arms in PEP occurrence and severity on intention-to-treat and per-protocol analyses (p=0.034 and p=0.031, respectively). The post-ERCP lipase and amylase concentrations were lower in the combination arm than in the indomethacin alone arm (p=0.034 and p=0.029, respectively). Conclusions: Vitamin C injection in addition to rectal indomethacin reduced PEP occurrence and severity.

Background/Aims: Double-balloon enteroscopy (DBE) allows for the diagnoses and treatment of small bowel tumors (SBTs). This study aimed to evaluate the utility of DBE for the diagnosis and treatment of SBTs. Methods: Patients diagnosed with SBTs who underwent DBE were included in this study. According to their endoscopic appearances, they were categorized as polyps or masses, and according to their histological characteristics, they were categorized as benign or malignant SBTs. Results: A total of 704 patients were retrospectively analyzed, and 90 (12.8%) were diagnosed with SBTs. According to their endoscopic appearance, 48 (53.3%) had polyps and 42 (46.7%) had masses. Additionally, 53 (58.9%) and 37 (41.1%) patients had malignant and benign SBTs, respectively, depending on their histological characteristics. Patients diagnosed with polyps were younger than those diagnosed with masses (p<0.001). Patients diagnosed with benign SBTs were younger than those diagnosed with malignant SBT (p<0.001). Overall, histological diagnosis was determined using DBE in 73 (81.1%) patients. Conclusions: DBE is a useful method for diagnosing SBTs. Additionally, the histological type of the lesion can be determined using DBE.

Background/Aims: Endoscopic ultrasound-guided tissue acquisition (EUS-TA) is essential for the diagnosis of pancreatic cancer. The feasibility of comprehensive genomic profiling (CGP) using samples obtained by EUS-TA has been under recent discussion. This study aimed to evaluate the utility of EUS-TA for CGP in a clinical setting. Methods: CGP was attempted in 178 samples obtained from 151 consecutive patients with pancreatic cancer at the Aichi Cancer Center between October 2019 and September 2021. We evaluated the adequacy of the samples for CGP and determined the factors associated with the adequacy of the samples obtained by EUS-TA retrospectively. Results: The overall adequacy for CGP was 65.2% (116/178), which was significantly different among the four sampling methods (EUS-TA vs. surgical specimen vs. percutaneous biopsy vs. duodenal biopsy, 56.0% [61/109] vs. 80.4% [41/51] vs. 76.5% [13/17] vs. 100.0% [1/1], respectively; p=0.022). In a univariate analysis, needle gauge/type was associated with adequacy (22 G fine-needle aspiration vs. 22 G fine-needle biopsy [FNB] vs. 19 G-FNB, 33.3% (5/15) vs. 53.5% (23/43) vs. 72.5% (29/40); p=0.022). The sample adequacy of 19 G-FNB for CGP was 72.5% (29/40), and there was no significant difference between 19 G-FNB and surgical specimens (p=0.375). Conclusions: To obtain adequate samples for CGP with EUS-TA, 19 G-FNB was shown to be the best in clinical practice. However, 19 G-FNB was not still sufficient, so further efforts are required to improve adequacy for CGP.
