Graphical Abstract Abstract PDF PubReader ePub: Background
/Aims: Visualization of palisade vessels (PVs) in Barrett’s esophagus is crucial for proper assessment. This study aimed to determine whether red dichromatic imaging (RDI) improves PV visibility compared with white-light imaging (WLI) and narrow-band imaging (NBI).
Methods
Five expert and trainee endoscopists evaluated the PV visibility in Barrett’s esophagus using WLI, NBI, and RDI on 66 images from 22 patients. Visibility was rated on a 4-point scale: 4, excellent; 3, good; 2, fair; and 1, poor. The color difference between the most recognizable PV spots and surrounding areas with undetectable blood vessels was also analyzed.
Results
Mean visibility scores were 2.6±0.7, 2.3±0.6, and 3.4±0.4 for WLI, NBI, and RDI, respectively. The RDI scores were significantly higher than the WLI (p<0.001) and NBI (p<0.001) scores. These differences were recognized by trainees and expert endoscopists. Color differences in PVs were 7.74±4.96 (WLI), 10.43±5.09 (NBI), and 15.1±6.54 (RDI). The difference in RDI was significantly higher than that in WLI (p<0.001) and NBI (p=0.006).
Conclusions
RDI significantly improved PV visibility compared to WLI and NBI based on objective and subjective measures.

Management of esophageal neoplasms by endoscopic submucosal dissection: experience over 100 consecutive procedures: Josué Aliaga Ramos, Yoshinori Morita, Takashi Toyonaga, Danilo Carvalho, Moises Salgado Pedrosa, Vitor N. Arantes; Clin Endosc 2023;56(5):613-622. Published online May 17, 2023; DOI: https://doi.org/10.5946/ce.2022.245

Graphical Abstract Abstract PDF PubReader ePub: Background
/Aims: Endoscopic submucosal dissection (ESD) is currently considered the first-line treatment for the eradication of superficial neoplasms of the esophagus in Eastern countries. However, in the West, particularly in Latin America, the experience with esophageal ESD is still limited because of the high technical complexity required for its execution. This study aimed to present the results of the clinical application of ESD to manage superficial esophageal neoplasms in a Latin American center in over 100 consecutive cases.
Methods
This retrospective study included consecutive patients who underwent endoscopic ESD for superficial esophageal neoplasms between 2009 and 2022. The following clinical outcomes were assessed: en bloc, complete, and curative resection rates, local recurrence, adverse events, and procedure-related mortality.
Results
Esophageal ESD was performed mainly for squamous cell carcinoma (66.6%), high-grade intraepithelial neoplasia (17.1%), and adenocarcinoma (11.4%). En bloc and complete resection rates were 96.2% and 81.0%, respectively. The curative resection rate was 64.8%. Adverse events occurred in six cases (5.7%). Endoscopic follow-up was performed for an average period of 29.7 months.
Conclusions
ESD performed by trained operators is feasible, safe, and clinically effective for managing superficial neoplastic lesions of the esophagus in Latin America.

Background
/Aims: Endoscopic submucosal dissection (ESD) for diverticulum-associated colorectal lesions is generally contraindicated because of the high risk of perforation. Several studies on patients with such lesions treated with ESD have been reported recently. However, the feasibility and safety of ESD for lesions in proximity to a colonic diverticulum (D-ESD) have not been fully clarified. The aim of this study was to evaluate the feasibility and safety of D-ESD.
Methods
D-ESD was defined as ESD for lesions within approximately 3 mm of a diverticulum. Twenty-six consecutive patients who underwent D-ESD were included. Two strategic approaches were used depending on whether submucosal dissection of the diverticulum-related part was required (strategy B) or not (strategy A). Treatment outcomes and adverse events associated with each strategy were analyzed.
Results
The en bloc resection rate was 96.2%. The rates of R0 and curative resection in strategies A and B were 80.8%, 73.1%, 84.6%, and 70.6%, respectively. Two cases of intraoperative perforation and one case of delayed perforation occurred. The delayed perforation case required emergency surgery, but the other cases were managed conservatively.
Conclusions
D-ESD may be a feasible treatment option. However, it should be performed in a high-volume center by expert hands because it requires highly skilled endoscopic techniques.

Clinical Impact of Different Reconstruction Methods on Remnant Gastric Cancer at the Anastomotic Site after Distal Gastrectomy: Kei Matsumoto, Shinwa Tanaka, Takashi Toyonaga, Nobuaki Ikezawa, Mari Nishio, Masanao Uraoka, Tomoatsu Yoshihara, Hiroya Sakaguchi, Hirofumi Abe, Tetsuya Yoshizaki, Madoka Takao, Toshitatsu Takao, Yoshinori Morita, Hiroshi Yokozaki, Yuzo Kodama; Clin Endosc 2022;55(1):86-94. Published online August 13, 2021; DOI: https://doi.org/10.5946/ce.2021.084

Abstract PDF Supplementary Material PubReader ePub: Background
/Aims: The anastomotic site after distal gastrectomy is the area most affected by duodenogastric reflux. Different reconstruction methods may affect the lesion characteristics and treatment outcomes of remnant gastric cancers at the anastomotic site. We retrospectively investigated the clinicopathologic and endoscopic submucosal dissection outcomes of remnant gastric cancers at the anastomotic site.
Methods
We recruited 34 consecutive patients who underwent endoscopic submucosal dissection for remnant gastric cancer at the anastomotic site after distal gastrectomy. Clinicopathology and treatment outcomes were compared between the Billroth II and non-Billroth II groups.
Results
The tumor size in the Billroth II group was significantly larger than that in the non-Billroth II group (22 vs. 19 mm; p=0.048). More severe gastritis was detected endoscopically in the Billroth II group (2 vs. 1.33; p=0.0075). Moreover, operation time was longer (238 vs. 121 min; p=0.004) and the frequency of bleeding episodes was higher (7.5 vs. 3.1; p=0.014) in the Billroth II group.
Conclusions
Compared to remnant gastric cancers in non-Billroth II patients, those in the Billroth II group had larger lesions with a background of severe remnant gastritis. Endoscopic submucosal dissection for remnant gastric cancers in Billroth II patients involved longer operative times and more frequent bleeding episodes than that in patients without Billroth II.

Efficacy of the Envelope Method in Applying Polyglycolic Acid Sheets to Post-Endoscopic Submucosal Dissection Ulcers in Living Pigs: Hiroya Sakaguchi, Toshitatsu Takao, Yoshitaka Takegawa, Yuki Koga, Kazunori Yamanaka, Masataka Sagata, Shinwa Tanaka, Yoshinori Morita, Takashi Toyonaga, Yuzo Kodama; Clin Endosc 2021;54(1):64-72. Published online July 16, 2020; DOI: https://doi.org/10.5946/ce.2020.014

Abstract PDF Supplementary Material PubReader ePub

Background
/Aims: Application of polyglycolic acid (PGA) sheets using fibrin glue in post-endoscopic submucosal dissection (ESD) ulcers to prevent bleeding has been reported to be difficult with the conventional delivery method because of gravity. This study assessed the usefulness of the envelope-based delivery system with and against gravity in living pigs.
Methods
PGA sheets were applied on post-ESD ulcers with and against gravity six times each using the conventional and envelope methods, respectively. The PGA sheet delivery time and the endoscopic and histological findings of the treated ulcer floors were compared.
Results
With gravity, the median PGA sheet application time was 1.00 (0.68–1.30) min/cm² and 0.32 (0.18–0.52) min/cm² with the conventional and envelope techniques (p=0.002), respectively, and against gravity, it was 1.20 (1.13–1.63) min/cm² and 0.50 (0.39–0.58) min/cm² (p=0.002), respectively. Against gravity, the endoscopic and histological findings revealed that the conventional group had insufficient fixation of the PGA sheets, but the envelope groups had sufficient fixation. The results with gravity were similar between the groups.
Conclusions
The envelope method makes it possible to deliver PGA sheets to the stomach quickly and cover ulcers appropriately both with and against gravity in living pigs.

Abstract PDF PubReader ePub

Background
/Aims: Mucosal cutting biopsy (MCB) is useful for the histopathological diagnosis of gastric subepithelial tumors (SETs). However, there is little information on cases in which MCB did not establish a diagnosis. In the current study, we aimed to investigate the characteristics of cases in which MCB was unsuccessful.
Methods
Cases in which MCB was used to histopathologically diagnose gastric SETs at Kobe University Hospital between August 2012 and October 2018 were retrospectively reviewed.
Results
Forty-five cases in which MCB was used to diagnose 43 gastric SETs in 43 patients were analyzed. The median tumor size was 20 mm (range, 8–50 mm). Pathological examinations resulted in definitive and suspected diagnoses and no diagnosis in 29 (gastrointestinal stromal tumor: n=17, leiomyoma: n=7, aberrant pancreas: n=3, others: n=2), 6, and 10 cases, respectively. Failure to expose the tumor according to retrospective examinations of endoscopic images was significantly associated with no diagnosis. Other possible explanations included a less elevated tumor, biopsy of the surrounding field instead of the tumor due to the mobility, and poor endoscope maneuverability due to the tumor being close to the cardia.
Conclusions
Clear exposure of gastric SETs during MCB may improve the diagnostic rate of such examinations.

Focused Review Series: Globalization and Universalization of ESD

Principles of Quality Controlled Endoscopic Submucosal Dissection with Appropriate Dissection Level and High Quality Resected Specimen: Takashi Toyonaga, Eisei Nishino, Mariko Man-i, James E. East, Takeshi Azuma; Clin Endosc 2012;45(4):362-374. Published online November 30, 2012; DOI: https://doi.org/10.5946/ce.2012.45.4.362

Abstract PDF PubReader ePub

Endoscopic submucosal dissection (ESD) has enabled en bloc resection of early stage gastrointestinal tumors with negligible risk of lymph node metastasis, regardless of tumor size, location, and shape. However, ESD is a relatively difficult technique compared with conventional endoscopic mucosal resection, requiring a longer procedure time and potentially causing more complications. For safe and reproducible procedure of ESD, the appropriate dissection of the ramified vascular network in the level of middle submucosal layer is required to reach the avascular stratum just above the muscle layer. The horizontal approach to maintain the appropriate depth for dissection beneath the vascular network enables treatment of difficult cases with large vessels and severe fibrosis. The most important aspect of ESD is the precise evaluation of curability. This approach can also secure the quality of the resected specimen with enough depth of the submucosal layer.
