Article Abstract
Background/aim: Endoscopic submucosal dissection (ESD) can be performed to treat laterally spreading duodenal papillary tumors (LSPTs). However, no studies have been conducted on the outcomes of ESDs for LSPTs.
Methods: We retrospectively compared 47 patients who underwent endoscopic papillectomies (EPs) for papillary tumors (PTs) between June 2007 and July 2023 (EP group) and eight patients who underwent ESDs for LSPTs between February 2022 and July 2023 (ESD group). In the subgroup analysis, five patients who underwent EPs for LSPTs were compared with eight patients who underwent ESDs for LSPTs.
Results: Procedure times and tumor diameters were significantly greater in the ESD group than in the EP group. The positive or unclear vertical margin (VM1/X) rate was significantly higher in the ESD group. Additional therapies were administered for patients with VM1/X in the ESD group, and no local recurrence was observed. No delayed adverse events occurred in the ESD group; however, delayed bleeding and perforation occurred in the EP group. In the subgroup analysis, the en bloc resection rate was significantly higher in the ESD group than in the EP group. The VM1/X rate did not differ significantly between groups.
Conclusions: We suggest that ESD is both feasible and safe for LSPTs.

Effectiveness of Self-Assembling Peptide in Reducing Bleeding After Colorectal Endoscopic Submucosal Dissection.

Background And Aims: The newly developed self-assembling peptide (SAP) is expected to exert hemostatic effects on the gastrointestinal tract and promote ulcer healing. However, its efficacy in preventing postprocedural hemorrhage following colorectal endoscopic submucosal dissection (ESD) remains uncertain. This study aimed to determine whether SAP could reduce hematochezia, including delayed bleeding (DB), and prevent its occurrence after colorectal ESD.

Background: Map-like redness (MLR) is a high-risk membrane factor for early gastric cancer (EGC) after the successful eradication of Helicobacter pylori (Hp). This study aimed to analyze the clinical, endoscopic, and pathological characteristics of EGC with surrounding MLR after successful Hp eradication and evaluate the effect of endoscopic submucosal dissection (ESD) resection.
Methods: This retrospective study comprised 23 patients with EGC and surrounding MLR after Hp eradication (MLR group) and 135 patients with EGC without a surrounding MLR (non-MLR; NMLR group).

Background And Aims: Helicobacter pylori (Hp) infection is associated with metachronous gastric cancer (GC) after endoscopic submucosal dissection resection (ESD) in patients with early GC (EGC), but this association has not been well investigated in elderly patients. This study investigated whether Hp infection status was associated with metachronous GC after ESD in patients aged ≥ 75 years.
Methods: This retrospective study involved 298 EGC patients aged ≥ 75 years who underwent ESD.

Background And Aims: Endoscopic submucosal dissection (ESD) enables resection of large (>2cm) colorectal lesions. Despite its proven benefits, ESD remains underutilized in many countries. We evaluated the quality and safety of colorectal ESD resections during the implementation of this technique in a Norwegian endoscopy centre.
