Possibility of determining high quantitative fecal occult blood on stool surface using hyperspectral imaging.

Background: Fecal immunochemical tests are commonly performed for colorectal cancer screening. Instant fecal occult blood measurement in toilet bowel movements would improve convenience. Hyperspectral imaging (HSI) enables the nondestructive evaluation of materials that are difficult to assess visually.

Assessing the sensitivity and acceptability of the Royal Marsden Palliative Care Referral "Triggers" Tool for outpatients with cancer.

Purpose: To evaluate the use, acceptability, and experience of a seven-item palliative care referral screening tool in an outpatient oncology setting.

Methods: A two-phase convergent parallel mixed-methods study. Patient participants who met any of the "Royal Marsden Triggers Tool" criteria were compared with those who did not in terms of demographic data, palliative care needs (Integrated Palliative Outcome Scale, IPOS) and quality of life indicators (EORTC-QLQ-C30).

Extraction of terminal ileal lipomas to cecum can facilitate endoscopic resection: A case series with video.

Large ileal lipomas over 2 cm can cause symptoms, that may require a resection. Due to the narrow lumen and thin walls of the ileum, endoscopic treatments can have a high risk of adverse events and require technical expertise, thus surgical resection is currently the mainstay of treatment. To overcome the technical challenges, we developed a novel method to endoscopically resect terminal ileal lipomas.

A case of anal canal carcinoma with pagetoid spread that was curatively resected by multiple endoscopic and surgical treatments.

A 57-year-old woman with no significant medical history was referred after a colonoscopy for abdominal distension, which revealed a tumor in the lower rectum. Pre-operative colonoscopy showed the tumor was 12 mm in size, located from the anorectal junction to beyond the dentate line, and was diagnosed as high-grade intramucosal neoplasia or shallow submucosal invasive cancer. Endoscopic submucosal dissection was performed, and the lesion was resected en bloc.

The Management of Direct Oral Anticoagulants for Colorectal Endoscopic Submucosal Dissection: A Multicenter Observational Study.

Background: There is a lack of reports on the use of direct oral anticoagulants (DOACs) during colorectal endoscopic submucosal dissection (ESD).

Aims: We aimed to assess whether the use of DOACs is associated with a higher incidence of delayed bleeding (DB) after ESD.

Methods: A total of 4175 colorectal neoplasms in 3515 patients were dissected at our hospitals during study period.

Endoscopic management of gastric ectopic pancreas with repeated ulcerations and bleeding: A case report.

A 25-year-old man was referred to our center for investigation of a gastric submucosal tumor and an ulcer that had developed on its oral side. Endoscopic ultrasonography findings suggested the presence of an ectopic pancreas, and treatment with an oral proton pump inhibitor was planned for the ulcer. Over the subsequent 3 years, the patient endured recurring epigastric pain and episodes of passing black stools.

A case of small bowel aneurysm hemorrhage with submucosal tumor-like findings.

A 51-year-old woman visited our hospital with the chief complaint of tarry stools. Contrast-enhanced abdominal computed tomography revealed leakage of contrast medium into the lumen of the small intestine. Subsequently, a double-balloon endoscopy was performed, which revealed a submucosal mass-like lesion in the jejunum.

Comparison of cold snare polypectomy for sessile serrated lesions ≥10 mm between experienced and trainee endoscopists: A propensity score matching cohort study.

Objectives: Previous studies of cold snare polypectomy (CSP) for sessile serrated lesions (SSLs) ≥10 mm were performed by experienced endoscopists, and therefore their skills might have significantly influenced results. In this study, we compared the efficacy and safety of CSP for SSLs ≥10 mm between experienced and trainee endoscopists.

Methods: In a 1:1 propensity score matched retrospective cohort study, we compared the complete resection rate, en-bloc resection rate, adverse event rate, and procedure time between experienced and trainee groups.

A case of delayed perforation after cold snare polypectomy treated conservatively by endoscopic clip closure.

We present the case of a 45-year-old man who underwent a screening total colonoscopy and developed delayed perforation after a cold snare polypectomy in the descending colon and sigmoid colon. The patient developed abdominal pain and was referred to our department for further evaluation and treatment. On clinical examination, we noted lower abdominal tenderness, mild rebound pain, and elevated levels of inflammatory markers.

The usefulness of a newly invented transparent silicon attachment: static electricity fastening tape hood.

Video 1Presentation of a newly invented transparent silicon attachment, the static electricity fastening tape hood, and its creation process, durability, and usefulness for various endoscopic procedures.

Efficacy of a novel self-assembling peptide gel for hemostasis in refractory neoplastic bleeding.

Perigastric abscess caused by delayed perforation after gastric endoscopic submucosal dissection: successful conservative treatment without perforation closure: a case report.

Background: Perigastric abscess caused by delayed perforation after endoscopic submucosal dissection is a very rare complication. In principle, delayed perforation after endoscopic submucosal dissection is treated surgically. Herein, we report a case of perigastric abscess caused by delayed perforation after gastric endoscopic submucosal dissection that was treated conservatively, without perforation closure, and in which the patient was discharged from hospital in a short period.

Efficacy and safety of repeated endoscopic radial incision and cutting procedure for benign esophageal stricture.

Radial incision and cutting (RIC) is indicated for refractory benign esophageal strictures after curative treatment for esophageal cancer and has shown favorable short-term outcomes. However, re-stricture after RIC may occur in the long term, and RIC is performed repeatedly in such cases, but the efficacy and safety of repeated RIC are unclear. Therefore, we aimed to demonstrate the efficacy and safety of the repeated RIC for refractory benign esophageal strictures after surgical and non-surgical treatment.
