Characteristics of factors contributing to follow-up for suspect delayed bleeding after colorectal endoscopic submucosal dissection.

BACKGROUND AND AIMS: Delayed bleeding (DB) is a major adverse event associated with colorectal endoscopic submucosal dissection (ESD) that sometimes causes difficulties in making decisions regarding endoscopic hemostasis. This study identified the factors that contribute to follow-up without endoscopic hemostasis when DB is suspected after colorectal ESD. METHODS: In total, 583 patients (603 tumors) who underwent ESD or hybrid ESD for colorectal tumors at Chiba University Hospital between June 2009 and January 2022 were retrospectively registered. Of these, 141 cases (141 tumors) with DB; with hematochezia or hemoglobin decrease ≥2 g/dL after colorectal ESD were analyzed. The DB group was divided into the Hemostasis group (H group; endoscopic hemostasis performed) and no-Hemostasis group (no-H group; no endoscopy performed, or endoscopy performed but no hemostasis performed after hematochezia or hemoglobin decrease). Univariate and multivariate logistic regression analyses were performed to assess the factors contributing to follow-up. RESULTS: Thirty-one patients with 31 tumors were categorized into the H group, while 110 patients with 110 tumors were in the no-H group. Multivariate regression analysis revealed that date from ESD to first hematochezia ≤Day 3 (odds ratio [OR] 4.55, 95% confidence interval [CI] 1.44-14.33; p = 0.010) and bleeding duration ≤1 day (OR 3.35, 95% CI 1.35-8.34; p = 0.009) contributed to follow-up. CONCLUSIONS: In cases of DB after colorectal ESD, a bleeding duration ≤1 day or date from ESD to first hematochezia ≤Day 3 may contribute to follow-up observation without endoscopic hemostasis.

Hepatic encephalopathy due to cardiac cirrhosis.

Right-sided heart failure, including tricuspid regurgitation (TR), can cause cardiac cirrhosis. The pathophysiology is reduced arterial perfusion and passive congestion secondary to increased systemic venous pressure. However, hepatic encephalopathy due to cardiac cirrhosis is rare. This is the first case of hepatic encephalopathy with cardiac cirrhosis caused by persistent TR.

Clinical Features Focusing on Extraintestinal Manifestations in Japanese Patients with Inflammatory Bowel Diseases: Far East 1000.

BACKGROUND: Patients with inflammatory bowel diseases (IBD) can develop extraintestinal manifestations (EIMs) during the disease course, which sometimes impact their quality of life. OBJECTIVES: This study aimed to clarify the prevalence and types of EIMs using a hospital-based IBD cohort in Japan. METHODS: A patient cohort with IBD was established in 2019, as participated by 15 hospitals in Chiba Prefecture of Japan. Using this cohort, the prevalence and types of EIMs, which are defined based on previous reports and the Japanese guidelines, were investigated. RESULTS: This cohort enrolled 728 patients, including 542 ulcerative colitis (UC) and 186 Crohn's disease (CD). Of these patients with IBD, 10.0% were identified with one or more EIMs (57 (10.5%) with UC and 16 (8.6%) with CD). Arthropathy and arthritis were the most common EIM in 23 (4.2%) patients with UC, followed by primary sclerosing cholangitis (PSC) (2.6%). Arthropathy and arthritis were also the most common in patients with CD, but no cases of PSC were observed. EIMs were more frequently observed in patients with IBD treated by specialists than in those treated by non-specialists (12.7% vs. 5.5%, p = 0.011). The incidence of EIMs in patients with IBD was not significantly different over time. CONCLUSIONS: The prevalence and types of EIMs in our hospital-based cohort in Japan did not significantly differ from those reported in previous or Western studies. However, the incidence might be underestimated due to the limited ability of non-IBD specialists to discover and describe EIMs in patients with IBD.

Efficacy of early clip-with-line method for colorectal endoscopic submucosal dissection.

BACKGROUND: Colorectal endoscopic submucosal dissection (ESD) remains demanding due to technical difficulties and high risk of perforation. Most of the reported traction methods are initiated after creating a mucosal flap, which is time consuming. To obtain a good visualization at the mucosal incision stage, we developed the early clip-with-line (ECL) method. This method was started immediately after injection of sodium hyaluronate solution into the submucosal layer. In this study, we evaluated the efficacy and the safety of the ECL method for colorectal ESD. METHODS: We retrospectively analyzed all cases of colorectal ESDs (41 cases in total) performed from January 2017 to February 2019 in our institution. From January 2017 to August 2018, 27 of these cases were performed using conventional (non-ECL) ESDs, while from September 2018 onwards, the remaining 14 cases were performed using the ECL method. Retrospective comparison between the ECL group and the non-ECL group was conducted in terms of clinical characteristics, treatment outcomes, and adverse events. RESULTS: There were no significant differences in clinical characteristics between two groups. Procedure time (median [range]) was significantly shorter in the ECL group than in the non-ECL group (66 [29-131] min vs 90 [30-410] min; P = 0.03). As for adverse events, no case of perforation occurred in the ECL group, whereas perforation was observed in 7.4% (2/27) cases in the non-ECL group (no significant difference). CONCLUSION: Early clip-with-line method for colorectal endoscopic submucosal dissection reduced procedure time.
