Objectives: Acute hemorrhagic rectal ulcer syndrome (AHRUS) causes massive bleeding and often recurrent rebleeding from rectal ulcers that form immediately above the dentate line. This study aimed to determine the clinical background and risk factors contributing to rebleeding in patients with AHRUS and the most appropriate method of hemostasis treatment.
Methods: This retrospective study included 93 patients diagnosed with AHRUS at Showa University Fujigaoka Hospital, Japan, between April 2009 and November 2018.
Article Synopsis
- - The treatment for inflammatory bowel disease (IBD) with complications like pyoderma gangrenosum (PG) is not well-established, despite common therapies like prednisolone and anti-TNF therapy.
- - A 29-year-old man with ulcerative colitis (UC) and primary sclerosing cholangitis experienced treatment challenges, where initial therapies failed but eventually achieved remission with adalimumab (ADA), which later led to relapse.
- - The case suggests that anti-TNF-α antibodies should be prioritized for refractory UC and PG cases, and switching to different anti-TNFs can help maintain remission if initial treatments are ineffective.
Article Synopsis
- Sessile serrated lesions (SSL) are important precursors to colorectal cancers, and appropriate treatment, like endoscopic submucosal dissection (ESD), could help prevent these cancers.
- In a study involving 370 ESD cases, characteristics of SSL were compared to non-SSL, revealing trends like younger women and proximal colon locations being more common in the SSL group.
- The study found that ESD was safe and had better dissection speeds for SSL compared to non-SSL, suggesting ESD could be a viable treatment option for SSL.
