Objective Edoxaban is an anticoagulant used for venous thromboembolism (VTE) treatment and requires pretreatment with parenteral anticoagulants. However, pretreatment is not always performed in the clinical setting. In this study, we investigated the safety and effectiveness of edoxaban treatment in patients with VTE with or without pretreatment. ⋯ After propensity score matching, the cumulative incidence of major bleeding was not significantly higher in patients with pretreatment than in those without it (log-rank test, p=0.136). The incidence of deteriorated VTE on imaging did not significantly differ between patients with and without pretreatment, even after propensity matching (log-rank test, p=0.414). Conclusion In a real-world clinical setting, where physicians determined the use of parenteral anticoagulant lead-in according to their experience, patient demographics, and VTE characteristics, no significant differences were found regarding safety and effectiveness in edoxaban-treated VTE patients with or without pretreatment with parenteral anticoagulants.

Rectal prolapse is typically treated surgically, and internal therapy has not been reported. We encountered a case of rectal prolapse that improved with an over-the-scope clip (OTSC) system. ⋯ The OTSC system was used to close the rectal perforation and subsequently improved her rectal prolapse, probably because the rectal wall was anchored to the retroperitoneum. This is the first report to show that rectal prolapse can be endoscopically improved and that an OTSC system might be a viable alternative method for managing inoperable rectal prolapse.

Case Reports
Non-tuberculosis Mycobacterial Pulmonary Disease Caused by Mycobacterium kiyosense, a New Species.
Non-tuberculosis mycobacterial (NTM) pulmonary disease (NTM-PD) is quite common, and newly identified species are being reported increasingly frequently thanks to advances in identification technologies. A 56-year-old woman had mild sputum production showed bronchiectasis with multiple small nodules, consistent with NTM-PD, on chest computed tomography. ⋯ We conducted whole-genome sequencing and identified the NTM isolates as Mycobacterium kiyosense, a species newly registered in 2023 from Japan. She was diagnosed with NTM-PD caused by M. kiyosense and received watchful waiting.

Review Case Reports
Small Bowel Obstruction Caused by Migration of Fractured Metal Stent in Patients with Malignant Gastric Outlet Obstruction: A Report of Two Cases and Review of the Literature.
Gastroduodenal stenting (GDS) is a less invasive alternative to gastrojejunostomy for the management of malignant gastric outlet obstruction (mGOO). GDS is a minimally invasive treatment with good technical and clinical success, and severe complications that require surgical intervention are rare. ⋯ Adverse effects of stent fractures in patients with mGOO have rarely been reported. We herein report two surgical cases of small bowel obstruction caused by the migration of fractured metal stent in patients with mGOO.
