Background: Reports suggest that the rate of adverse events (AEs) post-endoscopic sphincterotomy (ES) to be as high as 10%, with gastrointestinal bleeding being most common after post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis. Objective: The aim of this study was to characterize the incidence of bleeding in patients with thrombocytopenia following ES. Design: Retrospective observational cohort study. Methods: Patients with thrombocytopenia (defined as <150,000 platelets/μL) who underwent ES between May 2017 and December 2020 were identified at a tertiary care medical center. The incidence of immediate (intraprocedural oozing >5 min or requiring intervention) or delayed (clinical bleeding with associated hemoglobin drop within 14 days) post-ES bleeding was determined via manual chart review. Results: A total of 221 patients with a mean platelet count of 108,000 ± 13,000 platelets/μL underwent ERCP with ES. Immediate bleeding occurred in 11 (5%) patients with no significant drop in hemoglobin or transfusion requirement. Two patients (0.9%), both of whom were noted to have immediate bleeding, also developed delayed bleeding. Presence of malignancy was associated with an increased risk of bleeding (36.4% versus 11.4%, p = 0.037) while platelet count was not. Conclusion: In a cohort of patients with thrombocytopenia, rates of immediate and delayed bleeding are similar to previously reported AE rates of ES in the general patient population. Careful attention should be given to patients with a history of active malignancy as well as those who develop immediate bleeding as they appear to be at increased risk for bleeding complications.

Background: The potential therapeutic benefit of intravenous immunoglobulins (IVIGs) for acute attacks of myelin oligodendrocyte glycoprotein antibody disease (MOGAD) is unknown. Objective: The objective was to describe the outcomes of IVIG treatment for acute MOGAD attacks. Methods: A retrospective observational study involving seven tertiary neuroimmunology centers. Data collection included patients’ demographics, Expanded Disability Status Scale (EDSS), and visual acuity (VA) before the attack, at the nadir of the attack before IVIG treatment, and at follow-up visits ⩾3 months after treatment. Results: Thirty-nine patients were included, of which 21 (53.8%) were female. The median age was 23 years (range 5–74 years), and the median disease duration was 4 months (range 0–93 months). The most common type of attack treated with IVIG was isolated optic neuritis (ON) (unilateral n = 14, bilateral n = 5, associated with transverse myelitis (TM), n = 1), followed by acute disseminated encephalomyelitis (ADEM) ( n = 8), multifocal ( n = 7), TM ( n = 3), brainstem ( n = 1), and other encephalitis ( n = 1). A significant improvement in both the EDSS and VA measures was observed at follow-up compared to the time of IVIG treatment initiation ( p < 0.0001 for both outcome measures). Conclusion: IVIG may be an effective treatment option for acute MOGAD attacks. Further prospective studies are warranted to validate our results.

Localized insulinoma is an uncommon entity that can result in substantial morbidity due to the associated hypoglycemia. Recent studies have suggested an increase in the incidence of insulinoma in recent decades that may possibly be secondary to increased awareness, incidental diagnoses, and better diagnostic methods. Diagnosing and localizing insulinoma within the pancreas can be challenging, but advances in nuclear imaging may improve diagnostic accuracy. Delays in diagnosis are common, but once a localized insulinoma is diagnosed and appropriately treated, the long-term prognosis is excellent. Surgical resection is considered the standard of care management option for localized insulinoma, but tumor ablation with endoscopic ultrasound guidance has also been shown to be an effective and safe method for therapy.
