- Gastrointestinal & HepatologyUS2026-07-012021 → 2026Diverticulitis
ACG replaced its 2021 diverticular disease guideline with a document focused on colonic diverticulitis, formalising selective rather than routine antibiotics for low-risk acute uncomplicated disease and listing the high-risk features (immunocompromise, frailty, unsafe outpatient care) that still warrant them. It also recommends against probiotics, mesalamine and rifaximin for recurrence prevention, drops nut/seed/popcorn avoidance, and limits post-recovery colonoscopy to complicated disease or patients with alarm features or overdue screening.

The 2025 AASLD/IDSA guideline tackles six GRADE-based questions the 2018 guidance left unresolved, including whether to treat HBsAg-positive people in the immune-tolerant and indeterminate phases, when to withdraw antiviral therapy, and HCC surveillance in HBV coinfection and after HBsAg loss. Recommendations from 2018 that were not revisited remain in force, and an integrated algorithm combines old and new guidance.
