Abstract

Description: The American College of Physicians (ACP) developed this guideline to provide clinical recommendations on the diagnosis and management of acute left-sided colonic diverticulitis in adults. This guideline is based on current best available evidence about benefits and harms, taken in the context of costs and patient values and preferences. Methods: The ACP Clinical Guidelines Committee (CGC) developed this guideline based on a systematic review on the use of computed tomography (CT) for the diagnosis of acute left-sided colonic diverticulitis and on management via hospitalization, antibiotic use, and interventional percutaneous abscess drainage. The systematic review evaluated outcomes that the CGC rated as critical or important. This guideline was developed using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) methodology. Target Audience and Patient Population: The target audience is all clinicians, and the target patient population is adults with suspected or known acute left-sided colonic diverticulitis.

Funding Information:
The purpose of this American College of Physicians (ACP) guideline is to present recommendations on the use of CT imaging for the diagnosis of acute left-sided colonic diverticulitis and on subsequent management, including hospitalization, antibiotic use, and interventional percutaneous drainage. The Clinical Guidelines Committee (CGC) developed the recommendations, which are based on the best available evidence on benefits and harms, patient values and preferences, and consideration of costs. These recommendations are based on a systematic review conducted by the Brown Evidence-based Practice Center and funded by the Agency for Healthcare Research and Quality (10). The development of the updated accompanying systematic review article was funded by ACP.
