Diagnosis and Management of Acute Left-Sided Colonic Diverticulitis: A Clinical Guideline From the American College of Physicians

Author/s: 
Qaseem, A., Etxeandia-Ikobaltzeta, I., Lin, J. S., Fitterman, N., Shamliyan, T., Wilt, T. J., Clinical Guidelines Committee of the American College of Physicians

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.

Antibiotics After Incision and Drainage for Uncomplicated Skin Abscesses: A Clinical Practice Guide

Author/s: 
Vermandere, Mieke, Aertgeerts, Bert, Agoritsas, Thomas, Liu, Catherine, Burgers, Jako, Merglen, Arnaud, Okwen, Patrick Mbah, Lytvyn, Lyubov, Chua, Shunjie, Vandvik, Per O., Guyatt, Gordon H., Beltran-Arroyave, Claudia, Lavergne, Valéry, Speeckaert, Reinhart, Steen, Finn E., Arteaga, Victoria, Sender, Rachelle, McLeod, Shelley, Sun, Xin, Wang, Wen, Siemieniuk, Reed A.C.

What you need to know

  • For uncomplicated skin abscesses, we suggest using trimethoprim-sulfamethoxazole (TMP-SMX) or clindamycin in addition to incision and drainage rather than incision and drainage alone, and emphasise the need for shared decision making

  • TMP-SMX or clindamycin modestly reduces pain and treatment failure and probably reduces abscess recurrence, but increases the risk of adverse effects including nausea and diarrhoea

  • We suggest TMP-SMX rather than clindamycin because TMP-SMX has a lower risk of diarrhoea

  • Cephalosporins in addition to incision and drainage are probably not more effective than incision and drainage alone in most settings

  • From a societal perspective, the modest benefits from adjuvant antibiotics may not outweigh the harms from increased antimicrobial resistance in the community, although this is speculative
