To evaluate how the use of ultrasonography (US) and computed tomography (CT) has changed insights on the frequency and natural history of right colonic diverticulitis.
Clinical findings, US and CT images, and clinical and surgical records in 44 patients with a final diagnosis of right colonic diverticulitis seen over 11 years were retrospectively studied.
Of the 44 patients, three underwent diverticulectomy, and 41 were successfully treated conservatively. Follow-up US demonstrated a consistent change in the pattern of the findings of diverticulitis over time, with eventual spontaneous evacuation of the contents of the inflamed diverticulum into the colonic lumen. Five patients had recurrent symptoms; two of them underwent elective surgery. The frequency of right colonic diverticulitis was one in 34 appendectomies, which is nine times higher than that reported to date.
Right colonic diverticulitis is more common than has been previously reported. US and CT findings are characteristic and show a consistent pattern of changes over time. The natural history is benign, and surgical intervention can be avoided in the vast majority of patients.
评估超声检查（US）和计算机断层扫描（CT）的应用如何改变了对右半结肠憩室炎发生率及自然病程的认识。
回顾性研究了11年间最终诊断为右半结肠憩室炎的44例患者的临床资料、US和CT图像以及临床和手术记录。
44例患者中，3例行憩室切除术，41例经保守治疗成功。随访US显示憩室炎表现随时间有持续变化，最终炎症性憩室内的内容物自发排入结肠腔。5例患者有复发症状；其中2例行择期手术。右半结肠憩室炎在34例阑尾切除术中出现1例，比迄今报道的发生率高9倍。
右半结肠憩室炎比先前报道的更为常见。US和CT表现具有特征性，且随时间呈现持续的变化模式。其自然病程是良性的，绝大多数患者可避免手术干预。
