The purpose of this study was to reassess the findings of Killian-Jamieson diverticula (i.e., proximal lateral cervical diverticula) on pharyngoesophagograms and to compare the prevalence, clinical findings, and radiographic findings of Killian-Jamieson diverticula with those of Zenker's diverticulum.
A computerized search of radiology files revealed 16 patients with Killian-Jamieson diverticula and 26 patients with a Zenker's diverticulum. The double-contrast pharyngoesophagograms and medical records were reviewed retrospectively.
Only three (19%) of 16 patients with Killian-Jamieson diverticula had symptoms attributable to the diverticula (suprasternal dysphagia in two and cough in one), and none had aspiration pneumonia. In contrast, 16 (62%) of 26 patients with a Zenker's diverticulum had suprasternal dysphagia and three patients (12%) had aspiration pneumonia. Twenty Killian-Jamieson diverticula were detected on pharyngoesophagograms in 16 patients, including 12 (75%) with unilateral left-sided diverticula and four (25%) with bilateral diverticula. The Killian-Jamieson diverticula had an average maximal dimension of 1.4 cm. Zenker's diverticulum was nearly four times as common as Killian-Jamieson diverticula and had an average maximal dimension of 2.5 cm. Three patients (11%) with a Zenker's diverticulum had reflux of barium from the diverticula into the hypopharynx with overflow aspiration. Finally, gastroesophageal reflux was detected in nearly twice as many patients with a Zenker's diverticulum as with Killian-Jamieson diverticula.
Killian-Jamieson diverticula are less common and smaller than Zenker's diverticulum. Killian-Jamieson diverticula are less likely to cause symptoms and are less likely to be associated with overflow aspiration or gastroesophageal reflux than is Zenker's diverticulum.
本研究的目的是重新评估咽食管造影中基利安 - 贾米森憩室（即近端外侧颈段憩室）的检查结果，并比较基利安 - 贾米森憩室与Zenker憩室的患病率、临床表现及影像学表现。
通过计算机检索放射学档案，发现16例基利安 - 贾米森憩室患者和26例Zenker憩室患者。对双对比咽食管造影和病历进行回顾性分析。
16例基利安 - 贾米森憩室患者中，仅3例（19%）有与憩室相关的症状（2例有胸骨上窝吞咽困难，1例有咳嗽），且无1例发生吸入性肺炎。相比之下，26例Zenker憩室患者中有16例（62%）有胸骨上窝吞咽困难，3例（12%）发生吸入性肺炎。16例患者的咽食管造影检出20个基利安 - 贾米森憩室，其中12个（75%）为左侧单侧憩室，4个（25%）为双侧憩室。基利安 - 贾米森憩室的平均最大径为1.4 cm。Zenker憩室的发生率几乎是基利安 - 贾米森憩室的4倍，平均最大径为2.5 cm。3例（11%）Zenker憩室患者出现钡剂从憩室反流至下咽并伴有溢流性误吸。最后，检测到Zenker憩室患者发生胃食管反流的人数几乎是基利安 - 贾米森憩室患者的两倍。
基利安 - 贾米森憩室比Zenker憩室少见且更小。与Zenker憩室相比，基利安 - 贾米森憩室引起症状的可能性较小，与溢流性误吸或胃食管反流相关的可能性也较小。
