BACKGROUND
Bright red linear marks in the right colon are occasionally seen but have never been described in the medical literature. We have termed this finding "cat scratch" colon.
METHODS
This was a prospective examination of 8277 colonoscopies at a single endoscopy center in a private practice setting. All cases of cat scratch colon were biopsied, and the results read by two pathologists.
RESULTS
A total of 21 cases of cat scratch colon were identified, all in the ascending colon and cecum, with a prevalence of 0.25%. The majority of cases were in women. Although the colon was histologically normal in most cases, there was a significantly higher proportion of collagenous colitis in patients with cat scratch colon compared with the total cohort (14% vs. 0.15%).
CONCLUSIONS
The prevalence of bright red linear markings (cat scratch colon) in the cecum and ascending colon is 0.25%. These markings appear to be superficial breaks in the mucosa possibly secondary to barotrauma. Patients tend to be older women with higher proportion of collagenous colitis.
背景
右半结肠出现的鲜红色线性痕迹偶尔可见，但医学文献中从未有过相关描述。我们将这一发现称为“猫抓痕”结肠。
方法
这是对一家私人诊所环境下单一内镜中心的8277例结肠镜检查进行的前瞻性研究。所有“猫抓痕”结肠病例均进行了活检，结果由两名病理学家解读。
结果
共识别出21例“猫抓痕”结肠病例，均位于升结肠和盲肠，患病率为0.25%。大多数病例为女性。虽然大多数病例的结肠组织学正常，但与整个队列相比，“猫抓痕”结肠患者中胶原性结肠炎的比例显著更高（14%对0.15%）。
结论
盲肠和升结肠中鲜红色线性痕迹（“猫抓痕”结肠）的患病率为0.25%。这些痕迹似乎是黏膜的浅表破损，可能继发于气压伤。患者往往为老年女性，胶原性结肠炎比例较高。
