Capsule endoscopy by enabling direct visualization of small bowel mucosa has conquered the last frontier of diagnostic endoscopy. However, its ability to simultaneously detect colonic lesions has not been evaluated. This study was done to evaluate frequency of detection of colonic abnormalities in patients undergoing small bowel capsule endoscopy and its impact on the clinical management.
Eighty-seven patients (60 males; mean age: 51.2 ± 18.6 years) who had obscure gastrointestinal bleeding or unexplained abdominal pain or unexplained diarrhea underwent capsule endoscopy. The demographic data and capsule endoscopy findings were retrospectively evaluated.
Capsule endoscopy was normal in 26 (29.8%) patients and small bowel abnormalities were noted in 49 (56.3%) patients. Capsule endoscope did not reach the cecum during the battery life period of the capsule in five (5.7%) patients. Colonic abnormalities were noted in eight (9.1%) patients. These included cecal angiodysplasia (four), cecal carcinoma (one), transverse colon polyp (one), sigmoid colon ulcerations with histological diagnosis of Crohn's colitis (one), and cecal ulcers with final diagnosis of amebic colitis (one).
The colon should also be carefully evaluated in patients undergoing small bowel capsule endoscopy as significant lesions can be detected that helps in appropriate management.
胶囊内镜通过直接观察小肠黏膜，攻克了诊断内镜的最后一个领域。然而，其同时检测结肠病变的能力尚未得到评估。本研究旨在评估小肠胶囊内镜检查患者结肠异常的检出率及其对临床管理的影响。
87 例（男 60 例；平均年龄：51.2±18.6 岁）有不明原因胃肠道出血或腹痛或腹泻的患者接受了胶囊内镜检查。回顾性评估患者的人口统计学数据和胶囊内镜检查结果。
26 例（29.8%）患者胶囊内镜正常，49 例（56.3%）患者小肠异常。5 例（5.7%）患者因胶囊电池寿命期间胶囊未到达盲肠。8 例（9.1%）患者发现结肠异常。包括盲肠血管瘤（4 例）、盲肠癌（1 例）、横结肠息肉（1 例）、乙状结肠溃疡伴组织学诊断为克罗恩病（1 例）和盲肠溃疡伴最终诊断为阿米巴结肠炎（1 例）。
在进行小肠胶囊内镜检查的患者中，也应仔细评估结肠，因为可能会发现有助于适当管理的显著病变。
