中文摘要 | 我們回溯性地研究了8例經開刀証實小腸結石的腹部電腦斷層特徵。其中,最常見且最具特異性的小腸結石電腦斷層特徵是:在小腸腔內有一界線清楚、密度不均勻,並合併有斑駁氣體之腫塊。此特徵有7例。另有1例則是在小腸腔內看到一個均勻鈣化的結石。對於一個急性腸阻塞的病人,在電腦斷層上看到以上之特徵,即可正確診斷小腸結石。 |
英文摘要 | The aim of this study was to determine the computed tomography (CT) appearance of small intestine bezoar (SIB). Eight cases of proven SIB were included in this study. Four of these patients had undergone previous abdominal surgeries, including one patient who had undergone gastric surgery, and one patient who had jejunal diverticular disease. Six patients had bezoars in the ileum and two patients had bezoars in the jejunum. From the CT scans, small bowel obstruction (SBO) was noted in all eight patients. The most common and characteristic CT finding of SIB was a well-circumscribed inhomogenous intraluminal mass with a mottled gas pattern at the site of obstruction. This finding was noted in seven patients. The other patient had a dense compact calcified stone in the small intestine. With the increased use of CT in the evaluation of patients with SBO, it is important to recognize the CT appearance of SIB, as this diagnosis is often not suggested clinically. Identification of a well-circumscribed inhomogenous intraluminal mass with a mottled gas pattern at the site of obstruction is diagnostic of small intestine bezoar. |
