A phytobezoar is the most common type of bezoar, which is a gastrointestinal mass composed of vegetable. A persimmon is a common cause of a phytobezoar. The majority of bezoars are found in the stomach, with the small intestine being the next most commonly involved site. The colon is a rare site for a bezoar. Recently, we experienced a colonic bezoar that caused colonic obstruction in a 66-year-old female patient who took persimmons regularly. The patient came to the hospital because of abdominal pain and distension. To differentiate a tumor or other problems that can cause intestinal obstruction, we performed an abdominal computed tomography scan and found an ovoid intraluminal mass with a mottled gas pattern in the distal descending colon. A large impacted bezoar was seen in the sigmoid colon, which was completely obstructed, and it was successfully removed by using colonoscopy.
植物性胃石是最常见的胃石类型，它是由植物构成的胃肠道团块。柿子是植物性胃石的常见成因。大多数胃石见于胃内，其次最常累及的部位是小肠。结肠是胃石的罕见发病部位。最近，我们诊治了一名66岁的女性患者，她经常食用柿子，发生了导致结肠梗阻的结肠胃石。患者因腹痛和腹胀前来就诊。为鉴别可导致肠梗阻的肿瘤或其他问题，我们进行了腹部计算机断层扫描，发现降结肠远端有一个椭圆形腔内肿块，伴有斑驳的气体影。在乙状结肠可见一个巨大嵌顿性胃石，肠腔完全梗阻，通过结肠镜检查成功将其取出。
