Phytobezoars are a rare cause of small bowel obstruction. Such cases are most commonly associated with previous abdominal surgery or poor dentition or psychiatric conditions. A 40 year old man with a virgin abdomen and excellent dentition and no underlying psychiatric condition presented with an acute abdomen. CT scan revealed a transition point between dilated proximal loops of small bowel and collapsed distal loops. Exploratory laparotomy revealed a phytobezoar unable to be milked into the cecum and an enterectomy with primary anastamosis was performed without complication. A detailed history revealing several less common predisposing factors for phytobezoars should increase clinical suspicion of a phytobezoarinduced small bowel obstruction in the setting of an acute abdomen. Vigilance in presentations of an acute abdomen improves the usefulness of medical imaging, such as a CT, to detect phytobezoars. Understanding mechanisms of phytobezoar formation helps guide management and may prevent surgery.
植物性粪石是小肠梗阻的罕见病因。此类病例最常与既往腹部手术、牙齿不佳或精神疾病相关。一名40岁男性,无腹部手术史,牙齿良好,无潜在精神疾病,出现急腹症。CT扫描显示扩张的近端小肠袢与塌陷的远端小肠袢之间有一个移行点。剖腹探查发现一个无法挤入盲肠的植物性粪石,遂行肠切除术并一期吻合,无并发症发生。详细病史若揭示出植物性粪石的几种较不常见的诱发因素,应提高对急腹症情况下植物性粪石所致小肠梗阻的临床怀疑。对急腹症表现保持警惕可提高医学成像(如CT)检测植物性粪石的效用。了解植物性粪石形成机制有助于指导治疗并可能避免手术。
