A 64-year-old woman presented with severe abdominal pain and was found to have a large fecolith in the sigmoid colon with resulting bowel obstruction. During a therapeutic colonoscopy, she developed severe shortness of breath and hypoxia, and was found to have a tension pneumothorax. We review the potential mechanisms by which pneumothorax may occur following colonoscopy. In addition, the eight previously published cases are reviewed. Pneumothorax, with or without pneumomediastinum, can occur through a variety of mechanisms following colonoscopy. Although rarely reported, this may represent an underappreciated complication and should be fully investigated in the appropriate setting. Colonoscopy, an exceedingly common procedure, will continue to increase with the aging population. As a result, tension pneumothorax can have a profound effect on the patient outcome and therefore physicians, both gastroenterologists and pulmonologists, should be aware of all the potential problems with this procedure.
一名64岁女性因严重腹痛就诊，检查发现乙状结肠有一个大粪石并导致肠梗阻。在治疗性结肠镜检查期间，她出现严重呼吸急促和低氧血症，被发现患有张力性气胸。我们回顾了结肠镜检查后可能发生气胸的潜在机制。此外，还回顾了之前发表的8例病例。结肠镜检查后，气胸伴或不伴纵隔气肿可通过多种机制发生。虽然报道很少，但这可能是一种未被充分认识的并发症，在适当情况下应进行全面调查。结肠镜检查是一种极其常见的操作，随着人口老龄化将继续增加。因此，张力性气胸会对患者预后产生深远影响，因此胃肠病学家和肺科医生等医生都应了解该操作的所有潜在问题。
