Invisible perforation during an endoscopic procedure of the esophagus under general anesthesia - A case report -

  • 1Department of Anesthesiology and Pain Medicine, Presbyterian Medical Center, Jeonju, Korea


Endoscopic procedures of the esophagus are more complicated than those of other regions of the gastrointestinal tract. They have a relatively long procedure time and high risk of complications, such as perforation and bleeding. Perforations that occur during the procedure can accompany pneumoperitoneum and pneumomediastinum through leakage of insufflation air and cause severe ventilatory impairment. Case: A 58-year-old male patient underwent enucleation of leiomyoma in the esophagus using endoscopy under general anesthesia. Ventilatory impairment occurred 15 min after commencement of the procedure. Subsequently, subcutaneous emphysema and severe abdominal distension were observed. We suggested the possibility of microperforation during the procedure to the endoscopist, and he performed endoscopic clipping around the excision site of leiomyoma.
Providing anesthetic care by anesthesiologists during endoscopic procedures is considered necessary for patient safety. Complications of endoscopic procedures can be detected and managed early without sequelae during anesthetic care.
