Carbon dioxide embolism during transanal total mesorectal excision (taTME)
- 56 Downloads
Transanal total mesorectal excision (taTME) is a relatively new surgical approach that has become increasingly common for patients with low rectal cancer. This approach uses subperitoneal carbon dioxide (CO2) to create the pelvic workspace and perform the operation from the anal side. Thereby, a good surgical performance is achieved for a narrow pelvis, which is difficult with laparoscopy from the abdominal side. However, taTME is associated with potentially life-threatening complications, including CO2 embolism , which is not a commonly encountered complication during laparoscopic TME. This complication may be important in a transanal approach, and surgeons performing taTME need to be aware of this potential event to prevent major morbidity. Here, we report our experience with 2 patients who had a sudden drop in end-tidal carbon dioxide (ETCO2) that was suspected to be due to CO2 embolism during taTME.
The patient was a 54-year-old man with low...
