Splenic Injury as a Complication of Robotic-Assisted Thoracic Surgery.

Splenic injury after thoracic surgery is rare and has not been reported following robotic-assisted thoracic surgery (RATS). We describe a 52-year-old woman who underwent RATS left upper lobectomy. After discharge, she returned with abdominal pain and hypotension. Computed tomography revealed hemoperitoneum with signs of splenic injury. Emergent laparoscopic splenectomy confirmed splenic rupture. This case highlights that unrecognized intraabdominal trauma can occur during RATS; surgeons should exercise caution near the diaphragm and remain vigilant post-discharge.
