Objective: To investigate the safety and effectiveness of extraluminal placement of a bronchial blocker compared with carbon dioxide (CO) artificial pneumothorax in infants undergoing video-assisted thoracoscopic surgery (VATS).
Methods: The study involved 33 infants (group A) who underwent one-lung ventilation (OLV) with extraluminal placement of a bronchial blocker and 35 other infants (group B) who underwent CO artificial pneumothorax. Clinical characteristics, the degree of lung collapse, and complications were compared.
Results: The degree of lung collapse in group A was significantly higher than that in group B at T2 and T3. The mean arterial pressure (MAP) of group B was significantly lower than that of group A at 10 min and 30 min after OLV. The partial pressure of carbon dioxide (PaCO) of group B was significantly higher than that of group A at 30 min after OLV. The incidence of hypotension in group B was higher than that in group A.
Conclusion: Compared with CO artificial pneumothorax, extraluminal placement of a bronchial blocker is associated with a better degree of lung collapse, fewer episodes of hypotension, and lower PaCO accumulation during OLV in infants undergoing VATS.

: Anastomotic insufficiencies (AI) and perforations of the upper gastrointestinal tract (uGIT) result in high morbidity and mortality. Endoscopic stent placement and endoluminal vacuum therapy (EVT) have been established as surgical revision treatment options. The Eso-Sponge is the only licensed EVT system with limitations in treating small defects (<10 mm).

Pneumoperitoneum is often treated as a surgical emergency as the most common etiology is perforated hollow viscus. Here, we present the case of a man in his 70s who presented to the emergency department with fever and abdominal pain. On physical exam, he was diffusely tender in the bilateral lower quadrants with guarding.
