Pneumothoraces in association with laparoscopy are uncommon and potentially disastrous complications that may also occur without adverse sequelae. The "floppy diaphragm sign" is a readily discernible and useful sign of a laparoscopic-induced pneumothorax. Tube thoracostomy is generally not indicated in stable patients as the pneumothorax typically resolves quickly upon desufflation of the pneumoperitoneum.
