•Air under hemidiaphragm bilaterally could be
caused by many conditions such as perforated
peptic ulcer, perforated diverticulum, or
abdominal trauma.
•This condition may require surgery to treat the
condition that caused the free air to be under the
diaphragm.
• The longer treatment (generally surgery) is
delayed the more serious the patient’s health
status may become with peritonitis and sepsis.

Management of the identified process
Treatment of jaundice in this patient
requires the removal of the gallstone.
Laparoscopic surgery to remove the bile
duct obstruction could be performed. The
patient could also be given medications
that would dissolve the gallstone. This
may be useful in patients who can not
tolerate surgery.
