Episode 1
Fecal Impaction Misdiagnosed as Bowel Obstruction

Diagnosis: Upon further examination (specifically a rectal exam mandated by Dr. Benton), the diagnosis was revised to severe Fecal Impaction. Treatment: Instead of surgery, the patient required manual disimpaction, a humbling task assigned to Dr. Carter.
