Photographs of William W. Keen’s successful operation to remove a brain tumor from a 26-year old patient, 1887. The patient was a carriage maker who exhibited symptoms of severe headaches, seizures, and partial blindness; he also had a history of a head injury and was prone to aphasia.
Owing to Keen’s demands at that proper antiseptic measures were taken for the operation (including removing the carpet and cleaning walls and ceiling), the tumor was removed after a two hour operation. Despite some complications with wound closure and cerebrospinal fluid leak, the patient lived for thirty years, even donating his brain to his surgeon for anatomical study.

Two arms hinged and closed by a screw nut form an
oval-like ring, accompanied by the serrated teeth of two longer arms. The
penis was kept out of harm’s way by insertion through the oval, while
the teeth sliced away the skin between the scrotum and the body.
The term volvulus is derived from the Latin word volvere (“to twist”). A colonic volvulus occurs when a part of the colon twists on its mesentery, resulting in acute, subacute, or chronic colonic obstruction. The main types of colonic volvulus are sigmoid volvulus and cecal volvulus.
