Dr. Thomas G. Shanahan, MD.


Just after Thanksgiving last year Dr. Thomas Shanahan, a radiation oncologist fought to save the life of Mary Reindl, 78, who other doctors had decided only had 24 hours to live with advanced lung cancer and chronic obstructive pulmonary disease. Reindl arrived at Memorial Medical Center with abdominal bloating and labored breathing. Shanahan reviewed her case and treated her with a simple resolution. He had a nurse remove eight liters of gas from her colon. The gas was apparently compressing her diaphragm, causing the labored breathing. Other doctors disagreed with Shanahan. A colorectal surgeon had agreed to perform a colonoscopy, but refused to perform the gas release. Doctors, who had previously taken Mary Reindl off of oxygen and increased her pain medication with the expectation of her death within 24 hours, even called in the patient’s son to dispute Shanahan’s change in treatment. The doctors called Shanahan’s plan futile. Mary Reindl’s labored breathing was relieved and she lived for seven months following the colorectal gas release performed by a nurse. The other doctors complained that Shanahan was ‘disruptive’ and ‘abrasive’ during the ordeal. There was apparently some animosity after case. Shanahan moved from Memorial Medical Center to St. John’s Hospital after his lifesaving disagreement with doctors at Memorial Medical Center.

Shanahan also served temporarily as a Springfield alderman, replacing Frank Edwards (husband of the coroner, Cinda Edwards), who became acting mayor after the suicide of Mayor Tim Davlin, who committed suicide in December 2010.

Shanahan’s death is being investigated in the case, which police describe as an apparent suicide.
