Public health lessons learned from analysis of New York City subway injuries.

Serious subway injuries are devastating to their young victims and have high rates of mortality and amputation. We identified the urban population at greatest risk for subway injuries and investigated the influence of local economies on injury rates. We propose using changes in social conditions as a "trigger" for increased vigilance and protective measures at times of higher risk.

Devastating consequences of subway accidents: traumatic amputations.

The efficiencies of the subway system are tempered by the occurrence of accidents, some with devastating injuries. The purpose of this study is to examine our experience with traumatic amputations after subway accidents. A retrospective trauma registry review (1989-2003) of 41 patients who presented to Bellevue Hospital, New York City, with amputations from subway accidents was undertaken to examine the following end points: age, sex, Injury Severity Score, time and mechanism of accident, history of psychiatric disorders and alcohol use, admission vital signs, Glasgow Coma Scale score, amputation type, associated injuries, limb salvage rate, operative procedures, mortality, and disposition. Elevated alcohol levels and prior psychiatric diagnoses were present in 39 per cent and 17 per cent of the patients, respectively. Patients were stable on admission with a mean systolic blood pressure of 114 mmHg, hematocrit of 32, and Glasgow Coma Scale score range of 13 to 15. The most common amputation was below knee, and patients underwent an average of three operative procedures. Limb salvage was attempted in eight patients with no successes. Amputation wound infection rate was 32 per cent and mortality rate was 5 per cent. Victims of subway trauma who arrive at the hospital with devastating amputations have an excellent chance of surviving to discharge.

Indications for splenectomy.

In the new millennium, indications for splenectomy have expanded. Proper patient selection based on an understanding of the biology of each individual's disease is essential for a favorable outcome. We review the most common diseases for which surgeons may be called on to perform splenectomy and while highlighting potential pitfalls and caveats.

Stercoral colitis leading to fatal peritonitis: CT findings.

OBJECTIVE: Stercoral colitis is an inflammatory process involving the colonic wall related to fecal impaction. Our purpose was to describe the imaging findings of stercoral colitis and ulceration and to emphasize the potential serious clinical implications of the condition. CONCLUSION: Fecal impaction may lead to ischemic pressure necrosis and subsequent colonic perforation. In the appropriate clinical setting, the imaging findings that should prompt the radiologist to consider this diagnosis are the presence of fecal impaction, focal colonic wall thickening, and adjacent stranding of the fat. If the fecal impaction is not promptly relieved, the condition can lead to colonic perforation, peritonitis, and patient demise.

Successful treatment of Bouveret syndrome using holmium: YAG laser lithotripsy.

Although gallstone disease is highly prevalent, cholelithiasis causing gallstone ileus is uncommon. Consideration has been given for nonoperative strategies to resolve obstruction due to the significant age and comorbidities afflicting this population. A 94-year-old man presented with a 5-day history of abdominal distension and tenderness. CT scan revealed multiple large gallstones within the gallbladder, pneumobilia, and two ectopic gallstones (antrum of the stomach and distal ileum). The patient was taken to the operating room where an enterolithotomy and gastrotomy was performed with removal of gallstones and subsequent relief of obstruction. During the postoperative course, the patient developed symptoms of gastric outlet obstruction and underwent gastrointestinal endoscopy for diagnosis and treatment. Two large gallstones, present in the duodenum, were retracted into the stomach using a Roth net but could not be retrieved beyond the upper esophageal sphincter. A holmium: yttrium-aluminum-garnet (Holmium: YAG) laser was used for fragmentation of the stones, with subsequent successful removal. This is the first documented successful use of the holmium: YAG laser for the treatment of recurrent gallstone ileus. Physicians should remember that in a small but important subgroup of patients, endoscopy accompanied by laser lithotripsy may prove beneficial.

Two New York City hospitals' surgical response to the September 11, 2001, terrorist attack in New York City.

BACKGROUND: We describe the surgical response of two affiliated hospitals during the day of, and week following, the September 11th, 2001 terrorist attack at the World Trade Center in New York City. The city of New York has 18 state designated regional trauma centers that receive major trauma victims. The southern half of Manhattan is served by a burn center, two regional trauma centers, and a community hospital that is an affiliate of one of the regional trauma centers. This report accounts for the surgical response by a regional trauma center (Hospital A, located 2.5 miles from the World Trade Center) and its affiliate hospital (Hospital B, located 5 city blocks from the World Trade Center) on September 11th when two commercial jets crashed into the Twin Towers at the World Trade Center mall. METHODS: Hospital A maintained a concurrent log of patients received during the first 5 hours, the first day, and the first week after the disaster which was kept by the Surgical Triage Officer. The trauma registry completed and verified this data by September 18th. Hospital B collected its data by hand counting and verification by chart review. Both hospitals, A and B, had established disaster plans that were implemented. RESULTS: Nine hundred eleven patients were received by two affiliated hospitals from the World Trade Center attack. Seven hundred seventy six patients (85%) were walking wounded, sustaining mild inhalation and eye irritant injuries. One hundred thirty five (15%) were admitted with 18 (13%) of these undergoing surgery. Twenty two of the 23 transfers were from the community hospital to specialized orthopedic or burn centers. Of the 109 patients admitted to Hospital A, 30 were to the surgical service. The mean ISS score of these patients was 12. There were 4 deaths (within minutes of arrival at the hospital) and 6 delayed deaths (day 1-14). Excluding walking wounded and DOAs, the critical mortality rate was 37.5% overall. CONCLUSION: The September 11th, 2001, terrorist attack in New York City, involving two commercial airliners crashing into the World Trade Center, led to 911 patients received at two affiliated hospitals in lower Manhattan. One hospital is a regional trauma center and one was an affiliate community hospital. Eighty five percent of the patients received were walking wounded. Of the rest, 13% underwent surgical procedures with an overall critical mortality rate of 37.5%.
