Gastric bypass in a factor V deficient patient.

Factor V deficiency is a rare bleeding disorder requiring special attention during the peri-operative period. Surgical intervention in these patients can be technically challenging. Because of the rarity of this condition, the optimal management is unknown. Available literature supports peri-operative infusion of fresh frozen plasma. We report successful management of a factor V deficient patient undergoing Roux-en-Y gastric bypass. Literature review indicates that this is the first reported case of bariatric surgery in a patient with factor V deficiency.

Superior mesenteric artery syndrome and aortic aneurysm

The association of superior mesenteric artery syndrome and aortic abdominal aneurysm is a rare event, less than 25 cases were reported. Objective - to describe two cases of the aforementioned association. Cases report -case 1 - a 66 years old white man whose first manifestation of the aneurysm was the duodenal obstruction with a fatal outcome before treatment was possible / A associação da síndrome da artéria mesentérica superior e o aneurisma de aorta abdominal é rara, menos que 25 casos foram descritos.

Safety of cystic duct clipping in healthy and cirrhotic livers: a cadaveric study.

BACKGROUND AND OBJECTIVES: Biliary leakage through the cystic duct stump due to clip dislodgement has been a concern since the advent of the laparoscopic cholecystectomy. The authors proposed a cadaveric model to test the safety of cystic duct clipping in a hypertensive biliary tract in healthy and cirrhotic livers. METHODS: Twenty fresh cadavers were studied (5 cirrhotic, 15 healthy). Open cholecystectomy was performed and the cystic duct clipped with commercially available titanium clips. The distal common bile duct was catheterized to allow infusion of water and pressure measurement. RESULTS: Increased pressure in the bile duct resulted in back diffusion into the liver, preventing reaching high-pressure levels. Only 1 clip was dislodged in this situation, in a cirrhotic liver with a large cystic duct. As a second experiment, the hepatic hilum was clamped to allow higher pressures of the biliary tree (500 mm Hg). In this situation, no clip was dislodged. CONCLUSIONS: We have established the safety of cystic duct clipping in healthy and cirrhotic livers; however, bigger clips or alternative methods to seal the duct may be necessary in larger ducts.

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%.
