RESUMO
Introduction: Duodenal trauma is rare but can be associated with significant morbidity and mortality (Pandey et al., 2011). Adjunct procedures, such as pyloric exclusion, can be performed to assist in surgical repair of these injuries. However, pyloric exclusion can lead to severe long-term complications associated with significant morbidity that can be difficult to repair. Case: A 35-year-old man with a history of duodenal trauma from a gunshot wound (GSW) status post pyloric exclusion and Roux-en-Y gastrojejunostomy presented to the Emergency Department (ED) with complaints of abdominal pain and leakage of food particles and fluid from an open wound around his surgical scar. Computed tomography (CT) scan on admission showed a tract extending from the gastrojejunostomy anastomosis to the skin representing a fistula. Esophago-gastro-duodenoscopy (EGD) reconfirmed a large marginal ulcer that had fistulized to the skin. After nutritional repletion, the patient was taken to the operating room (OR) for takedown of the enterocutaneous fistula and Roux-en-Y gastrojejunostomy, closure of gastrostomy and enterotomy, pyloroplasty and feeding jejunostomy tube placement. The patient was re-admitted after discharge with abdominal pain, vomiting and early satiety. EGD showed gastric outlet obstruction and severe pyloric stenosis which was managed with endoscopic balloon dilation. Conclusion: This case represents the severe and potentially life-threatening complications that may occur after pyloric exclusion with Roux-en-Y gastrojejunostomy. Gastrojejunostomies are prone to marginal ulceration which can perforate if not adequately treated. Free perforations cause peritonitis, but if the perforation is contained it can erode through the abdominal wall creating the rare complication of a gastrocutaneous fistula. Even after restoration of normal anatomy with a pyloroplasty, patients may suffer additional complications such as pyloric stenosis requiring continued intervention.
RESUMO
BACKGROUND: The incidence and propagation of thrombosis involving vessels distal to the popliteal vein has not been clearly defined in trauma patients. Our aim was to determine the incidence and rate of propagation of infrageniculate deep venous thrombosis (DVT) in a trauma population and identify potential risk factors specific to propagation. METHODS: Retrospective review of all trauma admissions between the years 2001 and 2003 was conducted. Only those 18 years or older with an isolated infrageniculate DVT who underwent a lower extremity venous duplex scan during admission were included in the study. Nature of injury, injury severity score (ISS), method of DVT prophylaxis, thrombus location, and risk factors for hypercoagulable states were recorded. RESULTS: During the study period, 698 trauma admissions were included, and 109 (15.7%) with infrageniculate DVT were identified. Thirty-nine (35.7%) had thrombus propagation (14 suprageniculate and 25 infrageniculate) with a mean ISS of 27.6. Seventy (64.3%) had infrageniculate DVT without propagation and a mean ISS of 19.6. Thirty-eight (97%) patients with propagating infrageniculate DVT had received mechanical prophylaxis, and 33 (84%) also received chemical prophylaxis. The 14 patients with suprageniculate thrombus propagation were the most severely injured (mean ISS = 35.1). Elevated ISS, operation, age < or =62 years, and intensive care unit admission were positively correlated with propagation of infrageniculate DVT. CONCLUSION: The incidence and propagation of infrageniculate DVT in an aggressively prophylaxed trauma population are greater than previously reported. The clinical significance of isolated infrageniculate DVT remains to be determined, but when associated with a multiple injury trauma, the patient may be at risk for future suprageniculate DVT formation and may benefit from therapeutic anticoagulation.
