Lesión duodeno-ureteral compleja por herida de arma de fuego: diagnóstico y resolución quirúrgica / COMPLEX DUODENAL-URETERAL LESION DUE TO FIREARM INJURY, DIAGNOSIS AND SURGICAL RESOLUTION

Las lesiones traumáticas duodenales son infrecuentes pero producen una tasa de morbi-mortalidad significativa. Se debe tener presente la elevada frecuencia de lesiones asociadas, siendo las de uréter superior las más frecuentes. Masculino de 50 años ingresa por HAF paravertebral derecha. Al ingreso OTE, lucido, vigil, con dolor y defensa abdominal generalizada. En la TC toracobdominal con cte EV y VO se objetiva extravasación de contraste oral a nivel duodenal y en fase excretora renal derecha.Se decide Laparotomía de urgencia objetivando lesión transfixiante de 2da porción de duodeno de < 50% de su circunferencia y sección de uréter derecho proximal. Se realiza rafia en dos planos de duodeno, colocación de pig tail y anastomosis T-T de uréter derecho mas drenaje. Buena evolución postquirúrgica con control tomográfico a las 72 hs sin objetivar fuga. Alta hospitalaria al 6to día. El traumatismo duodenal es una patología rara que se asocia con una tasa considerable de morbimortalidad, su localización retroperitoneal puede hacer que los clásicos signos de peritonismo no estén presentes en el momento de la evaluación, por lo que se recomienda la realización de exámenes clínicos seriados y de estudios complementarios con contraste VO y EV. Las lesiones ureterales asociadas son las más frecuentes. La mayoría tienen una pérdida mínima de tejido, siendo usualmente reparadas mediante desbridación y anastomosis.

Duodenal traumatic injuries are rare but produce a significant morbidity and mortality rate. The high frequency of associated lesions should be kept in mind, with those of the upper ureter being the most frequent. 50-year-old male enters for right paravertebral HAF. At hospital admission, lucid patient and vigil. Thoracoabdominal CT with intravenous and oral contrast show extravasation of oral contrast at the duodenal level and in the right renal excretory phase. Emergency laparotomy is decided by objectifying transfixing lesion of the 2nd portion of the duodenum of <50% of its circumference and proximal right ureter section. Raffia is performed in two planes of the duodenum, placement of pig tail and TT anastomosis of the right ureter plus drainage. Good post-surgical evolution with tomographic control at 72 hours without objectifying leakage. Hospital discharge on the 6th day. Duodenal trauma is a rare pathology that is associated with a considerable morbidity and mortality rate, its retroperitoneal location may make the classic signs of peritonism not present at the time of the evaluation, so clinical exams are recommended series and complementary studies with VO and EV contrast. Associated ureteral lesions are the most frequent, Most have minimal tissue loss, usually repaired by debridement and anastomosis.

Empalamiento precordial por arma blanca: extracción bajo visión videotorcoscópica / PRECORDIAL REMOVAL OF AN IMPALED KNIFE UNDER THORACOSCOPIC VISION

Background: It is widely established that the extraction of impaled objects should be carried out under direct vision. In the case of stable patients, endoscopic vision can be used as an alternative. Clinical Case: A 70-year-old male is admitted for a 5-hour impaled precordial stab wound. Evolution valued according to ATLS standards. Clinically and hemodynamically compensated patient. On physical examination: left pulmonary hypoventilation, subcutaneous emphysema, no jugular engorgement. Control of vital signs: TA: 110 / 70mmHg, FC: 70min, FR: 20min, Sat02: 97%. Complementary studies: ECO FAST: no pericardial fluid. Rx thorax: mild left pneumothorax heme. Chest CT: Puncture object of 18 cm in the left lung of AP and medial to the lateral path, hematoma of the angle, and hemopneumothorax grade I. Surgery: Patient in dorsal recumbency, under ARM with selective intubation. An incision in 5th left intercostal space, middle axillary line. 10mm trocar placement, 30 ° optics introduction. After discarding the commitment of the pericardium, active bleeding, and observing that the end of the weapon was going through the end of the angle, the weapon is removed under endoscopic vision. Clot washing/aspiration. Verification of hemostasis, absence of air leakage and pulmonary expansion. Drainage with 28 French tubes. Evolution: Derived from UTI extubated. CT scan thorax 72 h post: small intraparenchymal hematoma left, expanded lung. Minimum serohematic debit. Pleural tube and definitive discharge are removed on the 4th post-surgical day. Discussion: The literature suggests in the urgency, the removal of impaled objects under direct vision of the compromised structures. However, in stable patients, the previous study with CT should be unavoidable. Video-thoracoscopy in these wounded can avoid open surgery, but the procedure must be performed in trauma reference centers, with the appropriate means and by a trained surgical team willing to perform an emergency thoracotomy
