[Experience in management of trauma-related acute abdomen at the "General Ignacio Zaragoza" Regional Hospital in Mexico City]. / Experiencia en el manejo del abdomen agudo de origen traumático en el Hospital Regional "General Ignacio Zaragoza"

OBJECTIVE: To know the current state of surgical management of patients with abdominal trauma. MATERIAL AND METHODS: We carried out a retrospective, observational, transversal study involving patients with abdominal trauma with clinical files wtih trauma who required surgery during the period of April 1, 1998 through March 30, 2003. RESULTS: There were 72 cases including nine male and 33 female patients. Mechanism of lesion was divided into closed and penetrating trauma, the latter group of patients divided into individuals with blunt wounds or with gunshot wounds. Most frequent early postoperative complication was hemorrhage, while most frequent late postoperative complication was acute renal failure. Causes of death were hypovolemic shock in four patients followed by two cases each with the following pathologies: acute respiratory insufficiency syndrome; myocardial infarct, and septic shock. CONCLUSIONS: Abdominal trauma is a frequent pathology in our environment, males the most affected patients, with penetrating trauma main lesion cause. Prolonged surgical time required hemotransfusions, and infectious processes together with processes related with tissular hypoxia are the most common cause of complications and death.

[Results of 21 years of surgery in iatrogenic lesions of the bile ducts]. / Resultados a 21 años de la cirugía para lesión iatrogénica de la vía biliar.

OBJECTIVE: To report our results with surgical procedures for treatment of iatrogenic injuries of bile duct. SETTING: Tertiary-level health care hospital. DESIGN: Retrospective, observational, and descriptive study. MATERIAL AND METHOD: We studied all patients operated on due to iatrogenic of injuries of the bile duct over the last 21 years (1980-2001). We analyzed the following variables: age; gender; previous bile duct surgical procedure; auxiliary diagnosis; type of bile duct injury according to Bismuth's classification; surgical procedure used; non-related mortality, and postoperative morbimortality. RESULTS: Fifty four patients were operated on (46 female, eight male) ranging from 19 to 71 years of age; 39 were sent to the hospital, 15 were injured at the hospital in 7,098 gallbladder and bile duct procedures (0.21%), 83.3% in open cholecystectomy, and 16.6% in laparoscopic cholecystectomy. In 86% of cases, diagnosis was made by percutaneous cholangiography and injuries types were: I = 13%, II = 26%, III = 50%, IV = 9.2%, and V = 1.8%. Roux-en-Y intrahepaticojejunostomy was the most common procedure (51.9%) followed by hepaticojejunostomy (37%). Of 54 surgical patients, five died due to situations unrelated to bile duct illness, and they were cared for more than one year without complications; 46 patients (85.2%) did not show strictures, three patients (5.5%) were reoperated on because of strictures, all without recurrent strictures for more than one year of care, with a total of good results of 90.7%; mortality: four patients (7.2%), and complications after procedure: 11%. Strictures were developed during the first year after surgical procedure. CONCLUSION: Our results are similar to others found in researches from Mexico and other countries; therefore, we recommend long-term care of patients.
