Factors Influencing the Distance That Oral Contrast Travels in Patients with Blunt Abdominal Trauma as Determined by Abdominal CT Scan

The medical records of 43 hemodynamically stable children with elevated serum transaminase levels (aspartate aminotransferase [AST] and alanine aminotransferase [ALT]) who underwent abdominal computed tomographic (CT) scan for blunt abdominal trauma were reviewed. Nineteen patients (44.2%) had AST levels >450 IU/L and ALT levels >250 IU/L, and 17 of these 19 patients had hepatic injury identified on abdominal CT scan. Of the 43 patients, 25 (58.1%) had AST and ALT levels of less than 450 IU/L and 250 IU/L, respectively, and none of these patients had evidence of hepatic injury on CT scan. Elevated serum transaminase levels (AST >450 IU/L and ALT >250 IU/L) identified all of the patients with hepatic injury visible on abdominal CT scan. The sensitivity and specificity of elevated serum transaminase levels were 100% and 92.3%, respectively, for predicting hepatic injury. It is recommended that hemodynamically stable pediatric patients with blunt abdominal trauma and AST levels >450 IU/L and/or ALT levels >250 IU/L undergo abdominal CT scan to determine the presence and extent of hepatic injury. Children with serum transaminase levels below these values are at decreased risk of liver injury.

Multiple Injury Patients

Multiple injury patients with blunt abdominal trauma (n = 110) were examined by abdominal CT. An i.v., but not peroral, contrast medium was used, thereby eliminating the delay caused by administering peroral contrast medium and any subsequent delay in making the diagnoses and beginning operative treatment. Eighteen patients underwent emergency laparotomy after the initial CT examination. The preoperative CT findings were compared to the laparotomy findings. CT revealed all but one of the severe parenchymal organ lesions requiring surgery. The one liver laceration that went undetected had caused hemoperitoneum, which was diagnosed by CT. The bowel and mesenteric lesions presented as intra-abdominal blood, and the hemoperitoneum was discovered in every patient with these lesions. Fourteen patients also initially had positive abdominal CT findings; 10 of them underwent an additional abdominal CT within 3 days, but the repeat studies did not reveal any lesions in need of surgery. Omission of the oral contrast medium did not jeopardize making the essential diagnoses, but it did save time.

Renal trauma in children is more common than in adults. Clinically in pediatric patients with renal trauma do not always describe the degreeof trauma. Radiological examination, especially abdominal CT-scan with contrast, can help evaluate the damage to the kidneys so that it candetermine the degree of trauma.

Tract Infections

AbstractOrgan abscesses caused by Streptococcus anginosus are relatively rare. We report the case of an elderly woman with splenic abscess caused by S. anginosus bacteremia after urinary tract infection. An 82-year-old woman had a history of frequency of urination, urgency, and fever with chills for over 10 days prior to admission. An abdominal computed tomography (CT) scan performed in the emergency room revealed a low-density lesion in the spleen, kidney cysts, some exudation around the kidney, and cystitis should be valued. She was treated with ceftriaxone and imipenem/cilastatin. After admission, the blood culture yielded positive results for S. anginosus. A contrast-enhanced abdominal CT scan showed that the low-density lesion previously found in the spleen was smaller than before. After percutaneous drainage of the splenic abscess and treatment with piperacillin/tazobactam based on the antibiotic sensitivity pattern, repeated abdominal CT scan revealed a significant reduction in the low-density lesion. The patient was discharged without recurrence or complications. A systematic review of organ abscess caused by S. anginosus bacteremia was performed. To our knowledge, there has been no report of splenic abscess caused by S. anginosus bacteremia secondary to urinary system tract infection, although urinary tract infections are also an important source.

Abstract Background Small intestine duplication cysts (SIDCs) are rare congenital anatomical abnormalities of the digestive tract and a rare cause of hematochezia. Case presentation We describe an adult female presented with recurrent hematochezia. The routine gastric endoscope and colonic endoscope showed no positive findings. Abdominal CT scan indicated intussusception due to the "doughnut" sign, but the patient had no typical symptoms. Two subsequent capsule endoscopes revealed a protruding lesion with bleeding in the distal ileum. Surgical resection was performed and revealed a case of SIDC measuring 6 * 2 cm located inside the ileum cavity. The patient remained symptom-free throughout a 7-year follow-up period. Conclusion SIDCs located inside the enteric cavity can easily be misdiagnosed as intussusception by routine radiologic examinations.
