Follow-up abdominal computed tomography after splenic trauma in children may not be necessary.
Nonoperative management of splenic injuries in children is well accepted. However, the need for follow-up abdominal CT to document splenic healing has not been well studied. We retrospectively reviewed initial and follow-up abdominal CT examinations of pediatric patients admitted to our institution with documented splenic trauma who were managed nonoperatively. ⋯ The remaining patient's spleen was radiologically considered to have a grade III defect 91 days from the time of injury, and no further CTs were obtained. Of the 34 patients who underwent follow-up CT imaging until splenic healing was demonstrated the mean time to complete healing was 87 +/- 8 days postinjury (range 11-217 days). These data suggest that routine follow-up abdominal CTs may not be necessary to allow children to resume their normal activities after an appropriate time of restricted activity.

Review Case ReportsPseudohyperkalemia secondary to postsplenectomy thrombocytosis.
Hyperkalemia is a regularly encountered electrolyte abnormality. Less commonly recognized is pseudohyperkalemia. In vitro clotting results in the release of potassium from the formed elements of blood; this falsely elevates the serum potassium concentration. ⋯ The serum potassium showed a concomitant rise with the evolution of the patient's postsplenectomy thrombocytosis. This is a case report of our patient and a literature review of this rarely reported and underestimated cause of a potentially serious electrolyte abnormality. We found through our patient that pseudohyperkalemia does occur in the postsplenectomy population and that this should be included in the differential diagnosis of any patient with an elevated serum potassium level and thrombocytosis.

The purpose of this study was to evaluate the impact of adjuvant chemotherapy on survival after surgery for T3N0 colon cancer. All patients with node-negative (N0) colon cancer with tumor invasion beyond the muscularis propria (T3) treated with colectomy between 1982 and 1995 at a single institution were included. Patients were divided into two groups depending on postcolectomy treatment with or without adjuvant chemotherapy. ⋯ Statistical analysis (Mantel-Cox) showed no significant difference between the groups on the basis of survival (P = 0.3743). We conclude that resection alone is a highly effective treatment for T3N0 colon cancer leaving limited opportunity for adjuvant chemotherapy to significantly impact survival. Adjuvant chemotherapy for T3N0 colon cancer patients should be limited to patients enrolled in clinical trials designed to identify subgroups of T3N0 colon cancer patients at a survival disadvantage or less toxic adjuvant chemotherapies.

Nonoperative management of blunt splenic and hepatic trauma in the pediatric population: significant differences between adult and pediatric surgeons?
Although operative management was the preferred method of treating blunt abdominal trauma in the past, recent literature and practice recommend a nonsurgical approach to most pediatric splenic and hepatic injuries. The majority of data supporting the safety and efficacy of this nonoperative approach are derived from university trauma programs with a pediatric center where care was managed by pediatric surgeons only. To evaluate the applicability of this approach in a regional trauma center where pediatric patients are managed by pediatric and non-pediatric surgeons we reviewed the experience at a Level II community trauma center. ⋯ Both developed splenic pseudocysts after splenic injury, which required later operative repair. These data are comparable with those from university trauma programs and confirm that nonoperative management is safe in a community trauma center. The majority of children with blunt splenic and hepatic trauma can be successfully treated without surgery, in a regional trauma center treated by nonpediatric trauma surgeons, if the decision is based on careful initial evaluation, aggressive resuscitation, and close observation of their hemodynamic stability.

The purpose of this study was to examine the effect of operative versus nonoperative management of blunt hepatic trauma in children including transfusion practices. We reviewed the experience at our American College of Surgeons-verified Level I trauma center with pediatric commitment over a 5-year period. Children < or = 16 years of age suffering blunt liver injury as documented on admission CT scan were included in the study. ⋯ No patients in the study died, three were transferred to subacute rehabilitation, one was transferred to another hospital, and 23 were discharged home. Our findings indicate that a majority of children with blunt hepatic injury as documented on CT scan can be managed with nonoperative treatment, and few require blood transfusions. Patients with multiple organ injury including simultaneous splenic injury are likely ideally managed through operative exploration and repair, whereas those with isolated liver injuries can be successfully managed nonoperatively.
