Transabdominal manually assisted reduction of pediatric intussusception: reappraisal of this historical technique.

PURPOSE: To determine whether manual manipulation of the abdomen during intussusception reduction improves the success rate or affects morbidity. MATERIALS AND METHODS: A retrospective study was performed in 38 cases of intussusception in 35 children over a 33-month period at a pediatric hospital. In all cases, pneumostatic pressure was used as the initial method of treatment. A comparative review of the intussusception literature was also performed. RESULTS: Reduction was achieved with pneumostatic pressure alone in 22 cases (an initial success rate of 58%). Transabdominal manual manipulation was used in 10 cases after initial pneumostatic reduction failed; seven of these 10 cases were treated successfully. These seven additional successes, attributed to manual assistance, significantly improved the success rate from 58% to 76% (P < .016). No perforation or other complication occurred. CONCLUSION: These results and findings of the literature review indicate that transabdominal manual assistance during reduction is a potentially useful technique that has been shunned without scientific basis for longer than 40 years.

CO2 laser urethroplasty in the rabbit: a preclinical model.

Our previous work has shown that the CO2 laser can be successfully used in urethral reconstruction in a rat model. This new experiment investigates the use of the CO2 laser to perform a patch graft urethroplasty in the rabbit, as a preclinical model to its use in the repair of hypospadias in humans. Using sterile technique, a patch graft of preputial skin was welded in the repair of a standardized urethral defect in 10 rabbits. In another cohort, the same urethral defect was repaired using standard microsuture technique. In a control group the patch graft was placed with microsuture in a nonwatertight fashion. All animals were followed for 3 weeks. Histologic and radiologic analyses were done in a blinded fashion. Our study showed that CO2 laser repair, when compared to microsuture in urethral reconstruction, required 40% less operative time and produced better graft healing and less intraluminal scarring.

Aortic pseudoaneurysm due to ingested foreign body.

We have described a child with pseudoaneurysm of the thoracic aorta caused by an ingested safety pin, who survived this life-threatening injury in which the diagnosis was elusive for four months. Esophageal foreign bodies, especially sharp, pointed ones, can cause such a cardiovascular complication. A high index of suspicion is imperative if the diagnosis is to be made early. Serial chest x-ray films showing an enlarging mediastinal mass should trigger aggressive radiologic evaluation.
