Prenatal diagnosis of congenital cystic adenomatoid malformation and its postnatal presentation, surgical indications, and natural history.

BACKGROUND/PURPOSE: Regression of a cystic adenomatoid malformation (CAM) in a fetus is well described. Little, however, is known about the postnatal course of these infants. This study attempts to correlate the prenatal course of CAMs with postnatal symptoms, radiological manifestations, and need for surgery. METHODS: The clinical course of patients with a CAM diagnosed prenatally were retrospectively reviewed. Inclusion in the study required a prenatal ultrasound scan documenting a CAM. RESULTS: Over 10 years, 14 patients with a CAM were diagnosed prenatally. Six (43%) showed a partial in utero regression. Four patients were symptomatic at birth and underwent a resection as newborns. Ten patients were asymptomatic at birth, and eight of these had normal chest x-rays. Elective resection has been performed in 3 of these 10, and two additional children are scheduled to undergo an excision near 1 year of age. The remaining five patients have undergone follow-up nonoperatively for a mean of 36 +/- 15 months. Of the seven asymptomatic patients not undergoing immediate surgery, only one has shown a slight postnatal regression, despite five of these showing regression in utero. None have become symptomatic. CONCLUSIONS: The results suggest that regression of a CAM on prenatal ultrasound scan is common, but this process does not continue after birth. A normal chest x-ray does not indicate complete regression of a CAM; a computed tomography (CT) scan is required to evaluate such patients, and will generally demonstrate a CAM. Asymptomatic patients with a CAM may be followed up nonoperatively with no apparent adverse effects. The decision and timing of an excision in an asymptomatic patient remains controversial among pediatric surgeons.

Specialty networking in pediatric surgery: a paradigm for the future of academic surgery.

OBJECTIVE: To review retrospectively a 4-year experience with pediatric surgical networking at a major academic medical center in the Midwest. BACKGROUND: The growth of managed care in the United States during the past decade has had a major impact on the practice of medicine in general, but especially on academic medicine. In some academic medical centers, the loss of market share has not only affected clinical activity but has also compromised the educational and research missions of these institutions. METHODS: At the authors' institution, a networking strategy in pediatric surgery was established in 1993 and implemented on July 1, 1994. In 1994, one new satellite practice was established; over the next 4 years, four additional practices were added, including one in another state. To assess the impact on financial status, clinical activity, education, and academic productivity, the following parameters were analyzed: gross and net revenue, surgical cases, clinic visits, ranking of the pediatric surgery residency, publications, grant support, and development and endowment funds. RESULTS: Gross and net revenue increased from $3,273,000 and $302,000 in 1993 to $10,087,000 and $2,826,000, respectively, in 1998. Surgical cases and clinic visits increased from 1240 and 3751 in 1993 to 5872 and 11,604, respectively, in 1998. At the medical center's children's hospital, surgical cases and clinic visits increased from 1240 and 3751 to 2592 and 4729 during the same time period. During this 4-year period, the faculty increased from 4 to 11. Since 1997, the National Resident Matching Program has provided data on how pediatric surgery residency candidates ranked a training program. In 1997, this program received the second-most one to five rankings; in 1998, it tied for first. This exceeds the faculty's perception of previous years' rankings. Publications increased from 26 in 1993 to a peak number of 62 in 1996; in 1997 and 1998 the publications were 48 and 37, respectively. External grant support increased from $139,882 in 1993 to a total of $6,109,971 in 1998. Development and endowment funds increased from $103,559 in 1993 to $2,702,2777 in 1998. CONCLUSIONS: Pediatric surgical networking at the authors' institution has had a markedly positive impact on finances, clinical activity, education, and academic productivity during a 4-year period. The residency training program appears to have improved in popularity among candidates, probably because of the increased referral of complex cases to the medical center from the various networking satellites. External grant support and basic laboratory research significantly increased, most likely because of the greater number of faculty with protected time for research recruited. Development and endowment funds dramatically grew because of the excellent fiscal health of the pediatric surgical program. This experience may serve as a model for other academic surgical specialties.

Can using emergent technology incur liability?

There are numerous areas of potential liability for the practicing surgeon attempting to upgrade skills and introduce emergent technology into his or her practice. The College understands that graduate medical education in a teaching institution, continuing medical education at our College-sponsored venues, and all other sponsored or co-sponsored educational activities each carry risks and benefits. Current College activities are directed toward enhancing translation of emergent surgical technology into clinical practice as effectively, productively, safely, and as free of risk as possible.
