Analysis of 29 consecutive thoracoscopic repairs of congenital diaphragmatic hernia in neonates compared to historical controls.

PURPOSE: The applicability of minimally invasive surgical techniques to pediatric surgical diseases continues to grow. Surgeons have hesitated to apply these methods to congenital diaphragmatic hernia (CDH) of Bochdalek because of the disease-associated pulmonary hypertension and patient fragility. We began performing thoracoscopic repair (CDH-T) in 2004 and have since completed 29 sequential repairs. To evaluate feasibility and outcomes, we compared this experience to a historical control group who underwent open repair (CDH-O) at the same institution by the same surgeons from 2001 to 2004. METHODS: From January 2001 through November 2007, 72 neonates were evaluated jointly by the Neonatology and Pediatric Surgical services for CDH. Fifteen infants died before any corrective operation and were excluded from analysis. Demographics including gestational age, birth weight, Apgar scores, percent outborn, usage of extracorporeal life support, and associated anomalies were recorded. End points were complications, additional operative procedures, initial patch closure, recurrence, length of stay in non-extracorporeal membrane oxygenation patients, and postoperative mortality. RESULTS: Demographic characteristics were similar between the 2 groups. There were no statistically significant differences in complications (71.5% vs 55%, P = .28), additional related operative procedures (42.9% vs 34.5%, P = .59), use of prosthetic patch (42.8% vs 51.7%, P = .60), recurrence (6.9% vs 20.7%, P = .25), length of stay (24 vs 34 days, P = .11), or postoperative mortality (21.4% vs 6.9%, P = .14) between the CDH-O and CDH-T groups, respectively. There was one conversion in the CDH-T group (3.4%). CONCLUSIONS: To our knowledge, this is the largest reported series of CDH-T of neonatal CDH of Bochdalek. We have demonstrated the feasibility of performing this procedure thoracoscopically in an unselected population including children who have undergone prior extracorporeal life support. These results compare favorably with CDH-O, although further follow-up is required to determine the durability of the approach.

Minimally invasive management of the prenatally torsed ovarian cyst.

BACKGROUND: Fetal and neonatal ovarian cysts are detected frequently by ultrasonography. The presence of these lesions can result in adnexal torsion in utero with autoamputation. Historically, these have been removed at laparotomy. METHODS: Retrospective chart review was performed at a single children's hospital from October 1996 to September 2001. RESULTS: Six cases of torsion of ovarian cysts were removed laparoscopically. Five of the 6 patients had prenatal ultrasound diagnosis. The sixth had the cyst detected incidentally by magnetic resonance imaging (MRI) at 3 months of age. All cysts were complex by ultrasound criteria. All 6 procedures were performed via a 2-port laparoscopic approach. The average age at surgery was 3.7 months (range, 9 days to 7.5 months). There were no postoperative complications. Five patients were discharged on the day of surgery. CONCLUSION: Laparoscopy offers a safe, effective, and cosmetic means of managing perinatal torsion of ovarian cysts.
