Pediatric extremity bone sarcoma reconstruction with the vascularized fibula flap: Observational study assessing long-term functional outcomes, complications, and survival.

BACKGROUND: Limb salvage is important in pediatric patients with bone sarcomas. The vascularized fibula flap is a versatile option, combined or not with a bone allograft. The authors evaluated the functional long-term outcomes, complications, and survival of using this technique in pediatric patients. METHODS: A retrospective review of 27 pediatric patients reconstructed between 2011 and 2018 with the fibula flap after bone sarcoma resection was conducted. Long-term functional outcomes, complications, and survival were assessed. Variables analyzed were age, sex, Capanna technique, follow-up, complications, additional surgeries, time to weight bearing, length discrepancy, and sport practice. RESULTS: Twenty-seven patients with a mean age of 9.3 years were included. The mean follow-up was 44.33 months. The Capanna technique was performed in 15 patients. All extremities but one were salvaged. The overall complication rate was 74.07%. Fibula fracture and nonunion rates were 34.04% and 11.11%, respectively. Partial weight bearing was resumed at a mean of 9.07 months. About 79.17% of patients with a 12-month follow-up achieved full weight bearing. An age below 8 years was significantly associated with a lower major complication rate and a shorter time to weight bearing and full weight bearing. Major complications and additional surgeries were significantly associated with longer periods until weight bearing and full weight bearing. CONCLUSIONS: The fibula flap allows the majority of extremities to be reconstructed. However, a high rate of complications and additional surgeries should be anticipated. Full weight bearing is usually achieved within the first year, with modest functional increase afterward. Less complications and a faster functional recovery are expected in patients below the age of 8 years.

Chimeric Anterolateral Thigh Flap for Total Thoracic Esophageal Reconstruction.

Gastric pull-up is generally the first choice for a total thoracic esophageal reconstruction. Malfunction of this gastric conduit is uncommon, but devastating when it occurs: it causes marked comorbidity to the patient, preventing oral intake and worsening quality of life. Secondary salvage thoracic esophageal reconstruction surgery is usually performed with free or pedicled jejunum flaps or colon interposition. We present a case of a total thoracic esophageal reconstruction with an externally monitored chimeric anterolateral thigh flap, extending from the cervical esophagus to the retrosternal gastroplasty remnant. Intestinal reconstructive techniques were not an available option for this patient.
