Postoperative Complications in Children With Crohn Disease Treated With Infliximab.

OBJECTIVES: Infliximab (IFX) has become a mainstay of therapy for children with Crohn disease (CD). Despite medical advances, many children with CD, however, still require operative interventions. The risk of complications following resection in children treated with IFX remains largely unknown. We compare surgical outcomes stratified by IFX therapy in a cohort of children with CD who require bowel resection. METHODS: We reviewed the postoperative complications in 123 children with CD who underwent bowel resection with primary anastomosis at our institution between 1977 and 2011. Demographics, medications, types of operations, and inpatient courses were analyzed. Complications and length of stay were compared based on medical therapy. RESULTS: Overall, the postoperative complication rate was 13%. Of the 123 surgical cases, 24 children had received IFX before their operation. In the children treated with IFX, we identified 3 major complications, including anastomotic leak, acute renal failure, and intraabdominal abscess. There were 9 major complications in the non-IFX group, including infections (2), intraabdominal abscesses (2), bowel obstruction, shock, supraventricular tachycardia, phlegmon, and anastomotic stricture. No significant differences in complication rates or postoperative lengths of stay were identified between those who did or did not receive IFX. CONCLUSIONS: In this cohort, surgical procedures in children and young adults treated with IFX were not associated with an increased number of complications or prolonged length of stay. Given that postoperative complications are infrequent in children, larger multicenter studies may be required to determine whether IFX therapy increases the risk of surgical complications in pediatric CD.

Treatment of appendicitis in neutropenic children.

BACKGROUND: Appendicitis in the neutropenic patient places the clinician in a precarious position; balancing the timing and risks of surgery and the risk of an uncontrolled infectious source in the abdomen. METHODS: Multi-center retrospective review from 2000 to 2010 of appendicitis occurring in patients with neutropenia secondary to chemotherapy. Patient demographics and surgical outcomes were tracked. RESULTS: There were 11 patients, mean age of 11 y (3-17 y); six were male. Mean weight was 46.9 kg (18.1-72.6 kg). Mean body mass index was 20.9 kg/m(2) (16.8-27.3 kg/m(2)). There were five acute lymphocytic leukemias, four acute myeloblastic leukemias, one T-Cell lymphoma, and one Ewing's sarcoma. Mean presenting white blood cell count was 1900 (0.2-4.4). Average absolute neutrophil count was 900 (0.00-2.6). Computed tomography scan was used in all patients. Appendectomy was performed within 24 h of presentation in all patients, three were perforated. Mean time to first feeding was 1 d (range, 0-5 d), goal feeds at 3 d (range, 1-6 d ). Mean length of stay from appendicitis was 4 d. CONCLUSION: Early appendectomy for appendicitis in neutropenic patients appears to be tolerated well with a low risk of surgical complications.

Early results of an objective feedback-directed system for the staged traction repair of long-gap esophageal atresia.

PURPOSE: Treatment of long-gap esophageal atresia challenges pediatric surgeons. Dr. Foker described utilization of external traction sutures to promote in-vivo growth through tension-induced lengthening, but reproducibility of this technique is difficult. We describe a safe and reproducible traction system using transduction of hydrostatic pressure as a surrogate for tension. METHODS: We conducted a multi-institutional review of patients treated with this system from 2005 to 2012. All children had sutures applied to both pouches with continuous measurement of associated hydrostatic pressures (tension). Main outcome measures were days to delayed primary repair and thoracotomies prior to primary repair. RESULTS: Seven children were included. Median time to delayed repair was 15 days (range: 6-47 days). Three patients required repeat thoracotomies owing to mechanical entrapment of a pouch, all identified early by this system. All required postoperative dilations. Three had self-limited postdilation leaks, and there was one operation-related leak. CONCLUSIONS: This system provides reproducible traction application, facilitating staged primary repair by preventing major failures through limiting excessive traction and guides re-exploration for trapped segments. Larger studies are needed to determine the optimal tension protocol, prevent postoperative leaks, while decreasing the need for dilations and time to enteral feeding.
