ABSTRACT

BACKGROUND: Extralobar pulmonary sequestrations (EPS) are a rare benign congenital bronchopulmonary foregut malformation. Complete resection is necessary to confirm the diagnosis with histopathologic examination. The aim of this study was to describe the laparoscopic minimally invasive surgery (MIS) for a small series of ectopic EPS in small children and to show its feasibility and safety. METHODS: From January 2001 to December 2008, 12 cases of EPS were prenatally diagnosed and retrospectively reviewed. From this group, we isolated 6 children with ectopic EPS. Ages ranged from 15 days to 14 months. Three infants were symptomatic, and the others showed persistence of the lesion with parental anxiety. All prenatal diagnoses were confirmed by postnatal Doppler ultrasound and intravascular contrast computed tomography scan with 3-dimensional reconstructions. Postnatally, all were ectopic lesions: 3 were hiatal and intradiaphragmatic, 3 infradiaphragmatic and left paramedian. Laparoscopic MIS consisted of 4 small trocars and low-pressure pneumoperitoneum. We carried out a retroesophageal dissection in 4 cases, an elective control of systemic vessels, and a removal of the EPS with histologic study. RESULTS: We performed 5 procedures laparoscopically and 1 thoracoscopically. There were 2 abdominal conversions. Nevertheless, no intraoperative or immediate postoperative complications occurred. Hospital stay ranged from 1 to 5 days (mean, 2.7 days). The diagnosis of pure pulmonary sequestration with feeding vessels in 5 cases was confirmed by histopathology. Follow-up ranged from 13 to 84 months (mean, 43 months). Late complications were benign. CONCLUSIONS: Laparoscopic MIS for ectopic EPS in small children is a feasible and safe technique. The great magnification provided by the endoscopic procedure allows for the search of associated congenital anomalies, meticulous retroesophageal dissection, and control of the systemic vessels. Resection provides definitive diagnosis and treatment, and confers the benefits of a minimal access technique.

ABSTRACT

BACKGROUND AND OBJECTIVE: The exact timing of the evolution of lesion volumes of invasive pulmonary aspergillosis (IPA) on CT scan images could be helpful in the management of hematological patients but has never been evaluated in a prospective study. We analyzed the CT scan data from the prospective Combistrat trial. DESIGN AND METHODS: Volumes of aspergillosis lesions from 30 patients (including 24 acute myeloid leukaemia) with probable (n=26) or proven (n=4) IPA according to the EORTC-MSG modified criteria, were measured prospectively on the thoracic CT scans at the enrolment in the study on day 0 (D0), D7, D14 and end of treatment (EOT). RESULTS: For the overall population, the volume of pulmonary aspergillosis lesions increased significantly from D0 to D7 (1.6 fold; p=0.003). Then this volume decreased significantly from D7 to D14 (1.36 fold at D14 with p=0.003 for D14 vs. D7, but with p=0.56 for D14 vs. D0). At EOT (= D17, median value), the volume of lesions was significantly lower than D14 (0.76 fold the initial volume; p<0.001) but it was not significantly different when compared to D0 (p=0.11). CONCLUSIONS: The results of this prospective study suggest that the sequential analysis of CT scan in neutropenic patients with IPA depicts more precisely the evolution of lesion volumes than comparison to baseline images. Moreover, the systematic use of chest CT appears to be a useful tool for diagnosis and outcome evaluation of IPA in clinical trials.
