Laparoscopic removal of an abdominal extralobar pulmonary sequestration

Ectopic extralobar pulmonary sequestrations in children: interest of the laparoscopic approach

“…They have a male predominance of 3:1, compared with 1.5:1 in intralobar BPS [1]. Associated congenital anomalies were found in 65% of EPS after autopsy studies [4].…”

“…Exact embryologic pathogenesis of BPS is unknown. It could be explained by accessory lung bud development after the 4th week of gestation, with a second ectopic lung bud arising from the primitive foregut and acquiring its own autonomous systemic blood supply [3][4][5][6]. If the bud arises in late embryonic life, after development of the pleura, it grows separate from the adjacent nascent lung, is invested by its own pleura, and becomes an extralobar sequestration [6].…”

“…Bronchopulmonary sequestrations have an underestimated incidence of 1 in 1000 births [1], varying from 0.15% to 1.8% [3][4]. Prevalence is not actually known.…”

Prenatal Diagnosis of an Extralobar Infradiaphragmatic Pulmonary Sequestration: A Case Report and Review of the Literature

“…On the other hand, those Depending on the level of the foregut at which they emerge, extralobar PSs may be supradiaphragmatic or, rarely, infradiaphragmatic (i.e., intraabdominal), with an approximate ratio of 9 to 1, respectively. According to several reports, intraabdominal pulmonary sequestrations (IPSs) are typically situated in the left suprarenal area [4,[6][7][8]. Extralobar PSs are associated with other congenital malformations in more than 50% of cases, such as congenital diaphragmatic hernias, congenital adenomatoid malformation type II, and congenital heart disease [9].…”

Infarction of extralobar pulmonary sequestration after blunt trauma

“…Excision of asymptomatic pulmonary sequestration has been advocated because of the risk of infection and hemorrhage [6,7]. A thoracoscopic approach for congenital lung lesions has also been reported with increasing frequency [8][9][10]. Surgical resection of pulmonary sequestration carries very low morbidity and excellent long-term outcome [3].…”
