GASTRIC ANTRAL PATCH OESOPHAGOPLASTY FOR IATROGENIC TRACHEO-OESOPHAGEAL FISTULA

ANZ JOURNAL OF SURGERY, Issue 4 2007
Michael L. Talbot
Acquired tracheo-oesophageal fistula is a devastating condition, usually occurring as a late manifestation of oesophageal or other thoracic malignancies. In these cases palliation by placement of an oesophageal stent is the preferred option, but management of a large non-malignant fistula is more complex. In many patients in whom primary repair of the defects is not possible oesophagectomy may be seen as the best treatment. We present a case of a large tracheo-oesophageal fistula repaired with a gastric antral patch oesophagoplasty and intercostal muscle flap. [source]

Separation between the digestive and the respiratory lumina during the human embryonic period: morphometric study along the tracheo-oesophageal septum

JOURNAL OF ANATOMY, Issue 1 2001
JOSEP NEBOT-CEGARRA
An isolated tracheo-oesophageal fistula could be caused by close proximity of the epithelia of both organs (O'Rahilly & Müller, 1984; Kluth et al. 1987) at certain embryonic stages, the most frequent location being the tracheal bifurcation. Thus the relative position and degree of separation between the digestive and the respiratory tubes throughout their development may be relevant to the origin of this anomaly. The aim of this study was to analyse along the different segments of the tracheo-oesophageal septum (TES) where the closest relationship between both lumina occurred and what degree of separation was present at each segment. Computer imaging techniques were applied on cross sections of a graded series of normal human embryos (Carnegie stages (CS) 13,23). In addition, the differentiation of the primitive TES was also studied (from CS 12) by light microscopy. Between CS 13 and 16 both tubes tended to separate (phase of separation), principally at the proximal segments of the laryngopharyngeal and the tracheo-oesophageal portions of the TES. During this phase the separation between the trachea and oesophagus was wider than between the larynx and pharynx. From CS 17 to CS 23 the digestive and respiratory lumina reached their widest separation at different levels of the laryngopharyngeal portion. Below these levels they tended to come closer together, principally at the proximal segment of the tracheo-oesophageal portion, but also at the distal part of the laryngopharyngeal portion. During this phase of approximation they reached their closest relationship at the proximal (CS 17) and the distal (from CS 18) segments of the tracheo-oesophageal portion. When finally the distal segment of the trachea (which includes the bifurcation) comes closest to the oesophagus, the coats of both organs have already undergone an appreciable differentiation. According to these observations, the origin of the most frequent isolated tracheo-oesophageal fistula at the bifurcation region could not be explained from the normal development of the TES.

Severe epiglottic prolapse and the obscured larynx at intubation

PEDIATRIC ANESTHESIA, Issue 6 2002
F.M. Vaz FRCS BSC (HONS)
Summary Laryngomalacia is the most common congenital anomaly of the larynx and usually involves prolapse of the arytenoids, so-called `posterior laryngomalacia'. Most cases resolve with growth of the child and maturation of the larynx, although, rarely, significant airway obstruction can be present. Severe laryngomalacia preventing intubation is rarely encountered. We report a case of a difficult emergency intubation secondary to `anterior laryngomalacia' in a 4-month-old boy in whom the epiglottis prolapsed posteriorly and became trapped in the laryngeal introitus. The child was referred with a diagnosis of laryngeal atresia on the basis of the intubating laryngoscopic view of no apparent epiglottis or laryngeal inlet. The child was transferred with a tube in the oesophagus that kept the child oxygenated. At the time, oxygenation was felt to be due to a coexisting tracheo-oesophageal fistula, although this was eventually found not to be the case. [source]

GASTRIC ANTRAL PATCH OESOPHAGOPLASTY FOR IATROGENIC TRACHEO-OESOPHAGEAL FISTULA

An overview of isolated and syndromic oesophageal atresia

CLINICAL GENETICS, Issue 5 2007
D Geneviève
Oesophageal atresia (OA) and/or tracheo-oesophageal fistula (TOF) are frequent malformations observed in approximately one in 3500 births. OA/TOF can be divided clinically into isolated OA (IOA) and syndromic OA (SOA) when associated with other features, the most frequent being cardiac, limb and vertebral malformations or anal atresia. SOA is observed in 50% of patients and can be subdivided into several causative groups comprising environmental agents, chromosomal disorders, malformative associations (CHARGE syndrome and VATER/VACTERL association), and other multiple congenital anomaly disorders. The observation of chromosomal disorders with SOA, as well as mouse models of OA provide support for the involvement of genetic factors in OA. Yet, epidemiological data (twin and family studies) do not support the major role of genetic factors in the majority of cases of IOA but rather a multifactorial model. However, several genes involved in SOA have been recently identified, namely N-MYC, SOX2, and CHD7 involved in Feingold (MIM 164280), anophthalmia-oesophageal-genital (MIM 600992) and CHARGE syndromes respectively (MIM 214800), suggesting that OA/TOF, at least in their syndromic forms, may be a highly genetically heterogeneous group.
