  • Title: [Results of the surgical treatment of severe caustic pharyngo-esophageal stenosis. The value of complete reconstruction of the pharynx by transposition of the ileum and colon].
    Author: Popovici Z.
    Journal: Chirurgie; 1998 Dec; 123(6):552-9. PubMed ID: 9922594.
    Abstract:
    STUDY AIM: The aim of this study was to report the results of pharyngoesophageal reconstruction in extensive corrosive strictures and to describe an original conception concerning extensive chemical burns of the pharynx with involvement of the epiglottis, oro-hypopharyngeal junction and cricopharyngeal pinchcock. PATIENTS AND METHODS: A personal series of 253 esophageal reconstructions using the colon and ileum is reported. In 124 patients, the cervical anastomosis of the graft was performed at the level of the pharynx, and these cases with extensive pharyngeal lesions were the basis of this study. The anastomosis was performed with the hypopharynx in 27 patients, with the oropharynx in nine and a total reconstruction of the pharynx or "pharyngoplasty" was carried out in 69 patients. The pharyngoplasty was classified according to the approach, in anterior, posterior, lateral, superior (transmandibular) and inferior. In high strictures with epiglottic injury, epiglottectomy was necessary in order to prevent recurrence. A visceral pharyngoplasty was performed in 61 patients, using the colon in 42 and the ileum in 19, a skin reconstruction in six patients and a myocutaneous flap in two. RESULTS: The global postoperative mortality rate was 4.7%. Stenosis of the cervical anastomosis occurred in 4.9% of the whole series. With a follow-up from 6 months to 10 years, 70% of the patients resumed a normal oral diet, 21% had mild symptoms and 7% had poor results (patients with tracheostomy and gastrostomy). CONCLUSION: Extensive chemical burns of the pharynx are very severe and their treatment very difficult. For the author, total visceral pharyngeal reconstruction is considered to be the procedure of choice, using ileopharyngoplasty with realization of an ileal pouch. Good results were obtained in 70% of the patients with extensive corrosive strictures.
