title: Role of retrograde dilatation in the management of pharyngo-esophageal corrosive strictures.
abstract: Pharyngo-esophageal corrosive stricture is a complex clinical scenario. If an esophageal opening cannot be found orally through endoscopy, a retrograde approach with a mini-laparotomy and gastrostomy should be attempted. This study primarily aimed at defining the role of preoperative retrograde dilatation of pharyngo-esophageal corrosive strictures. A retrospective analysis of 51 cases of pharyngo-esophageal corrosive strictures identified between 1997-2005 was performed. The demographic details were analyzed. The details of the injury to the pharynx either in isolation or in combination were noted and the management details were recorded. In 21 patients preoperative retrograde dilatation was considered and the technique was successful in 14 (Group I). In seven the technique failed (Group II) and these patients underwent transhiatal resection and gastric pull-through and/or retrosternal pharyngocoloplasty. In Group I patients the postoperative stay was significantly less than in Group II (12 +/- 2.03 days vs. 18 +/- 4.32 days; p = 0.001) Recurrent aspiration, respiratory tract infections, choking sensation and the need for tracheostomy were less frequent in Group I. The overall functional assessment was good in Group I. For treatment of pharyngo-esophageal obstruction, if antegrade dilatation is not possible due to technical reasons, retrograde dilatation is a viable option before opting for organ replacement/bypass procedures. There is no best replacement of the native organ to maintain quality of life.
