Use of tubed gastro-omental free flap for hypopharynx and cervical esophagus reconstruction after total laryngo-pharyngectomy.

In case of total laryngo-pharyngectomy (TLP), replacement of the pharyngoesophageal segment is more often done with jejunal flap; however, in some cases, this flap doesn't represent the best surgical technique of reconstruction. The tubed gastro-omental free flap (TGO) offers an alternative procedure in selective cases. The objective of the study was to assess the TGO as a method of pharyngoesophageal reconstruction. Our study was based on a literature review and a retrospective study of six consecutive cases of TGO reconstruction after TLP. Six patients aged from 52 to 70 years underwent TGO reconstruction after TLP. Five patients had previously received systemic chemotherapy and external irradiation at curative doses, and three had undergone previous surgery. No abdominal complication occurred. Partial necrosis of the gastric flap occurred in one case. Except for this case, the feeding tube could be removed after 15 days. One patient was successfully treated with pneumatic esophageal dilatation for stricture 2 months after surgery. Four patients died of loco-regional tumor evolution or distant metastatic disease. For both of the patients who survived (mean follow-up, 40 months), a normal diet and an esophageal voice were obtained. The TGO offers a safe method of reconstructing the pharyngoesophageal segment in a surgical field compromised of previous multimodal therapy.
