Reducing complications in reconstruction of the cervical esophagus with anterolateral thigh flap: The five points protocol.

Patients suffering from hypopharyngeal cancer commonly present in the advanced stage and undergo a circumferential pharyngolaryngectomy. The possibility to reconstruct the esophagus and achieve an oral alimentation can significantly reduce the additional burden of a jejunostomy. The cervical esophagus is usually reconstructed with jejunal free flap (JFF) or fasciocutaneous free flap such as the anterolateral thigh (ALT) free flap. The latter has proved its donor-site safety and fast recovery. However, it is burdened by a high fistula rate. We present our five points protocol for reducing fistula rate and improving outcome. Twenty-eight patients underwent total pharyngolaryngectomy and required esophageal reconstruction with ALT flap from 2015 to 2020. In each patient, we performed five adjustments: a thicker dermal layer, a two-layer closure, a barrier from the tracheostomy, a nonabsorbable monofilament suture, and two NG tubes to enhance neoesophageal drainage. Twenty-five (89%) patients returned to solid or soft food diet after the reconstruction. Three patients had liquid diet. Contrast media leakage was observed in only 2 (7%) patients during esophagography at three weeks, with only one needing surgical revision. Our five points protocol for ALT reconstruction of cervical esophagus proved to be effective in achieving an incredibly low rate of complications, without the burden of significant donor-site complications.
