Effects of perioperative radiation treatment on stricture and fistula formation in hypopharyngeal reconstruction: a meta-analysis.

Hypopharyngeal reconstruction is a surgically challenging procedure, and postoperative management is important due to a high rate of complications following surgery. In particular, stricture and fistula formation is the most common long-term postoperative complication. Through systematic review and meta-analysis of 21 studies, a significant radiation effect of stricture and fistula formation was found in patients who underwent hypopharyngeal reconstruction. The perioperative radiation must be seen as a critical factor for stricture and fistula formation in hypopharyngeal reconstruction.
