Free Jejunal Graft Repair after PharyngoLaryngo-Esophagectomy-Risk Factor Analysis for Postoperative Dysphagia

Postoperative mechanical bowel obstruction after pharyngolaryngectomy for hypopharyngeal cancer: Retrospective analysis using a Japanese inpatient database

“…Our study had several limitations. First, the follow‐up duration was shorter than previous studies of postoperative abdominal donor‐site complications after pharyngolaryngectomy (means 9 months vs 2‐29 months) . Because mechanical bowel obstruction can develop at any time during a person's life, the risk may have been underestimated.…”

“…Previous studies that evaluated abdominal donor‐site complications after pharyngolaryngectomy were all from a single institution, with surgery performed by one to several head and neck surgeons . The incidence proportions in those studies ranged from 2.4%‐13%.…”

“…To date, several studies have evaluated donor‐site complications after the harvesting of a free jejunum graft . However, their results were limited because they were based on a single institutional experience and the sample sizes (n = 30‐313) were not large enough to capture the rare occurrence of donor‐site complications.…”

Quantitative assessment of the free jejunal graft perfusion

“…Although microvascular reconstruction has greatly improved, there remains much room for improvement and further study. Particularly, the rate of graft failure mainly as a result of graft malperfusion is between 3% and 24% [3,4,15]. A necrotic FJG transferred to the neck is a life-threatening complication because it is adjacent to major vessels, such as the carotid arteries and the jugular veins, that can become infected by necrotic tissue.…”

Endoscopic balloon dilatation for pharyngo‐upper esophageal stricture after treatment of head and neck cancer

“…Consistent with our results, previous studies have reported that strictures usually occurred at the distal esophageal anastomosis and, thus, the distal site may be more commonly affected because of its narrower lumen. Additionally, CRT could be an additional risk factor for stricture formation at that location . CRT causes mucosal injury and toxicity, so‐called mucositis, which is the initiating event in a cascade leading to a mucosal fibrotic stricture …”
