Pharyngo-cervical esophageal reconstruction.

Area of Science:

• Oncology
• Surgical Reconstruction
• Gastroenterology

Background:

• Advanced hypopharyngeal and cervical esophageal carcinoma present poor prognoses.
• Pharyngolaryngo-cervical esophagectomy is a palliative treatment option for these advanced cancers.
• Reconstruction of the resulting defect has evolved over time.

Purpose of the Study:

• To review current microsurgical reconstruction techniques for pharyngolaryngo-cervical esophagectomy defects.
• To assess the available data on postoperative swallowing function and speech rehabilitation outcomes.
• To identify gaps in knowledge regarding the impact of reconstruction methods on functional outcomes.

Main Methods:

• Review of current microsurgical techniques, including jejunal free flaps and free skin flaps.
• Analysis of existing literature regarding surgical complication rates.
• Assessment of data availability on postoperative swallowing function and speech outcomes.

Main Results:

• Microsurgical techniques, particularly jejunal free flaps, are frequently used for circumferential defects.
• Surgical complication rates are generally considered acceptable.
• There is a lack of quantitative data on postoperative swallowing function and the impact of reconstruction on speech.

Conclusions:

• While microsurgical reconstruction is standard for advanced esophageal cancer resection, functional outcomes require further investigation.
• More research is needed to quantify swallowing function after different reconstruction methods.
• The effect of various surgical reconstruction techniques on speech rehabilitation remains poorly documented.
