Summary

A novel esophageal dissector simplifies thoracic esophagus mobilization without thoracotomy. This instrument facilitates easier and faster dissection, reducing operative time and avoiding hypotension or arrhythmia during procedures.

Area of Science:

  • Surgical Innovation
  • Gastrointestinal Surgery
  • Thoracic Surgery

Background:

  • Describes a novel instrument for esophageal mobilization, avoiding thoracotomy.
  • The device is a metal ring introduced via the neck to encircle and separate the esophagus.

Purpose of the Study:

  • To evaluate the safety and efficacy of a new esophageal dissector.
  • To assess the instrument's utility in mobilizing the thoracic esophagus.

Main Methods:

  • Preliminary cadaver studies (12) followed by clinical application in 20 patients.
  • Patients had esophageal carcinoma or benign esophageal lesions.

Main Results:

  • Esophageal mobilization was easier and less time-consuming.
  • No hypotension or arrhythmia observed during dissection.
  • Complications included pneumothorax (20%), transient recurrent laryngeal nerve palsy (25%), and two thoracotomies for bleeding.

Conclusions:

  • The esophageal dissector simplifies thoracic esophagus mobilization.
  • The instrument is contraindicated for upper/middle esophageal lesions or bulky esophagi (e.g., achalasia).
  • This palliative treatment precludes radical curative attempts.
