Second free jejunum transfer after flap loss does not affect oral intake: A retrospective case-control study

Purpose: Free jejunum transfer is one of the standard procedures for restoring oral intake after total pharyngo-laryngo-esophagectomy. Flap loss leading to a second free jejunum transfer rarely occurs. This study investigated the impact of a second free jejunum transfer on post-operative oral intake.

Methods: A retrospective review was conducted on patients who underwent a first free jejunum transfer between July 1998 and December 2019. A total of 367 patients were included in the study. Among them, 17 patients who underwent a second free jejunum transfer because necrosis constituted the second free jejunum transfer group, whereas 350 patients who did not require a second free jejunum transfer formed the first free jejunum transfer group. The incidence of dysphagia requiring tube feeding and post-operative complications was compared between the two groups. Moreover, risk factors for dysphagia and complications were estimated.

Results: There were no statistically significant differences in the incidence of dysphagia post-operation between the two groups. A second free jejunum transfer was a statistically significant factor for complications at 2- and 6-months post-operation; however, there were no significant differences in complication rates at the 12-month follow-up. Furthermore, there were no significant differences in the incidence of severe complications between the two groups.

Conclusion: Although a second free jejunum transfer increases early complications, it is not associated with major complications and does not negatively impact oral intake. These findings support the conclusion that free jejunum transfer is safe and helps maintain post-operative quality of life.
