Esophageal replacement using the colon: is it a good choice?

Area of Science:

• Pediatric Surgery
• Gastroenterology
• Thoracic Surgery

Background:

• Esophageal replacement is a complex procedure for children with esophageal atresia or strictures.
• Colon interposition has been utilized for decades, with various techniques and outcomes.

Purpose of the Study:

• To evaluate the long-term outcomes and complications of colon interposition for esophageal replacement in a pediatric population.
• To assess the efficacy of different surgical approaches and identify factors influencing functional results.

Main Methods:

• Retrospective review of 38 pediatric patients who underwent esophageal replacement between 1962 and 1993.
• Analysis of surgical techniques (right vs. left colon, substernal vs. transthoracic placement), early and late complications, and functional outcomes.
• Long-term follow-up data were collected for 20 patients (53%) over a mean of 12 years.

Main Results:

• Colon interposition, primarily using the right colon (61%), was performed for esophageal atresia and strictures.
• Early complications included cervical anastomotic leaks (29%) and pneumonia. Late complications involved strictures and graft failures (18%).
• Despite complications, 14 patients (70% of those with follow-up) had excellent results, while 17 (45%) required additional procedures.

Conclusions:

• Colon interposition remains a suitable option for pediatric esophageal replacement, offering good functional outcomes in the majority of cases.
• While early complications like anastomotic leaks can occur, they rarely persist long-term.
• Redundant grafts and poor emptying are potential late issues, underscoring the need for vigilant long-term patient monitoring and management.
