A swallow study after gastrectomy is performed to verify what?

A swallow study after gastrectomy is primarily performed to verify the absence of an anastomotic leak. Following a gastrectomy, which involves the surgical removal of part or all of the stomach, a new connection (anastomosis) is created between the remaining stomach and the small intestine or esophagus. This area is particularly vulnerable to leaks, which can lead to serious complications such as peritonitis or sepsis.

The swallow study utilizes contrast imaging to observe how the patient swallows liquids and allows clinicians to assess the integrity of the anastomosis. If a leak is present, the contrast material may escape from the anastomosis into the surrounding area, thereby confirming the leak.

This monitoring is crucial in the postoperative phase because early detection of such complications can significantly impact patient outcomes and guide subsequent clinical interventions. Other potential assessments, such as diet tolerance or obstruction detection, are typically evaluated through different means or at later stages of recovery. Hence, the swallow study's primary role focuses on ensuring the safety and effectiveness of the gastroenteric connection established during the surgery.
