Abstract

Methylene blue (MB) based chromoendoscopy has been used for more than a decade to increase detection rates of specialized intestinal metaplasia, dysplasia, and esophageal adenocarcinoma. It is also used to detect anastomotic leakage after an operation. A 67-year-old man with no previous medical problems had complaints of jaundice and weight loss for 2 months. He was diagnosed with a Klatskin tumor and was referred to our hospital. An initial esophagogastroduodenoscopy (EGD) was performed before the operation. No abnormality was observed in the esophagus. MB solution was infused via an L-tube to check for leakage in the anastomosis. Subepithelial hemorrhagic and edematous mucosal changes with friability and a bluish mucosal discoloration were noted 2 days later from the mid to lower esophagus on EGD. Nine months later, an EGD revealed an unremarkable esophageal mucosa. MB solution is considered safe; however, a large volume or high concentration of MB solution might be harmful.

메틸렌 블루 용액을 이용한 색소내시경은 식도점막의 장상피화생(specialized intestinal metaplasia)인 바렛식도, 이형성증과 식도샘암종의 진단율을 높이기 위해 사용하며 장절제 후 문합부 유출 등의 진단 목적으로 메틸렌 블루 용액을 사용하고 있다. 메틸렌 블루 용액은 일반적으로 안전한 것으로 알려져 있으나 저자들은 수술 후 문합부 유출 진단을 위해 사용한 대용량의 메틸렌 블루 용액 사용 후 발생한 급성 식도점막 손상 1예를 경험하여 보고하는 바이다. 이러한 부작용에 대한 가능성을 숙지하여야 하며, 가능한 적정 농도와 용량을 사용하고 용액 사용 후 가능한 빨리 저류된 용액을 흡인하여 제거한다면 이러한 부작용을 최소화할 수 있을 것으로 생각한다.
