A case of secondary gastric wall abscess due to perforation from advanced colonic cancer successfully treated by endoscopic endoprostesis using endoscopic retrograde biliary drainage tube

Abstract

A 44 year-old man was admitted to our hospital because of severe left upper abdominal pain and high fever. Blood examinations revealed high levels of white blood cell count and CRP. An abdominal enhanced CT scan showed a low-density mass with an enhanced margin at the posterior side of the gastric body, and an irregular mass nearby at the transverse colon. We diagnosed a gastric wall abscess due to perforation from advanced colonic cancer and performed endoscopic drainage and endoprostesis by ERBD tube insertion into the abscess through the gastric wall. After the procedure, the clinical symptoms and laboratory data improved quickly, and we could continue further examinations and proceed safety with the treatment plan. To our knowledge, this is the first reported case of a gastric wall abscess due to penetration by gastrointestinal tract cancer which was treated with endoscopic endoprostesis.
