Liver abscess caused by fish bone perforation of Meckel’s diverticulum: a case report

Abstract

Background: Liver abscess due to gastrointestinal perforation by foreign bodies is rare. Furthermore, there are few case reports of liver abscess via the portal vein caused by perforation of the lower gastrointestinal tract by a foreign body. Case presentation: A 54-year-old man visited our hospital because of a fever that had lasted for 1 month. There were no physical findings except for the fever. Laboratory tests showed only elevated inflammatory markers. Abdominal contrast-enhanced computed tomography revealed an abscess in the right lobe of the liver and a highdensity object in the small intestine. We diagnosed him with liver abscess secondary to intestinal perforation by a foreign body. The patient underwent drainage of the liver abscess and laparoscopic surgery for perforation of the small intestine. A fish bone had perforated the top of Meckel's diverticulum, which had been covered by the ileal mesentery. We successfully performed diverticulectomy and removed the fish bone. The patient was discharged without complications on the 13th postoperative day. Conclusions: Liver abscess caused by foreign bodies requires multidisciplinary treatment, so we must detect and remove the cause of the abscess earlier. Liver abscess can form via the portal vein secondary to lower gastrointestinal perforation, as in this case. When exploring the cause of liver abscess, we should investigate the whole body, including the lower gastrointestinal tract.

Pyogenic liver abscess secondary to gastric perforation of an ingested toothpick: A case report

“…Most ingested foreign bodies are excreted without injury to the GI tract, and foreign body-induced GI tract perforation is a rare event occurring in less than 1% of all cases[ 3 ]. Liver abscess formation due to foreign body-induced GI perforation is even rarer, with less than 100 cases reported to date[ 4 , 5 ].…”
