RESUMO
An abscess is a collection of pus (dead and dying neutrophils plus proteinaceous exudate) that has built up within the tissue of the body. Mesenteric abscess is a rare, usually accounts for small percentage of intra-abdominal abscess after inguinal hernia surgery which is presented as left iliac fossa mass in postoperative period of open inguinal hernia surgery of left side and also presented with undescended testis of left side which is actual cause of formation of inguinal hernia of same side. Late onset mesh infection and post-operative peritonitis are very common in case of open hernia surgery. Intra-abdominal abscess cause significant morbidity and mortality. Surgery disturb the equilibrium between coagulation and fibrinolysis in the abdominal cavity in favour of coagulation system. Diminished fibrin degradation is a common pathway for the formation of abscess. We present a case of 40 years of male came with pain in left iliac fossa and lower abdomen for last 2 months with a swelling at LIF and hypogastric region for last 3 months with a previous history of hernia surgery of left side 2 month back which was diagnosed as mesenteric abscess and treated with exploratory laparotomy under general anaesthesia and abscess was drained.
RESUMO
Cases showing complications such as esophageal injury, deep neck infection, and mediastinitis caused by accidental ingestion of fish bone are common. But ingestion of fish bone rarely causes perforation of the gastrointestinal tract or an intra-abdominal abscess. We report herein a case of a 78-year-old man with a periumbilical mesenteric abscess caused by fish bone which was ingested unconsciously. The fish bone was found in the terminal ileum and it was removed by colonoscopy. The patient improved and he was discharged after systemic antibiotic therapy. Occasionally, when patients swallow fish bone without a foreign body sensation, clinicians should suspect perforation caused by fish bone in case of an intra-abdominal abscess of unknown cause.
