Internal Supravesical Hernia Revealed by Small Bowel Obstruction

Small bowel obstruction secondary to ingested fish bone is an exceedingly rare occurrence, particularly among the elderly, accounting for less than 1% of cases necessitating surgical intervention. This article reports a case of an 84-year-old male who presented with acute abdominal pain and bilious vomiting for seven days after accidentally swallowing a fish bone. Computed Tomography (CT) of the abdomen and pelvis indicated sub-acute bowel obstruction, revealing a linear foreign body in the jejunum with a focal collection. An emergency exploratory laparotomy uncovered a pocket of pus containing the fish bone in the mesentery of the jejunum, with evidence of perforation at approximately 150 cm distal to the duodenojejunal flexure.
