Ascariasis causing small bowel obstruction in an adult female: A case report

Le résumé fourni par la source

INTRODUCTION AND IMPORTANCE: Ascariasis is a helminthic infection of humans caused by Ascaris lumbricoides. Intestinal obstruction from ascariasis can result in a rare but severe and often fatal surgical emergency of intestinal perforation and peritonitis in endemic areas. There have been reports of ascariasis causing Small Bowel Obstruction (SBO) in children in endemic areas but this phenomenon has not been studied in adults. The objective of this study was to describe the case of ascariasis causing SBO in a 25-year-old female. CASE PRESENTATION: A 25-year-old female from southwest Ethiopia presented with a complaint of intermittent crampy abdominal pain of 02 days duration associated with vomiting of ingested matter of 02 to 03 episodes, progressive abdominal distension and failure to pass feces and flatus. On examination, she was acutely sick looking. She has mild abdominal distention and a hyperactive bowel sound. Subsequently, she was resuscitated, broad spectrum antibiotic started, consent taken & operated. Patient discharged on the 7th postoperative day. CLINICAL DISCUSSION: There have been reports of Ascariasis causing SBO in endemic areas of the tropics and sub-tropics. SBO secondary to the ascaris ball in an adult is very rare and is relevant to present as it adds key clinical lessons in the consideration as a differential diagnosis, investigation clues and patient management. CONCLUSION: In a patient presented with symptoms and signs suggestive of bowel obstruction, Ascariasis should be considered as a differential diagnosis for those from endemic areas. The treating physician should have a high index of suspicion.
