Nonocclusive mesenteric ischemia secondary to organophosphorus poisoning: A case report.

Nonocclusive mesenteric ischemia (NOMI), a rare subtype of mesenteric ischemia, carries high morbidity and mortality due to its delayed recognition. Organophosphorus poisoning (OPP) manifests with varied gastrointestinal symptoms, but ischemia has been described only in a few case reports. Imaging, particularly contrast-enhanced computed tomography (CECT), plays a pivotal role in early diagnosis. We report the case of a 23-year-old male who intentionally ingested an organophosphorus (OP) compound and was admitted to the intensive care unit (ICU). During the course of treatment, he developed signs of peritonitis and was subsequently diagnosed as NOMI on imaging. Surgical exploration confirmed gangrenous bowel, necessitating resection and ileostomy. This case underscores the need to consider mesenteric ischemia as a rare but serious complication of organophosphorus poisoning, where prompt imaging and surgical intervention can be lifesaving.
