Spontaneous Hepatic Hydatid Cyst Rupture Into the Transverse Colon.

Hydatid disease is a prevalent parasitic infestation caused by the cestode Echinococcus granulosus in predominantly rural areas of the Mediterranean region, South East Asia, Australia, and South America. This report discusses a unique case of a 32-year-old lady who presented to the Emergency Surgery Department with complaints of abdominal pain, distension, and constipation for five days. Radiological investigations showed air-fluid levels within a large cyst originating from the liver. Surgical exploration revealed a large hepatic hydatid cyst communicating with the transverse colon with the presence of multiple peritoneal hydatid cysts. Evacuation of the cyst contents, lavage, and excision of the rest of the hydatid cysts was done. Dense adhesions were present involving the liver, large bowel, and duodenum. Therefore, a terminal ileum diversion loop ileostomy was made. Ileostomy was reversed after checking the large bowel anatomy with a distal loopogram.
