Large bowel obstruction in a 27-year-old woman caused by a sigmoid faecal bolus.

A 27-year-old woman presented to the emergency department with a 24-hour history of severe left iliac fossa pain associated with vomiting. She reported a history of ovarian cysts and was provisionally diagnosed with a ruptured ovarian cyst and admitted under the obstetrics and gynaecology team for further investigation. 24 hours later, she became haemodynamically unstable with increasing abdominal distention and developed a metabolic acidosis. A CT scan revealed large bowel obstruction (LBO) secondary to a faecal bolus in the sigmoid colon with appearances suggestive of adult-onset Hirschsprung's disease. She underwent an emergency laparotomy and decompressive transverse colotomy and was admitted to the intensive care unit overnight. After discharge, she presented again with small bowel obstruction (SBO) which resolved with conservative management. A follow-up colonoscopy and biopsies showed no anatomical abnormalities to account for the LBO and were inconclusive for Hirschsprung's disease.

A seizure-induced T8 burst fracture re-presenting as an acute abdomen.

A male aged 44 years presented to the emergency department with a 1-week history of intermittent right-sided abdominal pain radiating to the midline. Examination demonstrated a tender right upper quadrant with voluntary guarding and a low grade fever. One week previously, he had been admitted to hospital after an isolated, self-terminating seizure secondary to an deliberate venlafaxine overdose. His upper abdominal symptoms started immediately postseizure but at the time were attributed to musculoskeletal chest pain by the discharging team. Acute cholecystitis was suspected, but liver function tests, amylase and an erect chest radiograph were unremarkable.The abdominal pain responded well to morphine, permitting a thorough reassessment of the patient, which revealed midthoracic spine tenderness, previously undetected. Prior to this, the patient had not complained of any back pain. A CT scan confirmed a burst fracture of T8 requiring urgent transfer to the local spinal unit for posterior stabilisation.
