Sudden onset of severe abdominal pain and distension, nausea, vomiting, and constipation. It is characterised by its rapid progression.
Almost invariably, yes. It requires urgent treatment, which may start with endoscopic decompression for sigmoid volvulus, but often necessitates surgery to untwist and potentially resect the affected segment.
