Official Title: First Laparoscopy or Active Observation in Acute Non-specific Abdominal Pain: The FLO Trial
Brief Summary:
Patients with acute abdominal pain comprise a significant proportion of attendances at emergency departments. These patients account for about a third of general surgical admissions in a typical day. In some cases, the diagnosis is clear from baseline investigations (for example in cases of pancreatitis). In other cases, the diagnosis remains unclear but there are signs that necessitate urgent surgery (for example in cases of appendicitis). A final group exists where no clear explanation for the pain is found and where there are insufficient clinical signs to warrant surgery. These patients are said to have "non specific abdominal pain" (NSAP) and present a management dilemma.
Traditionally such patients are managed with a strategy of active observation. Patients are examined at regular intervals and may undergo imaging. In some cases, symptoms and signs progress and surgery is needed while in other cases resolution may occur or a diagnosis may be reached non-operatively allowing focused medical treatment. Recently, two alternative strategies have emerged. Early cross-sectional imaging using CT scanning may identify conditions whilst being non-invasive. This would allow diagnosis and treatment would follow. The alternative strategy of early laparoscopy (key hole surgery) offers the possibility of concomitant therapy, but is invasive.
The study hypothesis is that in patients with acute non-specific abdominal pain active management with laparoscopy on admission will reduce hospital stay and costs when compared to traditional active observation, without increasing complications.
