BACKGROUND: Surgeons are increasingly considering resection and primary anastomosis when treating left-sided colonic obstruction or perforation in preference to the more traditional staged procedures. Previous studies in the United Kingdom (UK) and United States of America (USA) have suggested a greater interest in single-staged procedures amongst UK surgeons. This study was aimed to directly compare the treatment preferences between UK and US surgeons. METHOD: A questionnaire, designed to determine the procedure of choice when faced with left-sided colonic emergencies in patients with good and poor anaesthetic risk, was sent to 500 surgeons in the UK and 500 surgeons in the USA. RESULTS: UK surgeons were more likely to perform resection, primary anastomosis and on-table colonic lavage in patients with sigmoid obstruction (good anaesthetic risk: P < 0.0001; poor risk: P < 0.01) and sigmoid perforation (good risk: P < 0.0001). In good-risk patients with sigmoid obstruction, US surgeons were more likely than UK to choose Hartmann's procedure (P < 0.0001). US surgeons performing primary anastomosis were less likely to perform on-table lavage. CONCLUSION: Single-stage procedures are widely accepted as viable treatment options in both the UK and the USA when dealing with left-sided colonic emergencies. British surgeons are more likely to favour single-staged procedures, particularly with on-table colonic lavage, when compared with US surgeons.
