Treatment of left‐sided colonic emergencies: a comparison of US and UK surgical practices

Abstract

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. 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. 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. 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.
