The 30‐day postoperative mortality rate was comparable after laparoscopically completed and converted procedures (0·4 <italic>versus</italic> 0 per cent respectively; <italic>P</italic> = 0·610). Factors significantly associated with morbidity after conversion were smoking, cardiovascular co‐morbidity, previous abdominal operations (particularly colectomy or hysterectomy) and adhesions. Overall morbidity was not affected by conversion (27·0 per cent at 30 days in both groups; <italic>P</italic> > 0·999). However, patients experiencing morbidity tended to have had earlier conversions: median (range) 40 (15–90) min into surgery <italic>versus</italic> 50 (15–240) min for those who did not develop morbidity (<italic>P</italic> = 0·006). The risk of reoperation for postoperative morbidity was higher following conversion because of complications (13 <italic>versus</italic> 2·9 per cent; <italic>P</italic> = 0·024)</bold>.</p> </sec> <sec id="bjs9283-sec-0004" sec-type="section"> <title>Conclusion</title> <p id="bjs9283-para-0004"> <bold>Conversions of laparoscopic colorectal resection are not associated with increased overall morbidity, regardless of the timing of conversion</bold>.</p> </sec> </abstract>
