BackgroundThe main indications for emergency subtotal colectomy (SC) include management of toxic colitis, refractory haemorrhage and/or perforation. Alternatively, elective surgery is performed for those refractory to medical therapy or with evidence of multifocal dysplasia. Overall, the annual incidence of SC has fallen since the introduction of biologic therapies and we aimed to review our current practices.MethodsA retrospective review of inflammatory bowel disease (IBD) patients undergoing subtotal colectomy between 2013 and 2020 was performed. Medical records, operative notes, discharge summaries, histopathology reports and other supporting documents were reviewed. Indication for surgery, management of the rectum (i.e. maintenance of rectal stump, progression to completion proctectomy or IPAA formation) associated morbidity (Clavien-Dindo classification) and length of hospital stay were examined.ResultsFifty-six IBD patients underwent a subtotal colectomy. Twenty-five patients (UC 14, Crohn's 11) had an elective procedure, and 31 patients (UC 19 Crohn's 12) had an emergency/semi-urgent procedure. Interestingly, 80% (n = 25) of the emergency cohort and 68% (n = 17) of the elective cohort had a laparoscopic resection. Major morbidity (Clavien-Dindo > 2) was higher among the emergency group (39% vs. 24%). Deep surgical site infection was the commonest morbidity (13%) in the emergency group, while superficial surgical site infection was commonest in the elective cohort (20%). Overall, there was no difference in surgical re-intervention rate (13% vs 12%), and there were no perioperative mortalities. Median post-operative length of stay was shorter in the elective cohort (9 versus 13 days).ConclusionA significant proportion of IBD patients still require semi-urgent/emergency colectomy, which is associated with considerable length of stay and morbidity. The results of our study provide real-world outcomes to help counsel patients on expected outcomes.© 2022. The Author(s), under exclusive licence to Royal Academy of Medicine in Ireland.
