    Abstract:
    Introduction Total colectomy and ileorectal anastomosis can result in significant defecatory frequency and poor bowel function. The aim of this study was to assess whether a laparoscopic approach is associated with any improvement in this regard. Methods A single institution retrospective review was undertaken of patients undergoing elective total colectomy and ileorectal anastomosis between 2000 and 2011. Those undergoing emergency surgery and paediatric surgery were excluded. The primary outcome measure was satisfactory defecatory function after surgery. Results Forty-nine patients (24 male, 25 female) were included in the study. The median age was 48 years (range: 20-83 years). Laparoscopic total colectomy (LTC) was performed in 20 patients and open total colectomy (OTC) in 29 patients. Indications for surgery were slow colonic transit (n=17), colorectal cancer (CRC) (n=17), CRC with hereditary colorectal cancer syndrome (n=8), inflammatory bowel disease (n=4) and diverticular disease (n=3). In the LTC group, 85% had a satisfactory defecatory frequency of 1-6 motions per day compared with 45% in the OTC cohort (p=0.006). There was no statistically significant difference in bowel frequency related to primary pathology (benign vs cancer surgery, p=1.0). Postoperative complications for both groups included relaparotomy (n=3), anastomotic leak (n=2), small bowel obstruction (n=2), postoperative bleeding (n=1) and pneumonia (n=1). Conclusions This study indicates that long-term defecatory function is better following LTC than following OTC and ileorectal anastomosis. The mechanism for this improvement is unclear but it may relate to the underlying reason for surgery or possibly to reduced small bowel handling leading to fewer adhesions after laparoscopic surgery.
